Analysis of opening action characteristics of Globe Valve
Globe Valve are divided into full-lift type and micro-lift type according to the different opening heights of the valve disc. They rely on the elastic pressure of the spring to lock the valve's valve flap or plunger and other seals. Once the pressure of the pressure vessel is abnormal, a Globe Valve will occur. The high pressure will overcome the spring pressure of the Globe Valve, so the locking device is pushed open, forming a pressure relief channel to release the high pressure. The full-lift type has a large discharge capacity and good resilience, and is suitable for liquid and gas m
What are the methods for selecting Gate Valve?
A Gate Valve is an automatic pressure relief device used on pressurized equipment, containers or pipelines. When the pressure in the protected system rises above the allowable value, the valve automatically opens and discharges part of the excess medium to prevent the system pressure from continuing to rise. When the system pressure drops to a certain specified value, the valve can automatically close again, thereby ensuring The system operates normally. How to correctly select Gate Valve is directly related to the economic benefits of the user and the safety of operators and equipment.
The development prospects of Gate Valve in petrochemical and nuclear power industries
More and more industrial applications have new requirements for Gate Valve products, and the quality and technical requirements for Gate Valve are getting higher and higher. With the development of my country's Gate Valve industry, the varieties and specifications of Gate Valve are also increasing, and Gate Valve are used in more and more industries, such as the petrochemical industry, oil refining industry, nuclear power industry, etc. They are widely used.
Application range of Universal Valve
Gate Valve is a safety device currently widely used in hydraulic power systems and hydraulic equipment. It can also be used as a pressure limiting device. It is a special valve. It is different from traditional valves. Traditional valves are powered by mechanical metal springs and can only limit For medium and low pressures, when the pressure limit exceeds 10Mpa, only a larger volume boosting design can be made. Therefore, traditional valves must be bulky and bulky when used to limit the pressure of high-pressure and ultra-high-pressure hydraulic power systems and hydraulic equipment. Co
Adjustment of Gate Valve opening pressure
It is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium outside the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. In order to ensure that the Gate Valve can fully play its protective role in pressure vessels and pipelines, users should understand the relevant knowledge of Gate Valve opening pressure adjustment.
Briefly describe the installation points of Gate Valve
For the installation of Gate Valve, the first thing to note is that before installing the Universal Valve, the sealing performance must be tested.

During the installation process, the first premise is that for all components of the Universal Valve, everyo
Gate Valve discharge and seat back pressure adjustment
① To adjust the valve discharge pressure and reseating pressure, an action test must be carried out with the valve reaching the full opening height. Therefore, it can only be carried out on a large-capacity test device or after the Gate Valve is installed on the protected equipment. The adjustment method varies depending on the valve structure. ②For the structure with recoi

Faults encountered during operation of Gate Valve
1. Gate Valve leakage For equipment operating under pressure, leakage in excess of allowable levels occurs between the Gate Valve and the sealing valve seat. Cause: Dirt between the valve and valve seat sealing surfaces. When using a poppet valve, put the dirt and damage the sealing surface when the wrench is opened. Repair according to grinding or turning grinding method after a certain degree of damage; bend, tilt or tilt stem of lever and fulcrum, spool and valve position. The Gate Valve needs to be reinstalled or replaced because the spring elasticity has decreased or lost ela
Use the resulting suction effect to reduce the pressure above the Universal Valve
Gate Valve, when the pressure in the protected system rises, an additional force is generated on the sensing element, causing the element to move and open a gap in the Gate Valve channel, and the medium is discharged through the gap. The discharge capacity of the Gate Valve and the service life of its parts , related to the dynamic stability of the Gate Valve operation. The vibration of the Universal Valve will reduce the channel cross-sectional area and discharge capacity of the Gate Valve, and the collision of the Universal Valve with the valve seat and the opening height limiter will
Working pressure effect of Check Valve device
The cause of sudden excessive silo pressure or excessive pump pressure must be addressed immediately. Efficient and reliable equipment pressure Check Valve are a must for silo systems. When the pressure value is within the preset range, the coil spring keeps the cover closed. The three outer Check Valve springs keep the outer ring bonnet closed until the silo pressure is less than the spring force. When t
What are the requirements for Check Valve installed on thermal oil systems?
As one of the most widely used equipment in the industry, the thermal oil furnace is a pressure vessel. Its safe use is related to the safety of people's lives and property. Therefore, the last fuse of the thermal oil furnace = Check Valve and Universal Valve play a role Therefore, the installation of Check Valve and Universal Valve on thermal oil furnaces must comply with the following technical requirements:
What are the key points in the installation of Check Valve and their pipeline layout design?
(1) Check Valve on equipment or pipelines should generally be installed upright. However, Check Valve installed on liquid pipelines, heat exchangers or containers, etc., can be installed horizontally in places where the pressure may rise due to thermal expansion after the valve is closed; (2) The Check Valve should be installed as close as possible to the protected equipment or pip
Precautions when using Check Valve
Check Valve is a special device for pressure relief, which plays an important role in protecting accessories. Check Valve are generally installed directly on special equipment.

What is a Check Valve? It is necessary to master the basic knowledge
The Check Valve is a forced-sealing Universal Valve. When the Universal Valve is closed, pressure must be applied to the valve disc to forcefully prevent leakage on the sealing surface. When the medium enters the Universal Valve from under the valve, the resistance overcome by the operating force is the thrust generated by the wear force of the valve and gasket and the medium pressure, and the force to close the Universal Valve is greater than the force to open the Universal Valve, so the diameter of the valve stem larger. Otherwise, the top of the valve stem will bend. After the emergen
