Electric valves in automation systems. FEATURES OF USE OF THE MANUFACTURE MANUFACTURE WATER VALVE VALVE OF HIGH PRESSURE PRESSURE POLUMATION

The control valve or the valve serves for continuous and discrete flow control, temperature and pressure in heating systems, hot and cold water supply, gas pipelines and oil pipelines, chemical industry. The principle of operation is based on changing the flow of the working medium using the throttle node.

The control valve changes the water supply, gas or other substance by the control device signal: controller, thermostat, etc. In modern industries, it enters the automation system, which allows you to control the level of consumption, temperature and pressure remotely.

We offer products of manufacturers "Asta", ADCA and Danfoss. Pipe fittings passes the test before entering the market and has quality certificates.

Types of valves

You can buy control valves that differ in the direction and number of flows of the working medium.

Passing valves have two nozzles - input and output - and installed on direct sections in pipelines.

Angular valves Change the direction of flow of the working medium by 90 degrees.

Three-way valves Called mixing. They are equipped with three nozzles (one input, two output) for connecting to the pipeline and are used to mix or separate 2 types of working medium.

You can buy regulating valves that differ according to the principle of operation: saddle, swivel. The first provide better control, less leakage, as well as capable of working with high pressure drops, high operating environmental parameters.

Also, the valves differ in the type of control (electric, hydraulic, electromagnetic, pneumatic), the method of attaching to the pipeline (flange, adhesive, coupling, fitting and welded for the valves of steel), by material.

Complexity engineering systems It turns out every year, the requirements for their energy efficiency, reliability, security, which dictates the use of modern pipe fittings, primarily regulating.

In this article, we will consider the main types of regulatory reinforcements that play an important role in solving the above tasks, as well as we will analyze some of the features of regulating valves delivered by the ADL, with PS-Automation (Germany) electric drives.

Regulating pipe fittings direct actionAs you know, to regulate the flow parameters of the working medium on a specific area. technological system or pipeline uses the energy of the same environment. Thanks to which the advantages of this type of reinforcement are: independence from external energy sources, control accuracy, as well as reliability. However, there is a disadvantage that often complicates and limits the use of direct operational regulators is the lack of flexibility. In other words, each knob is intended for use in a very narrow range of system parameters. For example, if we use a direct valve pressure regulator to regulate the output pressure of 5 bar, then to change the setting, for example, on 10 bar (all other parameters are unchanged), we will most likely need a completely different valve.

The following types of direct valves are found:

• reduction valves (pressure regulators "after themselves"), designed to maintain the continuous output pressure, regardless of changes in the input pressure or consumption;
• bypass valves (pressure regulators "to ourselves"), ensuring the maintenance of permanent pressure in front of the valve due to the rest of the part of the medium;
• pressure drop regulators, which are serving to maintain a constant pressure drop between two specified system points;
• special regulators (follow-up pressure regulators, Drazhelical impact dampers, etc.)

The regulatory fittings of the indirect action, on the contrary, uses external energy, such as electricity (electric drive), compressed gas energy (pneumatic reception), etc. The control signal for such regulators is also external. The signal comes from a logic device directly implemented by the control algorithm in the system. Thus, the regulatory fitness of indirect action ensures that the frequency is so necessary. For example, to regulate different pressure values \u200b\u200bor even to regulate other parameters, in some cases the same control valve can be used. Of course, systems that use indirect control regulators, much more complicated systems using direct operation regulators, which often adversely affects the regulatory speed, and in reliability indicators. However, modern electric drives allow us to eliminate the shortcomings. Such electric drives include, in particular, the drives of the production of PS-Automation GmbH (Germany), exclusively supplied to the Russian market by Adl.

So, linear electric drives are used to control regulating valves. Consider a little more details of the features of linear electric drives of the PSL series and PSL-AMS production of PS-Automation (Germany).

PSL series electric drives are designed according to a modular principle, which makes it possible to obtain maximum functionality with minimal costs. PSL actuators meet all the requirements for regulatory reinforcement: accurate positioning, strength, reliability and durability, even at high loads. The basis is a standard drive with a triplicate control and a necessary set of protection functions. In this case, the actuation characteristics can vary greatly depending on the installation of additional options. For example, the installation on the drive fee and potentiometer board allows the drive to be controlled by an analog signal (for example, 4 ... 20 mA, 2-10 V, etc.). In accordance with the tasks of the customer, the company's specialists ADL modify the electric drives of regulating valves, produce the necessary settings and testing. An important advantage is that the functionality of the drive can be changed after it is delivered and even installation in the system. Most actuator options can be purchased separately, among which:

• positioner with an acurative output signal;
• potentiometer;
• signal converter position;
• additional end telle off;
• heating resistor, etc.

To increase the reliability of the system, the PSL electric drives are completed with the following protection functions:

• automatic shutdown of the drive when the extreme position is reached;
• automatic shutdown of the drive when the maximum effort is reached;
• automatic shutdown of the drive at the risk of overheating windings of the engine;
• the ability to determine the positioning of the onset during the breakage of the power supply or control network; Moreover, this position (normal-open, normal-closed, current) can be changed directly on the pipeline using a switter switch.
• manual dubler.

Intelligent Linear PSL-AMS series have been improved electronic circuits On the basis of a microprocessor with a memory card, which ensures reliability and accuracy of management, as well as easy commissioning and easy setting.

The electrical current control and voltage control functions allow you to adjust the operation of the drive under the specific conditions of the system. So, through special communication software PSCs (comes in standard equipment) You can specify various drive parameters, corrective data, diagnose and much more.

Intelligent PSL-AMS series also have a number of additional options, such as the local control function on the housing, which allows you to set the drive operation at the installation site, as well as block access to its control, the integrated process PID controller monitoring and monitoring the specified parameters Work with the ability to program any non-standard drive behavior, intelligent management protocols (HART, Ethernet, Bluetooth, etc.), etc.

All of the above-mentioned series of linear electric drives have an IP65 or IP67 protection class and can be manufactured in a metal case.

PS-Automation electric drives are successfully used by Adl for a complete set of regulating valves of their own and European industries. The nomenclature of regulating valves is represented by two-way positive (both balanced and unbalanced design) and three-way valves in the diameter range from DN 15 to 300 mm, pressures from PN 16 to 40 bar, for the temperature of up to 300 ° C.

It is worth it to note that the installation of the electric drive to the regulating valve, its setting and testing is carried out at the production complex of our company, which guarantees performance, the minimum delivery time, and also allows you to manufacture a special execution of the regulating valve under the requirements of a particular system.
