Pipeline after the valve of road；The muddy water pipeline includes pipeline after muddy water valve preceding pipeline and muddy water valve；The valve plate core is in the sliding axle
It holds and rotates to realize that waterway pipe, muddy water pipeline penetrate through respectively or pipeline cleaning penetrates through.
Further, the valve plate core is placed and seal groove is equipped at sealing element, and the sealing element is y-type seal ring.
Further, the cross section of the y-type seal ring is asymmetrical Y-type, and the y-type seal ring is close to the above, the lower lid
The long end of side will be longer than short end.
Further, the opening of the y-type seal ring is outwardly.
Further, the rotation of the valve plate core is driven by pneumatic mode.
Further, the internal diameter of the waterway pipe is less than the internal diameter of muddy water pipeline.
Further, pipeline is equipped with pressure inductor after the water route valve preceding pipeline, the muddy water valve.
The utility model has the advantages that：
1. it is not easy to plug, easy cleaning, during normal work, waterway pipe and the perforation of muddy water pipeline, that is to say, that waterway pipe
By being connected to muddy water storehouse after by-passing valve, by water input muddy water storehouse, the size of slag charge is effectively reduced, then water carries slag charge
Into muddy water pipeline, so as to be discharged outside to；When muddy water pipeline blocks, rotary valve plate core, the water in waterway pipe at this time
Road valve preceding pipeline is penetrated through with pipeline after the muddy water valve in muddy water pipeline, is rinsed with water pipeline, dredging pipeline.
2. good airproof performance equipped with asymmetrical Y-type sealing ring, effectively improves the sealing performance of by-passing valve, extends by-passing valve
Service life.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the vertical view of Fig. 1；
Fig. 3 is the structure diagram that I amplifies in Fig. 1.
Specific embodiment
In order to better understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Push-bench by-passing valve, including valve body, bolt, sealing element 7, upper cover plate 3, sliding bearing 6, valve plate core 5, lower cover
4, the sliding bearing 6 is fixed at the above, the lower lid, and the both ends of the valve plate core 5 are fixed in the above, the lower lid and pass through and slide
Bearing 6, the valve plate core 5 can rotate in the sliding bearing 6, the valve plate core 5 and the valve body fit inside, the valve
Plate core 5 and the above, the lower lid contact jaw are equipped with sealing element 7, further include waterway pipe, muddy water pipeline, the waterway pipe with
The muddy water pipeline is arranged in parallel, and the waterway pipe includes pipeline 12 after water route valve preceding pipeline 11 and water route valve；The muddy water
Pipeline includes pipeline 22 after muddy water valve preceding pipeline 21 and muddy water valve；The valve plate core 5 rotates to realize water in the sliding bearing 6
Road pipeline, muddy water pipeline penetrate through respectively or pipeline cleaning perforation.
The valve plate core 5 is placed and seal groove is equipped at sealing element 7, and the sealing 7 is y-type seal ring；The Y types sealing
The cross section of circle is asymmetrical Y-type, and the y-type seal ring will be longer than short end 71 close to the long end 72 of the above, the lower lid side；The Y
The opening of type sealing ring is outwardly.The long end 72 of the y-type seal ring be conducive to the above, the lower lid tight seal, and close to valve plate
The short end 71 of core due to the presence of seal groove, can form good sealing, without lengthening.It should be noted that sealing element 7
O-ring can also be used.
The rotation of the valve plate core 5 is driven by electrical flowing mode.It should be noted that do not limit electro-pneumatic driving herein,
