A kind of dome-type valve head non-return valve, including valve body and spool, the valve inner be equipped with spool cooperation in
Chamber, the spool include dome-type plug, newel, annular table and elastic component, and dome-type plug and newel one end are removable
It unloads and is fixedly connected, the newel other end is socketed annular table, and elastic component is socketed on annular table, and one end of elastic component is connected to annular table
End, elastic component are set between dome-type plug and annular table, and the inner cavity is equipped with the angle cooperated with dome-type plug, partly
The sphere end of ball-type plug is connected to edge in angle.By above technical scheme, the spherical surface of dome-type plug and body cavity
Angle connect it is closed be closed valve, when elastic component compression cause newel opposed annular platform generate shaking, to make dome-type
When plug generates displacement, the spherical surface of dome-type plug still can connect with angle keeps closed, maintains the tight close shape of valve
State.
Preferably, the dome-type plug is the hemisphere made of elastic material.Elastic material includes but unlimited
In rubber, elastoplastic, silica gel etc., hemisphere made of elastic material keeps it closed with being bonded for angle.
Preferably, the planar ends of the dome-type plug are equipped with cavity, cavity is protruded into newel one end end, described
Cavity inside be equipped with locating slot, newel one end end is equipped with chimb for cooperating with locating slot.The effect of cavity is to make
Dome-type plug and newel are convenient for disassembly and assembly.
Preferably, one end end that the newel is connect with dome-type plug is equipped with the gear for stopping elastic component
Piece, elastic component one end are connected to baffle.
Preferably, the newel one end end opposite with dome-type plug is equipped with the gear for stopping annular table
Side.
Preferably, the annular table includes outer ring, dowel and the central tube that ecto-entad is set gradually, central tube
Length be greater than the length of outer ring, central tube is fixedly connected with outer ring by dowel, and elastic component is socketed on central tube outer surface, in
Heart cylinder outer diameter is slightly less than elastic component internal diameter.
Preferably, the elastic component is spring.
The beneficial effects of the utility model are:
The dome-type valve head check valve arrangement of the utility model is simple, easy to assembly, valve closure accuracy is high, elastic component and
The cooperation of annular table is opened and closed dome-type plug accurately under guiding role, and spool is avoided to deviate valve axis, and dome-type
Plug connect with the angle of body cavity it is closed, even if when newel slight displacement causes dome-type plug change in location, still
The airtightness that can guarantee dome-type plug and angle maintains the tight close state of valve.
