[0017] The utility model will be further described in combination with the drawings and specific embodiments.

[0018] Referring to Figs. 1-3The technical scheme adopted by the embodiment is shown as follows: an explosion-proof and impact-resistant electromagnetic valve, comprising a valve body 1 and an electric control valve cover 3 detachably arranged on the top of the valve body 1, a magnet 5 fixedly arranged on the bottom of the electric control valve cover 3, a lifting rod 4 slidably arranged on the bottom surface of the electric control valve cover 3 and extending into the inner cavity of the valve body 1, a magnet valve plate 2 fixedly arranged on the bottom end of the lifting rod 4 and capable of closing the valve body 1, a reset spring 6 arranged between the top surface of the magnet valve plate 2 and the bottom surface of the electric control valve cover 3, an impact-resistant pipe 7 arranged on the bottom of the valve body 1, the impact-resistant pipe 7 comprising a water inlet pipe 71 arranged on one side of the valve body 1 and a water outlet pipe 72 arranged on the other side of the valve body 1, the water inlet pipe 71 and the water outlet pipe 72 being connected to each other, a pressure block 73 arranged at the connection position of the water inlet pipe 71 and the water outlet pipe 72, the pressure block 73 comprising a connecting block 731 arranged between the water inlet pipe 71 and the water outlet pipe 72 and a water inlet through hole 732 integrally formed in the connecting block 731, a contraction block 733 integrally formed on the inner wall of the water inlet through hole 732, a sliding groove 735 integrally formed in the connecting block 731 and connected to the end of the water inlet through hole 732, a shunt pipe 737 integrally formed on the side wall of the sliding groove 735, a drainage through hole 738 integrally formed on the end of the shunt pipe 737 and penetrating the connecting block 731, and a closing structure arranged on the inner wall of the sliding groove 735, the closing structure comprising a closing block 734 slidably arranged on the inner wall of the sliding groove 735, one end of the closing block 734 being in abutment with the contraction block 733, and a closing spring 736 arranged between the other end of the closing block 734 and the sliding groove 735. During use, the valve body 1 is installed on a pipeline, and then a current signal is input through the electric control valve cover 3. When the electric control valve cover 3 is powered, the magnet 5 generates a magnetic force, and the magnetic force attracts the magnet valve plate 2 to move upward together with the lifting rod 4, so that the valve body 1 is opened and water flows through the valve body 1, and the reset spring 6 is compressed to generate an elastic force. When the water flow needs to be disconnected, the current of the electric control valve cover 3 is disconnected, so that the magnetic force of the magnet 5 disappears, the reset spring 6 pushes the magnet valve plate 2 back, and the valve body 1 is closed to prevent the water flow. When the valve is closed, the water flow has a high impact force due to inertia. At this time, the impact water flow is introduced into the water inlet pipe 71 of the impact-resistant pipe 7, so that the water flow flows into the water inlet pipe 71 and pushes away the closing block 734 of the pressure block 73 by the impact force, so that the closing block 734 is pressed into the sliding groove 735 and connects the water inlet through hole 732, the shunt pipe 737 and the drainage through hole 738. Thus, the high-pressure water flow can pass through the impact-resistant pipe 7 to the other side of the valve body 1 to relieve the pressure, and after the pressure disappears, the closing block 734 is quickly restored to close the impact-resistant pipe 7.When the valve is normally opened or closed, the water flow pressure and impact force cannot cause the closing block 734 to slide greatly, so that it can always close the shunt pipe 737 to avoid water leakage, and thus the cracking of the inner wall of the valve body 1 caused by high-intensity impact can be avoided, and the service life of the electromagnetic valve is prolonged.

[0019] The valve body 1 is provided with connecting flanges 8 at both ends, which facilitates the installation of the valve body 1 in the pipeline.

[0020] The top end of the water inlet pipe 71 is provided with a first enlarged pipe 74, which facilitates the water inlet end of the water inlet pipe 71 to be introduced into the impact water flow to a greater extent, and further reduces the impact force on the valve body 1.

[0021] The top end of the water outlet pipe 72 is provided with a second enlarged pipe 75, which facilitates the water flow to be discharged through the second enlarged pipe 75 to reduce the water flow impact force at the drainage end, thereby reducing the impact damage to the other side of the valve body 1.

[0022] The working principle of the utility model is as follows: when the utility model is used, the valve body 1 is installed on the pipeline, and then the current signal can be input through the electric control valve cover 3, and under the condition that the electric control valve cover 3 is electrified, the electromagnet 5 can generate a magnetic force, and the magnetic force can attract the magnet valve plate 2 and make the magnet valve plate 2 move upward together with the lifting rod 4, and the valve body 1 is opened, so that the water flow can pass through the valve body 1, and the reset spring 6 is compressed, and generates an elastic force, and when the water flow needs to be disconnected at the end of use, the current of the electric control valve cover 3 is disconnected, and then the magnetic force of the electromagnet 5 disappears, so that the reset spring 6 pushes the magnet valve plate 2, and the valve body 1 is closed, so that the water flow cannot pass through, and when the valve is closed, the water flow has a high impact force due to inertia at the moment of closing, and at this time, the impact water flow can be introduced into the water inlet pipe 71 of the anti-impact pipe 7, and then the water flow can flow into the water inlet pipe 71 and press and open the closing block 734 of the pressure block 73, so that the closing block 734 is pressed into the sliding groove 735 and communicates the water inlet through hole 732, the shunt pipe 737 and the drainage through hole 738, so that the high-pressure water flow can pass through the anti-impact pipe 7 to the other side of the valve body 1 to relieve the pressure, and after the pressure disappears, the anti-impact pipe 7 is quickly closed by the closing block 734, and when the valve is normally opened or closed, the water flow pressure and impact force cannot cause the closing block 734 to slide greatly, so that it can always close the shunt pipe 737 to avoid water leakage, and thus the cracking of the inner wall of the valve body 1 caused by high-intensity impact can be avoided, and the service life of the electromagnetic valve is prolonged.
