The sealing forms of the regulating ball valve are soft seal and metal hard seal. It is often widely used in petroleum, chemical, papermaking and metallurgy industries. The regulating ball valve core has a strong shearing effect when rotating.

[0003] The existing V-type ball valve is generally provided with an extended pipe mouth at the bottom of the ball valve for installing a thermometer, but the thermometer and the pipe mouth are generally installed by threads. Although this installation method is simple and quick, it is prone to thread slippage during long-term use, which makes it impossible to install the thermometer and requires replacement of the entire ball valve, thereby increasing the cost. At the same time, water rust is prone to appear on the threads, which makes it difficult to disassemble the thermometer in the later stage. Therefore, a high-precision temperature measurement and adjustment V-type ball valve is needed to solve the above problems. Utility Model Content

Although this installation method is simple and quick, it is prone to thread slippage during long-term use, which makes it impossible to install the temperature sensor and requires the replacement of the entire ball valve, thereby increasing the cost. At the same time, water rust is prone to appear on the threads, which makes it difficult to disassemble the temperature sensor in the later stage and inconvenient to disassemble.

[0005] The utility model provides the following technical solutions: a high-precision temperature measurement and adjustment V-type ball valve, comprising a ball valve, a rotating rod is rotatably provided at the top of the ball valve, a knob is fixedly connected to the top of the rotating rod, a fixed tube is fixedly connected to the bottom end of the ball valve, an adjustment mechanism for flow regulation is provided between the top of the ball valve and the bottom end of the knob, an outer plate is fixedly connected to the outer end of the fixed tube, a plurality of slots are provided at the bottom end of the outer plate, rectangular slots are spaced apart at the side ends of each of the slots, a limiting mechanism is provided in each of the rectangular slots, a mounting mechanism is provided at the bottom end of the fixed tube, and a temperature detector is provided in the middle of the mounting mechanism.

[0006] As a preferred embodiment of the above technical solution, the limiting mechanism includes a spring, which is fixedly connected to the inner side end of the rectangular groove, the side end of the spring is fixedly connected to a rectangular plate, the top end of the rectangular plate is fixedly connected to a pull plate, and the side end of the rectangular plate is fixedly connected to an insert block.

[0007] As a preference of the above technical solution, a limiting groove is opened at the top end of the rectangular groove, and the pulling plate is located in the limiting groove.

[0008] As a preference of the above technical solution, the bottom end of the insertion block is arc-shaped, and the insertion block is inserted into the insertion slot.

[0009] As a preference of the above technical solution, the installation mechanism includes an installation head. An annular groove is opened at the top end of the installation head.

[0011] As a preference of the above technical solution, the adjusting mechanism includes a bracket. The bracket is fixedly connected to the top end of the ball valve. A ring plate is fixedly connected to the top end of the bracket. A plurality of convex blocks are fixedly connected to the top end of the ring plate. An elastic flap is fixedly connected to the bottom end of the knob, and the elastic flap is located between two adjacent convex blocks.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the settings of the installation mechanism and the limiting mechanism in the present utility model, the annular groove of the installation head is inserted into the bottom end of the fixed pipe. At this time, the bottom end of the fixed pipe presses against the sealing ring, making the sealing and waterproof performance between the installation head and the fixed pipe better. The measuring device is inserted into the fixed pipe and the ball valve and contacts the flow rate inside the ball valve. At this time, the insertion plate is inserted into the insertion slot. When the insertion plate contacts the insertion block, since the bottom end of the insertion block is arc-shaped, it is convenient to press the insertion block to move towards the direction inside the rectangular groove. At this time, the rectangular plate presses the spring to contract. After the insertion plate is completely inserted into the insertion slot and fits with the insertion slot, the spring can push the rectangular plate to rebound. At this time, the insertion block is inserted into the notch opening, thereby limiting and fixing the position of the insertion plate in the insertion slot. At this time, it is convenient to complete the installation and fixation of the installation head and the measuring device. Subsequently, by pulling the pulling plate, the rectangular plate and the insertion block are driven to move, so that the insertion block disengages from the notch opening. At this time, pulling the installation head downward can facilitate the disassembly of the measuring device and the installation head. Therefore, this device is convenient for quickly installing and disassembling the installation head and the temperature detector. When the measuring device is damaged, only the measuring device needs to be disassembled, and there is no need to replace the entire ball valve, which reduces the cost. At the same time, it also solves the problem that the temperature detector and the pipe orifice are generally installed by threads. Although this installation method is simple and fast, it is prone to thread slipping during long-term use, resulting in the inability to install the temperature detector and the need to replace the entire ball valve, thus increasing the cost. At the same time, water rust is also likely to appear at the thread, making it difficult to disassemble the temperature detector in the later stage and causing inconvenience in disassembly.

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Such as Figures 1-4As shown in the figure, the present utility model provides a technical solution: a high-precision temperature-measuring and regulating V-ball valve, including a ball valve 1, where the ball valve 1 is a V-ball valve 1 in the prior art. A rotating rod 101 is rotatably provided at the top end of the ball valve 1, and a knob 102 is fixedly connected to the top end of the rotating rod 101. By rotating the knob 102, the rotating rod 101 and the internal valve body can be driven to rotate, thereby controlling the conveying and closing of the flow rate inside the ball valve 1. A fixed pipe 3 is fixedly connected to the bottom end of the ball valve 1. An adjusting mechanism for flow rate adjustment is provided between the top end of the ball valve 1 and the bottom end of the knob 102. The setting of the adjusting mechanism can facilitate the adjustment of the flow rate inside the ball valve 1. An outer plate 301 is fixedly connected to the outer end of the fixed pipe 3. A plurality of slots 302 are opened at the bottom end of the outer plate 301. A rectangular groove 303 is spaced apart from the side end of each slot 302. A limiting mechanism is provided in each rectangular groove 303. An installation mechanism is provided at the bottom end of the fixed pipe 3. A temperature detector 6 is provided in the middle of the installation mechanism. The temperature detector 6 is a device in the prior art installed inside the ball valve 1 to measure the temperature of the fluid. Through the combined setting of the limiting mechanism and the installation mechanism, the problem that the temperature detector 6 and the pipe orifice are generally installed by threads is solved. Although this installation method is simple and fast, it is prone to thread slipping during long-term use, resulting in the inability to install the temperature detector 6 and the need to replace the entire ball valve 1, thus increasing the cost. At the same time, water rust is also likely to appear at the thread, making it difficult to disassemble the temperature detector 6 in the later stage and inconvenient to disassemble.

[0021] As an implementation manner in this embodiment, as Figure 2 and Figure 4 shown, the installation mechanism includes an installation head 5. An annular groove 501 is opened at the top end of the installation head 5. A sealing ring 502 is installed at the bottom end inside the annular groove 501. A plurality of insertion plates 503 are fixedly connected to the top end of the installation head 5. A notch 504 is opened at the side end of each insertion plate 503. The temperature detector 6 is fixedly connected to the middle of the installation head 5. During implementation, by inserting the annular groove 501 of the installation head 5 to the bottom end of the fixed pipe 3, at this time, the bottom end of the fixed pipe 3 presses against the sealing ring 502, making the sealing and waterproof performance between the installation head 5 and the fixed pipe 3 better. The measuring device is inserted into the fixed pipe 3 and the ball valve 1 and contacts the flow rate inside the ball valve 1. At this time, the insertion plates 503 are inserted into the slots 302. The limiting mechanism can facilitate the limitation of the notch 504, thereby realizing the limiting and fixing of the insertion plates 503 and the installation head 5, and thus facilitating the installation and disassembly of the measuring device. When the measuring device is damaged, only the measuring device needs to be disassembled, and there is no need to replace the entire ball valve 1, reducing the cost.

[0022] As an implementation manner in this embodiment, as Figure 4As shown, the limiting mechanism includes a spring 4, which is fixedly connected to the inner side end of the rectangular groove 303, and the side end of the spring 4 is fixedly connected to a rectangular plate 401, and the top of the rectangular plate 401 is fixedly connected to a pull plate 402, and the top of the rectangular groove 303 is provided with a limiting groove 304, and the pull plate 402 is located in the limiting groove 304, and the side end of the rectangular plate 401 is fixedly connected to an insert block 403, and the bottom end of the insert block 403 is arc-shaped, and the insert block 403 is inserted into the slot 302. In practice, the insert plate 503 is inserted into the slot 302. When the insert plate 503 contacts the insert block 403, since the bottom end of the insert block 403 is arc-shaped, it is easy to press the insert block 4 03 moves toward the direction of the rectangular groove 303. At this time, the rectangular plate 401 presses the spring 4 to shrink. When the plug plate 503 is completely inserted into the slot 302 and adapts to the slot 302, the spring 4 can rebound against the rectangular plate 401. At this time, the plug block 403 is inserted into the slot 504, thereby limiting and fixing the position of the plug plate 503 in the slot 302. At this time, it is convenient to complete the installation and fixation of the installation head 5 and the measuring device. Subsequently, by pulling the pull plate 402, the rectangular plate 401 and the plug block 403 are driven to move, so that the plug block 403 is separated from the slot 504. At this time, pulling the installation head 5 downward can facilitate the disassembly of the measuring device and the installation head 5.

[0023] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, the adjustment mechanism includes a bracket 2, the bracket 2 is fixedly connected to the top of the ball valve 1, the top of the bracket 2 is fixedly connected to a ring plate 201, the top of the ring plate 201 is fixedly connected to a plurality of protrusions 202, the bottom end of the knob 102 is fixedly connected to an elastic paddle 203, and the elastic paddle 203 is located between two adjacent protrusions 202. In implementation, as Figure 3 As shown, the elastic paddle 203 is located at the outermost edge of the plurality of protrusions 202. At this time, the ball valve 1 is in a closed state. When the knob 102 is turned, the rotating rod 101 and the V-shaped valve body in the ball valve 1 are driven to rotate. The elastic paddle 203 can produce a slight deformation between the plurality of protrusions 202 to achieve the shifting. Each time the side end of a protrusion 202 is shifted, the valve body will open a little, and the fluid will flow out. When the elastic paddle 203 is shifted to the other edge of the plurality of protrusions, the valve body is completely opened, and the fluid flow rate is the fastest. Therefore, the setting of the elastic paddle 203 and the plurality of protrusions 202 can be used by the assistant to adjust the size and speed of the fluid flow rate. Since the plurality of protrusions 202 are set as the size standard of the fluid flow rate, each time the side end of a protrusion 202 is shifted, the valve body will open a little, and the flow rate will increase a little, thereby improving the accuracy of the fluid regulation of the ball valve 1.

[0024] Working principle: By inserting the annular groove 501 of the mounting head 5 to the bottom end of the fixed pipe 3, at this time, the bottom end of the fixed pipe 3 presses against the sealing ring 502, making the sealing and waterproof performance between the mounting head 5 and the fixed pipe 3 better. The measuring device is inserted into the fixed pipe 3 and the ball valve 1 to contact the flow rate inside the ball valve 1. At this time, the insertion plate 503 is inserted into the insertion slot 302. When the insertion plate 503 contacts the insertion block 403, since the bottom end of the insertion block 403 is arc-shaped, it is convenient to press the insertion block 403 to move in the direction of the rectangular groove 303. At this time, the rectangular plate 401 presses the spring 4 to contract. When the insertion plate 503 is completely inserted into the insertion slot 302 and fits with the insertion slot 302, the spring 4 can push the rectangular plate 401 to rebound. At this time, the insertion block 403 is inserted into the notch 504, thereby limiting and fixing the position of the insertion plate 503 in the insertion slot 302. At this time, it is convenient to complete the installation and fixation of the mounting head 5 and the measuring device. Subsequently, by pulling the pull plate 402, the rectangular plate 401 and the insertion block 403 are driven to move, so that the insertion block 403 disengages from the notch 504. At this time, pulling the mounting head 5 downward can facilitate the disassembly of the measuring device and the mounting head 5. Therefore, this device is convenient for quickly installing and disassembling the mounting head 5 and the temperature measuring device 6. When the measuring device is damaged, only the measuring device needs to be disassembled, without replacing the entire ball valve 1, which reduces the cost. At the same time, it also solves the problem that the temperature measuring device 6 and the pipe orifice are generally installed by threads. Although this installation method is simple and fast, it is prone to thread slipping during long-term use, resulting in the inability to install the temperature measuring device 6 and the need to replace the entire ball valve 1, thus increasing the cost. At the same time, water rust is also likely to appear at the thread, making it difficult to disassemble the temperature measuring device 6 in the later stage and causing inconvenience in disassembly.
