Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of integral type butterfly valve check-valves loose joint structure, including
Butterfly valve 100, check-valves 101, eccentric joint 102 and limited block 104,100 side wall of butterfly valve are flexibly connected by loose joint structure
There is check-valves 101, the check-valves 101 is connected with eccentric joint 102,101, the check-valves far from the fixation of 100 one end of butterfly valve
It is connected to rubber seal 107 in 102 inside one end outer surface fixing sleeve of eccentric joint, 101 outer surface of check-valves is located at rubber
Glue sealing ring side offers limiting slot 110, and 102 inside of eccentric joint offers card slot outside limiting slot 110
106,106 internal activity of card slot is connected with steel band 105, and the steel band 105 is welded with close to 101 water inlet side of check-valves
Limited block 104, the 102 outer surface side wall of eccentric joint are fixedly welded with rotation seat 108, and 108 side of rotation seat passes through
Shaft is rotatably equipped with lock handle 109, and 100 side wall of butterfly valve is connected far from 101 side of check-valves by loose joint structure activity
It is connected to water outlet 103.
105 two movable ends of the steel band pass through shaft respectively and are rotatably installed in 109 two corner points of lock handle, when turn
When dynamic lock handle 109, when lock handle 109 rotates around the axis, corner point can generate certain displacement, by the two of steel band 105
Movable end is pulled outwardly simultaneously, is caught in limited block 104 in limiting slot 110, guarantees that eccentric joint 102 is socketed on valve not
It can fall off；Lockable mechanism is installed between the lock handle 109 and rotation seat 108, when eccentric joint 102 is fixedly attached to valve
After on gate valve body, by lockable mechanism locking lock handle 109, prevent the reset of lock handle 109 from causing eccentric joint 102 de-
It falls；102 inside of eccentric joint offers the groove agreed with 107 phase of rubber seal on the outside of rubber seal 107,
After 102 fix in position of eccentric joint, rubber seal 107 just enters inside grooves, prevents rubber seal 107 from generating position
It moves, sealing effect is caused to be deteriorated；Rubber seal is provided between the butterfly valve 100 and check-valves 101, water outlet 103
107, it is ensured that be fully sealed between valve and between valve and pipeline, prevent seam crossing from revealing.
Eccentric joint 102: in use, lock handle 109 is loosened, being socketed in the water inlet of valve by working principle,
After limited block 104 is aligned limiting slot 110, rotation lock handle 109, when lock handle 109 rotates around the axis, corner point can be produced
Raw certain displacement, two movable ends of steel band 105 are pulled outwardly simultaneously, make being caught in limiting slot 110 tightly of limited block 104,
Guaranteeing that eccentric joint 102 is socketed on valve will not fall off, and can prevent the reset of lock handle 109 from causing by lockable mechanism
Eccentric joint 102 falls off, and the center line of pipe centerline and valve is encountered when construction not in collinear special circumstances,
By rotating eccentric joint 109, so that 109 other end of eccentric joint is moved closer to the center line of valve body, until consistent, then pass through work
Eccentric joint 109 is socketed on valve body by binding structure, can solve the center line of pipe centerline and valve not collinear
Problem.
