Background technique
During clear water turnover plasma discharge conveying equipment, because valve working is at high-pressure high-flow environment, the common stop valve valve of current use, during work, the High Pressure Difference of intake-outlet had both caused larger hydraulic shock, turn increase lifting force when spool lifts, bring pressure to the valve in work, have impact on the working life of valve.
Model utility content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide that a kind of noise is low, the simple stop valve structure of structure.
Described a kind of stop valve structure, comprise the stop valve body containing water intake and water outlet, pilot valve, in described stop valve body, stop valve clack is set, seat of stop valve, described pilot valve comprises interconnective pilot valve and guide's valve seat, it is characterized in that described stop valve body also arranges hydraulic drive mechanism, described hydraulic drive mechanism comprises hydraulic cylinder body and the piston rod set within it and piston, described piston rod is connected with stop valve clack by flange, pilot valve and guide's valve seat are arranged between piston rod and stop valve clack.
Described a kind of stop valve structure, it is characterized in that being set to cone-shaped structure bottom described pilot valve, guide's valve seat is arranged the cone shape hole mated with it, insert bottom pilot valve in cone shape hole and form sealing pair with guide's valve seat, bottom screw thread and piston rod.
Described a kind of stop valve structure, it is characterized in that described stop valve body inner cavity top arranges isolation ward, described isolation ward is connected with repairing room.
Above-mentioned a kind of stop valve structure, comprise stop valve body, the pilot valve containing water intake and water outlet, stop valve clack, seat of stop valve are set in stop valve body, pilot valve comprises interconnective pilot valve and guide's valve seat, stop valve body also arranges hydraulic drive mechanism, hydraulic drive mechanism comprises hydraulic cylinder body and the piston rod set within it and piston, piston rod is connected with stop valve clack by flange, and pilot valve and guide's valve seat are arranged between piston rod and stop valve clack.The utility model is by adopting above-mentioned technology, by controlling the unlatching of stop valve clack, reach and control inflow that the high pressure water that enters of water intake arranges to the slurry pipeline steel be connected with water outlet and cut-off, because the unlatching of stop valve clack is controlled by pilot valve by hydraulic drive mechanism, open and close in its working procedure frictional force little, bear that pressure is large, sealability remains intact, and without the need to increasing the size of valve, using scope is wide, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A place structure for amplifying schematic diagram in the utility model Fig. 1.
In figure: 1-water intake, 2-piston rod, 3-hydraulic cylinder body, 4-piston, 5-repairing room, 6-isolation ward, 7-flange, 8-pilot valve, 9-stop valve clack, 10-seat of stop valve, 11-water outlet, 12-guide's valve seat, 13-stop valve body.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As depicted in figs. 1 and 2, a kind of stop valve structure, for controlling the clear water inlet and outlet slurry pipeline steel equipment that high-pressure clear water pump is got, it comprises the stop valve body 13 containing water intake 1 and water outlet 11, pilot valve and hydraulic drive mechanism, described water intake 1 is connected with high-pressure water pump, water outlet 11 is connected with slurry pipeline steel equipment, controlled the unlatching of the stop valve clack 9 in stop valve body 13 by pilot valve by hydraulic drive mechanism, close and opening degree, in described stop valve body 13, stop valve clack 9 is set, seat of stop valve 10, described pilot valve comprises interconnective pilot valve 8 and guide's valve seat 12, described hydraulic drive mechanism comprises hydraulic cylinder body 13 and the piston rod 2 set within it and piston 4, described piston rod 2 is connected with stop valve clack 9 by flange 7, pilot valve 8 and guide's valve seat 12 are arranged between piston rod 2 and stop valve clack 9, be specially, cone-shaped structure is set to bottom pilot valve 8, guide's valve seat 12 is arranged the cone shape hole mated with it, insert bottom pilot valve 8 in cone shape hole and form sealing pair with guide's valve seat 12, bottom screw thread and piston rod 2, the utility model is in order to increase sealing, stop valve body 13 inner chamber one end is avoided to seal the wear-out failure sealing of position and Sealing thereof because of piston rod 2, at stop valve body 13 inner cavity top, isolation ward 6 is set, isolation ward 6 is made up of rubber membrane, this isolation ward 6 is connected with repairing room 5, repairing room 5 is built with Lubricants, the change of isolation ward 6 volume Lubricants compensating piston bar 2 in repairing room 5 being moved up and down ten million is passed through when needing.
As shown in the figure, control procedure of the present utility model is as follows: when stop valve is opened, piston 4 drives on piston rod 2 and moves under the effect of hydraulic actuating fluid, first piston rod 2 drives in pilot valve 8 and moves, pilot valve is opened, water inlet and outlet cavity volume is all pressed, when pilot valve 8 reaches maximum lift, water inlet and outlet chamber pressure reaches balance, at this moment piston rod 2 shoulder contacts with flange 7, drive on stop valve clack 9 and move, achieve the unlatching of stop valve, due to the effect of pilot valve, stop valve clack 9 is when opening, the pressure of its upper and lower reaches balance, reduce lifting force and the hydraulic shock power of stop valve clack 9, thus noise when reducing the size of valve and reduce valve opening, make the service behaviour of whole slurry pipeline steel equipment and be improved working life, when stop valve is closed, piston 4 drives piston rod 2 to move down under the effect of hydraulic actuating fluid, stop valve clack 9 is first closed, and then closes pilot valve.
High pressure clear water stop valve of the present utility model, by controlling the unlatching of stop valve clack, reach and control inflow that the high pressure water that enters of water intake arranges to the slurry pipeline steel be connected with water outlet and cut-off, because the unlatching of stop valve clack is controlled by pilot valve by hydraulic drive mechanism, open and close in its working procedure frictional force little, bear that pressure is large, sealability remains intact, and without the need to increasing the size of valve, using scope is wide, is suitable for applying.
