Abstract
A one-way pneumatic diaphragm control valve device comprises an upper diaphragm cover, a spring set, a diaphragm, a lower diaphragm cover, an upper shell body, a support stand column, a valve rod, a valve core, a valve seat, a valve body and a one-way valve diaphragm, wherein the valve seat is arranged in the middle of the valve body, the one-way valve diaphragm is arranged in a center hole of the valve seat, the upper shell body is connected with the middle of the upper portion of the valve body through the support stand column, the lower diaphragm cover is arranged in the upper shell body, the diaphragm is arranged above the lower diaphragm cover, the upper diaphragm is arranged above the diaphragm, the spring set is arranged in an upper shell body inner cavity below the lower diaphragm cover, the upper end of the valve rod penetrates through the lower diaphragm cover and the diaphragm, the lower end of the valve rod extends downwards into the valve body and reaches above the valve seat, and the valve core is connected with the lower end of the valve rod. The one-way pneumatic diaphragm control valve device is simple in whole structure, convenient to operate and use, good in stability, and high in reliability. According to the one-way pneumatic diaphragm control valve device, the discharge coefficient can be increased greatly.
Description
Technical field
The utility model relates to the control valve device, relates in particular to a kind of one-way fashion pneumatic diaphragm control valve device.
Background technique
The pneumatic membrane modulating valve of prior art belongs to mature technology, has easy to use and explosion-proof performance, flow coefficient is an important parameter of pneumatic membrane modulating valve, but the valve body resistance of the pneumatic membrane modulating valve of prior art is large, exist sectional area that rapid variation is arranged on the flow path designs, so that the corresponding increase of local resistance that fluid produces during by valve body, and cavity arranged in the valve body, will certainly produce eddy current because of the effect of cavity, because eddy current causes resistance, thereby caused the reduction of flow coefficient, and therefore affected the practical effect on the pipeline.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of one-way fashion pneumatic diaphragm control valve device is provided, and compact overall structure is lightweight, preferably the augmented flow coefficient.
A kind of one-way fashion pneumatic diaphragm control valve device described in the utility model includes membrane cover, cluster spring, diaphragm, lower membrane cover, upper shell, bracket upright post, valve rod, spool, valve seat, valve body and one-way valve diaphragm.Valve body is the main component of a kind of one-way fashion pneumatic diaphragm control valve device described in the utility model, and the two ends of valve body are set to dock the flange of usefulness, and the middle position at valve body is provided with valve seat, is provided with the one-way valve diaphragm in the center hole of valve seat.Position placed in the middle on valve body is connected with upper shell by bracket upright post, is provided with lower membrane cover in upper shell, on lower membrane cover, be provided with diaphragm, membrane cover on being provided with on diaphragm in the upper shell inner chamber below lower membrane cover, is provided with cluster spring.Lower membrane cover and diaphragm are passed in the upper end of valve rod, and the lower end of valve rod extends downwardly in the valve body, arrive the top of valve seat.Lower end at valve rod is connected with spool.
A kind of one-way fashion pneumatic diaphragm control valve device described in the utility model, overall structure is simple, and is easy for operation, good stability, reliability is high.Use a kind of one-way fashion pneumatic diaphragm control valve device described in the utility model, its compact overall structure that is particularly useful, lightweight, augmented flow coefficient preferably.
