For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of extinguisher valve door, comprises valve body, valve rod, spring and annular soft pad; Described valve body includes about two connections and the handle hole of longitudinal direction is communicated with and the air outlet hole of transverse direction with inlet hole with one with inlet hole; The two ends up and down of described valve rod lay respectively in handle hole and inlet hole, described handle hole includes a step be socketed on valve rod, described spring housing to be connected on valve rod and to be placed on step, the top of described valve rod is provided with a pressure cap, and the axial two ends of described spring contact with pressure cap with step respectively; Described annular soft pad to be positioned on valve rod and to be arranged on the end face of valve body, and its endoporus is connected with valve seal with pressure cap respectively with outer edge.
In above-mentioned extinguisher valve door, also comprise the first pressure ring and the first nut; Described first pressure ring and the first nut are socketed on pressure cap successively, and described first pressure ring is positioned at the top of annular soft pad, and described first nut to move as spiral relative to pressure cap and annular soft pad sealed with pressure cap contact.
In above-mentioned extinguisher valve door, also comprise the second pressure ring and the second nut; Described second pressure ring is positioned at the top of annular soft pad, described second nut be positioned at annular soft pad top and relatively valve body do in rotary movingly to make annular soft pad and valve body contact.
In above-mentioned extinguisher valve door, the material of described annular soft pad is silica gel.
In above-mentioned extinguisher valve door, also comprise and be socketed in pad on valve rod and seal ring, described seal ring and pad are successively set on step, its medi-spring and pad contacts.
(3) beneficial effect
Extinguisher valve door of the present utility model, by arranging the annular soft pad of a silica gel material, make annular soft pad by the gap sealing between handle hole and valve rod, from then on such air-flow can not flow out in gap, and it also avoid ring wear in conventional art and wear and tear in moving process and cause the phenomenon of gas leakage, extend working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of extinguisher valve door of the present utility model;
Fig. 2 is the enlarged view of A in Fig. 1;
Fig. 3 is the structural representation of the extinguisher valve door of prior art;
1 be valve body in figure, 2 be valve rod, 3 be spring, 4 be annular soft pad, 6 be handle hole for pressure cap, 7 be the first pressure ring, 8 be the first nut, 9 be the second pressure ring, 10 is the second nut, 11,12 be inlet hole, 13 be air outlet hole, 14 be step, 15 be pad, 16 be seal ring.
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 as depicted in figs. 1 and 2, comprises the annular soft pad 4 of valve body 1, valve rod 2, spring 3 and silica gel material; 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 includes a step 14 be socketed on valve rod 2, described spring 3 to be socketed on valve rod 2 and to be placed on step 14, 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 step 14 respectively; Described annular soft pad 4 to be positioned on valve rod 2 and to be arranged on the end face of valve body 1, and its endoporus and outer edge are tightly connected with pressure cap 6 and valve body 1 respectively.By arranging the annular soft pad 4 of a silica gel material, make annular soft pad 4 by the gap sealing between handle hole 11 and valve rod 2, from then on such air-flow can not flow out in gap, and it also avoid ring wear in conventional art and wear and tear in moving process and cause the phenomenon of gas leakage, extend working life.
Here is the concrete mounting type of annular soft pad 4: the utility model devises the first pressure ring 7 and the first nut 8; Described first pressure ring 7 and the first nut 8 are socketed on pressure cap 6 successively, and described first pressure ring 7 is positioned at the top of annular soft pad 4, and described first nut 8 to move as spiral relative to pressure cap 6 and annular soft pad 4 sealed with pressure cap 6 contact.The utility model devises the second pressure ring 9 and the second nut 10; Described second pressure ring 9 is positioned at the top of annular soft pad 4, described second nut 10 be positioned at annular soft pad 4 top and relatively valve body 1 make the annular soft pad 4 that makes in rotary moving and contact with valve body 1.
In order to further improve sealing effect, this structure also comprises and is socketed in pad 15 on valve rod 2 and seal ring 16, and described seal ring 16 and pad 15 are successively set on step 14, and its medi-spring 3 contacts with pad 15.Mobile gasket 15 can be with when valve rod 2 presses down move down, make seal ring 16 with handle hole 11 and valve rod 2 close contact thus formed to seal.
