[0002] Underground pipelines, often used in chemical and thermal power plants, often require valves that require adjustment by creating wells to allow for valve assembly, allowing for flow control. Existing technology typically involves staff descending into the wells to adjust these valves. This poses a safety hazard due to the depth of the wells, often exceeding two meters, and the presence of hazardous gases. Furthermore, according to security regulations, this work requires prior application for a confined space work permit, making the process cumbersome. Currently, no solution is available to address these issues. Utility Model Content

[0005] An adjusting rod is centrally provided at the lower portion of the twist handle. The adjusting rod is in the form of a splined sleeve, comprising an inner sleeve and an outer sleeve, and a positioning member is provided on the outer sleeve; thereby, the inner and outer sleeves are prevented from rotating.

[0006] The end of the regulating rod is provided with a valve recognition component, and the valve recognition component is provided with a valve constraint body.

[0007] The effect achieved in this way is that the regulating rod is adjusted to an appropriate length, lowered into the well, and put on the valve through the valve recognition component, and then the regulating rod is controlled to make the valve fit into the constraint body, and then the handle is turned to realize the opening and closing of the valve or flux adjustment.

[0008] The beneficial effects of the present invention are as follows: the present invention solves the problems of inconvenient downhole valve adjustment and high operation risk in the prior art, and realizes flexible adjustment of downhole valves without going down into the well. In particular, the equipment solves the problem of inconvenience in valve adjustment mechanism claiming valves caused by the well depth, and the equipment has a simple structure, low cost, no maintenance, and is easy to disassemble and store, and has great safety promotion value.

[0016] The realization, functional characteristics and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0017] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 For an underground valve opening and closing device described in the present utility model, it includes a rotating handle 1, and the rotating handle 1 is a gripping member of the device;

[0018] An adjusting rod 2 is centrally arranged at the lower part of the rotating handle 1. The adjusting rod 2 is in the form of a spline sleeve, including an inner sleeve and an outer sleeve, and a positioning member 3 is arranged on the outer sleeve; the effect achieved thereby is to prevent rotation between the inner and outer sleeves;

[0019] A valve claiming member 4 is arranged at the end of the adjusting rod 2, and a valve restraint body 5 is arranged on the valve claiming member 4.

[0020] The effect achieved thereby is that the adjusting rod 2 is adjusted to an appropriate length, lowered into the well, sleeved on the valve through the valve claiming member 4, then the adjusting rod 2 is controlled to sleeve the valve into the restraint body, and then rotating the rotating handle 1 can achieve the opening and closing or flux adjustment of the valve.

[0021] Embodiment 1, referring to the accompanying drawings of the specification Figure 1 and Figure 2 The valve claiming member 4 is in the form of a flared mask, that is, a frustum of a cone form with a hollow interior;

[0022] The described valve restraint body 5 is a plurality of connecting rods, and the valve restraint body 5 is uniformly arranged in an array on the inner cavity of the valve claiming member 4.

[0023] Preferably, at least three valve restraint bodies 5 are provided, and they are arranged in a central array on the inner cavity of the valve claiming member 4 in a ring shape.

[0024] The effect achieved thereby is that the above arrangement form corresponds to a valve in the form of a handwheel; that is, a plurality of valve restraint bodies 5 in the form of connecting rods are inserted into the gaps between the handwheels, and the rotation of the valve is adjusted by rotating the turning handle 1.

[0025] Also, since the depth of the pipe shaft often exceeds two meters, it is difficult to claim the valve directly by inserting the valve restraint member into the gap between the valves. However, the bellmouth-shaped mask converges from bottom to top, which can assist the valve restraint body 5 to quickly claim the valve.

[0026] Embodiment 2, referring to the attached drawings of the specification Figure 3 And Figure 4 , the valve claiming member 4 is in the form of a plate body, and a claiming notch is milled on its bottom surface. The claiming notch gradually converges from one side of the bottom surface of the plate body to the other side, and its tail end is in the form of a rectangular notch. The rectangular notch is the valve restraint body 5.

[0027] Preferably, the adjusting rod 2 is arranged on one side of the valve claiming member 4, at the connection section between the rectangular notch and the claiming notch.

[0028] The effect achieved thereby is that the above arrangement form corresponds to a wrench-type valve. That is, due to the relatively deep pipe shaft, the relatively wide claiming notch is sleeved on the valve, and then the device is translated so that the valve wrench gradually enters the rectangular notch to position and restrain the wrench. In this case, rotating the turning handle 1 can achieve valve adjustment.

[0029] Embodiment 3, referring to the attached drawings of the specification Figure 5 , a spline through groove 11 is provided in the center of the turning handle 1, and the spline through groove 11 is closely attached to the adjusting rod 2;

[0030] One end of the outer sleeve and the inner sleeve are respectively provided with a limiting member;

[0031] The valve claiming member 4 is threadedly connected to the adjusting rod 2.

[0032] Preferably, the limiting member is arranged in the following form: a limiting washer is arranged inside the outer sleeve, and a limiting retaining ring is integrally connected to the outside of the end of the inner sleeve. The effect achieved thereby is to prevent the complete separation between the inner and outer sleeves during operation; and when separation is required, the inner sleeve is slid to the other side where the limiting washer is provided, and the separation between the inner and outer sleeves can be achieved.

[0033] The effects achieved thereby are that the device is convenient to disassemble and assemble and convenient to store.

[0034] Furthermore, the positioning member 3 is a hard limit bolt or a spring pin.

[0035] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
