Description

Technical Field

[0001] The utility model relates to the technical field of fluid control equipment, in particular to a titanium alloy three-way valve box. Background Technique

[0002] Due to its excellent corrosion resistance, high strength, light weight and other characteristics, the titanium alloy three-way valve box is widely used in various industrial fields. The titanium alloy three-way valve box can not only realize the distribution and merging of fluids, but also be used for controlling the flow rate, direction switching function, isolation function and pressure regulation of liquids and gases.

[0003] Most of the existing titanium alloy three-way valve boxes drive the valve ball inside the valve body to rotate with a valve rod to realize the switching of the liquid flow direction and the control of the flow rate. However, due to the frequent use of the valve rod, the gap between the valve rod and the valve body will gradually increase, resulting in leakage at the valve rod. The leakage will cause continuous loss of fluid and waste of resources. At the same time, the working medium of the titanium alloy three-way valve box may contain some impurities. When the fluid flows through the inlet flange of the three-way valve, due to the change in the fluid flow rate, these impurities will deposit at the flange to form a blockage. The blockage will cause hindrance to the fluid when passing through the flange connection, affecting the normal circulation of the fluid. Summary of the Utility Model

[0018] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0019] 1. The present utility model cancels the traditional direct driving of the valve ball by the valve rod. Instead, the rotating shaft drives the second permanent magnet to rotate. The second permanent magnet drives the first permanent magnet to rotate through the magnetic field, and the first permanent magnet drives the valve ball to rotate through the fixing block, avoiding the problem that the gap between the valve rod and the valve body increases due to frequent use of the valve rod, improving the service life of the equipment to a certain extent, and reducing the operation cost.

[0020] 2. Through the cooperation of the turbine blade and the filter plate, the present utility model enables the water flow to possibly form a turbulent flow when passing through the filter plate. The turbulent effect generated by the turbulent flow can further enhance the effect of removing particulate matter on the filter plate. Moreover, the disturbance of the turbulent flow to the surface of the filter plate can enhance the impact force and shear force, thereby further removing the particulate matter attached to the filter plate. The shear force generated when the water flow passes through the filter screen can also weaken the adhesion force between the particulate matter and the surface of the filter plate, and further make the particulate matter more likely to fall off the filter plate, reducing the blockage of the filter plate to a certain extent, ensuring the normal circulation of the fluid, and stabilizing the pressure in the pipeline, laying a foundation for the stable operation of the system.

[0030] As Figure 4 shown, a valve ball 5 is movably embedded on the inner surface of the valve body 4. The top of the valve ball 5 is fixedly connected with a fixing block 6. A plurality of first permanent magnets 7 are fixedly connected to the inner surface of the fixing block 6. The plurality of first permanent magnets 7 and the plurality of second permanent magnets 8 do not contact each other, and the valve ball 5 can change the flow direction of the fluid in the valve body 4.

[0031] As Figure 4 shown, a maintenance slot 19 is formed on the outer surface of the valve body 4. A plurality of second permanent magnets 8 are movably embedded on the inner surface of the maintenance slot 19, and the maintenance slot 19 can provide a good working environment for the second permanent magnets 8.

[0032] As Figure 2 、 Figure 3 and Figure 4 shown, the bottom of the stepper motor 12 is fixedly connected with a support plate 11. The bottom of the support plate 11 is fixedly connected with a plurality of support rods 10. The plurality of support rods 10 are fixedly connected to the top of the valve body 4, and the support rods 10 can support the support plate 10.

[0033] As Figure 2 and Figure 3 shown, a plurality of connecting pipes 2 are fixedly connected to the outer surface of the valve body 4. Flange plates 3 are fixedly connected to one side of each of the plurality of connecting pipes 2 away from the valve body 4. The flange plates 3 are connected to the pipeline through bolts.

[0034] As Figures 1-3 shown, a filtering mechanism is arranged on the inner surface of one of the flange plates 3, and the filtering mechanism can filter the fluid.

[0035] As Figures 1-3 shown, the filtering mechanism includes a filter plate 17. The filter plate 17 is movably embedded on the inner surface of one of the flange plates 3. A plurality of turbine blades 18 are fixedly connected to the outer surface of the filter plate 17, and the turbine blades 18 can convert the power of part of the fluid into the power for the rotation of the turbine blades 18.

[0036] As Figure 4 shown, a maintenance mechanism is arranged on the inner surface of the maintenance slot 19, and the maintenance mechanism is convenient for maintaining the second permanent magnets 8.

[0037] As Figure 3 and Figure 4As shown in the figure, the maintenance mechanism includes two maintenance plates 13. The two maintenance plates 13 are movably embedded in the inner surface of the maintenance groove 19. Bolts 14 are threadedly connected to the outer surfaces of the two maintenance plates 13. Two fastening rods 15 are fixedly connected to the outer surface of one of the maintenance plates 13, and two fastening grooves 16 are formed in the outer surface of the other maintenance plate 13.

[0038] Working principle: This device is a titanium alloy three-way valve box. The support rod 10 and the support plate 11 can support the stepping motor 12. When in use, the stepping motor 12 is started. The stepping motor 12 drives the rotating shaft 9 to rotate through the output shaft. The rotating shaft 9 drives the permanent magnet two 8 to rotate on the inner surface of the maintenance groove 19, causing the permanent magnet two 8 to generate a rotating magnetic field and penetrate the valve body 4. Here, the valve body 4 is made of titanium metal, and titanium metal has little influence on the transmission of magnetic force. Therefore, when the permanent magnet two 8 rotates, it will affect the permanent magnet one 7 and cause the permanent magnet one 7 to rotate.

[0039] When the permanent magnet one 7 rotates following the permanent magnet two 8, it will drive the valve ball 5 to rotate through the fixing block 6. Thus, the flow control and direction switching of the liquid of the three-way valve can be realized. Therefore, the permanent magnet two 8 plays a very important role in the whole device. When it is necessary to inspect the permanent magnet two 8, remove the two bolts 14, then lift the two maintenance plates 13, and then separate the two maintenance plates 13 to both sides, pulling the fastening rods 15 out of the fastening grooves 16, so that the permanent magnet two 8 can be maintained. When the liquid enters the connecting pipe 2 through the flange 3, it will first pass through the filter plate 17, and the turbine blades 18 on the filter plate 17 will rotate under the impact of the water flow. Then, the turbine blades 18 will drive the filter plate 17 to rotate inside one of the flanges 3. The box body 1 can protect the three-way valve.
