The Flow Resistance of Shut-off Valve
The valve stem axis of the shut-off valve is vertical to the valve seat sealing surface. The opening and closing strokes of the valve stem are relatively short. And there’s a very reliable shut-off action, which makes this kind of valve very suitable for shutting-off, regulating, and throttling of the medium. Once the valve flap […]
Read moreThe Sealing Performance of Stainless Steel Ball Valve
There are the reduced diameter and non-reduced diameter structures for sanitary ball valve. Regardless of the structure, the flow resistance coefficient of the ball valve is relatively small. In particular, for the so-called full-flow type, also known as non-reduced diameter ball valve, because its channel diameter is equal to the inner diameter of the pipe, […]
Read moreThe Uses and Features of Blower Safety Valve
What is the Most Common Use of a Blower Safety Valve? The blower safety valve is used to protect the blower and equipment. When the pressure in the blower and equipment is abnormally raised to a certain value (the opening pressure of the safety valve), the safety valve can automatically open and discharge the medium […]
Read moreIntroduction of Upper Sealing Structure of Shut-off Valve
The shut-off valve has a simple structure. It can be opened or shut off through the mechanism of the valve stem rotation and lifting. And the sealing and upper sealing functions of the valve can be ensured. Due to the special movement mechanism of this structure, it will cause extremely unfavorable consequences to the upper […]
Read moreThe Use of Pilot Type Safety Valve
Pilot type safety valve converts the direct effect of the spring into the indirect effect of the guide valve, which improves the action’s sensitivity. And the main valve is sleeve piston type. Double sealing sanitary valve seat structure ensures high action precision, good repeatability, quick seat returning, no leakage, the ability to discharge with high back […]
Read moreThe Proper Ways to Clean the Filth of Hydraulic Valve
Many users don’t have problems with the use of hydraulic valves. But they don’t have a clue about the subsequent maintenance and cleaning. Here is the introduction to the cleaning technology of hydraulic valves. How do you clean hydraulic valves? Note the following when we do the cleaning Filth of the Hydraulic Valve: 1. For […]
Read moreIntroduction of Knife-shaped Gate Valve
Knife-shaped gate valve has the advantages of simple and compact structure, reasonable design, light materials, reliable sealing, light and flexible operation, small size, smooth channel, small flow resistance, lightweight, easy installation, and easy disassembly. It completely solves the difficult problem of heavyweight, large flow resistance, large area, and difficult installation commonly found in the ordinary […]
Read moreBrief Introduction of Liquefied Gas Shut-off Valve
The opening and closing member of the liquefied gas shut-off valve is a plug-shaped valve flap. The sealing surface is flat or cone-shaped. The valve flap makes linear motion along the centerline of the fluid. The movement of the valve stem includes lifting rod type (the valve stem lifts while the hand wheel doesn’t lift) […]
Read moreThe Improvement on Sealing Structure of Shut-off Valve
The shut-off valve has a simple structure. It can open or shut off the valve and ensure the valve’s sealing and upper sealing function through the mechanism of the valve stem being able to both rotate and lift. Due to the special movement mechanism of this type of structure, it has adverse consequences on the […]
Read moreCommon Failures of Automatic Valves
Common Failures of Automatic Valves Failure number one: the valve is stuck. The reasons include: 1. The control channel is blocked by debris (the channel is small so it’s prone to blocking) 2. Due to rust, the piston is stuck at the highest position. Although it’s impacted at the upper part, it can’t move down, […]
