Description
Technical field
The present invention relates to valve field, and plug valve is lifted more particularly to one kind.
Background technology
At present, the design that the lifting type plug valve that has of in the market is separated using lifting with switching manipulation, during valve opening and closing
Need first to rotate lifting device so that valve rises, be then rotated further by the opening and closing that switch realizes valve, finally also need to turn again
Dynamic lifting device causes valve reset, and single opening and closing needs to carry out six actions for changing steering, and it is not especially square to use
Just, there is the space further lifted, in addition, lifting type plug valve in the market can make it that valve seat is complete with cock body in lifting
It is complete to disengage, it is impossible to meet the needs of some specific industry such as coal chemical industries, and use the plug valve of integral structure,
Clean and maintenance during use is cumbersome, frequently results in the problems such as stopping production is rebuild.
A kind of Chinese invention such as entitled " lifting type plug valve " of Patent No. " 201520514319.6 " is special
Profit, disclose a kind of lifting type plug valve.It includes valve body, cock body, lower cover, valve rod, bonnet, gland, underdrive set, limit
Position block, drive link, handwheel, round nut, bearing cap, bearing, rack shell body, guide sleeve, guide roller, upper drive sleeve, front stall
Ring, rear seat ring, spring base, butterfly spring, valve seat insert etc..But the patent is disadvantageous in that：1st, can only grasp manually
Make, it is impossible to apply in automated production process；2nd, cock fixed structure built on the sand, is easily separated from bottom flange；3rd, cock is closed
When, no arcuate zone reduces the contact area between fluid and the installation cavity of cock, and sealing is poor；4th, without filtration facility
Impact of the impurity to cock in fluid is reduced, if things go on like this due to the accumulation of impurity, through flow hole is possible to blocking occur to cause valve
The situation of door failure occurs.
The content of the invention
It is an object of the invention to overcome above mentioned problem existing for prior art, a kind of lifting plug valve is proposed.The present invention
It is simple in construction, it is easily manufactured, using pneumatic control, it may apply in serialization, the production technology of automation, also add
Function is filtered, service life is substantially prolongs, reduces maintenance cost and cost, ensure that the continuous of subsequent technique, is especially promoted
And popularization.
The present invention is realized using following technical scheme：
One kind lifting plug valve, it is characterised in that：Including valve body, cock, bonnet, bottom flange, valve rod, support, pneumatic
Device and hand gear, the cock are arranged in valve body, and the valve body is provided with entrance point and the port of export, and the bonnet, is with
Bonnet is separately mounted to the upper and lower part of valve body, and the support is arranged on bonnet, the cock be provided with it is upper it is raised, under it is convex

Support, bonnet, are stretched into valve body and are fixed in the slot of cock successively for one end, and the bottom flange is provided with holding tank, the rotation
In the lower convexity insertion holding tank of plug, the contact surface of the cock and valve body is provided with pad, the both sides of the cock provided with pair
The arcuate zone of title, the bottom land of the holding tank are provided with magnetic part I, and lower convexity is provided with magnetic part II, lower convexity by magnetic part I with
The magnetic of magnetic part II, which connects, to be fixed in holding tank.
The pad is the pad that stainless steel and soft graphite are combined.
The cock is steel alloy cock.
The cock surface spraying has nickel-base alloy.Nickel-base alloy have under 650~1000 DEG C of high temperature higher intensity with
Certain antioxidant anticorrosive ability etc..
Filter is installed on the entrance point, filter includes filtering head and filtering body, the filtering head be fixed on into
On mouth end, filtering body is stretched into entrance point, and the filtering filters body as hollow out, and the filtering body is interior to be provided with screen pack.
The aperture of the screen pack is 2mm-5mm.
Also include outer cover, the outer cover is fixed on valve body, the outer cover by bonnet, valve rod, support, pneumatic means and
Hand gear seals.
The present invention compared with prior art, the advantage is that：
1st, the present invention is simple in construction, easily manufactured, and pneumatic control is realized using pneumatic means, and can coordinate with controller should
Use in serialization, the production technology of automation, also add filtering function, substantially prolongs service life, reduce maintenance
Expense and cost, the continuous of subsequent technique is ensure that, is especially popularized.
2nd, the present invention use hand gear, can be controlled manually, mode of operation is various, operation side in maintenance and when safeguarding
Just.
3rd, the present invention is provided with symmetrical arcuate zone using the both sides of the cock, and arcuate zone can reduce fluid and cock
Contact area between installation cavity, improve the sealing property of cock.
4th, the present invention is provided with magnetic part I using the bottom land of the holding tank, and lower convexity is provided with magnetic part II, and lower convexity passes through
Magnetic part I connects with the magnetic of magnetic part II and is fixed in holding tank, and magnetic connects the steadiness for adding structure in succession, and magnetic connects mode due to magnetic
The attraction of field can also play a part of guiding.
5th, the present invention uses the cock cock surface spraying has nickel-base alloy, nickel-base alloy for steel alloy cock
There are higher intensity and certain antioxidant anticorrosive ability under 650~1000 DEG C of high temperature, extend the service life of cock.
6th, the present invention includes filtering head and filtering body, the mistake using filter, filter is provided with the entrance point
Filter is fixed on entrance point, and filtering body is stretched into entrance point, and the filtering filters body as hollow out, is provided with the filtering body
Screen pack, the filtering body of hollow out can effectively prevent the larger impurity in aperture from entering in valve body, and screen pack can effectively prevent hole
The smaller particulate in footpath enters in valve body, so as to which the double ball valves of ceramics are effectively protected.
7th, the present invention uses the aperture of the screen pack as 2mm-5mm, can effectively prevent that aperture is miscellaneous more than 2mm-5mm
Matter enters in valve body, protects valve body, extends the service life of ceramic double ball valves.
8th, using also including outer cover, the outer cover is fixed on valve body the present invention, and the outer cover is by bonnet, valve rod, branch
