Abstract

The utility model relates to a quick-acting connector for pipe which is used for the connection of various low-voltage water pipes of middle and small diameters or water-heating pipelines. The quick-acting connector for pipe adopts a metal structure which is disclosed in the specification. The quick-acting connector for pipe is composed of a connector body (1), two pipe screw caps (2) and two O-shaped rubber sealing rings (3); two water pipe end heads (4) which need to be connected are respectively inserted into the quick-acting connector for pipe from both sides of a pipe connector before the sealing rings are not pressed tightly; the seam of two water pipes is approximately positioned on the middle position of the connector body (1); connection is completed by tightly screwing the two pipe screw caps, and the two connected water pipe end heads (4) do not need tapping; the water pipe end heads (4) do not need to be rotated during installation. The utility model is convenient to disassemble and assemble, and installing workload is reduced.

Description

Quick-acting connector for pipe

The utility model is used for the connection of various low pressure medium-small diameter water pipes or plumbing pipe, also can be applicable to the connection of other fluid pipes.

Medium-small diameter low pressure water pipe or hot water pipe road connect most pipe thread metal joints that use.The water pipe termination that connects must artificial go out screw thread, when connecting with pipe screw joint, need on the pipe end screw thread, twine flax silk, seal grease is filled in brushing, need to turn very long water pipe with pipe wrench, time-consuming, effort, the processing tube screw thread must have special device, and major part is the manpower tapping, and the occupied ground area is big, water pipe termination screw thread is in transportation, damage easily in the loading and unloading, labor intensity is big in the installation, will change in mounted grid system particularly that wherein one section water pipe is very inconvenient, and pipe thread uses easy corrosion for a long time, whole water pipe all scrapped, caused wave useless.To connect the water pipe butt welding with two in aggregates though also have directly, and indispensable power supply in fabricating yard and electric welding equipment also must training electric welding skilled workers, and be very restricted.

The purpose of this utility model is that a kind of pipe joint that has improved metal and sealing rubber ring combination will be provided, and need not be processed with pipe thread on the water pipe termination that connects, and can reach mounting or dismounting fast, and is time saving and energy saving, convenient and reliable.

The purpose of this utility model is to realize like this, directly insert in the quick coupling of identical caliber specification two water pipe terminations that need to connect, seam approximately is in the neutral position of pipe joint, tighten the pipe nut that quick coupling has O type rubber ring then, making rubber seal compress distortion reaches sealing and bears fluid pressure in the water pipe, unclamp the pipe nut, quick coupling can slide along arbitrary water pipe in two water pipes, seam can show, and does not need to dismantle other pipelines in the pipe-line system.

The utility model is applicable to that the following various calibers of 2 English connect, and have the quick coupling of corresponding specification with it to different caliber designs.Though the quick pipe connecting header structure is more complicated slightly than the threaded metal joint structure of continuing to use, parts are convenient to the big batch centralized production in addition.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Figure one is the section of structure of a kind of quick coupling that the utility model proposes.

Below in conjunction with details and the working condition of figure one detailed description according to the concrete quick coupling that the utility model proposes.

Quick coupling comprises a metal connector body (1), two O type rubber seal (3) and two metal tube nuts (2) match, the inner conical surface that the processing of fittings body (1) both ends of the surface is at 45, O type rubber seal (2) is placed on the nut inboard near the fittings body two ends conical surface, will need the termination (4) of two water pipes connecting directly to insert from the both sides of quick water swivel before not compressing when seal ring.The butt joint of two water pipes (4) approximately is in the neutral position of fittings body.Tighten two nuts (2) then, be squeezed swelling distortion of rubber seal (3) is reliably promptly finished the installation that connects water pipe thereby reach sealing.

Claims

1, a kind of quick coupling is characterized in that by union body (1), manages nut (2) and two O type sealing rubber rings (3) composition for two, forms a load module, is applicable to that the low pressure of the following various calibers of 2 English inch connects.

2, union body according to claim 1 (1) is characterized in that the two ends outer round surface is processed with pipe thread, and both ends of the surface are processed with 45 ° inner conical surface.
