This valve is installed in pipeline system as a medium against-flow protecting equipment.
- Q:How to install the check valve?
- Mounting position of check valve:Installed in the cut-off valve (solenoid valve, pneumatic valve, etc.), to prevent the back of the valve medium, the formation of back pressure or water hammer, affecting the normal use of the front valve.Check valve installed in the pipe bend elbow or vertical direction of the drop is larger, but also to prevent water hammer impact on the pipeline and damage.
- Q:The difference between swing check valve and lift check valve
- Swing check valve, swing check the valve to the disc valve seat around the channel axis for rotation, because the valve channel into a streamlined, flow resistance than the small valve lift check, suitable for large caliber occasions in low flow and no flow frequently change, but should not be used for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact.
- Q:What kind of valve does the check valve belong to?
- 1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve
- Q:Fire hood fire check valve okay?
- Lampblack machine flue check valve is generally installed in the hood outlet check valve, the valve has two blades, a reset spring, exhaust hood leaf was blown open, lampblack machine stop when the blade is spring pressed into the closed state, now is basically take lampblack machine the check valve check valve, but the general tightness is not very good, open the hood can be seen around the gap.
- Q:Is it necessary to install a check valve for household well pumping?
- Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
- Q:What is the HC41X-16Q model of the optical valve? What is its main function?
- The HC41X-16Q check valve for the light valve is a flanged silent check valve.HC41X-16Q flanged check valve features:An acoustic check valve whose structural characteristics allow only medium to flow in one direction and prevent flow in the direction.
- Q:Why is the check valve necessary? Why should it be checked back?
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.Check valve installed in the pipeline system, the main role is to prevent media backflow, check valve is a kind of pressure on the media to open and close the automatic valve. The clip type check valve applies to nominal pressure PN1.0MPa~42.0MPa and Class150~25000; nominal diameter DN15~1200mm and NPS1/2~48; work temperature -196~540 degrees of various pipelines, used to prevent medium flow back. By choosing different materials, it can be applied to many mediums such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
- Q:Installation position of household water meter check valve
- It should be about 15 times before the table, about 300mm DN20.
- Q:What is the function of the check valve?
- The function of the check valve is to prevent the medium from flowing back! Check valves, which are commonly known as check valves! Backflow of medium will cause the reverse of pump impeller, which may lead to the burnout of pump! Pumps used in industry are expensive nowadays! Ha-ha！ The check valve just protects the pump and piping!
- Q:The principle of the check valve
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
