Description

Technical Field

[0001] The utility model relates to the technical field of plug valves, in particular to a multifunctional plug valve. Background Art

[0002] The plug valve is a rotary valve in the shape of a closing piece or a plunger. It is a valve that can be opened or closed by rotating 90 degrees to connect or separate the channel opening on the valve plug with the channel opening on the valve body. The shape of its valve plug can be cylindrical or conical. In a cylindrical valve plug, the channel is generally rectangular; while in a conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light and compact. It is most suitable for cutting off and connecting media and for diversion.

[0003] When the existing plug valves on the market are in use, they generally use a handle to drive the rotation of the valve shaft. In order to make the structure more labor-saving, the handle part is set to be longer. When it is closed, the handle is horizontally arranged with the tube body, and when it is opened, the handle is vertical to the tube body. This will take up a large space. In some relatively narrow spaces, the valve body will cause interference to the passing of surrounding people when in use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a multifunctional plug valve. When the plug valve is in use, whether in an open state or a closed state, the handle can be placed in a parallel state with the pipeline, which can effectively reduce the space occupied by the whole and adapt to more places of use. In addition, the arrangement of the indicator bar and the indicator groove further facilitates the user's judgment on the open or closed state.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multifunctional plug valve comprises a valve body, wherein a valve shaft is arranged in the valve body, and the upper end of the valve shaft extends to the outside; an adjusting mechanism, wherein the adjusting mechanism comprises a first rotating shaft rotatably connected to the upper end of the valve shaft, a rotating groove is opened at the upper end of the first rotating shaft, and a second rotating shaft is rotatably connected between the front and rear inner walls of the rotating groove, a rotating rod is fixed on the second rotating shaft, and a grip rod is fixedly connected to the right end of the rotating rod, and four groups of limit assemblies are fixedly connected to the upper end of the valve shaft in a circular shape, and each group of the limit assemblies is composed of two vertical baffles; an indicating mechanism, wherein the indicating mechanism is used to indicate the rotation angle.

[0007] Preferably, a rubber layer is provided on the outer side of the grip rod.

[0008] Preferably, a slot space is formed between every two matched vertical baffles, and the gripping rod is located in one of the slot spaces.

[0009] Preferably, the second rotating shaft is a damping rotating shaft.

[0010] Preferably, the indicating mechanism comprises an indicating ring fixedly connected to the upper end of the valve body, and a plurality of indicating grooves are formed at the upper end of the indicating ring.

[0011] Preferably, an indicator strip is fixedly connected to the side wall of the valve shaft, and the indicator strip cooperates with a plurality of indicator grooves.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When the indicator strip is located on the left and right sides of the valve shaft, the valve body is in a sealed state; when the indicator strip is located on the front and rear sides of the valve shaft, the valve body is in a closed state. The use of the indicator strip and the indicator groove allows the staff to accurately judge the state of the internal valve plate, and with the cooperation of the first rotating shaft, the second rotating shaft and the grip, the grip occupies a smaller space regardless of whether it is in the open or closed state, and will not affect the movement of surrounding personnel.
