Description

A kind of low temperature pressure regulator valve
Technical field
The utility model belongs to pressure regulator valve technical field, specifically relates to a kind of low temperature pressure regulator valve.
Background technique
Pressure regulator valve is a kind of in industrial automation process control field, by accepting the control signal that regulation unit exports, removing the final control unit changing gas flow and pressure, be generally made up of actuator and valve by power operation.But traditional pressure regulator valve, due to itself structural restriction, cannot be applied to cryogenic media operating mode, meanwhile, the stability of valve rod own is not good enough, easily produces vibrations, impact location.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, a kind of low temperature pressure regulator valve is provided, by arranging the parts such as diaphragm screw rod, lifting arm, lifting spring, pressure regulator valve can be applied at low ambient temperatures, compare with conventional ball valve, there is good stability, little by externally temperature influence, the features such as using scope is larger, applied range, easy to use.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of low temperature pressure regulator valve, comprises valve body lining, described valve body lining is arranged 0 type circle and valve body, arranges valve seat in described valve body; Arrange in described valve body lining and promote passage and promote spring, described lifting spring is arranged sealing seat and the 3rd packing ring, described 3rd packing ring arranges lifting arm, described lifting arm is arranged diaphragm screw rod, described diaphragm screw rod is connected with diaphragm, described diaphragm arrangement, on diaphragm fitting seat, described diaphragm fitting seat is arranged screw, the second packing ring, the second nut and spring housing, arranges spring guide, set spring, the first nut and the first packing ring in described spring housing; Described spring housing also arranges knob assembly.
The beneficial effect that the utility model has: by arranging the parts such as diaphragm screw rod, lifting arm, lifting spring, pressure regulator valve can be applied at low ambient temperatures, compare with conventional ball valve, there is good stability, little by externally temperature influence, the features such as using scope is larger, applied range, easy to use.Therefore the utility model has the features such as structure is simple, reasonable in design.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1, spring housing; 2, spring guide; 4, set spring; 5, the first nut; 6, the first packing ring; 7, screw; 8, the second packing ring; 9, the second nut; 10, valve body; 11, valve seat; 12, passage is promoted; 13, spring is promoted; 14, valve body lining; 15, knob assembly; 17, diaphragm; 18, diaphragm fitting seat; 19, diaphragm screw rod; 20, lifting arm; 21,0 type circle; 22, sealing seat; 23, the 3rd packing ring.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of low temperature pressure regulator valve, as shown in Figure 1, comprises valve body lining, described valve body lining is arranged 0 type circle and valve body, arranges valve seat in described valve body; Arrange in described valve body lining and promote passage and promote spring, described lifting spring is arranged sealing seat and the 3rd packing ring, described 3rd packing ring arranges lifting arm, described lifting arm is arranged diaphragm screw rod, described diaphragm screw rod is connected with diaphragm, described diaphragm arrangement, on diaphragm fitting seat, described diaphragm fitting seat is arranged screw, the second packing ring, the second nut and spring housing, arranges spring guide, set spring, the first nut and the first packing ring in described spring housing; Described spring housing also arranges knob assembly.
Low temperature pressure regulator valve, by arranging the parts such as diaphragm screw rod, lifting arm, lifting spring, makes pressure regulator valve apply at low ambient temperatures, compares with conventional ball valve, there is good stability, little by externally temperature influence, the features such as using scope is larger, applied range, easy to use.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
