Description
Technical Field
The utility model relates to a tooling equipment technical field specifically is a seal test frock.
Background
For a polished rod four-way pipe joint without threaded connection, the joint needs to be sealed during a sealing test, and for a general threaded joint, only a corresponding ball head or a corresponding outer sleeve nut needs to be sealed. The tool structure used in the existing sealing test is complex in structure, inconvenient to assemble and disassemble, difficult to operate in the sealing process, low in operation efficiency due to limitation of structural characteristics of parts, poor in sealing performance and low in reliability. Therefore, a sealing test tool is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a seal test frock to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a seal test frock, includes the polished rod four-way pipe, the polished rod four-way pipe includes four the same branch pipes, the branch pipe side is provided with the joint, the cover is equipped with the lantern ring on the branch pipe, lantern ring outside fixedly connected with overcoat nut, the internal thread has been seted up to the overcoat nut inboard, U type groove has been seted up to the overcoat nut, the side that connects is provided with the connecting block, the connecting block middle part is provided with the end cap, the connecting block side is provided with the go-between, the outside of go-between is provided with.
Preferably, the joint is a joint with spherical shape on the side surface.
Preferably, the diameter of the plug is slightly smaller than the inner diameter of the branch pipe, and a sealing gasket is arranged on the outer side of the plug.
Preferably, the branch pipe and the joint are of an integrally formed structure.
Compared with the prior art, the beneficial effects of the utility model are that: this kind of seal test frock, structural design is simple reasonable, has stronger practicality, through cut out U type groove on the overcoat nut, be convenient for with the nut card on the branch pipe work piece, can take off it fast after seal test finishes, the purpose of quick dismantlement installation has been reached, through setting up internal thread and external screw thread structure, can lock go-between and overcoat nut, the end cap is inserted and is established inside the branch pipe, sealed effect has been strengthened, the end cap is provided with sealed the pad with the junction of branch pipe, the sealed effect of frock has further been strengthened, frock processing is simple, and high operability, can effectively improve test efficiency, the reliability is greatly promoted, has good innovation effect.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a sealed experimental frock, includes polished rod four-way pipe 1, its characterized in that: polished rod four-way pipe 1 includes four the same branch pipes 11, 11 sides of branch pipe are provided with and connect 12, branch pipe 11 and joint 12 are the integrated into one piece structure, connect 12 and be the joint of spherical shape for the side, the cover is equipped with the lantern ring on the branch pipe 11, lantern ring outside fixedly connected with overcoat nut 13, overcoat nut 13 inboard is seted up there is internal thread 14, overcoat nut 13 has seted up U type groove, and U type groove forms through machine cutting process, through cutting out U type groove on overcoat nut 13, is convenient for with the nut card on 11 work pieces of branch pipe, can take off it fast after seal test, has reached the inconvenient purpose of quick dismantlement installation, has avoided the problem of nut dismouting.
The side that connects 12 is provided with connecting block 15, connecting block 15 middle part is provided with end cap 16, end cap 16's diameter slightly is less than branch pipe 11 internal diameter, and the end cap 16 outside is provided with sealed the pad, connecting block 15 side is provided with go-between 17, the outside of go-between 17 is provided with external screw thread 18, through setting up internal thread 14 and external screw thread 18 structure, can lock go-between 17 and cap nut 13, and end cap 16 inserts and establishes inside branch pipe 11, has strengthened sealed effect, and end cap 16 is provided with sealed the pad with the junction of branch pipe 11, has further strengthened the sealed effect of frock, and frock processing is simple, and maneuverability is strong, can effectively improve test efficiency, has greatly promoted the reliability, has good innovation effect.
The working principle is as follows:
this kind of seal test frock, structural design is suitable, when carrying out the seal test, at first embolia branch pipe 11 with outer nut 13 along the U type groove that the cutting is good, is connected connecting block 15 through internal thread 14 and external screw thread 18 and outer nut 13 to screw both, later end cap 16 insert branch pipe 11 inside with the laminating of branch pipe 11 inner wall, the sphere that connects 12 pastes really with the curved surface of connecting block 15 side, thereby realizes the sealing process of frock.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
