Description
Technical field
The present invention relates to a kind of drain valves, and in particular to a kind of safety drain valve of drainage pipeline.
Background technology
A valve generally can be all arranged in draining in drainpipe, and the type of valve has very much, but due to drainpipe one
As be all made of PVC material, therefore valve closing after, larger hydraulic pressure can squeeze pipe outer wall, apply pressure to water for a long time
Tube wall causes large effect, eventually leads to the explosion of water pipe.
In addition, traditional drain valve is complicated, the structure of water pipe can be increased after being installed on pipeline, feed pipe causes
Pressure, buying the cost of valve also can accordingly increase.
Invention content
Technical problem to be solved by the invention is to provide a kind of safety drain valves of drainage pipeline, simple using one
Structure can effectively reduce influence of the hydraulic pressure to closing after closing, increase cushion performance, and then increase the service life of pipeline.
The present invention is achieved through the following technical solutions：A kind of safety drain valve of drainage pipeline, including first is close
Block plate and the second sealing web plate, the first sealing web plate is set to the upper end of the second sealing web plate, and both seals
It is installed in pipeline, is provided with more than one first osculum on the first sealing web plate, described second seals on web plate
There are one the second above osculums with the first osculum stagger setting, and there are one water storages for the interior setting of the second sealing web plate
Chamber, water storage cavity top each first osculum of face are both provided with an apopore, and apopore is rubber diaphragm sealed by one, pipeline
It is external a pusher is installed, extra water is pushed into water storage cavity by pusher.
The pusher includes that a push is managed as a preferred technical solution, and one push chamber of setting, pushes away in push pipe
Intracavitary is sent to store water, a piston is arranged in push intracavitary, and a push rod is arranged in the top of piston, and the output for pushing chamber terminates a water delivery
Pipe, the output end of water-supply-pipe are connect with the water inlet in the second sealing net board bottom portion.
The outer wall of the first sealing web plate and the second sealing web plate is both provided with a circle as a preferred technical solution,
Above card slot, a circle sealing ring is wrapped up in card slot, and the first sealing web plate and the second sealing web plate are close by sealing ring
Envelope is installed in pipeline.
The water-supply-pipe passes through a side through hole of pipeline as a preferred technical solution, and a water proof ring is packed into the through-hole,
The water-supply-pipe passes through the sealing hole among water proof ring.
A clearance layer is formed between the first sealing web plate and the second sealing web plate as a preferred technical solution,
The rubber membrane heaved is heaved and seals first osculum at top.
The beneficial effects of the invention are as follows：The present invention uses a simple valve body, realizes the switch to pipeline, and after closing
Influence of the hydraulic pressure to closing can be effectively reduced, increases cushion performance, and then increase the service life of pipeline.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the usage state diagram of the present invention.
Coding in figure is respectively：1 is osculum, and 3 be sealing ring, and 4 be water storage cavity, and 5 be the second sealing web plate, and 6 be the
Two osculums, 7 be water proof ring, and 8 be water-supply-pipe, and 9 be push pipe, and 11 be rubber membrane, and 12 be piston, and 13 be push rod, and 14 be push
Chamber, 15 be the first sealing web plate.
Specific implementation mode
As shown in Figure 1, the safety drain valve of this drainage pipeline, including the first sealing web plate 15 and second seal web plate 5,
First sealing web plate 15 is set to the upper end of the second sealing web plate 5, and is both seal-installed in pipeline, the first sealing web plate
Be provided with more than one first osculum 1 on 15, on the second sealing web plate 5 with 1 stagger setting of the first osculum there are one with
On the second osculum 6, setting is there are one water storage cavity 4 in the second sealing web plate 5, each first draining of 4 top face of water storage cavity
Hole 1 is both provided with an apopore, and apopore is sealed by a rubber membrane 11, and the external of pipeline installs a pusher, push
Extra water is pushed into water storage cavity 4 by device.
Wherein, pusher includes a push pipe 9, and push pipe 9 is interior to be arranged a push chamber 14, is stored in push chamber 14
Water, push chamber 14 is interior to be arranged a piston 12, and a push rod 13 is arranged in the top of piston 12, and the output of push chamber 14 terminates a water-supply-pipe
8, the output end of water-supply-pipe 8 is connect with the water inlet in the second sealing net board bottom portion.
The outer wall that first sealing web plate 15 and second seals web plate 5 is both provided with the card slot of a circle or more, in card slot
One circle sealing ring 3 of package, the first sealing web plate 15 and second seal web plate 5 and are seal-installed in pipeline by sealing ring 3.
First sealing web plate 15 and second, which seals web plate 5, to be conveniently mounted inside pipeline, sealing ring very convenient installing
The structure of dimpling can be used, more fastened after the completion of assembly in this way.
Wherein, water-supply-pipe 8 passes through a side through hole of pipeline, and a water proof ring 7 is packed into the through-hole, and water-supply-pipe 8 passes through waterproof
The case where enclosing intermediate sealing hole, increasing the leakproofness at water-supply-pipe, prevent leak.
As shown in Fig. 2, the first sealing web plate 15 and second forms a clearance layer, the rubber heaved between sealing web plate 5
As long as film 11 is heaved and seals first osculum at top, using push rod, the water for pushing intracavitary to be pushed away when needing to close pipeline
It is fed into the water storage cavity in the second sealing web plate, does not have Packed first osculum to pass through the rubber membrane of protrusion originally at this time
Sealing, just can not achieve draining, water impact plays the purpose of buffering on rubber membrane at this time；When proper drainage, as long as taking out
Go out the water in water storage cavity so that rubber membrane is not heaved, so i.e. using first row water hole and the second water drainage.
The beneficial effects of the invention are as follows：The present invention uses a simple valve body, realizes the switch to pipeline, and after closing
Influence of the hydraulic pressure to closing can be effectively reduced, increases cushion performance, and then increase the service life of pipeline.
