For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Refer to the following Figure 1and Figure 2 A bidirectional electromagnetic stop valve according to some embodiments of the present application is described.

[0040] The present application provides a two-way electromagnetic stop valve, such as Figure 1 As shown, the two-way electromagnetic stop valve includes a valve body 1, a drive assembly, a first sealing member 2, a second sealing member 3 and a transmission member.

[0041] A valve cavity is formed in the valve body 1, and the valve cavity penetrates the valve body 1 at both ends in the axial direction of the valve body 1 to form openings at both ends in the axial direction of the valve body 1 for fluid to enter and exit the valve body 1. The opening at one end of the valve body 1 is recorded as a first opening, and the opening at the other end is recorded as a second opening; the first sealing member 2 is arranged at the first opening, and the second sealing member 3 is arranged at the second opening. Both the first sealing member 2 and the second sealing member 3 can move along the axial direction of the valve body 1 to approach the valve body 1 or move away from the valve body 1.

[0042] For the first sealing member 2, when the first sealing member 2 moves to the first position in the direction close to the valve body 1, the first sealing member 2 can seal the first opening, that is, close the first opening; when the first sealing member 2 moves in the direction away from the valve body 1 and leaves the first position, the first sealing member 2 can release the seal on the first opening, that is, open the first opening.

[0043] For the second sealing member 3, when the second sealing member 3 moves to the second position in the direction close to the valve body 1, the second sealing member 3 can seal the second opening, that is, close the second opening; when the second sealing member 3 moves in the direction away from the valve body 1 and away from the second position, the second sealing member 3 can release the seal on the second opening, that is, open the second opening.

[0044] The transmission member is arranged inside the valve body 1, and the first seal 2 and the second seal 3 are matched through the transmission member, so that the second seal 3 and the second seal 3 can synchronously approach or move away from the valve body 1; the driving component is used to drive the first seal 2 and the second seal 3 to move. Under the drive of the driving component, when the first seal 2 moves to the first position, the second seal 3 synchronously moves to the second position, so that the first opening and the second opening of the valve body 1 are closed at the same time; when the first seal 2 leaves the first position, the second seal 3 synchronously leaves the second position, so that the first opening and the second opening of the valve body 1 are opened at the same time.

[0045] Therefore, when the valve body 1 is in a conducting state, the first opening and the second opening are both in an open state, and the fluid can flow into the valve body 1 from the first opening and then flow out from the second opening, or flow into the valve body 1 from the second opening and then flow out from the first opening. Therefore, when the two-way electromagnetic stop valve of the present application is installed in a fluid delivery pipeline, the installation direction of the valve body 1 does not need to be considered, that is, the first opening can be used as the inlet of the valve body 1 and the second opening can be used as the outlet of the valve body 1, or the second opening can be used as the inlet of the valve body 1 and the first opening can be used as the outlet of the valve body 1. Therefore, the leakage problem of the valve body 1 and the difficulty in troubleshooting caused by the misalignment of the installation direction are avoided.

[0046] In one embodiment of the present application, preferably, valve covers are provided at both ends of the valve body 1 in the axial direction. For example, the valve cover at the end of the valve body 1 with the first opening is the first valve cover 4, and the valve cover at the end of the valve body 1 with the second opening is the second valve cover 5.

[0047] The first valve cover 4 forms a first chamber, and the first chamber is connected to the first opening of the valve body 1. At the same time, the first valve cover 4 is provided with a fluid interface, namely the first fluid interface 41, for fluid to enter and exit the first chamber. The first sealing member 2 is arranged between the first valve cover 4 and the valve body 1, specifically, in the first chamber; when the first opening is in an open state, the first fluid interface 41 is connected to the valve body 1, and when the first opening is blocked by the first sealing member 2, the connection between the first fluid interface 41 and the valve body 1 is cut off.

[0048] The second valve cover 5 forms a second chamber, and the second chamber is connected to the second opening of the valve body 1. At the same time, the second valve cover 5 is also provided with a fluid interface, namely, a second fluid interface 51, for fluid to enter and exit the second chamber. The second sealing member 3 is arranged between the second valve cover 5 and the valve body 1, specifically, in the second chamber; when the second opening is in an open state, the second fluid interface 51 is connected to the valve body 1, and when the second opening is blocked by the second sealing member 3, the connection between the second fluid interface 51 and the valve body 1 is cut off.

[0049] When the bidirectional electromagnetic stop valve of the present application is installed in a fluid delivery pipeline, the valve body 1 is specifically connected to the external fluid delivery pipeline through the fluid interface on the first valve cover 4 and the fluid interface on the second valve cover 5 .

[0050] In one embodiment of the present application, preferably, the inner wall of the valve body 1 is formed with an incline at the first opening and the second opening, and the first seal 2 and the second seal 3 are formed with an arc surface, and when the first seal 2 moves to the first position, the arc surface of the first seal 2 abuts against the incline at the first opening to form a line sealing structure, thereby sealing the first opening through the first seal 2; when the second seal 3 moves to the second position, the arc surface of the second seal 3 abuts against the incline at the second opening to form a line sealing structure, thereby sealing the second opening through the second seal 3.

[0051] In one embodiment of the present application, preferably, the transmission member is a transmission gear 8, and the transmission gear 8 is rotatably arranged in the valve body 1 around its own axis, and the axis of the transmission gear 8 is perpendicular to the axis of the valve body 1. The first seal 2 and the second seal 3 are both provided with transmission racks, for example, the transmission rack on the first seal 2 is a first rack, and the transmission rack on the second seal 3 is a second rack, and the length directions of the first rack and the second rack are both along the axial direction of the valve body 1, the first rack extends to one side of the radial direction of the transmission gear 8 and meshes with the transmission gear 8, and the second rack extends to the other side of the radial direction of the transmission gear 8 and meshes with the transmission gear 8, so that through the transmission gear 8, the first rack and the second rack can also enable the first seal 2 and the second seal 3 to move in opposite directions along the axial direction of the valve body 1, for example, in Figure 1 When the first sealing member 2 moves downward toward the valve body 1 to the first position, the second sealing member 3 moves upward toward the valve body 1 to the second position; when the first sealing member 2 moves upward away from the valve body 1 to leave the first position, the second sealing member 3 moves downward away from the valve body 1 to leave the second position.

[0052] In one embodiment of the present application, preferably, the driving assembly includes an electromagnetic coil 7, a static iron core and a moving iron core 6; a sleeve portion is provided on the first valve cover 4, one end of the moving iron core 6 is connected to the first sealing member 2, and the other end of the moving iron core 6 is movably inserted into the sleeve portion along the axial direction of the valve body 1, the static iron core is provided on the sleeve portion, and the static iron core and the moving iron core 6 are arranged opposite to one end away from the first sealing member 2, the electromagnetic coil 7 is arranged around the outer side of the sleeve portion, and the electromagnetic coil 7 can pass current. When the electromagnetic coil 7 is energized, a magnetic force can be generated between the static iron core and the moving iron core 6 to move the moving iron core 6 toward the static iron core, thereby driving the first sealing member 2 away from the valve body 1 through the moving iron core 6, so that the first sealing member 2 releases the blockage of the first opening of the valve body 1, and at the same time, the first sealing member 2 moves away from the valve body 1, and under the transmission of the transmission gear 8, the second sealing member 3 also moves in a direction away from the valve body 1 to release the blockage of the second opening.

[0053] In this embodiment, preferably, the drive assembly also includes a first elastic member 9, which is arranged between the first valve cover 4 and the first sealing member 2, and the two ends of the first elastic member 9 are respectively against the first valve cover 4 and the first sealing member 2, and the first elastic member 9 can provide elastic force for the first sealing member 2, so that the first sealing member 2 has a tendency to move toward the valve body 1, so that when the electromagnetic coil 7 is powered off, the magnetic force between the static iron core and the moving iron core 6 disappears, and the first sealing member 2 can move toward the valve body 1 under the action of the elastic force of the first elastic member 9 until the arc surface of the first sealing member 2 is against the inverted inclined surface at the first opening of the valve body 1, at which time the first sealing member 2 moves to the first position to seal the first opening; at the same time, under the transmission of the transmission gear 8, the second sealing member 3 moves to the second position to seal the second opening.

[0054] In this embodiment, preferably, the drive assembly also includes a second elastic member, which is arranged between the second valve cover 5 and the second sealing member 3, and the two ends of the second elastic member are respectively abutted against the second valve cover 5 and the second sealing member 3, and the second elastic member can provide elastic force for the second sealing member 3, so that the second sealing member 3 has a tendency to move toward the valve body 1, so that when the electromagnetic coil 7 is powered off, the magnetic force between the static iron core and the moving iron core 6 disappears, and the elastic force provided by the second elastic member to the second sealing member 3 can make the second sealing member 3 move toward the valve body 1 to the second position to seal the second opening, and at the same time, under the transmission of the transmission gear 8, the first sealing member 2 moves to the first position.

[0055] It should be noted that the driving assembly may include either the first elastic member 9 or the second elastic member, or may include both of them.

[0056] In this embodiment, preferably, when the driving assembly includes the first elastic member 9 , the first elastic member 9 is sleeved on the moving iron core 6 to ensure that the elastic force provided by the first elastic member 9 to the first sealing member 2 can be along the axial direction of the valve body 1 .

[0057] Preferably, when the driving assembly includes a second elastic member, a limiting column 31 is provided on the side of the second sealing member 3 facing the second valve cover 5, the length direction of the limiting column 31 is along the axial direction of the valve body 1, and the second elastic member is sleeved on the limiting column 31, so that the limiting column 31 ensures that the elastic force provided by the second elastic member to the second sealing member 3 can be along the axial direction of the valve body 1.

[0059] The first transmission column 21 and the second transmission column can be inserted into the valve body 1, and the outer diameters of the first transmission column 21 and the second transmission column are adapted to the inner diameter of the valve body 1, so that the first transmission column 21 and the second transmission column are both clearance-matched with the valve body 1, thereby not affecting the reciprocating motion of the first seal 2 and the second seal 3, and ensuring that the movement of the first seal 2 and the second seal 3 is always carried out along the axial direction of the valve body 1 without deflection.

[0061] Furthermore, combined with Figure 1 As shown, when the arc surface of the first seal 2 abuts against the inverted slope of the valve body 1 to form a line seal, an annular sealing line is formed between the two, and similarly, an annular sealing line is also formed between the arc surface of the second seal 3 and the inverted slope of the valve body 1; the circumference of the outer edges of the multiple flow channel grooves 11 is located inside the two sealing lines, so that the multiple flow channels running through the two ends of the valve body 1 will not destroy the line sealing structure between the first seal 2, the second seal 3 and the valve body 1.
