- Q:What type of check valve should be installed before the suction pump?
- Self priming pumps are equipped with rotary, rotary or automatic type check valves.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. Forged steel check valves two body cover to connect the design form: the first is the body cover bolt connection forged steel valve, connected by this form of valve, the valve body and the valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance;
- 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:Type meaning of check valve
- This is a standard set, the landlord can see the standard: JB/T 308-2004H = check valve7 = clip type (connection mode)6 = double plate (structural form)After hundreds of H = 13Cr, sealing surface, J = rubber sealing surface
- Q:The working principle of the vacuum check valve
- The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.
- Q:My hood inside outside blow valve pops ringing
- Please take the pipe at the hood of the range hood for 15 cm or more, and then blow the wind. Note that the installation of fixed, do not affect the valve sag.
- Q:How can the fast closing noise check valve prevent water hammer?
- It is recommended to see the principle of water hammer in fluid mechanics and the structure and principle of the check valve. These are not a few words to talk about, you can understand, and the important thing is to study your own! Only in this way can I really understand.
- Q:Why is the intelligent water meter equipped with a check valve, still can not prevent the water meter idling?
- 2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.
- Q:How to prevent the backflow valve of medium
- The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
- Q:Classification of check valves
- 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.Structure check valve (One-way valve): divided by structure, can be divided into lift check valve, swing check valve and butterfly check valve three. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.Install vacuum check valve (One-way valve): should be installed in the top note of the following things: 1, the pipeline will not bear the weight of the check valve, large check valve (aetv One-way valve): should be independent of support, so that the pressure piping system from the.2, installation, pay attention to medium flow direction should be consistent with the body of the arrow direction.
- Q:Is the overcurrent valve a check valve?
- The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
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.
