Description
Technical field
The utility model relates to underwater hydraulic quick coupling device, is specifically related to the tool joint pin of a kind of waterpipe hydraulic pressure.
Background technique
Underwater hydraulic rapid pipe joint is that one is equipped on subsea production system, a kind of equipment that extensive use and deep water hydrocarbon field are developed.Multiple underwater hydraulic rapid pipe joint is combined into Multifunctional quick joint, adds docking and locking mechanism, the quick connection that can realize many pipelines be separated.
The scheme that underwater hydraulic rapid pipe joint nearly all both at home and abroad at present adopts is a male and female head and a female joint collocation, one-way valve respectively containing a band push rod in tool joint pin and female joint, opened by the inner elements of check valve of push rod by both sides when docking, realize hydraulic path.
Because need to seal between tool joint pin and female joint before one-way valve opens, and in order to form hydraulic path, certain space must be left between one-way valve push rod and joint shell, therefore all there is a common problem in this kind of joint, namely after tool joint pin and female joint seal, a part of seawater can be left in joint inside, this part seawater can enter into hydraulic system along with hydraulic oil after the one-way valve opens on both sides, according to engineering experience, each plug enters the seawater amount of hydraulic system greatly about 3 ~ 5ml.Long-Time Service, the seawater entering into hydraulic system may remain in hydraulic pipe line, valve or hydraulic actuator, causes unnecessary corrosion, the stability of influential system and reliability.
Model utility content
The technical problems to be solved in the utility model is, overcomes deficiency of the prior art, provides the tool joint pin of a kind of waterpipe hydraulic pressure.
For technical solution problem, solution of the present utility model is:
The tool joint pin of a kind of waterpipe hydraulic pressure is provided, comprises step-like hollow joint, spool, housing, spiral spring and seal ring; Described seal ring comprises the first seal ring and the second seal ring, and described step-like hollow joint is nested in inside shell one end, and the joint between step-like hollow joint and housing is provided with the first seal ring; Described spool is arranged on inside the housing the other end, and wherein, the front-end face of described spool and the front-end face of housing are that the conical surface is fitted together to, and spool is nested in housing, and the chimeric place of the conical surface between spool with housing arranges the second seal ring and realizes sealing; The head of described spiral spring is connected with step-like hollow joint end, and this spiral spring extends and is arranged in the cavity of spool, and with the inner cavity wall close contact of spool.
In the utility model, described seal ring is round rubber circle.
In the utility model, described hull outside has been threaded connection locking nut.
In the utility model, described waterpipe hydraulic pressure tool joint pin entirety is in hollow structure, and its cross section is hollow circular ring.
Compared with prior art, the beneficial effects of the utility model are:
The utility model proposes the one-way valve structures using removable valve pocket, use the nonreturn valve core be hidden in valve pocket as the push rod opening hydraulic path, connect by mating between tool joint pin of the present utility model and corresponding female joint, the end face achieving docking mutually becomes plane, thus seawater or other environment liquids can be drained, realize the residual docking of no liquid.
Accompanying drawing explanation
Fig. 1 is tool joint pin structural representation of the present utility model.
Reference character in figure is: step-like hollow joint 1, first seal ring 2, housing 3, spiral spring 4, spool 5, locking nut 6, second seal ring 7.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, provide the specific embodiment of a kind of waterpipe hydraulic pressure tool joint pin, comprise step-like hollow joint 1, spool 5, housing 3, spiral spring 4 and seal ring (2,7);
Described seal ring comprises the first seal ring 2 and the second seal ring 7, and described step-like hollow joint 1 is nested in inside housing 3 one end, and the joint between step-like hollow joint 1 and housing 3 is provided with the first seal ring 2; Described spool 5 is arranged on inside housing 3 the other end, and wherein, the front-end face of described spool 5 and the front-end face of housing 3 are that the conical surface is fitted together to, and spool 5 is nested in housing 3, and the chimeric place of the conical surface between spool 5 with housing 3 arranges the second seal ring 7 and realizes sealing; The head of described spiral spring 4 is connected with step-like hollow joint 1 end, and this spiral spring 4 extends and is arranged in the cavity of spool 5, and with the inner cavity wall close contact of spool 5.
Wherein, described seal ring is round rubber circle.Locking nut 6 has been threaded connection outside described housing 3.Described waterpipe hydraulic pressure tool joint pin entirety is in hollow structure, and its cross section is hollow circular ring.
Spool 5 in the utility model embodiment is nonreturn valve core, use the one-way valve structures of this removable valve pocket, use the nonreturn valve core be hidden in valve pocket as the push rod opening hydraulic path, connect by mating between tool joint pin of the present utility model and corresponding female joint, the end face achieving docking mutually becomes plane, thus seawater or other environment liquids can be drained, realize the residual docking of no liquid.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.Such as seal ring can be the seal ring of other types; locking nut can use back-up ring or other modes to replace; all distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
