Description
Technical field
The present invention relates to a kind of corrosion-resistant plug valve, it is mainly used in diesel engine, belongs to valve technology field.
Background technology
Diesel engine is burning diesel oil to obtain exergonic engine, it has the thermal efficiency and better economy,
Diesel engine improves air themperature using the method for compressed air, air themperature is exceeded the self-ignition point of diesel oil, at this moment sprays into again
Oneself ignition while diesel oil, diesel spray and air mix.Therefore, diesel engine is without ignition system.Meanwhile bavin
The oil supply system of oil machine is also relatively easy, therefore the reliability of diesel engine is better than petrol engine.Due to from quick-fried
The limitation of combustion and the needs of diesel oil spontaneous combustion, diesel engine compression ratio are very high.The thermal efficiency and economy will be better than gasoline engine, at the same time
In the case of equal-wattage, the moment of torsion of diesel engine is big, and rotating speed during maximum power is low, is suitable for the use of cargo vehicle.
Equipped with many valves come the diesel oil that circulates in diesel engine, wherein plug valve is a kind of straight-through valve of high-speed switch, by
Movement carries wiping action between sealing surface is revolved, and the contact with flow media can be entirely prevented in standard-sized sheet, therefore it is usual
It can be used for the medium with suspended particulate.Another key property of plug valve is that it is readily adapted to accommodate multi-channel structure, so that one
A valve can obtain two, three, or even four different runners.The design of pipe-line system can so be simplified, reduce valve
Some the connection accessories needed in dosage and equipment.
But when needing repairing after conventional plug valve long-time use, it is necessary to by the handle in valve body, spiral cover, valve seat etc.
All disassemble and could place under repair to valve inner, but since valve seat is fixed in valve body, it is impossible to online detachable maintaining, drop
Low maintenance efficiency；The sealing effect of conventional plug valve is poor at the same time, and cock easily loosens.
The content of the invention
The invention reside in overcome above-mentioned deficiency, there is provided convenient for disassembly and assembly, sealing effect is good, while the steady corrosion resistant of cock
Lose plug valve.
The object of the present invention is achieved like this：
A kind of corrosion-resistant plug valve, it includes valve body, and the centre of the valve body is provided with valve seat, is between the valve seat and valve body
Split type setting, is equipped with cock in the intermediate throughholes of the valve seat, and in the top of cock sealing ring between cock and valve body
Locking backing plate is additionally provided with, the top of the valve body is connected by screw thread with spiral cover, the top of spiral cover and the handle laterally set
It is hinged, spiral cover is rotated by handle, corrosion-resistant finishes is equipped with outside the valve body and valve seat.
The beneficial effects of the invention are as follows：
This corrosion-resistant plug valve, its valve seat and valve body are movable connection, when it is time for repair can be by valve seat and cock one
It is convenient for disassembly and assembly with dismounting, improve maintenance efficiency；Rotation is provided between valve seat and valve body, and between cock and valve body at the same time
Plug sealing ring and filler, its leakproofness is preferable, and high-low pressure can leakproof.
Brief description of the drawings
Fig. 1 is the structure diagram of the corrosion-resistant plug valve of the present invention.
Wherein：Valve body 1, valve seat 2, valve seat gasket ring 3, valve seat insert 4, cock 5, cock sealing ring 6, spiral cover 7, handle 8.
Embodiment
Referring to Fig. 1, the present invention relates to a kind of corrosion-resistant plug valve, including valve body 1, the centre of the valve body 1 is provided with valve
Seat 2, is split type setting between the valve seat 2 and valve body 1, valve seat gasket ring 3 and valve is provided between the valve seat 2 and valve body 1
Seat sealing ring 4, is equipped with cock 5 in the intermediate throughholes of the valve seat 2, cock sealing ring 6 is equipped between the cock 5 and valve body 1,
The top of the valve body 1 is connected by screw thread with spiral cover 7, and the top of spiral cover 7 and the handle 8 laterally set are hinged, pass through handle 8
To rotate spiral cover 7, the outside of valve body 1 and valve seat 2 is equipped with corrosion-resistant finishes, can prevent plug valve from corroding, improving it makes
Use the service life.
This corrosion-resistant plug valve, its valve seat and valve body are movable connection, when it is time for repair can be by valve seat and rotation
Plug is together dismantled, convenient for disassembly and assembly, improves maintenance efficiency；At the same time between valve seat and valve body, and set between cock and valve body
There are cock sealing ring and filler, its leakproofness is preferable, and high-low pressure can leakproof.
