Abstract

A combined tee joint is characterized in that threads are machined on the inner hole wall of a flange joint of a tee joint-shaped main body (shown in figure 1), and a union joint or a hoop joint can be connected through the threads. The utility model discloses simple structure, convenient to use, reliable operation for during the well head manifold of oil field borehole operation connects, can be according to the construction equipment needs of difference, change into the mode of multiple connections such as flange, union or clamp wantonly through the combination, thereby bring the convenience for field operation.

Description

A kind of combined type threeway

Technical field: the utility model relates to a kind of mining site construction equipment, especially for a kind of combined type threeway of oilfield downhole operation construction.

Background technology: before the utility model; Each oil field is in the wellhead manifold of underground work such as gas well completion test or oil-well strata transformation connects; The common special three-way joint of many employings; Therefore to be equipped with the tee junction of multiple connected modes such as flange, the oil ninth of the ten Heavenly Stems or clip according to different construction equipments, make troubles to execute-in-place.

Summary of the invention: the purpose of the utility model is: for the wellhead manifold of oilfield downhole operation connects a kind of combined type threeway is provided; Because this device can be according to different construction equipment needs; Change into flange, multiple ways of connecting such as the oil ninth of the ten Heavenly Stems or clip arbitrarily through making up, thereby bring convenience to execute-in-place.

The purpose of the utility model realizes through following measure: a kind of combined type threeway is that the main body by the threeway shape constitutes, and the joint of main body is the flange that has steel ring slot, it is characterized in that on the flanged ends inner hole wall of main body, being processed with screw thread.

The purpose of the utility model can also realize through following measure: the flanged ends of main body can be through be threaded oil joint in the ninth of the ten Heavenly Stems or the thimble connector on the inner hole wall.

The utility model is simple in structure, easy to use, reliable operation; The wellhead manifold that is used for oilfield downhole operation connects; Can be according to different construction equipment needs, through making up multiple ways of connecting such as changing into flange, the oil ninth of the ten Heavenly Stems or clip arbitrarily, thereby bring convenience to execute-in-place.

Description of drawings: Fig. 1 is the structural representation of combined type threeway, and Fig. 2 is the structural representation of oil joint in the ninth of the ten Heavenly Stems, and Fig. 3 is the structural representation of thimble connector.

The specific embodiment: the combined type threeway is to be made up of the main body of threeway shape (Fig. 1), and the joint of main body (Fig. 1) is the flange that has steel ring slot, on the flanged ends inner hole wall of main body (Fig. 1), also is processed with screw thread; The flanged ends of main body (Fig. 1) can be through be threaded oil joint in the ninth of the ten Heavenly Stems (Fig. 2) or the thimble connector (Fig. 3) on the inner hole wall.

The operating principle of combined type threeway with method for using is: but in the wellhead manifold of oilfield downhole operation is connected the construction equipment needs, the flange that has steel ring slot on the main body (Fig. 1) through the threeway shape directly is connected with the flange of steel ring structure or the flange of rubber cushion structure; Also can be connected with joints such as the oil ninth of the ten Heavenly Stems or clips again through be threaded oil joint in the ninth of the ten Heavenly Stems (Fig. 2) or the thimble connector (Fig. 3) on its flanged ends inner hole wall; Also can be connected with other kinds joint through the screw thread on its flanged ends inner hole wall.Because this device can adapt to multiple connected mode through after making up, thereby need not to be equipped with the tee junction of multiple connected mode in underground work the time, thereby bring convenience to execute-in-place.

Claims
