Description
Technical field
The utility model relates to a kind of valve.Specifically, be to utilize hydraulically powered 3-position-3-way seawater selector valve, be applicable in the hydraulic system of submersible under water.
Background technique
At present, the seawater selector valve that uses in the hydraulic system of various submersibles mostly is a spool-type valves.When this spool-type valves is worked, rely on the cylindrical spool of several shoulders, do axial motion, corresponding liquid road is communicated with or disconnection with respect to the valve body that has several undercut grooves.This spool-type valves has reliable in action, good manufacturability, realizes advantages such as multiple function easily.But because it uses seawater as working medium, and seawater has characteristics such as etching reagent is strong, viscosity is low, poor lubricity, pressure for vaporization height make this spool-type valves have problems such as leakage rate is bigger.For dwindling the gap between spool and valve pocket, if adopt seal ring to seal, not only can increase spool resistance to motion, make driving force along with increase, and the impurity in the seawater easily enters between seal ring, spool and the valve pocket of relative movement, thereby causes faults such as wearing and tearing, seal failure and the spool of seal ring, spool and valve pocket be stuck.Therefore, this selector valve leakage rate is big, and poor reliability is difficult to guarantee normal operation.
The model utility content
Problem to be solved in the utility model is to overcome defective in the background technique, a kind of 3-position-3-way hydraulic control kingston valve is provided.This 3-position-3-way hydraulic control kingston valve, good reliability can be guaranteed normal operation.
For addressing the above problem, take following technological scheme:
3-position-3-way hydraulic control kingston valve of the present utility model comprises valve body, and two unit valve pockets that are parallel to each other are arranged in this valve body, and the same end of two unit valve pockets is connected, and the control oil-in is arranged respectively on their the other end.Wherein, on the end valve body that two unit valve pockets are communicated with water intake is arranged.In the two unit valve pockets valve rod is arranged all, on valve rod one end near the control oil-in piston is arranged all, the other end all has spool, and the diameter of this spool is greater than the diameter of valve rod.On the outer side wall relative position of two unit valve pockets water outlet is arranged all, this two water outlet is connected with that segment unit valve pocket of respective pistons and valve core chamber respectively.Water outlet is communicated with two unit valve pockets on that segment unit valve pocket inwall between the end all circumferential boss, and said spool is in circumferential boss and the valve pocket that is communicated with between the end, and Returnning spring is all arranged between the outer end of spool and valve pocket.The inner side surface that is characterized in said spool and circumferential boss is taper, and spool one end that links to each other with piston is less than the other end.
Rubber sealing film is all arranged on the valve rod.
Take above scheme, have the following advantages:
Because the circumferential boss inner side surface of its spool of 3-position-3-way hydraulic control kingston valve of the present utility model and unit valve pocket is taper, and spool one end that links to each other with piston is less than the other end.Impurity in the seawater is less in the possibility that valve port is detained, and the sealing valve port reliable performance is compared with spool-type valves, can reduce leakage rate greatly.、
Owing on the valve rod rubber sealing film is arranged, seawater and hydraulic oil are kept apart effectively again, make the Sealing of not doing relative movement on the spool, thereby overcome that the spool-type valves leakage rate is big, poor reliability, be difficult to guarantee the problem normally moved.
Description of drawings
Accompanying drawing is a 3-position-3-way hydraulic control kingston valve structural representation of the present utility model.
Embodiment
As shown in drawings, 3-position-3-way hydraulic control kingston valve of the present utility model contains valve body 1, be provided with two unit valve pockets that are parallel to each other in this valve body, the same end of two unit valve pockets is connected, be processed with control oil-in 13 and 14 on their the other end respectively, under the user mode, this two control oil-in is connected with hydraulic oil source.Wherein, be processed with water intake 2 on the middle outer side wall of the end valve body 1 that two unit valve pockets are communicated with, this water intake is connected with seawater under user mode.Be separately installed with valve rod 5 and 6 in the two unit valve pockets, near all being fixed with piston 9 or 10 on the valve rod 5 of controlling oil-in 13 or 14 or 6 one ends, the other end all is processed with spool 17 or 18, and the diameter of this spool is greater than the diameter of valve rod 5 or 6.All be processed with water outlet 3 or 4 on the outer side wall relative position of two unit valve pockets, this two water outlet respectively with respective pistons 9 or 10 and that segment unit valve pocket of spool 17 or 18 be connected.Two water outlets 3 and 4 are communicated with two unit valve pockets on that segment unit valve pocket inwall between the end and all are processed with circumferential boss 15 and 16, said two spools 17 and 18 respectively at two circumferential boss 15 and 16 with the valve pocket that is communicated with between the end in, and that section valve pocket of spool 17 or 18 outer ends all is equipped with Returnning spring 11 or 12.Wherein, spool 17 or 18 and circumferentially boss 15 or 16 inner side surface be taper, and the spool 17 that links to each other with piston 9 or 10 or 18 1 ends are all less than the other end.
Keep apart effectively for making between seawater and hydraulic oil, rubber sealing film 7 or 8 all are installed on valve rod 5 or 6.
During work, seawater enters valve pocket from water intake 2.Because the pressure of seawater acts on the end of spool 17 or 18, the action direction of this pressure is identical with the pretightening force of Returnning spring 11 or 12.In carrying out during bit function, under Returnning spring 11 or 12 pretightening forces and seawater pressure acting in conjunction, two spools 17 and 18 all tightly to snap in corresponding circumferential boss 15 or 16 be in the valve port, flow channels is by deadend, makes water intake 2 and two water outlets 3 or 4 not connected.When carrying out the side bit function, hydraulic oil enters in the unit valve pocket from a control oil-in 13 or 14, under action of hydraulic force, piston 9 or 10 in this unit valve pocket overcomes Returnning spring 11 or 12 pretightening forces and seawater pressure, making spool 17 or 18 break away from corresponding circumferential boss 15 or 16 is valve port, valve port is opened, water intake 2 is communicated with water outlet 3 or 4 on the corresponding units valve pocket sidewall.Behind the end-of-job, the hydraulic power fuel cut-off, hydraulic coupling disappears, piston 9 or 10 can Returnning spring 11 or 12 and the seawater pressure acting in conjunction under promote spool 17 or 18 to shift to circumferential boss 15 or 16 be valve port, directly cause valve port to be closed, bit function in the recovery.
