[0020] In an embodiment of the present utility model, those skilled in the art should note that the solenoid valves, valve plates, etc. involved in the present utility model can be regarded as prior art.

[0021] Preferred embodiment.

[0022] As Figures 1-3 shown, the present utility model discloses an electromagnetic pulse release and manual setting device, which includes a fixing unit 110 and an operating unit 120, wherein:

[0023] The fixing unit 110 includes a fixed iron core 111, a coil mounting seat 112, a coil 113 and a wire package seat 114. The fixed iron core 111 includes an integrally formed iron block body 1111 and a tube sleeve 1112. The coil mounting seat 112 is sleeved on the fixed iron core 111 and the coil 113 is installed on the coil mounting seat 112. The wire package seat 114 surrounds the coil 113 and the fixed iron core 111;

[0024] The operating unit 120 includes a moving iron core 121, a moving shaft 122, a first spring mounting seat 123, a first spring 124, a handle 125 and a plurality of steel balls 126. The moving iron core 121 is disposed inside the tube sleeve 1112 and the moving shaft 122 sequentially penetrates through the moving iron core 121 and the iron block body 1111 from top to bottom. The first spring mounting seat 123 is sleeved on the moving shaft 122 and the bottom end of the first spring mounting seat 123 is installed on the iron block body 1111. The first spring mounting seat 123 is provided with a plurality of steel ball mounting holes 1231. The steel balls 126 are installed in the steel ball mounting holes 1231. One end of the first spring 124 is installed on the first spring mounting seat 123 and the other end of the first spring 124 abuts against the moving iron core 121. The handle 125 is installed at the top end of the moving shaft 122;

[0025] The moving iron core 121 is provided with a first groove portion 1211 and the moving shaft 122 is provided with a second groove portion 1221. The directions of the first groove portion 1211 and the second groove portion 1221 are opposite.

[0026] Specifically, a central shaft nut 1222 is provided at the top of the moving shaft 122. The handle 125 is sleeved on the top of the moving shaft 122 and a first limiting block 1251 is provided inside the handle 125.

[0027] More specifically, a magnetic isolation sheet 1113 is provided at one end of the iron block body 1111 close to the moving iron core.

[0028] Furthermore, the coil 113 is connected to a wire 1131.

[0029] Furthermore, a valve plate (used to close the through hole of the solenoid valve) is installed at the bottom of the movable shaft 122.

[0030] For this utility model:

[0031] like Figure 2 As shown, the device is in an open state, that is, the solenoid valve is in an open state, and the gas flows normally. The steel ball is located in the steel ball installation hole and at the same time, the second groove portion of the movable shaft is stuck, so that the movable shaft will not move downward due to its own gravity, thereby not driving the valve plate to move downward to close the gas through hole of the solenoid valve. When the solenoid valve needs to be closed in an emergency, the coil is energized through the wire, thereby combining with the fixed iron core to generate electromagnetic force, so that the moving iron core moves downward, so that the first groove portion moves downward, so that the steel ball will move to the first groove portion and break away from the restriction on the second groove portion, so that the movable shaft can move downward (due to gravity and other drives, etc.), thereby driving the valve plate to move downward to close the gas through hole of the solenoid valve, as shown in FIG. Figure 3 As shown;

[0032] When it is necessary to open (it must be opened manually because it is necessary to observe the on-site environment before making a judgment), the handle is forced upward, and the handle moves upward until the first limit block abuts against the central axis nut, thereby driving the movable shaft to move upward, so that the valve plate moves upward, and the through hole is opened; and when the second groove portion moves upward to the steel ball position, due to the compression force of the compression spring, the top end of the compression spring will lift the moving iron core upward, so that the cross section of the first groove portion pushes the steel ball to move toward the second groove portion, so that the steel ball is stuck in the second groove portion, and the movable shaft is fixed and will not move downward;

[0033] The utility model can also be closed manually by applying force downward to the handle so that the handle drives the moving iron core to move downward, so that the first groove part moves downward.

[0034] It is worth mentioning that the technical features such as the solenoid valve and valve plate involved in this utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0035] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
