Static balancing valve for heating systems. Appointment and features of the balancing valve. Types of static valve

In heating systems, it is simply obliged to attend static balancing valve. It is used to regulate and limit the heat carrier. Using such valves to save a large number of Electricity.
That energy consumption that is needed for the presence of one or another temperature is spent, not exceeding it. In the presence of this element, the service life of the system increases and its continuous operation without failures.

Benefits of a static balancing valve

- Fixed valve setting.
- The presence of such an opportunity, how to completely close the valve, with its subsequent reconfiguration.
- Easy in the installation, you can install in any position.
- The highest ability to pass the coolant.
- The setting can be conducted in diagrams that are in regulatory documents.
As we see the advantages of the static balancing valve are obvious, however, it is not all. The main advantage is, namely the valve can be used in drainage. To do this, it is enough to install nipple with the drainage function for measuring. This nipple is not included, it goes separately.

Installation and operation

- At the very beginning of work, the system must be thoroughly blown away and washed. It is necessary to remove solid particles that can damage the seal of a static balancing valve.
- It is impossible that external and internal efforts from the pipeline acted on the valve.
- the installation of the valve can be carried out in any position, however best option There will be the arms of the handle down.
- Static valve opens against the clock arrow.
- It is categorically impossible to use other levers.

Setting up valve

It is very important to properly configure the valve for its proper functioning. The setting is performed using the handle and two windows. To save the settings made, you need to remove the lid that is in the center of the handle to access the screw that is designed to adjust. As soon as the flow is set, you need to fix it until it stops. Then we insert back the lid. If necessary, you can partition this position for fixing.
Consumption that passes through reinforcement can be found using measuring instruments. It is necessary to make calculations at the following order:
1. Connect the flow meter.
2. Pick the desired units of measurement.
3. Take the desired valve brand.
4. Pick up the type and size.
5. Enter the current value.
6. Measure consumption.

Miscellaneous amount of heated coolant falling into radiators leads to uncontrolled air warming in rooms. Side branches heating system Even when installed circulating pump Can get less thermal energy than the main cycle. Static valves are designed for manual temperature control, pressure and coolant supply to radiators. They are produced in the form of valves of various designs.

Types of static valve

Manual pressure balancing / temperature is performed by increasing or decreasing flow cross section between the saddle and the spool. Depending on the model, the valve may have an adjusting core functioning on the principle of a hinge crane. Many manufacturers deliberately connect two functions in their products: balancing and shut-off valves. Static valves are made of chromed brass and cast iron; Differences in the classification - at the place of installation, the method of attachment, type and parameters of the working medium.

Hand balancing reinforcement selection

Static valves are chosen by maximum parameters bandwidth, adjustment accuracy and method of fastening to tubular endings of the heating system. There is balancing fittings for a thread or flange. Construction differences affect where the valve should be installed. This may be a feeding or reverse section of the heating system, bypass.

Characteristics of static valves

Manual balancing fittings is characterized by the diameter of the conditional passage, throughput, rated pressure, the presence / absence of measuring nipples. Knowing the features of the valves and taking into account the manufacturer's recommendations, you can fully implement their operational potential.

Features of manual balancing fittings

Static valves, depending on the model and manufacturer, are equipped with measuring and drainage nozzles, a diaphragm, indicator and the shutter position.

Application of static valves

Hand-type balancing fittings are installed in front of heating radiators in systems. autonomous heating. This is done to optimize the movement of the heated coolant, which increases the efficiency of the functioning of the heating system and reduces energy consumption.

Installation and installation

Static valves are established taking into account the manufacturer's recommendations and follow-up to compliance with the system launch algorithm. Depending on the type and model of balancing reinforcement, there are limitations at the minimum length of direct pipelines before and after the manual valve.

The operation of the heating system is often accompanied by an uneven distribution of the coolant along the contour and the connected devices. This can lead to pressure drops and temperatures that adversely affect the effectiveness of heating and can derive the equipment. Balancing valve is helped to prevent these consequences, various models Which is implemented by Forsterm.

Manual balancing valve: principle of operation and purpose

This device is a type of pipeline reinforcement and is used for the calculated distribution of the coolant along the contour and align its pressure and temperature. Regardless of which the design is a balancing valve, its principle is based on changing the capacity of the pipeline by increasing or decreasing the conduction section. This is achieved by the gradual movement of the spool relative to the input hole of the device, and therefore the device allows smooth adjustment.

Video, Balancing System Schemes

Through the use of the flow meter, the flow balancing operations are simplified, since the flow rate can be considered and configured at any moment, without resorting to the help of differential pressure gauges and reference graphs.

Regulator differential pressure Supports constant, on the prescribed value, the pressure difference that exists between the two points of the hydraulic circuit.

Autoflow devices are capable of automatically balanced the hydraulic circuit, ensuring the estimated consumption on each terminal. Even in the case of partial overlap of the contour due to the operation of the control valves, the costs in open circuts remain constant at nominal values. The system always provides the best comfort and provides the greatest energy saving.

Assortment of balancing valves for heating system

In the catalog you can pick up pipe fittings The following types:

• manual balancing valve - such a device is adjusted using the valve and operated in systems with constant pressure indicators, such as home heating and water supply;
• automatic balancing valve - such fittings equipped with electrical or electrical drives and is suitable for installation in systems with dynamically changing pressure requiring a quick and accurate response.

The catalog also presents various components that optimize and expand the functionality of the valves, in particular, flow stabilizers and drives.

The functionality of the available devices allows to significantly increase the efficiency of heating or water supply. Their use will extend the operational life of the equipment, reduce the noise in the plumbing and the likelihood of pressure jumps. In our catalog you can familiarize yourself with the detailed technical descriptionwhich accompanies each balancing valve for the heating system, and employees "Forsterm" will instruct in detail on the selection, installation and operation of this reinforcement.

The heating system needs periodic adjustment. The coolant should be evenly distributed over it, which means that the presence is required special equipmentwhich will help produce adjustment correctly. Such a device often acts as a balancing valve.

By hydraulic balancing, the coolant applies to all the sections of the heating scheme without exception.

Simple versions of systems involve adjusting the coolant consumption by selection optimal diameter Pipes around the perimeter.

Special washers also apply, the passage in which is designed for uninterrupted water flow, and uniform heating of the elements.

Each of these options was used in heating schemes Old sample. New method - Installation of a balancing valve, which is a conventional valve that regulates the amount of coolant feed.

Feature design

High-quality part includes reliable component elements:

• Durable brass body, which has threaded nozzles for connecting pipes. Inside the product there is a saddle in the form of a special vertical channel.
• Adjusting spindle. The working part is represented by a cone, which is screwed into the saddle. As a result of the use of the spindle, the coolant stream overlaps.
• Rubber sealing rings.
• Cap, made, as a rule, from plastic. Metal options are also found.

A distinctive feature of the device is the presence of two special fittings.

They are responsible for the following functions:

1. Determine the pressure inside the system both before and after the valve.
2. Connect the capillary type tube.

Each of the fittings measures the pressure, and if the values \u200b\u200bdrop on the regulating mechanism are detected, water consumption is calculated.

Operating principle

Balancing valves are designed to achieve maximum returns to all heating elements Systems, as well as at any time, make it adjustment.
