[0002] A pipe sealer (also called a pipe sealer head) is a commonly used device in oil and gas development. It is used to seal wellheads or pipelines to prevent oil and gas leakage or control the flow of oil and gas.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figures 1-5As shown, an embodiment of the utility model proposes a pipe sealer for oil production. The pipe sealer for oil production designed in this scheme can improve the sealing effect of oil and gas switch pipelines, is suitable for the sealing of pipelines of various sizes, and improves the use effect. It includes a pipe cover 1, a sealing member 2 is connected to the pipe cover 1, an adjusting member 3 is rotatably connected to the pipe cover 1, and four resistance members 4 are arranged in a ring array on the pipe cover 1. The resistance member 4 is connected to the driving member 5, and the driving member 5 is connected to the adjusting member 3. When sealing the oil and gas development pipeline, one end of the cavity 103 of the pipe cover 1 is sleeved on the port of the pipeline, and then the adjusting member 3 is rotated and adjusted. By kneading and rotating the rotating ring 302, the convex ring 304 will rotate in the rotating ring. The movable groove 102 is limited and rotated, and the adjusting ring 301 is driven at this time. The tooth groove 303 set on the inner wall of the adjusting ring 301 is kneaded and connected with the gear 503. Therefore, when the adjusting ring 301 rotates, the four gears 503 set on the outer wall of the pipe cover 1 rotate at the same time. The gear 503 is fixedly connected to the screw rod 501, so the screw rod 501 will rotate between the two rotating seats 502, and the cross block 504 threadedly connected on the screw rod 501 is slidably connected in the limiting sliding groove 402 opened on the adjusting frame 401. When the cross block 504 slides and adjusts on the screw rod 501, it will make the adjusting frame 401 slide and adjust in the sliding groove 105. Since the adjusting frame 401 is fixedly connected to the inclined block 403, and the inclined block 403 and the inclined surface entity part 104 are matched and conflicted, When the adjustment frame 401 is slidably adjusted, the inclined block 403 will slide and contact the inclined surface entity part 104. Since the inclined end of the inclined block 403 faces the pipe cover 1 at one end away from the threaded hole 101, and the inclined end of the inclined surface entity part 104 faces the pipe cover 1 at one end of the inclined surface entity part 104, when the inclined block 403 is slidably adjusted toward the top end of the slope of the inclined surface entity part 104, due to the contact between the inclined surface entity part 104 and the inclined block 403, the combined thickness of the inclined surface entity part 104 and the inclined block 403 will be increased. When the four inclined blocks 403 arranged in the annular array are adjusted at the same time, the combined diameter of the four inclined blocks 403 will be reduced, so that the anti-slip pad 404 can be tightly contacted with the outer wall of the pipeline, and the sleeve of the pipe cover 1 on the pipeline can make the anti-slip The pad 404 is tightly against the outer wall of the pipeline. At this time, pulling the pipe cover 1 toward the port of the pipeline will make the inclined surface solid part 104 contact the inclined block 403, further increasing the contact force of the inclined block 403 against the outer wall of the pipeline, thereby ensuring a tight connection effect. When the adjustment frame 401 slides inside the sliding groove 105, when the inclined block 403 slides toward the end away from the threaded hole 101, the length of the adjustment frame 401 leaking out from the outer wall of the pipe cover 1 is reduced. At this time, the cross block 504 on the inner wall of the limiting sliding groove 402 can be raised and lowered on the adjustment frame 401 to ensure that the cross block 504 can always be connected with the thread of the screw rod 501. When the pipe cover 1 is firmly fixed at the port of the pipeline, the screw rod 202 can be rotated by turning the knob 201.The screw 202 is threadedly adjusted within the threaded hole 101, capable of controlling the sliding adjustment of the pressing disc 205 inside the cavity 103, enabling the sealing gasket 206 to tightly abut against the port part of the pipeline, achieving the use of sealing the pipeline, improving the sealing effect of the pipeline. Through the cooperative design, it can avoid the problem of incomplete pipeline sealing and resulting oil and gas leakage. Moreover, through the design, it can be applied to seal pipelines of various sizes, improving the usage effect.

The design of the pipe cover 1 satisfies the overall connection of the device, ensuring the sleeving use at the end part of the oil and gas switch pipeline.

[0026] As Figure 3 shown, in some embodiments, the plugging member 2 is composed of a knob 201, a screw 202, a rotating head 203, a rotating hole 204, a pressing disc 205 and a sealing gasket 206.
