A valve with high versatility and high practicability with lock

Abstract

A lockable valve with high versatility and high practicability relates to the technical field of valves, including a delivery pipe, the inner wall of the delivery pipe is provided with evenly distributed limiting grooves, the inner wall of the limiting groove is fixedly connected with friction strips, and the delivery pipe The middle part of the ball valve is movably connected with a ball valve, the inner wall of the ball valve is fixedly connected with evenly distributed spring one, the inner side of spring one is fixedly connected with a movable block movably connected with the inner wall of the ball valve, and the outer side of the movable block is fixedly connected with spring two. The valve with high versatility and high practicability is used through the cooperation of the limit block and the limit groove. When using the ball valve, the slider will move to the bottom under the action of the spring three, and the movable block will be extruded outward. , so that the limit block rotates to the outside and engages with the limit groove, one-way restricts the rotation of the ball valve. At this time, the ball valve can only rotate in one direction, so as to achieve the effect of self-locking, limit the rotation direction of the valve, and ensure the safety of the valve. It is safe to use, and has high practicability and versatility.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a lock valve with high versatility and practicability. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and 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 of the valve, affecting production and manufacturing, and the valve without a lock is easy to be rotated artificially, resulting in the occurrenc...

AI Technical Summary

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.
