Description
Technical Field
The utility model relates to a butterfly valve clack for fire hydrant belongs to butterfly valve clack field for fire hydrant.
Background
All be equipped with the valve structure in the fire hydrant, the closure member of valve can be called valve clack or valve plate, and the butterfly valve clack for current fire hydrant is owing to adopt disc enclosed construction, and at the closure and the in-process of opening, the medium forms openly to erode the valve clack, and the sealing strip of valve clack outer lane can reduce sealing performance after being erodeed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a butterfly valve clack for fire hydrant to solve current butterfly valve clack for fire hydrant owing to adopt disc enclosed construction, at the closure with open the in-process, the medium openly erodees to the valve clack formation, the sealing strip of valve clack outer lane is erodeed the back, can reduce sealing performance's problem.
In order to achieve the above purpose, the present invention is realized by the following technical solution: the butterfly valve clack for the fire hydrant structurally comprises a right valve, a fixed column and a left valve, wherein the right valve is arranged at the right end of the fixed column, the left valve is arranged at the left end of the fixed column, elastic strips embedded in the right valve and the left valve are respectively arranged on the outer sides of the right valve and the left valve, a pressure groove is arranged in each elastic strip, a corresponding water pressure channel is arranged at one end, close to the fixed column, of each pressure groove, and a water pressure inlet communicated with the water pressure channel is formed in the positive end faces of the right valve and the left valve.
Furthermore, the number of the right valve inner water pressure channels is three, and the number of the right valve front end surface and the number of the water pressure inlets communicated with the water pressure channels are three.
Furthermore, the number of the left valve inner water pressure channels is three, and the number of the left valve front end surface and the number of the water pressure inlets communicated with the water pressure channels are three.
Further, the elastic strip is made of a rubber material.
The utility model has the advantages that: the medium scouring surface of the valve clack is provided with a structure for secondary sealing through water pressure, so that the sealing performance of the valve clack is effectively improved.
