Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of Depressure valve.
Background technique
Reduction valve is by regulating, inlet pressure being reduced to the outlet pressure of a certain needs, and rely on the energy of medium itself, makes outlet pressure automatically keep stable valve.Reduction valve is a throttle element that local resistance can change, and by changing orifice size, the kinetic energy of flow velocity and fluid is changed, and causes the different pressure losses, thereby reaches the object of decompression.Then rely on the adjusting of controlling with regulating system, the fluctuation of downstream pressure and spring force are balanced each other, make downstream pressure keep constant in certain margin of error.And at present common reduction valve cannot regulation output force value, once and after spring damages or elasticity weakens, cannot find at once, to equipment, can produce potential safety hazard.
Model utility content
The purpose of this utility model is: in order addressing the above problem, to provide a kind of Depressure valve simple in structure, easy to use, to have realized reduction valve pressure regulate by adjusting screw rod, increased safety valve simultaneously and prevent that pressure-relief valve spring lost efficacy, and realized duplicate protection.
To achieve these goals, the technical solution of the utility model is:
A Depressure valve, comprises housing, safety valve, adjusting screw rod, end cap, pressing plate, adjusting diaphragm, sealing gasket for valve, the first spring, the second spring and valve mandril; Described enclosure interior is provided with the first cavity and the second cavity; Described the first cavity is provided with cup dolly; Described the first spring and sealing gasket for valve are arranged in described cup dolly; Described valve mandril is arranged in described cup dolly; Described valve mandril one end is connected with described sealing gasket for valve, and the other end is connected with described adjusting diaphragm; Described first spring one end is connected with described sealing gasket for valve, and the other end is connected with described housing; Described safety valve is arranged on described the second cavity; Described adjusting diaphragm, pressing plate, the second spring and adjusting screw rod connect successively, and are arranged in described the second cavity; Described end cap is arranged on described housing; Described adjusting screw rod is arranged in described end cap.
Further, described the first cavity connects suction port; Described the second cavity connects air outlet.
Further, described the first cavity is provided with high pressure indicating pressure gage; Described the second cavity is provided with low pressure indicating pressure gage.
Further, described adjusting screw rod is connected with described end cap by screw thread.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model, owing to being provided with cup dolly in the first cavity, is also provided with sealing gasket simultaneously in cup dolly, utilizes sealing gasket the first cavity and the second cavity can be isolated completely, guarantees the sealability of reduction valve, sealing gasket of the present utility model connects valve mandril, valve mandril connects pressing plate successively simultaneously, the second spring and adjusting screw rod, thereby the delivery pressure that can realize reduction valve regulates, when delivery pressure reaches settings, to regulate under pressure the diaphragm jack-up that makes progress, by valve mandril, drive sealing gasket to move up, thereby the gap between valve mandril and cup dolly is blocked up, after delivery pressure reduces, under the effect of the second spring, again sealing gasket is moved down, thereby finally realizing pressure regulates, the utility model is owing to being provided with safety valve on the second housing, spring failure in reduction valve, utilize safety valve automatic vent, until air pressure is while dropping to setting value, automatically close again, and keep sealing.
