Manual container valve

Abstract

The invention discloses a manual container valve. The manual container valve comprises a valve body, a piston rod and a hydraulic unit, the valve body is in a hollow pipe shape with two ends being open, the middle of the valve body is provided with a connecting mouth, the piston rod is vertically located inside the valve body, the outer surface of the upper end of the piston rod is provided with adisc, the periphery surface of the disc is slidably connected with the inner wall of the valve body with no seam, the lower end of the piston rod is provided with a plug head, the valve body is internally provided with an annular embossment matched with the plug head and is internally provided with a cavity separating ring, the inner periphery surface of the cavity separating ring is slidably connected with the outer surface of the piston rod with no seam, the part, between the cavity separating ring and the disc, of the valve body is provided with a first liquid hole communicating with the outside, the upper end surface of the valve body is fixedly connected with a seal cover, the seal cover seals the upper end of the valve body and is provided with a second liquid hole communicating with the valve body, and the hydraulic unit communicates with the first liquid hole and the second liquid hole correspondingly. By means of the manual container valve, the opened cross section of the container valve can be controlled accurately, so that the air outlet quantity and air pressure strength can be effectively controlled.

Description

technical field [0001] The invention relates to the field of valves, in particular to a manual container valve. Background technique [0002] Now most of the container valves are opened by direct pushing and piercing, which has the characteristics of simple structure and high safety strength. However, the container valves designed in the above two ways cannot control the cross-section of the valve opening, so that the pressure and flow of the outlet gas cannot be well controlled, and there is a large gap for accurate control. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the object of the present invention is to provide a manual container valve, which can accurately control the opening cross section of the container valve, thereby effectively controlling the air output and air pressure intensity. [0004] The purpose of the present invention is achieved by such a technical scheme, the manual container valve includes a valve bo...
