Abstract
The utility model discloses a pipe joint used for various pipes connecting, which is composed of a washer and a joint shell. Wherein, the diameter of the end of the joint shell is larger than that of the shell body of the joint shell, and is formed an outer convex recessed cavity; a grasp ring, the washer and an O shape sealing ring are arranged in the recessed cavity sequentially from the inner to the outer side. The utility model overcomes the weakness of the present pipe joint, such as difficult in installation, easy rusting, and poor performance of hygiene and sealing, which is a pipe joint with simple structure, stable sealing performance, convenient operation, long service life and low cost.
Description
The utility model relates to a kind of link, especially a kind of pipe coupling that is used for various pipelines connections.
Shortcomings such as everyone knows, present being used to carried the pipe coupling of liquid to have difficulty is installed, easily gets rusty, health and poor sealing performance, needs to twine in the joint additional materials such as the rope made of hemp or raw meal belt during connecting tube, and cost cost height, working life are short.
The purpose of this utility model provides a kind of simple in structure, sealability is reliable, easy to use, life-span long, the cost cost is low pipe coupling, and it has overcome the shortcoming that present pipe coupling exists.
The purpose of this utility model is achieved in that it is made up of packing ring and joint shell, the bore of described joint shell end forms the cavity of an evagination greater than the diameter of joint shell body, and cavity is equipped with promptly ring, packing ring and " O " shape seal ring from inside to outside successively.
Described promptly ring is one " V " shape annulus; That described joint shell can manufacture is two logical, threeway and four-way; The metal tube outer surface that connects in the described joint shell is provided with and promptly encircles corresponding groove; Described cavity can be cast as one with the body of joint shell, also can be by being threaded to one; It is the raw material manufacturing that described joint shell can adopt stainless steel or copper; Described promptly ring and packing ring adopt the stainless steel material manufacturing.
Advantages such as said structure has that sealability is reliable, easy to use because the utility model has adopted, the life-span is long, the cost cost is low, sanitation performance good and pollution-free.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that pipe coupling of the present utility model connects plastic tube;
Fig. 3 is the structural representation that pipe coupling of the present utility model connects metal tube.
Among the figure: 1. promptly encircle; 2. packing ring; 3. " O " shape seal ring; 4. joint shell; 5. cavity; 6. groove.
Thereby the bore of joint shell 4 ends forms the cavity 5 of an evagination during manufacturing greater than the diameter of joint shell 4 bodies, the inside of cavity 5 is equipped with successively from inside to outside and promptly encircles 1, packing ring 2 and " O " shape seal ring 3, promptly encircling 1 is one " V " shape annulus, it and rounded washers 2 adopts the stainless steel material with elasticity and good toughness, 3 of " O " shape seal rings can adopt sanitation performance good, can heatproof again can be withstand voltage the quality seal material.It is the raw material manufacturing that joint shell 4 can adopt stainless steel or copper, can have so not that scaling, sanitation performance are good, pollution-free, long service life, cost is low and advantage such as attractive in appearance.Pipe coupling of the present utility model can directly be inserted pipeline in the joint during use, and easy to use, one is slotting promptly available, promptly encircle 1 owing to being provided with in the inboard, end of pipe coupling, institute is so that pipeline connects and need not cut with scissors tooth, and one inserts and can use, but and pressurized from motive sealing.
Pipe coupling of the present utility model can engage easily with the composite pipe that commercially available plastic tube or top layer are plastics, and one inserts promptly available (as shown in Figure 2).When pipe coupling and commercially available metal tube (being composite pipe of thin-wall metal etc. as thin-wall stainless steel, thin-wall copper pipe, external layer) when being connected, need metal tube outer surface size car one groove 6 in accordance with regulations with promptly encircle 1 and cooperate, will remove the burr of the mouth of pipe this moment, being inserted into pipe coupling makes and promptly encircles 1 dop and snap in the groove 6, cause is promptly encircled 1 dop in pipe coupling, so can make when the tube head of metal tube enters pipe coupling and promptly encircle 1 dop and snap in smoothly in the groove 6, can not withdraw from (as shown in Figure 3) easily in case snap in but.Pipe coupling of the present utility model can manufacture two pass joints, tee union and cross fitting as required, and the cavity 5 of pipe coupling end can be cast as one with the body of joint shell 4, also can be by being threaded to one; Pipe coupling of the present utility model can be applicable to the usefulness of the health water supply conveyance conduit connection used in the industries such as dwelling house, building, medical treatment, pharmacy and food processing.
