Brief description of the drawings
Fig. 1 is the plan view of duplex three-way valve;
Fig. 2 is the side view of duplex three-way valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As depicted in figs. 1 and 2, the component on valve body comprise handle 1, valve gap 2, valve body 3, flange 4, dividing plate 5, valve board assembly 6, valve body cover plate 7, valve back seat cover plate 8, socket head screw 9, hex head bolt 10, O type circle 11, dovetail seal ring 12, cam 13, axle 14, supporting sleeve 15, adjust packing ring 16, triple valve inlet 17, cylinder direct selling 18, handle set 19, spring bolt 20, hexagon nut 21.
Duplex three-way valve comprises valve body 3, valve body 3 is made up of two interconnective three-way valve, two three-way valve are fixed on axle 14 and each other and separate by dividing plate 5, two ends up and down at valve body are provided with valve body cover plate 7 respectively, on the valve body cover plate 7 on valve body top, be provided with the valve gap 2 for sealing, be provided with in the bottom of the valve body cover plate 7 of valve body lower portion for valve back seat cover plate 8 fixing and sealing.Each three-way valve comprises three valve components respectively, and one of them is triple valve inlet 17 for three valve components, and another two is three-way valve outlet.On three valve components, be equipped with flange 4.
On axle 14, be respectively equipped with two pairs and coordinate two valve board assemblies 6 that triple valve inlet 17 uses, valve board assembly 6 comprises guide rail, Sealing, connecting rod and adjusting screw.Be provided with the handle 1 for live axle 14 in one end of axle 14, drive the rotation of valve board assembly 6 by the driving of handle 1, by the keying that has moved left and right triple valve inlet 17 of valve board assembly 6.Between every pair of valve board assembly 6, be provided with the cam 13 for driving connection.On each valve board assembly 6, be equipped with the dovetail seal ring 12 for sealing, adopt dovetail seal ring 12 to be herein because because external pressure is large, and the inner small and outside big size of dovetail seal ring 12, can be under the effect of external pressure more press tightlyer, and can not produce the situation of all kinds of gasket wear in conventional seals mode.
Dividing plate 5 is arranged on axle 14 by supporting sleeve 15, between dividing plate 5 and axle 14, seals by O type circle 11, between supporting sleeve 15 and axle 14, seals by adjusting packing ring 16.
Handle 1 is fixing by handle set 19, and handle set 19 is fixed on valve body by spring bolt 20, and handle set 19 is sold 18 directly to households by cylinder and is fixed on axle 14.Valve gap 2 is fixed on valve body 3 by hexagon nut 21.On valve gap 2 and valve back seat cover plate 8, be reserved with respectively the hole of stationary axle 14.Between axle 14 and valve gap 2, be provided with and adjust packing ring 16, between axle 14 and valve back seat cover plate 8, be provided with and adjust packing ring 16.Between cam 13 and axle 14, be connected by socket head screw 9.Wherein, O type circle 11 and dovetail seal ring 12 are nitrile butadiene rubber material.
In handle set 19, be provided with the spring bolt for positioning cam 13 positions, on spring bolt, be provided with the spring bolt spring being used in conjunction with.
Working procedure: in the time of real work, be with moving axis 14 to rotate by manual tune handle 1, and then band moving cam 13, cam 13 drive valve plate assemblies 6 move left and right, and complete keying and the sealing of triple valve inlet 17; Adopt said method, can only use once-through operation, control two triple valve inlets 17, and can realize the sealing of two three-way valve.Even there is gap between the spheroid of duplex three-way valve and valve seat, in the time that valve cuts out, the pressure of high pressure side medium still can be pushed sealing plate body to outlet side valve seat, makes close contact between valve body and outlet side valve seat, therefore valve still has good sealability.
