Abstract
The utility model discloses a detachable normal closed valve, comprising a valve body (7), a valve plug (3), a small gasket (4), a spring (1), a spring sleeve (2) and a big gasket (8), wherein, the valve body (7) is covered with the big gasket (8) and is connected with a container by screw threads; the valve plug (3) is provided with a straight hole (5) and a cross bore (9) which are communicated with each other; the small gasket (4) is closely attached to the valve body; the valve plug (3) passes through the small gasket (4) and is sleeved in the valve body (7); the spring (1) presses against a boss end of the valve plug (3), so that the valve plug is closely attached to the small gasket (4); the spring sleeve (2) is sleeved on the spring (1) and is fixed with the valve body (7) by screw threads; the center of the bottom of the spring sleeve (2) is provided with a bottom hole (11) which is communicated with a spring sleeve cavity (10). The normal closed valve is detachable when connected with the container, and is easy to install; an opener of the valve is arranged internally, which is safe and reliable; the valve can bear a high pressure, thereby having a long service life.
Description
Technical field
The utility model relates to a kind of normal closed gate, particularly relates to a kind of detachable normal closed gate that stored-gas or liquefied gas container are used that is used for.
Background technique
The stored-gas of using in the modern day life or the pressurized container of liquid gas, as hair jelly jar, high mountain oxygen tank etc., the valve of these pressurized containers and tank body pressing are one, valve is non-dismountable, in case valve or tank body damage, and must all discard, and cause waste; The opening mechanism of valve exposes, and accident is opened or collided with easily, causes gas or gas leak, poor stability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the detachable normal closed gate that provides a kind of pressurized container that is used for stored-gas or liquid gas to use.
The utility model is achieved through the following technical solutions: a kind of detachable normal closed gate assembly comprises valve body, spool, little sealing gasket, spring, spring spool, big sealing gasket.The valve body upper surface has the frock groove, and the valve body side external surface has screw thread, and is with big sealing gasket, be connected and fixed with container threads, and by big sealing gasket sealing.The spool epimere has a straight hole along axis, in the straight hole bottom sides one cross-drilled hole is arranged, and cross-drilled hole communicates with straight hole.Little sealing gasket is close in the valve body, and spool has the straight hole end and passes from the center hole of little sealing gasket, is sleeved in the valve body, and the top is to valve body frock groove bottom.Spring withstands spool boss end, makes itself and little sealing gasket compress applying.The spring spool pocketed springs also is threaded fixingly with valve body, and little sealing gasket is pressed in the valve body, realizes the outer side sealing of little sealing gasket, and there is a bottom outlet at spring spool bottom centre place, and bottom outlet communicates with the spring spool chamber, and there is the frock groove spring spool bottom surface.
Wherein valve body, spring spool are metallic material; Four directions in the frock groove of valve body upper surface, interior six sides, interior all directions, to hole shape or four directions, six sides, from all directions; The frock groove of spring spool bottom surface can be straight groove, cross recess or four directions, six sides, from all directions.
When valve was in closed state, spring compressed the formation sealing with spool and little sealing gasket, and the straight hole on the cut-out spool is communicated with the spring spool chamber, makes container be in closed state.When to the spool application of force, it is pressed in valve body, remove the sealing that spool and little sealing gasket form, the bottom outlet of straight hole, cross-drilled hole and the spring spool chamber of spool, spring spool forms circulation passage at this moment, allows the outflow that flows to of medium.Remove the application of force, valve recovers closed state.
Normal closed gate of the present utility model adopts with container and is threaded, and is detachable, and normal closed gate and container are appointed one of damage, and replaceable, easy for installation, valve open mechanism is built-in, and is safe and reliable, and valve integral body is metallic material, bears the pressure height, long service life.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
A kind of detachable normal closed gate comprises valve body 7, spool 3, little sealing gasket 4, spring 1, spring spool 2, big sealing gasket 8.Valve body 7 upper surfaces have frock groove 6, and valve body 7 side external surfaces have screw thread, and are with big sealing gasket 8, be connected and fixed with container threads, and by big sealing gasket 8 sealings.Spool 3 epimeres have a straight hole 5 along axis, in straight hole 5 bottom sides one cross-drilled hole 9 are arranged, and cross-drilled hole 9 communicates with straight hole 5.Little sealing gasket 4 is close in the valve body, and spool 3 has the straight hole end and passes from the center hole of little sealing gasket 4, is sleeved on 7 li of valve bodies, and the top is to valve body frock groove 6 bottoms.Spring 1 withstands spool 3 boss ends, makes itself and little sealing gasket 4 compress applying.Spring spool 2 pocketed springs 1 also are threaded fixing with valve body 7, and little sealing gasket 4 is pressed on 7 li of valve bodies, and realizing little sealing gasket 4 outer side sealings, there is a bottom outlet 11 at spring spool 2 bottom centre place, bottom outlet 11 communicates with spring spool chamber 10, and there is frock groove 12 spring spool 2 bottom surfaces.
When to spool 3 application of forces, it to 7 li pressures of valve body, is removed the sealing that spool 3 and little sealing gasket 4 form, this moment, straight hole 5, the cross-drilled hole 9 of spool 3 formed circulation passages with the bottom outlet 11 of spring spool chamber 10, spring spool, allowed the outflow that flows to of medium.After the application of force to spool 3 removed, spring 1 compressed spool 3 and little sealing gasket 4 and forms sealing, and the straight hole 5 on the cut-out spool 3 is communicated with spring spool chamber 10, makes container be in closed state.
