Abstract
The utility model relates to the technical field of fire fighting instruments, in particular to a loose flange connecting device for water inlet pipes. The loose flange connecting device comprises a loose flange and a water inlet pipe. The loose flange is sleeved on the water inlet pipe. A first annular groove is formed in the outer cylindrical face of the water inlet pipe. A semicircular clamp ring is mounted in the first annular groove. The semicircular clamping ring surrounds the first annular groove to form a ring. The semicircular clamp ring is connected with the loose flange through a screw. The loose flange is connected with the water inlet pipe through a flat key. The loose flange connecting device has the advantages that the loose flange and the water inlet pipe can be mounted and demounted repeatedly, and the application range of the loose flange is expanded; the loose flange is sleeved on the water inlet pipe and connected with the same through the flat key, the loose flange is connected with the semicircular clamp ring in the first annular groove through the screw, and accordingly relative displacement, in the axial and peripheral directions, of the loose flange and the water inlet pipe can be prevented, and the water inlet pipe does not shake during use.
Description
Technical field
The utility model relates to fire-fighting equipment technical field, particularly relates to a kind of lap joint flange connection set for intake pipe.
Background technique
The mouth of pipe connects mainly to be realized by flange, and in prior art, intake pipe adpting flange is generally welded on intake pipe, cannot disassemble from pipe; But in water pipe using process, usually need flange to disassemble from water pipe, and then install; Flange welding, on intake pipe, cannot be dismantled; This makes it in application, seriously be restricted.
Model utility content
The purpose of this utility model is: the problems referred to above that exist for prior art, provide a kind of lap joint flange connection set that can repeatedly dismantle, install from intake pipe.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of lap joint flange connection set, comprise lap joint flange and intake pipe, described lap joint flange is socketed on described intake pipe, described intake pipe external cylindrical surface is provided with first ring connected in star, in described first ring connected in star, half-round clamping ring is installed, described half-round clamping ring forms an annulus around described first ring connected in star, and described half-round clamping ring is connected with lap joint flange by screw.Described half-round clamping ring is positioned at described first ring connected in star, and form an annulus, described half-round clamping ring can not move axially along described intake pipe, described lap joint flange is socketed on described intake pipe, described half-round clamping ring and lap joint flange are connected by screw, and described lap joint flange can not move axially along intake pipe.When described lap joint flange is installed, described half-round clamping ring is arranged in described first ring connected in star, then by screw, described lap joint flange is connected with described half-round clamping ring; During dismounting flange, unclamp screw, take off half-round clamping ring, then described lap joint flange is taken off from described intake pipe; Adopt described half-round clamping ring repeatedly to mount and dismount described lap joint flange and described intake pipe.
Preferably, described lap joint flange endoporus is provided with the second annular groove, is provided with 0 RunddichtringO sealing in described the second annular groove, and described 0 RunddichtringO stuffing box gland is connected on described intake pipe.At the connection part of described lap joint flange and described intake pipe, establish described 0 RunddichtringO, the good airproof performance between intake pipe and lap joint flange, the water in intake pipe can not overflow from described connection part, has avoided the waste of fire-fighting water.
Preferably, described lap joint flange also connects by flat key with described intake pipe.When described lap joint flange connects with flat key with described intake pipe, without the relatively rotating of circumferencial direction, more firm in intake pipe using process between the two.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, lap joint flange connection set of the present utility model, described half-round clamping ring is positioned at described first ring connected in star, described lap joint flange is socketed on described intake pipe, described half-round clamping ring and lap joint flange are connected by screw, described lap joint flange and described intake pipe mount and dismount repeatedly, have expanded its application area.
2, lap joint flange connection set of the present utility model, described lap joint flange is socketed on described intake pipe, and be connected by screw with the described half-round clamping ring that is positioned at described first ring connected in star, described lap joint flange connects with described intake pipe flat key simultaneously, lap joint flange and intake pipe cannot have relative displacement at axial and circumferencial direction, in water pipe using process, can not shake, more handy.
