For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of soft seal stop valve, is effectively reduced the wearing and tearing of flap and valve base chamber by soft contact, improve sealability, and valve seat can be changed, and improves working life.
For achieving the above object, the utility model provides following technological scheme: a kind of soft seal stop valve, comprise valve body, valve gap, valve rod, flap, valve seat and handwheel, described valve seat is cylindric and is threadedly connected to the runner mouth of valve body, described valve seat is provided with elasitic layer for the part abutting flap, the inner passage of described valve seat comprises circular channel and interior hexagonal channels, circular channel is positioned at the side near flap place, and the circumcircle diameter of interior hexagonal channels is less than or equal to the diameter of circular channel.
Described valve seat is provided with the spacing flange contacting at runner mouth edge relative to one end of flap, the other end of the relative flap of runner mouth is provided with and forms the limited part of conflicting with the end of valve seat.
The end face that described spacing flange is used for the other end of side and the relative flap of valve seat of conflicting with runner mouth edge is equipped with annular caulking groove, described elasitic layer is the rubber bush that both ends open place is equipped with embedding part, and rubber bush is fixed on the inwall of valve seat by the embedding part at two ends being embedded laminating in two caulking grooves.
The tapered structure of the part that described flap contacts with valve seat, described valve seat is provided with the taper mouth with flap adaptation.
Effect of the present utility model is, valve seat has abandoned traditional welding in the mode of runner mouth, by valve seat being set to cylindrical shape and being threadedly connected to runner mouth, valve seat can be dismantled, and the inside of valve seat is provided with interior hexagonal channels, by the parts such as valve gap and valve rod are split out during replacing, adopt hexagon wrench to insert in interior hexagonal channels valve seat is produced, convenient laborsaving, the circumcircle diameter of interior hexagonal channels is less than or equal to the diameter of circular channel, to ensure that hexagon wrench can insert interior hexagonal channels and be formed with interior hexagonal channels and coordinate.And valve seat is used for being provided with elasitic layer with the part of valve flap contacts, elasitic layer and flap is utilized to form soft contact, the wearing and tearing of effective reduction flap and valve base chamber, thus improve flap and contact the sealing formed with valve seat, even if when elasitic layer wear extent is larger, also by valve seat is split out, elasitic layer is changed, effectively improve the working life of this stop valve.

Embodiment
Referring to figs. 1 through Fig. 6, the utility model soft seal stop valve embodiment is described further.
Soft seal stop valve described in the utility model, as shown in Figure 1, comprise valve body 1, valve gap 2, valve rod 3, flap 4, valve seat 5 and handwheel 7, described valve seat 5 is cylindric and is threadedly connected to the runner mouth 11 of valve body 1, described valve seat 5 is provided with elasitic layer for the part abutting flap 4, the inner passage of described valve seat 5 comprises circular channel 51 and interior hexagonal channels 52, circular channel 51 is positioned at the side near flap 4 place, and the circumcircle diameter of interior hexagonal channels 52 is less than or equal to the diameter of circular channel 51.
Effect of the present utility model is, valve seat 5 has abandoned traditional welding in the mode of runner mouth 11, by valve seat 5 being set to cylindrical shape and being threadedly connected to runner mouth 11, valve seat 5 can be dismantled, and the inside of valve seat 5 is provided with interior hexagonal channels 52, by the parts such as valve gap 2 and valve rod 3 are split out during replacing, adopt hexagon wrench to insert in interior hexagonal channels 52 valve seat 5 is produced, convenient laborsaving, the circumcircle diameter of interior hexagonal channels 52 is less than or equal to the diameter of circular channel 51, to ensure that hexagon wrench can insert interior hexagonal channels 52 and be formed with interior hexagonal channels 52 and coordinate.And valve seat 5 is provided with elasitic layer for the part contacted with flap 4, elasitic layer and flap 4 is utilized to form soft contact, wearing and tearing between effective reduction flap 4 and valve seat 5, thus improve flap 4 and contact with valve seat 5 sealing formed, even if when elasitic layer wear extent is larger, also by valve seat 5 is split out, elasitic layer is changed, effectively improve the working life of this stop valve.
Further, with reference to shown in Fig. 3, one end of the relative flap 4 of described valve seat 5 is provided with the spacing flange 53 contacting at runner mouth 11 edge, and the other end of the relative flap 4 of runner mouth 11 is provided with the limited part 12 being formed with the end of valve seat 5 and conflict.The spacing flange 53 arranged and limited part 12 more flange valve seat 5 rotate in place.
