Accompanying drawing 1 is for the master of the utility model most preferred embodiment looks sectional view,
Current schematic representation when accompanying drawing 2 is opened for the utility model most preferred embodiment,
Coding in the accompanying drawing is respectively: 1 is valve body, and 2 is stifled for plug, and 3 is rubber cushion, and 4 is control valve, 5 is elastic seal cartridge, and 6 is spool, and 7 is seal ring, and 8 is bolt, 9 is spring washer, and 10 is nut, and 11 is valve gap, and 12 is valve outlet, 13 is the spool hand-hole, and 14 is sealing strip, and 15 spools portal, and 16 is the control room, 17 is tap hole, and 18 are the valve body inlet, and 19 are the spool inlet, and 20 are the spool outlet, 21 is partition wall, and 22 is interior sealing gasket, and 23 is the external sealed pad.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
Shown in attached Fig. 1 and 2, this shunting fluid-controlled valve comprises valve body 1 and spool 6, and valve body inlet 18 and valve outlet 12 arranged on the valve body 1, spool inlet 19 is arranged on the spool 6, spool outlet 20 and partition wall 21, and partition wall 21 is between spool inlet 19 and spool outlet 20, on spool 6, there is the spool that is no less than to portal 15 with spool inlet 19 and the mutual UNICOM of spool 6 outer surfaces, on spool 6, have and be no less than one spool hand-hole 13 spool 6 outer surfaces and spool outlet 20 mutual UNICOMs, spool 6 outer surfaces tighten and are with elastic seal cartridge 5, spool 6 is fixedly mounted in the valve body 1, spool inlet 19 communicates with valve body inlet 18, spool outlet 20 communicates with valve outlet 12, valve body 1 inboard have and spool 6 outer surfaces on elastic seal cartridge 5 between the control room 16 that constitutes, have on the valve body 1 and valve body inlet 18 tap holes that communicate 17, and tap hole 17 communicates with control room 16 and control valve 4, and controller is installed on control valve 4;
During use: the valve body inlet 18 that at first will shunt fluid-controlled valve is connected on the liquid inlet pipe (as intake pipe), when control valve 4 is opened, the liquid that is valve body inlet 18 can flow out from tap hole 17, because suction function makes the hydraulic pressure of control room 16 hydraulic pressure less than valve body inlet 18, the most of current that enter spool inlet 19 portalled 15 o'clock by spool, make elastic seal cartridge 5 distortion spreadings under pressure, current are that sealing strip 14 enters spool outlet 20 by spool hand-hole 13 by the distortion spreading gap of elastic seal cartridge 5, flow out by valve outlet 12 then, thereby realize the unlatching of this shunting fluid-controlled valve; When control valve 4 is closed, the liquid that is valve body inlet 18 can not be when tap hole 17 flows out, the hydraulic pressure in control room 16 and valve body 18 pressure that enter the mouth equate, preload pressure when elastic seal cartridge 5 is installed in addition, make pressure that elastic seal cartridge 5 acts on spool 6 outer surfaces greater than the portal hydraulic pressure at 15 places of spool, this moment, elastic seal cartridge 5 was pressed on partition wall 21 outer surfaces, and portal 15 water of spool can not be flowed, the closing of existing this shunting fluid-controlled valve of historical facts or anecdotes.Wherein, controller is installed preferably on control valve 4, like this unlatching of control valve 4 or just close and to have realized by controller.
In order further to increase sealing effect, shown in attached Fig. 1 and 2, on the spool 6 of partition wall 21 outer surfaces, seal ring 7 is installed, when controller is closed control valve 4, make elastic seal cartridge 5 by the good sealing effect of maintenance between the partition wall wall 21 of seal ring 7 and spool 1, thereby this shunting fluid-controlled valve does not leak when cutting out.
Shown in attached Fig. 1 and 2, it is 15 preferably close or equate with the valve body 18 places connection water pipe internal diameter that enters the mouth with the discharge area of spool hand-hole 13 that the spool of this shunting fluid-controlled valve portals.
For the ease of spool 6 is installed, shown in attached Fig. 1 and 2, preferably spool 1 is fixedly mounted in the valve body 1, but also can adopts other mounting type by valve gap 11; Shown in attached Fig. 1 and 2, control valve 4 is not interconnected with valve outlet 12, but control valve 4 and valve outlet 12 can be interconnected as required, and the liquid that tap hole 17 can be distributed is when control valve 4 is opened like this, flow back to valve outlet 12, thereby realize recovery the liquid that distributes.
Shown in attached Fig. 1 and 2, interior sealing gasket 22 is preferably arranged between spool 6 and the valve body 1, and the elastic seal cartridge 5 of cover links into an integrated entity preferably also on interior sealing gasket 22 and the spool 6, can improve sealing effect like this; In like manner, between valve body 1 and the valve gap 11 external sealed pad 23 is arranged preferably, and the elastic seal cartridge 5 of cover links into an integrated entity preferably also on external sealed pad 23 and the spool 6; Elastic seal cartridge 5 can be rubber sleeve or elastomeric plastics cover; Seal ring 7 is rubber seal or plastic seal ring.
Wherein, controller recited above can be solenoid valve or liquid level valve or manually operated valve, and these control needs when using are decided.
One's duty flow liquid force control valve is through preservative treatment, and the pipeline control or the tank fill level that can also be used for the less fluids of viscosity such as chemical industry, oil are controlled automatically.
In sum, the utility model is simple in structure, is convenient to make processing, and cost is low, and is easy to maintenance, and the better seal performance is arranged.
