Description

Technical Field

[0001] The utility model relates to a right-angle electromagnetic pulse valve, belonging to the technical field of electromagnetic pulse valves. Background Art

[0002] Pulse valve refers to a diaphragm valve that is controlled by a pilot valve such as an electromagnetic or pneumatic valve and can instantly open and close a high-pressure gas source to generate pulses. A traditional electromagnetic pulse valve includes an electromagnetic assembly, an armature, a valve cover, a valve body, and a diaphragm. When the electromagnetic assembly is energized, the armature and the diaphragm move upward, and gas enters from the inlet and exits from the outlet of the valve body. When the electromagnetic assembly is not energized, the armature moves downward under the action of the armature spring, and the diaphragm moves downward under the action of the compression spring, and the diaphragm seals the outlet of the valve body.

[0003] Patent No. CN202320164023.0 discloses an electromagnetic pulse valve, including an electromagnetic assembly, a valve cover, a valve body and a diaphragm. The valve cover is provided with a rear air chamber, a connecting hole and an air leakage hole. The valve cover is provided with a limiting convex ring. An air guide groove is formed between two adjacent limiting convex rings. The air guide groove, the connecting hole and the air leakage hole are connected. A compression spring is installed in the limiting convex ring, and the compression spring is respectively against the valve cover and the diaphragm. The limiting convex ring limits the position of the compression spring, improves the placement stability of the compression spring between the diaphragm and the rear air chamber, prevents it from tilting and bending, enables it to better act on the diaphragm, and improves the sealing of the electromagnetic pulse valve. A gap is also reserved between two adjacent limiting convex rings to form an air guide groove, and gas can enter the connecting hole and the air leakage hole through the air guide groove.

[0004] The disadvantage of the electromagnetic pulse valve disclosed above is that the diaphragm is used to achieve the sealing effect, which is prone to diaphragm wear, resulting in the failure to ensure the sealing performance. In addition, the wiring is convenient, the wires cannot be tightened, and poor contact is prone to occur. For this reason, we design a right-angle electromagnetic pulse valve. Utility Model Content

A reset spring 12 is fixedly installed at the bottom end of the fixed iron core 11. The bottom end of the reset spring 12 is connected to a moving iron core 13 movably connected to the hollow channel of the coil 10; one end of the moving iron core 13 extends to the inside of the valve cavity of the pulse valve body 1 and is provided with a conical guide head 14. An upper sealing expansion ring 15 and a lower extrusion sealing ring 16 are distributed on the surface of the conical guide head 14. The upper sealing expansion ring 15 and the lower extrusion sealing ring 16 are both connected to the valve seat through hole of the pulse valve body 1.

[0022] The above design has the advantages that the valve cavity through hole of the pulse valve body 1 can be better sealed, achieving a good sealing effect and preventing the wear of the diaphragm.
