Detailed Description
The following description is of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, which is further described with reference to the accompanying drawings and examples.
Examples are shown in fig. 1 and 2: the two-position three-way switch electromagnetic valve comprises an electromagnet assembly and a main valve assembly, wherein the electromagnet assembly comprises an armature 10, a stop iron 15, a pole shoe 14, a yoke 16, a coil 17, an ejector rod 11 and a magnetism isolating gasket 13, the coil 17 is positioned in the yoke 16 and can generate a magnetic field after being electrified, and the pole shoe 14 can enable the magnetic field to obtain better linear distribution; the stop iron 15 is fixedly connected with the main valve assembly, and is matched with the armature 10 to enable the armature 10 to move under the action of magnetic force; the magnetism isolating gasket 13 is located between the armature 10 and the pole shoe 14 on the electromagnet assembly, and can effectively isolate electromagnetic force between the armature 10 and the pole shoe 14, so that electromagnetic force generated between the armature 10 and the stop iron 15 is not reduced. The ejector rod 11 is fixedly connected with the armature 10 and is linked with the armature, the front end of the ejector rod 11 is contacted with the valve ball 24, and the rear end of the ejector rod is in certain displacement interval with the inner end surface of the pole shoe 14; thus, after being electrified, the armature 10 drives the ejector rod 11 to move forward under the action of electromagnetic force, so that the valve ball 24 seals the oil inlet 20.
The main valve assembly comprises a valve body 23, a valve ball 24, an inlet ball valve seat 25 and an oil drain ball valve seat 26, wherein the valve body 23 is provided with an oil inlet 20, an oil outlet 21 and an oil drain port 22, a through hole on the inlet ball valve seat 25 is communicated with the oil inlet 20, and a through hole on the oil drain ball valve seat 26 is communicated with the oil drain port 22; the inlet ball valve seat 25 is opposite to the drain ball valve seat 26, a valve ball accommodating space is formed between the inlet ball valve seat and the drain ball valve seat, and the valve ball 24 is positioned in the valve ball accommodating space; the front end of the plunger 11 passes through the drain ball valve seat 26 and contacts the valve ball 24 in use. The valve ball 24 is in a normally open state under the action of hydraulic oil so as to supply oil to the whole system, namely the valve ball 24 is jacked up by hydraulic pressure at the oil inlet 20 and jacked into the oil drain ball valve seat 26 to seal the oil drain port 22, so that the oil inlet 20 and the oil outlet 21 are communicated to work; after the electric power is applied, the electromagnetic force generated by the electromagnet assembly can enable the ejector rod 11 to move forwards, and after the ejector rod is ejected away from the oil drain ball valve seat 26, the ejector rod is continuously ejected onto the inlet ball valve seat 25 forwards to seal the oil inlet 20, so that the oil drain port is completely opened for oil drain action. The ports of the inlet ball valve seat 25 and the drain ball valve seat 26, which are in contact with the valve ball 24, are of conical surface structures, and the structures can be better in fit after being in contact with the valve ball 24, so that the sealing performance is effectively improved.
