Abstract

The utility model relates to an exhaust valve device of a pressure container. The exhaust valve device comprises a silica gel valve spool (1), an inner valve sleeve (2), a valve body (3), a valve bonnet (4), gaskets (5) and a jump spring (6). The silica gel valve spool is mounted on a silica gel valve spool seat on the upper portion of the inner valve sleeve. The valve body (3) is sleeved outside the inner valve sleeve (2). The gaskets (5) are arranged at the bottom of the inner valve sleeve (2), and the valve bonnet (4) fixedly covers the inner valve sleeve (2), the valve body (3) and the gaskets (5) in an injection molding manner. Fastening slots (7) are arranged the bottom of the inner valve sleeve (2) or the positions of the gaskets (5), and the jump spring (6) is detachably mounted on the fastening slots (7). A space is reserved between the inner bottom surface of the valve bonnet (4) and the upper portion of the silica gel valve spool (1). The upper end of the silica gel valve spool is provided with a sheath (8) which is arranged in the space between the valve bonnet and the silica gel valve spool. During use of the exhaust valve device having the above structure, the silica gel valve spool is not easy to be damaged by high temperature and high pressure during injection molding of the valve bonnet, and accordingly, sealing performance is fine.

Description

A kind of discharge valve apparatus of pressurized container

Technical field

The utility model belongs to household electric appliance hardware manufacturing technology field, is specifically related to a kind of discharge valve apparatus of pressurized container.

The discharge valve apparatus of existing pressurized container mainly is made up of cover, valve body, valve gap, pad and jump ring in silica gel spool, the valve usually, and the silica gel spool is installed on the silica gel valve core case on cover top in the valve; Valve body is socketed in the outside of cover in the valve, and pad is located at the bottom of cover in the valve, and valve gap wraps cover, valve body and pad in silica gel spool, the valve through Shooting Technique; In valve, have a draw-in groove between cover bottom and the pad, jump ring is removably mounted on the draw-in groove, the discharge valve apparatus that is used for pressurized container of this structural design; When the injection moulding valve gap,, and there is the injection moulding high pressure because high temperature is very high; The silica gel spool is damaged, cause its sealability to reduce.

The model utility content

The purpose of the utility model is to provide a kind of silica gel spool of can effectively protecting to avoid HTHP destruction, the discharge valve apparatus that is used for pressurized container of good seal performance.

The purpose of the utility model is achieved in that a kind of discharge valve apparatus of pressurized container; Comprise cover (2), valve body (3), valve gap (4), pad (5) and jump ring (6) in silica gel spool (1), the valve; Silica gel spool (1) is installed on the silica gel valve core case on cover (2) top in the valve, and valve body (3) is socketed in the outside of cover (2) in the valve, and pad (5) is located at the bottom of cover (2) in the valve; Valve gap (4) wraps cover (2), valve body (3) and pad (5) in the valve through Shooting Technique; Cover (2) bottom or pad (5) locate to have a draw-in groove (7) in the said valve, and jump ring (6) is removably mounted on the draw-in groove (7), it is characterized in that: have a space between said valve gap (4) inner bottom surface and silica gel spool (1) top; The upper end portion of said silica gel spool (1) is provided with a sheath (8), and sheath (8) is positioned at the space between valve gap (4) and the silica gel spool (1).

The bottom of said sheath (8) offers heavy stand (80), and the upper end of silica gel spool (1) is socketed in the heavy stand (80).

Cover (2) middle part has exhaust passage (20) in the said valve.

The top of said valve gap (4) offers exhaust port (40).

The good effect of the utility model: be provided with a sheath in the upper end portion of silica gel spool, when the injection moulding valve gap, silica gel spool and high temperature and high pressure environment isolated, it is not damaged, effectively guarantee the sealability of silica gel spool.

Embodiment

Below in conjunction with accompanying drawing the discharge valve apparatus embodiment of the said pressurized container of the utility model is done further explain.

Shown in Fig. 1-9; The discharge valve apparatus of the described pressurized container of the utility model, mainly by overlap 2 in silica gel spool 1, the valve, valve body 3, valve gap 4, pad 5 and jump ring 6 form, silica gel spool 1 is installed on the silica gel valve core case 21 on cover 2 tops in the valve; Valve body 3 is socketed in the outside of cover 2 in the valve; Pad 5 is located at the bottom of cover 2 in the valve, valve gap 4 through Shooting Technique with overlap 2 in the valve, valve body 3 and pad 5 wrap, cover 2 bottoms or pad 5 places have a draw-in groove 7 in the valve; The draw-in groove 7 of this mode of execution is the shoulder of the single order halfpace outside the upper surface that is opened in pad 5; Constitute draw-in groove 7 jointly with cover 2 bottom in the valve, can certainly in valve, overlap on the excircle of 2 lower bottom part or pad 5 and directly offer draw-in groove 7, jump ring 6 is removably mounted on the draw-in groove 7.Because of valve gap 4 when the injection moulding, can have the injection moulding high pressure, and the temperature of injection moulding is usually about 200 degree; And silica gel spool 1 is high temperature resistant usually about 150 degree, surpasses the easy high temperature ageing of this temperature even dissolves, bad broken in order to make silica gel spool 1 avoid HTHP when valve gap 4 injection mouldings; Between valve gap 4 inner bottom surfaces and silica gel spool 1 top, be designed with a space; Be provided with a sheath 8 in the upper end portion of silica gel spool 1, in the space of sheath 8 between valve gap 4 and silica gel spool 1, install for ease; The bottom of sheath 8 offers heavy stand 80, and the upper end of silica gel spool 1 is socketed in the heavy stand 80.In order to guarantee the smooth and easy exhaust at discharge valve apparatus, cover 2 middle parts are designed with exhaust passage 20 in valve in addition, and the top of valve gap 4 offers exhaust port 40.The discharge valve apparatus of this structure, wherein cover 2, valve gap 4, the high temperature resistant plastic material of pad 5 common employings are processed in the valve, and valve body 3 can adopt metallic material to make, and jump ring 6 adopts usually has better flexible stainless steel metal wire making.
