Description

Technical Field

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

[0002] Solenoid ball valve is a valve driven by electromagnetic force, mainly used to control the on and off of fluids (such as liquids and gases). Its basic structure includes valve body, ball (usually made of stainless steel or other corrosion-resistant materials), electromagnetic coil, spring and sealing materials. The internal space of a submarine is limited and closed, and there are various flammable gases (such as hydrogen and oil gas released by batteries) and potential fire sources. When using solenoid valves on submarines, sparks accidentally generated during operation will enter the interior through the gaps at the joints and cause explosions, thereby damaging the submarine, affecting the service life of the submarine, and endangering the safety of the operator.

[0003] Therefore, it is necessary to design an explosion-proof electromagnetic ball valve that can isolate the connection between the spherical valve body and the connector to prevent sparks from entering the interior through the gap in the connection during use and causing an explosion, thereby protecting the safety of the submarine and the operator and extending the service life of the submarine. Utility Model Content

[0004] In order to overcome the disadvantage that when using a solenoid valve on a submarine, sparks accidentally generated during operation may enter the interior through the gap at the connection and cause an explosion, thereby causing damage to the submarine, affecting the service life of the submarine, and endangering the safety of the operator, the utility model provides an explosion-proof solenoid ball valve that can isolate the connection between the spherical valve body and the connecting piece to prevent sparks from entering the interior through the gap at the connection during use and causing an explosion, thereby protecting the safety of the submarine and the operator and extending the service life of the submarine.

[0005] The technical solution of the utility model is: an explosion-proof electromagnetic ball valve, including a spherical valve body, a connecting piece, a motor, a controller, a fixing screw and an isolation mechanism, the upper middle side of the spherical valve body is detachably connected with the connecting piece by a fixing screw, the connecting piece is connected with the motor, a ball valve is arranged on the output shaft of the motor, a controller is connected to the left upper part of the motor, and an isolation mechanism for explosion-proof is arranged on the spherical valve body.

[0006] As a preferred technical solution of the utility model, flanges are provided on the left and right parts of the spherical valve body.

[0007] As a preferred technical solution of the utility model, the spherical valve body is made of stainless steel and has good corrosion resistance and mechanical properties.

[0008] As a preferred technical solution of the utility model, the isolation mechanism includes an isolation cover, a connecting plate, an adjusting screw and a limit ring. Two front and rear isolation covers are placed on the spherical valve body. The left and right sides of the upper part of the isolation cover are connected with connecting plates. The connecting plates on the rear side are rotatably connected with adjusting screws. The adjusting screws are connected to the connecting plates adjacent to the front side through threads. The front part of the adjusting screws is connected to the limit ring through threads, and the limit rings are in contact with the connecting plates adjacent to the front side.

[0009] As a preferred technical solution of the utility model, it also includes a monitoring mechanism, which includes a temperature sensor and an alarm light. The left part of the isolation cover is connected to the temperature sensor, and the right part of the isolation cover is connected to the alarm light. The temperature sensor is electrically connected to the alarm light on the same side.

[0010] As a preferred technical solution of the utility model, a cooling fan is also included, and the upper part of the isolation cover is connected to the cooling fan.

[0011] Compared with the prior art, the utility model has the following advantages: 1. The utility model fixes the isolation cover by manually rotating the adjusting screw rod so that the isolation covers contact each other, and then twists the limit ring so that the limit ring contacts the connecting plate, thereby isolating the connection between the spherical valve body and the connecting piece, preventing sparks from entering the interior through the gap at the connection during use and causing an explosion, thereby protecting the safety of the submarine and the operator and extending the service life of the submarine.

[0012] 2. During the use of the utility model, the cooling fan is started to dissipate the heat of the isolation cover through the cooling fan. When the temperature sensor senses that the temperature of the isolation cover is high, the alarm light comes on, so that the isolation cover can be cooled while the temperature is monitored to provide prompts, thereby accelerating the heat dissipation effect and preventing high temperature from affecting the normal operation of the ball valve.

[0019] An explosion-proof electromagnetic ball valve, such as Figure 1-Figure 3 As shown, it includes a spherical valve body 1, a connecting piece 2, a motor 3, a controller 4, a fixing screw 5 and an isolation mechanism 6. The left and right parts of the spherical valve body 1 are provided with flanges for easy docking.

[0020] like Figure 1 and Figure 3 As shown, the isolation mechanism 6 includes an isolation cover 61, a connecting plate 62, an adjusting screw 63 and a limiting ring 64. Two front and rear isolation covers 61 are placed on the spherical valve body 1. The left and right sides of the upper part of the isolation cover 61 are connected with connecting plates 62. The rear connecting plate 62 is rotatably connected with an adjusting screw 63. The adjusting screw 63 is connected to the connecting plate 62 adjacent to the front side through a thread. The front part of the adjusting screw 63 is connected to the limiting ring 64 through a thread, and the limiting ring 64 is in contact with the connecting plate 62 adjacent to the front side.

[0021] like Figure 1 and Figure 4 As shown, a monitoring mechanism 7 is also included, which includes a temperature sensor 71, an alarm light 72 and a cooling fan 73. The left part of the isolation cover 61 is connected to the temperature sensor 71, and the right part of the isolation cover 61 is connected to the alarm light 72.

The isolation cover 61 is placed on the spherical valve body 1, and then the adjusting screw rod 63 is contacted with the front connecting plate 62. The isolation cover 61 is fixed by turning the adjusting screw rod 63 by hand so that the two isolation covers 61 are in contact with each other, and then the limiting ring 64 is contacted with the adjusting screw rod 63, and then the limiting ring 64 is twisted so that the limiting ring 64 and the connecting plate 62 are in contact. Contact, then start the motor 3 through the controller 4, and drive the ball valve to rotate through the motor 3, and then use the device, so that the connection between the spherical valve body 1 and the connecting piece 2 can be isolated, to prevent sparks from entering the interior through the gap at the connection during use and causing an explosion, thereby protecting the safety of the submarine and the operator and extending the service life of the submarine. During use, start the cooling fan 73, and use the cooling fan 73 to dissipate the heat of the isolation cover 61. When the temperature sensor 71 senses that the temperature of the isolation cover 61 is high, the alarm light 72 lights up, so that the isolation cover 61 can be cooled while the temperature is monitored to prompt, thereby accelerating the heat dissipation effect and avoiding high temperature from affecting the normal operation of the ball valve.
