Description

Technical Field

[0001] The utility model relates to the technical field of valve control, and more specifically, to a valve opening and closing control device for a ground well valve. Background Art

[0002] Sewage treatment systems are equipped with numerous valves, categorized by the medium being transported, including water valves, mud valves, and gas valves. They are also classified by their installation location, either above-ground or underground. When installing valves, the operating handwheel should generally be level with your chest, typically 1.2 meters from the operating floor. Floor-mounted valves should have their handwheel facing upward for ease of operation. However, some valves are located in inaccessible locations, such as those in the air or in underground wells, making direct operation difficult.

[0003] In order to solve the problem of controlling valves that are difficult to directly access, a variety of technical means have been adopted, such as an existing valve opening and closing device, which includes a hand-held part, a connecting part and a clamping part; the hand-held part includes a handwheel, a forward and reverse motor fixedly arranged on the handwheel and a support tube, one end of the support tube is fixed to the middle of the lower surface of the handwheel, and the other end faces the connecting part; the connecting part includes an obliquely arranged inclined rod, a universal joint and a vertically arranged vertical pipe; the upper end of the oblique rod passes through the center of the support tube and is connected to the rotating shaft of the forward and reverse motor, the oblique rod is connected to the inside of the support tube through a bearing, the lower end of the oblique rod is connected to the upper end of the vertical pipe through a universal joint, and the lower end of the vertical pipe faces the clamping part; the clamping part includes a turntable and a plurality of clamping rods; the lower end of the vertical pipe is fixedly connected to the middle of the upper end surface of the turntable. This solution can control valves that are inconvenient to directly contact. However, when using the device to control valves in a well, due to the limited space in the well, the complicated pipeline laying and the installation of multiple valves, it is difficult to ensure the stability of the hand-held part and the connection part when the clamping part is rotated, and it is easy to interfere with other valves or pipelines in the well, which not only affects the operating efficiency but also easily damages the device. Utility Model Content

[0004] The purpose of the present utility model is to overcome the shortcomings of the prior art in that when a valve in an underground well is remotely controlled, the device is difficult to maintain stability and is prone to interference with other valves or pipelines in the underground well. A valve opening and closing control device for an underground well valve is provided. The device in this solution can keep the device stable during the process of remotely controlling the underground well valve, and can avoid interference between the device and other valves or pipelines in the underground well.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A valve opening and closing control device for a ground well valve is provided, comprising a handwheel, a valve stem, a coupling and a clamping portion connected in sequence, wherein the clamping portion can be clamped with the valve handwheel, and further comprising a shell and a clamping assembly, wherein the valve stem is located in the inner cavity of the shell and is rotatably connected to the shell, and the clamping assembly comprises a supporting portion and a clamping portion, wherein one end of the supporting portion is mounted on the outer surface of the shell, and the other end is connected to the clamping portion, and the clamping portion can clamp the side wall of the edge of the ground wellhead.

[0007] When the control device of the present invention is working, the operator first changes the angle between the clamping part and the valve stem through the coupling, then holds the housing and extends the clamping part into the ground well until the clamping part is clamped with the valve handwheel on the valve in the ground well and the clamping part is clamped on the side wall of the ground well mouth. At this time, the handwheel is rotated, and the rotation of the handwheel drives the valve stem to rotate in the housing. The rotation of the valve stem drives the coupling to rotate. The rotation of the coupling drives the clamping part to rotate. The rotation of the clamping part drives the valve handwheel clamped with the clamping part to rotate. The rotation of the valve handwheel completes the control of the valve in the ground well.

[0008] The valve opening and closing control device in the utility model can fix the shell at the underground wellhead by setting the clamping component, thereby keeping the device stable and avoiding interference with other valves or pipelines in the underground well during operation.

[0009] Furthermore, the clamping portion is a C-shaped clamp, the inner cavity of which is used to clamp the sidewall of the wellhead edge. A locking bolt is also provided on the sidewall of the clamping portion, which is threadedly connected to the clamping portion and extends into the inner cavity of the clamping portion. The C-shaped clamp clamps the sidewall of the wellhead edge, which can be snapped into the inner cavity of the C-shaped clamp, providing a simple and convenient clamping method. The locking bolt firmly secures the sidewall of the wellhead edge within the C-shaped clamp, further improving the stability of the clamping.

[0010] Furthermore, the housing is also provided with a sliding portion, which is slidably connected to the housing, and the support portion is connected to the sliding portion. The sliding portion is also provided with a locking portion that secures the sliding portion to the housing. The support portion is mounted to the outer surface of the housing via the sliding portion. The sliding portion can slide on the housing, thereby driving the support portion to slide on the housing. This allows adjustment of the position of the support portion on the housing, i.e., the length of the housing extending into the well, allowing the device to control valves in more locations within the well. The locking portion can be a positioning bolt on the sliding portion. When the positioning bolt is rotated until it is tightly fitted with the outer surface of the housing, it prevents the sliding portion from sliding on the housing.

[0011] Furthermore, the support portion includes a first support rod, a second support rod, a third support rod, a fourth support rod, a connecting seat, an adjustment seat, and a lead screw, wherein the connecting seat is rotatably connected to one end of the lead screw, the adjustment seat is threadedly connected to the lead screw, one end of the first support rod is rotatably connected to the clamping portion, and the other end is rotatably connected to the adjustment seat; one end of the second support rod is rotatably connected to the clamping portion, and the other end is rotatably connected to the connecting seat; one end of the third support rod is rotatably connected to the sliding portion, and the other end is rotatably connected to the adjustment seat; one end of the fourth support rod is rotatably connected to the sliding portion, and the other end is rotatably connected to the connecting seat, the axis of the first support rod is parallel to the axis of the fourth support rod; and the axis of the second support rod is parallel to the axis of the third support rod. The first, second, third, and fourth support rods form a parallelogram, and when adjusting the length of the support rod, the position of the adjustment seat on the lead screw is changed by rotating the lead screw, thereby changing the angle between the first and second support rods, thereby completing the adjustment of the length of the support rod. The supporting part of the folding support has a better supporting effect and is more convenient to adjust. The supporting part can also be a telescopic rod or other length-adjustable structure.

[0012] Furthermore, the clamping assemblies are provided in a plurality, equidistantly arranged circumferentially on the sliding portion with the axis of the valve stem as the center. Having multiple clamping assemblies can further increase the clamping strength against the sidewall of the wellhead, improving the stability of the device. Generally, two clamping assemblies are provided, ensuring stability while also preventing obstruction of the wellhead.

[0013] Furthermore, a lighting unit is installed on the housing, and the distance between the lighting unit and the coupling is smaller than the distance between the sliding unit and the coupling. The lighting unit is installed on the housing through a base, and the base can be rotatably connected to the housing, and the lighting unit can be rotated on the base. After the lighting unit is installed, the environment inside the well can be illuminated by the lighting unit, so that the operator can understand the well environment more directly and smoothly clamp the clamping unit on the valve handwheel. The lighting unit can be a flashlight or other portable light-emitting device. The base can be rotated on the housing, and the lighting unit can be rotated on the base, so that the lighting direction of the lighting unit can be adjusted, which makes it easier for the operator to accurately observe the situation inside the well.

[0014] Furthermore, bearings are installed at both ends of the inner cavity of the housing, and the valve stem is sleeved on and fixedly connected to the inner ring of the bearings. The bearings reduce friction between the valve stem and the housing when the valve stem rotates, thereby preventing the friction generated by the valve stem from damaging the housing.

[0015] Furthermore, the coupling is a three-section universal coupling. The three-section universal coupling has a larger rotatable angle, so that the clamping portion can clamp the valve handwheel at more angles.

[0016] Furthermore, the clamping portion includes a rotating disk and a clamping rod. The rotating disk is connected to the coupling. The rotating disk is provided with a plurality of mounting holes, which are equidistantly arranged around the rotating disk's midpoint. The clamping rod is threadedly connected to the mounting holes. The plurality of mounting holes on the rotating disk allows an appropriate number of clamping rods to be installed in the mounting holes according to the shape of the valve handwheel, thereby making the clamping portion adaptable to various valve handwheel shapes.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a valve opening and closing control device for an underground well valve, which can fix the outer shell at the underground well mouth by setting a clamping component, thereby keeping the device stable and avoiding interference with other valves or pipelines in the underground well during operation.

[0019] The valve opening and closing control device of the utility model can adjust the position of the support rod on the outer shell through the arrangement of the sliding part, so that the device can control valves at more positions in the well.

[0020] The valve opening and closing control device of the utility model enables an operator to more directly understand the underground well environment through the provision of the lighting part, and smoothly clamp the clamping part on the valve handwheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Specifically, there are two clamping assemblies, and the two clamping assemblies are arranged in a mirror image on the sliding portion 4 with the axis of the valve stem 2 as the center.

[0040] The beneficial effects of this embodiment are as follows:

[0041] The side wall of the wellhead edge is clamped by a C-shaped clamp, and the side wall of the wellhead edge can be snapped into the inner cavity of the C-shaped clamp, which is a simple and convenient clamping method. The side wall of the wellhead edge can also be firmly fixed in the C-shaped clamp by a locking bolt 601, further improving the stability of the clamping. The support part 5 is installed on the outer surface of the shell 3 through the sliding part 4.
