Lock valve with high universality and practicability

Abstract

The invention discloses a lock valve with high universality and practicability, and relates to the technical field of valves. The lock valve comprises a conveying pipe, wherein limiting grooves whichare uniformly distributed are formed in the inner wall of the conveying pipe, friction strips are fixedly connected to the inner walls of the limiting grooves, a ball valve is movably connected to themiddle of the conveying pipe, the inner wall of the ball valve is fixedly connected with first springs which are uniformly distributed, the inner sides of the first springs are fixedly connected withmovable blocks which are movably connected with the inner wall of the ball valve, and the outer sides of the movable blocks are fixedly connected with second springs. According to the lock valve withhigh universality and practicability, limiting blocks and the limiting grooves are matched to use, when the ball valve is used, a sliding block can move to the bottom under the action of a third spring, the movable blocks are extruded outwards, the limiting blocks rotate outwards and are clamped with the limiting grooves, the rotation of the ball valve is limited unidirectionally, and the ball valve can only rotate in one direction at the time, so that the self-locking effect is achieved, the rotation direction of the valve is limited, the use safety of the valve is guaranteed, and the practicability and universality are high.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a lockable valve with high versatility and high practicability. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Most of the current valves do not have a self-locking function. During use, the valve can be adjusted freely, resulting in a change in the flow rate of the valve, affecting production and manufacturing, and the valve without a lock is easy to be turned artificially, resulting ...

Problems solved by technology

[0003] Most of the current valves do not have a self-locking function. During use, the valve can be adjusted freely, resulting in a change in the flow rate of the valve, affecting production and manufacturing, and the valve without a lock is easy to be turned artificially, resulting in a change in the flow rate. Changes will affect the rate of circulation, and even cause harm. The practicability and versatility are low, and it may even cause the pipeline to be squeezed and ruptured. The constant flow rate is the key to transportation.
