As shown in figure 1, existing gas receiver includes gas receiver assembly 1a, housing 2a, spring 3a and draw ring 4a.Wherein,
Existing gas receiver realizes that gas receiver assembly is separated with the valve port of housing bottom using upper pushing-type, so as to realize miscellaneous in gas receiver
Matter flows out at valve port.Using the opening ways inconvenient operation of upper pushing-type, and push up gas receiver assembly so that gas receiver
Assembly is moved towards dewatering outlet direction, and gas receiver assembly easily produces interference with dewatering outlet, so as to influence the impurity of gas receiver to discharge
Effect.
Utility model content
The utility model in order to solve existing gas receiver discharging valve using upper pushing-type open when inconvenient operation and easily with
The problem of gas receiver dewatering outlet produces interference.
The utility model provides a kind of gas receiver discharging valve to achieve these goals, and it is arranged on the bottom of gas receiver,
Including：Housing, the valve assembly that discharges water, return spring and the manual draw ring discharged water on valve assembly is located at, the top tool of the housing
There is valve port, the top of the valve assembly that discharges water is provided with the plug being engaged with the valve port, and the return spring is located at described stifled
Between head and the housing.
Preferably, there is gap between the plug and the case inside wall.
Preferably, the plug is T-type structure, including the closure face at top and connection positioned at the closure face bottom side it is convex
Platform；It is sleeved at the top of the return spring on the connection boss, the bottom of the return spring is contacted with the housing.
Preferably, in addition to the sealing gasket at the top of the plug, the top of the sealing gasket raises up
Spherical, the spherical is just set to the valve port.
Preferably, it is also equipped with filter screen in the inner of the valve port.
Preferably, the outer wall of the housing is provided with external screw thread.
Effect of the present utility model is：Discharging valve is opened using pull-down in this programme, during unlatching, and drop-down is drawn manually
Ring is realized, during closing, is sealed by the pretightning force of return spring itself.It is convenient to open, it is to avoid gas receiver assembly and storage
The dewatering outlet of inflator produces interference.
Brief description of the drawings
, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only described in the utility model
Some embodiments, for those of ordinary skill in the art, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of existing gas receiver discharging valve.
Fig. 2 is the structural representation of gas receiver discharging valve in the utility model embodiment.
In prior art diagram：1a- gas receiver assembly 2a- housing 3a- spring 4a- draw rings
In the present embodiment figure：1- filter screen 2- return spring 3- housings 4- discharges water the manual draw rings of valve assembly 5-
6- valve port 7- plug 8- sealing gaskets
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
A kind of gas receiver discharging valve shown in Figure 2, being provided for the utility model embodiment, it is arranged on gas receiver
Bottom, it includes：Housing 3, the valve assembly 4 that discharges water, return spring 2 and is located at the manual draw ring 5 discharged water on valve assembly 4, wherein,
The top of housing 3 has valve port 6, and the top for the valve assembly 4 that discharges water is provided with the plug 7 being engaged with valve port 6, and return spring 2 is located at
Between the plug 7 and housing 3.That is, discharging valve is using pull-down unlatching in this programme, during unlatching, manual draw ring 5 is pulled down real
Existing, during closing, by return spring 2, the pretightning force of itself is sealed.To open convenient, it is to avoid gas receiver assembly and gas receiver
Dewatering outlet produce interference.It should be noted that in order to ensure pulling downward on during manual draw ring 5, impurity can be suitable from discharging valve
Profit outflow, it should be ensured that there is gap between plug 7 and case inside wall 6.
Further, in the present embodiment, as shown in Fig. 2 plug 7 be T-type structure, including top closure face and positioned at closure
The connection boss of face bottom side；The top of return spring 2 is sleeved on connection boss, and now, closure face is played pushes up to return spring 2
The spacing effect in end；The bottom of return spring 2 is contacted with housing 3, and housing 3, which is played, carries out the spacing work in bottom to return spring 2
With.For further, it can also be installed at the top of plug 7 in a sealing gasket 8, the present embodiment, the top of sealing gasket 8 is upward
