The structure of the piston type electric flow and pressure regulating valve is: the valve body of the piston type electric flow and pressure regulating valve is divided into inner and outer layers, and the medium flows in the valve chamber between the inner and outer layers of the valve body. When the valve is running, the electric actuator receives a standard signal for action and drives the valve shaft to rotate through a gearbox. The valve shaft, through a crank mechanism, drives the valve plug in the valve chamber to move forward and backward along the pipeline axis, changing the flow channel area, and achieving the purpose of flow regulation and pressure regulation.

5The pressure regulating and flow regulating valve is the latest type of control valve, which can adjust or control flow without any operational restrictions. The pressure regulating valve has two types of structures: multi orifice and fan ring. Water is sprayed out through each orifice or fan ring and collides with each other in the center of the pipeline, causing complete disappearance of velocity energy. By adjusting the opening of the piston, the functions of reducing pressure, regulating flow, and effectively eliminating noise, vibration, etc. can be achieved.
Technical parameters:
1. Valve body: ductile iron QT450
2. Piston: stainless steel 304
3. Crankshaft, bolt: stainless steel 2Cr13
4. Outlet component liner and valve seat ring: stainless steel 304
5. Guide rail: stainless steel 304
6. Sealing ring: EPDM
7. Corrosion prevention: Static electricity powder spraying of blue epoxy resin inside and outside the valve body
The flow and pressure regulating valve has three functions: to regulate flow, to regulate pressure, and to cut off medium. The valve that integrates these three functions replaces gate and butterfly valves, saving nominal cost and installation space.
Mainly used in pipeline systems with water as the medium in water plants, power plants, water diversion projects, etc., it plays a role in regulating the flow rate and flow pattern of pipeline media, as well as regulating the pressure of the pipeline network.
Characteristics of flow and pressure regulating valve:
It is because of its structural design and material selection that it is not afraid of sewage blocking the slide, scaling, and is not easily blocked. The driving device is significantly reduced.
This valve can automatically adjust the pre-set pipeline medium parameter values to maintain a constant accuracy within a certain range, and the accuracy range can also be adjusted.
This valve has good resistance to cavitation, and the rib plate on the inner wall of the valve body also serves as a rectification plate, which can disperse water flow and prevent cavitation.
At the same time, it also reduces the noise of the valve and the vibration of the piston. The control system of this valve can adopt integrated electronic circuits, with small size, good reliability, high sensitivity, and convenient installation and debugging. The fully closed leakage is zero and can be used as a shut-off valve.
No need to install other shut-off valves. If the control level and accuracy requirements are not very high, the control of the valve can be manual or ordinary electric form. It can be installed horizontally or vertically.
The improved flow control valve of this series is not only applicable to clean water, but also has good tolerance to natural Rivers and Lakes water and light sewage.
The design structure and material selection have solved the problems of scaling, jamming, and large driving device of flow control valves over the years.
Purpose:
A new multifunctional valve suitable for urban water supply, industrial water supply, mine water supply, power plants, water diversion engineering and other pipeline network systems. It can replace shut-off valves, pressure regulating valves, and flow regulating valves (one valve replaces multiple valves) at the same time, playing a role in regulating flow, dissipating energy and emptying, as well as reducing pressure and regulating pressure. It has superior regulation and control functions for high pressure and large pressure difference conditions, and has the characteristics of energy dissipation, noise reduction, vibration reduction, and cavitation prevention. It can effectively improve the safety and reliability of the system and meet the requirements of system automation control.

Summary: The direct acting self operated pressure (differential pressure) regulating valve (V230 self operated pressure regulating valve) is composed of valve body,valve seat,valve core and other parts.It is an energy-saving product that can automatically adjust the pressure only by the pressure change of the regulated medium without external energy.It can be used for pressure control of non corrosive (maximum temperature 350 ℃) liquid,gas,steam and other media It is widely used in petroleum,chemical industry,metallurgy,light industry and other industrial sectors as well as urban heating and heating system.
Introduction: ZFQ-1 explosion-proof fire-proof breathing valve produced by our company is a relatively new product in China. It is a new product with flame arrester and breathing valve. Its new structure is the first in China. It is a necessary safety equipment for petrochemical storage tank. Its biggest advantages are good fire resistance, stable suction performance, simple structure, light weight and convenient maintenance. The product is suitable for storage of class a oil with flash point lower than 28 ℃ and class B oil with flash point lower than 60 ℃, such as gasoline, kerosene, diesel oil, crude oil, toluene, ethanol, aromatics, sulfur and other media tanks. It works normally in the temperature environment of -35 ℃ -60 ℃.
ZMBQ pneumatic film cutting valve adopts top guide structure, with multi spring actuator.It has the advantages of compact structure, light weight, sensitive action, S-streamline fluid channel, small pressure drop loss, large valve capacity, convenient disassembly and assembly, etc.
Overview of ZX pneumatic diaphragm three way control valve: ZX new series pneumatic diaphragm three-way control valve adopts cylindrical thin-wall window valve core guide,which is different from the bushing guide of plunger valve core.Equipped with multi spring actuator.ZX type pneumatic diaphragm control valve has the advantages of simple structure,light weight,small volume and convenient disassembly.Widely used in accurate control of gas,liquid and other media,process parameters such as pressure,flow,temperature,liquid level to maintain a given value.The utility model is suitable for the occasions where one fluid flows out in two paths through the three-way valve or two fluids are combined into one fluid through the three-way valve. This series of products have two kinds of three-way confluence (ZXQ) and three-way shunt (ZXX). The nominal pressure rating is 1.6, 4.0 and 6.4Mpa, and the diameter range of valve body is DN25-200.

Product introduction: ZZY type self operated pressure regulating valve does not need additional energy. It uses the self energy of the regulated medium and the power source to introduce the actuator to control the position of the valve core, and changes the pressure difference and flow at both ends to stabilize the pressure in front of (or behind) the valve. It has the advantages of sensitive action, good sealing, low power of pressure set point wave and so on. It is widely used in the automatic control of pressure reduction and pressure stabilization of gas, liquid and steam medium.
