Abstract
The invention discloses an insulating gate valve, and belongs to the field of valves. The insulating gate valve comprises a valve body, a gate and a valve rod; the valve body is covered with a layer of insulating jacket, and a water inlet and a water outlet are connected to one side of the insulating jacket by flanges while a movable handle is arranged on the other side; the movable handle is welded to a slider, and a sliding chute matched with the slider is also arranged on the outer wall of the insulating jacket; a semicircular-ring-shaped scraper plate fitting with the valve body is arranged in the insulating jacket, and the scraper plate is connected to the handle; a sewage storage groove is arranged at one end part in the insulating jacket, and a sewage hole is formed in the bottom of the sewage storage groove and an end cap fitting with the sewage hole is also arranged at the bottom of the same. By using the insulating gate valve, the problem about blockage of the insulating jacket is effectively overcome.
Description
Technical field
The present invention relates to valve field, specifically a kind of heat insulation gate valve.
Background technique
Gate valve makes open-shut device with flashboard and move along valve seat axes normal direction, to realize the valve of switching motion.Gate valve can only standard-sized sheet and complete shut-down, and open-shut device is flashboard, moving direction and flow direction perpendicular, square I-shaped gate valve two sealing surfaces form wedge shapes, key groove is different with valve parameter.
In the industrial field such as chemical industry, pharmacy, often can run into high viscosity medium, now need insulation jacket to carry out isothermal holding to gate valve, after avoiding temperature to reduce, medium easily crystallization on flashboard, affects smooth keying and the sealability of flashboard thus.In the prior art, multidirectional insulation jacket leads to the thermal source such as hot water or water vapour, but general insulation jacket only has import and outlet, and mostly is the circulating water containing impurity in industrial water, Long-Time Service can cause incrustation scale in chuck to accumulate, and results in blockage and heat insulation effect variation.
Summary of the invention
The invention provides a kind of heat insulation gate valve, be intended to solve the problem.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of heat insulation gate valve, comprise valve body, flashboard, valve rod, it is characterized in that: described valve body outer wrap has one layer of heat preservation chuck, insulation jacket side is connected with water intake and water outlet with flange, and opposite side is provided with flexible handle; Described flexible handle is welded on draw runner, and the outer wall of insulation jacket is also provided with the slideway with draw runner adaptation; Be provided with the semi-circular shape scraping blade of fitting with valve body in described insulation jacket, scraping blade is connected to handle; End, one end in described insulation jacket is provided with sewage-storage trough, has pollutant exhaust hole bottom sewage-storage trough, and is provided with the plug with pollutant exhaust hole adaptation.
Further, the opening of described slideway is provided with limited step.
Further, described plug has the annular groove placing seal ring.
Beneficial effect of the present invention is: after adopting insulation jacket, gate valve can effectively be used in the industrial field of high viscosity medium, avoids temperature to reduce and causes medium crystallization, sticks on flashboard and makes ram seal lose efficacy and open and close malfunctioning.In insulation jacket, arrange the semi-circular shape scraping blade of fitting with valve body, can effectively strike off in Long-Time Service, the incrustation scale that what hot water or water vapor brought be attached on valve body wall or other impurity, avoid the blocking of insulation jacket.Drive scraping blade and draw runner to move in slideway with flexible handle, structure is simple, processing ease.Be provided with sewage-storage trough in one end of insulation jacket, the incrustation scale that effective accumulation is struck off at every turn, after certain number of times, then got rid of by pollutant exhaust hole, structure is simple, realizes the cleanablity energy of insulation jacket.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat insulation gate valve provided by the invention.
Mark in figure: 1 be valve body, 2 be flexible handle, 3 be slideway, 4 be scraping blade, 5 be insulation jacket, 6 be valve rod, 7 be flashboard, 8 be valve seat, 9 be plug, 10 be annular groove, 11 be sewage-storage trough, 12 for draw runner.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of heat insulation gate valve, comprises valve body 1, flashboard 7, valve rod 6, and described valve body 1 outer wrap has one layer of heat preservation chuck 5, and insulation jacket 5 side is connected with water intake and water outlet with flange, and opposite side is provided with flexible handle 2; Described flexible handle 2 is welded on draw runner 12, and the outer wall of insulation jacket 5 is also provided with the slideway 3 with draw runner 12 adaptation; Be provided with the semi-circular shape scraping blade 4 of fitting with valve body 1 in described insulation jacket 5, scraping blade 4 is connected to handle 2; End, one end in described insulation jacket 5 is provided with sewage-storage trough 11, has pollutant exhaust hole bottom sewage-storage trough 11, and is provided with the plug 9 with pollutant exhaust hole adaptation.The opening of described slideway 3 is provided with limited step.Described plug 9 has the annular groove placing seal ring.
When gate valve carries out insulation water filling or injects steam, with flexible handle 2, draw runner and scraping blade 4 are maintained static.Inject the thermal source such as hot water or water vapour by water intake and carry out isothermal holding to gate valve, after avoiding temperature to reduce, high viscosity medium is bonded on flashboard 7, causes flashboard 7 and valve seat 8 seal failure.After long-term use, due to recycling of industrial water, water conservancy impurity is more, very easily in insulation jacket 5, forms incrustation scale and foreign matter, causes the heat insulation effect of insulation jacket 5 to reduce, now, drive draw runner 12 and scraping blade 4 mobile in slideway 3 with flexible handle 2, scraping blade 4 is fitted valve body 1, strikes off the incrustation scale be adsorbed on valve body 1 wall, until flexible handle 2 moves to one end of insulation jacket, the incrustation scale struck off and foreign matter are pushed sewage-storage trough 11.After certain number of times, the incrustation scale of sewage-storage trough 11 and foreign matter accumulate a certain amount of, unplug plug 9, are discharged by the foreign material in sewage-storage trough 11 from pollutant exhaust hole.Invention structure is simple, processing ease, effectively can solve the problem of insulation jacket blocking.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
