Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and specifically relates to a multi-channel valve. Background Art

[0002] A multi-channel valve is a complex industrial device mainly used to control the flow of various media such as fluids, gases, steam, dry air, etc. It has multiple inlets or outlets and can realize the switching and control of multiple channels within one valve body. The multi-way valve is mainly used to simplify the pipeline and valve system by replacing multiple two-way valves and automation equipment with one multi-way valve, simplifies system verification, and reduces the housing profile, making it easier to install and operate safely in a limited space;

[0003] The multi-way valve minimizes dead ends and optimizes drainage. Furthermore, the working environment of multi-channel valves is diverse, and the working environment of some multi-channel valves is relatively harsh. For example, in areas such as factories with high temperatures, the internal sealing structure of multi-channel valves is complex, including pneumatic seals and static seals. These seals all require the use of sealing materials. When the temperature rises, the physical and chemical properties of the sealing materials will change. Some multi-channel valves may lack additional cooling and heat dissipation measures when operating in a high-temperature environment;

[0004] To solve the above problems, a multi-channel valve is proposed in this application. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model proposes a multi-channel valve to overcome the above technical problems existing in the prior related art.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A multi-channel valve includes a valve body. A heat dissipation circular frame is fixedly connected to the outer surface of the valve body. A positioning disc is welded to the inner surface of the heat dissipation circular frame. One side of the positioning disc close to the valve body is fixedly connected with a heat pipe. The outer surface of the heat pipe is lapped with the outer surface of the valve body. A plurality of heat dissipation fins are installed on the side of the positioning disc away from the valve body. A water tank is fixedly connected to the outer surface of the heat dissipation circular frame. A heat dissipation hole is opened at the top of the water tank. A filter screen is movably connected to the inner surface of the water tank, and the filter screen is located in the heat dissipation hole.

[0008] Both sides of the water tank are provided with glass windows, and scale lines are opened on the outer surfaces of the glass windows. By setting the glass windows and scale lines, operators can quickly observe and know the remaining volume of the liquid inside the water tank through the glass windows and scale lines, which is convenient for operators to replenish water to the water tank in a timely manner.

[0009] A load-bearing rod is fixedly connected to the top of the filter net, and a positioning rod is installed at the top of the load-bearing rod. The positioning rod is movably inserted into the inner cavity of the water tank. By providing the load-bearing rod and the positioning rod, when the positioning rod is forced to move upward, the filter net can be driven upward by the load-bearing rod, facilitating the operator to quickly remove the filter net for cleaning and maintenance.

[0010] A support plate is lapped on one side of the water tank away from the valve body, and a positioning round lamp is installed on the outer surface of the support plate. By providing the support plate and the positioning round lamp, the positioning round lamp can intermittently flash after being started, facilitating the operator to quickly find the specific working position of the valve body at night.

[0011] A limiting concave block is fixedly connected to the outer surface of the water tank, and the inner surface of the limiting concave block is movably connected to the outer surface of the support plate. By providing the limiting concave block, after the support plate is forced to move upward and completely disengages from the inner surface of the limiting concave block, the fixed state between the support plate and the water tank is quickly released, facilitating the operator to quickly remove and replace the support plate and the positioning round lamp as a whole.

[0012] An adjustment box is fixedly connected to the bottom of the valve body, a micro air pump is fixedly connected to the bottom of the valve body, an air inlet pipe is installed at the input end of the micro air pump, an air delivery pipe is installed at the output end of the micro air pump, the air delivery pipe is fixedly inserted into the inner cavity of the adjustment box, an exhaust pipe is fixedly inserted into the inner cavity of the adjustment box, and an electromagnetic valve is arranged in the inner cavity of the exhaust pipe. By providing the adjustment box, the micro air pump, the air inlet pipe, the air delivery pipe and the exhaust pipe, when the micro air pump is started, air can be continuously delivered to the adjustment box through the air inlet pipe and the air delivery pipe. As the volume of the gas inside the adjustment box gradually increases, the total weight of the valve body and the adjustment box as a whole can be gradually increased, facilitating the flexible adjustment of the working weight of the valve body and maximizing the effect of improving the stability of the valve body during operation.

[0013] In summary, the technical effects and advantages of the present utility model are as follows:

[0014] 1. For this multi-channel valve, the positioning disc, heat pipe and heat sink on the surface of the valve body can guide and transfer the heat generated during the operation of the valve body outward. Since the surface of the heat sink is in contact with the water tank and there is a certain amount of water inside the water tank, the water source inside the water tank absorbs heat and gradually vaporizes. Through multiple heat dissipation methods, it is convenient to maximize the heat dissipation efficiency of the valve body during operation and maximize the service life of the valve body in a high-temperature environment.

[0015] 2. For this multi-channel valve, starting the micro air pump can gradually deliver air into the adjustment box through the air inlet pipe and the air delivery pipe. As the volume of the gas inside the adjustment box gradually increases, the total weight of the adjustment box and the valve body gradually increases, facilitating the flexible adjustment of the working weight of the valve body according to complex environments and further improving the stability of the valve body during operation.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figure 1-2 , a multi-channel valve, including a valve body 1. A heat dissipation circular frame 2 is fixedly connected to the outer surface of the valve body 1. The vertical cross-sectional area of the heat dissipation circular frame 2 is smaller than the vertical cross-sectional area of the valve body 1. The heat dissipation circular frame 2 is installed at the central part of the side surface of the valve body 1; A positioning disc 3 is welded to the inner surface of the heat dissipation circular frame 2. One side of the positioning disc 3 close to the valve body 1 is fixedly connected with a heat pipe 4. The outer surface of the heat pipe 4 is lapped with the outer surface of the valve body 1. A plurality of heat sinks 5 are installed on the side of the positioning disc 3 away from the valve body 1. The positioning disc 3, heat pipe 4 and heat sink 5 on the inner surface of the heat dissipation circular frame 2 can guide and release the heat generated when the valve body 1 works to the outside.

[0024] Refer to Figure 1-2, a water tank 6 is fixedly connected to the outer surface of the heat dissipation circular frame 2. A water source is placed on the inner surface of the water tank 6. One side of the water tank 6 close to the valve body 1 is fixedly connected to the side of the heat sink 5 away from the valve body 1. A heat dissipation hole 7 is opened at the top of the water tank 6. The water source inside the water tank 6 can slowly absorb the heat released by the heat sink 5 and gradually vaporize, so that the heat conversion efficiency of the heat sink 5 is further improved, which is convenient for improving the heat dissipation efficiency of the valve body 1 and helps the valve body 1 maintain an effective working efficiency in a harsh working environment; a filter screen 8 is movably connected to the inner surface of the water tank 6. The filter screen 8 is located in the heat dissipation hole 7. The water vapor generated by vaporization inside the water tank 6 can be discharged outwards through the heat dissipation hole 7, and the filter screen 8 on the inner surface of the water tank 6 can block foreign impurities from polluting the water source inside the water tank 6.

[0025] Refer to Figure 1 , glass windows 9 are arranged on both sides of the water tank 6. Operators can observe the flow of the water source inside the water tank 6 through the transparent glass windows 9. At the same time, operators can also judge whether the water source inside the water tank 6 is polluted by impurities; scale lines 10 are opened on the outer surface of the glass windows 9. The scale lines 10 on the surface of the glass windows 9 can assist operators in quickly judging the remaining volume of the water source inside the water tank 6, which is convenient for operators to quickly judge the replenishment time and replenishment volume of the water source.

[0026] Refer to Figure 1 and Figure 3 , a load-bearing rod 11 is fixedly connected to the top of the filter screen 8. The height of the load-bearing rod 11 is less than the height of the water tank 6. A positioning rod 12 is installed at the top of the load-bearing rod 11; the positioning rod 12 is movably inserted into the inner cavity of the water tank 6. The length of the positioning rod 12 is less than the length of the water tank 6. When the positioning rod 12 is inserted into the top of the water tank 6, the positioning rod 12 can provide a supporting force for the filter screen 8 through the load-bearing rod 11; when the operator moves the positioning rod 12 upwards, the filter screen 8 can be quickly moved through the load-bearing rod 11. When the filter screen 8 is completely separated from the inner surface of the water tank 6 under force, the operator can quickly clean and replace the filter screen 8.

[0027] Refer to Figure 1, on one side of the water tank 6 away from the valve body 1, there is a supporting plate 13 lapped. The outer surface of the supporting plate 13 is movably connected to the outer surface of the water tank 6. A positioning round lamp 14 is installed on the outer surface of the supporting plate 13. A button battery is installed inside the positioning round lamp 14, and after the positioning round lamp 14 is activated, it can intermittently flash at night, facilitating the operator to quickly locate the working position of the valve body 1 at night. The outer surface of the water tank 6 is fixedly connected with limiting concave blocks 15. The number of the limiting concave blocks 15 is two, and the two limiting concave blocks 15 are symmetrically distributed with the supporting plate 13 as the center; the inner surface of the limiting concave block 15 is movably connected to the outer surface of the supporting plate 13. When the supporting plate 13 is in contact with the two limiting concave blocks 15 at the same time, the working position of the supporting plate 13 is restricted by the two symmetrically distributed limiting concave blocks 15. When the supporting plate 13 is forced to move upward and completely disengages from the inner surface of the limiting concave block 15, the operator can quickly remove the supporting plate 13 and perform maintenance and replacement on the positioning round lamp 14.

[0028] Refer to Figure 4 , the bottom of the valve body 1 is fixedly connected with an adjustment box 16. The horizontal cross-sectional area of the adjustment box 16 is smaller than the horizontal cross-sectional area of the valve body 1, and the adjustment box 16 is installed at the central part of the bottom of the valve body 1; the bottom of the valve body 1 is fixedly connected with a micro air pump 17. The micro air pump 17 uses an external power supply and the specific model of the micro air pump 17 is A. An air inlet pipe 18 is installed at the input end of the micro air pump 17, and an air delivery pipe 19 is installed at the output end of the micro air pump 17. The materials and radii of the air inlet pipe 18 and the air delivery pipe 19 are the same, and both the air inlet pipe 18 and the air delivery pipe 19 are made of rubber; the air delivery pipe 19 is fixedly inserted into the inner cavity of the adjustment box 16. Starting the micro air pump 17 can continuously deliver air into the adjustment box 16 through the air inlet pipe 18 and the air delivery pipe 19. As the gas volume inside the adjustment box 16 gradually increases, the weight of the adjustment box 16 gradually increases, facilitating the flexible adjustment of the total weight of the adjustment box 16 and the valve body 1 and maximizing the stability of the adjustment box 16 during operation; an exhaust pipe 20 is fixedly inserted into the inner cavity of the adjustment box 16, and a solenoid valve is arranged in the inner cavity of the exhaust pipe 20. After the solenoid valve is activated, the excess gas in the adjustment box 16 can be quickly discharged.

[0029] Working principle: First, the working fluid inside the heat pipe 4 can quickly conduct heat, enabling the heat to be quickly conducted from the valve body 1 to the heat pipe 4 and the heat sink 5. The heat sink 5 uses the principle of heat transfer to transfer the heat from the heat source to the air by increasing the surface area to achieve the purpose of heat dissipation. Since the surface of the heat sink 5 is in contact with the water tank 6 and there is a certain amount of water source inside the water tank 6, the water source inside the water tank 6 gradually vaporizes after absorbing heat, and the vaporization of the water source can further take away the heat released by the heat sink 5. Through multiple heat dissipation methods, it is convenient to maximize the heat dissipation efficiency of the valve body 1 during operation and maximize the service life and working efficiency of the valve body 1 in a high-temperature environment.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
