Q:Check valve is 150, why not put 150 of the smoke pipe?
DN150 check valve, it is possible that the internal path is less than the required value of 5mm-10mm. Therefore, the 150 outer diameter of the smoke pipe is not up.
Q:Check valves - check valves - what's the difference between one-way valves?
Check valve. Check valve is the same, but the name is not the same. According to the customary name of the country. In fact, the same valve.
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:How can the lift vertical check valve be distinguished from the lift horizontal check valve?
1, vertical lift check valve should be installed on the vertical pipe. 2, lift type horizontal check valve should be installed in the horizontal pipe.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:How to use the check valve when the size of the pressure?
1, the use of check valve, the pressure level should be the size of the pipe corresponding to the pressure level.2, check valve and other valve class, the pressure levels for 0.6Mpa, 1Mpa, 1.6Mpa, 2.5mPA, 4mPA, 6 Mpa...... Wait。 If your pipe is between standard pressure, use a higher pressure grade. Such as: pipe pressure 1.8Mpa, the minimum choice of 2.5Mpa check valve.
Q:What does the check valve "H44Y-160" mean?
H check valve, 4 flange connection, 4 spiral structure, Y sealing hardfacing alloy. 160 nominal pressure 16MPa
Q:How to prevent the backflow valve of medium
Check valve operating principleCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).
Q:What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?
The first H is the meaning of the check valve (the first letter of the Chinese phonetic alphabet). The second H should be the meaning of "slow closing" (the first letter of the Chinese phonetic alphabet).
Q:What's the difference between a throttle valve and a check valve? Are they the same?
The check valve is directional, so it should be clear when installing. It is like a swinging door that opens in one direction or closes on the other. When the liquid flows towards the opening, the door opens, and when it is stopped, the self pressure of the liquid passing through the door closes automatically and acts as a hindrance to the flow of liquid.Throttle is simple, water switch is one of the throttle valve.
Q:The principle of the check valve
The function of the check valve is to allow the medium to flow in one direction only, and to prevent the flow in the opposite direction
