Embodiment

[0019] Such as figure 1 In the adjustable pressure relief / sustaining valve shown, the valve body 1 is a right-angle tee, which is composed of an upper valve body and a horizontal valve body. The horizontal valve body has a screw hole 17 for installing a pressure gauge near the water inlet and a There is a partition 16 in the direction to prevent the medium from flowing directly from the water inlet to the water outlet. There is a water outlet hole c oblique to the axis of the horizontal valve body in the direction of the water outlet next to the connection between the upper valve body and the horizontal valve body, so that the medium is connected to the water inlet and the water outlet after the valve is opened. There is a conical hole a in the middle of the horizontal valve body; an adjustment sleeve 3 is slipped in the valve hole of the upper valve body, and an O-shaped sealing ring 9 is provided between the mating surfaces, which can move up and down with the adjustment sle...

Abstract

The invention relates to an adjustable pressure-relieving / holding valve which is characterized by being provided with a right-angle tee valve body consisting of an upper valve body and a horizontal valve body, wherein the horizontal valve body is provided with a screw hole for installing a pressure meter in the direction close to a water inlet and is provided with a partition wall in the direction close to a water outlet, the connecting part of the upper valve body and the horizontal valve body is provided with a water exhaust hole oblique crossing with the axle line of the horizontal valve body in the direction close to the water outlet of the partition wall, the middle part of the horizontal valve body is provided with a conical bore, a regulating sleeve is matched in a valve hole of the upper valve body in a sliding manner, the center of the regulating sleeve is provided with a valve plug shaft matched with the conical hole, and a locking nut and a hand wheel connected with the regulating sleeve are screwed on the outer diameter of the upper valve body. The invention has the advantages of simple structure, wide pressure-regulating range, and capabilities of conveniently regulating starting pressure according to different requirements, being used as a pressure-holding valve and also maintaining stability of water supply pressure.

Description

technical field [0001] The invention relates to a valve, in particular to a pressure relief / pressure sustaining valve. Background technique [0002] Pressure relief valves are widely used in water supply systems to respond quickly to pressure fluctuations and release quickly, preventing damage to pipes and equipment due to a sharp rise in pressure. At present, there are 500X pressure relief / pressure sustaining valves produced by the valve factory. This kind of valve has complex structure, troublesome operation and high cost. Contents of the invention [0003] The main purpose of the present invention is to overcome the deficiencies in the prior art, so as to develop an adjustable pressure relief / sustaining valve with simple structure and convenient operation. [0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: an adjustable pressure relief / pressure sustaining valve, which is characterized in that...
