Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 3, the present invention includes: shell 1, the inside interlude of shell 1 is equipped with dodges groove 11, dodges groove 11 inside and inlays and be equipped with sealing washer 4, and 4 one side of sealing washer are equipped with first sealing ring 3, and the opposite side is equipped with second sealing ring 2, and first sealing ring 3 and second sealing ring 2 all are located shell 1's inner wall.
In the present embodiment, it is preferable that the housing 1 is symmetrically divided into two, the two housings 1 are fixed by bolts 10, and a plurality of bolts 10 are provided.
Set up above-mentioned structure, shell 1 symmetry divide into two, the change and the equipment of the sealing washer 4 of being convenient for, first sealing ring 3 and second sealing ring 2.
In the present embodiment, the housing 1 is preferably made of PVC.
The structure is low in price, stable and not easy to be corroded by acid and alkali.
In this embodiment, the sealing ring 4 is preferably made of perfluoro rubber, and the inner wall thereof is provided with a sealing opening.
By adopting the structure, the perfluororubber has higher corrosion resistance.
In this embodiment, the first sealing ring 3 is preferably a hollow cylinder structure, and ethylene propylene diene monomer is used.
In this embodiment, the second sealing ring 2 is preferably a hollow cylinder structure, and ethylene propylene diene monomer is used.
By adopting the structure, the ethylene propylene diene monomer is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, and has excellent ozone resistance, heat resistance and aging resistance.
When the hose is used, the hose to be connected can be recorded on two sides of the interior of the product, and the method is simple.
And can realize reuse through changing sealing washer 4, second sealing ring 2 and first sealing ring 3, the joint application of sealing washer and sealing ring simultaneously, the great life who improves the product reduces and changes the frequency.
The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application.
