Description
Technical field
The utility model relates to valve technology field, the stop valve of particularly a kind of improvement.
Background technique
At present, stop valve is as the one of modulating valve, and structure is low in and high out, and structure is low in and high out, and namely the entrance location of valve body exit position that is lower, valve body is higher, and existing stop valve exists that flow is little, part is many, the complicated problem such as to cause at the bottom of production capacity of packaging technology.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides one to strengthen ventilation flow rate, reduces part thus improves packaging efficiency, greatly improving the stop valve of production capacity.
For achieving the above object, the utility model is by the following technical solutions: a kind of stop valve of improvement, comprise copper sleeve body, copper sleeve body internal upper part is provided with button, button lower end is provided with grip assembly, is provided with shell fragment between button and grip assembly, and described grip assembly lower end is provided with spool, be provided with spring in the middle part of spool and between grip assembly, between spool lower end and grip assembly, be provided with spool packing ring.
Wherein, described grip assembly comprises the upper grip assembly being located at shell fragment lower end, and upper grip assembly top is provided with taper hole, upper grip assembly bottom is provided with bulge loop, upper grip assembly lower end is connected with lower grip assembly, and lower grip assembly inwall offers the groove be connected with bulge loop, and lower grip assembly lower end offers scrobicular ring.
Wherein, be provided with the guard ring that cross section is stepped between described button and copper sleeve body, guard ring bottom and upper grip assembly are connected.
Wherein, described copper sleeve body bottom is provided with outside thread packing ring.
The utility model beneficial effect is: it comprises copper sleeve body, copper sleeve body internal upper part is provided with button, button lower end is provided with grip assembly, shell fragment is provided with between button and grip assembly, described grip assembly lower end is provided with spool, spring is provided with in the middle part of spool and between grip assembly, spool packing ring is provided with between spool lower end and grip assembly, the utility model by being provided with spring in the middle part of spool and between grip assembly, such spool vent is once large, throughput after ventilation uses also can be thereupon once large, Component quantity reduces, eliminate original valve core case and valve core case O type circle, packaging technology becomes simple, substantially increase manufacturing efficiency.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
reference character:
1---copper sleeve body 2---button
3---shell fragment 4---spool
5---spring 6---spool packing ring
7---upper grip assembly 8---lower grip assembly
9---guard ring 10---outside thread packing ring.
Embodiment
With embodiment, the utility model is described in further detail below, is not practical range of the present utility model is limited to this.
As shown in Figure 1, a kind of stop valve of improvement, comprise copper sleeve body 1, copper sleeve body 1 internal upper part is provided with button 2, button 2 lower end is provided with grip assembly, shell fragment 3 is provided with between button 2 and grip assembly, described grip assembly lower end is provided with spool 4, spring 5 is provided with in the middle part of spool 4 and between grip assembly, spool packing ring 6 is provided with between spool 4 lower end and grip assembly, the utility model by being provided with spring 5 in the middle part of spool 4 and between grip assembly, such spool 4 vent is once large, throughput after ventilation uses also can be thereupon once large, Component quantity reduces, eliminate original spool 4 and spool 4 O type circles, packaging technology becomes simple, substantially increase manufacturing efficiency.
In the present embodiment, described grip assembly comprises the upper grip assembly 7 being located at shell fragment 3 lower end, upper grip assembly 7 top is provided with taper hole, upper grip assembly 7 bottom is provided with bulge loop, upper grip assembly 7 lower end is connected with lower grip assembly 8, lower grip assembly 8 inwall offers the groove be connected with bulge loop, lower grip assembly 8 lower end offers scrobicular ring, wherein, the stepped guard ring in cross section 9 is provided with between described button 2 and copper sleeve body 1, described copper sleeve body 1 bottom is provided with outside thread packing ring 10, guard ring 9 bottom and upper grip assembly 7 are connected, such connection is tight, during use, with the spool 4 after designs simplification, spring 5 with the use of, make spool 4 vent once large, throughput after ventilation uses also can be thereupon once large.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
