Description

Technical Field

[0001] The utility model relates to the technical field of valve auxiliary appliances, and particularly relates to a combined operating device. Background Technique

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system and has functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.

[0003] During the use of valves, some valves need to be frequently started and closed. However, when the existing valves rotate, for good sealing effects, they are generally tightened tightly. When starting again, users need to spend a lot of effort. Moreover, some valves are installed in limited spaces, making it inconvenient for users to rotate them, and thus inconvenient for users to use. For this reason, we propose a combined operating device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a combined operating device, which cooperates with structures such as a limit block, an operating rod, a sleeve, and an adjusting mechanism to solve the problem that existing valves are inconvenient for users to operate.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A combined operating device includes a valve. A valve shaft is fixedly connected to the top of the valve. It further includes: a limit block is fixedly connected to the top of the valve, and a plurality of the limit blocks are radially distributed along the top of the valve. A sleeve is sleeved outside the valve shaft. A limit pin is detachably arranged at the top of the valve shaft. An operating rod is fixedly connected to the outside of the sleeve. A thickening layer is fixedly connected to the outside of the operating rod, and the thickening layer is located at the contact point between the limit block and the operating rod; and an adjusting mechanism fixed on the operating rod, and the adjusting mechanism is used to adjust the length of the operating rod.

[0007] Preferably, the adjusting mechanism includes an outer cylinder. A rotating block is rotatably connected inside the outer cylinder. A connecting rod is fixedly connected to the outside of the rotating block, and the connecting rod is convenient for driving the rotating block to rotate.

[0008] Preferably, fixing rods are symmetrically fixedly connected to the outside of the connecting rod. Sleeve heads are fixedly connected to the outside of both of the fixing rods. The sleeve heads are made of rubber material, which is convenient for users to use.

[0009] Preferably, a lead screw is fixedly connected to the side of the rotating block away from the connecting rod. A slider is rotatably connected to the outside of the lead screw. The slider is slidably connected to the inner wall of the outer cylinder. An inner cylinder is fixedly connected to the outside of the slider. The outer cylinder facilitates limiting the slider.

[0010] Preferably, one end of the lead screw away from the connecting rod is rotatably connected to a connecting block. One end of the inner cylinder away from the slider is fixedly connected to the operating rod. The inner cylinder facilitates increasing the length of the operating rod.

[0011] Preferably, an anti-slip sleeve is fixedly connected to the outside of the end of the outer cylinder close to the connecting rod. The anti-slip sleeve is made of rubber material. The anti-slip sleeve facilitates anti-slip.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In this solution, through the mutual cooperation of structures such as the limiting block, the sleeve, and the operating rod, the limiting block plays a role in fixing the operating rod, facilitating the user to rotate the valve, thus facilitating the user to operate the valve, which is beneficial to improving the work efficiency of the user. At the same time, when the number of limiting blocks increases, the device can be operated in a smaller space, and the layout of the valve can be optimized;

[0014] 2. This solution is provided with an adjustment mechanism.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1: As Figure 1 - Figure 6 shown, a combined operating device in the figure includes a valve 1. A valve shaft 3 is fixedly connected to the top of the valve 1. The valve shaft 3 is used to start and close the valve 1. It also includes: A limit block 2 is fixedly connected to the top of the valve 1. There can be four limit blocks 2, and at the same time, it can be set to six or eight according to needs. Multiple limit blocks 2 are radially distributed along the top of the valve 1. At the same time, when the number of limit blocks 2 increases, the device can be operated in a smaller space, which can optimize the layout of the valve 1. A sleeve 5 is sleeved outside the valve shaft 3. A limit pin 4 is detachably arranged at the top of the valve shaft 3. The limit pin 4 is used to limit the sleeve 5, so that the sleeve 5 can be sleeved and fixed outside the valve shaft 3. An operating rod 6 is fixedly connected to the outside of the sleeve 5. The operating rod 6 is used to facilitate the rotation of the valve 1. A thickened layer 7 is fixedly connected to the outside of the operating rod 6. The thickened layer 7 is made of steel. The thickened layer 7 is located at the contact point between the limit block 2 and the operating rod 6, mainly to increase the strength; and, an adjusting mechanism 8 fixed on the operating rod 6. The adjusting mechanism 8 is used to adjust the length of the operating rod 6, thereby changing the torque and facilitating the operation of the user.

[0024] Further, please refer to Figure 2 , the adjusting mechanism 8 includes an outer cylinder 9. The outer cylinder 9 is made of stainless steel. A rotating block 10 is rotatably connected inside the outer cylinder 9. A connecting rod 11 is fixedly connected to the outside of the rotating block 10. Fixed rods 12 are symmetrically fixedly connected to the outside of the connecting rod 11. Sockets 13 are fixedly connected to the outside of both fixed rods 12. The sockets 13 are made of rubber. The connecting rod 11 and the fixed rods 12 form a cross structure, which is convenient for the user to rotate the connecting rod 11.

[0025] Embodiment 2: As Figure 5 and Figure 6As shown in the figure, this is a further description of the first embodiment. In this embodiment, a lead screw 14 is fixedly connected to the side of the rotating block 10 away from the connecting rod 11. A slider 15 is rotatably connected to the outside of the lead screw 14. The lead screw 14 is used to drive the slider 15 to slide. The slider 15 is slidably connected to the inner wall of the outer cylinder 9, which can play a role in limiting the slider 15 to ensure its horizontal movement. An inner cylinder 16 is fixedly connected to the outside of the slider 15. The inner cylinder 16 is used to extend the length of the operating rod 6. The outer wall of the inner cylinder 16 is close to but does not contact the outer cylinder 9. One end of the lead screw 14 away from the connecting rod 11 is rotatably connected to a connecting block 17. One end of the inner cylinder 16 away from the slider 15 is fixedly connected to the operating rod 6. By rotating the fixing rod 12, the fixing rod 12 drives the rotating block 10 to rotate through the connecting rod 11, thereby driving the lead screw 14 to rotate, which drives the slider 15 to slide along the inner wall of the outer cylinder 9, and then the inner cylinder 16 extends, thereby increasing the length of the operating rod 6, facilitating the adjustment of the length of the operating rod 6 according to requirements, so as to adapt to valves 1 of different sizes and facilitate user operation.

[0026] Specifically, an anti-slip sleeve 18 is fixedly connected to the outside of one end of the outer cylinder 9 close to the connecting rod 11. The anti-slip sleeve 18 is made of rubber material. The anti-slip sleeve 18 can prevent slipping. By holding the anti-slip sleeve 18, the operating rod 6 is driven to approach the limit block 2, which is convenient for driving the valve shaft 3 to rotate and facilitating user operation.

[0027] In summary, when using this device, first, the sleeve 5 is sleeved on the outside of the valve shaft 3, and then the limit pin 4 is inserted into the valve shaft 3 to limit the sleeve 5. Then, hold the anti-slip sleeve 18 and rotate it in the required direction to make the operating rod 6 approach the limit block 2, so that the limit block 2 fixes the thickened layer 7 on the outside of the operating rod 6. Then continue to rotate to facilitate starting or closing the valve 1. When it is necessary to adjust the torque, rotate the fixing rod 12. The fixing rod 12 drives the rotating block 10 to rotate through the connecting rod 11, thereby driving the lead screw 14 to rotate, which drives the slider 15 to slide along the inner wall of the outer cylinder 9, and then the inner cylinder 16 extends, thereby increasing the length of the operating rod 6, facilitating the adjustment of the length of the operating rod 6 according to requirements, and thus increasing the torque.
