Abstract

The utility model relates to a pressure release valve, which is arranged on a container wall and comprises a valve body and a sealing sleeve, wherein the sealing sleeve is sheathed outside the valve body, the valve body comprises an upper valve body and a lower valve body in mutual connection and fixation, the lower valve body is provided with a step inner hole, and a movable component is arranged on the inner hole. The pressure release valve provided by the utility model has the advantages that the dismounting and the mounting are convenient, pressure release and air inlet functions are realized, and in addition, the pressure release valve is applicable to containers made of different materials.

Description

A kind of Decompression valves
Technical field
The utility model relates to a kind of Decompression valves.
Background technique
Gasoline belongs to high volatile volatile inflammable liquid, and it is generally stored in the generation danger to avoid volatilization to leak in seal container; And the temperature of the storage environment of seal container is when raise, gasoline volatilization in petrol drum (tank) or container and cause container inner pressure to improve.As now opened oil drum or tank cap or operation during oil extraction, petrol drum (tank) or container inner pressure may abrupt releases and produce danger; At present on the market especially in North America market at present petrol drum (tank) be generally blow-molded article, there are two openings, one as gasoline filling and pour out.Another smaller opening is as pressure release and air inlet use, and its design has following shortcoming: the little vent cover of at every turn must outwarding winding, after using, again screw, and increase workload; And repeatedly screw, outward winding and can cause the easy breakage of seal ring or thread abrasion to lose efficacy; Screw meeting not in place cause gasoline volatilization thing to leak or during petrol drum (tank) rollover gasoline leak.
Summary of the invention
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides a kind of Decompression valves of being convenient to installation and removal that uses various material container.
The utility model is achieved through the following technical solutions:
A Decompression valves, is installed on container wall, comprises valve body, and is set in the stuffing box gland outside valve body, and described valve body comprises upper valve body and the lower valve body being interconnected and fixed; Described lower valve body is provided with inner bore of step, and endoporus is provided with the movable part that control valve body internal channel opens and closes.
Described movable part comprises movable spool and is set in the spring on movable spool, and on described movable spool, be also fixed with diaphragm seal, lower valve body is fixed in described spring one end, and one end is supported diaphragm seal on the step surface that is sealed in lower valve body inner bore.
Described upper valve body and lower valve body are threaded connection, and between valve body and container wall, by stuffing box gland tensioner, seal.
Described upper valve body is provided with air outlet hole.
Described upper valve body top is provided with flexible glue lid.
The utility model installing is simple, in the upper hole of boring applicable the utility model size of petrol drum (tank), then the utility model product is filled in hole, screws the screw thread of upper valve body and lower valve body, threaded expander by stuffing box gland press seal on hole.Before oiling, press flexible glue lid, shake-up activity spool, movable spool drives diaphragm seal to move downward, and valve body internal channel is opened, and petrol drum (tank) internal pressure discharges by Decompression valves internal channel voluntarily, release is loosed one's grip after completing, and spool sets back by spring action.Generally when petrol drum (tank) is 20 liters and pressure while reaching 0.5Kg/cm^2, use this valve can be by Pressure Drop to 0.08 Kg/cm^2 in 10 seconds.After pressure release completes, relieving hand can operate oiling, forms negative pressure in refueling process in container, so Decompression valves is can automatic air amount more smooth and easy to guarantee gasoline and be sucked out or pour out.
Accompanying drawing explanation
Fig. 1 is longitudinal sectional view of the present utility model.
In figure: 1-container wall, 2-stuffing box gland, 3-upper valve body, valve body under 4-, the movable spool of 41-, 42-diaphragm seal, 43-spring, 5-flexible glue lid.
Embodiment
Understanding for the ease of those skilled in the art, is described in further detail the utility model below in conjunction with accompanying drawing.It should be pointed out that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of Decompression valves, is installed on container wall 1, comprises valve body, and is set in the stuffing box gland 2 outside valve body, and described valve body comprises upper valve body 3 and the lower valve body 4 being interconnected and fixed; Described lower valve body 4 is provided with inner bore of step, and endoporus is provided with the movable part that control valve body internal channel opens and closes.
Described movable part comprises movable spool 41 and is set in the spring 42 on movable spool 41, on described movable spool 1, be also fixed with diaphragm seal 43, lower valve body 4 is fixed in described spring 42 one end, and one end is supported diaphragm seal 43 on the step surface that is sealed in lower valve body 4 endoporus.
Described upper valve body 3 is connected by threaded expander with lower valve body 4, and by upper and lower valve body, tighten up screw thread valve body is expanded, thereby by stuffing box gland 2 tensioners and container wall 1 sealing.Valve body is by stuffing box gland 2 and container wall 1 press seal.
Described upper valve body 3 is provided with air outlet hole; Described upper valve body 3 tops are provided with flexible glue lid 5.
The utility model installing is simple, in the upper hole of boring applicable the utility model valve body size of petrol drum (tank), then Decompression valves is filled in hole, screws the screw thread of upper valve body 3 and lower valve body 4, threaded expander by stuffing box gland 2 press seals on the hole of container wall 1.Before oiling, press flexible glue lid 5, shake-up activity spool 41, movable spool 41 drives diaphragm seal 43 to move downward, and valve body internal channel is opened, and petrol drum (tank) internal pressure discharges by Decompression valves internal channel voluntarily, release is loosed one's grip after completing, and movable spool 41 sets back by spring 42 effects.Generally when petrol drum (tank) is 20 liters and pressure while reaching 0.5Kg/cm^2, use this valve can be by Pressure Drop to 0.08 Kg/cm^2 in 10 seconds.After pressure release completes, relieving hand can operate oiling, forms negative pressure in refueling process in container, so Decompression valves is can automatic air amount more smooth and easy to guarantee gasoline and be sucked out or pour out.
The content of mentioning in above-described embodiment is not to restriction of the present utility model, is not departing under the prerequisite of inventive concept of the present utility model, and any apparent replacement is all within protection domain of the present utility model.
