Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Secondly; the utility model is described in detail in conjunction with schematic diagram; when describing the utility model embodiment in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.In addition, the three-dimensional space of length, width and height should be comprised in actual fabrication.
As shown in Figure 1 to Figure 3, the utility model comprises keying valve body 1, the top of described valve body 1 is communicated with venting gas appliance 2, described venting gas appliance comprises exhaust cavity 21, floating drum 22 and sealer, described exhaust cavity 21 is communicated with described valve body 1 inside, and described exhaust cavity 21 top is provided with relief opening, and described sealer seals relief opening, it is inner that described floating drum 22 is arranged on described exhaust cavity 21, is connected with described sealer.Described keying valve is gate valve.
Be connected with one end of connecting rod above described floating drum 22, the other end of described connecting rod is connected with the bottom of described sealer, described sealer comprises sealed support 23, recovery device 24 and the sealing seat 25 with central through bore, the lower end of described sealed support 23 is connected with lever, its upper end is flexibly connected with described sealing seat 25 by recovery device 24, and described sealed support 23 can be sealed from lower end the central through bore of described sealing seat 25 by sealing gasket.
Described recovery device 24 is jump ring, and described sealing seat 25 is provided with jump ring support, and the both sides of described jump ring support are connected with the two ends of jump ring respectively, and the middle part of described jump ring is socketed on described sealed support 23.
