[0002] Solenoid valves are used as control elements in various environments and cover a wide range of areas. The main mechanism is that after power is turned on, the magnetic field generated by the coil can magnetize the iron core, and the dynamic and static iron cores are attracted together. After power is turned off, the magnetic field disappears, and under the action of spring force and pressure difference force, the dynamic and static iron cores are separated.

[0003] Normally, the working pressure of the solenoid valve is in a high-pressure environment of 3MP, so preventing leakage is the core indicator of the solenoid valve. In related technologies, the conventional way to seal the support seat and the valve seat of the solenoid valve is to use a sealing ring. When the support seat needs to be flipped during the assembly process, the sealing ring is very easy to fall off, making it difficult to realize the automation of the solenoid valve assembly.

Among them, the inclined surface 111 can be constructed in any suitable form, and the present disclosure does not make any specific restrictions on this. As an exemplary embodiment, the support seat 100 has a first end face 131 and a second end face 132 relative to each other, and the mounting hole 110 may include a mating hole section, the aperture of which may gradually decrease from the first end face 131 toward the second end face 132 to form an inclined surface 111, thereby providing oblique pressure to the seal 300.

[0034] In the valve body assembly provided in the present disclosure, the valve seat 200 can be constructed in any suitable form to achieve cooperation with the support seat 100, and the present disclosure does not impose any specific limitation on this. Figure 3 As shown in , the valve seat 200 includes a main body portion 210 and a matching portion 220 connected to each other. The main body portion 210 may have a contact surface 211, and the contact surface 211 may be opposite to the notch of the receiving groove 120. The matching portion 220 may be formed with a fitting surface 221. The sealing member 300 and the groove wall 121 of the receiving groove 120, the contact surface 211 and the fitting surface 221 are all in contact with each other. That is, when the sealing member 300 is installed in the receiving groove 120, the contact surface 211 and the receiving groove are in contact with each other. The grooves of 120 are opposite to each other, so as to provide a pressure toward the inside of the receiving groove 120 for the seal 300, thereby limiting the radial direction of the seal 300; in addition, a portion of the fitting surface 221 fits with the inclined surface 111, and the other portion extends to the receiving groove 120 and abuts against the seal 300, so as to provide an oblique pressure for the seal 300, thereby limiting the radial and axial directions of the seal 300, and further fixing the seal 300 in the receiving groove 120.

[0035] In the present disclosure, the receiving groove 120 is provided below the inclined surface 111, and the valve seat 200 is provided with a fitting surface 221 that fits the inclined surface 111 and abuts against the seal 300, and an abutting surface 211 that is opposite to the notch, so as to jointly press the seal 300 into the receiving groove 120, thereby completing the installation limit of the seal 300. In some other embodiments, the receiving groove 120 may also be provided on the inclined surface 111, that is, a portion of the inclined surface 111 is recessed from the inner wall of the mounting hole 110 toward the support seat 100 to form the receiving groove 120, so that when the valve seat 200 is installed in the mounting hole 110, the fitting surface 221 can press the seal 300 into the receiving groove 120 while fitting with the inclined surface 111, that is, the installation limit of the seal 300 is completed by the inclined surface 111 and the fitting surface 221, and the present disclosure does not make any specific restrictions on this.

Under normal circumstances, the valve seat 200 and the mounting hole 110 need to be tightly matched to ensure the air tightness between the two. On the basis of the sealing member 300 being accommodated in the accommodating groove 120, the setting of the chamfered surface 212 and the fitting surface 112 can avoid the deformation of the sealing member 300 or falling out of the accommodating groove 120 caused by the surface contact between the valve seat 200 and the support seat 100 as much as possible during the process of the valve seat 200 being installed into the support seat 100, thereby improving the reliability of the installation of the sealing member 300.

[0037] In the valve seat 200 assembly provided in the present disclosure, the valve seat 200 and the support seat 100 can be connected together in any suitable manner, and the present disclosure does not impose any specific limitation on this.

In this way, when the valve seat 200 needs to be installed on the support seat 100, the main body 210 of the valve seat 200 can be provided with an external thread, and the mounting hole 110 of the support seat 100 can be provided with an internal thread. It is only necessary to insert the main body 210 of the valve seat 200 into the mounting hole 110, and connect the two together through the cooperation of the internal and external threads, so as to realize the detachable connection between the support seat 100 and the valve seat 200.

[0038] In the valve seat 200 assembly provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 4As shown in , the mating part may be provided with a flange 230, and the flange 230 may overlap the end surface of the support seat 100 close to the valve seat 200. In this way, when the valve seat 200 is installed on the support seat 100, the provision of the flange 230 can enable the support seat 100 to provide a certain support for the valve seat 200, so as to improve the reliability of the installation of the valve seat 200.

[0039] In the valve seat 200 assembly provided in the present disclosure, as an exemplary embodiment, the flange platform 230 can be configured in any suitable shape to facilitate the installation of the valve seat 200, and the present disclosure does not impose any specific restrictions on this. As an exemplary embodiment, refer to Figure 4 As shown in the figure, the flange platform 230 can be constructed as a polygonal platform and has multiple first operating surfaces 231. The support seat 100 may include an operating portion 140, and the operating portion 140 is formed with multiple second operating surfaces 141. The flange platform 230 is overlapped with the operating portion 140 to achieve the purpose of the support seat 100 supporting the valve seat 200. In addition, due to the threaded connection between the valve seat 200 and the support seat 100, the setting of the flange platform 230 can be used as an operating portion for installing the valve seat 200. A disassembly tool compatible with the flange platform 230 is used to drive the flange platform 230, that is, the valve seat 200 to rotate until the flange platform 230 overlaps with the first end surface 131, and the installation of the valve seat 200 is completed.

[0040] As an exemplary embodiment, reference is made to Figure 4As shown in the figure, multiple first operating surfaces 231 and multiple second operating surfaces 141 can be arranged in the same plane in a one-to-one correspondence. Usually, the outside of the support seat 100 is provided with an external thread, and the operating portion 140 is used to cooperate with the disassembly tool to facilitate fixing the support seat 100 on the external structure. The corresponding coplanar arrangement of the first operating surface 231 and the second operating surface 141 can enable the installation between the valve seat 200 and the support seat 100 and the installation between the support seat 100 and the external structure to be completed by the same disassembly tool. In the present disclosure, the operating portion 140 of the support seat 100 is constructed as an operating table with a hexagonal cross-section. Correspondingly, the flange platform 230 of the valve seat 200 also has a hexagonal cross-section with the same size as the operating table. In this way, when it is necessary to complete the installation between the valve seat 200 and the support seat 100 and the support seat 100 and the external structure, a hexagonal sleeve is used as a disassembly tool and is sleeved on the outside of the flange platform 230.
