Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a lockable regulating valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Existing regulating valves lack locking and limiting of rotation position, making it impossible to adaptively control and regulate according to actual use conditions, which is inconvenient to control.

[0003] For example, a multi-stage adjustable valve locking device disclosed in Chinese patent literature (publication number: CN217355791U) is simple in structure, convenient in adjustment, and greatly improves practicality. This is achieved by first connecting piece snapping onto the front outer side of the valve body, then splicing the second connecting piece with the first connecting piece, and then locking the locking bolt with a locking nut to install the connecting piece onto the valve body. After that, the limiting mechanism and the adjusting hole inside the adjusting plate are used to achieve multi-stage adjustment. The limiting rod is quickly inserted into the adjusting hole by the tension of the spring to limit the adjustment plate, thereby locking the position after the handle is turned.

[0004] However, in actual use, since the limiting mechanism is installed separately on the valve body through the second connector, the installation position needs to be repeatedly adjusted during installation to ensure the compatibility between the limiting rod and the adjusting hole, which is quite cumbersome. Furthermore, when adjusting the valve body, one hand needs to lift the lever and the other hand needs to turn the valve stem through the handle. In areas where valve bodies and pipelines are densely installed, this two-handed operation is inconvenient, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology. In actual use, since the limiting mechanism is installed separately on the valve body through the second connecting piece, the installation position needs to be repeatedly adjusted during installation to ensure the compatibility between the limiting rod and the adjusting hole, which is cumbersome. Furthermore, when adjusting the valve body, one hand needs to lift the lever and the other hand needs to turn the valve rod through the handle. In areas where valve bodies and pipelines are densely installed, it is inconvenient to operate with both hands, resulting in low practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lockable regulating valve includes a valve body, a mounting base fixedly connected to the outer surface of the valve body, a positioning groove arranged in a ring array on the upper surface of the mounting base, a valve stem provided on the inner wall of the mounting base, a locking disc fixedly connected to the upper end of the valve stem, a symmetrically distributed through hole on the upper surface of the locking disc, a positioning rod slidably connected to the inner wall of the through hole, and the lower end of the positioning rod movably inserted into the inner wall of one of the positioning grooves.

[0008] The outer surface of the positioning rod is provided with an elastic locking device, and the elastic locking device includes an annular stop, the inner wall of which is fixedly sleeved with the outer surface of the positioning rod.

[0009] Preferably, a support spring is movably sleeved on the outer surface of the positioning rod, and one end of the support spring is fixedly connected to the upper surface of the annular stop.

[0010] Preferably, the other ends of the two support springs are fixedly connected to the lower surface of the locking disc, and the upper end of the positioning rod is fixedly connected to a mounting block.

[0011] Preferably, the opposing surfaces of the two mounting blocks are each fitted with a pressing rod via bearings, and a drive handle is fixedly connected to the outer surface of the locking disc, with a limit groove formed on the upper surface of the drive handle.

[0012] Preferably, a limiting slider is slidably connected to the inner wall of the limiting groove, and a return spring is fixedly connected to one side surface of the limiting slider, with one end of the return spring fixedly connected to one side inner wall of the limiting groove.

[0013] Preferably, the upper surface of the limiting slider is fixedly connected to a pressing block, and the lower surface of the pressing block contacts the upper surfaces of the driving handle and the locking disc respectively.

[0014] Preferably, the upper surface of the extrusion block is provided with an extrusion ramp and a pushing ramp.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the elastic locking device enables the valve stem to rotate and be adjusted by pushing the extrusion block to compress the extrusion rod, causing the extrusion rod to drive the positioning rod out of the positioning groove. After adjustment, the valve stem is locked by releasing the extrusion block, preventing the valve stem from rotating under external force. This design allows for one-handed operation, improving ease of use. Attached Figure Description

[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a lockable regulating valve, including a valve body 1, a mounting base 2 fixedly connected to the outer surface of the valve body 1, a positioning groove 3 arranged in a ring array on the upper surface of the mounting base 2, a valve stem 4 provided on the inner wall of the mounting base 2, the lower end of the valve stem 4 connected to the valve inside the valve body 1, a locking disc 5 fixedly connected to the upper end of the valve stem 4, a through hole 6 symmetrically distributed on the upper surface of the locking disc 5, a positioning rod 7 slidably connected to the inner wall of the through hole 6, and the lower end of the positioning rod 7 movably inserted into the inner wall of one of the positioning grooves 3;

[0028] The outer surface of the positioning rod 7 is provided with an elastic locking device, and the elastic locking device includes an annular block 8, the inner wall of which is fixedly sleeved with the outer surface of the positioning rod 7.

[0029] A support spring 81 is movably sleeved on the outer surface of the positioning rod 7. One end of the support spring 81 is fixedly connected to the upper surface of the annular stop 8. The elastic force of the support spring 81 drives the positioning rod 7 to reset and move through the annular stop 8.

[0030] The other ends of the two support springs 81 are fixedly connected to the lower surface of the locking disc 5, and the upper end of the positioning rod 7 is fixedly connected to the mounting block 82. The locking disc 5 serves to support and fix one end of the support spring 81.

[0031] The two mounting blocks 82 have pressing rods 83 mounted on their opposing surfaces via bearings. A drive handle 84 is fixedly connected to the outer surface of the locking disc 5. A limit groove 85 is provided on the upper surface of the drive handle 84. The pressing rods 83 rotate through the cooperation of bearings, thereby reducing the friction during pressing.

[0032] The inner wall of the limiting slide groove 85 is slidably connected to the limiting slider 86. A return spring 87 is fixedly connected to one side surface of the limiting slider 86. One end of the return spring 87 is fixedly connected to one side inner wall of the limiting slide groove 85. The elastic force of the return spring 87 drives the limiting slider 86 to move back to its original position.

[0033] The upper surface of the limiting slider 86 is fixedly connected to the pressing block 88. The lower surface of the pressing block 88 contacts the upper surfaces of the drive handle 84 and the locking disc 5 respectively. The limiting slider 86 improves the stability of the pressing block 88 when it moves and also drives the pressing block 88 to reset and move.

[0034] The upper surface of the extrusion block 88 is provided with an extrusion slope 89 and a pushing slope 810, and the pushing slope 810 is provided with anti-slip grooves distributed in a linear array.

[0035] The elastic locking device enables the valve stem 4 to rotate and be adjusted by pushing the extrusion block 88 to press the extrusion rod 83, causing the extrusion rod 83 to drive the positioning rod 7 out of the positioning groove 3. After adjustment, the valve stem 4 is locked by releasing the extrusion block 88, preventing the valve stem 4 from rotating under external force. It also allows for one-handed operation, improving ease of use.

[0036] The working process of this utility model:

[0037] Step 1: When it is necessary to adjust the valve body 1, first hold the drive handle 84 and push the push slope 810 of the extrusion block 88 with your thumb. The movement of the extrusion block 88 drives the return spring 87 to compress and retract through the limit slider 86. The movement of the extrusion block 88 also compresses the lower end of the extrusion rod 83 through the extrusion slope 89. After being compressed, the extrusion rod 83 reduces the extrusion friction by rotating. Through continuous compression, it drives the mounting block 82 and the positioning rod 7 to move upward. The upward movement of the positioning rod 7 causes its lower end to disengage from the limit of the positioning groove 3 and compresses and retracts the support spring 81 through the annular stop block 8.

[0038] Step two: At this time, rotate the drive handle 84. The rotation of the drive handle 84 drives the valve stem 4 to rotate and adjust through the locking disc 5. When it is rotated to the appropriate angle, release the squeezing block 88. At this time, the reset force of the reset spring 87 drives the squeezing block 88 to reset and move through the limit slider 86. The reset movement of the squeezing block 88 makes its squeezing force on the squeezing rotating rod 83 disappear. At the same time, the elastic force of the support spring 81 drives the positioning rod 7 to reset and move downward through the annular stop block 8, so that the lower end of the positioning rod 7 is inserted into the corresponding positioning groove 3, thereby limiting the angle of the valve stem 4 after rotation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
