Abstract
The invention discloses a pneumatic valve, and relates to the field of industrial machinery. The pneumatic valve comprises a valve body consisting of two semispherical shells, wherein a pipe-shaped channel is formed in the middle part of the valve body; flange plate joints are arranged at the two ends of the channel; a plastic pipe is arranged in the channel; a sealing ring, in sealing connection with the channel and the plastic pipe, is arranged in the channel; an intake pipe and an exhaust pipe are arranged on the side wall, perpendicular to the channel, of the valve body; an annular projection is arranged on the inner wall of the valve body, and is 6 mm thick; and pressure gauges are arranged on the intake pipe and the exhaust pipe. As the plastic pipe is soft, the plastic pipe can quickly shrink to close when being pressed, the closing is thorough, and the response speed is fast; the sealing ring can prevent outward overflowing of gas pressurizing the valve body; and the annular projection reduces the distance from the inner wall of the valve body to the plastic pipe, so that the acting force of unit volume gas is increased, and the shrinking response speed of the plastic pipe can be effectively accelerated.
Description
Technical field
The present invention relates to a kind of pneumatic valve.
Background technique
Valve is the controlling component in fluid delivery system, the reliability of the excellent direct relation hydraulic work system of its performance, and wherein direct relation control accuracy is the sealing of controlling component.
Summary of the invention
The object of the present invention is to provide a kind of easy to operate pneumatic valve.
The present invention is achieved through the following technical solutions: a kind of pneumatic valve, comprise the valve body be made up of two hemispherical shells, tubular conduit is provided with in the middle part of described valve body, described passage two ends are provided with flanged ends, plastic pipe is provided with in described passage, the seal ring be all tightly connected with passage and plastic pipe is provided with in described passage, described valve body is provided with suction tude and outlet pipe perpendicular to the sidewall of passage, described valve interior wall is provided with annular projection, described annular projection thickness is 6mm, and described suction tude and outlet pipe are provided with pressure gauge.
As present invention further optimization scheme, described plastic pipe two ends are provided with flange plate.
As present invention further optimization scheme, described plastic pipe material is poly-propionitrile, and thickness is 3mm.
As present invention further optimization scheme, described plastic pipe inner and outer surface is all coated with tungsten carbide metal layer.
As present invention further optimization scheme, in described suction tude and outlet pipe, be separately installed with control valve.
Compared with prior art, the present invention has following beneficial effect:
Pneumatic valve of the present invention, described tubular conduit can connection plastic sebific duct, rise and support and leading role, described plastic pipe quality is soft, can comparatively fast shrink until closed when external pressurized, closed thoroughly and fast response time, described seal ring can keep being tightly connected between passage and plastic pipe, the gas to valve body pressurization can be avoided excessive, described suction tude and outlet pipe are respectively used to add gas and venting body to valve body, described annular projection reduces valve interior wall to plastic pipe spacing, thus increase the active force of per unit volume gas, effectively can improve the speed of response that plastic pipe shrinks, described pressure gauge can show the force value of gas, thus ensure the validity that valve body controls, described plastic pipe two ends are provided with flange plate, the connection of convenience and passage two ends flange plate, reaction force can be provided to fix when plastic pipe shrinks, reliability is high, described plastic pipe material is poly-propionitrile, ensure that plastic pipe has during sufficient intensity and has good toughness, described plastic pipe inner and outer surface is all coated with layers of chrome, corrosion resistance and the oxidative stability of plastic pipe can be strengthened, extend the working life of plastic pipe, control valve is separately installed with in described suction tude and outlet pipe, the convenient break-make controlling suction tude and outlet pipe.
