Ordering Process

HS941X electric piston regulator valve is the latest product developed by Shanghai Qigao Valve Manufacturing Co., Ltd. on the basis of digesting and absorbing foreign technology. It has many functions, such as flow control, decompression and voltage regulation, pressure relief and pressure control, vent and energy dissipation.

HS941X electric piston regulator valve has novel structure, advanced performance and reliable operation. It can be widely used in water conservancy and hydropower, metallurgy, petrochemical, water department, municipal, environmental protection and other industries.

purpose

Based on the advanced experience of Germany and Japan and the summary of domestic design, manufacture and practical experience, the electric regulator valve is developed according to the characteristics of fluid mechanics. It has been widely used in power plants, water diversion, water supply and other fields. The improved series of flow control valves are not only suitable for clean water, but also have good tolerance to natural rivers, lakes and light sewage. From the design structure and material selection, the problem of scaling, blocking and large driving device of flow control valve has been solved for many years.

Electric regulating and pressure regulating valve is mainly used in water network system with medium as water in water plant, power plant, water diversion project, etc. It can regulate medium flow, flow pattern and pressure of pipeline network. Characteristic of the electric regulator valve, the valve is superior to the traditional flow regulator valve because of its structural design and material selection so that it is not afraid of sewage blockage slideway, not afraid of scaling phenomenon, not easy to jam. The driving device is obviously reduced. The valve can automatically adjust the pre-set pipe medium parameters to keep constant in a certain precision, and the accuracy range can be adjusted. The valve has good cavitation resistance. The rib plate of the valve body wall has the function of the rectifier plate. It can disperse the flow of water and prevent cavitation. At the same time, the noise of the valve and the vibration of the piston are also reduced. The control system of the valve can adopt integrated electronic circuit, small size, good reliability, high sensitivity, easy installation and debugging. The total leakage is zero, which can be used as a globe valve. It is not necessary to set up other cut-off valves. If the control degree and accuracy requirements are not very high, the valve can be controlled by manual or ordinary electric form. It can be installed horizontally or vertically.

Product structure characteristics

The electric piston type regulating valve is composed of the front valve body, the back valve body, the valve stem, the guide and the sleeve. The guide made of stainless steel is fixed in the cavity of the back valve body, and spray holes are evenly distributed on the surface of the guide; the sleeve is connected with the valve stem on the guide sleeve, and the position of the sleeve is controlled by the external control parts to adjust the valve overflow area. The external control parts can be manually operated, electrically operated, pneumatic and hydraulic operated according to the working conditions.

1. Valve body

The valve body comprises a front valve body and a rear valve body, and an axial symmetrical flow passage is arranged in the rear valve body.

2. Deflector

Director is the key component of multi-function piston valve. There are many waist-shaped grooves on the wall. All waist-shaped grooves are arranged according to certain combination rules according to the working conditions and media conditions.

Working principle

The electric piston type flow regulating and regulating valve is guided by the deflector on the diverter. Water flows in from the outside of the diverter and flows through the jet holes on the diverter to form multiple streams of water, which produce collisions in the valve body cavity to achieve energy dissipation effect. The impact of cavitation and erosion on the valve body is effectively reduced and the service life of the valve is improved. The main sealing ring is located at the front of the guide, and the piston is guided on the whole stroke. When the piston is pushed through the main sealing ring to the full closed position, the differential pressure between the front and back of the valve forces the main sealing ring to close to the outer wall of the sleeve to achieve truncation. The piston moves back and forth in the guide through the guide rod. The valve rod is driven by the crank and the connecting rod. When the actuator drives the valve rod to rotate clockwise, the piston moves backward to open the valve. When the actuator drives the valve rod to rotate counterclockwise, the piston moves forward and closes the valve.

Main technical characteristics

Axial symmetrical flow passage: The valve body adopts axial symmetrical flow passage, which completely avoids unnecessary flow direction change, and makes the noise and turbulence trend significantly reduced.

Pressure Balance: Because the multi-function conical valve uses a pressure balance sleeve, the axial force of the operating sleeve has nothing to do with the pressure difference between the two ends of the valve, so the use of a smaller actuator can achieve the purpose of quick movement.

Good regulation effect: Nearly digital control, by changing the number of orifices to achieve the change of runner area, has a good linear regulation characteristics.

Electric multifunctional piston valve

The electric actuator is intelligent, with many functions such as stroke protection, torque protection, phase missing alarm and so on.
