Problems solved by technology

[0003] In the underground well diversion system of the city, the control valve with the control pipeline is usually installed at the wellhead. However, because the underground space and the ground have a distance from one end, the valve stem of the ordinary ball valve cannot be flush with the wellhead. When the valve needs to be adjusted Sometimes it is necessary to use a ladder to enter the underground operation, which is time-consuming and laborious, and the underground environment is dirty and messy, which seriously endangers the physical and mental health of the staff, and the opening and closing parts of the existing ball valve are squeezed by the flowing liquid or gas, causing the opening and closing parts hard to turn off instantly

Abstract

The invention provides an improved ball valve. A valve body, a valve set and a valve rod set are included. The improved ball valve is characterized in that the valve set is arranged in the valve body,the valve body is provided with the valve rod set in a rotation connecting manner, and the valve rod set and the valve set are connected. The improved ball valve can solve the problems that a valve rod of an ordinary ball valve cannot be flush with the well mouth position, when the valve needs to be adjusted, a ladder needs to be used for entering for underground operation, time and labor are consumed, the underground environment is dirty, messy and bad, the physical and psychological health of workers is seriously impaired, in addition, an opening and closing piece of an existing ball valveis subjected to the extrusion action of flowing liquid or gas, and consequently the opening and closing piece cannot be easily closed instantly.

Description

technical field [0001] The invention relates to the field of valves, in particular to an improved ball valve. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can be used for the regulation and control of fluid and gas. [0003] In urban underground well diversion systems, control valves with control pipes are usually located at the wellhead. However, due to the distance between the underground space and the ground at one end, the valve stem of the ordinary ball valve cannot be flush with the wellhead. When the valve needs to be adjusted Sometimes it is necessary to use a ladder to enter the underground operation, which is time-consuming and laborious, and the underground environment is dirty and messy, which seriously endangers the physical and mental health of the staff, and the opening and closing parts of the existing ball valve are squeezed by the flowing liquid o...
