Description
Technical field
The utility model relates to modulating valve, particularly relates to Pneumatic straight stroke sleeve control valve.
Background technique
Modulating valve is also known as control valve, and it is the device removing to change rate-of flow in process control system with power operation.The control valve complex structure of prior art, poor sealing performance, spool (i.e. flap) Long-Time Service easily damages, the design of its valve body inner flow passage is unreasonable, cause sealing difficulty to strengthen, and the pressure that spool is subject to also increases, thus affect working life, also more harsh to seal request, have much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure simple, good sealing effect, the Pneumatic straight stroke sleeve control valve of long service life.
For realizing the utility model object, provide following technological scheme: Pneumatic straight stroke sleeve control valve, comprise valve body, the valve gap of valve body upper end, be arranged at the valve rod in valve body, valve stem end is provided with flap, the pneumatic actuator of the valve rod connection valve side of covering, it is characterized in that body cavity is set to staggered floor conducting structure, comprise left side curved channel, center vertical flap chamber and right side curved channel, it is high that left side curved channel is positioned at formation mistake below the curved channel of right side, left side curved channel is communicated with bottom, center vertical flap chamber, right side curved channel is communicated with center vertical flap chamber right openings, left side curved channel length is the twice of right side curved channel, described flap is positioned at center vertical flap chamber, be equipped with bottom, center vertical flap chamber, bottom, center vertical flap chamber inwall is provided with valve seat, center vertical flap chamber end sealing connects valve gap, valve rod is fixedly connected with pneumatic actuator through bonnet central through hole, pneumatic actuator controls valve rod upper and lower displacement, thus the opening and closing of control valve body, flap is plunger shape, the valve cage of internal diameter and flap major diameter fit is provided with in center vertical flap chamber, valve cage nearly lower end sidewall offers the through hole be communicated with right side curved channel.
As preferably, between bonnet central through hole and valve rod, be provided with stuffing seal, the Gland that described stuffing seal comprises filler group and is arranged in filler group.
As preferably, valve gap bottom is provided with center guide hole, and central guiding bore dia is greater than central through bore 1/3.
As preferably, valve gap nearly lower end sidewall is provided with a circle flange, and on flange, cover has adpting flange, and adpting flange is fixedly connected with the top, center vertical flap chamber of valve body by bolt.
The utility model beneficial effect: the utility model, by the appropriate design to valve flowing channel, greatly reduces seal request, and improves the working life of flap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
