Fig. 3 is the sectional view of B-B in Fig. 1;
In figure, the annulus, 15 of 1 be valve body, 2 be valve rod, 3 be spring, 4 be seal ring, 5 be pad, 6 be pressure cap, 7 be sleeve, 8 be screw, 11 be handle hole, 12 be inlet hole, 13 to be air outlet hole, 14 be evagination is the annulus, 16 of convex is annular groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
An extinguisher valve door device as shown in Figure 1-Figure 3, comprises valve body 1, valve rod 2, spring 3, seal ring 4 and pad 5; Described valve body 1 includes about two connections and the handle hole 11 of longitudinal direction is communicated with and the air outlet hole 13 of transverse direction with inlet hole 12 with one with inlet hole 12; The two ends up and down of described valve rod 2 lay respectively at handle hole 11 with in inlet hole 12, described handle hole 11 is provided with one and is tightly connected with it and material is the sleeve 7 of plastics, the two ends up and down of described sleeve 7 are respectively arranged with the annulus 14,15 of evagination and convex, the annulus 14 of described evagination is positioned at the end face of valve body 1, the end face of described valve body 1 is provided with an annular groove 16 coaxial with handle hole 11, is provided with one and seals with the annulus 14 of evagination the seal ring 4 contacted in described annular groove 16.The annulus 14 of described evagination includes the uniform screw 8 of several annulars, and described screw 8 is connected with valve body 1, and described valve rod 2 is plugged in sleeve 7.Described seal ring 4, pad 5 and spring 3 are all socketed in top valve rod 2 being also placed on successively step, and the top of described valve rod 2 is provided with a pressure cap 6, and the axial two ends of described spring 3 contact with pressure cap 6 with pad 5 respectively.
The top of described valve body 1 is also provided with one and contacts with pressure cap 6 and to control the handle 9 that pressure cap 6 presses down, thus controls gas flow.
Time in the locked state, the spool bottom described valve rod 2 is sealed, so can prevent gas flow by the pressure of spring 3 and inlet hole 12.When using state, described handle 9 is with ovable valve stem 2 to press down, then the spool bottom valve rod 2 is separated with inlet hole 12, and can valve rod 2 and sleeve 7 be sealed pad 5 times pressure seal rings 4 by seal ring 4 after spring 3 compresses, thus air-flow can not flow in sleeve 7, also can not contact spring 3, and spring 3 is also positioned at handle hole 11 place, so the flow effect of air-flow is very good.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
