Problems solved by technology

However, in high-pressure environments, the leakage of the medium will increase significantly, which will not only lead to slow response and low precision of the solenoid valve, but also cause cavitation or other problems of parts
[0003] When the solenoid valve in the prior art is in use, the valve body of the solenoid valve will expand outward under the action of fluid pressure in the inner cavity, causing the gap between the valve body and the valve core of the solenoid valve to become larger, which in turn leads to Poor sealing and large leakage

Embodiment 1

[0048] This embodiment provides an electromagnetic actuator, which can be used in a high-pressure environment, has good sealing performance, and reduces the probability of leakage.

[0049] Such as figure 1 As shown, the electromagnetic actuator includes a valve body 1 , a valve seat 2 and a valve core 3 .

[0050] Among them, such as figure 2 As shown, the valve body 1 has a connecting mounting hole 11 and a central hole 12 . The aperture of mounting hole 11 is greater than the aperture of middle hole 12, and mounting hole 11 is used for installing valve seat 2, that is, valve seat 2 is installed in mounting hole 11, in some embodiments, as figure 1 As shown, the cross section of the valve seat 2 is T-shaped, the bottom end of the valve seat 2 extends into the installation hole 11 , and the top end of the valve seat 2 is located outside the valve body 1 and cooperates with the top end of the valve body 1 . The valve seat 2 has a first through hole 21 communicating with th...

Embodiment 2

[0070] The difference between the electromagnetic actuator provided in this embodiment and the first embodiment is that the groove 13 in this embodiment is provided on the valve core 3 .

[0071] Specifically, such as Image 6 As shown, the valve core 3 is provided with a groove 13 communicating with the first through hole 21. The depth direction of the groove 13 is parallel to the extending direction of the valve body 1. The groove 13 is used to accommodate the high-pressure fluid so that the high-pressure fluid can squeeze out Press the spool 3 against the valve body 1.

[0072] Further, the spool 3 includes a large cylindrical section 31, a small cylindrical section 32 and a conical section 33 connected in sequence. The end surface of the large cylindrical section 31 connected to the small cylindrical section 32 is provided with a groove 13, and the high-pressure medium flows into it. When the groove 13 is formed, the groove wall of the groove 13 can be squeezed close to t...

Embodiment 3

[0075] The difference between the electromagnetic actuator provided in this embodiment and the embodiment is that grooves 13 are provided on both the valve body 1 and the valve core 3 in this embodiment.

[0076] Specifically, such as Figure 7 As shown, the spool 3 includes a large cylindrical section 31, a small cylindrical section 32 and a conical section 33 connected in sequence. The end surface of the large cylindrical section 31 connected to the small cylindrical section 32 is provided with a groove 13, and the middle hole 12 includes a large hole section 121 and a small hole section 122. The aperture of the large hole section 121 is larger than the aperture of the small hole section 122. The intersection of the large hole section 121 and the small hole section 122 forms a junction surface, and the junction surface is provided with the above-mentioned groove 13 . By arranging two grooves 13, the groove walls of the two grooves 13 are close to each other and closely atta...

Abstract

The invention discloses an electromagnetic actuator and an electromagnetic actuating system, and belongs to the technical field of electromagnetic valves.The electromagnetic actuator comprises a valve body, a valve seat and a valve element, the valve body is provided with a mounting hole and a middle hole which are communicated, and the hole diameter of the mounting hole is larger than that of the middle hole; the valve seat is mounted in the mounting hole, and the valve seat is provided with a first through hole communicated with the middle hole; a valve element is movably arranged in the middle hole in a penetrating mode, and one end of the valve element can abut against the valve seat and seal the first through hole. A groove communicated with the first through hole is formed in the valve body and / or the valve element, the depth direction of the groove is parallel to the extending direction of the valve body, and the groove is used for containing high-pressure fluid so that the high-pressure fluid can extrude the valve element to abut against the valve body or extrude the valve body to abut against the valve element. The electromagnetic actuator and the electromagnetic execution system provided by the invention have good sealing performance, and the probability of leakage is reduced.

Description

technical field [0001] The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic actuator and an electromagnetic actuator system. Background technique [0002] With the development of digitization and electrification, all walks of life are developing towards intelligence, which requires sensors to collect signals and states, and actuators to achieve a series of precise operations. Solenoid valve is a kind of actuator, mainly used for the control of liquid pressure and flow, and has significant advantages. With the gradual improvement of the precision of mechanical equipment, the pressure of the medium used is also higher and higher, and the requirements for control precision are also higher and higher. However, in a high-pressure environment, the leakage of the medium will increase significantly. The leakage will not only lead to slow response and low precision of the solenoid valve, but also cause cavitation of parts or oth...
