Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment, and in particular to a chemical pipeline safety cover. Background Art

[0002] Chemical pipelines are pipelines for transporting toxic, harmful, and corrosive media. They are mainly used in the pharmaceutical, metallurgical, environmental protection, water supply and drainage, petroleum and other industries. They are widely used. When transporting gases, chemical pipelines use sealing gaskets to seal and protect the joints of chemical pipelines. However, after the sealing gaskets have been used for a period of time, they age and easily cause gas leakage. However, the sealing gaskets are not easy to safely protect the leaked harmful gases, which can easily cause the harmful gases to float everywhere and pollute the environment.

[0003] Therefore, there is an urgent need for a chemical pipeline safety cover to solve the problem that harmful gases are easily leaked from the chemical pipeline connection. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a chemical pipeline safety cover, which has the advantage of preventing the leakage of harmful gases and solves the problem that harmful gases easily leak from the joints of chemical pipelines.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a chemical pipeline safety cover, comprising a chemical pipeline body, an upper protective cover and a lower protective cover, wherein the upper protective cover and the lower protective cover are sleeved on the outer surface of the chemical pipeline body, a warning mechanism is arranged on the top of the upper protective cover, and a sealing mechanism is arranged on the inner side of the upper protective cover and the lower protective cover;

[0006] The warning mechanism includes a support tube, a fixing plate, a connecting rod, a rubber sheet, a spring and a protrusion.

[0007] When too much harmful gas leaks between the upper protective cover and the lower protective cover, the air pressure between the upper protective cover and the lower protective cover will increase, and the air pressure will push the rubber sheet, and the rubber sheet will push the protrusion upward through the connecting rod, so that the protrusion will pop up, making it convenient for the staff to observe the leakage of harmful gas, and convenient for the staff to maintain the chemical pipeline body in time, making the safety cover more convenient to use.

[0008] Preferably, a circular notch is provided at a position on the top of the support tube corresponding to the protrusion.

[0009] Preferably, the outer surface of the rubber sheet is slidably connected to the inner surface of the support tube.

[0010] Preferably, the sealing mechanism includes screws, sealing groove 1, sealing sheet 1, sealing groove 2 and sealing sheet 2, the upper protective cover and the lower protective cover are fixedly connected by screws, the sealing groove 1 and the sealing groove 2 are opened on the inner side of the upper protective cover, and the sealing sheet 1 and the sealing sheet 2 are respectively bonded to the inner sides of the sealing groove 1 and the sealing groove 2.

[0011] Preferably, the inner sides of the sealing sheet 1 and the sealing sheet 2 are pressed tightly against the top of the lower protective cover.

[0012] Preferably, the first sealing sheet is an arc-shaped structure, and the second sealing sheet is a U-shaped structure.

[0013] In summary, the present application includes at least one of the following beneficial effects:

[0014] 1. The chemical pipeline safety cover, when the upper protective cover and the lower protective cover are installed on the outside of the connection of the chemical pipeline body, can protect the leaked harmful gas, so that the harmful gas is not easy to leak into the external environment. At the same time, when the harmful gas between the upper protective cover and the lower protective cover leaks too much, the air pressure between the upper protective cover and the lower protective cover will increase, and the air pressure pushes the rubber sheet, and the rubber sheet pushes the protrusion upward through the connecting rod, so that the protrusion pops up, which is convenient for the staff to observe the leakage of harmful gas and convenient for the staff to maintain the chemical pipeline body in time.

[0015] 2. For the chemical pipeline safety cover, when the screws connect the upper protective cover and the lower protective cover together, the connection position of the upper protective cover and the lower protective cover is sealed by the sealing sheet 1 and the sealing sheet 2, thereby preventing the leakage of harmful gases and making the safety cover better used.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-4 A chemical pipeline safety cover comprises a chemical pipeline body 1, an upper protective cover 2 and a lower protective cover 3. The upper protective cover 2 and the lower protective cover 3 are sleeved on the outer surface of the chemical pipeline body 1. A warning mechanism is arranged on the top of the upper protective cover 2, and a sealing mechanism is arranged on the upper protective cover 2 and the inner side of the upper protective cover 2.

[0023] Through the above technical solution, the upper protective cover 2 and the lower protective cover 3 are mounted on the connection of the chemical pipeline body 1, so that harmful gases are not easily leaked into the external environment. At the same time, the warning mechanism can promptly report the leakage of harmful gases to the staff, making the safety cover more convenient to use.

[0024] Specifically, the warning mechanism includes a support tube 111, a fixing plate 112, a connecting rod 113, a rubber sheet 114, a spring 115 and a protrusion 116. The support tube 111 is welded to the top of the upper protective cover 2, the fixing plate 112 is welded to the inner surface of the support tube 111, the outer surface of the connecting rod 113 is slidably connected to the inner side of the fixing plate 112, the rubber sheet 114 is welded to the bottom of the connecting rod 113, and both ends of the spring 115 are arranged at the bottom of the fixing plate 112 and the top of the rubber sheet 114. The outer surface of the rubber sheet 114 is slidably connected to the inner surface of the support tube 111, the protrusion 116 is welded to the top of the connecting rod 113, the outer surface of the protrusion 116 is slidably connected to the inner side of the support tube 111, and a circular notch is provided at the top of the support tube 111 corresponding to the protrusion 116.

[0025] Through the above technical solution, one end of the spring 115 is welded to the fixing plate 112, and the other end of the spring 115 is welded to the top of the rubber sheet 114. When harmful gas leaks at the connection of the chemical pipeline body 1, the air pressure between the upper protective cover 2 and the lower protective cover 3 will increase, and the air pressure pushes the rubber sheet 114. When the rubber sheet 114 moves upward, it squeezes the spring 115. The rubber sheet 114 pushes the protrusion 116 upward through the connecting rod 113, so that the protrusion 116 pops up, which is convenient for the staff to observe the leakage of harmful gas in time.

[0026] When the connection of the chemical pipeline body 1 is overhauled and no harmful gas is leaking, the spring 115 pushes the rubber sheet 114 by its own elastic force, and the rubber sheet 114 drives the protrusion 116 to be recovered into the support tube 111 through the connecting rod 113, thereby conveniently determining whether the connection of the chemical pipeline body 1 will leak harmful gas.

[0027] Specifically, the sealing mechanism includes a screw 211, a sealing groove 1 212, a sealing sheet 1 213, a sealing groove 214 and a sealing sheet 2 215. The upper protective cover 2 and the lower protective cover 3 are fixedly connected by the screw 211. The sealing groove 1 212 and the sealing groove 214 are opened on the inner side of the upper protective cover 2. The sealing sheet 1 213 and the sealing sheet 2 215 are respectively bonded to the inner sides of the sealing groove 1 212 and the sealing groove 214. The sealing sheet 1 213 is an arc-shaped structure. The inner sides of the sealing sheet 1 213 and the sealing sheet 2 215 are pressed tightly against the top of the lower protective cover 3. The sealing sheet 2 215 is a U-shaped structure.

[0028] Through the above technical solution, when the upper protective cover 2 and the lower protective cover 3 are sleeved on the outside of the connection of the chemical pipeline body 1, after the screws 211 fix the upper protective cover 2 and the lower protective cover 3, the sealing piece 1 213 and the sealing piece 2 215 seal the connection position of the upper protective cover 2 and the lower protective cover 3, thereby preventing the leakage of harmful gases, improving the sealing effect of the safety cover, and allowing the safety cover to be better used.

[0029] During use, when excessive harmful gas leaks between the upper protective cover 2 and the lower protective cover 3, the air pressure between the upper protective cover 2 and the lower protective cover 3 will increase, and the air pressure will push the rubber sheet 114, and the rubber sheet 114 will push the protrusion 116 upward through the connecting rod 113, so that the protrusion 116 will pop up, making it convenient for the staff to observe the leakage of harmful gas, and convenient for the staff to maintain the chemical pipeline body 1 in time, so that the safety cover can be more convenient to use.

[0030] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
