Description

Technical Field

[0001] The utility model relates to the field of pipeline pressure testing, in particular to a finished product pressure testing head. Background Art

[0002] In order to facilitate the pressure test of newly built pipelines and the nitrogen replacement of in-service pipelines during the first-level hot work, the finished pressure test head is designed to fully guarantee the safety of on-site pressure test and hot work connection. At the same time, the finished pressure test head can effectively save on-site construction time nodes and reduce the main pipeline opening welding construction and penetration test. Existing pressure test pipelines all use a separate head to seal the pipeline. Due to the high-pressure closed environment inside the pipeline, the head may be ejected by the high-pressure gas and the sealing is not tight. Utility Model Content

[0003] In order to solve the technical problem that existing pressure test pipelines all use a separate head to seal the pipeline, and the head may be ejected by high-pressure gas due to the high-pressure closed environment inside the pipeline, resulting in a loose seal, the utility model provides a finished pressure test head.

[0004] The utility model adopts the following technical scheme to achieve: a finished pressure test head, including a pressure test head body, characterized in that the interior of the pressure test head body includes an adapter, the outside of the adapter is connected to a connecting pipe, the top of the adapter is connected to an adapter tube, a pressure gauge is installed above the adapter tube, and a head mechanism is installed on the outside of the adapter, and the head mechanism includes:

[0005] A mounting block, wherein the mounting block is mounted at both ends of the head mechanism;

[0006] A closing head, the closing head is fixedly mounted on the inner side of the mounting block; the closing head has a diameter that matches the size of the connecting pipe, and the closing head blocks the connecting pipe;

[0007] A fixing rod, the fixing rod is connected to the inner side of the mounting block, the fixing rod passes through the mounting block, and the fixing bolt fixes the mounting block and the fixing rod;

[0008] A fixing bolt is used to connect the mounting block to the fixing rod.

[0009] When it is necessary to seal the pipeline, the staff holds the sealing mechanism, aligns the closing head on the sealing mechanism with the connecting pipe, and simultaneously inserts the closing heads at both ends of the sealing mechanism into the interior of the connecting pipe, thereby sealing and blocking the connecting pipes at both ends.

[0010] As a further improvement of the above solution, the head sealing mechanism is provided with two groups of fixing rods installed in an opposite manner, and the two groups of fixing rods are connected by a fixing mechanism, and the fixing mechanism fixes the two groups of fixing rods.

[0011] As a further improvement of the above solution, the fixing mechanism includes:

[0012] A fixing sleeve, the fixing sleeve is in a semicircular ring shape and sleeved on the outer surface of the fixing rod;

[0013] A movable ring buckle is connected between the two groups of fixed sleeves.

[0014] A fixed hanging ear, which is installed at the bottom end of the fixed sleeve and is in the shape of a straight plate;

[0015] A tightening and tightening rotary block is connected to the two groups of the fixing ears.

[0016] The staff turns the tensioning knob, which starts to rotate and then fixes the fixed ear. The fixed sleeve rotates with the movable ring buckle as the base point, and the two relatively fixed sleeves fix and engage the connection of the fixed rod, locking the connection of the two fixed rods. Since the connection of the fixed rod is locked, the head mechanism closed at both ends of the connecting pipe constitutes a whole. High pressure on one end of the connecting pipe cannot break open the closing head, making the closure more stable, avoiding the problem that the existing pressure test pipeline uses a single head to seal the pipeline. Due to the high-pressure closed environment inside the pipeline, the head may be ejected by the high-pressure gas, resulting in a loose closure.

[0017] Compared with the prior art, the beneficial effect of the utility model is that the utility model fixes and engages the connection of the fixed rod through two relative sets of fixing sleeves, and locks the connection of the two sets of fixing rods. Since the connection of the fixing rods is locked, the head mechanism sealed at both ends of the connecting pipe constitutes a whole. High pressure on the connecting pipe at one end alone cannot break open the closing head, making the closure more stable, avoiding the problem that the existing pressure test pipelines all use a single head to seal the pipeline. Due to the high-pressure closed environment inside the pipeline, the head may be ejected by the high-pressure gas, resulting in a loose closure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Embodiment 1:

[0025] Please combine Figure 1-Figure 3 This embodiment proposes a finished pressure test head, including a pressure test head body 1, the pressure test head body 1 includes an adapter 2 inside, the outside of the adapter 2 is connected to a connecting pipe 21, the top of the adapter 2 is connected to a transfer tube 3, the top of the transfer tube 3 is installed with a pressure gauge 4, the outside of the adapter 2 is installed with a head mechanism 5, the head mechanism 5 includes:

[0026] Mounting blocks 51, which are mounted at both ends of the end capping mechanism 5;

[0027] The closing head 52 is fixedly mounted on the inner side of the mounting block 51; the diameter of the closing head 52 matches the size of the connecting pipe 21, and the closing head 52 blocks the connecting pipe 21; when the pipeline needs to be capped, the staff holds the capping mechanism 5, aligns the closing head 52 on the capping mechanism 5 with the connecting pipe 21, and simultaneously inserts the closing heads 52 at both ends of the capping mechanism 5 into the interior of the connecting pipe 21, so that the closing heads 52 at both ends seal and block the connecting pipes 21 at both ends;

[0028] A fixing rod 53, the fixing rod 53 is connected to the inner side of the mounting block 51; the fixing rod 53 passes through the mounting block 51, and a fixing bolt 54 fixes the mounting block 51 and the fixing rod 53;

[0029] The fixing bolt 54 connects the mounting block 51 and the fixing rod 53 .

[0030] The sealing mechanism 5 is provided with two groups of fixing rods 53 which are installed opposite to each other. The two groups of fixing rods 53 are connected by a fixing mechanism 55 , and the fixing mechanism 55 fixes the two groups of fixing rods 53 .

[0031] The fixing mechanism 55 comprises:

[0032] A fixing sleeve 551, which is in a semicircular ring shape and sleeved on the outer surface of the fixing rod 53;

[0033] The movable ring buckle 552 is connected between the two sets of fixing sleeves 551 .

[0034] A fixed hanging ear 553, which is installed at the bottom end of the fixed sleeve 551, and the fixed hanging ear 553 is in a straight plate shape;

[0035] The tightening and loosening rotating block 554 is connected to the two sets of fixing ears 553 .

[0036] The staff adjusts the position of the fixing rod 53 by turning the fixing bolt 54 to ensure that the two sets of fixing rods 53 are in the right position and the top ends are abutted together. After the two sets of fixing rods 53 are abutted together, the fixing mechanism 55 is sleeved on the connection of the two sets of fixing rods 53. The staff turns the loosening screw block 554, and the loosening screw block 554 immediately starts to rotate, and the loosening screw block 554 then fixes the fixing hanger 553, and the fixing sleeve 551 thereby rotates with the movable ring buckle 552 as the base point, and the two sets of fixing sleeves 551 relative to each other thereby fix the connection of the fixing rod 53 and lock the connection of the two sets of fixing rods 53. Since the connection of the fixing rod 53 is locked, the head mechanism 5 closed at both ends of the connecting pipe 21 constitutes a whole. High pressure on the connecting pipe 21 at one end cannot flush out the closing head 52, making the sealing more stable, avoiding the problem that the existing pressure test pipeline uses a single head to seal the pipeline. Due to the high-pressure sealing environment inside the pipeline, the head may be ejected by the high-pressure gas and the sealing is not tight.

[0037] The specific implementation steps of this utility model are as follows:

[0038] When it is necessary to seal the pipeline, the staff holds the sealing mechanism 5, aligns the closing head 52 on the sealing mechanism 5 with the connecting pipe 21, and simultaneously inserts the closing heads 52 at both ends of the sealing mechanism 5 into the interior of the connecting pipe 21. The closing heads 52 at both ends seal and block the connecting pipes 21 at both ends. As the closing heads 52 are inserted into the interior of the connecting pipe 21 for sealing, the fixing rods 53 also move relatively synchronously. The staff adjusts the position of the fixing rods 53 by turning the fixing bolts 54, so as to ensure that the two groups of fixing rods 53 are properly positioned and the top ends abut against each other. After the two groups of fixing rods 53 abut against each other, the fixing mechanism 55 is sleeved on the connection between the two groups of fixing rods 53. The staff turns the loosening and tightening knob 554 to loosen the knob. 554 then starts to rotate, and the tightening block 554 then fixes the fixed hanging ear 553, and the fixed sleeve 551 rotates with the movable ring buckle 552 as the base point, and the two relatively fixed sleeves 551 fix the connection of the fixed rod 53 to lock the connection of the two sets of fixed rods 53. Since the connection of the fixed rod 53 is locked, the head mechanism 5 closed at both ends of the connecting pipe 21 constitutes a whole. High pressure at one end of the connecting pipe 21 cannot break open the closing head 52, making the closure more stable, avoiding the problem that the existing pressure test pipelines all use a single head to seal the pipeline. Due to the high-pressure closed environment inside the pipeline, the head may be ejected by the high-pressure gas, resulting in a loose closure.

[0039] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
