Description

Safe sealed lid of preventing leaking

Technical Field

The utility model belongs to the technical field of the chemical industry apparatus technique and specifically relates to a safe sealed lid of preventing leaking for on chemical drum is related to.

Background

The chemical barrel is a tool applied to chemical industry, dye, medicine and pesticide. The plastic chemical barrel has the advantages of integral Polyethylene (PE) one-step forming, no seam, impact resistance, ageing resistance, light weight, no leakage, acid and alkali resistance, long service life, conformity with sanitary standards and the like, and the service performance is greatly superior to that of the traditional containers such as glass fiber reinforced plastic containers, plastic welding containers, steel lining rubber containers and the like.

At present, the sealing cover of the common chemical industry barrel on the market has two forms: one is that the sealing cover keeps sealing and is not permeable, when the chemical barrel with the structure is used for storing and containing some chemical solutions which are easy to be gasified by heating, when the environmental temperature is higher, the gas in the barrel can expand, and potential safety hazards are easy to generate; the other is that on the closing cap or chemical drum upper portion is provided with little through-hole, utilizes the through-hole to come to exhaust the gas of inflation in the bucket, and this kind of structure is when the chemical drum is emptyd, and solution can be followed the through-hole and flowed out.

It can be seen that the two existing structures have some advantages, but have some disadvantages, and there is a need for improvement.

Disclosure of Invention

The utility model provides a safe sealed lid of preventing leaking, its simple structure, durable when having kept the advantage separately of above-mentioned two kinds of structures, has also solved the prior art problem that both exist.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a sealed lid of preventing leaking safely, includes the lid, the lid inboard is equipped with the screw thread that can be connected with the container, be equipped with the through-hole that runs through on the lid, be fixed with on the inner wall of lid and cover the teflon membrane of through-hole.

In the above technical scheme, preferably, the cover body is further internally provided with an annular wall integrally formed with the cover body, the annular wall is arranged on an outer ring of the through hole, the inner wall of the annular wall is provided with threads, the cover body further comprises a fixing cover connected with the threads, the fixing cover is used for pressing and installing the teflon membrane on the cover body, and the fixing cover is provided with a second through hole so that gas can enter from the second through hole and pass through the teflon membrane and then be discharged from the through hole on the cover body.

In the above technical solution, as another mode, the teflon film is bonded to the cover body.

In the above technical solution, preferably, the diameter of the through hole is 0.5-5 mm.

In the above technical solution, preferably, the diameter of the second through hole is 0.5-5 mm.

In the above technical solution, preferably, there are 1 through hole.

In the above technical solution, preferably, there are 2 second through holes.

The utility model provides a safe chemical drum of preventing leaking, be connected with above-mentioned sealed lid on the liquid outlet of chemical drum.

The utility model has the advantages that: the cover body is provided with a through hole, and a Teflon film covering the through hole is fixed on the inner wall of the cover body. The gas in the barrel can be discharged to the air through the Teflon film, and the liquid can not pass through the Teflon film and still be stored in the barrel. Therefore, the air pressure in the barrel can be ensured to be safe, and the liquid can be prevented from leaking when the chemical barrel is carried or poured.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 3 is a schematic view of the connection structure of the teflon membrane and the cover body of the present invention.

Fig. 4 is a schematic view of the connection structure of the fixing cover and the cover body of the present invention.

In the figure, 1, a cover body, 2, a first thread, 3, a through hole, 4, a Teflon film, 5, an annular wall, 6, a second thread, 7, a fixed cover and 8, a second through hole are arranged.

Detailed Description

Referring to fig. 1-4, the safe and leak-proof sealing cover for being arranged on a chemical bucket comprises a cover body 1, wherein a first thread 2 capable of being connected with a container is arranged on the inner side of the cover body 1, a through hole 3 penetrating through the cover body 1 is arranged on the cover body 1, and a teflon film 4 covering the through hole 3 is fixedly bonded on the inner wall of the cover body 1. The teflon film is also called as teflon film, and is made up by using suspended teflon resin through the processes of die pressing, sintering and cooling to obtain blank, turning and rolling. The gas is discharged to the air through the Teflon film, and the liquid can not pass through the Teflon film and still be stored in the barrel.

Further, in order to ensure that the teflon membrane 4 is more firmly installed and cannot fall off. Still be equipped with in the lid 1 with lid 1 integrated into one piece's annular wall 5, annular wall 5 sets up the outer lane of through-hole 3, be equipped with second screw thread 6 on the inner wall of annular wall 5, still include with fixed lid 7 that second screw thread 6 is connected, fixed lid 7 will teflon membrane 4 pressure equipment is in on the lid 1, be equipped with two second through-holes 8 on the fixed lid 7, make gas can follow second through-hole 8 and get into and pass behind the teflon membrane 4 follow through-hole 3 on the lid 1 discharges. Wherein the diameter of the through hole 3 and the second through hole 8 is 1 mm.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
