The utility model discloses a magnetic exchange valve sets up pressure compensation pole and case respectively through the both ends at the electro -magnet, because the pressure compensation pole communicates with each other with external environment respectively with the case, can transmit external environment pressure to the both ends of electro -magnet respectively, and the mode of offsetting through both ends pressure realizes having solved the pressure compensation problem to " the hard compensation " of deep water pressure.
Description
Technical field
The utility model relates to the solenoid directional control valve in control unit field in Fluid Transmission and Control system, particularly under water with the solenoid directional control valve that uses in deep-sea.
Background technique
As solenoid directional control valve will be used under water, consider the working medium of its primary component electromagnet and overcome the problem of deep-water pressure, adopt wet electro-magnet to solve in prior art in deep water, run into water depth pressure compensation problem, being arranged on one by wet electro-magnet is full of in the closed containing cavity of mineral oil (working medium), realize water depth pressure auto-compensation by closed containing cavity upper piston or air bag, but the price of wet electro-magnet is higher, complex structure, and wherein used mineral oil viscosity is large, dynamic Railway transportation in electromagnet can be subject to larger damping and viscous friction when moving, cause the speed of response of electromagnet slow.Specifically " soft compensation " scheme asks for an interview Fig. 1, increases novel substance mineral oil S
3o, by piston, make its pressure equal with external pressure, act on dynamic iron S
1mon, produce static pressure F
ho, compensate F
hw; Meanwhile, because mineral oil viscosity is large, when dynamic Railway transportation moves, damping and viscous friction greatly, affect performance; Owing to introducing S
3o, act on seal ring S
2son pressure F
meincrease, frictional force increases.
Although general air-gap solenoid price is lower, because it can only use under air gap environment, and be difficult to avoid seepage problem when using under water, therefore air-gap solenoid is difficult in deep water.
Model utility content
Technical problem to be solved in the utility model, is just to provide one and can uses with land under water, particularly under water with the solenoid directional control valve that uses in deep-sea.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of solenoid directional control valve, comprise the valve body of attached cavity, in the cavity of valve body, electromagnet is set, the cavity two ends of valve body are respectively with upper cover plate and valve base sealing, described valve seat is arranged import and outlet, the cavity in valve seat communicates with import and outlet, arranges pressure compensation bar between described upper cover plate and electromagnet, one end of pressure compensation bar is stretched out outside the through hole of upper cover plate, and the other end is limited in the space between upper cover plate and electromagnet; In the valve body that spool is arranged on electromagnet bottom and valve seat cavity.
Further, the center line of described spool and pressure compensation bar is located along the same line.
Further, described spool is almost identical with the diameter of pressure compensation bar.
Further, the bottom of described spool is that truncated cone shape is most advanced and sophisticated.
Further, described pressure compensation bar cross section is inverted T-shaped.
Further, described upper cover plate connects water-joint by transit joint.
Further, Glais ring cover plate and Glais ring are set in spool periphery.
Further, Glais ring cover plate and Glais ring are set in pressure compensation bar periphery, and by screw, Glais ring cover plate are fixedly connected with upper cover plate.
The beneficial effects of the utility model are:
Solenoid directional control valve disclosed in the utility model, by the two ends at electromagnet, pressure compensation bar and spool are set respectively, because pressure compensation bar and spool communicate with external environment respectively, ambient pressure environment can be passed to respectively the two ends of electromagnet, the mode offset by pressure at two ends realizes, to deep-water pressure " firmly compensating ", solving pressure compensation problem.Solenoid directional control valve disclosed in this invention, electromagnet, air gap environmental work, does not have fluid, there will not be when electromagnet being moved because fluid viscosity is large and is subject to larger damping and viscous friction.
Solenoid directional control valve disclosed in the utility model, is placed in electromagnet in the cavity of valve body, then by the upper cover plate that cooperatively interacts and pressure compensation bar, valve seat and spool, electromagnet and external environment is completely cut off, good sealing effect.
Solenoid directional control valve disclosed in the utility model, pressure compensation bar and spool are installed respectively, not only easy for installation, adjustable positioning tolerance between the two in installation process, and can reduce the wearing and tearing to seal ring in installation process, avoid occurring seepage.
Solenoid directional control valve disclosed in the utility model, the sectional shape of pressure compensation bar is inverted T-shaped, has both facilitated it to move with electromagnet, and has been limited in again the space between upper cover plate and electromagnet, makes it can not deviate from outside upper cover plate, ensures sealing effect further.
Accompanying drawing explanation
Fig. 1 is wet electro-magnet " soft compensation " schematic diagram disclosed in the utility model background technique.
Fig. 2 is the structural representation of the solenoid directional control valve disclosed in the utility model embodiment 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.Below for sake of convenience, the said orientation such as upper and lower of each embodiment refers to each parts position in the accompanying drawings, does not play restriction effect to the protection domain of patent right.
Embodiment 1, as shown in Figure 1, present embodiment discloses a kind of solenoid directional control valve, comprise the valve body 13 of attached cavity, electromagnet 14 is set in the cavity of valve body 13, the cavity two ends of valve body seal with upper cover plate 10 and valve seat 18 respectively, described valve seat is arranged import P and the outlet O of turnover of supplying water, cavity in valve seat and import P and export O and communicate, water enters after cavity through import P and flows out through outlet O, commutation can be realized, its improvements are: between described upper cover plate 10 and electromagnet, arrange pressure compensation bar 11, one end of pressure compensation bar 11 is stretched out outside the through hole of upper cover plate 10, the other end is limited in the space A between upper cover plate 10 and electromagnet 14, arrange spool 15 in valve body in electromagnet bottom and valve seat cavity, at electromagnet power failure state, under fluid pressure effect, spool 15 moves to upper cover plate direction, the import P on valve seat 18 and the cavity UNICOM between outlet O, and solenoid valve is opened, when electromagnet obtains electric, pressure compensation bar is downward under external force, and electromagnet is moved to lower cover plate direction by electromagnetic attraction effect, thus promotion spool 15 also moves downward, and blocks the UNICOM between import P and outlet O in valve seat, closed electromagnetic valve.
Alternatively, this spool 15 is located along the same line with the center line of pressure compensation bar 11, and the two diameter is almost identical.
