Q:Are rubber check valves and swing check valves the same type of valves?
Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H
Q:What is the reason that the check valve does not stop water?
1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.
Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?
Vertical lift check valves and lift horizontal check valves are different in structure, type, appearance, including installation.Vertical lift check valve, also known as vertical check valve;Lifting horizontal valve check valve, also known as horizontal check valve.Lift check valve: check valve sliding along the vertical centerline of valve body, lift check valve can only be installed on horizontal pipe,Disc can be used in high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve by the media force open, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect.Through lift check valve, the direction of inlet and outlet of medium is perpendicular to the direction of valve seat passage;Vertical lift check valve, the direction of its medium inlet and outlet passage is the same as that of valve seat passage, and its flow resistance is smaller than straight through.
Q:What is the difference between the check valve h64h-250 and the h61y-250?
According to JB/T308-2004 "valve type programming method"One is the swing check valve (4), and the sealing surface is Cr13 (H)One is the lift check valve (1), and the sealing surface is made of Y
Q:Check valve authentication information
CE (PED, 97/23/EC) ComplianceCE (pressure equipment, 97/23/ EC) certificationMany Check-All valves comply with pressure equipment instructions (PED, 97/23/EC). Our certificate number, CE62128, was issued by the British Industrial Standards Institute (BSI), and it is also the designated body of compliance assessment for our component H (full quality system).B16.34, Certification, ASME, B16.34 flanges, threaded and welded end connections, valves, certificationsPart of the valve size can be supplied in accordance with the B16.34 certificate.
Q:Can the swing check valve stand upright?
Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.
Q:Three forest electric water heater, hot water flow is small, check valve dripping problem?
You called the check valve is also called one-way valve, safety valve has non-return function, also known as relief valve, also can be said as a pressure reducing valve. About 7 kilograms of pressure will generally not Water Leakage, Water Leakage, because of the small water valve and is a function of the filter, open the inlet connecting, you will find a safety valve on the water inlet filter gasket, cleaning.There's no more than 100 in that thing. We're all dead. Send you one.You said that Sanlin manufacturers on this level? Too oftenThe safety valve must be fitted, or the tank will be under great pressure and the hot water will run into cold water.Relief valve function: release, check, filter
Q:Why is the water ring vacuum pump equipped with check valves?
The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
Q:Is the hdf41x 1.6Mpa a check valve?
Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution.
Q:What is the function of the small check valve on the deep well pump?
This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
