Technical field
The utility model relates to a kind of eccentric rotary regulating valve be applied on oil, coal chemical engineering equipment, and the utility model especially relates to a kind of full runner bushing pipe camflex valve.
Background technique
Now along with the fast development of China's oil coal industry, also more and more higher to the requirement of industrial process control system.And operating mode reality severe on these devices cannot be avoided, containing solid particle hard in a large number in the media such as such as slurry oil, cinder, Heisui River, buck, these solid particles bring serious abrasion along with the medium of high temperature, high pressure, High Pressure Difference to valve pocket and trim and wash away, simultaneously, the ultra-fine grain of extreme hardness easily enters in the matching gap of valve body and lining, lining and valve rod, valve rod and valve ball, accelerate the failure seal element and director element, cause valve exceed leakage class require or action bite even stuck.
In the face of so harsh operating mode, the technological means taked when designing camflex valve is at present: trim split-type design, increase trim ring bushing pipe, valve seat bushing pipe, sphere, these parts are made by cemented carbide together with the stop collar up and down of spool, carry out washing away directly in the face of medium, body cavity spraying cure process.These means effectively alleviate the leakage and bite problem that occur in valve event process.But, there is matching gap in the trim of kit form, at high temperature, high pressure, easily be out of shape in the environment of High Pressure Difference and solid-liquid two-phase flow, occur loosening, valve event can be made unreliable, degree of regulation is not high, and the spray layer thickness of spraying hardening technique is limited, poor with basal body binding force, easily peeling off is the technical bottleneck of the state of the art objective reality, in actual use, still there is trim and body cavity abrasion is washed away serious, spool comes off, the phenomenons such as valve body perforation, hidden danger is brought to personal safety as well as the property safety, user needs the maintenance of frequent parking checking, change trim, the normal table that have impact on device runs.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of anti-abrasion resistance to erosion, the working life that can extend valve and repair cycle and the full runner bushing pipe camflex valve of enhancing productivity.
According to the technological scheme that the utility model provides, described full runner bushing pipe camflex valve, valve rod is rotatablely equipped with in valve body, valve rod is fixed with upper limit cover and lower limit cover, valve rod between upper limit cover and lower limit overlap is fixed with valve ball, pass on left left trim ring at valve inner and be fixed with valve seat, valve seat coordinates with valve ball, the first gasket seal is provided with between left trim ring and valve seat and between left trim ring and valve body, bushing pipe is fixed with by right trim ring on the right side of valve inner, bushing pipe is provided with for valve rod, upper limit cover with lower limit cover through through hole, the left end of bushing pipe is closely enclosed within the right-hand member outside of valve seat, the second gasket seal is provided with between right trim ring and bushing pipe.
On the left of valve inner, be provided with step in the first location, valve seat is provided with the first location outer step, the first location outer step and first is located interior step and is coordinated, in the first location outer step and first is located, be provided with spacer between step.
On the right side of valve inner, be provided with step in the second location, bushing pipe is provided with the second location outer step, the second location outer step and second is located interior step and is coordinated.
Described first gasket seal and the second gasket seal adopt graphite material to make.
Described valve ball and valve seat all adopt cemented carbide to make.
Described bushing pipe adopts cemented carbide to make.
The utility model has the following advantages:
1, anti-abrasion resistance to erosion ability is strong.Full runner bushing pipe, valve ball and valve seat are made by cemented carbide, more than hardness HRA85, and resistance to erosion ability is strong, can avoid washing away of the not straight accepting medium of body cavity, soft line style runner is gently smooth, and dead band is little, not easily buildup, can ensure that valve working life is more than 18 months.
2, sealing is reliable, and degree of regulation is high.Valve ball and valve seat are integrated type cemented carbide, and machining deformation amount is little, and intensity is high, good rigidly, also effectively can avoid the distortion that temperature difference pressure reduction causes.There will not be in course of action by shaking the loosening phenomenon causing valve regulated precise decreasing and action bite caused.Sealing surface, through grinding disposing, can realize the sealing of valve long-term stability and highi degree of accuracy adjustment.
3, the cost of overhaul is low.When the regular checking maintenance of valve, only need change and the full runner bushing pipe of medium contact, valve ball and valve seat, easy to operate.With changed whole valve ratio in the past, the cost of overhaul reduces greatly, and manufacturing efficiency significantly improves.
