Abstract

The utility model provides a disassembly-free groove type pipe joint which consists of a splicing type clamp hoop, a circular rubber seal ring, a plurality of nuts and a plurality of bolts, wherein the splicing type clamp hoop is a component spliced by two arc arch pieces, and the splicing type clamp hoop is elliptic. When the disassembly-free groove type pipe joint is used for connecting two pipes, a joint part of the two connecting pipes can be completely arranged in the middle by the circular rubber seal ring which is used as a limiter, so that the disassembly-free groove type pipe joint is better for the seal of the connection of the pipes; and the disassembly-free groove type pipe joint is fast to assemble, i.e. two pipe fittings are sheathed into the circular rubber seal ring by means of butt joint rather than disassembling the splicing type clamp hoop and the circular rubber seal ring, so that the disassembly-free groove type pipe joint is simple in operation, high in work efficiency, and good in sealing performance.

Description

Exempt to dismantle plough groove type pipe joint

Technical field

The utility model relates to the pipe joint technical field, and what be specifically related to is a kind of plough groove type pipe joint of exempting to dismantle.

Background technique

Most fire-prevention pipes are to connect by flange on the existing market, and the speed that flange connects is slow, complex procedures, and destroy the zinc coat and the coating layer on pipe fitting surface easily; Simultaneously,, then need to use the joint welding of welding machine between flange and pipeline in order to guarantee the sealing of flange connections, the mode of this welding, both uneconomical, and have safety, pollution hidden trouble;

For this reason, people have developed groove type clip pipe joint, this groove type clip pipe joint is made up of two semicircle arcuation clip spares, rubber gasket and fastening pieces, though this structure has solved dangerous, the pollution hidden trouble problem of bringing with the flange connecting pipeline, still there is following shortcoming in it:

As shown in Figure 3, if during connecting pipeline, the screw that then will unload earlier on the lower catch hoop takes out the interior seal washer 7 of clip spare, coat lubricant oil at seal ring and the pipe fitting end that processes groove then, then seal washer 7 is inserted on the pipeline, again two semicircle arcuation clip spares are pieced together, be fastened on the pipe fitting.This structure operation is got up very inconvenient, and the bad control in position, if the seal ring position is not installed in the center of two pipeline grooved surfaces, leaks easily.

Summary of the invention

The purpose of this utility model provides a kind of groove type quick coupling of exempting to dismantle, and this model utility structure has quick mounting when connecting pipeline spare, exempts from dismounting, safety, reliable, vibration isolation, good seal performance and characteristics easy to maintenance.

The utility model is achieved through the following technical solutions: exempt to dismantle the groove type quick coupling, be made up of split type clip, round rubber seal ring, nut and bolt;

The split type clip is the member that is put together by two arc arch parts, this split type clip is an ellipticity, the inner peripheral wall of described split type clip is provided with a circle seal ring mounting groove, and is symmetrically arranged with two lugs on the perisporium of the outer ring of split type clip; Lug is to be used for construction bolt.

The round rubber seal ring adopts high-quality rubber to make, has good self lubricity, the inner ring peripheral wall of round rubber seal ring is provided with two circle grooves, the cross section that promptly constitutes this round rubber seal ring is the unique design of figure of three shape, and its circular diameter of crosspiece rubber ring between the two circle grooves is less than the port bore of this round rubber seal ring; The round rubber seal ring is to be contained in the mounting groove of split type clip inwall;

Advantage of the present utility model is: when utilizing the utility model connecting pipeline, its round rubber seal ring can make the joint area of the connecting pipeline of two-way be contained in the middle fully, play the effect of snubber, more help the sealing that pipeline connects, and quick for installation, do not need to dismantle split type clip and round rubber seal ring, only need directly two pipe fitting butt joints to be inserted in the round rubber seal ring, simple to operate, high working efficiency and favorable sealing property.

Fig. 2 is the round rubber seal ring schematic cross-section in the utility model structure;

Fig. 3 is the seal washer schematic cross-section in the existing conventional construction;

Fig. 4 is for exempting to dismantle the linkage structure schematic representation between plough groove type pipe joint and the pipeline in the utility model.

Embodiment

As shown in Figure 1, exempt to dismantle the groove type quick coupling, form by split type clip 2, round rubber seal ring 1, nut 3 and bolt 4;

As shown in Figure 1, split type clip 2 is the members that are put together by two arc arch parts (5,6), this split type clip 2 is an ellipticity, the inner peripheral wall of described split type clip 2 is provided with a circle seal ring mounting groove 21, and is symmetrically arranged with two lugs (51,61) on the perisporium of the outer ring of split type clip 2; Bolt 4 is to be used for fastening two arcs arch part (5,6) by two lugs (51,61);

As shown in Figure 2, round rubber seal ring 1 adopts high-quality rubber to make, has good self lubricity, the inner ring peripheral wall of round rubber seal ring 1 is provided with two circle grooves (11,12), the cross section that promptly constitutes this round rubber seal ring 1 is the unique design of figure of three shape, and crosspiece rubber ring 13 its circular diameters between the two circle grooves (11,12) are less than the port bore 14 of this round rubber seal ring 1; Round rubber seal ring 1 is to be contained in the mounting groove 21 of split type clip 2 inwalls;

As shown in Figure 4, before installation exempts to dismantle plough groove type pipe joint, on the flat mouthful of end connector outer surface wall of two pipe fitting A and B, be processed into a groove A-1 and a B-1 at first respectively, promptly form a joint area A-2 and a B-2 at flat mouthful of end place of two pipe fittings, respectively the joint area A-2 of two pipe fittings and B-2 are inserted in two circle grooves (11 of round rubber seal ring 1,12), i.e. two pipe fitting A and B butt joint this moment, because two circle grooves (11,12) crosspiece rubber ring 13 its circular diameters between are less than the diameter of pipe fitting A and B, the partition that crosspiece rubber ring 13 is therefore arranged when two pipe fitting A and B butt joint, and joint area A-2 and B-2 just in time are in the centre of seal ring 1, nut 3 is fastening must be tight more, then connect closely more between two pipe fitting A and the B, its sealability is fabulous;

As need change wherein pipe fitting A or during B, only need unscrew nut 3, the pipe fitting that directly will need to change is extracted and is got final product.

The utility model exempts to dismantle the groove type quick coupling, no matter be to install or retubing, do not need to make with lubricator with dismounting clip 2 or with round rubber seal ring 1 and in clip 2, take out, thereby reach the purpose of quick mounting, improved working efficiency greatly.

Above mode of execution only is used to the technical solution of the utility model is described and is unrestricted, as the technical solution of the utility model being made amendment or being equal to replacement, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
