Description

Pressure test blanking plug

Technical Field

The utility model relates to a pressure testing blanking plug technical field especially relates to a pressure testing blanking plug.

Background

In the process of petroleum, natural gas and geological exploration drilling, in order to reach the preset drilling depth, drill bits with different specifications and diameters need to be adopted for segmented drilling, each time the specification of the drill bit is changed, a sleeve is put to perform sealing operation, and then a pressure test blanking plug is used for checking the sealing effect of the sleeve. When the pressure testing blanking plug is used for carrying out pressure testing operation, the pressure testing blanking plug is only needed to be put into the lower part of the pipe or the blowout preventer, which needs to test pressure, so that the pressure testing can be carried out, the use is very simple, convenient and reliable, and the blanking plug is recycled for next use after the pressure testing is finished.

But current pressure testing blanking plug external structure is comparatively simple, and the blanking plug outside lacks the mechanism that supports to blockking up rubber to influence the stability of blockking up the mechanism.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the prior art in the pressure testing blanking plug exterior structure comparatively simple, the blanking plug outside lacks the problem of carrying out supporting mechanism to blockking up rubber, and the pressure testing blanking plug that provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a pressure testing blanking plug, is including being responsible for the body and connector, the connector is with being responsible for the top fixed connection of the body, it is equipped with the external screw thread to surround on the outer wall of connector, it is equipped with the internal thread to surround on the inner wall of connector, the fixed rubber sleeve that has cup jointed in top of being responsible for the body.

Preferably, a limiting sleeve is fixedly sleeved on the outer wall of the bottom of the main pipe body.

Preferably, both sides of the rubber sleeve are provided with fixed sleeves, and the fixed sleeves are fixedly sleeved outside the main pipe body.

Preferably, a sealing ring is fixedly inserted into the inner bottom of the connector.

Preferably, a plurality of baffles are fixedly connected to the bottom of the outer wall of the connector, and the inner walls of the baffles abut against the outer wall of the rubber sleeve.

Preferably, a plurality of clamping blocks are fixedly connected to the outer wall of the main pipe body, and clamping grooves corresponding to the clamping blocks are formed in the inner wall of the rubber sleeve.

Has the advantages that:

1. the connecting position of the main pipe body can be effectively limited by the arrangement of the limiting sleeve, the arrangement of the fixing sleeve can effectively prevent the up-and-down movement of the rubber sleeve, and the arrangement of the baffle can also effectively prevent the shaking of the rubber sleeve;

2. the setting of sealing washer can guarantee the sealed effect of connection of connector position department, and the setting of fixture block can be injectd the position of rubber sleeve simultaneously, the utility model discloses in support stop gear's setting through many places, can guarantee the stability of blanking plug rubber sleeve to the stability in use of blanking plug has been guaranteed.
