Example 1

With reference to fig. 1-4, the present invention provides an electromagnetic valve set, comprising:

the valve comprises a valve body 1, wherein a first channel 11, a second channel 12 and a third channel 13 which are communicated with each other are sequentially arranged in the valve body 1;

the valve sleeve 2 is positioned in the channel II 12, and a channel IV 21 is arranged in the valve sleeve 2;

the valve core 3 is positioned in the valve sleeve 2, and a channel five 31 is arranged in the valve core 3;

wherein, the channel four 21 is communicated with the channel two 12 and the channel five 31, the channel five 31 is communicated with the channel three 13, the valve core 3 is connected with the valve body 1 through the spring 10, and the side of the valve sleeve 2 close to the channel one 11 is provided with the filter assembly 4.

Specifically, hydraulic oil firstly flows through the first channel 11 of the valve body 1, flows through the second channel 12 of the valve body 1, simultaneously flows through the filter assembly 4, then flows through the fourth channel 21 of the valve sleeve 2, and generates pressure on the valve core 3, so that the valve core 3 moves towards the third channel 13 of the valve body 1, meanwhile, the valve core 3 generates pressure on the spring 10, so that the spring 10 is compressed, at the moment, the pressure is greater than the elastic force, meanwhile, the hydraulic oil flows through the fifth channel 31 of the valve core 3, and finally flows through the third channel 13 of the valve body 1, and one-way conduction is realized;

when oil feeding is stopped in the first channel 11, the pressure of the hydraulic oil on the valve core 3 is reduced, at the moment, the elastic force is larger than the pressure, the spring 10 restores to the original state and pushes the valve core 3 to move towards the first channel 11 of the valve body 1, the valve core 3 is enabled to be in contact with the valve sleeve 2, and the pressure maintaining effect is achieved on the first channel 11 and the second partial channel 12 of the valve body 1.

The filter assembly 4 can filter impurities and foreign matters in the hydraulic oil, and prevent the impurities and the foreign matters from damaging the valve core 3, so that when the valve core 3 is contacted with the valve sleeve 2, a gap still exists, and further, both the one-way conduction and the pressure maintaining function are invalid, so that the valve core 3 can be effectively protected by the filter assembly 4; the first channel 11, the second channel 12 and the third channel 13 are used for passing through hydraulic oil and are communicated with each other, so that the hydraulic oil is ensured to smoothly circulate; the second channel 12 is also used for accommodating the valve sleeve 2, the valve core 3 and the spring 10; and the fourth 21 and fifth 31 passages are for passage of hydraulic oil.

Specifically, the filter assembly 4 includes more than two filter layers 41, which is beneficial to increasing the filtering capacity and effectively removing impurities and foreign matters in the hydraulic oil.

Specifically, along the electromagnetic valve set conduction direction, the mesh size of the filter layer 41 decreases progressively.

Wherein, the great filter layer 41 in mesh of filter component 4 is got rid of bulky impurity and foreign matter earlier, and the less impurity of volume and foreign matter are got rid of again to the less filter layer 41 in mesh of filter component 4, and the multilayer filters step by step, further increases filtering capability, effectively gets rid of impurity and foreign matter in the hydraulic oil.

Specifically, the material of the filter layer 41 is glass fiber or porous ceramic.

The glass fiber has elasticity, low pressure loss and good capture rate for impurities and foreign matters; the porous ceramic has high porosity and high filtering precision.

In particular, the connection between adjacent filter layers 41 of filter assembly 4 is a nested connection.

Wherein the nesting connection ensures that adjacent filter layers 41 are connected tightly, thereby preventing adjacent filter layers 41 from becoming detached from each other, resulting in failure of filter assembly 4.

The hydraulic oil firstly flows through the first channel 11 of the valve body 1, then flows through the second channel 12 of the valve body 1, then flows through the sixth channel 61 of the fastening component 6, then flows through the filter component 4, and finally flows through the fourth channel 21 of the valve sleeve 2, wherein the fastening component 6 is used for fixing the filter component 4, so that the filter component 4 compresses the valve sleeve 2, and the stability of the filter component 4 and the valve sleeve 2 is improved.

Specifically, the oil inlet assembly 7 and the oil outlet assembly 8 are further included, the oil inlet assembly 7 is communicated with one end, away from the second passage 12, of the first passage 11, and the oil outlet assembly 8 is communicated with one end, away from the second passage 12, of the third passage 13.

Specifically, the working principle is as follows: the hydraulic oil flows into the first channel 11 of the valve body 1 from the oil inlet assembly 7, passes through the second channel 12 of the valve body 1, flows through the sixth channel 61 of the fastening assembly 6, then flows through the filtering assembly 4, is subjected to multi-layer filtering by the filtering assembly 4, is cleaned of impurities and foreign matters in the hydraulic oil, flows through the fourth channel 21 of the valve sleeve 2, and generates pressure on the valve core 3, so that the valve core 3 moves towards the third channel 13 of the valve body 1, meanwhile, the valve core 3 generates pressure on the spring 10, so that the spring 10 is compressed, at the moment, the pressure is greater than the elastic force, meanwhile, the hydraulic oil flows through the fifth channel 31 of the valve core 3, finally flows through the third channel 13 of the valve body 1, and flows out through the oil outlet assembly 8, and one-way conduction is achieved.

When the oil inlet assembly 7 stops oil inlet, the pressure of the hydraulic oil on the valve core 3 is reduced, at the moment, the elastic force is larger than the pressure, the spring 10 restores to the original state and pushes the valve core 3 to move towards the first channel 11 of the valve body 1, the valve core 3 is enabled to be in contact with the valve sleeve 2, and the reverse pressure maintaining effect is achieved on the first channel 11 of the valve body 1, the second partial channel 12 and the sixth channel 61 of the fastening assembly 6.
