[0002] The pulse solenoid valve is a type of solenoid valve, also known as a diaphragm valve. The pulse signal is input into the coil inside the solenoid valve body through a wire. The pulse valve is controlled by the output signal of the pulse injection controller. The pressure changes in the two air chambers before and after the valve cause the rubber diaphragm to flex and deform to achieve the opening and closing of the pulse valve.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to facilitate the addition of auxiliary connection mechanisms, the pulse solenoid valve and the connecting pipe are auxiliary connected by flipping and clamping, thereby improving the use effect. Figure 1-3 As shown, a pulse solenoid valve described in the utility model comprises a main body 1, a manual component 4 and a limit component 5, wherein an electromagnet component 2 is arranged on the top of the main body 1, both ends of the main body 1 are connected with a fixing flange 3 by welding, a manual component 4 is arranged on one side of the main body 1, and the periphery of the fixing flange 3 is rotatably connected with the limit component 5;

[0031] The limiting assembly 5 includes an L-shaped clamping plate 501 , both sides of which are connected to a rotating shaft 502 via bolts, and a coil spring 503 is sleeved on the outer periphery of the rotating shaft 502 .

[0032] When in use, elastic deformation can be utilized through the L-shaped clamping plate 501, the rotating shaft 502 and the coil spring 503. During the installation process, the rotating clamping is utilized to perform auxiliary limiting processing, thereby improving the convenience and stability of the installation operation.

[0033] The electromagnet assembly 2 includes a static iron core, a spring, a moving iron core, and a coil support.

[0034] The main body 1 includes a diaphragm assembly.

[0035] In order to improve the flexibility of use in emergency situations, for example, Figure 1 , Figure 4As shown, the utility model also includes that the hand-operated component 4 includes a mounting seat 401, a valve stem 402 is threadedly connected to the mounting seat 401, and the valve stem 402 passes through the main body 1, and a valve plate 403 is bolted to one end of the valve stem 402 in the main body 1.

[0036] When in use, a manual opening and closing mechanism can be added by installing the seat 401, the valve stem 402, and the valve plate 403, thereby increasing the flexibility of using the pulse solenoid valve in emergency situations such as power failure.

[0037] For example, Figure 3 As shown, the utility model further includes that a ball groove 504 is formed on the inner surface of the L-shaped clamping plate 401 , and a ball 505 is rollingly connected in the ball groove 504 .

[0038] When in use, the ball groove 504 and the ball 505 facilitate the fixing flange 301 during the fixed connection operation, thereby improving the convenience of rotation.

[0039] For example, Figure 2 As shown, the utility model also includes that the periphery of the fixing flange 3 is connected to the fixing seat 301 by bolts, and the L-shaped clamping plate 501 is rotatably connected to the fixing seat 301 by a rotating shaft 502, one end of the coil spring 503 is connected to the rotating shaft 502 by welding, and the other end of the coil spring 503 is connected to the fixing seat 301 by a slot.

[0040] When in use, the fixing seat 301 is used to facilitate auxiliary connection between the limiting assembly 5 and the fixing flange 3 .

[0041] For example, Figure 1 As shown, the utility model also includes that the main body 1 includes a U-shaped tube 101 , and the main body 1 is connected to the U-shaped tube 101 .

[0046] When in use, the mounting hole 302 facilitates the fixing flange 3 to dock with the pipeline for fixed connection.

[0047] When the utility model is used, the operator can first flip the L-shaped clamping plate 501 outward during the installation operation, and use the elastic deformation of the coil spring 503 to drive the rotating shaft 502 to rotate, so that the L-shaped clamping plate 501 clamps the connecting pipe, which plays an auxiliary limit clamping effect, thereby improving the convenience and stability of the installation operation, and then rotate the main body 1 or the connecting pipe to align the installation hole 302, and use the rolling contact of the ball 505 to greatly reduce the friction generated by the rotation, further greatly improving the flexibility of the installation operation;

[0048] When the pulse solenoid valve is operating and it is difficult to open the main body 1 due to power failure, the hand wheel 404 can be manually rotated to drive the valve stem 402 and the valve plate 403 to rotate, so that a passage is formed in the U-shaped tube 101 to facilitate temporary passage of materials, greatly improving the flexibility of use in emergency situations.
