Description

Technical Field

[0001] The utility model relates to the technical field of flange ball valve protection, and more specifically, to a protection structure for a flange ball valve. Background Technique

[0002] A flange ball valve is a ball valve integrated with flange connection. A ball valve is a rotary switch valve suitable for the opening and closing and regulation of media in pipelines. The flange ball valve adds flange connection on the basis of the ball valve, which is convenient for installation and connection to the pipeline system. The protection structure for the flange ball valve mainly plays a protective role for the flange ball valve, usually a fixed cover for protecting the flange ball valve.

[0003] However, the existing protection structure for flange ball valves usually uses a fixed cover to protect the flange ball valve from dust. Whenever valve adjustment is required, personnel need to open the protective cover to adjust the ball valve. In the process of repeatedly disassembling and assembling the protective cover, it will undoubtedly increase the labor intensity of personnel. Some protective covers are provided with clamping plates on the top to seal the top of the ball valve. When adjusting, the clamping plate can be opened to adjust the ball valve. Although this facilitates the adjustment of the ball valve without disassembling the protective cover, in use, it is often forgotten to close the clamping plate due to carelessness of personnel, which will undoubtedly bring great trouble to the protective use. Moreover, the existing protective cover is only composed of a single plate, and it is extremely difficult to completely and effectively isolate external moisture, and this moisture is extremely easy to cause rust and corrosion to the valve seat and the adjusting rod. Once the ball valve adjusting seat is corroded, it will affect the later adjustment of the ball valve and reduce its service life;

[0004] Moreover, in an extremely low-temperature environment, the medium in the existing ball valve protection device may freeze or solidify, resulting in the blockage of the valve or the influence on the operation. Moreover, in a cold environment, the seals of the valve may also fail due to freezing, resulting in a decrease in the sealing performance, which brings great trouble to the actual use.

[0005] In view of this, we propose a protection structure for a flange ball valve. Content of the Utility Model

[0006] 1. Technical Problems to be Solved

[0007] The purpose of the utility model is to provide a protection structure for a flange ball valve to solve the problems of poor protection effect, inconvenient adjustment during the protection process, and poor protection effect in a cold environment as mentioned in the above background technique.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows: During the use of the valve, the ball valve body can be protected by the lower fixed shell and the upper fixed shell. When it is necessary to adjust the ball valve body, only need to insert the hand into the through groove, and then grasp the adjusting valve through the rubber leather sleeve, and then rotate the adjusting valve to adjust the ball valve. During this rotation process, the rubber leather sleeve is connected to the rotating ring itself, and the rotating ring is rotatably connected in the through groove. Therefore, it can cooperate with the balls arranged at the bottom of the rotating ring and synchronously rotate with the rotating action of the hand-rotated adjusting valve, so that it is not necessary to disassemble the protective cover or open the protective cover back and forth every time the ball valve is adjusted, reducing the operation burden of personnel, and also avoiding the situation that personnel are careless and forget to close and protect the ball valve body. Since the closed protective space is not opened during the adjustment process, the risk of pollutants entering can also be better reduced. And during the protection process, the moisture in the closed protective space can be adsorbed by the drying plate, reducing the rusting and corrosion of the ball valve body, and further improving the convenience and practicality of its use;

[0017] When used in an extremely low-temperature environment, the temperature sensor on the inner wall of the lower fixed shell can be used to monitor the temperature of the enclosed protection space. Once the temperature exceeds the threshold, the controller will be used to control the electric heating tube to raise the temperature of the enclosed space, and the heat insulation layer inside the lower fixed shell and the upper fixed shell will be used to keep the temperature, reduce heat loss, lower the energy consumption required for heating, avoid the situation that the ball valve body is blocked or its operation is affected due to the freezing of the medium, and effectively prevent the sealing element from freezing, thus avoiding affecting the sealing performance of the ball valve body.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0026] A protection structure for a flange ball valve, including a ball valve main body 100. Lower fixed shells 200 and upper fixed shells 300 are respectively arranged on the outer wall of the ball valve main body 100. Connection frames 240 are arranged on the front and rear outer walls of the lower fixed shell 200. Electric heating tubes 241 are arranged inside multiple connection frames 240. A controller 250 is arranged on the front outer wall of the lower fixed shell 200. A temperature sensor 230 is arranged on the inner wall of the lower fixed shell 200. Multiple electric heating tubes 241 and the temperature sensor 230 are electrically connected in series with the controller 250;

[0027] In some embodiments: The temperature sensor 230 generally adopts a thermistor sensor or a thermocouple sensor, which can accurately measure the temperature and transmit the signal to the controller 250. The controller 250 sets the threshold temperature, monitors the sensor signal, and controls the heating operation of the electric heating tube 241 according to the set conditions. The electric heating tube 241 is composed of a heating wire, an insulating layer, and an external protective layer. When current passes through the heating wire, the heating wire generates heat and transfers it to the enclosed space, thereby raising the temperature of the space, which can better meet the use requirements in extremely low temperature environments.

[0028] Drying components are arranged on the front and rear outer walls of the upper fixed shell 300. The drying components include a fixed frame 320. A through groove 360 is arranged on the top of the upper fixed shell 300. A rotating ring 370 is rotatably connected inside the through groove 360.

[0029] Specifically, fixing screws one 210 are threadedly sleeved on the front and rear outer walls of the lower fixed shell 200. The fixing screws one 210 are matched with the limit thread grooves 110, which is convenient for installing the lower fixed shell 200.

[0030] Furthermore, fixing screws two 310 are threadedly connected to the front and rear outer walls of the upper fixed shell 300. Multiple fixing screws two 310 are matched with the limit thread grooves 110, which is convenient for installing the upper fixed shell 300.

[0031] Furthermore, an insulating layer 220 is sleeved inside the top of the lower fixed shell 200, and an insulating layer 220 made of the same material is sleeved inside the upper fixed shell 300, which is convenient for using the insulating layer 220 to reduce heat loss.

[0032] Furthermore, a clamping frame 330 is clamped inside the fixing frame 320. A drying plate 340 is arranged inside the clamping frame 330, and a pull rod 350 is arranged at the top of the clamping frame 330, which is convenient for replacing the drying plate 340. The drying plate 340 is a silica gel drying plate.

[0033] It should be noted that a ball 371 is movably clamped on the circumferential outer wall of the rotating ring 370, and a rubber sheath 372 is arranged inside the rotating ring 370.

[0034] In some embodiments: while preventing external dust from entering, the rubber sheath 372 is also more convenient for adjusting the ball valve body during protection, and has better gripping ability, reducing the situation of the palm sliding with the regulating valve during rotation.

[0035] In some embodiments: the device can be powered by an external conventional power supply.

[0036] In addition, the circuits, electronic components and modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method.

[0037] Working principle: During the use of the valve, the ball valve body 100 can be protected by the lower fixed shell 200 and the upper fixed shell 300. When it is necessary to adjust the ball valve body 100, just insert the hand into the through groove 360, and then grasp the adjusting valve through the rubber sleeve 372, and then rotate the adjusting valve to adjust the ball valve. During this rotation process, the rubber sleeve 372 rotates synchronously because it is itself connected to the rotating ring 370, and the rotating ring 370 is rotatably connected in the 360 through groove. Therefore, it can cooperate with the ball 371 provided at the bottom of the rotating ring 370 to synchronously rotate with the rotation action of the hand-rotated adjusting valve, so that it is not necessary to disassemble the protective cover or open and close the protective cover back and forth every time the ball valve is adjusted, reducing the operation burden of personnel, and also avoiding the situation that personnel carelessly forget to close and protect the ball valve body 100. Since the closed protective space is not opened during the adjustment process, it can also better reduce the risk of pollutants entering. Moreover, during the protection process, the moisture in the closed protective space can be adsorbed by the drying plate 340, reducing the situation of rust and corrosion of the ball valve body 100. When used in an extremely low temperature environment, the temperature sensor 230 on the inner wall of the lower fixed shell 200 can be used to monitor the temperature of the closed protective space. Once the temperature exceeds the threshold, the controller 250 will control the electric heating tube 241 to raise the temperature of the closed space, avoiding the situation that the ball valve body 100 is blocked or its operation is affected due to the freezing or solidification of the medium, and also effectively preventing the sealing element from being frozen and avoiding affecting the sealing performance of the ball valve body 100.
