Description

Technical Field

[0001] This utility model relates to the field of pulse valve technology, specifically a right-angle pulse valve with a flange. Background Technology

[0002] Pulse valves are the core actuators in pulse jet baghouse dust collectors and pulse jet cleaning systems. Their performance directly determines the dust removal efficiency, operational stability, and service life of the dust collection equipment. In industrial dust removal and environmental protection, pulse valves need to quickly open and close to spray high-pressure airflow onto the filter bags, achieving efficient dust removal from the filter bag surface. Currently, pulse valves on the market are mainly divided into straight-through and right-angle types. Among them, right-angle pulse valves are widely used in compact dust collection equipment due to their reasonable airflow direction and small installation space requirement.

[0003] While the currently mainstream right-angle pulse valves are widely used in compact dust removal systems due to their advantages such as reasonable airflow deflection design and small installation space, they have significant technical defects in their core drive structure and heat dissipation design. Specifically, the coil of the pulse valve, as the core component for generating electromagnetic force, requires a continuous pulse current to achieve the reciprocating motion of the iron core assembly; however, existing coils mostly adopt a sealed encapsulation structure and are not equipped with dedicated heat dissipation channels or heat dissipation elements, resulting in the Joule heat generated when current passes through not being dissipated in time. This insufficient heat dissipation problem can trigger a series of chain reactions: First, the continuous rise in coil temperature will accelerate the aging of its insulation layer, and may even cause local burnout, directly shortening the coil's service life and increasing valve maintenance and replacement costs; Second, excessively high temperatures will change the electromagnetic characteristics of the coil, leading to unstable electromagnetic force output, which in turn will reduce the accuracy of the core assembly and piston's movement, resulting in problems such as delayed valve opening and closing and poor sealing, affecting the stability of high-pressure airflow injection, and ultimately reducing the filter bag cleaning efficiency; Third, under high-frequency blowing conditions, the coil heating frequency and heat accumulation rate will significantly increase, further exacerbating the insufficient heat dissipation problem, and may even cause a short circuit in the coil, leading to the overall failure of the pulse valve, causing the dust removal system to shut down, and affecting the continuity of industrial production. Utility Model Content

[0004] The purpose of this utility model is to provide a right-angle pulse valve with a flange, which increases the heat conduction effect by setting heat-conducting fins and heat-conducting pipes inside the shell, and draws in external air into the heat-conducting pipes when the valve is opened to carry away the heat, thus solving the problem of excessive heat inside the shell.

[0005] To address the problems of existing technologies, this utility model provides a flanged right-angle pulse valve, comprising a pulse valve body. The pulse valve body includes a main valve body disposed at the lower part and a pilot valve body disposed at the upper part. A housing is disposed on the top of the pilot valve body, and a coil is disposed inside the housing. A heat dissipation assembly for dissipating heat from the inside of the housing is disposed on the pulse valve body. The heat dissipation assembly includes several heat-conducting fins installed inside the housing. A heat-conducting tube is spirally wound on the heat-conducting fins, and one end of the heat-conducting tube extends to the outside of the housing.

[0006] Preferably, the bottom of the main valve body is provided with an air outlet, and the bottom of the air outlet is also provided with a first flange.

[0007] Preferably, the outlet has a venturi channel for gas passage, and a pipe joint is connected to the outside of the outlet, with one end of the pipe joint extending into the venturi channel. The other end of the heat-conducting pipe is connected to a connecting pipe, and one end of the connecting pipe is connected to a plug, which is fitted onto the pipe joint.

[0008] Preferably, the pipe joint is divided into an inlet section, a contraction section, a throat, and a diffuser section. The inlet section is cylindrical, the contraction section is conical with a cone angle of 21°±2°, the throat is a straight pipe section with a diameter of 1 / 3 to 1 / 4 of the diameter of the inlet section, and the diffuser section is a conical pipe with a cone angle of 8° to 15°. The pipe joint is inserted into the throat.

[0009] Preferably, the main valve body is provided with an air inlet on the outside, the air inlet is perpendicular to the air outlet, one end of the air inlet is connected to a second flange, and the air outlet is connected to the air inlet.

[0010] Preferably, a diaphragm is provided at the junction of the air outlet and the air inlet, and a return spring is provided on the top of the return spring for resetting the diaphragm, and a drainage hole is provided on the diaphragm.

[0011] Preferably, the pilot valve body has an exhaust port located near the main valve body, and the exhaust port extends into the interior of the pilot valve body. The main valve body also has a piston that can move up and down. When the piston blocks the exhaust port, the main valve body is in a closed state. When the piston moves upward to open the exhaust port, the main valve body is in an open state.

[0012] Preferably, the pilot valve body is further provided with an iron core assembly that can move up and down in the coil, and the bottom end of the iron core assembly is connected to the piston. The outer shell is provided with a junction box, and the junction box is electrically connected to the coil through a wire.

[0013] The advantages of this utility model compared to the prior art are: This application integrates several heat-conducting fins inside the outer casing, utilizing the high thermal conductivity of the fins to increase the heat dissipation contact area and significantly improve the heat transfer efficiency inside the casing. Simultaneously, heat pipes are arranged in a spiral coil within the casing cavity, extending the heat transfer path and increasing the contact area between the heat pipes and the casing, heat-conducting fins, and the internal environment, further enhancing thermal conductivity. This forms a composite heat-conducting structure of "heat-conducting fins + spiral heat pipes," laying the foundation for efficient heat dissipation. In the internal flow channel of the air outlet, this application designs and incorporates a Venturi channel, with the pipe connector inserted into the throat region of the Venturi channel. When gas flows through the Venturi channel, according to the Venturi effect, the airflow velocity at the throat section increases sharply along the flow direction, resulting in the formation of the lowest pressure zone within the system in this area. At this point, the pressure difference between the external environment and the throat region generates a driving force, causing air from the surrounding environment to continuously flow into the heat pipe from the inlet. As the airflow passes through the inside of the heat pipe, it fully exchanges heat with the pipe wall, efficiently carrying away the heat conducted by the heat pipe, and finally being discharged from the outlet with the main airflow. Through this pressure-driven forced convection cooling mechanism, rapid and efficient heat dissipation of the outer shell and its internal components is achieved, effectively ensuring the operational stability of the equipment under high-temperature conditions.

[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 flanged right-angle pulse valve, including a pulse valve body 1. The pulse valve body 1 includes a main valve body 11 disposed at the lower part and a pilot valve body 12 disposed at the upper part. A housing 122 is disposed on the top of the pilot valve body 12. A coil 124 is disposed inside the housing 122. A heat dissipation component 2 for dissipating heat inside the housing 122 is disposed on the pulse valve body 1. The heat dissipation component 2 includes a plurality of heat-conducting fins 21 installed inside the housing 122. A heat-conducting pipe 22 is spirally wound on the heat-conducting fins 21, and one end of the heat-conducting pipe 22 extends to the outside of the housing 122.

[0021] The heat-conducting fins 21 are arranged around the coil 124, which increases the heat dissipation area and quickly absorbs the heat generated by the coil 124, thus dispersing and transferring the concentrated heat. The heat-conducting pipe 22 is spirally wound around the heat-conducting fins 21 (increasing the contact area with the fins and improving the heat conduction efficiency), which can quickly conduct the heat collected by the heat-conducting fins 21 to the external environment.

[0022] The main valve body 11 has an outlet 111 at its bottom, and a first flange 1111 is also provided at the bottom of the outlet 111. A Venturi channel 112 for gas passage is opened inside the outlet 111. A pipe connector 1121 is connected to the outside of the outlet 111, with one end of the pipe connector 1121 extending into the Venturi channel 112. The other end of the heat-conducting pipe 22 is connected to a connecting pipe 23, and one end of the connecting pipe 23 is connected to a plug 24, which is fitted onto the pipe connector 1121. The pipe connector 1121 consists of an inlet section, a contraction section, a throat, and a diffuser section. The inlet section is cylindrical, the contraction section is conical with a cone angle of 21°±2°, the throat is a straight pipe section with a diameter of 1 / 3-1 / 4 of the inlet section diameter, and the diffuser section is a conical pipe with a cone angle of 8°-15°. The pipe connector 1121 is inserted into the throat.

[0023] When the airflow passes through the Venturi channel 112, it first accelerates in the contraction section (increased velocity, decreased pressure), reaching its highest velocity and lowest pressure at the throat. Then, it decelerates and increases pressure in the diffusion section, ultimately forming a more concentrated and powerful pulsed airflow, improving the cleaning efficiency for filter bags and other targets. According to the Venturi effect, the airflow velocity at the throat section increases sharply along the flow direction, resulting in the lowest pressure zone within the system. At this time, the pressure difference between the external environment and the throat region generates a driving force, causing air from the surrounding environment to continuously flow into the heat pipe 22 from the inlet. As the airflow passes through the heat pipe 22, it fully exchanges heat with the pipe wall, efficiently carrying away the heat conducted by the heat pipe 22, and finally exits from the outlet 111 with the main airflow, thus reducing the temperature inside the outer shell 122.

[0024] An exhaust port 126 is provided on the pilot valve body 12 near the main valve body 11, and the exhaust port 126 extends into the pilot valve body 12. The main valve body 11 also has a piston 121 that can move up and down. When the piston 121 blocks the exhaust port 126, the main valve body 11 is in a closed state; when the piston 121 moves upward to open the exhaust port 126, the main valve body 11 is in an open state. The pilot valve body 12 also has an iron core assembly 125 that can move up and down in a coil 124, and the bottom end of the iron core assembly 125 is connected to the piston 121. A junction box 123 is provided outside the outer casing 122, and the junction box 123 is electrically connected to the coil 124 via wires. An air inlet 113 is provided outside the main valve body 11, perpendicular to the air outlet 111. One end of the air inlet 113 is connected to a second flange 114, and the air outlet 111 communicates with the air inlet 113. A diaphragm 115 is provided at the junction of the air outlet 111 and the air inlet 113, and a return spring 116 is provided on the top of the return spring 116 for resetting the diaphragm 115, and a drainage hole is provided on the diaphragm 115.

[0025] When junction box 123 receives no drive signal, coil 124 is de-energized and has no electromagnetic force. Iron core assembly 125 drives piston 121 downwards, blocking exhaust port 126. Compressed air from intake port 113 partially enters the upper chamber through the drainage hole of diaphragm 115, balancing the pressure in the upper chamber with that at intake port 113. Under the combined action of the return spring 116 and the upper chamber pressure, diaphragm 115 is pressed against the junction of intake port 113 and outlet port 111, blocking airflow. The main valve closes, and outlet port 111 has no output. When junction box 123 receives an input signal, coil 124 is energized, generating electromagnetic force that attracts iron core assembly 125 upwards, driving piston 121 to open exhaust port 126. Air in the upper chamber is rapidly discharged through exhaust port 126, causing a sudden pressure drop. Below diaphragm 115, the air source remains at high pressure. The pressure difference overcomes the elasticity of the return spring 116, pushing diaphragm 115 upwards and opening the passage between inlet 113 and outlet 111. Compressed air rushes from inlet 113 into outlet 111, mixes with the auxiliary airflow from pipe joint 1121 via venturi channel 112, forming a strong pulsed airflow, which is then output through first flange 1111.

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.
