Abstract

The invention discloses a multifunctional stop valve, and belongs to the field of valves. The multifunctional stop valve comprises a pipe body, a plug and a connecting rod system, wherein the connecting rod system comprises an operation component, a limiting plate and a rod component; the connecting rod system is arranged to control mounting and dismounting of the plug in the pipe body, so that apipeline has multiple functions; when a handle is moved to the uppermost side and cannot continue to move, a threaded hole is blocked by the plug, the pipeline is firmly blocked and closed, and cannotachieve a water passing function; when the handle is easily screwed to move downwards and partly and the plug is still located in the threaded hole, a fixing rod has left-right moving space, and at the moment, the function of the stop valve is achieved under the action of a first compression spring; the first compression spring is reversely extruded to generate a gap which water can pass through;and the threaded hole is blocked for sealing by the plug in the direction opposite to the force direction of the first compression spring; when the handle is screwed down forcibly, the plug can slideinto a slide way from the threaded hole, and at the moment, only a common pipeline water passing function is achieved.

Description

Technical field [0001] The present invention relates to valves, and more particularly, relates to a multifunctional shut-off valve. Background technique [0002] Valve control means is a fluid delivery system, having a cut-off regulation of flow, to prevent reflux, regulation, diversion or overflow relief functions. A control valve for a fluid system, from the simplest to the shut-off valve extremely complex various valves used in automatic control system, which is quite numerous varieties and specifications. [0003] Cut-off valve is widely used in all aspects of life in our production, however, the existing shut-off valve in the pipe after installation, can only complete a single function in the face of today's era of rapid development, single-function valve can not meet the class requirements. Inventive content [0004] 1. Technical issues to be solved [0005] For the prior art problems, an object of the present invention to provide a multifunctional shut-off valve, which mo...
