Abstract

Disclosed is a gas outlet seat, which is characterized in that: the external side of an air cock is sheathed with an outer ring and an elastic block ring sealed through a locking ring. A break valve is arranged in the cavity of a base. A filter arranged in the base cavity and an iron shot, a spring and a gasket form a first stage sealing mechanism. A sealing connecter is arranged between the air cock and the base. Both sides of the sealing connecter are respectively connected with the base and the air cock. A locking lever used for chucking plugs is arranged in the groove on the flank of the air cock. A second stage sealing mechanism composed of a top core, a spring and a gasket is arranged in sealing connecter cavity. The utility model has the advantages of favorable sealing property and easy use.

Description

The gas outlet seat

Technical field

The utility model relates to the gas transmission technical field, particularly a kind of gas outlet seat that is suitable for medical central gas supply system.

Background technique

The gas outlet seat is mainly used in central gas supply, existing gas outlet seat mainly by base, upper valve body,

Outer shroud, spring, air door body and rubber cushion are formed, spring, air door body and rubber cushion are combined the sealing mechanism that has constituted the gas outlet seat, be placed between base and the upper valve body, two grooves of upper valve body are respectively arranged with card, block plug when external plug inserts, outer shroud is fixed on the outside of upper valve body by screw, and its working principle is that the gas in the system directly enters the outlet port base, under the effect of sealing mechanism, gas is enclosed in the base, during using gases, plug is inserted outlet port, at this moment two of upper valve body cards block plug, plug withstands air door body simultaneously, the spring stress compression, and rubber cushion breaks away from original position, gas flows into plug, its shortcoming is that outlet port has adopted the single-stage sealing, and the tightness instability is got plug with rotary or push-out type, use the easy loose or dislocation of a base plate, generally be the shared external stop valve of several exits seat, like this, when an outlet port breaks down, then to close stop valve, influence the use of other outlet port.

Summary of the invention

The purpose of this utility model provides a kind of good seal performance, gas outlet seat easy to use.

The utility model is to realize like this, it comprises base, packing ring, nut, sealing gasket, valve, outer shroud, locking ring, check lock lever, plunger tip, spring and locating stud, it is characterized in that being set with outer shroud in the outside of valve, with the elasticity baffle ring, between valve and the outer shroud by locking ring and spring sealed, stop valve is arranged in the cavity of base, be arranged on filter and steel ball in the base cavity, spring and sealing gasket are formed first order sealing mechanism, between valve and base, be provided with seal connector, the both sides of seal connector are connected with valve with base respectively, in the groove of valve side, be provided with the check lock lever that is used to tighten plug, in the chamber of seal connector body, be provided with by plunger tip, spring and sealing gasket are formed second level sealing mechanism.

The utility model is to be provided with stop valve on each outlet port, and with the shared chamber of base, in the outlet port cavity, be provided with filter and adopted double-layer seal, therefore have good seal performance and advantage easy to use.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described;

Fig. 1 is the structural representation of gas outlet seat.

Embodiment

As shown in Figure 1, this gas outlet seat comprises interface 1, nut 2, base 3, stifled 4, packing ring 5,19, sealing gasket 6,9,17,20,23, nut 7, stop valve 8, elasticity baffle ring 10, valve 11, outer shroud 12, locking ring 13, check lock lever 14, circlip 15, plunger tip 16, spring 21,25, seal connector 22, steel ball 24, filter 26 and locating stud 28, be set with outer shroud 12 and elasticity baffle ring 10 in the outside of valve 11, seal by locking ring 13 and spring 27 between valve 11 and the outer shroud 12, stop valve 8 is arranged in the cavity of base 3, be arranged on filter 26 and steel ball 24 in base 3 cavitys, spring 27 and sealing gasket 23 are formed first order sealing mechanism, between valve 11 and base 3, be provided with seal connector 22, the both sides of seal connector 22 are connected with valve 11 with base 3 respectively, in the groove of valve 11 sides, be provided with the check lock lever 14 that is used to tighten plug, in the chamber of seal connector 22 bodies, be provided with by plunger tip 16, spring 21 and sealing gasket 23 are formed second level sealing mechanism, its working principle is, when external plug inserts outlet port, the check lock lever 13 of gas Zi, one of the lunar mansions 11 both sides is locked plug, plug also withstands the upper end of plunger tip 16 simultaneously, make sealing gasket 23 dislocations of second level sealing mechanism, plunger tip 16 lower ends contact with steel ball 24 simultaneously, make the spring 25 of steel ball 24 lower ends be subjected to force compresses, sealing gasket 23 dislocations of first order sealing mechanism, gas flows into external plug from base 3, starts working.
