Abstract
The utility model relates to a valve with changeable pressure and fixed flow in a water supply system. The front section of the utility model is the same as a common valve, and the rear section of the utility model is provided with a decompression chamber which is composed of a spring, a cone body with a bore and a rear chamber with a flow outlet. When water pressure is beyond the prescribed value, the cone body with a bore is inserted in the flow outlet to control water flow. The utility model can reduce surplus water supply pressure, automatically control the flow of the flow outlet, improve use flexibility and decrease pipeline noise. The utility model is suitable for various water supply systems for pipe networks.
Description
The utility model is about a kind of transformation constant current valve in the water system.
Valve is streamed as the most frequently used going out, and applies to widely in the pipe network water supply system.At present, valve is in the majority with the throttling form of piston, Electromagnetic Control, barrier film both at home and abroad.These valves go out the head piece flow and change with the variation of water pressure, do not control the water supply requirement of least favorable point in the system, cause the phenomenon of high-rise building upper strata lack of water.So, some units adopt the increasing water-aspirator pressure to improve water supply capacity.Cause the waste of electric power, water, fund like this.U.S. Pat 4,284,102 disclose a kind of decompression that has, and can close the current of water-supply line and reduce the stop valve of its too high pressure, but this valve is to use on feedwater transverse tube and standpipe, and can not control out the head piece flow voluntarily.
In view of the problem that existing valve exists, the purpose of this utility model provides a kind of pressure-independent transformation constant current of head piece flow valve of using.
The concrete solution of this model utility is to set up a underpressure chamber at the back segment of common valve, this underpressure chamber by spring, cone with holes, go out head piece after the chamber constitute.One end of cone with holes is a frustoconic shape, and the other end is a disc.Cone with holes and spring housing form a movably system together, place out behind the head piece among the chamber.When hydraulic pressure surpassed specified value, cone with holes was inserted to the aperture, flow cross-section is reduced, thereby controlled the flow that head piece, and the length that cone is inserted is decided by the size of pressure of supply water.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a general assembly drawing of the present utility model.
As shown in the figure, this valve distinguishes that by valve body (1), valve rod (2), valve handle (3), valve (4) and underpressure chamber constitute.This underpressure chamber by spring (5), cone with holes (6), go out head piece after chamber (7) form, an end of cone with holes (6) is a frustoconic shape, the other end is a disc.Cone with holes (6) and spring (5) are nested together, and form a movably system, place out behind the head piece among the chamber (7).When pressure of supply water is less than or equal to specified value, the elastic force of spring is less than pressure of supply water, cone with holes (6) is motionless, have only when supplying water and press when surpassing specified value, cone with holes (6) is inserted to aperture (8), and pressure of supply water is big more, and the degree of depth of insertion is big more, the effective discharge section area that then goes out head piece is more little, thereby has controlled the flow that head piece.
The utility model---transformation flow regulating valve, simple in structure, easy to manufacture, save water power and fund, improve soft property and elimination pipeline noise that valve uses, be applicable in all kinds of pipe network water supplies (the containing liquid) system.
Claims (2)
1, a kind of valve, by valve body (1), valve rod (2), valve handle (3) and valve are distinguished (4) composition, it is characterized in that being provided with a underpressure chamber at the back segment of valve, this underpressure chamber is by spring (5), cone with holes (6) and go out head piece after chamber (7) form, cone with holes (6) and spring (5) are nested together and form a movably system, place out behind the head piece among the chamber (7).
2, according to the said valve of claim 1, an end that it is characterized in that cone with holes (6) is a frustoconic shape, and the other end is a disc.
