Abstract
The invention discloses a pneumatic straight-stroke sleeve control valve. The pneumatic straight-stroke sleeve control valve comprises a valve body, a valve deck at the upper end of the valve body and a valve rod arranged in the valve body. A valve clack is arranged at the tail end of the valve rod. The valve rod is connected with a pneumatic execution mechanism above the valve deck. A valve body inner cavity is of a staggered layer communicating structure and comprises a left side arc channel, a central vertical valve clack cavity and a right side arc channel. The left side arc channel is arranged under the right side arc channel to form staggered height. The left side arc channel is communicated with the bottom end of the central vertical valve clack cavity. The right side arc channel is communicated with a right side opening of the central vertical valve clack cavity. The length of the left side arc channel is two times that of the right side arc channel. The valve clack is located in the central vertical valve clack cavity and arranged to be matched with the bottom end of the central vertical valve clack cavity. A valve seat is arranged on the inner wall of the bottom end of the central vertical valve clack cavity. The top end of the central vertical valve clack cavity is in sealing connection with the valve deck. The valve clack is in a shape of a cylindrical piston. A valve cage of which inner diameter is matched with the outer diameter of the valve clack is arranged in the central vertical valve clack cavity. Through holes communicated with the right side arc channel are formed in the side wall, close to the lower end, of the valve cage.
Description
Technical field
The present invention relates to modulating valve, particularly relate 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 present invention is directed to the deficiencies in the prior art, provide a kind of structure simple, good sealing effect, the Pneumatic straight stroke sleeve control valve of long service life.
For realizing the object of the invention, 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.
Beneficial effect of the present invention: the present invention, 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 invention.
