Description
Technical field
The present invention relates to plug valve fields, more specifically to a kind of fuel gas plug valve.
Background technique
Plug valve is the rotary valve of closure member or plunger shape, by being rotated by 90 ° on the passway and valve body that make on valve plug
Passway is identical or separates, and realizes a kind of valve opened or closed.
Plug valve is to use the cock body with through-hole as the valve of opening and closing element.Cock body is rotated with valve rod, to realize switching motion.
Since movement has wiping action between cock valve sealing surface, and the contact with flow media can be entirely prevented in standard-sized sheet, therefore
It usually 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 a valve can obtain two, three or even four different runners.It can simplify the design of pipe-line system in this way, subtract
The some connection accessories needed in few valve dosage and equipment.In order to expand the application range of plug valve, many is had been developed that
New structure.Lubricant plug valve is most important one kind.Special lubricating grease injects valve body taper hole and cock body from cock body top
Between, oil film is formed to reduce opening and closing torque, improves leakproofness and service life.Its operating pressure is up to 64 megapascal, highest
Operating temperature is up to 325 DEG C, and maximum caliber is up to 600 millimeters.There are many forms in the channel of plug valve.Common through type is main
For fluid to be truncated.Threeway and tubing type plug valve are suitable for fluid reversing.
Plug valve is widely used in oilfield exploitation, conveying and concise equipment, while being also widely used in petrochemical industry, being changed
In work, coal gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.Plug valve can be divided into tightening formula by structure type
Plug valve, self-sealing plug valve, plug valve and four kinds of oil-filling type plug valve.By channel form point, can be divided into through type plug valve,
Three way type plug valve and three kinds of tubing type plug valve, soft sealing plug valve is usually used in corrosivity, severe toxicity and height, and to endanger medium etc. severe
Environment is carved, the stringent occasion for prohibiting leakage and valve material will not form the occasion of pollution to medium.Valve body can be situated between according to work
Matter selects carbon steel, steel alloy and stainless steel material；Oil lubrication seals plug valve firmly can be divided into conventional lubricant plug valve and pressure
Balanced type cock valve.Special lubricating grease between injection valve body taper hole and cock body, forms oil film at the top of cock body to reduce valve
Torque is opened and closed, leakproofness and service life are improved.For its operating pressure up to 64MPa, maximum operating temperature is maximum up to 325 degree
Bore is up to 600mm；There are many structure type, lifting type plug valves to be divided into soft seal by the material of sealing surface for lifting type plug valve
With hard two kinds of sealing.To rise cock when opening when its basic principle, cock is rotated further by 90 degree can subtract to valve wide open process
Few and valve body sealing surface frictional force；Cock is set to rotate 90 degree to declining behind closed position again and valve body sealing surface when closing valve
Contact reaches sealing；
Double containment lifting type plug valve double containment lifting type plug valve is soft sealing structure.Faucet body be three pieces of board groups close and
At cylindrical plug, rubber sealing surface is inlayed on the plate of two sides, centre is cylindrical drift ping.Transmission mechanism makes to revolve when Open valve
It rises beyond the Great Wall, both side plate is driven to collapse, make to combine after cock body and valve sealing face be detached from, then to drive cock body to be rotated by 90 ° valve complete
Open position.Transmission mechanism makes to combine cock body and rotates 90 degree to behind closed position when closing valve, then cock body is pushed to decline, both side plate
It no longer being moved down after being contacted with body base, intermediate drift ping continues to decline, and it is mobile by the promotion both side plate phase entrance end on inclined-plane,
It is compressed after making the soft sealing face of side plate and valve seal face contact and reaches sealing.Double containment lifting type plug valve has double
Obstruction and discharge function, valve are equipped with pressure equaliser, to prevent system exception boosting, and can be reduced valve opening and closing moment
Resistance.Metal covering contacts with each other after being compressed due to sealing ring, and valve has fire-proof function.The maintenance of valve is very convenient, can
In the case where valve body not being dismantled from pipeline, the end cap by dismantling body base can be taken out both side plate more from valve body
It changes.Therefore be also widely used for petroleum, natural gas, metallurgical mine, gas engineering, industry light industry textile industry, ship harbour, food and
The every profession and trades such as environmentally friendly water process, which make adjustments, open and close pipeline fluid is used.
Gas leakage is an extremely dangerous event, in April, 2015 to October, combustion gas caused by Shenyang City constructs because of cruelty
Leakage 56, only generation 5 during " ten once " golden week, causes huge economic loss.August 8 days, Shenyang Hun Nan area was small
A gas mains near area are bored by certain unit in charge of construction to be leaked, and causes 400,000 yuan of direct economic loss, and fortunately discovery in time, does not just have

It is in time and obvious, can effectively helping gas leakage alarm, remind user to take the safety measures such as maintenance in time, be greatly lowered because
Improper use or because installation question generate gas leakage security risk.
The foregoing is intended to be a preferred embodiment of the present invention；But scope of protection of the present invention is not limited thereto.
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
It improves design and is subject to equivalent substitution or change, should be covered by the scope of protection of the present invention.
