Abstract
A two-position and two-way electromagnetic valve comprises a valve body and a valve element. The valve element can be arranged in an inner cavity of the valve body in a vertical sliding manner. An air inlet and an air outlet are formed in the side edge of the valve body. The air inlet and the air outlet are arranged in parallel in the height direction. A ventilation groove is formed in the side face of the valve element in the circumferential direction. The upper end of the valve element is connected with the lower end of an elastic element. The upper end of the elastic element is connected with a coil used for driving the valve element to slide upwards after electrification, and the coil is fixed to the upper portion of the inner cavity of the valve body. In the electrification state of the coil, the height of the ventilation groove is consistent with the height of the air inlet and the height of the air outlet, the ventilation groove communicates with the air inlet and the air outlet, and in the non-electrification state of the coil, the height of the ventilation groove is smaller than that of the air inlet and that of the air outlet. The two-position and two-way electromagnetic valve high in adjusting precision is provided.
Description
Technical field
The present invention relates to valve technology field, especially a kind of two-position two-way solenoid valve.
Background technology
It is known that electromagnetic valve is used to control the automation foundation element of flow direction, belong to executor, there are two formula actions of switch.Existing Pneumatic high-speed switch valve is studied, and concentrates on bi-bit bi-pass formula, is concentrated mainly on the research of cut-off type pneumatic on-off valve, and the research for side valve type pneumatic operated valve is less.There is the defect that degree of regulation is not high in existing two-position two-way solenoid valve.Accordingly, it would be desirable to improve.
Summary of the invention
For the deficiency that the degree of regulation overcoming existing two-position two-way solenoid valve structure is not high, the present invention provides the two-position two-way solenoid valve that a kind of degree of regulation is higher.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of two-position two-way solenoid valve, including valve body and spool, described spool can slide up and down to be arranged on body cavity, the side of described valve body is provided with air inlet and gas outlet, described air inlet and gas outlet height and position be arranged in parallel, and the side circumference of described spool has vent grooves, and the upper end of described spool connects with the lower end of flexible member, the upper end of described flexible member be used for powering on after coil with movable valve plug upward sliding connect, described coil is fixed on the top of body cavity；Under described coil power-up state, vent grooves is highly consistent with described air inlet and gas outlet and communicate, and under the non-power-up state of described coil, the height of vent grooves is less than the height of described air inlet and gas outlet.
Further, between described spool and valve body it is matched in clearance.
Valve gap is installed at the top of described body cavity, and described coil is fixed on valve gap.
Described air inlet is identical with the width of gas outlet, and described in the width ratio of described vent grooves, the width of gas outlet is little.
The two-position two-way solenoid valve simple in construction of the present invention, spool is loaded valve body, then spring is loaded, it is loaded on coil and valve gap, being coordinated by the dimensional tolerance between spool external diameter and valve body inner bore diameter and make there is therebetween sufficiently small gap, the lower effect that can play valve seal also can guarantee that spool can slide up and down at valve inner in this gap.
When spool is in primary importance in described valve body, described spool blocks the gas circuit of air inlet and gas outlet, and gas circuit is closed；When described spool is in the second position in described valve body, the vent grooves of spool communicates with the gas circuit of air inlet and gas outlet, and gas circuit is opened.Switch motion is simple and quick.
Beneficial effects of the present invention is mainly manifested in: switch motion is simple and quick, degree of regulation is higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1～Fig. 4, a kind of two-position two-way solenoid valve, including valve body 1 and spool 2, described spool 2 can slide up and down to be arranged on valve body 1 inner chamber, the side of described valve body 1 is provided with air inlet 3 and gas outlet 5, described air inlet 3 and gas outlet 5 height and position be arranged in parallel, the side circumference of described spool 2 has vent grooves 4, the upper end of described spool 2 connects with the lower end of flexible member 6, the upper end of described flexible member 6 be used for powering on after coil 7 with movable valve plug upward sliding connect, described coil 7 is fixed on the top of body cavity；Under described coil 7 power-up state, vent grooves 4 is highly consistent with described air inlet 3 and gas outlet 5 and communicate, and under the described non-power-up state of coil 7, the height of vent grooves 3 is less than the height of described air inlet 3 and gas outlet 5.
Valve gap 8 is installed at the top of described body cavity, and described coil 7 is fixed on valve gap 8.Described air inlet 3 is identical with the width of gas outlet 5, and described in the width ratio of described vent grooves 4, the width of gas outlet 5 is little.It is of course also possible to arrange for other.
In the present embodiment, the side of valve body 1 is provided with the parallel air inlet in position 3 and gas outlet 5；The side circumference of spool 2 offers vent grooves 4, and the height of described vent grooves 4 is less than the bore of air inlet 3 (gas outlet 5)；When spool 2 is in primary importance in valve body 1, spool 2 blocks air inlet 3 and the gas circuit of gas outlet 5, and gas circuit is closed；When spool 2 is in the second position in valve body 1, the vent grooves 4 of spool 2 communicates with the gas circuit of air inlet 3 and gas outlet 5, and gas circuit is opened.
The flexible member 6 arranged between spool 2 and coil 7 is spring, and spring has downward thrust and spool is contacted downwards in body cavity bottom；Being matched in clearance between spool 2 and valve body 1, the material of spool 2 is hard material.
Above-described embodiment is presently preferred embodiments of the present invention; it it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, be regarded as falling within the scope of the rights protection of patent of the present invention.
