Abstract

A wet electromagnetic change-over valve comprises a valve body, four cavities of a P, a B, a T and an A inside the valve body, an electromagnet connected on the valve body, and a valve core and a restoring spring which are arranged inside the electromagnet, wherein, the electromagnet and the valve body are connected through screw thread, and the lower end of an assembling deep hole of the valve body is below the central line; and the mouth of the P on the front of the valve body is cast with a P typeface, and the corresponding mouths of the B, the T and the A on the back side are separately cast with typefaces of a B, a T and an A. The electromagnet of the utility model is directly connected with the screw thread on the two ends of the valve body, thus advancing the sealing capability between the electromagnet and the valve body, and effectively solving the problem that the two ends of the electromagnetic valve leak oil; the assembling deep hole of the valve body is moved downwards to under the central line of the valve body, thereby reducing the deformation of the valve body in the process of assembling the electromagnetic valve, avoiding the phenomenon that a sliding valve is locked, and insuring reliably changing the direction; and moreover, the mouths of the P, the B, the T and the A of the valve body are cast with the typefaces of the P, the B, the T and the A, thereby greatly being convenient for the utilizing of the user.

Description

A kind of wet type solenoid directional control valve
Technical field
The utility model relates to a kind of industrial hydraulic control component, relates in particular to a kind of solenoid directional control valve.
Background technique
Under equal power situation, because little, in light weight, the compact structure of hydraulic actuator volume, stable working, reflection are soon, be easy to realize quick startup, braking and frequent advantages such as commutation, so it is widely used in each side such as machine-building, engineering construction, petrochemical industry, communications and transportation, military machine, mine metallurgy, light industry, agricultural machinery, fishery, forestry.Simultaneously, also be applied to each field of engineering technology such as space flight and aviation, ocean development, nuclear energy engineering and earthquake prediction.
Hydraulic transmission can not guarantee strict velocity ratio, mainly is to be caused by leakage except the compressibility of hydraulic oil, because hydraulic actuator is generally motive sealing, and precision prescribed height, long service life.Because hydraulic oil leaks easily, so efficient is lower, if deal with improperly, the hydraulic oil of leakage is contaminated site not only, but but also the generation of fire hazard and explosive accident.Because the electromagnet of solenoid directional control valve is to be installed on the valve body end face by fastening piece at present, thereby in order to reduce leakage, the valve body of hydraulic element and electromagnet connection part are had relatively high expectations on accuracy of manufacturing, have therefore improved the difficulty of processing of product greatly, have increased cost of production.Hydraulicdirectional control valve is a control unit in the Hydraulic Power Transmission System.Because the moving axially of its spool, so spool and valve body are generally movable sealing structure.So just can cause hydraulic oil to leak out more from the junction plane between electromagnet and the valve body.Solenoid valve valve body easy deformation in installation process easily produces the stuck phenomenon of guiding valve in addition.The negotiability of valve body and pressure are also low in the prior art simultaneously can't satisfy the modern industry needs.
The model utility content
Technical problem to be solved in the utility model is, a kind of wet type solenoid directional control valve is provided.
In order to address the above problem, the technical solution of the utility model is such:
A kind of wet type solenoid directional control valve, comprise valve body, the P of valve inner, B, four cavitys of T, A, be connected the electromagnet on the valve body, be arranged on the spool and the Returnning spring of electromagnet inside, wherein, adopt between described electromagnet and the valve body to be threaded, described valve body is installed the counterbore lower end below center line.
The p mouth place, front of described valve body is cast with " P " printed words, and the B of back correspondence, T, A mouth place are cast with " B ", " T ", " A " printed words.
Electromagnet of the present utility model directly is connected with valve body two ends screw thread, has improved the sealability between electromagnet and the valve body, has effectively solved solenoid valve two ends leakage of oil problem; Valve body is installed counterbore be displaced downwardly to below the valve body center line, reduced the valve body distortion in the solenoid valve installation process, prevent that the guiding valve stuck phenomenon from occurring, guarantee that commutation is reliable; P, B, T, A mouth place at valve body are cast with " P ", " B ", " T ", " A " printed words, greatly facilitate user's use.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments
Fig. 1 is a kind of wet type solenoid directional control valve of the utility model section of structure;
Fig. 2 is the T chamber and the counterbore position view of a kind of wet type solenoid directional control valve of the utility model;
Fig. 3 is the P cavity configuration schematic representation of a kind of wet type solenoid directional control valve of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, a kind of wet type solenoid directional control valve mainly comprises valve body 1, electromagnet 2, and control spool 3, Returnning spring 4, valve body 1 inside has P, B, four cavitys of T, A, and electromagnet 2 adopts with valve body 1 and is threaded, and directly is connected the two ends of valve body 1.
Referring to Fig. 2, Fig. 3, described valve body is installed counterbore 11 and is displaced downwardly to below the center line, so that reduce the valve body distortion, prevents that spool is stuck, in order to guarantee T groove intensity and through-current capacity the T groove is also done corresponding improvement, increases width of flow path, and negotiability is increased.
Referring to Fig. 1, be cast with " P ", " B ", " T ", " A " printed words at P, B, T, the A mouth place of electromagnetic valve body 1, greatly facilitate user's use.
Although the foregoing description is described the utility model, for the technician of the industry, still can do multiple variation to present embodiment, therefore, every employing similar variation of the present utility model all should be listed protection domain of the present utility model in.

Claims (2)

1. wet type solenoid directional control valve, comprise valve body, the P of valve inner, B, four cavitys of T, A, be connected the electromagnet on the valve body, be arranged on the spool and the Returnning spring of electromagnet inside, it is characterized in that adopt between described electromagnet and the valve body to be threaded, described valve body is installed the counterbore lower end below center line.
2. a kind of wet type solenoid directional control valve according to claim 1 is characterized in that, the p mouth place, front of described valve body is cast with " P " printed words, and the B of back correspondence, T, A mouth place are cast with " B ", " T ", " A " printed words.
