Abstract
The utility model discloses a pressure regulation type safety valve for a high-pressure gas cylinder. The pressure regulation type safety valve for the high-pressure gas cylinder comprises an upper shell body, a lower shell body, a valve deck, a gland, a rubber plug, an upper spring base plate, a lower spring base plate, springs and a connecting rod, wherein a threaded sleeve, a threaded adjusting rod and a top cover are arranged at the upper end of the upper shell body, the connecting rod is sleeved with the threaded sleeve, the lower section of the threaded sleeve is arranged inside the upper shell body, the upper section of the threaded sleeve is arranged outside the upper shell body, the top cover is arranged at the upper end of the upper shell body, and the threaded adjusting rod is connected with the threaded sleeve in the top cover through threads after penetrating through the side face of the top cover. Compared with the prior art, the pressure regulation type safety valve for the high-pressure gas cylinder has the advantages that due to the fact that the threaded sleeve, the threaded adjusting rod and the top cover are additionally arranged based on a safety valve in the prior art, the set of safety valve with the adjustable strength is formed, the universality of existing valves can be improved, the opening strength of the valve can be set, the practicability of the safety valve is improved, and the safety valve can be popularized easily.
Description
Technical field
The utility model relates to a kind of gas cylinder Safety valve, relates in particular to a kind of voltage regulating type high voltage gas cylinder safely valve.
Background technique
Safety valve is a kind of safety protection valve; its open-shut device is subject under External Force Acting in normally off; pressure medium in equipment or pipeline raises, and while surpassing specified value, automatically opens, and by discharge medium outside system, prevents that in pipeline or equipment, pressure medium surpasses specified value.Safety valve belongs to self-acting valve class, is mainly used on boiler, pressurized container and pipeline, and pilot pressure is no more than specified value, and personal safety and equipment have been moved to important protective action.And Safety valve of the prior art need be selected according to various air pressure the valve of respective strengths, so versatility is just not strong, and practicability is wideless.
Model utility content
The purpose of this utility model provides a kind of voltage regulating type high voltage gas cylinder safely valve with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises upper shell, lower shell body, valve gap, gland, rubber plug, upper spring backing plate, lower spring backing plate, spring and connecting rod, the upper end of described upper shell is provided with screw shell, threaded adjusting bar and top cover, described screw shell is set on described connecting rod, and the hypomere of described screw shell is placed in described upper shell, the epimere of described screw shell is placed in outside described upper shell, the upper end of described upper shell is provided with top cover, described threaded adjusting bar through behind the side of described top cover with described top cover in described screw shell be threaded connection.
Further, the port outer rim of described valve gap is also provided with sealing rubber ring.
The beneficial effects of the utility model are:
The utility model is a kind of voltage regulating type high voltage gas cylinder safely valve, compared with prior art, on the utility model safety valve in the prior art, screw shell, threaded adjusting bar and top cover have been increased, form a set of safety valve that can regulation safety valve intensity, not only can improve the versatility of existing safety valve, but also can set the intensity of valve open, and improved the practicability of safety valve, be conducive to promote.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of voltage regulating type high voltage gas cylinder safely valve described in the utility model.
In figure: 1-upper spring backing plate, 2-spring, 3-upper shell, 4-lower spring backing plate, 5-rubber plug, 6-sealing rubber ring, 7-lower shell body, 8-top cover, 9-threaded adjusting bar, 10-connecting rod, 11-gland, 12-screw shell, 13-valve gap.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises upper shell 3, lower shell body 7, valve gap 13, gland 11, rubber plug 5, upper spring backing plate 1, lower spring backing plate 4, spring 2 and connecting rod 10, the upper end of described upper shell 3 is provided with screw shell 12, threaded adjusting bar 9 and top cover 8, screw shell 12 is set on connecting rod 10, and the hypomere of screw shell 12 is placed in upper shell 3, the epimere of screw shell 12 is placed in outside upper shell 3, the upper end of upper shell 3 is provided with top cover 8, threaded adjusting bar 9 through behind the side of top cover 8 with top cover 8 in screw shell 12 be threaded connection, the port outer rim of valve gap 13 is also provided with sealing rubber ring 6.Screw shell 12, threaded adjusting bar 9 and top cover 8 on the utility model safety valve in the prior art, have been increased, form a set of safety valve that can regulation safety valve intensity, regulate threaded adjusting bar 9 can make screw shell 12 move up and down, thereby promote the intensity that upper spring backing plate 1 changes spring 2, not only can improve the versatility of existing safety valve, but also can set the intensity of valve open, improved the practicability of safety valve.
