Q: The working principle and structure description of the mute check valve: Slow closing check valve and check valve or check valve, its role is to prevent the media back in the pipeline, its working principle is as follows: first, the role of principle: moving through the cylinder plug on the valve flap, assist the rapid opening and closing to the sealing surface two, structure 1 structural forms: swing type 2 single disc drive mode: 3 butt welding connection: open and closed by a pneumatic device to control the butt welding of the 4 valves, speeding up the valve opening and closing speed.

Q: Assembling process of clip type check valve: Among them, the stainless steel clip check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements.

Q: Check valve H15B-16 DN25 is that product?: Screw swing multi valve check - nominal pressure 1.6Mpa, product caliber 25mmOur company has production!

Q: The role of the clip lift check valve: Among them, the internal check valve, butterfly check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small

Q: Today, I saw the name of the fire check valve on the drawing of a project. Who knows what this is? I haven't met before: Fire check valve, suitable for installation in the kitchen of the air inlet is connected with the common flue, smoke lampblack machine, lampblack and other indoor air discharge to the roof, can prevent the flue gas in the flue flow, and when the building fire, the fire spread to the common flue, the check valve will automatically shut down, stop to fire you spread the rescue of property and escape more time for you, protect your property and life safety. The fireproof device is sensitive and reliable, and is favorable for environmental protection and improving the fire safety level of the house.

Q: What can I do with the lift check valve?: Standard light valve for you to answer, lift check valve is to rely on the media itself flow and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve.

Q: Ball shaped sewage check valve pictures and working principle of the structure.: 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.

Q: Is the flue check valve the same as the flue check valve? What's the difference?: The flue check valve is not the same as the flue check valve;Flue check valve: a valve that is used at the joint of the hood, flue pipe and flue. Mainly to prevent the role of soot intrusion. The smoke in the apartment building is a public flue, and sometimes the food is always wafted from upstairs to downstairs when cooking, usually from the flue. This check valve can have a certain extent to prevent soot from the role of intrusion, but after all, it is difficult to completely sealed, so the food can not completely prevent the taste of isolation.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.

Q: Is it necessary to install a check valve in the piston refrigeration compressor?: To solve this problem, we first need to know the working cycle of the piston compressor:1, compression process, suction valve closed, refrigerant gas in the cylinder from low pressure to high pressure process;2 the exhaust process, compression end, from the cylinder through the exhaust valve to exhaust pipe process;3, expansion process, exhaust end, exhaust valve closed, the piston from the bottom of the cylinder moving to the top of the cylinder process;4 suction process, suction valve opens, low-pressure refrigerant gas inhalation process of the cylinder;From the above piston engines don't seem to need what steps to open check valve. Because the suction valve and exhaust valve on the cylinder are constantly switching each other, the piston machine continues to inhale and exhaust the process. If only from the piston machine, there is no need to install a check valve.But to consider the whole refrigeration system, rather than a simple piston compressor, when the piston of more than 2 units must be horizontal pipeline in a single compressor exhaust pipe to the exhaust duct installed on the check valve and pipe installation is about

Q: What is the difference between globe and check valves?: 1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed.2., the cut-off valve can be used to regulate flow, can be closed, can be closed.
