The function of High Pressure Hydrogenation Valve is to allow the medium to flow in one direction only and prevent the flow in the other direction. Usually, this High Pressure Hydrogenation Valve works automatically. Under the pressure of the fluid flowing in one direction, the Special Valve opens; when the fluid flows in the opposite direction, the fluid pressure and the self-closing Special Valve of the Special Valve act on the valve seat to cut off the flow.
High Pressure Hydrogenation Valve failure and troubleshooting methods
The failure of the High Pressure Hydrogenation Valve will directly affect the operation of the switching valve and the regulating valve. Common failures include the failure of the High Pressure Hydrogenation Valve to operate. The following aspects should be checked: (1) The High Pressure Hydrogenation Valve wiring head is loose or the wire head is detached. The High Pre
Appearance and working principle of Programmable Switch Butterfly Valve
The high-pressure chamber of the Programmable Switch Butterfly Valve is connected to the cylinder, and the low-pressure chamber is the gas outlet and leads to the use system. The indication of the high-pressure gauge is the pressure of the gas stored in the cylinder. The outlet pressure of the low-pressure gauge can be controlled by the adjusting screw. When using, first open
The relationship between the flow rate and the switch of the Programmable Switch Butterfly Valve
If it is used to control the flow rate, its flow characteristics are also closely related to the flow resistance of the piping. For example, if the valve diameter and form of the two pipelines are all the same, but the pipeline loss coefficient is different, the flow rate of the valve will also be very different. If the Programmable Switch Butterfly Valve is in a state of large t
Installation instructions for using programmable switching butterfly valves
1. Before installation, you must carefully check whether the valve's logo and certificate meet the usage requirements, and clean it after verification. Programmable Switch Butterfly Valve that are not installed and used should be stored in a dry room. Valves that have been kept for a long time should be cleaned regularly, dried and coated with anti-rust oil. Blind plates should be used at both ends of the valve to protect the flange sealing surfaces.
Learn about the installation of Programmable Switch Butterfly Valve
(1) Remove the protective covers on both sides of the flange end of the Programmable Switch Butterfly Valve, and flush and clean the valve with the valve fully open.

Troubleshooting method for internal leakage of Pressure Relief Valve
Pressure Relief Valve have been increasingly used in various industrial control systems due to their high control accuracy and convenient installation and debugging. However, during use, there are also some problems that bother on-site instrumentation personnel, namely the problem of valve internal leakage. Here we will discuss the common causes and solutions of internal leakage of Pressure Relief Valve, hoping to be of some help to the factory`s on-site maintenance personnel.
Structural features of Pressure Relief Valve
1. Leave a position for the valve handle to rotate. 2. Cannot be used as throttling. 3. Universal Valve with transmission mechanisms should be installed upright. The working principle of the Pressure Relief Valve is to unblock or block the valve by rotating the valve. The Universal Valve has a light switch, small size, can be made into a large diameter, reliable sealing,
Application of Pressure Relief Valve in textile production
In textile production, the drying method of sizing machines is to use drying cylinder heating. Its working principle is that the wet sizing yarn is in direct contact with the surface of the high-temperature metal drying cylinder. The surface of the drying cylinder obtains heat and transfers it to the surface of the sizing yarn, so that the moisture contained in the sizing yarn is continuously vaporized, the moisture regain rate of the sizing yarn is continuously reduced, and the surface of the sizing yarn is gradually formed. Serosa. A layer of condensed water formed on the inner surface
1. When the pneumatic actuator is connected to the circuit and system air source, air enters cylinder A (cylinder B) through pipe A or B to push the piston to move to one end, thereby driving the rotating shaft and ball core to rotate 90°. 2. The top of the pneumatic actuator is linked to the visual indicator. When the green sign points to the word "open", it indicates that the Steam Trap is open.
Analysis of operating torque of Needle Valve
When the opening of the Needle Valve is above 10%, the axial force of the Needle Valve, that is, the operating torque of the Needle Valve does not change much. When the opening of the Needle Valve is less than 10%, the pressure difference between the front and rear of the Needle Valve increases due to the throttling of the fluid. This pressure difference acts on the gate plate, so that the valve stem requires a larger axial force to drive the gate plate, so within this range, the operating torque of the Needle Valve changes relatively large. The operating torque required for a Needle Val
A brief introduction to the characteristics of Needle Valve
1. Small diameter Needle Valve bodies are all precision castings High-tech precision casting technology and equipment enable stainless steel castings to obtain a dense organizational structure. There are no casting defects such as "pores, looseness, and sand inclusions" at all. The appearance is neat and beautiful. The leakage rate index of the valve body is better than 10-10Pa.M3/S. Fully suitable for ultra-high vacuum working conditions.
How to extend the life of Plug Valve
1. Increase the opening and extend the service life When starting to use the Plug Valve, try to work at a wide opening, such as 80%. In this way, the erosion, wear and other damage caused by the initial impurities in the pipeline occurs in places other than the damaged part of the valve core. After the impurities in the pipeline are removed, the opening of the Universal Valve is adjusted to a slightly larger normal opening. , as the fluid damages the valve core and the flow rate increases, the arc polishing machine correspondingly reduces the opening, which continues to destroy an
How to protect Ball Valve from freezing
If you select and install a suitable Ball Valve, as long as steam passes through it, there will be no freezing problem. But if the steam is cut off, the steam condensate will form a vacuum in the heat exchanger or accompanying pipe. This prevents condensation from draining freely from the system before freezing occurs. Therefore, install a vacuum breaker between the equipment being discharged and the Ball Valve. If gravity discharge is not used from the Ball Valve to the return pipe, the Ball Valve and discharge line should be manually discharged or automatically discharged using a disch
