Working principle and installation of High Pressure Hydrogenation Valve
The High Pressure Hydrogenation Valve uses a spring-limited valve plate, which is determined by positive and negative pressure to exhale or inhale. There is also a gravity-type High Pressure Hydrogenation Valve, which is adjusted by gravity. When the air pressure in the container exceeds the heavy pressure, the valve opens to relieve pressure. Specific description: When the pressure in the storage tank is balanced with the atmospheric pressure, the High Pressure Hydrogenation Valve exhalation valve is closely matched with the exhalation outlet valve seat, and the inhalation valve is clos
Improvement of sealing structure and materials on High Pressure Hydrogenation Valve
The High Pressure Hydrogenation Valve has a simple structure. The valve can be opened or cut off by the principle of both rotation and lifting of the valve stem, and the sealing and upper sealing functions of the valve can be ensured. Due to the special movement principle of the structure, it also causes extremely unfavorable consequences for the force between the sealing pairs on the valve (forming both the required vertical pressure between the sealing pairs and the friction of relative sliding between the sealing pairs). Practice has shown that the upper seal of the valve is often ope

Its use mainly relies on the adjustment operation of current.
Analysis of corrosion occurring during use of Programmable Switch Butterfly Valve
The Programmable Switch Butterfly Valve appears to be corroded during use. After metallographic structure analysis, dyeing test, heat treatment test, SEM and other experimental analysis, it was found that the key factor in material corrosion is that the carbides along the grain boundaries in the material precipitate to form a chromium-depleted area, which causes the non-Programmable Switch Butterfly Valve to rust, The Programmable Switch Butterfly Valve made of CF8M has rusted during use. After normal heat treatment, the structure of austenitic stainless steel should be austenite at room

Solution to Steam Trap pressure problem
The cross-pressure problem of Steam Trap is not a common phenomenon, but it is also a possible failure problem. As users, we still need to have a good understanding of it and master the ability to analyze and solve its causes: Due to the rupture of the pipe network in the pipe section behind the Universal Valve, the valve at P1 is closed or repaired, and when the water pump in pump s
Steam Trap failure and troubleshooting methods
The failure of the Steam Trap will directly affect the action of the switching valve and the regulating valve. Common failures include the Steam Trap not operating, which should be checked from the following aspects: (1) If the connection head of the Steam Trap is loose or the thread ends fall off, the Steam Trap valve must not be powered, and the thread ends can be tightened. (2) If the Steam Trap coil
Working principle and structural characteristics of Needle Valve
Working principle of Needle Valve: The eccentric rotary regulating valve is a straight-through valve body structure with novel structure and low fluid resistance. The rotation center of the valve core is not concentric with the rotation axis, which can reduce the wear of the Universal Valve and extend the service life; after the valve core The bottom is equipped with a deflector wing, which is conducive to the stable flow of fluid and has excellent stability. At the same time, it also has the advantages of large flow rate and wide adjustable range, which is especially suitable for the co
Selection of Plug Valve structure type
1) Adjustment function ① The valve is required to operate smoothly; ② The small opening has good adjustment performance; ③ Select the required flow characteristics; ④ Meet the adjustable ratio; ⑤ Small resistance and large flow ratio (the ratio of the rated flow parameter of the valve to the nominal diameter); ⑥Adjust the speed. 2) Leakage amount and cut-off pressure dif
How to test and install pipeline fully welded Ball Valve
Fully welded Ball Valve for pipelines should undergo a pressure test before installation to ensure the tightness and safety of the valve itself. 1. Fully welded Ball Valve test (1) Strength test: The strength test uses water as the medium; high-pressure caps are welded on the sleeves on both sides of the valve. After opening the valve to the 45°C position, inject wa
How Ball Valve drive industrial transformation
As a new type of valve in recent years, Ball Valve have defeated some domestic valves in the fiercely competitive domestic market by virtue of some of their unique structural characteristics and quickly seized market opportunities. However, with the development of industry in the past two years, especially in 2016, my country has paid special attention to the transformation of traditional industrialization. So at this time, can the manufacturers of forged steel high-pressure Ball Valve, as traditional valves, drive the transformation of the industry?
Main structural features and operation of Ball Valve
The Ball Valve adopts the design of fixed valve core (shaft-supported type) and movable sealing seat on the upper and lower valve stems. The job is more stable. It has automatic compensation function, large shearing force and self-cleaning function when rotating without gap between the two-way sealing valve seats. It is especially suitable for switching on and off imperial fibers, suspensions and viscous media with tiny solid particles. Ball Valve products can be widely used in automated control systems in industrial sectors such as papermaking, petrochemicals, chemicals, metallurgy, ele
The Ball Valve is an automatic pressure relief protection device opened by inlet static pressure. It is one of the most important safety accessories for pressure vessels. Its function is: when the pressure in the container exceeds a certain value, it will automatically open based on the pressure of the medium itself. The valve quickly discharges a certain amount of media. When the pressure in the container drops to the allowable value, the valve automatically closes, so that the pressure in the container is always lower than the upper limit of the allowable pressure, automatically preven
Precautions for correct installation of Ball Valve
1. Read the product manual carefully before installation, check whether the product meets the usage requirements, remember the installation points, and make preparations. 2. Pay attention to the cleanliness of the medium. If the medium is mixed with dirt, impurities, etc. that will hinder the normal operation of the Ball Valve, a filter valve with a mesh of ≥60 mesh should be installed in the pipeline
Several details that should be paid attention to when installing the Ball Valve
The self-operated pressure steam Universal Valve is a type of self-operated Universal Valve.
