Description

Technical Field

[0001] This utility model relates to the field of pulse valve technology, specifically a submerged pulse valve. Background Technology

[0002] Submerged pulse valves are the core component of baghouse dust collector cleaning systems, and their performance directly affects the operating resistance, dust removal efficiency, and filter bag lifespan of the dust collector. Their working principle involves controlling the pressure change in the diaphragm chamber of the pulse valve by opening and closing an electromagnetic pilot valve. This causes the diaphragm to open rapidly, instantly injecting compressed air stored in the air tank into the filter bag, forming a powerful pulse airflow that removes dust adhering to the outer surface of the filter bag.

[0003] During the automatic operation of a baghouse dust collector, the cleaning action occurs intermittently and at a high frequency. This means that the electromagnetic coil inside the pulse valve needs to withstand short-duration, high-frequency energizing pulses. This makes it difficult for the heat generated by the coil to be effectively dissipated to the surrounding environment. With each pulse, the coil generates heat due to the Joule effect. In the continuous, high-frequency cleaning cycle, the rate of heat accumulation in the coil far exceeds its dissipation rate, causing the coil temperature to rise continuously. High temperatures accelerate the aging and embrittlement of the coil's enameled wire insulation, eventually leading to insulation breakdown, inter-turn short circuits, and ultimately, complete coil burnout, causing the pulse valve to malfunction. Utility Model Content

[0004] The purpose of this utility model is to provide a submerged pulse valve, which has a heat dissipation pipe in the housing. The gas discharged through the pilot exhaust port enters the heat dissipation pipe, which carries away the heat inside the housing and avoids the coil from overheating.

[0005] To address the problems of existing technologies, this utility model provides a submerged pulse valve, characterized in that it includes a pulse valve body, which comprises a lower main valve body and an upper pilot valve body. The main valve body has an air chamber, and the pilot valve body has a channel communicating with the air chamber in the main valve body. The pilot valve body also has a pilot exhaust port communicating with the channel. A housing is provided above the pilot valve body, and a heat dissipation assembly capable of carrying away heat from the inside of the housing is provided outside the pilot valve body. The heat dissipation assembly includes two heat dissipation pipes respectively disposed at the upper and lower ends inside the housing, and the heat dissipation pipes are spirally coiled inside the housing.

[0006] Preferably, a coil is fixed inside the housing, and an iron core assembly that moves up and down is provided at the center of the coil. A junction box is provided outside the housing, and the junction box is electrically connected to the coil through a wire.

[0007] Preferably, the upper and lower ends of the housing are provided with exhaust holes, and one end of the heat dissipation pipe is connected to the exhaust holes.

[0008] Preferably, the heat dissipation assembly includes a connector that can be inserted into a pilot exhaust port. One end of the connector is connected to a main pipe, a tee pipe is connected to the main pipe, and two branch pipes are connected to the tee pipe, which are respectively connected to two heat dissipation pipes.

[0009] Preferably, the heat dissipation assembly further includes a stop block mounted on the connector, and the stop block has a magnet embedded in it that attracts the end face of the pilot exhaust port.

[0010] Preferably, the heat dissipation assembly further includes a third sealing ring sleeved on the outside of the connector, and the third sealing ring can be embedded in the pilot exhaust port.

[0011] Preferably, the pilot valve body is further provided with a secondary diaphragm at the junction of the pilot exhaust port and the channel, and the secondary diaphragm is also provided with a second throttling hole. The top of the pilot exhaust port is provided with a second reset spring for resetting the secondary diaphragm, and the bottom of the iron core assembly is connected to the secondary diaphragm.

A main diaphragm is provided at the junction of the air outlet and the air inlet, and a first throttling hole is provided on the main diaphragm. A first return spring is also provided on the top of the main diaphragm for resetting the main diaphragm.

[0013] The advantages of this utility model compared to the prior art are: This application constructs a highly efficient heat dissipation channel by arranging spirally wound heat dissipation tubes at both the upper and lower ends inside the housing. One end of each heat dissipation tube is connected to a pre-designed exhaust port on the housing, while the other end is fixedly connected to a distribution pipe via a flange structure, achieving airflow diversion. The end of the distribution pipe furthest from the heat dissipation tube is connected to a branch interface of a tee pipe. The main interface of the tee pipe is connected to the main pipeline via a threaded connection. The integrated insertion interface at the end of the main pipeline is inserted into the pilot exhaust port with an interference fit, ensuring the sealing and stability of the gas transmission process. When the valve body is opened, the discharged high-pressure gas enters the main pipeline through the pilot exhaust port, is distributed to the two distribution pipes by the diversion effect of the tee pipe, and then guided into the spirally wound heat dissipation tubes. As the gas flows within the spiral channel of the heat dissipation tubes, it exchanges heat with the internal environment of the housing, quickly removing the heat generated by the housing and internal components. This effectively controls the internal temperature of the housing within a safe threshold range, avoiding damage such as decreased coil insulation performance and winding burnout caused by high temperatures, ensuring long-term stable operation of the equipment.

[0019] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-4 As shown, this utility model provides a submerged pulse valve, including a pulse valve body 1. The pulse valve body 1 includes a lower main valve body 11 and an upper pilot valve body 12. The main valve body 11 has an air chamber. The pilot valve body 12 has a channel 121 that communicates with the air chamber in the main valve body 11. The pilot valve body 12 also has a pilot exhaust port 123 that communicates with the channel 121. A secondary diaphragm 122 is also provided inside the pilot valve body 12 at the junction of the pilot exhaust port 123 and the channel 121. A second throttling orifice 1221 is also provided on the secondary diaphragm 122. A second return spring 124 for resetting the secondary diaphragm 122 is provided at the top of the pilot exhaust port 123. The bottom of the iron core assembly 127 is connected to the secondary diaphragm 122. A coil 126 is fixed inside the housing 125, and an iron core assembly 127 that moves up and down is provided at the center of the coil 126. A junction box 128 is provided outside the housing 125, and the junction box 128 is electrically connected to the coil 126 through wires.

[0021] When coil 126 is not energized, no electromagnetic attraction is generated, and the second return spring 124 is in its naturally extended state. Its elastic pressure pushes the secondary diaphragm 122 to tightly adhere to the junction of channel 121 and pilot exhaust port 123, achieving a seal of channel 121. The valve is in the closed state, and gas cannot be ejected. After an external control signal is triggered, junction box 128 supplies power to coil 126 through wires. After coil 126 is energized, it generates a strong electromagnetic attraction, attracting the iron core assembly 127 to move upward axially. The iron core assembly 127 drives the connected secondary diaphragm 122 to move upward synchronously, causing the secondary diaphragm 122 to detach from the sealing surface of channel 121, and channel 121 to connect with pilot exhaust port 123. High-pressure gas in the main valve body 11's gas chamber flows into pilot exhaust port 123 through channel 121, causing the gas chamber pressure to drop rapidly, breaking the internal pressure balance of the main valve body 11, driving the main valve body 11 to open, and realizing pulsed injection of compressed gas. When the control signal stops, the coil 126 is de-energized, the electromagnetic attraction disappears, and the elastic restoring force of the second reset spring 124 pushes the iron core assembly 127 and the secondary diaphragm 122 to reset. The secondary diaphragm 122 reseals the channel 121, the pilot exhaust port 123 stops exhausting, and the valve returns to the closed state.

[0022] An air outlet 112 is provided at the center of the bottom of the main valve body 11, and a first sealing ring 115 is provided inside the air outlet 112. An air inlet 111 is provided at the bottom of the main valve body 11 concentric with the air outlet 112, and the air inlet 111 is connected to the air outlet 112. A second sealing ring 116 is sleeved on the outside of the air inlet 111. A main diaphragm 113 is provided at the junction of the air outlet 112 and the air inlet 111, and a first throttling hole 1131 is provided on the main diaphragm 113. A first return spring 114 for resetting the main diaphragm 113 is also provided on the top of the main diaphragm 113.

[0023] Upon triggering by an external control signal, junction box 128 supplies power to coil 126. Coil 126 generates electromagnetic attraction, drawing the iron core assembly 127 upwards, causing the secondary diaphragm 122 to detach from the sealing surface of channel 121. Channel 121 then connects with pilot exhaust port 123. High-pressure gas above the main diaphragm 113 is rapidly discharged through channel 121 and pilot exhaust port 123, causing a sudden drop in pressure above the main diaphragm 113. Meanwhile, high-pressure gas continuously enters through the air inlet 111 below the main diaphragm 113, creating a pressure difference. Under the action of this pressure difference, the main diaphragm 113 overcomes the elastic force of the first return spring 114 and deforms downwards, fully connecting the air inlet 111 with the air outlet 112. High-pressure gas is then pulsed and ejected through the air outlet 112.

[0024] A housing 125 is located above the pilot valve body 12. A heat dissipation assembly 2 is also provided on the outside of the pilot valve body 12 to remove heat from inside the housing 125. As a dedicated heat dissipation unit for the pilot valve body 12, the heat dissipation assembly 2 uses gas flow and heat exchange principles to quickly dissipate the heat generated by the coil 126 inside the housing 125 during operation, preventing high temperature accumulation that could damage the coil 126 and ensuring the long-term stable operation of the electromagnetic control unit. It is a core component for high-temperature protection of the pulse valve. The heat dissipation assembly 2 includes two heat dissipation pipes 28, respectively located at the upper and lower ends inside the housing 125, with the heat dissipation pipes 28 spirally wound inside the housing 125. The spiral winding structure of the heat dissipation pipes 28 maximizes the contact area with the air inside the housing 125. The heat generated by the housing 125 and the coil 126 is carried away by the internally circulating gas, achieving efficient heat dissipation. Exhaust holes 1251 are provided at the upper and lower ends of the housing 125, and one end of the heat dissipation pipe 28 is connected to the exhaust hole 1251. The heat dissipation assembly 2 includes a connector 24 that can be inserted into the pilot exhaust port 123. The connector 24 is inserted into the pilot exhaust port 123 with an interference fit to ensure the sealing and stability of the gas transmission process. One end of the connector 24 is connected to a main pipe 25, and a tee pipe 26 is connected to the main pipe 25. Two branch pipes 27 are connected to the tee pipe 26, and the two branch pipes 27 are respectively connected to two heat dissipation pipes 28. The heat dissipation assembly 2 also includes a stop block 21 installed on the connector 24, and a magnet 22 is embedded in the stop block 21 to attract the end face of the pilot exhaust port 123. The magnet 22 uses magnetic attraction to quickly position and tightly fit the connector 24 and the pilot exhaust port 123, enhancing the stability of the connection and preventing loosening of the connection due to gas flow or equipment vibration. The heat dissipation assembly 2 also includes a third sealing ring 23 sleeved on the outside of the plug interface 24, and the third sealing ring 23 can be embedded in the pilot exhaust port 123. When the plug interface 24 is inserted into the pilot exhaust port 123, the third sealing ring 23 is embedded in the gap between the two to achieve a sealing effect and prevent gas from leaking at the connection.

[0025] After an external control signal is triggered, junction box 128 supplies power to coil 126. Coil 126 generates electromagnetic attraction to lift iron core assembly 127, causing secondary diaphragm 122 to detach from the sealing surface of channel 121. Channel 121 then connects to pilot exhaust port 123. Gas flows into connector 24 through channel 121 and pilot exhaust port 123, enters T-connector 26 through main pipe 25, and is then split by T-connector 26 before being directed by two branch pipes 27 to the spiral heat dissipation pipes 28 at the upper and lower ends of housing 125. As the gas flows within heat dissipation pipes 28, it undergoes thorough heat exchange with the air inside housing 125 and coil 126, quickly carrying away the heat generated by coil 126. Finally, the gas is discharged through exhaust port 1251 of housing 125, preventing excessive heat buildup inside housing 125.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
