CN204831689U - Universal pressure tapping - Google Patents

Abstract

The utility model provides an universal pressure tapping, including top connection and lower clutch, be equipped with the external screw thread on the surface of wherein top connection, the longitudinal section of lower clutch appears for T, it still includes the union, and the union includes two upper and lower companies cavity hooped columns bodies as an organic whole, that the internal diameter is different, above wherein the inner wall of a cavity hooped column body be equipped with with the external screw thread assorted internal thread of top connection, now the internal diameter of a cavity hooped column body be less than the lower clutch upper portion, and be greater than the lower part of lower clutch for the union can block the T shape position of lower clutch. Through utilizing the union, can adopt union and top connection to be connected again after the orientation is adjusted to upper and lower joint, only the rotatory union of needs can, can not influence the position of top connection to the feasible orientation that can rotate the pressure panel wantonly.

Description

Universal pressure gauge connector

technical field

The utility model relates to the field of pressure gauge structures, in particular to a universal pressure gauge joint.

Background technique

Oilfield oil pipelines, water pipelines, and gas pipelines are all installed on the main line with pressure pipes, and a valve is installed at the other end of the pressure pipe. Turn on the metric connector.

Since there are three threaded connections between the main line and the pressure gauge's British joint, and the starting angles of the threaded threads at each connection are different, which eventually leads to different orientations of the pressure gauge panel. When installing the pressure gauge, it often happens that when the screw thread of the pressure gauge is rotated to the dead point, the panel orientation of the pressure gauge cannot be horizontal or vertical to the pipeline, resulting in the phenomenon that the orientation of each pressure gauge cannot be unified.

Utility model content

The technical problem to be solved by the utility model is: to provide a universal pressure gauge joint, which can rotate the orientation of the pressure panel arbitrarily.

The technical solution adopted by the utility model to solve the above technical problems is: a universal pressure gauge joint, which is characterized in that it includes an upper joint and a lower joint, wherein the outer surface of the upper joint is provided with external threads, and the outer surface of the lower joint is The longitudinal section is T-shaped; it also includes a live joint, which consists of two hollow ring cylinders connected together up and down with different inner diameters. The inner thread of the hollow ring cylinder below is smaller than the upper part of the lower joint and larger than the lower part of the lower joint, so that the movable joint can block the T-shaped part of the lower joint.

According to the above solution, a sealing gasket is also provided between the upper and lower joints.

The beneficial effects of the utility model are:

1. By using the joint, the joint can be connected to the upper joint after the upper joint and the lower joint are adjusted in direction. Only the joint needs to be rotated, and the position of the upper joint will not be affected, so that the position of the pressure panel can be rotated arbitrarily towards.

2. By adding a sealing gasket between the upper and lower joints, the tightness of the joints is ensured.

Detailed ways

Below in conjunction with specific example and accompanying drawing, the utility model is further described.

As shown in Figures 1-4, this embodiment provides a universal pressure gauge joint, including an upper joint 1 and a lower joint 3, wherein the outer surface of the upper joint 2 is provided with external threads, and the longitudinal section of the lower joint 3 is T-shaped; it also includes a live joint 4, the live joint 4 includes two upper and lower hollow ring cylinders connected together with different inner diameters, wherein the inner wall of the upper hollow ring cylinder is provided with a thread that matches the outer thread of the upper joint Internal thread, the inner diameter of a hollow ring cylinder below is smaller than the upper part of the lower joint, and greater than the bottom of the lower joint, so that the movable joint can block the T-shaped part of the lower joint 3.

Preferably, a sealing gasket 2 is also provided between the upper and lower joints.

When installing, first put the union through the lower end of the lower joint 3, then contact the upper joint 1, the sealing gasket 2 and the lower joint 3 in sequence, and finally use the joint 4 to rotate so that the internal thread of the joint 4 and the inner thread of the upper joint 1 The external thread is connected, and the lower joint 3 can also be turned to fine-tune the orientation during the process.
