For solving the problem, the utility model provides a kind of adjustable valve body, comprise the valve body being provided with hollow lumen, described valve body comprises closed first end, and is provided with the second end with the first through hole of its inner space, it is characterized in that, be provided with in described valve body and driven by power plant, the spool that can within it slide axially, described spool and described valve body are transition fit, and described spool is also provided with:
-hollow passageway, it is blind hole, and extends to the other end from one end near described the second end of described spool along axis;
-circular groove, be arranged on the sidewall of described spool, and with the axes normal of described spool, when the end of described hollow passageway moves to minimum with the distance of the second end, described circular groove is communicated with the second through hole be arranged on described valve body sidewall, and described second through hole is inflated by the second air inlet system.
As further improvement of the utility model, described hollow passageway is cylindrical, and arranges with described first through hole concentric, and the aperture of described first through hole is greater than the internal diameter of described hollow passageway.
As further improvement of the utility model, described first end is provided with admission line, described power plant comprise the first air inlet system, described admission line is communicated with this first air inlet system by two position three way directional control valve, and another interface of described two position three way directional control valve is also connected with an exhaust duct.
The beneficial effects of the utility model are, in the utility model, arrange circular groove, dock with the second through hole, there is circumferential movement when preventing spool from sliding in valve body, cause the second through hole to dock inaccurate situation with hollow passageway and occur, be convenient to the second air inlet system and hollow pipe is inflated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of spool in Fig. 1;
Wherein: 2-valve body; 4-spool; 5-connecting passage; 6-hollow passageway; 8-circular groove; 10-second through hole; 12-admission line.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1, comprise the valve body 2 being provided with hollow lumen, described valve body 2 comprises closed first end, and be provided with the second end with the first through hole of its inner space, it is characterized in that, be provided with in described valve body 2 and driven by power plant, the spool 4 that can within it slide axially, described spool 4 is transition fit with described valve body 2, and described spool 4 is also provided with:
-hollow passageway 6, it is blind hole, and extends along axis to the other end from described spool 4 near one end of described the second end;
-circular groove 8, be arranged on the sidewall of described spool 4, and with the axes normal of described spool 4, described circular groove 8 is communicated with described hollow passageway 6 by connecting passage 5, when the end of described hollow passageway 6 moves to minimum with the distance of the second end, described circular groove 8 is communicated with the second through hole 10 be arranged on described valve body 2 sidewall, and described second through hole 10 is inflated by the second air inlet system.
Circular groove 8 is set, docks with the second through hole 10, when preventing spool 4 from sliding in valve body 2, occur circumferential movement, cause the second through hole 10 to dock inaccurate situation with hollow passageway 6 and occur, be convenient to the second air inlet system and hollow passageway 6 is inflated.
As further improvement of the utility model, described hollow passageway 6 is cylindrical, and arranges with described first through hole concentric, and the aperture of described first through hole is greater than the internal diameter of described hollow passageway 6.
Adopt this structure, when hollow passageway 6 is vented, all gas is all discharged by the first through hole, prevents from producing impact force to the second end.
As further improvement of the utility model, described first end is provided with admission line 12, described power plant comprise the first air inlet system, described admission line 12 is communicated with this first air inlet system by two position three way directional control valve, and another interface of described two position three way directional control valve is also connected with an exhaust duct.
Arrange two position three way directional control valve, can control air inlet and exhaust, when spool 4 lifting is got on by needs, the first air inlet system is communicated with admission line 12 by two position three way directional control valve, and gas enters in valve body 2 inner chamber, by valve body jack-up by admission line 12.When needs spool 4 resets, two position three way directional control valve, by admission line 12 and exhaust duct pipeline communication, draws off gas.
Concrete principle of the present utility model is as follows:
(1) admission line 12 is connected with the first air inlet system by two position three way directional control valve, and the first air inlet system is inflated in the inner chamber of valve body 2 by admission line 12, by spool 4 jack-up;
(2) circular groove 8 docks with the second through hole 10, and the second air inlet system is ventilated to the second through hole 10, and this gas is inflated in hollow passageway 6 by the connecting passage 5 be communicated with the second through hole 10, thus outwards does work;
(3) first air inlet systems and the second air inlet system quit work, and spool 4 is in the effect of gravity, and slide downward, regulate two position three way directional control valve that suction tude is communicated with outlet pipe, gas is discharged by exhaust duct.
Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
