Ha-ha！ The check valve just protects the pump and piping!

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: Should the pressure gauge be mounted before or after the check valve at the back of the pump?: It should be the valve behind the exit because it can be replaced easily if damaged

Q: What is the function of the stop valve and check valve installed on the water supply pipe?: The cut-off valve is a common valves, can also be used for throttling, mainly used to connect or disconnect the line of medium, generally not for regulating flows.

Q: Why is the check valve necessary? Why should it be checked back?: Check valve, also known as one-way valve, is designed to prevent liquid, gas and other substances backflow design valve.

Q: How much is the 6 point check valve for the water pipe at home?: 1, home hose with 6 points of the water pipe, check valve, copper 20-40 yuan.2, check valve refers to rely on the flow of the media itself 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. 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: Can the check valves fit two in one tube? One up, the other down: A water pipe is used for launching, and the two check valves that you install are reverse, and the water is blocked by one of the check valves on either side

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: How can the PPR pipe be connected to the check valve?: 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: What type of check valve should be installed before the suction pump?: second body cover seal welded forged steel check valve, connected by this form of valve, the valve body and the valve cover are connected by screw, all welded seal, the advantage of no leakage.
