Multifunctional valve

Abstract

The invention discloses a multifunctional valve. Three communicated flow passages are arranged in a valve main body of the multifunctional valve; each flow passage comprises a conical hole and a cylindrical hole, wherein one flow passage is positioned on the axial line of the valve main body; the other two flow passages are in bilateral symmetry by using the flow passage positioned on the axial line as the symmetry axis; an identical conical piston is arranged in each flow passage; a fixing rod is arranged in the cylindrical hole; a spring sleeves a rod body at the section, coaxial with the cylindrical hole, of the fixing rod; the upper end of the spring is connected with the piston; the other end of the spring is welded at the surface of the fixing rod; three pulleys are arranged in the flow passage at the crossed and converged part of the three flow passages; a first elastic rope bypasses the three pulleys; the middle is connected with a second elastic rope connected with the small end surface of the piston positioned in the middle; in a natural state, the first elastic rope and the second elastic rope freely and straightly extend. The multifunctional valve has the advantages that the pressure intensity of each container after the filling can be enabled to be maintained in the identical range; the automatic regulation and flow division can also be realized; the filling efficiency is accelerated.

Description

technical field [0001] The invention belongs to the technical field of fluid control, and in particular relates to a valve. Background technique [0002] In industrial production or engineering applications, it is often encountered that multiple containers are filled with the same amount of fluid, and no matter how much the container is filled, the pressure in the container after filling should be kept within a certain range. Especially for gas. At present, there is no such special valve. In practice, most of them are realized by constant pressure components or devices. Either the structure is complex, or it cannot automatically control the automatic stop or automatic diversion to another pipeline after the pressure in each distribution pipeline reaches the standard. to go. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a multi-functional valve, which can not only ensure that the pressure of ea...
