The big industrial pipeline valve that 10m is reached to latus rectum of gauge valve.Available for control water, steam, oil product, gas, mud, various corrosion
The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow, and the operating pressure of valve can be from 0.0013MPa
To 1000MPa super-pressure, operating temperature can be with c-270 DEG C of ultralow temperature to 1430 DEG C of high temperature.
The control of valve can use a variety of kinds of drive, such as manually, electrically, surge, pneumatic, turbine, electromagnetic driven, electromagnetic liquid
Dynamic, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear driving etc.；Can pressure, temperature or other forms transducing signal effect
Under, acted by predetermined requirement, or be simply turned on and off independent of transducing signal, valve is by driving or certainly
Motivation structure lifts opening and closing element, slid, swing or gyration, so as to change the size of its flow area to realize that its is controlled
Function.
In the application of valve, sealing gasket is one of its essential accessory used, now all kinds of sealings on the market
Pad species a lot, but it is most of all there is use time length after, sealing effectiveness declines, or can not realize sealing function,
Service life is short, and for the difficult valve of some handling, it is highly difficult thing to change sealing gasket, is badly in need of solving this now
Problem.
Utility model content

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of V-type filler group sealing gasket, including sealing gasket main body 10, it is close
Packing main body 10 is made up of upper Packing seat 7, intermediate filler pad 8 and lower Packing seat 9, and bullet is housed in upper Packing seat 7 and lower Packing seat 9
Spring packing ring 5, the upper outer ring upper end of Packing seat 7 and the outer ring lower end of lower Packing seat 9 are equipped with rubber washer 4, and the upper lower end of Packing seat 7 is V
