Abstract

The utility model provides a water leakage-proof joint. The utility model is characterized in that a plurality of reverse buckles are shaped at the front end of at least one pipe jointing mouth of the joint, the upper end of each reverse buckle forms a round table shape and the lower end is a connecting segment of which the outer diameter is smaller than that of the round table at the upper end. The utility model solves the problem of water leakage. The utility model adopts the technical scheme so that the joint can be conveniently used and maintained by users, saves operation cost and water resources and does not increase production cost.

Description

The leakproof water swivel

Technical field

The utility model relates to used joint in family expenses, the commercial processing equipment, and specifically being meant can guard tube and the joint that leaks of joint joint, and this joint also can be applied among the processing equipment of fluids such as oil, gas, is used for the connection of pipeline.

Background technique

Over nearly more than 20 years, the application of water-treating equipment has been the whole nationization, the popularizing of globalization.But but exist the problem that joint leaks.As shown in Figure 1, straight-through, bend pipe, threeway and decussate texture are arranged is four kinds of four-ways etc. to existing joint structure.With first kind of structure is example, specifies the reason that existing joint leaks.As shown in Figure 2, be water pipe 2 ' connect and joint 1 ' and by a nut 3 ' locking, this structure is under the state of work, have hydraulic pressure or air pressure, mobile material (specifically referring to water here) is arranged by this joint, because pressure can not be invariable, understanding butt joint like this has very strong impact, the phenomenon of vibration, i.e. water hammer can often appear in joint.Time one is long, and becoming flexible can appear in the structure of locking, so just removes the phenomenon of now leaking easily.

There is the waste to water in existing joint, such saving that is unfavorable for water resources.For the user, the operation and maintenance inconvenience of getting up.For manufacturer, the problem of leaking also is a technological difficulties.Solved the problem of leaking, can the conserve water resource, also have good technical benefit, economic benefit.

The model utility content

In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is in that a kind of improved joint is provided, and after nut screwing clamping, the function of self-locking is arranged, and is in locked state, has good waterproof effect.

In order to achieve the above object, the utility model adopts following technological scheme, it is a kind of leakproof water swivel, it is characterized in that, the front end of taking over mouthful at least one of joint forms some back-offs, the upper end of described back-off is a frustoconic shape, and its lower end is a linkage section, and the external diameter of described linkage section is less than the external diameter of upper end round platform.

In order to reach better effect, the utility model also has:

To manage and insert when taking over mouth, the utility model also has a locking nut to be enclosed within on the joint, the radian of closing in is arranged, so that nut can lock-on connection and pipe at the place, internal thread bottom of this nut.

Described linkage section is a column, and described " post " shape is for having the curved surface of inclination along the upper end of back-off.

Described joint is for leading directly to threeway, bend pipe or geneva cross, convenient use under different situations.

After will managing the insertion joint, owing on interface tube, have with back-off, and back-off is a volume platform shape, one end is big, one end is little, and the usefulness of the pipe of rising is arranged, and has guaranteed that at first this locking nut of degree of fiting of pipe and joint is enclosed within on the pipe, the closing in radian is arranged in nut, be stuck in the back-off place, form self-locking, can not occur becoming flexible, the phenomenon that can occur leaking not, thus the problem of leaking solved.Use the novel above-mentioned technological scheme that adopted, the user makes things convenient for operation and maintenance, has reduced user cost, and the conserve water resource does not increase cost of production, helps promoting.Can produce good technical benefit, social benefit.

Specifically execute mode

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is done detailed description and interpretation.Embodiment is the description and interpretation detailed to the utility model, is not to qualification of the present utility model.

Shown in Fig. 3,4, an embodiment of the present utility model provides a kind of leakproof water swivel, present embodiment is a free flow coupling 1, front end at the adapter mouth 11 of joint 1 has a back-off 111, the upper end of described back-off 111 is a frustoconic shape 1111, its lower end is a linkage section 1112, and linkage section is a column, and described " post " its outer surface is for having the curved surface of inclination along the upper end of back-off.And the external diameter of described linkage section 1112 forms "T"-shaped back-off less than the external diameter of upper end round platform 1111.

As shown in Figure 9, there is the radian of closing at the place, internal thread bottom that tightens nut 3, so that nut can lock-on connection 1 and pipe 2.As shown in Figure 5, will manage 2 and insert the adapter mouth at 11 o'clock, locking nut 3 is enclosed within on the joint 1, and the radian of closing in is arranged at the place, internal thread bottom of this nut 3, so that nut can lock-on connection 1 and pipe 2.Insert the place, bottom that takes over mouth 11 when pipe 2, owing to take over the round platform that mouthful 11 front ends have a back-off 111, make pipe 2 be in the state of the pipe that rises, the while also has the part of a linkage section 1112, this Duan Weiyi cylindricality below round platform, cut the external diameter of its outside dimension less than round platform, form a back-off, pipe 2 can be pinned, have auto-lock function, the locking of locking nut 3 is arranged in addition, to reach anti-effect of leaking.

As shown in Figure 6, be another embodiment, the utility model discloses a kind of leakproof water swivel, be specially tee union.

As shown in Figure 7, be the 3rd embodiment of the present utility model, a kind of leakproof water swivel is provided, be specially elbow.

As shown in Figure 8, be the 3rd embodiment of the present utility model, a kind of leakproof water swivel is provided, be specially geneva cross.

Above joint structure, can use under different situations for pipeline, the utility model utilization is fallen mouthful and the design of the pipe that rises, and reaches anti-purpose of leaking, the utility model does not destroy the basic structure of existing joint, can be used as the upgrading products of existing joint, the user makes things convenient for operation and maintenance, has reduced user cost, the conserve water resource, do not increase cost of production, help promoting, can produce good technical benefit, social benefit.

In addition, the utility model also can be applied among the processing equipment of fluids such as oil, gas except used joint in the processing equipment that relates to family expenses, commercialization, is used for the connection of pipeline.
