Abstract
Description
Technical Field
[0001] This utility model relates to the field of gate valve technology, and in particular to a drilling high-pressure gate valve with a handle locking mechanism. Background Technology
[0002] A high-pressure gate valve is a control device for controlling the flow of fluid in a pipeline. Operators typically rotate the valve stem by using the handle at the top, which in turn drives the gate plate up and down through the valve stem thread, thereby achieving the purpose of connecting, cutting off, and regulating the flow rate, and flexibly adjusting the flow of fluid in the pipeline.
[0003] However, with existing high-pressure gate valves, it is difficult to restrict the position of the valve stem after the operator has turned it clockwise or counterclockwise. In actual use, due to the length of the handle, it is easy to accidentally touch the handle, which will affect the opening or closing state of the gate.
[0004] To address this issue, we designed a drilling high-pressure gate valve with a handle locking mechanism. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a drilling high-pressure gate valve with a handle locking mechanism. After the operation is completed, the handle is positioned by positioning the central tube, thereby avoiding the situation where the handle is accidentally touched.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A drilling high-pressure gate valve with a handle locking mechanism includes: an outer tube, a casing, a central tube, and a positioning element;
[0008] The lower end of the outer tube is connected to a pipe; multiple first positioning teeth and multiple positioning grooves are respectively provided at the middle part and the lower end of the outer tube. The upper end of the first positioning tooth is shorter than the lower end, and the positioning groove is an inverted "U" shape.
[0009] The upper end of the sleeve is provided with a plurality of second positioning teeth and guides. The lower end of the second positioning teeth is triangular, and the top surface of the guides is provided with triangular grooves corresponding to the lower ends of the plurality of second positioning teeth.
[0010] A spring is provided at the lower end of the central tube and is nested inside the sleeve. The middle part of the central tube is a rectangular section. Multiple transmission rods one and multiple transmission rods two are provided on the outer wall of the central tube. The transmission rod one is located between two second positioning teeth, and the multiple transmission rods two are initially located above multiple positioning grooves.
[0011] The positioning component includes: a slider, a protrusion, a third positioning tooth, and a limiting plate. The slider is nested on the central tube and is located in a rectangular segment. A protrusion is provided on the slider. Multiple third positioning teeth are provided at the lower end of the slider, and the limiting plate surrounds the middle of the multiple third positioning teeth.
[0012] In one embodiment, flanges are connected to both ends of the pipe, and the pipe is installed through the flanges.
[0013] In one embodiment, the lower end of the sleeve extends into the pipeline, and a gate is provided at the lower end of the sleeve for closing the pipeline.
[0014] In one embodiment, an outer tube extends from the upper end of the central tube, and a handle is provided at the upper end of the central tube.
[0015] In one embodiment, the end of the protrusion is provided with a spring piece, which is located between the upper ends of the two first positioning teeth. When the central tube rotates, the slider rotates synchronously. The spring piece is blocked by multiple upper teeth and thus bends and deforms. The purpose is to determine the rotation angle of the central tube by the jolt provided by the spring piece to the central tube, so that the protrusion can be accurately inserted between the two lower teeth.
[0016] In one embodiment, a protective cover is provided on the pipe, the protective cover being connected to the pipe by a plurality of screws, and the protective cover covering the handle.
[0017] In one embodiment, the end face of the transmission rod is rounded, and the rounded end of the transmission rod is located between the two second positioning teeth, which facilitates the movement of the transmission rod between the two second positioning teeth and between the guide and the second positioning teeth.
[0018] In one embodiment, the protruding corner at the lower end of the second positioning tooth is rounded, which is beneficial for guiding the transmission rod to move upward.
[0019] The beneficial effects of this utility model are as follows:
[0020] (1) After the gate opens or closes the pipeline, the handle is pressed down and the handle rebounds upward through the spring, so that the transmission rod moves to the two second positioning teeth on one side. Simultaneously, the transmission rod engages into the positioning groove, thereby positioning the central tube through the outer tube and positioning the sleeve through the central tube, that is, positioning the handle to prevent accidental contact with the handle, thereby affecting the opening or closing state of the gate.
[0021] (2) After controlling the flow rate and adjusting the opening and closing distance of the gate, this utility model has multiple positioning grooves and second positioning teeth. Through the meshing of multiple transmission rods one and two with multiple positioning grooves and second positioning teeth, the handle can be locked at multiple angles. Attached Figure Description

Detailed Implementation
[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0031] Please see Figure 1-2 This utility model provides a drilling high-pressure gate valve with a handle locking mechanism, including: an outer tube 1, a casing 2, a central tube 3, and a positioning component 4;
[0032] Please see Figure 1-3 The outer tube 1 is vertically arranged, and the lower end of the outer tube 1 is connected to the pipe 10. The two ends of the pipe 10 are respectively connected to the flange 11. The outer tube 1 is provided with a sleeve 2, a central tube 3, and a positioning component 4.
[0033] Please see Figure 2-4The outer tube 1 is provided with a first positioning tooth 12 at the middle part and a positioning groove 13 at the upper end of the outer tube 1. There are multiple first positioning teeth 12 and positioning grooves 13. Multiple first positioning teeth 12 and positioning grooves 13 are equidistantly arranged on the inner wall of the outer tube 1 along the axis of the outer tube 1. The first positioning tooth 12 is divided into an upper tooth 121 and a lower tooth 122 in the vertical direction. The length of the upper tooth 121 is less than that of the lower tooth 122. The positioning groove 13 is an inverted "U" shape.
[0034] Please see Figure 2-3 The lower end of the sleeve 2 extends into the pipe 10. A gate 21 is provided at the lower end of the sleeve 2. The gate 21 is used to close the pipe 10. The upper end of the sleeve 2 is provided with a second positioning tooth 22 and a guide 23. There are multiple second positioning teeth 22. The multiple second positioning teeth 22 are equidistantly arranged on the inner wall of the sleeve 2 along the axis of the sleeve 2. The lower end of the second positioning tooth 22 is triangular. The guide 23 is located below the multiple second positioning teeth 22. The top surface of the guide 23 is provided with multiple triangular grooves corresponding to the lower ends of the multiple second positioning teeth 22.
[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The lower end of the central tube 3 is nested inside the sleeve 2. A spring 32 is provided at the lower end of the central tube 3 to support the central tube 3. An outer tube 1 extends from the upper end of the central tube 3. A handle 31 is provided at the upper end of the central tube 3. The middle part of the central tube 3 is a rectangular section 30. Multiple transmission rods 34 and 35 are provided on the outer wall of the central tube 3. The multiple transmission rods 34 and 35 are equidistant from the axis of the central tube 3. The multiple transmission rods 34 are initially located at the upper end between the multiple second positioning teeth 22. When the handle 31 is rotated, the sleeve 2 is rotated synchronously through the multiple transmission rods 34 and the multiple second positioning teeth 22, thereby actuating the gate 21 to open the pipe 10. The multiple transmission rods 35 are initially located above the multiple positioning grooves 13 to avoid obstructing the rotation of the central tube 3.
[0036] Please see Figure 2 , Figure 3 , Figure 6The positioning component 4 includes: a slider 41, a protrusion 42, a spring piece 43, a third positioning tooth 44, and a limiting plate 45. The slider 41 is nested on the central tube 3. The slider 41 is initially positioned on the rectangular segment 30 of the central tube 3 by the support of the second spring 33. The opposite ends of the slider 41 are respectively provided with protrusions 42, and the ends of the two protrusions 42 are respectively provided with spring pieces 43. The spring pieces 43 are located between two adjacent first positioning teeth 12. After the central tube 3 drives the slider 41 to move downward, the protrusions 42 are located between two adjacent lower teeth 122, thereby positioning the slider 41. When the central tube 3 rotates, the slider 41 rotates synchronously. The two spring pieces 43 are blocked by multiple upper teeth 121 and thus bend and deform. The purpose is to determine the rotation angle of the central tube 3 by using the tactile feedback provided by the spring plate 43 to the central tube 3, so that the protrusion 42 can be accurately inserted between two adjacent lower teeth 122. There are multiple third positioning teeth 44, which are equidistantly arranged at the lower end of the slider 41 along the axis of the slider 41. The middle part of the multiple third positioning teeth 44 surrounds the limiting plate 45. After the slider 41 moves downward, the multiple third positioning teeth 44 engage with the multiple second positioning teeth 22. The limiting plate 45 abuts against the top surface of the multiple second positioning teeth 22 to limit the maximum descent distance of the slider 41. When the central tube 3 further descends, the slider 41 moves out of the rectangular segment 30, so that when the central tube 3 rotates, the slider 41 no longer rotates synchronously.
[0037] Preferably, the pipe 10 is provided with a protective cover, which is connected to the pipe 10 by a plurality of screws and covers the handle 31.
[0038] Preferably, the end face of the transmission rod 34 is rounded, and the end of the transmission rod 34 is located between the two second positioning teeth 22, which facilitates the movement of the transmission rod 34 between the two second positioning teeth 22 and between the guide 23 and the second positioning teeth 22.
[0039] Preferably, the lower end of the second positioning tooth 22 has a rounded corner, which is beneficial for guiding the transmission rod 34 to move upward.
[0040] Working principle of this utility model:
[0041] When opening or closing pipe 10, the operator rotates handle 31, and sleeve 2 rotates synchronously. Gate 21 opens or closes pipe 10. Then, handle 31 is pressed down, and central shaft tube 3 moves downward. Simultaneously, positioning component 4 moves downward, positioning protrusion 42 between two adjacent lower teeth 122. Multiple third positioning teeth 44 engage with multiple second positioning teeth 22. This pre-positioning of sleeve 2 prevents transmission rod 34 from abutting the triangular slope of guide component 23 when descending, causing sleeve 2 to rotate and trigger gate 21. Central shaft tube 3 descends further, and limiting plate 45 abuts against the top surface of multiple second positioning teeth 22, causing slider 41 to move out of rectangular segment 30. Figure 7 As shown, transmission rod 34 descends along the gap between the two second positioning teeth 22, passing through the channel formed by the triangular slope of the guide 23 and the lower end of the second positioning teeth 22. When the central shaft tube 3 rebounds upward by spring 32, this channel guides transmission rod 34 to move to one side between the two second positioning teeth 22. Simultaneously, transmission rod 35 moves downward along the two positioning grooves 13, and then transmission rod 35 rises and engages in the positioning groove 13, thereby positioning the central shaft tube 3 through the outer tube 1, positioning the sleeve 2 through the central shaft tube 3, that is, positioning the handle 31, preventing accidental contact with the handle 31, thereby affecting the opening or closing state of the gate 21.
[0042] To control the flow rate and adjust the opening and closing distance of the gate 21, since there are multiple positioning grooves 13 and second positioning teeth 22, the handle 31 can also be locked at multiple angles through the above actions.
[0043] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
