Description

Technical Field

[0001] The utility model relates to the field of electromagnetic valves, in particular to a universal explosion-proof electromagnetic valve device. Background Art

[0002] The explosion-proof solenoid valve is a device that encloses all the parts that may ignite explosive gas mixtures in a shell. The explosion-proof shell separates the internal space of the equipment from the surrounding environment and will not cause ignition of the external explosive environment formed by one or more gases or vapors, thereby ensuring the safety of the solenoid valve.

[0003] Although the existing solenoid valve is provided with a flameproof casing, the interior of the flameproof casing lacks a structure to buffer the shock wave of the explosion energy. The flameproof casing may be punctured after multiple flameproofing. A mining flameproof solenoid valve with application number 202123436667.0 has a certain buffering effect on the explosion energy, but it does not guide the shock wave, and the explosion energy is difficult to enter the small hole, and its buffering effect is limited. Therefore, it is necessary to design a universal flameproof solenoid valve device that can better guide and buffer the explosion energy and extend the service life of the flameproof casing. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a universal flameproof solenoid valve device to solve the technical problem of lack of guide buffering.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a universal explosion-proof solenoid valve device, comprising a shell, a buffer assembly is arranged in the shell, the buffer assembly includes a buffer plate, and a connecting rod is fixed to one side of the buffer plate, a spring 1 is sleeved on the outside of the connecting rod, and a slide plate is connected to the top of the buffer plate, a spring 2 is connected between the slide plate and the buffer plate, and a guide plate is fixed in the shell, a counter-attack chamber is fixed on the shell, and a buffer pad is arranged in the counter-attack chamber, guide grooves are opened in the guide plate, the guide grooves are connected with baffles, a torsion spring is connected to the baffle, and a limiting plate is fixed in the guide groove.

[0006] By adopting the above technical solution, as the slide plate moves, the guide grooves on the guide plate are gradually exposed, and the explosion energy enters each guide groove and then enters the counterattack chamber. The explosion energy on both sides is offset and reduced in the counterattack chamber, and the buffer pad can buffer the explosion energy in the counterattack chamber and reduce the impact force received by the counterattack chamber.

[0007] Furthermore, an electromagnetic control body is installed in the shell, and a valve body is connected to the electromagnetic control body.

[0008] By adopting the above technical solution, the staff can connect the universal explosion-proof solenoid valve device to the pipeline through the valve body to form a passage, and the staff can control the opening and closing of the valve body through the electromagnetic control body, thereby controlling the connectivity of the pipeline.

[0009] Furthermore, two buffer plates are provided, and the two buffer plates are slidably connected to the shell respectively.

[0010] By adopting the above technical solution, when an explosion occurs, the explosion shock wave bombards the buffer plate, and the explosion energy can be buffered by the cooperation of the buffer plate and the spring, and the connecting rod guides the buffer plate during the process.

[0011] Furthermore, two slide plates are provided, and the two slide plates are slidably connected to two buffer plates respectively.

[0012] By adopting the above technical solution, when the buffer plate moves away from the valve body, since the two slide plates are slidingly connected to the two buffer plates respectively, the slide plate can cooperate with the spring 2 to further buffer the explosion energy and reduce the impact force on the buffer plate.

[0013] Furthermore, two guide plates are provided, and the bottoms of the two guide plates are both sloped.

[0014] By adopting the above technical solution, during the explosion process, the buffer plate is forced to move away from the valve body. Since the bottoms of the two guide plates are sloped, the slide plate can be continuously moved downward under the guidance of the guide plates to squeeze the spring 2 for buffering.

[0015] Furthermore, the baffle plates and guide grooves are provided in plurality, and the plurality of baffle plates and guide grooves are divided into two groups, and each group of the baffle plates is rotatably connected to each group of the guide grooves.

[0016] By adopting the above technical solution, after the explosion shock wave enters the impact chamber through the guide groove, the baffle can cooperate with the torsion spring and the limit plate to form a one-way valve-like structure to prevent the explosion energy from returning to the shell, thereby further protecting the shell.

[0017] Furthermore, the valve body is in an "n" shape.

[0018] By adopting the above technical solution, during the movement of the buffer plate, the valve body is in an "n" shape, which not only ensures the smooth connection between the valve body and the pipeline, but also ensures that the movement stroke of the buffer plate is sufficient, so that the buffering effect of the device is guaranteed.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model buffers the explosion energy through the arrangement of a buffer component, wherein the buffer plate and the spring 1 cooperate to buffer the explosion energy. During the process, the connecting rod guides the buffer plate, and the buffer plate is forced to stay away from the valve body, and then the slide plate continuously moves downward to squeeze the spring 2 under the guidance of the guide plate. The slide plate and the spring 2 cooperate to further buffer the explosion energy. At the same time, as the slide plate moves, the guide grooves on the guide plate are gradually exposed, and the explosion energy enters each guide groove and then enters the counter-pressure chamber. The explosion energy on both sides is offset and reduced in the counter-pressure chamber, and the buffer pad can buffer the explosion energy in the counter-pressure chamber and reduce the impact force on the counter-pressure chamber. The baffle can cooperate with the torsion spring and the limit plate to prevent the explosion energy from returning to the shell. The above arrangement enables the universal explosion-proof solenoid valve device to better guide and buffer the explosion energy and extend the service life of the explosion-proof shell.

[0028] A general flameproof solenoid valve device, such as Figure 1-Figure 4 As shown, it comprises a shell 1, inside of which a buffer component 4 for buffering explosion shock waves is arranged.

The above structure enables the universal explosion-proof solenoid valve device to better guide and buffer the explosion energy and extend the service life of the explosion-proof housing.
