Q:What's the difference between the h76x check valve h77x?
Check JB/T308-2004 "valve type programming method"The first number 7 is the clip typeThe 6 is a double valve swing structure7 butterfly check valveLook at the JB/T8937-2010 "clip on check valve"That's clear
Q:Is there a check valve with a relief valve above?
Over the excess pressure discharge, maintain protection of pipeline system valve. For reference!
Q:Should the kitchen check be mounted on the wall or on the hood?
Buy their own check valve is generally in the wall of the hole, the hood of the smoke machine, usually with a check valve.
Q:Which type of check valve should be selected for vertical pipes?
The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited
Q:Check valve 1 inches DN25 what do you mean?
Crown valve pressFirst, an inch equals DN25That is, fixed values to estimate how large a pipeline isOne inch of check valve is mostly copper check valveThe price of I should be around 25 yuan
Q:Pump adapter need check valve?
Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
Q:What is the function of the check valve in the pipeline?
Check valve, also known as one-way valve or check valve, refers to rely on the media itself flow 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.Effect:The function is to prevent backflow of medium in the pipeline. Pump water off the bottom valve check valve also belongs to class. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.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: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:Do you still need to check valve fittings for solar water heater installation?
Need, the solenoid valve automatically control itself has the function of manual water valve was the installation of the installation, but now a lot of pressure to see you still go not installed, they save cost, but will give users the trouble
Q:What is the function of the small check valve on the deep well pump?
Frequency conversion and it does not matter, the inverter is to speed down, so that the pump has a suitable flow and lift. This valve can not go.
