The utility model provides a fast check valve that closes's theory of operation as follows:
when using the quick-closing check valve, water firstly enters the valve body 1 through the water inlet end 2, then impacts the valve clack 4, so that the valve clack 4 rotates along the first connecting rod 5, the valve clack 4 is impacted, and then the water can directly flow out through the water outlet end 3.
When the valve body 1 needs to be quickly closed, a worker firstly closes other valves, then the water quantity entering the valve body 1 through the water inlet end 2 begins to be reduced at the position of the valve body 1, and the valve clack 4 begins to rotate downwards due to the fact that the gravity of the valve clack is large and the water pressure is high.
At this moment, the worker can pull the pull rod 64 to enable the arc-shaped plate 66 to leave the first clamping groove 8 and return to the telescopic groove 63, then the second connecting rod 7 can be pushed towards the inside of the valve body 1, the second connecting rod 7 moves inwards, meanwhile, one end of the second connecting rod is clamped in the second clamping groove 42, and then the valve clack 4 can be pushed towards one side along the second clamping groove 42, so that the valve clack 4 is blocked in a channel inside the valve body 1, and water backflow is avoided.
After valve body 1 is closed fast, staff alright stimulate second connecting rod 7, make second connecting rod 7 to the outside removal of valve body 1, move first draw-in groove 8 when second connecting rod 7 and return to fixed block 61 inside after, alright unclamp the pull rod 64 in the hand, the spring 67 that is in compression state always needs to resume deformation to upwards extrude arc 66, make arc 66 block in first draw-in groove 8.
After long-time use, a worker can open the top of the valve body 1, then detach the first connecting rod 5 and the valve clack 4 together, see the abrasion degree of the rubber pad 47, when the rubber pad 47 is seriously abraded, detach the bolt 49 from the fixing rod 4, pull the inserting block 48 out of the mounting groove 45, take the rubber pad 47 down, and replace the inserting block with a new one.
Compared with the prior art, the utility model provides a fast check valve that closes has following beneficial effect:
through pulling pull rod 64, make arc 66 leave first draw-in groove 8, alright remove second connecting rod 7 to valve body 1 inside afterwards, thereby make the one end of second connecting rod 7 get into inside second draw-in groove 42, thereby move valve clack 4 whole downwards, make valve clack 4 with valve body 1 inside stifled, through second connecting rod 7 alright close the check valve fast, avoid the check valve can not close for a long time, influence normal use, also cause the waste of inside fluid simultaneously, simultaneously through fixed subassembly 6 alright restriction second connecting rod 7's position, avoid second connecting rod 7 to influence valve clack 4 and normally open, simultaneously through bolt 49 alright extract plug 48 from mounting groove 45, then what hundred years can relax changes rubber pad 47, avoid long-time use back rubber pad 47 and valve body 1 inner wall wearing and tearing serious, cause valve body 1 leakproofness poor.
