Abstract

The utility model relates to a combined gate cover, which is composed of a cover body, a sealing sleeve and a sealing ring, wherein the sealing sleeve is installed in the cover body by screw threads, the sealing ring is sheathed on the sealing sleeve, and gaps are arranged among the sealing ring, the sealing cover body and the sealing sleeve; the sealing sleeve adopts strong corrosion resistance stainless steel materials, and the sealing sleeve is provided with a round hole which is used for screwing and releasing screw thread installation tools. The combined gate cover enables easily corrosive parts to be designed into dismountable parts, small parts are needed to be replaced, and the replacement after corrosion damage is economic and convenient; the utility model is not easy to be corroded after changing corrosion resistant materials, so has the advantages of long service life, labor saving and goods saving.

Description

The combined gate lid
One, technical field
The utility model is the combined gate lid, belongs to engineering goods.
Two, background technique
Gate in use will contact various Korrosionsmediums, the essential gate that uses corrosion resistance of some places, but because the cost problem some places just do not use the gate of corrosion resistance, though the gate that uses as oil-field flooding does not contact strong corrosive media, also has certain corrosivity but inject water, particularly the easiest being corroded in place of in the gate lid seal ring being installed.In a single day be corroded, gate will be missed herein, occur this situation at present at the scene and will change gate or gate lid, cause the working life of gate or gate lid short, and water filling work often stops, and increases Master Cost, the consumption manpower, and economic loss is serious.
Three, summary of the invention
The purpose of this utility model is a kind of combined gate lid of design, makes its gate lid be not easy to be corroded, gate lid long service life.
The purpose of this utility model is to realize like this, it is made up of lid, stuffing box gland, seal ring, stuffing box gland is installed in the lid with screw thread, ring set is on stuffing box gland, gap between seal ring sealing lid and the stuffing box gland, stuffing box gland adopts corrosion-resistant strong stainless steel material, has on the stuffing box gland to screw and unload the circular hole that loose screw thread setting tool is used.
The beneficial effects of the utility model are: the position that the combined gate lid will be corroded easily is designed to dismountable parts, need the parts of replacing little, it is economical convenient to change after the corrosion and damage, and because be not easy corrosion after changing resistant material into, long service life, use manpower and material resources sparingly, have comparatively remarkable economic efficiency.
Four, description of drawings
Accompanying drawing is an erection drawing of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Among the figure: the 1st, lid, the 2nd, stuffing box gland, the 3rd, seal ring.Be that the utility model is made up of lid 1, stuffing box gland 2, seal ring 3.Stuffing box gland 2 usefulness screw threads are installed in the lid 1, seal ring 3 is sleeved on the stuffing box gland 2, gap between seal ring 3 sealing lids 1 and the stuffing box gland 2, stuffing box gland 2 adopts corrosion-resistant strong stainless steel material, has on the stuffing box gland 2 to screw and unload the circular hole that loose screw thread setting tool is used.
