Description

Electric and manual double-mode switching valve Technical Field The utility model relates to the technical field of valves, in particular to an electric-manual dual-mode switching valve. Background In the existing valve application scenario, the electric valve and the manual valve have advantages and limitations respectively. The electric valve has the characteristics of convenient operation and high automation degree, can realize remote control and accurate adjustment, and is widely applied to large-scale industrial production systems and intelligent control systems. However, the electric valve depends on power supply, and when power failure, circuit failure or control system damage are encountered, the valve cannot operate normally, and the operation and safety of the pipeline system are seriously affected. The manual valve is not limited by electric power conditions, and can be opened and closed by manual operation even under emergency conditions, so that the manual valve has higher reliability and stability. In the prior art, although the traditional manual and electric integrated valve can be switched between manual operation and electric operation, the traditional valve is fixed in the diameter of a turntable during manual operation, so that the length of a force arm is fixed, an operator needs to consume a large amount of physical force due to the fixed force arm of a handle, the operation efficiency is low, the operator is easy to fatigue after long-time operation, and the risk of misoperation is increased. In addition, the fixed length handle occupies a large space when the valve is idle, which is detrimental to compact layout, transportation and routine maintenance of the device. Therefore, developing a valve with both electric and manual operation modes and with an adjustable handle length during manual operation is a key to solving the above problems. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an electric and manual dual-mode switching valve, which can normally and efficiently operate under different working conditions by arranging an electric operation mode and a manual operation mode and providing a convenient mode switching structure, so that the use flexibility and reliability of the valve are improved, the valve can be rapidly switched to a manual operation mode under special conditions such as power interruption, the normal operation of the valve is ensured, meanwhile, the unfolding length of a handle can be flexibly adjusted during manual operation, the force arm is increased by utilizing the lever principle, the force application intensity of an operator is obviously reduced, the operation efficiency is improved, after the use is finished, the handle can be contracted, the whole volume of the valve is greatly reduced, the equipment storage, the transportation and the maintenance are facilitated, and the applicability, the reliability and the economy of the valve under different application scenes are comprehensively improved. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The electric-manual double-mode switching valve comprises a screw valve main body, wherein a first connecting pipe and a second connecting pipe which are communicated with the screw valve main body are fixedly connected to the side walls of the two ends of the screw valve main body respectively, a connecting flange is arranged at the upper end of the screw valve main body, a screw is connected in a rotating mode to the screw valve main body, a valve core matched with the screw is arranged in the screw valve main body, the screw penetrates through the connecting flange and is in rotary connection with the screw, a turntable is fixedly connected to the upper end of the screw, four sliding grooves which are distributed at equal intervals in the circumferential direction are formed in the side walls of the turntable, sliding rods are connected in the four sliding grooves in a sliding mode, handles are fixedly connected to the end parts of the sliding rods, an adjusting mechanism used for adjusting the handles is arranged on the sliding rods, and the adjusting mechanism comprises a groove formed in the upper end of the sliding rods, and a positioning block is connected in the groove in a sliding mode.
