Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a temperature control ball valve. Background Technology

[0002] A ball valve is a type of valve that opens and closes by rotating a ball controlled by a valve stem. A thermostat ball valve can be used with a temperature sensor to sense the water temperature and then control the hot water flow rate based on the water temperature to achieve the purpose of temperature regulation.

[0003] Existing technologies often have the following drawbacks: during the long-term use of temperature control ball valves, impurities and particles in the medium can enter the valve body with the fluid and accumulate inside, easily causing valve blockage and affecting the normal operation of the valve. Disassembling the ball valve for cleaning is often quite complicated, resulting in low efficiency in cleaning the ball valve.

[0004] Therefore, this utility model provides a temperature control ball valve. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing temperature control ball valves, where impurities and particles in the medium can enter the valve body and accumulate inside during long-term use, easily causing valve blockage and affecting normal operation. Furthermore, disassembling the ball valve for cleaning is often complex and inefficient. Therefore, this invention proposes a temperature control ball valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature control ball valve, comprising a valve body and a ball core, wherein a valve stem is fixedly connected to the inner wall of the ball core, a temperature sensor is installed inside the valve stem, a drain pipe is connected to the surface of the valve body, a threaded sealing rod is threadedly inserted into the inner wall of the drain pipe, and a blocking plate is fixedly connected to one end of the threaded sealing rod near the ball core, the blocking plate being slidably connected to the inner wall of the drain pipe.

[0007] The above-mentioned components achieve the following effects: the drain pipe facilitates the treatment and discharge of impurities and dirt inside the valve body, and the plug plate and threaded sealing rod ensure a sealing effect on the end face of the drain pipe.

[0008] Preferably, a sealing ring is detachably installed on the inner wall of the sewage pipe, and the sealing ring is slidably connected to the surface of the blockage plate.

[0010] Preferably, the sealing ring has two positioning holes on its side, and the inner wall of the drain pipe is slidably connected to two positioning rods, both of which are slidably connected to the surface of the positioning holes.

[0011] The aforementioned components achieve the following effects: by using the positioning rod and positioning hole, they can provide positioning when replacing the sealing ring, and at the same time, they can restrict the position of the sealing ring.

[0012] Preferably, a control plate is fixedly connected to the end of each of the two positioning rods away from the sealing ring, and a first spring is sleeved on the surface of each of the two positioning rods. The two ends of the first spring are fixedly connected to the control plate and the drain pipe, respectively.

[0013] The effect achieved by the above components is that when the sealing ring needs to be replaced, the positioning rod can be moved and its position restricted by the control board, thereby facilitating the disassembly and installation of the sealing ring. The position of the positioning rod can be restricted by the first spring and the control board.

[0014] Preferably, the valve body has two fixing plates fixedly connected to its surface. Both fixing plates are installed on the side of the control plate away from the drain pipe, and the inner walls of both fixing plates are slidably connected to limit rods.

[0015] The effect achieved by the above components is that the limiting rod, which is slidably connected to the inner wall of the fixed plate, can move, thereby limiting the position of the control plate.

[0016] Preferably, a pull plate is fixedly connected to the end of the limiting rod away from the control plate.

[0017] The effect achieved by the above components is that the movement of the limit rod can be easily controlled by the pull plate.

[0018] Preferably, a second spring is fitted on the surface of the limiting rod, and the two ends of the second spring are fixedly connected to the pull plate and the fixing plate, respectively.

[0019] The above components achieve the following effects: the pull plate facilitates the installation of the second spring, and the pull plate and the second spring ensure a stable connection between the limit rod and the fixed plate.

[0020] In summary:

[0021] In this invention, the drain pipe allows for the removal of impurities from inside the ball valve when necessary. By releasing the threaded sealing rod from the drain pipe, the interior of the valve body can be cleaned and impurities discharged through it, thus facilitating the cleaning of the ball valve and improving its efficiency.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a temperature control ball valve, including a valve body 1 and a ball core 2. A valve stem 3 is fixedly connected to the inner wall of the ball core 2, and a temperature sensor 4 is installed inside the valve stem 3. A drain pipe 5 is connected to the surface of the valve body 1. A threaded sealing rod 6 is threadedly inserted into the inner wall of the drain pipe 5. A blocking plate 7 is fixedly connected to one end of the threaded sealing rod 6 near the ball core 2, and the blocking plate 7 is slidably connected to the inner wall of the drain pipe 5. The drain pipe 5 facilitates the treatment and discharge of impurities and dirt inside the valve body 1, and the blocking plate 7 and the threaded sealing rod 6 achieve a sealing effect on the end face of the drain pipe 5.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] Reference Figures 1-5As shown in this embodiment: a sealing ring 8 is detachably installed on the inner wall of the drain pipe 5, and the sealing ring 8 is slidably connected to the surface of the plug plate 7. The sealing ring 8 improves the sealing effect of the drain pipe 5, thereby minimizing leakage. Two positioning holes 9 are provided on the side of the sealing ring 8, and two positioning rods 10 are slidably connected to the inner wall of the drain pipe 5. Both positioning rods 10 are slidably connected to the surface of the positioning holes 9. The positioning rods 10 and positioning holes 9 provide a positioning effect when replacing the sealing ring 8, and also limit its position. A control plate 11 is fixedly connected to the end of each positioning rod 10 away from the sealing ring 8. A first spring 12 is fitted onto the surface of each positioning rod 10, and both ends of the first spring 12 are fixedly connected to the control plate 11 and the drain pipe 5, respectively. When the sealing ring 8 needs to be replaced, the positioning rod 10 can be moved and its position restricted by the control board 11, so as to facilitate the disassembly and installation of the sealing ring 8. The position of the positioning rod 10 can be restricted by the first spring 12 and the control board 11.

[0031] Two fixing plates 13 are fixedly connected to the surface of the valve body 1. Both fixing plates 13 are installed on the side of the control plate 11 away from the drain pipe 5. Limiting rods 14 are slidably connected to the inner walls of both fixing plates 13. The limiting rods 14 slidably connected to the inner walls of the fixing plates 13 can move, thereby limiting the position of the control plate 11. A pull plate 15 is fixedly connected to the end of the limiting rod 14 away from the control plate 11. The pull plate 15 facilitates the movement of the limiting rod 14. A second spring 16 is sleeved on the surface of the limiting rod 14. The two ends of the second spring 16 are fixedly connected to the pull plate 15 and the fixing plate 13, respectively. The pull plate 15 facilitates the installation of the second spring 16, and the pull plate 15 and the second spring 16 ensure a stable connection between the limiting rod 14 and the fixing plate 13.

[0032] Working principle: When using the temperature control ball valve, first connect its two ends to the inlet pipe and the outlet pipe. The valve stem 3 controls the rotation of the ball core 2, thereby opening and closing the temperature control ball valve. During use, the temperature sensor 4 inside the valve stem 3 can monitor the fluid temperature inside the valve body 1 through copper heat conduction. When it is necessary to clean the impurities inside the valve body 1, rotate the threaded sealing rod 6 to move the plug plate 7 away from the drain pipe 5. Then, the impurities and dirt inside the valve body 1 are discharged through the drain pipe 5. When it is necessary to replace the sealing ring 8, pull the pull plate 15 to move the limit rod 14 to slide on the inner wall of the fixed plate 13, so that the pull plate 15 moves away from the fixed plate 13. Then move the control plate 11 closer to the fixed plate 13, so that the positioning rod 10 moves away from the sealing ring 8. Release the pull plate 15. Under the action of the second spring 16, the limit rod 14 moves closer to the control plate 11, restricting the position of the control plate 11 and the positioning rod 10. Then the sealing ring 8 can be replaced. Pull the pull plate 15 to move the limit rod 14 away from the control plate 11. At this time, under the action of the first spring 12, the positioning rod 10 approaches the positioning hole 9 on the sealing ring 8, limiting the sealing ring 8, realizing the positioning and replacement of the sealing ring 8. By using the drain pipe 5, when it is necessary to discharge impurities inside the ball valve, the drain pipe 5 can be opened by releasing the threaded sealing rod 6, and the inside of the valve body 1 can be cleaned and impurities discharged through the drain pipe 5. This facilitates the cleaning of the ball valve and improves the efficiency of cleaning the ball valve.
