Q: The working principle and structure description of the mute check valve: 1, when the medium according to the provisions of the direction of flow, the valve by the media force, is open; the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.2, the body and valve sealing surface using stainless steel surfacing.3, the length of the valve according to the provisions of GB12221-1989, flange connection size according to the provisions of JB/T79-1994.

Q: Can the check valve be horizontally installed?: Lift check valve can be divided into straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.

Q: Can the check valve be used on the steam pipe?: The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.

Q: What is the structure of the check valve of the screw air compressor?: Work process: air pre filter, and then through the air filter and the air inlet controller into the mixing chamber and the compression screw lubricating oil, continuous linear by asymmetric rotor two, compression. The compressed oil and gas mixture enters the tank and the separation system for three levels of separation (centrifugal, self weight, and fine separation). The separated compressed air is discharged after the cooler is cooled, and a reliable pressure switch system controls the exhaust pressure. When the machine is running, the screw compressor run oil system by pressure difference automatic circulation, without pump. When starting, the minimum pressure valve is closed to ensure the minimum pressure required for the lubrication oil circulation. In addition to lubrication, the oil also acts as sealing, cooling and reducing noise. High efficiency oil and gas separator and high efficiency cooler ensure high quality compressed air.

Q: Why can't the check valve on the air pipe be used when the wind speed is less than 8 meters?: First of all, you must understand the working principle of the check valve, indeed, as you said, you can adjust the position of the hammer by adjusting the position of the drop hammer.If you are in their own design and production, consider the thickness of the blade, drop hammer size, weight, and other parameters considered.Hope to be of help to you!

Q: The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work: 1. Do you have ink in the ink cartridge? If not, you can't hit it;2, the ink box installation is in place, let the printer self check to see whether the instructions are normal;3, everything is normal, "maintenance" in the print head, not, deep cleaning;Generally normal, no, that might be a cup, change cartridgesIn addition, the check valve must be opened when printing, the cartridge is not placed high, and so on after processing

Q: The difference between slow closed valve and open the valve: The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).

Q: Check valve h44h-25p what does that mean?: H- stainless steel4- flange connection4- rotary single structure check valveH sealing material is Cr13 stainless steel25- pressure 2.50MPAP-18-8 stainless steelH44h-25p= stainless steel flange connection, swing type single check valve pressure 2.50MPA valve body, material 18-8 stainless steel

Q: Does the check valve of the flue of the range hood work?: 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. According to everyone's reaction and market similar products sold well, smoke hood comes with soot hood flue check valve basically does not work.The picture of the check valve of the flue of the range hood is as follows:

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

We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
