Description

Technical Field

[0001] The utility model relates to the field of heat pipe ball valves, and particularly to a quick-opening handle for a ball valve. Background Art

[0002] In a heat pipe pipe network, if the spherical valve well is small or the ventilation of the single-eye well is poor, it will cause corrosion of the valve handle, thus affecting the use of the valve when opening and closing. At the same time, due to limitations, it is impossible to operate or difficult to operate. Using the original valve handle with uneven force will result in a longer time for opening and closing the valve, thus affecting the working time of the valve, and at the same time, it will reduce or damage the service life of the valve, and may cause personal accidents or pose safety hazards. Content of the Utility Model

[0003] An object of the utility model is to provide a quick-opening handle for a ball valve that can at least solve any one of the above technical problems.

[0004] A further object of the utility model is to avoid being limited by the terrain so as to facilitate the opening and closing operations of spherical valves in narrow spaces.

[0005] Another further object of the utility model is to ensure the opening and closing of the valve when the original valve handle has problems.

[0006] Specifically, the utility model provides a quick-opening handle for a ball valve, which includes a boosting rod and an extension rod. Sleeve rods that slide along the boosting rod are arranged at both ends of the boosting rod; one end of the extension rod is fixedly connected to the boosting rod, and a first switch notch is arranged at the other end.

[0007] Furthermore, a fixing cylinder is arranged at the end of the extension rod. The fixing cylinder is slidably connected to the end of the extension rod, and a second switch notch is arranged inside the fixing cylinder.

[0008] Furthermore, a sliding groove is arranged on the outer wall of the first switch notch close to the first switch notch, and a sliding block corresponding to the sliding groove is arranged on the inner wall of the fixing cylinder. The sliding block moves radially along the sliding groove.

[0009] Furthermore, the diameter of the second switch notch is larger than that of the first switch notch.

[0010] Furthermore, the extension rod is threadedly connected to the boosting rod.

[0011] Technical Effects and Advantages of the Utility Model

[0012] The utility model sets a boosting rod and an extension rod for the situation that the valve well of the heating pipe network is restricted by space or the ventilation in a single-eye well is poor, so as to avoid maintenance personnel directly entering the well with thin oxygen for maintenance work, and at the same time avoid problems such as the handle causing inoperability or difficult operation. The present invention lengthens and enlarges the existing handle, realizes the operation of the well from the ground, improves the safety of pipeline valve maintenance personnel, reduces the labor intensity, and prolongs the service life of the valve.
