Description

Technical Field

[0001] The utility model relates to the technical field of valve accessories, in particular to a valve handle with a positioning function. Background Art

[0002] Valves, such as ball valves, are widely used in chemical, electric power, municipal and other industries. They are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. During the use of the valve, the valve handle is required to control the opening and closing of the valve.

[0003] According to a multi-purpose valve handle with application number 202121553518.X, this solution provides at least one set of auxiliary limit holes so that multiple valves can be controlled by a single valve handle. There is no need to carry multiple valve handles, which makes it more applicable and convenient to use.

[0004] However, the following problems still exist in actual use:

[0005] (1) This type of multi-purpose valve handle cannot effectively position the valve during actual use, which may cause the valve to open or close accidentally. It cannot reasonably ensure that the valve remains in the current state, which reduces the stability of the valve and affects the normal use of the valve.

[0006] (2) This multi-purpose valve handle is not easy for the staff to operate. Since the valve opening and closing requires manual control by the staff, the staff's labor intensity during adjustment will also increase the corresponding adjustment time. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a valve handle with a positioning function, which has the advantages of positioning the current state of the valve and facilitating operation by staff, thereby solving the problems raised in the background technology.

[0008] The utility model provides the following technical solutions: a valve handle with a positioning function, comprising an outer shell, a fixing mechanism is arranged inside the outer shell, the fixing mechanism comprises a second clamping block, a second connecting block, a second hinged seat, a receiving block, a first hinged seat, a first connecting block and a pressing block, the receiving block is rotatably connected to the inner wall of the outer shell, the first hinged seat is fixedly connected to the receiving block, the first connecting block is rotatably connected to the first hinged seat, the pressing block is fixedly connected to the first connecting block, the second hinged seat is fixedly connected to the receiving block, the second connecting block is rotatably connected to the second hinged seat, the second clamping block is fixedly connected to the second connecting block, and the second clamping block is fitted with the inner wall of the outer shell.

[0009] Preferably, a control mechanism is provided on one side of the shell, and the control mechanism includes a handle, a fixed rod, a connecting rod and a first clamping block, the first clamping block is slidably plugged into the shell, the first clamping block is fixedly connected to the fixed rod, the connecting rod is fixedly connected to the fixed rod, and the handle is fixedly connected to the connecting rod.

[0010] Preferably, a limit block is slidably inserted on one side of the shell, and a receiving rod is fixedly connected to one side of the limit block. The receiving rod is slidably inserted into the shell, and two groups of reserved grooves are provided inside the receiving rod. Both groups of reserved grooves are engaged with the second clamping block, so as to achieve the effect of adjusting the horizontal position of the limit block, so that the limit block is separated from the inside of the valve stem after the valve is opened and closed.

[0011] Preferably, one end of the receiving rod is fixedly connected to a fixed block, the fixed block is slidably connected to the shell, one side of the fixed block is fixedly connected to a first spring, the other end of the first spring is fixedly connected to the shell, and the fixed block is fitted with the first clamping block.

[0012] Preferably, the inner wall of the receiving block is fitted with a limiting rod, and the limiting rod is fixedly connected to the shell, which can achieve the effect of limiting the receiving block, so that the receiving block deflects with the limiting rod as the center.

[0013] Preferably, a second spring is fixedly connected to one side of the second clamping block, and the other end of the second spring is fixedly connected to the housing.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. When positioning the valve, the valve handle with a positioning function first presses the pressure block, and the pressure block causes the first connecting block to move horizontally along the inner wall of the shell, and the first hinge seat causes the first connecting block to move more stably, so that one end of the receiving block rotates inward, and the other end of the receiving block rotates outward through the limit rod, and the second clamping block follows the receiving block to move outward through the second hinge seat and the second connecting block, so that the second clamping block is separated from the inner wall of the reserved groove, and the elastic force of the first spring causes the receiving rod and the limit block to return to their original positions, so that the limit block fits with the inner wall of the shell. The arrangement of this structure effectively avoids the problem of accidental opening and closing of the valve stem after the valve control is completed, and can achieve the effect of positioning the valve stem. At the same time, it improves the stability of the valve stem during use, avoids accidental opening and closing of the valve, and can also improve the safety of the valve stem during actual use.

[0016] 2. For this valve handle with a positioning function, when opening and closing the valve, first, the first clamping block is slidably inserted into the interior of the shell, so that the first clamping block is fitted with the fixed block, and the handle is pushed. The fixed rod and the first clamping block are driven inward by the handle, thereby pushing the fixed block and the receiving rod to move horizontally along the inner wall of the shell, so that the limit block is clamped into the inside of the valve stem. When the reserved groove moves to the same horizontal plane as the second clamping block, the second clamping block is clamped into the inner wall of the reserved groove by the elastic force of the second spring, and the receiving rod is limited by the second clamping block. The handle is turned, and the shell and the limit block are driven to rotate by the handle, thereby controlling the opening and closing of the valve through the valve stem. The setting of this structure effectively avoids the problem that the valve handle is difficult to install, and can achieve the effect of facilitating the staff to assemble the valve handle. At the same time, it reduces the time required for controlling the opening and closing of the valve, improves the corresponding work efficiency, and can also improve the convenience of the valve handle during actual use.

[0026] Working principle: when opening and closing the valve, the first clamping block 10 is slidably inserted into the interior of the housing 1, so that the first clamping block 10 is fitted with the fixing block 9, and the handle 3 is pushed. The fixing rod 4 and the first clamping block 10 are driven to move inward by the handle 3, thereby pushing the fixing block 9 and the receiving rod 6 to move horizontally along the inner wall of the housing 1, so that the limit block 2 is clamped into the interior of the valve stem.
