Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description：
As depicted in figs. 1 and 2, the gasket seal of fire hydrant of the present utility model, including ring flange washer portion and valve pad
Circle portion, valve washer portion is arranged at ring flange washer portion center, and ring flange washer portion is integrally formed with valve washer portion and is connected.Method
Blue dish washer portion is located between ring flange for pad, makes waterstop sealing between ring flange.Valve washer portion is used to pad in valve port
Place, makes waterstop sealing between valve port and blocking piece.
Ring flange washer portion be symmetrically arranged with the bolt hole corresponding with the bolt hole of matched somebody with somebody ring flange and with setting
The corresponding sluicing intercommunicating pore of fire hydrant drainage gallery at matched somebody with somebody ring flange.When being bolted lock flange disk,
Bolt need to be Jing Guo ring flange washer portion bolt hole, and then the position in lock flange dish washer portion.Fire hydrant drainage gallery is
The water being trapped in after fire hydrant in key is used for chip removal.Both side surface above and below sluicing intercommunicating pore connection flange dish washer portion,
Sluicing intercommunicating pore is corresponding with the drainage gallery being located at ring flange of matched somebody with somebody fire hydrant, and drainage gallery sequentially passes through key bottom
Ring flange and top end of the valve body ring flange sluice downwards, so ring flange washer portion sets corresponding sluicing intercommunicating pore, for connecting
The drainage gallery at drainage gallery and top end of the valve body ring flange at the ring flange of key bottom.
Valve washer portion include air ring and tube-shaped pad, air ring be arranged at ring flange washer portion center and with flange plate mat
Circle portion is integrally formed connection, and tube-shaped pad is vertically installed in air ring center and is integrally formed with air ring and is connected.Air ring center
Interior collar extension is provided with, tube-shaped pad center is provided with tube chamber, and the interior collar extension of air ring is connected with the tube chamber of tube-shaped pad.Open valve
When, current sequentially pass through interior collar extension and tube chamber is flowed into key, are then outwards supplied water from the feed water inlet of key.Air ring is provided with
Connect the water pressure passage hole of both side surface above and below air ring, water pressure passage hole and the hydraulic pressure Acquisition channel for matching somebody with somebody hydrant pressure table
Entrance it is corresponding.Water pressure gauge is arranged on key sidepiece, and hydraulic pressure Acquisition channel is arranged in key inwall, and air ring sets hydraulic pressure
Access opening, makes the hydraulic pressure in valve body be transmitted to from water pressure passage hole in hydraulic pressure Acquisition channel, and then is transmitted to water pressure gauge display water
Pressure.The external diameter of tube-shaped pad is adapted with the valve port internal diameter of matched somebody with somebody valve.Tube-shaped pad is socketed in valve port, is not only padded in valve
Intraoral wall, and be fixed in valve port, it is possible to reduce the displacement and deformation of air ring, reduce blocking piece and are directly connect with valve port
Touch, and then improve the sealing of valve.
