Large-drift-diameter universal manifold pry adopting union connection

Abstract

The invention provides a large-drift-diameter universal manifold pry adopting union connection. The large-drift-diameter universal manifold pry comprises a movable elbow, a manifold and a base, wherein the movable elbow comprises a bent pipe and a union; the union is arranged on the outer side of the bent pipe in a sleeving mode; a clamping block is integrally formed on the outer side of the union; oblique openings are formed in the two sides of the union; an annular groove is formed in one end of the bent pipe; a lantern ring is welded to the other end of the bent pipe; a clamping pin is clamped on the union; and a clamping groove is formed in the outer side of the bent pipe. According to the large-drift-diameter universal manifold pry adopting union connection, the angle and length of the movable elbow can be adjusted, so that the connecting end of the movable elbow is quickly connected with other equipment, unscrewing and screwing operation of the union does not need to be conducted, and the adjusting efficiency of the movable elbow is improved; and the airtightness between the two bent pipes can be guaranteed through the lantern ring and the annular groove, high-pressure fluidis prevented from leaking outwards, safe work of the movable elbow is guaranteed, and the large-drift-diameter universal manifold pry is suitable for quick connection and use.

Description

[0002] Manifold skids are commonly used equipment in the process of oil and gas exploitation. The patent application number is CN201210196726.8 invention patent, which discloses the suction pile type underwater manifold skid structure. The existing manifold skid equipment basically has the advantages of firm installation, pipeline resistance The advantages of high pressure strength, long working hours, firm structure, and long service life can meet the requirements for the transportation of high-pressure fluids. However, for the existing manifold skid equipment, on the one hand, the manifold skid cannot be used according to The angle and distance can be flexibly adjusted according to the requirements of use, which makes it inconvenient for the joint of the manifold skid to quickly move to the desired position, and it is not convenient for quick positioning and connection. On the other hand, when the manifold skid is connected through the union, The union can be used to rotate and adjust the distance, but once the union is fixed, the manifold cannot be continuously rotated and adjusted, so that each adjustment of the manifold requires unscrewing and tightening of the union, which is not conducive to improving the adjustment of the manifold. On the other hand, when adjusting the manifold, it is easy to have a small gap between the pipes due to the rotation, which will cause the pipe connection to be loose, and in use, it will easily cause the high-pressure fluid to leak outward, which is not easy Conducive to ensuring the tightness of the pipeline
