It connects.
It is further improved, the connector welds together with valve body, and connection is firm.
It is further improved, the rubber valve seat is provided with the groove coordinated with connector close to the side of valve interior wall.By
In rubber due to elasticity, so rubber valve, then be set in by the size of the groove slightly lower correspondingly-sized with connector by groove
After on connector, since the restoring force of rubber acts on, the inner wall of groove and the surface of connector tightly suit, very firm, no
It is easy to fall off.
It is further improved, the cavity in the rubber valve seat is opened up along ring-shaped rubber valve seat, and cavity is ring-type, ensures valve
After seat inflation, the inner peripheral surface of valve seat can be with the edge seal of valve plate.
It is further improved, the inflating port, leakage port are opened in rubber valve seat on the side wall of valve body, on body wall
Through-hole there are two opening up, inflating port, leakage port connect respectively with a through-hole.By opening up through-hole on body wall to valve seat
It being inflated and loses heart, space is unrestricted, easy to operate, and the inner wall of valve seat groove and the surface of connector tightly suit,
Will not the gas leakage between valve body and valve seat, good airproof performance.
Compared with prior art, the beneficial effects of the utility model are：
Valve seat is made of rubber, is installed with valve body, and valve base cavity can be inflated, and has inflating port, leakage port outside valve body.When
When valve is opened, first lose heart, valve plate is detached with valve seat, no friction, then valve plate Unscrew.When the valve is closed, it first rotates
Valve rod closes valve plate, and then reinflated, valve seat is heaved, the EDGE CONTACT with valve plate, and then seals.Valve seat is made of rubber,
For soft seal, abrasion of the solid matter to valve seat, and good airproof performance are reduced.
Description of the drawings
Fig. 1 is the structure diagram for the butterfly valve that valve seat described in the utility model is inflatable.
Fig. 2 is the A-A sectional views of Fig. 1.
Specific embodiment
To make the purpose of this utility model and technical solution clearer, below in conjunction with the utility model embodiment to this
The technical solution of utility model is clearly and completely described.
As shown in Figure 1, 2, a kind of valve seat is the butterfly valve of inflatable, including actuator 5, valve body 1, valve rod 2 and valve plate 3, institute
It states valve interior wall and is circumferentially fixedly installed ring-shaped rubber valve seat 4, the inside of rubber valve seat 4 offers cavity 9, on rubber valve seat
Inflating port and leakage port are provided with, inflating port, leakage port are connected with the cavity 9 of rubber valve seat.
Valve seat is made of rubber, is installed with valve body, and valve base cavity can be inflated, and has inflating port, leakage port outside valve body.When
