Description
Technical field
The present invention relates to a kind of heavy caliber piston type regulating valve, especially a kind of valve shaft of heavy caliber piston type regulating valve with
The auxiliary guiding of device for driving valve body and spool between spool, supporting device.
Background technique
Regulating valve is used to adjust the flow or pressure of fluid media (medium) in pipeline.Piston type is commonly used in large diameter pipeline to adjust
The flow or pressure of valve regulation fluids within pipes medium.
Heavy caliber piston type regulating valve has drum type brake valve body, and there is water inlet in the front end of valve body, and there is water outlet in the rear end of valve body,
There is valve seal ring in valve body water outlet, the connected drum-shaped spool guide cylinder of useful uniformly distributed radial wing plate, spool in valve body
On the same line, the front end bucket bottom of spool guide cylinder is streamlined to the axis of guide cylinder and valve body, the circle in spool guide cylinder
It is uniformly distributed with axially directed band on cylinder along the circumference, wing plate extends rearwardly to form the axially directed band of back segment, what axially directed band surrounded
Cylindrical space has can be along the drum-shaped spool in axial sliding of spool guide cylinder, and the rear end bucket bottom outside of spool be embedded with and valve body
The seal spool ring that sealing ring matches, valve body are inserted with the valve shaft perpendicular with valve axis, there is spool between valve shaft and spool
Driving device.
In the prior art, the device for driving valve body between the valve shaft and spool of heavy caliber piston type regulating valve is crank connecting link
Mechanism.
In use, driving valve shaft rotation, valve shaft rotation drive spool axially to slide in spool guide cylinder by crank connecting link
It is dynamic, pass through the pipeline rate-of flow or pressure after the circulation area control valve between change seal spool ring and valve seal ring
Power.
This heavy caliber piston type regulating valve is axial in spool guide cylinder with crank connecting link driving device driving spool
When sliding, spool is both by axial force, also by radial force, due to being to be slidably matched between spool guide cylinder and spool, radial force
Sliding axially for spool can be made to generate card resistance phenomenon, card resistance phenomenon not only increases the unpredictable of heavy caliber piston type regulating valve
Switch torque, can also make the abrasion generated between the face of being slidably matched increase, the surface wear that is slidably matched cause spool guide cylinder with
The axis runout of spool reduces the service performance of heavy caliber piston type regulating valve.
The spool of heavy caliber piston type regulating valve is relatively heavy, and uniformly distributed axially directed band had both undertaken in spool guide cylinder
Spool weight is also spool axial direction motion guide, in fact, undertaking bottom semicircular week in the only spool guide cylinder of spool weight
Several axially directed bands in range do not have an aiding support to the weight of spool, and spool is when being axially moved, because spool is downward
Gravity can generate abrasion to the face of being slidably matched of several axially directed bands within the scope of bottom semicircular week in spool guide cylinder, lead
It causes drum-shaped spool to sink, causes the axis of the axis runout spool guide cylinder of drum-shaped spool, influence heavy caliber piston type tune
Save the use of valve.
Summary of the invention
The purpose of the invention is to overcome above-mentioned deficiency, propose a kind of driving device spool will not be made by radial force and
Heavy caliber piston type regulating valve with spool weight secondary support means.
The present invention is achieved using the following method.
Heavy caliber piston type regulating valve has cylinder valve, and there is water inlet in the front end of valve body, and there is water outlet in the rear end of valve body,
There is valve seal ring in valve body water outlet, the connected drum-shaped spool guide cylinder of useful uniformly distributed radial wing plate, spool in valve body
On the same line, the front end bucket bottom of spool guide cylinder is streamlined to the axis of guide cylinder and valve body, the circle in spool guide cylinder
It is uniformly distributed with axially directed band on cylinder along the circumference, wing plate extends rearwardly to form the axially directed band of back segment, what axially directed band surrounded
Cylindrical space has can be along the drum-shaped spool in axial sliding of spool guide cylinder, and the rear end bucket bottom outside of spool be embedded with and valve body
The seal spool ring that sealing ring matches, valve body are inserted with the valve shaft perpendicular with valve axis, there is spool between valve shaft and spool
Driving device,
Device for driving valve body between valve shaft and spool is driven by the combined type that speed-changing gear box and bolt and nut transmission form
Dynamic device, the speed-changing gear box of combined drive are positioningly connected in spool guide cylinder inner wall, and speed-changing gear box is connected in valve
Input terminal and the output end vertical with input terminal valve shaft on axis, output end are connected with bolt and nut transmission, bolt and nut transmission
On the same line, the nut of bolt and nut transmission is positioningly connected on spool secondary screw axis and valve core axis,
Leading portion in spool guide cylinder is positioningly connected with the annulus of the axis of axis and spool guide cylinder on the same line, annulus
On be circumferentially positioningly evenly equipped with the axis cylindrical guide bars parallel with the axis of spool guide cylinder, leading portion in spool is along circle
Week is positioningly evenly equipped with the axle sleeve matched with guide rod, and guide rod is inserted in corresponding axle sleeve.
When installation, heavy caliber piston type regulating valve is mounted on the centre or end of the conveyance conduit of fluid media (medium).
In use, being rotated with the actuator driven valve shaft outside valve, pass through the bolt and nut of speed-changing gear box output end
Driving spool slides axially in spool guide cylinder, adjusts the flow or pressure by water in piston type regulating valve.
What the driving device between valve shaft and spool of the invention was made of speed-changing gear box and bolt and nut transmission
Combined drive, combined drive driving spool is in spool guide cylinder when sliding axially, will not make spool by
Radial force；Uniformly distributed spool guide rod is inserted in the corresponding axle sleeve being evenly arranged in spool in spool guide cylinder, and spool is in spool
When sliding axially in guide cylinder, spool guide rod had both been spool axial direction motion guide or the weight that can undertake spool, moreover it is possible to be prevented
The rotation that spool is generated by the driving of bolt and nut, when spool being made to slide axially in spool guide cylinder, existing spool guiding
Several axially directed bands in cylinder within the scope of the semi-circumference of lower section undertake the weight of spool, also have uniformly distributed spool guide rod to undertake valve
The weight of core, aiding support and guiding device of the spool guide rod as spool weight, dramatically reduces in spool guide cylinder
