Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve boxes, in particular to an explosion-proof electromagnetic valve box. Background Art

[0002] The solenoid valve box is a device that converts electrical signals into mechanical displacement or mechanical force. It is composed of an electromagnet, a valve body, a seal and other parts. The opening or closing of the valve is controlled by the magnetic force generated by the electromagnet after being acted upon by the electrical signal, thereby controlling the flow direction and flow rate of the medium.

[0003] Solenoid valve boxes are widely used in many industries, such as the power equipment industry and the mechanical equipment industry. In power equipment, they are used to monitor circuits, control power transmission, and keep equipment safe and stable. In mechanical equipment, they are used to regulate air pressure, valves, and piston movements to achieve precise operation of mechanical systems.

[0004] There is a closed cavity inside the solenoid valve box, with through holes opened at different positions. Each hole is connected to a different pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. When the electromagnet coil on one side is energized, the valve body is attracted to that side, thereby opening or closing the corresponding oil drain hole. The oil inlet hole is normally open, and the hydraulic oil pushes the piston and piston rod through the oil pressure, thereby driving the mechanical device to work.

[0005] However, in the prior art, most solenoid valve boxes are sealed structures, and most of the boxes contain various control circuits. The circuits will generate a certain temperature when working, and when a short circuit occurs in the circuit, a fire is likely to occur, which will cause the temperature in the control box to rise sharply, and the pressure will increase accordingly, and there will also be a risk of explosion, which is inconvenient to use. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an explosion-proof solenoid valve box to solve the technical problem that most of the solenoid valve boxes in the prior art are sealed structures, and most of the boxes contain various control circuits. The circuits will also generate a certain temperature when working, and when a short circuit occurs in the circuit, a fire is likely to occur, which will cause the temperature in the control box to rise sharply, and the pressure will increase accordingly, which will also cause the risk of explosion.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof solenoid valve box, comprising a box body, a cavity is opened in the box body, heat dissipation ports are opened on both sides of the box body, a first block and a second block used in conjunction with the heat dissipation ports are arranged in the cavity, a fixed frame is arranged on the back of the box body, the fixed frame is located at the back of the box body, a gas storage block is arranged in the fixed frame, the gas storage block is filled with gas that expands due to heat, a piston block is arranged in the gas storage block, a movable rod is arranged on the top of the piston block, a sensor is arranged on the top of the fixed frame, a first induction block and a second induction block used in conjunction with the sensor are arranged in the fixed frame, a first spring is arranged between the first induction block and the second induction block, a material guide pipe is arranged in a symmetrical structure in the cavity, a nozzle is arranged on the inner side of the material guide pipe, and a material storage box used in conjunction with the material guide pipe and the nozzle is arranged on the top of the box body.

[0008] By adopting the above technical scheme, under normal circumstances, the first blocking block and the second blocking block are located above the heat dissipation port, and the heat dissipation port can be used to dissipate heat and cool down the inside of the box. Under abnormal circumstances, the temperature in the box rises, and the heat dissipation port is blocked by the first blocking block and the second blocking block, so that the cavity reaches a closed state, and the gas in the gas storage block expands after being heated, thereby squeezing the piston block. When the piston block is squeezed by the gas, it moves upward, driving the movable rod to move upward until the movable rod squeezes the second sensing block until the second sensing block contacts the first sensing block. When the first sensing block contacts the second sensing block, the sensor starts working. When the sensor starts working, the storage box, the guide pipe and the nozzle are driven to cooperate with each other, so that the fire extinguishing dry powder in the storage box can be filled into the cavity, so as to achieve the effect of rapid fire extinguishing, thereby improving the safety of the explosion-proof solenoid valve box.

[0009] The utility model is further configured that electronic components are integrated in the box, and the electronic components are an integration of a control unit of the solenoid valve.

[0010] By adopting the above technical solution and integrating electronic components in the control unit of the solenoid valve, the entire explosion-proof solenoid valve box can be put into normal use.

[0011] The utility model is further configured such that a connecting block is fixedly connected to the bottom of the first blocking block, a telescopic rod is symmetrically arranged in the cavity, the output end of the telescopic rod is fixedly connected to the telescopic connecting block, a second spring is fixedly connected between the first blocking block and the second blocking block, a protrusion used to cooperate with the second blocking block is symmetrically arranged in the cavity, and the protrusion is located above the heat dissipation port.

[0012] By adopting the above technical scheme, the connection block and the telescopic rod cooperate with each other, so that the first blocking block and the second blocking block can move up and down relative to the line in the cavity, so as to achieve the effect of blocking the heat dissipation port according to actual usage. The second blocking block can be squeezed by the convex block. When the first blocking block and the second blocking block move downward, the second blocking block is no longer subject to the squeezing force of the convex block. The heat dissipation port in the box can be blocked by the performance of the second spring itself, so as to facilitate the mutual cooperation between the auxiliary guide pipe and the nozzle to fill the fire extinguishing dry powder into the cavity.

[0013] The utility model is further configured that a plurality of groups of inlet pipes are arranged at the bottom of the box body, and a box door is rotatably connected to the front side of the box body.

[0014] By adopting the above technical solution, the provided wire inlet pipe can assist in wiring the electronic components in the box. Secondly, the box door rotatably connected to the box can achieve a protective effect on the electronic components in the box.

[0015] The utility model is further configured that a connecting pipe is arranged on the top of the material guiding pipe, the connecting pipe is connected to the material storage box, and a controller used in conjunction with the sensor is arranged in the material storage box.

[0016] By adopting the above technical solution, the connecting pipe can guide the fire extinguishing dry powder in the storage box into the guide pipe, and then spray the fire extinguishing dry powder into the cavity through the nozzle. Secondly, through the controller used in conjunction with the sensor, when the sensor works, the controller is triggered so that the inner wall of the box can be filled with fire extinguishing dry powder in time.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model can achieve the effect of heat dissipation and cooling inside the box through the heat dissipation port. When abnormal, the temperature inside the box rises, and the heat dissipation port is blocked by the first blocking block and the second blocking block, so that the cavity reaches a closed state, so that the gas in the gas storage block expands after being heated, thereby squeezing the piston block. When the piston block is squeezed by the gas, it will move upward, driving the movable rod to move upward until the movable rod squeezes the second sensing block until the second sensing block contacts the first sensing block. When the first sensing block contacts the second sensing block, the sensor starts to work. When the sensor starts to work, the storage box, the guide pipe and the nozzle are driven to cooperate with each other, so that the fire extinguishing dry powder in the storage box can be filled into the cavity, so as to achieve the effect of rapid fire extinguishing, and improve the safety of the explosion-proof solenoid valve box;

[0019] 2. The utility model cooperates with the connecting block and the telescopic rod to enable the first blocking block and the second blocking block to move up and down relative to the line in the cavity, so as to achieve the effect of blocking the heat dissipation port according to actual usage conditions. The second blocking block can be squeezed by the convex block. When the first blocking block and the second blocking block move downward, the second blocking block is no longer subject to the squeezing force of the convex block. The performance of the second spring itself can block the heat dissipation port in the box, so as to facilitate the mutual cooperation between the auxiliary guide pipe and the nozzle to fill the fire extinguishing dry powder into the cavity.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0031] Under normal circumstances, the first blocking block 13 and the second blocking block 22 are located above the heat dissipation port 4, and the heat dissipation port 4 can be used to dissipate heat and cool down the inside of the box body 1. Under abnormal circumstances, the temperature in the box body 1 rises, and the heat dissipation port 4 is blocked by the first blocking block 13 and the second blocking block 22, so that the cavity 9 reaches a closed state, and the gas in the gas storage block 16 expands after being heated, thereby squeezing the piston block 24. When the piston block 24 is squeezed by the gas, it will move upward, driving the movable rod 10 to move upward until the movable rod 10 squeezes the second sensing block 20 until the second sensing block 20 contacts the first sensing block 18.

When the first blocking block 13 and the second blocking block 22 move downward, the second blocking block 22 is no longer subjected to the squeezing force of the protrusion 23. Through the performance of the second spring 21 itself, the heat dissipation port 4 in the box body 1 can be blocked, so as to facilitate the mutual cooperation between the auxiliary guide pipe 11 and the nozzle 12 to fill the fire extinguishing dry powder into the cavity 9.

[0033] In this embodiment, the inlet pipe 5 provided can assist in wiring the electronic components 6 in the box body 1. Secondly, the box door 2 rotatably connected to the box body 1 can achieve a protective effect on the electronic components 6 in the box body 1. Finally, the connecting pipe 14 provided can guide the fire extinguishing dry powder in the storage box 3 into the guide pipe 11, and then the fire extinguishing dry powder is sprayed into the cavity 9 through the nozzle 12. Secondly, through the controller used in conjunction with the sensor 17, when the sensor 17 is working, the controller is triggered so that the inner wall of the box body 1 is filled with the fire extinguishing dry powder in time.
