Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 4, the present embodiment provides a gear adjustment control device, which includes a gear cover 100 and a gear movable seat 200; the gear cover body 100 is provided with an accommodating space, the gear movable seat 200 is located in the accommodating space and can rotate relative to the gear cover body 100, the inner peripheral wall of the gear cover body 100 is provided with an elastic gear mechanism 110, the outer peripheral wall of the gear movable seat 200 is provided with a plurality of gear grooves 210 which are continuously arranged and matched with the elastic gear mechanism 110, and the elastic gear mechanism 110 is matched with one of the gear grooves 210 and used for indicating that the gear movable seat 200 rotates at any damping position; the gear cover 100 and the gear sliding seat 200 are provided with mounting holes 300 coaxially disposed.

The gear adjustment control device that this embodiment provided, when concrete installation, the valve rod of plug valve can wear to establish this mounting hole 300 and install, so that the valve rod drives the relative gear lid 100 rotation of gear sliding seat 200, at this in-process, because the periphery wall of gear sliding seat 200 be equipped with a plurality of continuous settings and with elasticity gear mechanism 110 matched with gear groove 210, elasticity gear mechanism 110 and a cooperation in a plurality of gear grooves 210, can instruct gear sliding seat 200 to rotate at arbitrary damping position, realize the regulation of gear. Simultaneously, gear lid 100 has accommodation space, and gear sliding seat 200 is located accommodation space and can rotate relative to gear lid 100, when specifically installing, can install gear adjusting control device as a whole earlier, then with this gear adjusting control device as whole installation on the plug valve, so set up, can make gear adjusting control device's dismouting on the plug valve more convenient, save operating personnel's dismouting time.

In addition, this gear adjustment controlling means can regard as solitary accessory to use, promptly, it can be installed on current mechanical valve, when this gear controller inefficacy needs the maintenance, need not to take apart holistic gas circuit and change for maintenance operation is more convenient, and can not have the risk of gas leakage after the loading and unloading.

Referring to fig. 3 and 4, the groove surface of the shift groove 210 is an arc surface; the elastic shift position mechanism 110 has an elastic convex surface 111, and the elastic convex surface 111 makes point contact with the arc surface.

The point contact arrangement enables the elastic shift mechanism 110 to smoothly slide into the shift groove 210 through the elastic convex surface 111 when the shift lever movable base 200 rotates, thereby generating a shift feeling.

Optionally, the elastic convex surface 111 is a hemispherical surface or a spherical surface, and both the elastic shift position mechanism 110 and the arc-shaped surface can form point contact, so as to reduce the frictional resistance between the elastic shift position mechanism 110 and the shift position groove 210.

In this embodiment, the gear groove 210 is disposed on the outer peripheral wall of the gear sliding seat 200; the elastic convex surface protrudes from the inner peripheral wall of the gear cover 100, so that the gear groove 210 can be conveniently formed and the gear groove can be conveniently installed in a matched manner.

On the basis of the above embodiment, referring to fig. 4, gear groove 210 axially penetrates through the upper and lower end surfaces of gear sliding seat 200, so that not only is gear groove 210 convenient to machine, but also the vertical length of gear groove 210 can be increased relatively, that is, the vertical position of elastic gear mechanism 110 can be increased, and elastic gear mechanism 110 can be better matched with the gear groove.

Continuing with fig. 4, the outer peripheral wall of gear shift actuator 200 is further provided with a smooth sliding area 220 for elastic gear shift mechanism 110 to move, so as to indicate that gear shift actuator 200 is located at the initial position or the zero position.

Illustratively, when the elastic shift mechanism 110 moves relative to the smooth sliding area 220, the shift is an initial position or a zero position; the sequential sliding of the resilient shift mechanism 110 into the shift slot 210 can be defined as first gear, second gear, third gear, etc.

It should be noted that a gap is left between the inner peripheral wall of the gear cover 100 and the outer peripheral wall of the gear sliding seat 200 to reduce the friction force generated during the rotation between the two, so that the valve rod can drive the gear sliding seat 200 to rotate more smoothly.

In this embodiment, the elastic gear mechanism 110 and the gear cover 100 are integrally formed by injection molding.

Specifically, referring to fig. 5 to 7, the gear cover 100 is a plate structure with an open end and a closed circumferential end opposite to the corresponding mounting 300; the circumference of gear lid 100 is equipped with side opening 120, and at side opening 120 department, elasticity gear mechanism 110 is through injection moulding mode and gear lid 100 integrated into one piece.

Referring to adjustment 4 and fig. 7, at the initial position or the zero position, elastic convex surface 111 of elastic gear mechanism 110 abuts against smooth sliding area 220 of gear sliding seat 200, and as gear sliding seat 200 rotates, it will drive gear groove 210 to rotate, and when gear groove 210 rotates to elastic gear mechanism 110, elastic gear mechanism 110 is squeezed and will generate elastic deformation, so that elastic convex surface 111 of elastic gear mechanism 110 can slide into gear groove 210, and after elastic gear mechanism 110 slides into gear groove 210, elastic deformation disappears, and the foregoing processes are repeated to complete gear switching.

Referring to fig. 8 and 9, the present embodiment further provides a plug valve including the aforementioned shift position adjustment control device. The plug valve provided by the embodiment comprises the gear adjusting and controlling device, and therefore the technical advantages and effects which can be achieved by the plug valve also comprise the technical advantages and effects which can be achieved by the gear adjusting and controlling device, and are not described again.

Concretely, plug valve still includes the valve body, and the valve body includes valve rod 400 and valve gap 500, and gear lid 100 is installed in valve gap 500, and valve rod 400 is all located to gear lid 100 and gear sliding seat 200 through mounting hole 300 cover, and wherein, valve rod 400 is located to the fixed cover of gear sliding seat 200 to rotate together along with valve rod 400.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
