Background technique
Ultrahigh temperature flat gate valve is that a kind of closure member is the slide-valve of parallel gate plate, at present, is mainly used in the transfer line such as rock gas, oil, chemical industry, urban duct, on the device of blowdown system, as opening and closing device.
Existing gate valve structure is simple, design unreasonable, in the process of valve closing, flashboard can produce water level translation, makes flashboard front cover surrounding unbalance stress, can not guarantee that two flashboards put in place simultaneously, it is unreliable to seal, and sealability is bad, bears high temperature capabilities poor, had a strong impact on the working life of valve, and processed complex, cost is high, and the valve opening and closing time is longer, during keying, friction relatively between sealing surface, easily causes scratch.
Summary of the invention
The present invention has overcome the deficiency that prior art exists, and provides a kind of simple and compact for structure, and volume is little, lightweight, and when valve closing, flashboard sealing surface is stressed more even, seals reliable ultrahigh temperature flat gate valve.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: ultrahigh temperature flat gate valve, comprise valve body, bonnet, bottom flange and valve rod, valve body is arranged between bonnet and bottom flange, and valve body and bonnet, bottom flange is all fixedly connected with, the inside of described valve body is provided with flashboard assembly and flashboard fixing frame, described flashboard assembly comprises interior flashboard and outer flashboard, described interior flashboard is movably arranged on the inside of outer flashboard, described outer flashboard is fixedly installed on flashboard fixing frame, the inside of described interior flashboard is provided with steel ball, described valve rod can relatively rotate 90 ° and be installed in valve body by driving, described steel ball is fixedly connected with valve rod, to drive steel ball to rotate in valve body by valve rod, thereby realize the keying of valve.
Described interior flashboard comprises left inside flashboard and right inside flashboard, and described outer flashboard comprises left inside flashboard and right outside flashboard, between described left inside flashboard and left inside flashboard, be inclined-plane between right inside flashboard and right outside flashboard and coordinate.
The two ends at described left inside flashboard and right inside flashboard top are provided with projection, the chute of the section constitution spill of two described projections, and described chute and valve rod are suitable, and the top of described projection is provided with limiting stopper.
On described slide bar, be provided with adjustment block, on the slide bar between described adjustment block and limiting stopper, be set with spring.
The beneficial effect that the present invention compared with prior art has is: the present invention arranges steel ball at inner brake intralamellar part, make fluid resistance little, sealing surface is subject to washing away of medium and corrodes little, valve opening is stronger, good seal performance, MEDIA FLOW is to unrestricted, rope flow not, not step-down power, body is simple, anufacturability is good, using scope is wide, it is less that front cover opens and closes required moment, the present invention adopts the science design of full-closed structure, there is stronger barrier propterty, adapt to round-the-clock requirement, especially high temperature resistant, employing carries the filling-material structure of sealability, without frequent adjusting, open, close very light, and sealing is reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is structural representation of the present invention.
In figure, 1 is that valve body, 2 is that bonnet, 3 is that bottom flange, 4 is that flashboard assembly, 5 is that interior flashboard, 6 is that outer flashboard, 7 is that valve rod, 8 is that flashboard fixing frame, 9 is that steel ball, 10 is spring.
