Abstract

The invention discloses a ball valve with a random adjustment preventing function. The ball valve comprises a valve body, wherein a valve cavity is formed in the valve body, a left channel is arrangedin the left side of the valve body, a right valve cover is mounted on the valve body, a right channel is arranged on the right valve cover, and a ball core is rotatably connected in the valve cavity.A shaft hole is formed in the upper end of the ball cover, and a valve rod, the lower end of which stretches into the shaft hole, is rotatably connected in the valve body; a left positioning groove and a right positioning groove communicating to the shaft hole are symmetrically formed in two sides of the shaft hole in the ball core; the valve rod is provided with a cutting groove, and a left positioning bar and a right positioning bar which are symmetrically arranged are hinged in the cutting groove; a core shaft is slidably connected in the valve rod, the lower end of the core shaft extendsinto the cutting groove, a left connecting rod and a right connecting rod which are symmetrically arranged are hinged to the lower end of the core shaft, the left connecting rod is hinged to the leftpositioning bar, and the right connecting rod is hinged to the right positioning bar; and a password assembly is arranged on the outer side of the valve rod. The ball valve is simple in structure, andrandom adjustment of the ball valve can be prevented.

Description

technical field [0001] The invention belongs to the technical field of pipeline valves, in particular to a ball valve with anti-arbitrary adjustment function. Background technique [0002] Ball valves are widely used in oil field wellheads, oil tanks, gathering stations, oil and gas pipeline systems, and petrochemical industries. People usually use valves such as ball valves to control the flow of liquid and gas, and most of these ball valves can be opened and closed freely. Due to the need for management, ball valves in some positions are prohibited from being opened and closed at will, such as the main pipeline gate, etc., and a locking device is required on the ball valve to prevent others from opening the valve without authorization to steal oil and gas. In order to achieve the anti-theft effect, various anti-theft ball valves have appeared on the market. Some anti-theft ball valves have complex structures and are inconvenient to use; while some anti-theft ball valves ha...
