TECHNICAL FIELD
[0001] The present application relates to the technical field of liquid chlorine cylinders, in particular to a portable liquid chlorine cylinder valve leak stopper. BACKGROUND
[0002] Liquid chlorine is a strong oxidizing agent, which can be used for bleaching in the textile and paper industry, purification and disinfection of tap water, smelting of magnesium and other metals, and can also be used for preparing various chlorine-containing compounds such as pesticides, detergents, plastics, rubber, medicines, etc. However, in many fields, the amount of liquid chlorine used is usually small, so steel cylinders are used for loading, unloading and transportation. Liquid chlorine is corrosive and will form hydrochloric acid when it comes into contact with water, thereby causing serious corrosion to metals and other materials. The liquid chlorine outlet of the liquid chlorine cylinder valve is the interface between liquid chlorine and air, so the liquid chlorine cylinder valve will slowly corrode after long-term use, eventually causing damage to the internal plunger of the liquid chlorine cylinder valve, and liquid chlorine leakage. At the same time, the external threads of the liquid chlorine outlet of the liquid chlorine cylinder valve will also be corroded due to reasons such as filling and unloading, thereby making it impossible to seal with a cap.
[0003] In related technologies, the entire valve is covered or replaced with a dead cylinder processor, but this method is time-consuming and labor-intensive, and if it leaks during transportation, it is not convenient for temporary treatment. The utility model patent with the authorization announcement number CN202733433U discloses a portable liquid chlorine cylinder valve gas sealing stoppage kit for emergency treatment of liquid chlorine cylinder valve, which includes a threaded pressure lever, a threaded pressure lever fixed support steel plate, a liquid chlorine cylinder valve protection steel plate bolt fixed support and a bowl type leak stoppage rubber sheet fixing device. The two valves of the liquid chlorine cylinder are covered by the bowl type structure to prevent chlorine gas leakage, and the leak stoppage rubber sheet is used to increase the sealing between the bowl type leak stoppage rubber sheet fixing device and the surface of the cylinder.
[0004] In view of the above related technologies, on the one hand, the 800L (1 ton load) level liquid chlorine cylinder is relatively large, and the sealing tool required is also relatively large, which affects its convenience and usability, and the sealing surface of the cylinder is large, which makes sealing difficult. On the other hand, there is no available pressure relief port after sealing, and the sealing device still needs to be opened during subsequent inspection and maintenance, causing subsequent chlorine gas leakage. UTILITY MODEL CONTENT
[0005] In order to more quickly and simply handle the leaking liquid chlorine cylinder valve, the present application provides a portable liquid chlorine cylinder valve leak stopper.
[0006] The portable liquid chlorine cylinder valve leak stopper provided by the present application adopts the following technical scheme:
[0007] The utility model provides a portable liquid chlorine steel bottle valve leak stopper, including the fixed base for containing liquid chlorine steel bottle valve, the leak stoppage board for plugging the bottle valve export and the threaded pressure lever for connecting the leak stoppage board and the fixed base, the threaded pressure lever passes through the leak stoppage board and is connected with the fixed base rotationally.
[0008] By adopting the above technical scheme, the fixed base for containing liquid chlorine steel bottle valve and the leak stoppage board for plugging the bottle valve export can accurately plug the bottle valve export, avoiding sealing difficulty. The threaded pressure lever connects the leak stoppage board and the fixed base, and the pressure on the leak stoppage board can be adjusted by rotating the threaded pressure lever, so that the plugging force can be accurately controlled according to the actual situation, ensuring good sealing effect under different leakage conditions and enhancing the reliability of plugging. The leak stopper has a relatively simple structure, and compared with the large plugging tool required by the existing 800L level liquid chlorine steel cylinder, the overall size is smaller, facilitating carrying and operation, and the use convenience in different scenes can be effectively improved. Whether in the factory or in transit, the leak stopper can be more conveniently carried and quickly taken, and is suitable for plugging liquid chlorine steel bottle valves of various specifications, not limited to steel cylinders of a specific size, improving the universality and applicability of the leak stopper.
[0009] Further, the fixed base has a bottom plate and vertical plates arranged on both sides of the bottom plate, the bottom plate and the vertical plates together form a clamping groove for placing the liquid chlorine steel bottle valve, and the vertical plate is provided with a matching groove near the leak stoppage board for inserting the threaded pressure lever.
[0010] By adopting the above technical scheme, the fixed base has a clamping groove formed by the bottom plate and the vertical plates on both sides, providing accurate positioning and stable support for the liquid chlorine steel bottle valve. The bottle valve can be accurately placed in the clamping groove, ensuring that it does not shake or shift during plugging, improving the stability and reliability of the plugging operation. The matching groove provides guidance and space for the operation of the threaded pressure lever, allowing the operator to more conveniently rotate the threaded pressure lever, so that it can be accurately screwed with the fixed base, facilitating the adjustment of the pressure on the leak stoppage board and improving the convenience and accuracy of the operation.
[0011] Further, the leak stoppage board is provided with a chlorine-resistant gasket near the fixed base.
[0012] By adopting the above technical scheme, liquid chlorine is corrosive, and the chlorine-resistant gasket can act as a protective barrier to isolate the leak stoppage board from liquid chlorine, reducing direct corrosion of the leak stoppage board by liquid chlorine and prolonging the service life of the leak stoppage board. The chlorine-resistant gasket has a certain flexibility and elasticity, and can fill the small gaps between the leak stoppage board and the bottle valve due to unevenness of the surfaces of the components or size differences, making the plugging more airtight and effectively preventing liquid chlorine from leaking through these gaps, improving the sealing effect of the leak stopper.
[0013] Further, the threaded pressure lever is provided with a handle at one end away from the fixed base.
[0014] By adopting the above technical scheme, the handle provides a convenient and comfortable force point for the operator. Compared with directly operating the threaded pressure lever, the handle enables the operator to more flexibly control the direction and size of the force and more accurately adjust the pressure on the plugging plate according to actual needs, so that the plugging operation is more smooth and accurate.
[0015] Further, the plugging plate is provided with a pressure relief channel at the position of the bottle valve outlet.
[0016] By adopting the above technical scheme, after plugging the liquid chlorine cylinder valve, the liquid chlorine in the cylinder may still be in a certain pressure state. With the influence of factors such as changes in environmental temperature, the pressure in the cylinder may further increase. The pressure relief channel can provide a release path for the pressure in the cylinder, prevent excessive accumulation of pressure, avoid dangerous situations such as the plugging device being washed away or the cylinder being broken due to excessive pressure, and improve the safety after plugging.
[0017] Further, the size of the pressure relief channel is smaller than the size of the bottle valve outlet.
[0018] By adopting the above technical scheme, the smaller size of the pressure relief channel can realize the pressure relief function without causing great interference to the sealing state of the plugging plate and the bottle valve outlet surface. The good sealing of the plugging plate and the bottle valve outlet surface effectively prevents liquid chlorine leakage, reduces harm to personnel and the environment, and together with the pressure relief function, builds a safety protection system. The pressure relief channel with a size smaller than the bottle valve outlet can accurately control the pressure relief amount and speed, avoiding the situation that the pressure is instantaneously unbalanced or a large amount of liquid chlorine is sprayed due to too fast pressure relief. The operator can finely adjust the pressure in the cylinder through the pressure relief channel according to the actual situation, ensuring that the pressure is always within a safe and appropriate range.
[0019] Further, the plugging plate is provided with a switch device on the side away from the fixed base for controlling the opening and closing of the pressure relief channel.
[0020] By adopting the above technical scheme, when the plugging is completed on site and the pressure relief condition is not met, the switch device is used to quickly close the pressure relief channel, ensuring that the plugging plate and the bottle valve outlet surface form a complete and tight seal. The liquid chlorine leakage is stopped in the first time, preventing the spread of dangerous substances and ensuring the safety of personnel and the environment, and gaining buffer time for subsequent work. Once the pressure relief condition is met, the switch device can be easily opened to perform pressure relief operation through the pressure relief channel. The small size of the pressure relief channel can accurately control the pressure relief amount and speed, avoiding the situation that the pressure is instantaneously unbalanced or a large amount of liquid chlorine is sprayed, ensuring that the pressure in the cylinder is smoothly reduced to a safe range, and realizing flexible and safe pressure regulation.
[0021] Further, the switch device is connected with a joint for connecting the decontamination system at one end away from the blocking plate.
[0022] By adopting the technical scheme, the joint can be connected with the chlorine gas extraction system of the factory, and the chlorine gas discharged in the pressure relief process can be accurately guided to the decontamination system, so as to avoid direct discharge of the chlorine gas into the atmosphere and prevent pollution of the air, soil and water source. When the site does not have pressure relief conditions, the switch device can be used to close the pressure relief channel, and sealing operation is performed first to ensure the safety of the liquid chlorine cylinder. The joint is connected with the decontamination system, so that the whole liquid chlorine cylinder valve leakage and subsequent treatment process are more perfect. From leakage, pressure relief to chlorine harmless treatment, a complete closed-loop system is formed, and the control ability of the factory on the liquid chlorine leakage risk is improved, and the safety production guarantee is enhanced.
[0023] In summary, the present application has at least one of the following beneficial technical effects:
[0024] 1. Through the cooperative action of the fixed base, the blocking plate and the threaded pressure lever, accurate blocking of the liquid chlorine cylinder valve outlet is realized, the blocking force can be flexibly adjusted, different leakage conditions can be adapted to, the leakage reliability is enhanced, and the structure is simple, the volume is small, the operation is convenient, and the universality is strong;
[0025] 2. By using the chlorine-resistant gasket, the pressure relief channel and the related design, liquid chlorine corrosion is effectively prevented, the sealing effect is improved, the pressure in the cylinder is reasonably controlled, the risk caused by excessive pressure is prevented, and a safety protection system is constructed;
[0026] 3. By means of the switch device and the joint connected with the decontamination system, the pressure relief channel can be flexibly controlled according to the site conditions, immediate sealing and subsequent safe pressure relief can be realized, and the pressure relief chlorine gas can be guided to the decontamination system, the leakage treatment process is improved, and the environmental protection and safety production guarantee are strengthened.

DETAILED DESCRIPTION
[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will combine the drawings to make further detailed description of the present application. Figures 1-3 and examples.
[0032] The present application discloses a portable liquid chlorine cylinder valve 5 leak stopper. Referring to Figure 1 and Figure 2 , the portable liquid chlorine cylinder valve 5 leak stopper comprises a fixed base 1, a leak stopper 2, a threaded pressure lever 3 and a chlorine-resistant gasket 4. The fixed base 1 is used to accommodate the liquid chlorine cylinder valve 5, the leak stopper 2 is used to block the valve outlet 6, and the threaded pressure lever 3 is used to connect the leak stopper 2 and the fixed base 1.
[0033] Referring to Figure 2 and Figure 3 , the fixed base 1 comprises a bottom plate 11 and vertical plates 12 vertically arranged and integrally connected on both sides of the bottom plate 11, and the bottom plate 11 and the vertical plates 12 together form a clamping groove 13. In actual operation, the liquid chlorine cylinder valve 5 is placed in the clamping groove 13 for fixation. In this embodiment, the size and shape of the clamping groove 13 are set according to the specifications of the liquid chlorine cylinder valve 5 to ensure that the valve can be tightly and stably embedded therein, providing positioning and support for subsequent leak stoppage operation.
[0034] The leak stopper 2 is pre-formed with a chlorine-resistant gasket 4 on the side close to the fixed base 1 by rough grinding, and the chlorine-resistant gasket 4 is accurately attached to the fitting surface to ensure that the chlorine-resistant gasket 4 can completely cover the area where the leak stopper 2 and the valve may come into contact. The chlorine-resistant gasket 4 has flexibility and elasticity, and when the leak stopper 2 is close to the valve outlet 6 under the action of the threaded pressure lever 3, it can fill the small gap caused by the unevenness or size difference between the leak stopper 2 and the valve surface, enhancing the tightness of the blockage, and at the same time playing the role of isolating liquid chlorine and preventing it from corroding the leak stopper 2.
[0035] The upright plate 12 is provided with a matching groove 121 on the side close to the plugging plate 2, which is used for subsequent insertion of the threaded pressure lever 3 and forms a rotating connection with the threaded pressure lever 3, so that the threaded pressure lever 3 can rotate flexibly. A threaded through hole 21 is formed at the corresponding position of the plugging plate 2, and the chlorine-resistant gasket 4 is also provided with a threaded through hole 21 at the corresponding position for the threaded pressure lever 3 to pass through. The threaded pressure lever 3 is sequentially inserted through the threaded through hole 21 of the chlorine-resistant gasket 4 and the threaded through hole 21 of the plugging plate 2, and the threaded pressure lever 3 is threadedly connected with the threaded through holes 21 of the two.
[0036] When the threaded pressure lever 3 rotates, it can drive the plugging plate 2 to move close to or away from the bottle valve outlet 6 due to the threaded connection relationship between the threaded pressure lever 3 and the plugging plate 2 and the chlorine-resistant gasket 4. By rotating the threaded pressure lever 3, the pressure exerted on the plugging plate 2 can be adjusted, so that the plugging plate 2 can tightly fit the bottle valve outlet 6 and achieve the plugging of the bottle valve outlet 6. Since the chlorine-resistant gasket 4 is threadedly connected with the threaded pressure lever 3, when the threaded pressure lever 3 adjusts the position of the plugging plate 2, the chlorine-resistant gasket 4 can also move stably and maintain a good sealing state.
[0037] A handle 31 is installed at the end of the threaded pressure lever 3 away from the fixed base 1. The handle 31 can be fixed on the threaded pressure lever 3 by welding, threaded connection or other firm connection methods. The operator can more conveniently and flexibly exert force on the threaded pressure lever 3 by holding the handle 31, so as to more accurately control the rotation of the threaded pressure lever 3, and then adjust the pressure on the plugging plate 2, making the plugging operation more smooth and accurate.
[0038] In this embodiment, the plugging plate 2 is provided with a pressure relief channel 22 at the position corresponding to the bottle valve outlet 6. The size of the pressure relief channel 22 is smaller than that of the bottle valve outlet 6, so as to ensure that the pressure relief function is realized without causing great interference to the sealing state of the plugging plate 2 and the bottle valve outlet 6.
[0039] A switch device 23 for controlling the opening and closing of the pressure relief channel 22 is installed on the side of the plugging plate away from the fixed base 1. The switch device 23 facilitates the operator to quickly and accurately control the opening and closing of the pressure relief channel 22. A connector 24 for connecting the decontamination system is connected to the end of the switch device 23 away from the plugging plate. The connector 24 is tightly connected with the switch device 23, so as to ensure that the chlorine gas can be smoothly guided to the decontamination system through the connector 24 during the pressure relief process. When it is necessary to connect the plugging device with the chlorine gas extraction system of the factory, the connector 24 is connected with the corresponding interface of the chlorine gas extraction system, so as to ensure good connection and prevent chlorine gas leakage.
[0040] In actual use of the portable liquid chlorine cylinder valve 5 leak stopper, first place the liquid chlorine cylinder valve 5 in the clamping groove 13 of the fixed base 1, then install the chlorine-resistant gasket 4 and the leak stopper plate 2 in turn, make the threaded pressure lever 3 pass through the threaded through hole 21 of the chlorine-resistant gasket 4 and the leak stopper plate 2 and complete the threaded cooperation. According to the site conditions, if immediate leak stoppage operation is required and pressure relief is not required, the leak stopper plate 2 is tightly sealed to the cylinder valve outlet 6 by rotating the threaded pressure lever 3, and the switch device 23 is closed to ensure the sealing effect. If the pressure relief condition is met after the leak stoppage is completed, the switch device 23 is opened, the pressure in the cylinder is released through the pressure relief channel 22, and the discharged chlorine gas is guided to the harm removal system through the joint 24 for treatment. If the site does not have pressure relief conditions, the switch device 23 is closed to ensure sealing, and then the pressure relief operation is performed when the conditions are met.
[0041] The implementation principle of the portable liquid chlorine cylinder valve 5 leak stopper according to the embodiment of the application is as follows: when leakage occurs at the liquid chlorine outlet of the liquid chlorine cylinder valve 5 and the cylinder valve cannot be tightly closed, the leak stopper is stably fixed at the liquid chlorine cylinder valve 5 and precisely positioned by using the fixed base 1 and the clamping groove 13 formed thereby. Then, the leak stopper plate 2 with the chlorine-resistant gasket 4 is covered on the outlet of the liquid chlorine cylinder valve 5. By rotating the handle 31 at one end of the threaded pressure lever 3, the threaded pressure lever 3 is rotated, and since the threaded pressure lever 3 is in threaded cooperation with the leak stopper plate 2 and the chlorine-resistant gasket 4, the leak stopper plate 2 is driven to approach the cylinder valve outlet 6 and apply pressure, so that the leak stopper plate 2 is tightly compacted at the outlet of the liquid chlorine cylinder valve 5, sealing is achieved, and liquid chlorine leakage is effectively avoided. When the site has conditions for pressure relief of the liquid chlorine in the liquid chlorine cylinder, the joint 24 at one end of the pressure relief channel 22 is connected to the pipeline connected to the harm removal system, and the switch device 23 on the pressure relief channel 22 is opened, so that the pressure in the cylinder is released through the pressure relief channel 22, and the discharged chlorine gas is guided to the harm removal system for harmless treatment through the joint 24. If the site does not have pressure relief conditions, the switch device 23 is closed, and the joint 24 is sealed, to ensure that the leak stopper maintains a good sealing state during the subsequent waiting process and prevents liquid chlorine leakage.
[0042] The above are preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
