Abstract
The utility model relates to a five-way three-position electromagnetic valve and aims to provide the five-way three-position electromagnetic valve provided with an integral type spacer bush. The five-way three-position electromagnetic valve comprises a valve body and a valve drive part arranged on the valve body, wherein the valve body is internally provided with a central spindle, and the spacer bush is arranged between the central spindle and the valve body; the outer wall of the space bush is provided with a four annular bosses to define out three first grooves, and the groove bottoms of two adjacent first grooves are provided with a plurality of through holes; and the outer wall of each boss is respectively provided with an annular second groove, and the second groove is internally provided with a sealing ring. The five-way three-position electromagnetic valve has the advantages that the abrasion of the sealing ring is improved, the start air pressure and the reversing time are reduced and shortened, and the five-way three-position electromagnetic valve is suitable for promotion and use.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of five mouthfuls of three-position electromagnetic valves.
Background technique
Five mouthfuls of three-position electromagnetic valves that occur in the market as shown in Figure 1, comprise valve body a, valve drive portion b, be provided with axle core c in the described valve body a, be provided with spacer between axle core c and the valve body a, this spacer is comprised of copper spacer d and engineering plastics spacer e, for split type, in axle core c movement process, can through the joint of copper spacer d and engineering plastics spacer e, cause the damage of the seal ring f on the axle core c.In addition, spacer is provided with a plurality of pores, axle core c through out-of-date also can be to seal ring f injury.
The model utility content
The purpose of this utility model is to provide a kind of five mouthfuls of three-position electromagnetic valves that are provided with the integral type spacer, damages the problem of seal ring with the joint that solves the split type spacer that exists in the background technique.
To achieve these goals, the technological scheme of five mouthfuls of three-position electromagnetic valves of the utility model is: a kind of five mouthfuls of three-position electromagnetic valves, comprise valve body and valve drive portion provided thereon, be provided with the axle core in the described valve body, be provided with spacer between axle core and the valve body, have four road annular boss on the spacer outer wall and define three the first grooves, wherein the bottom land of two adjacent the first grooves is equipped with a plurality of through holes, be equipped with the second groove of ring-type on the outer wall of per pass boss, be provided with seal ring in the second groove.The mentality of designing of this technological scheme is: the spacer of five mouthfuls of three-position electromagnetic valves on the former market is split-type structural, and the technical program is designed to integral structure, thereby has eliminated the problem of the joint damage seal ring of split type spacer.
As preferably, the external diameter of described four road boss increases successively, and described through hole is positioned at adjacent two the first grooves that boss with less three external diameters defines.The external diameter of four road boss increases successively, is that the end that the boss external diameter of spacer is little is packed into conveniently in the inner chamber of valve body in order to install, and the position of through hole then needs corresponding with pore on the valve body.
As preferably, described through hole is circumferentially uniform spacer.Through hole is evenly distributed at the circumferential uniform air-flow that makes of spacer.
As preferably, the inwall of described spacer is provided with twice the 3rd groove, and described through hole is arranged at respectively the bottom land of twice the 3rd groove.Through hole, is avoided seal ring is damaged so the position of corresponding through hole arranges the 3rd groove on inwall at the seal ring that still can damage on the spacer inwall on the axle core.
As preferably, described seal ring is two-way sealing ring.Two-way sealing ring has under the pressure state bilateral or monolateral, and lip all can open, and the larger lip of pressure degree of opening is larger, sealability is better, and its filling volume is less, even frictional force is also very little in the bilateral situation that pressure arranged, has therefore reduced startup air pressure and turn around time.
The beneficial effect of five mouthfuls of three-position electromagnetic valves of the utility model is: improved the wearing and tearing of seal ring, and reduced startup air pressure and turn around time.
Description of drawings
Fig. 1 is a kind of structural representation of five mouthfuls of three-position electromagnetic valves in the prior art;
Fig. 2 is a kind of structural representation of five mouthfuls of three-position electromagnetic valves of the utility model;
Fig. 3 is the structural representation of spacer;
Fig. 4 is the structural representation of two-way sealing ring.
Number in the figure is respectively: 1 valve body, 2. valve drive portions, 3. axle cores, 4. spacers, 5. first grooves, 6. second grooves, 7. two-way sealing rings 8. the 3rd groove.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is further described specifically below by embodiment.
Embodiment:
A kind of five mouthfuls of three-position electromagnetic valves, as shown in Figure 2, comprise valve body 1 and valve drive portion 2 provided thereon, be provided with axle core 3 in the described valve body 1, be provided with spacer 4 between axle core 3 and the valve body 1, have four road annular boss on the spacer outer wall and define three the first grooves 5, be equipped with on the outer wall of per pass boss in the second groove 6, the second grooves 6 of ring-type and be provided with two-way sealing ring 7.
The external diameter of described four road boss increases successively, and the bottom land of adjacent two the first grooves 5 that the boss of less three external diameters defines has a plurality of circumferential uniform through holes at spacer 4.The inwall of described spacer 4 is provided with twice the 3rd groove 8, and described through hole is arranged at respectively the bottom land of twice the 3rd groove 8.
This integral type spacer structure has improved the wearing and tearing of seal ring, and has reduced startup air pressure and turn around time.
Above-mentioned described specific embodiment only is that the preferable examples explanation is done in design of the present utility model.All any modifications of making within spirit of the present utility model and principle or replenish or be equal to alternatively all should be included within the protection domain of the utility model claim.
