Abstract

The utility model discloses a joint for running water pipe, composed of sheaths, sealing rings and tope sleeves. The sheaths have the straight-way type, the bent pipe type, the three-purpose type and the size and diameter changed type. The end head parts of the sheaths are provided with taper holes, and the female threads matched with the top sleeve are arranged in the holes. When the running water pipes are connected, the sheaths, the sealing rings and the top sleeves are respectively sheathed on the external diameter of the water pipes and the joint of the two pipes. The sealing rings are positioned in the taper holes of the sheaths, then the top sleeves are screwed in the pipes to achieve the purpose of connecting the water pipes. The joint for running water pipe of the utility model doesn't require a wrench hinge wire spanner table, alleviates the labor intensity of the worker and improves the work efficiency when the pipe is arranged and maintained.

Description

Joint for running water pipe

The utility model relates to a kind of running water pipe joint.

As everyone knows, the head connection is abutted against in the connection of running water pipe.Joint has the straight tube style, the bend pipe style, and threeway style, CONCENTRIC REDUCER reducing style, its end is provided with the box thread for running water pipe termination screw-thread fit.This joint during piping erection, must could be connected with joint after the on-the-spot tapping in the termination of every water pipe, therefore, adopt this water pipe adapter to connect water pipe, labor strength is big, inefficiency, and be not easy to repair, so this water pipe adapter has improved necessity.

The purpose of this utility model provides a kind of running water pipe joint, and when using this joint to connect water water pipe, the water pipe termination need not tapping, has improved working efficiency, has alleviated labor intensity, and good airproof performance.

Below in conjunction with accompanying drawing the utility model is carried out detailed narration:

Fig. 1 is the utility model running water pipe joint schematic representation;

Fig. 2 is the schematic representation of the threeway style of Fig. 1 middle sleeve (1);

Fig. 3 is the schematic representation of the elbow style of Fig. 1 middle sleeve (1);

Fig. 4 is the schematic representation of the big or small reducing style of Fig. 1 middle sleeve (1).

Shown in accompanying

drawing

1,2,3,4, the utility model joint for running water pipe is to improve at existing joint to form, it is made of sleeve pipe (1), sealing ring (2), top cover (3), the version that its sleeve pipe (1) keeps existing water pipe head has through type, bent-tube boiler, three way type, concentric reducer reducing type, the termination that it is characterized in that sleeve pipe (1) all has bellmouth (4), be provided with the internal thread that cooperates with top cover (3) in hole (4), top cover (3) is circular cone screwed pipe with the level. When running water pipe connects, sleeve pipe (1) sealing ring (2) and top cover (3) are enclosed within respectively on the water pipe external diameter and two pipe joint places, sealing ring (2) is entered the bellmouth (4) of sleeve pipe with hand push, then taper top cover (3) is screwed in the sleeve pipe (1). Around the external diameter that under the effect of tapered top cover sealing ring (2) tightly is pressed in water pipe and pipe box. Top cover is twisted more tightly, and water pipe also just pushes more firmly, and sealing just better. When considering water pipe connecting tap standpipe, in order to strengthen the firmness of independent standpipe, can be pressed in water pipe external diameter and sealing ring contact position the groove of 1 millimeters deep with casing knife, make sealing ring fasten more firmly water pipe. The utility model bears hydraulic pressure 6.5kg/cm after tested²More than.

The utility model joint for running water pipe cover is compared with existing joint to have and is connected flexibly, and is easy to use, need not be with hinge filament plate work bench when the installation and maintenance pipeline, alleviated labour intensity, improved operating efficiency.
