Technical scheme：For achieving the above object, the present invention is adopted the following technical scheme that：
Duplex triple valve, including valve body, the valve body are made up of the triple valve of two interconnections, and each triple valve is respectively
Including a triple valve inlet and two threeway valve outlets；Two described triple valves be fixed on axle and each other by every
Plate separates, and dividing plate is set on axle by support；Valve body cover plate is respectively provided with the upper and lower ends of described valve body, in valve
The valve body cover plate on body top is provided with the bonnet for sealing, be provided with for fixed in the bottom of the valve body cover plate of valve body lower portion and
The valve back seat cover plate of sealing；Two pairs of valve board assemblies for coordinating two triple valve inlets to use, valve are respectively equipped with described axle
Board component includes guide rail, seal, connecting rod and set screw；The handle for drive shaft is provided with one end of described axle；
It is provided between two valve board assemblies inside each triple valve and moves left and right the cam for completing sealing for drive valve plate component；
The dovetail sealing ring for sealing is equipped with described valve board assembly.
Sealed by O-ring between described dividing plate and axle, by adjusting washer sealing between support set and axle.
Described handle is fixed by handle set, and handle set is fixed on valve body by locking pin, and handle set passes through cylinder
Direct selling is fixed on axle.
Described bonnet is fixed on valve body by hex nut.
The hole of fixing axle is respectively reserved with described bonnet and valve back seat cover plate；Between described axle and bonnet
Adjustment packing ring is provided with, adjustment packing ring is provided between described axle and valve back seat cover plate.
It is connected by soket head cap screw between described cam and axle.
Described O-ring and dovetail sealing ring is nitrile rubber material.
The locking pin for positioning cam position is provided with described handle set, is provided with what is used cooperatively on locking pin
Locking pin spring.
Beneficial effect：Compared with prior art, duplex triple valve of the invention, two are controlled by using a handle simultaneously
Individual triple valve inlet, improves operating efficiency, while using sealing means such as dovetail sealing rings, overcome tradition machinery sealing and
The defect of abrasion that O-shaped washer sealing brings and leakage is used uniformly across, the perfect sealing of duplex triple valve is realized, it is prolonged resistance to
With, and the application duplex triple valve simple structure, it is compact, install easy maintenance, seal it is relatively reliable, the equipment of extending makes
With the life-span, it is easy to care and maintenance, possesses good practicality.
Brief description of the drawings
Fig. 1 is the front view of duplex triple valve；
Fig. 2 is the side view of duplex triple valve.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the parts on valve body include handle 1, bonnet 2, valve body 3, flange 4, dividing plate 5, valve
It is board component 6, valve body cover plate 7, valve back seat cover plate 8, soket head cap screw 9, hex bolts 10, O-ring 11, dovetail sealing ring 12, convex
Wheel 13, axle 14, support set 15, adjustment packing ring 16, triple valve inlet 17, cylinder sell 18, handle set 19, locking pin 20, hexagonal directly to households
Nut 21.
Duplex triple valve includes valve body 3, and valve body 3 is made up of the triple valve of two interconnections, and two triple valves are fixed on
Separate on axle 14 and each other by dividing plate 5, valve body cover plate 7 is respectively provided with the upper and lower ends of valve body, on valve body top
Valve body cover plate 7 be provided with bonnet 2 for sealing, be provided with for fixed and close in the bottom of the valve body cover plate 7 of valve body lower portion
The valve back seat cover plate 8 of envelope.Each triple valve respectively includes three valve components, three valve components one of them be triple valve
Entrance 17, another two is threeway valve outlet.Flange 4 is equipped with three valve components.
Two pairs of valve board assemblies 6 for coordinating two triple valve inlets 17 to use are respectively equipped with axle 14, valve board assembly 6 includes
Guide rail, seal, connecting rod and set screw.The handle 1 for drive shaft 14 is provided with one end of axle 14, by the drive of handle 1
The rotation of dynamic drive valve board assembly 6, the keying for completing triple valve inlet 17 is moved left and right by valve board assembly 6.Each pair valve plate
The cam 13 for drive connection is provided between component 6.The dovetail sealing ring for sealing is equipped with each valve board assembly 6
12, herein using dovetail sealing ring 12 because because external pressure is big, and the inner small and outside big size of dovetail sealing ring 12, can
Press tighter and tighter in the presence of external pressure, the situation without producing all kinds of gasket wears in conventional seals mode.
Dividing plate 5 is arranged on axle 14 by support set 15, is sealed by O-ring 11 between dividing plate 5 and axle 14, support set 15
Sealed by adjusting packing ring 16 and axle 14 between.
