Description

Technical Field

[0001] The utility model relates to the technical field of ball valve anti-freezing and cracking auxiliary devices, in particular to an anti-freezing and cracking ball valve. Background Art

[0002] Valves are very common in people's daily lives, yet they also seem to be unknown. Because southern China has not been subjected to sub-zero weather for a long time, valves often lack appropriate insulation measures. Eventually, when a cold wave arrives and the temperature drops below zero, water has an anti-expansion characteristic between 0℃-4℃. At 4℃, the density is the largest (1.00g / cm3). When it is cooled to 0℃ and formed into ice, the density decreases (0.92g / cm3). In other words, water shrinks when heated (at 4℃) and expands when cooled (at 0℃). When water freezes, it produces an anti-expansion phenomenon, which leads to a large number of valves being frozen and cracked.

[0003] The existing ball valve is not equipped with an antifreeze auxiliary device, which causes the ball valve to be easily damaged in a low temperature environment, reducing the service life of the ball valve. Therefore, it is particularly important to design an anti-freeze cracking ball valve to solve the above technical problems. Utility Model Content

[0004] The utility model aims to solve the problem that the existing ball valve is not provided with an antifreeze auxiliary device, which causes the ball valve to be easily damaged in a low temperature environment and reduces the service life of the ball valve, and proposes an antifreeze cracking ball valve.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an anti-freeze cracking ball valve, comprising a valve body, the valve body is made of corrosion-resistant material, the left end of the valve body is a water inlet, the right end of the valve body is a water outlet, a valve core is rotatably connected to the valve body, a working block is installed on the top of the valve body, the top of the valve core is fixedly connected to a rotating shaft, sealing rings are fixedly connected to the valve body on both sides of the valve core, a heating ring is embedded in the valve body, a heating resistor is installed in the heating ring, a control box is fixedly connected to the left side of the working block, a power supply is embedded in the control box, and the control box and the heating resistor are connected by wires.

[0006] Preferably, a motor is installed on the top of the working block, a rotor is rotatably connected to the motor, and the rotating shaft is connected to the rotor.

[0007] Preferably, the heating ring has a circular ring structure.

[0008] Preferably, a thermal insulation layer is fixedly connected to the outer wall of the valve body, and the thermal insulation layer is made of corrosion-resistant material.

[0009] Preferably, a temperature monitor is fixedly connected to the right side of the working block, a temperature measuring tube is installed at the bottom of the temperature monitor, and the temperature measuring tube is communicated with the interior of the valve body.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] 1. In the utility model, during use, a working block structure is installed above the valve body, and a temperature monitor is installed on the right side of the working block and a control box structure is installed on the left side. First, the temperature monitor cooperates with the temperature measuring tube to monitor the water temperature inside the valve body in real time. After detecting an abnormal temperature, the control box cooperates with the power supply to supply power to the heating resistor in the heating ring to complete the heating of the water inside the valve body. Then, the insulation layer structure ensures that the heat generated during the heating is not easily lost. Compared with the case where no antifreeze component is provided on the conventional valve body, the technical solution adopted by the utility model can realize the monitoring and heating of the water in the valve body, and ensure that the water does not freeze due to cooling, resulting in the valve body structure being damaged due to ice expansion and shortening the service life. The overall structure is compact and easy for staff to install and maintain, reducing the later maintenance cost, and solving the problem that the existing ball valve has no antifreeze auxiliary device, which makes the ball valve easy to be damaged in a low temperature environment and reduces the service life of the ball valve.

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] The utility model provides an anti-freeze cracking ball valve, comprising a valve body 1, which is made of corrosion-resistant material, the left end of the valve body 1 being a water inlet 101, the right end of the valve body 1 being a water outlet 102, a valve core 103 being rotatably connected to the valve body 1, a working block 2 being installed on the top of the valve body 1, a rotating shaft 3 being fixedly connected to the top of the valve core 103, sealing rings 4 being fixedly connected to the valve body 1 on both sides of the valve core 1, a heating ring 5 being embedded in the valve body 1, a heating resistor 501 being installed in the heating ring 5, a control box 502 being fixedly connected to the left side of the working block 2, a power supply 503 being embedded in the control box 502, and the control box 502 being connected to the heating resistor 501 via an electric wire 504, a motor 301 being installed on the top of the working block 2, a rotor 302 being rotatably connected to the motor 301, the rotating shaft 3 being communicated with the rotor 302, and the heating ring 5 being an annular structure.

[0018] When the anti-freeze crack ball valve is actually in use, the temperature monitor 505 on the right side of the working block 2 cooperates with the temperature measuring tube 506 to monitor the water inside the valve body 1 in real time. Once the temperature drops, the control box 502 structure is installed on the left side of the working block 2. The control box 502 is embedded with a power supply 503 structure. The power supply 503 cooperates with the wire 504 to supply power to the heating ring 5 in the valve body 1, so that the heating resistor 501 in the heating ring 5 heats up after receiving the power supply, forming a relatively high temperature in the valve body 1, thereby heating the water inside the valve body 1 and avoiding the water freezing due to low temperature and expanding inside the valve body 1 to cause damage to the valve body 1 structure. At the same time, the outer wall of the valve body 1 is fixedly connected with a thermal insulation layer 6 structure, so that the heat generated in the valve body 1 is not easily lost. By installing a working Block 2 structure, and then install a temperature monitor 505 on the right side of the working block 2 and a control box 502 structure on the left side. First, the temperature monitor 505 cooperates with the temperature measuring tube 506 to monitor the water temperature inside the valve body 1 in real time. After detecting an abnormal temperature, the control box 502 cooperates with the power supply 503 to power the heating resistor 501 in the heating ring 5 to complete the heating of the water inside the valve body 1. The insulation layer 6 structure ensures that the heat generated during the heating is not easily lost. Compared with the conventional valve body 1 without an antifreeze component, the technical solution adopted by the utility model can realize the monitoring and heating of the water in the valve body 1, ensuring that the water does not freeze due to cooling, resulting in the valve body 1 structure being damaged due to ice expansion, shortening the service life, and the overall structure is compact, easy for staff to install and maintain, and reduce the later maintenance cost.

[0019] like Figure 1As shown, the outer wall of the valve body 1 is fixedly connected to an insulation layer 6, and the insulation layer 6 is made of corrosion-resistant material. The right side of the working block 2 is fixedly connected to a temperature monitor 505, and a temperature measuring tube 506 is installed at the bottom of the temperature monitor 505. The temperature measuring tube 506 is connected to the interior of the valve body 1.

[0020] The effect achieved by the entire embodiment 1 is that, during use, the water inside the valve body 1 is monitored in real time by the temperature monitor 505 on the right side of the working block 2 in conjunction with the temperature measuring tube 506, thereby ensuring the monitoring of the water temperature inside the valve body 1.

[0021] Working principle: The temperature monitor on the right side of the working block cooperates with the temperature measuring tube to monitor the water inside the valve body in real time. Once the temperature drops, the control box structure installed on the left side of the working block has a built-in power supply structure. The power supply cooperates with the wires to supply power to the heating ring in the valve body, so that the heating resistor in the heating ring heats up after receiving the power supply, forming a relatively high temperature in the valve body, thereby heating the water inside the valve body and avoiding the water freezing due to low temperature and expanding inside the valve body to cause damage to the valve body structure. At the same time, an insulation layer structure is fixedly connected to the outer wall of the valve body, so that the heat generated in the valve body is not easily lost.
