Description
Technical field
The utility model belongs to the connection area of pipe joint, especially a kind of pipe joint utilizing water depth pressure to complete product pressure compensation.
Background technique
The existing connecting pipeline of product under water joint mainly plays a part to connect, seal and transmission medium in pipeline at present, and connecting pipeline joint will bear very high submergence pressure in severe deepwater work environment, and change along with the difference of operating water depth, also can be subject to the impact of billow and undercurrent in various degree.Because connecting pipeline joint internal pressure can not realize compensating the autobalance of external pressure, can not realize mating with extraneous job behavior in a big way, continuing to increase sealing effect and can be deteriorated gradually along with operating depth, even can cause final leak case, and then cause tremendous economic to lose.
Therefore, remain the working performance that flood deep water lower seal pipe joint is good, the internal pressure how balancing flood deep water lower seal pipe joint just seems particularly important to realize reliable sealing.System architecture will ensure that flood deep water lower seal pipe joint is compact on the one hand, reduces connector exterior configuration, reduces the possibility that large depth of water lower seal pipe joint breaks down; To guarantee that large depth of water lower seal pipe joint can adapt to different operating depths on the other hand, avoid the accident causing pipeline because of the excessive infiltration of hydraulic pressure.
Model utility content
In order to solve the problem that current pipe joint sealing effect is deteriorated with operating depth increasing sealing effect, the purpose of this utility model is that providing a kind of utilizes operating depth pressure to complete pressure compensation and then improve the pipe joint of sealing effect, along with the darker sealing effect of operating depth is better, there is advantage simple and quick, that highly versatile, manufacture difficulty are low and applied widely.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flood deep water downforce compensating type sealing pipeline connector, comprise nut and crimp head, the stage casing column part of crimp head is provided with the pressure compensation holes be in communication with the outside, the seal groove UNICOM of above-mentioned pressure compensation holes and crimp head end face, ○-shaped seal ring is placed in the seal groove of crimp head end face, communicates bottom ○-shaped seal ring with operating depth aqueous medium.
Further, according to the difference of the operating depth of pipeline, coordinate with seal ring by opening different pressure compensation bore dia, quantity and blowing angle in relevant position.
Further, 3-8 pressure compensation holes circumference is evenly distributed on the stage casing cylindrical wall of crimp head, and pressure compensation holes blowing angle coordinates with seal ring.
Further, crimp head end face is also provided with pressure transducer, and pressure transducer is connected to obtain pipe joint internal pressure with peripheral control unit.
Further, also comprise sealing screw, the one or more pressure compensation holes on the stage casing cylindrical wall of crimp head can carry out shutoff by sealing screw.
Further, also comprise sealing cover, the one or more pressure compensation holes on the stage casing cylindrical wall of crimp head can carry out shutoff by sealing cover.
The beneficial effects of the utility model are:
The utility model efficiently solves a difficult problem for sealing reliability in the various connection procedure of all-product line under water, only need do the reliable sealing that simple change both can complete all-product line under water on existing basis simultaneously, and along with the darker sealing effect of operating depth better, by increasing pressure compensation holes on joint, effectively can solve the dark line seal difficult problem of flood, there is the advantages such as simple and quick, highly versatile, manufacture difficulty are low and applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model crimp head;
Wherein: 1-crimp head, 2-pressure compensation holes, 3-standard O-ring seals, 4-nut.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, a kind of flood deep water downforce compensating type sealing pipeline connector, comprise nut 4 and crimp head 1, the stage casing column part of crimp head has the pressure compensation holes 2 be in communication with the outside, hole and seal groove UNICOM, according to the difference of the operating depth of pipeline, coordinate with seal ring 3 by opening different compensate opening diameter, quantity and blowing angle in relevant position, the underwater pipeline reliable sealing of respective water depth can be completed.○-shaped seal ring 3 is placed in the seal groove of crimp head end face, communicate with operating depth aqueous medium bottom ○-shaped seal ring in work, pressure when operating depth becomes large in Seal cage raises, the pressure of zero shape ring recess inner chamber also increases thereupon, thus make the gluing, sealing face that zero shape circle is tighter, compensate zero shape circle pressure distortion, so the darker sealing effect of the utility model seal operation depth of water is better.
In one embodiment, can arrange 3-8 pressure compensation holes 2 circumference is evenly distributed on the stage casing cylindrical wall of crimp head, pressure compensation holes 2 blowing angle coordinates with seal ring, thus can under the condition ensureing joint structure intensity, go for the larger hydraulic pressure operating mode of the large depth of water, multiple pressure compensation holes 2 is divided equally distribution and the structure of joint can be made more firm, can not have influence on the intensity of joint, the working life of extending connector.
In one embodiment, need the pressure in monitoring pipe pipeline connector to obtain hydraulic pressure data under some operating mode, also pressure transducer can be provided with at crimp head end face, pressure transducer is connected to obtain pipe joint internal pressure with peripheral control unit, this kind arranges and pipe joint can be made to work in suitable range hydraulic pressure and run, prevent pipeline and pipe joint due to hydraulic pressure excessive and burst.
In order to adapt to the different depth of water, water quality and water flow velocity, the quantity reducing pressure compensation holes 2 is needed under some operating mode, one or more pressure compensation holes on the stage casing cylindrical wall of crimp head can carry out shutoff by sealing screw or sealing cover, to expand the operating mode accommodation of joint.
According to principle of the present utility model, pipe joint operating depth pressure completes pressure compensation, and then improve underwater pipeline joint sealing effect, can be widely used in various all-product line under water and connect, the pipeline be particularly useful under large depth of water environment connects seal operation.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristics, utilize technology contents that the utility model discloses to make local change or modify Equivalent embodiments, and do not depart from technical characteristics content of the present utility model, all still belong to the utility model technical characteristics scope.
