Introduction
It is a new authorized water power control valve of our company, awarded the national patent.
It’s mainly available for service pipe on diesel pump and electric pump , to ensure pump sets to supply water at a rated head and flow, specially for preventing overloading at a low head and overloaded starting. It can be used for water supply and fire pump system in pipeline for auto-inspection and decompression running.
This constand head/check valve is widely to use for water supply system such as daily, industrial and smelting and fire protection, and a multi parallel connection pump sets system etc. it’s a ideal valve for keeping pipeline safety and running high efficiency
2. Application of this constant head check valve
It solves problems on application of pumps in the field of water industry.
2.1 Pump can be started at low axis power to decrease the drive start power
2.2 Pump can be worked under a huge of pressure diversification , enable working in a high efficiency for saving energy.
2.3 Pump can be worked under a huge of pressure diversification ,enable working as the model section situation for ensuring the suited drive equipment non-overloaded
2.4 Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded
2.5 Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded
2.6 When pump is stopped, ensuring pump and pipeline connection is cutoff to prevent water flowing back

- 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: To prevent water meter rotation, where should the check valve be installed?
- The two check valves are already installed
- Q: God, can you explain to me in detail why?
- Check valve in the valve in front. To prevent water from flowing back.
- Q: What's the size of the check sleeve?
- According to the quota items can be set corresponding to the valve diameter less than DN40, the thread sets, DN50 sets of flange connection can, according to the actual unit price to enter it.
- Q: What are the differences between the vertical check valve and the horizontal check valve in function and principle?.
- The check valve has a baffle inside it, usually closed by gravity,The function and working principle are basically indistinguishable
- Q: What are the differences between the vertical check valve and the horizontal check valve?
- Difference：The main difference is that the valve center and valve seat are placed upright and horizontally placed, usually designed with the pipe.Brief introduction:Vertical check valve: because of the pressure acting on the inlet end of the pipeline, the spring resistance is overcome so that the valve is opened or closed. When the inlet end of the media pressure is lower than the exit end, the spring will push the spool to the valve seat, so that the valve closed, to prevent the flow of medium, so the beginning of the role of back.Horizontal check valve, also known as check valve, its role is to prevent the medium back in the pipeline. 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.
- Q: What is the difference in price between the check valve HH48X-10C and the HH49X-10C?
- Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.
- Q: Check valve h44h-25p what does that mean?
- H- stainless steel4- flange connection4- rotary single structure check valveH sealing material is Cr13 stainless steel25- pressure 2.50MPAP-18-8 stainless steelH44h-25p= stainless steel flange connection, swing type single check valve pressure 2.50MPA valve body, material 18-8 stainless steel
- Q: Does the check valve of the flue of the range hood work?
- There is also a smoke exhaust smoke fire check valveThe utility model is installed at the rear end of a kitchen fume exhauster or a toilet exhaust fan to a common exhaust pipe inlet with a fireproof grade, and the fan is opened (exhaust gas) when working. In the fan does not work naturally closed (to prevent backflow, waste) or common duct inside temperature reaches a set value can be automatically closed, and within the stipulated period of time to meet the fire performance requirements, the role of smoke from fire retardant valve. This metal valve works on more, the basic effect should be good.
- Q: What are the specifications of the DN200 check valve?
- DN200 is a specification.The principle of the check valve, the check valve, the opening and closing parts, depend on the flow of the medium and the power to open or close on its own, so as to prevent the backflow of the medium, called the 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. The check valve is divided into three kinds: lift check valve, swing check valve and butterfly 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. A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.
