The new globe valve---2009-11-06
1, an overview of
At present, the country most of the globe valve hand-wheel or electric device drivers. The hand-wheel-drive globe valve is open or closed, slow, labor-intensive, low degree of automation is not conducive to integrated control valve, and easy to create due to misoperation caused by security incidents. Using ordinary electrical device to open and close the valve, the body a huge energy consumption and large, high cost, used in oil or chemical inflammable fluid tube on the road, the inconvenience to the maintenance and the existence of hidden danger of accidents. Therefore developed a new type of pilot valve with a globe valve. The valve can achieve the basic functions of normal globe valve with a flexible operation, labor-saving, high precision and quick movements, not rust, easy to install, long life and convenient maintenance and so on.
2, valve structure
The globe valve with a pilot valve with manual control and electric control types. Manual globe valve with a pilot valve (Figure 1) from valve body, valve flap, valve cover, orientation kits, seals, springs and diversion pipe component parts. Flap valve was straight cylindrical shape, the bottom of bottom outlet flap valves, valve body with the lower part of the sewage hole, the hole sealed nut installed. Bottom flap valve aperture diameter smaller than the diversion pipe, valves, flap top with pressure ring.
The globe valve with a pilot valve without hand-wheel, stem, and inside the lift nut will be driven into guide blocks and guide groove sets, will be replaced by disk-shaped valve flap valve flap type bowl shape, and in the bottom of the valve flap to open holes, the valve cover of the original stem holes into diversion holes, due to increased pressure ring, ring, and will be replaced by class bowl flap valve body, so that the flow passage of the separation chamber cavity, external cavity, cavity, in the cavity and external cavity with the external plus diversion pipe and stainless steel manual ball valve, flap valve in the cover plate and the center of the end of installing springs, valve flap seals the upper part of an additional compaction of the pressure ring, the outer walls of the cavity opening there are drainage holes. The deadline for the electric control valve, only the pilot-controlled manual ball valve with 3 ~ 5V DC motor drive can be.
