The inner surfaces of the valve chamber are all provided with anti-corrosion layers and ultrahigh molecular weight polyethylene anti-scale and abrasion resistance layers. The utility model is suitable for the transporting technology of ash and water power of a thermal power plant and is suitable for the frequent throttling and startstop environment of the slurry media with strong cavitation-corrosion performance, strong abrasion performance, strong scale performance, strong shock performance, strong corrosion performance and super high solid content in the electric power industry, metallurgy industry, nonferrous metal industry, coal industry, chemical industry, mine industry, environmental protection industry, etc.
Description
Technical field
The utility model patent relates to valve, is a kind ofly to be under the bad working environments that cavitation corrosion, abrasion, fouling, burn into impact in the solid-liquid slurry medium, can make throttling arrangement, can make the multi-functional steel of start-stop device again and mould compound gate valve.
Background technique
The solid-liquid slurry that is strong cavitation corrosion, abrasion, fouling, burn into impact at medium is carried bad working environments, and gate valve is under the frequent throttling of fed sheet of a media, keying alternating action, and valve body, valve seat and flashboard cavitation corrosion, abrasion are seriously; And between valve body and the flashboard position guiding groove and position fouling such as valve neck, cause the valve opening and closing difficulty.Existing opening and closing gate valve can not throttling, and the throttling gate valve can't be closed, and can only supportingly use.And certain Single disc throttling opens and closes valve, and for example ceramic throttling gate valve is that the flashboard bottom becomes door opening (circular arc) shape to make throttling arrangement, and start-stop device is made for whole flashboard in flashboard top.The dark concave portion of body cavity bottom and door opening shape flashboard are formed slick and sly passage, to regulate flow and to store the flashboard that descends.Operation facts have proved: the slurry of Liu Donging is under door opening shape flashboard throttling action rapidly, dark pit of valve body and flashboard place produce strong cavitation corrosion, abrasion, vortex and impact, when the flashboard quick closedown, produce strong impact of water hammer, rigidity pottery flashboard and lining be easily cracked, come off, and the valve wearing and tearing are very fast.Simultaneously, the dark pit of valve body easily deposits lime-ash, and flashboard can't end, close, and causes valve to decline to a great extent working life, is difficult to reach designing requirement, can't guarantee system safety operation.
The model utility content
The purpose of this utility model is at the problems referred to above, and provide a kind of under strong cavitation corrosion, strong abrasion, strong fouling tendency and severe corrosive solid-liquid slurry medium operating mode, have good throttling and open and close dual functions, and the effective steel-plastic composite valve of anti-tartar wear-and corrosion-resistant.
The technological scheme that realizes above-mentioned purpose is: a kind of throttling and the gate valve that opens and closes dual functions, it is that the throttling gate valve of routine and the simple function of opening and closing gate valve are united two into one, and forms new compound gate valve.Mariages thick stick drive unit, the elasticity double disc parallel seat structural type of single action is separately adopted in the design of this gate valve.The throttling flashboard of special round hole type and whole monocline face wedge-type open and close flashboard parallel near, connect by leading screw separately parallel to each other respectively, two handwheels of leading screw upper end drive umbrella gear separately and pay the rotation of driving leading screw, and flashboard is upper and lower respectively to be moved, thereby reaches valve throttle or open and close function.During the throttling of throttling flashboard, medium flows through simultaneously from special round hole or from the passage between special round hole and throttling flashboard bottom and valve body, and the basic maintenance flow direction consistent with the runner axis is to reduce fluid resistance and the cavitation corrosion of valve interior wall is worn and torn.Conventional position guiding groove has been cancelled with sliding in the location of valve body and flashboard, and with the location and the slip that are slidingly matched and implement flashboard between flashboard and Cross section Design becomes and the flashboard cross section matches the rectangle valve neck inwall, has eliminated the scale formation between flashboard and valve body.In addition, the polished rod position of leading screw cladding plastics, and installed thrust bearing and fluoroplastic filler significantly reduce frictional force, cause flashboard lifting easy and flexible.
The technical solution of the utility model also comprises: the central passage of valve body is directly more slightly larger than two end flange port holes, forms the scrobicula annular groove, and the toroidal surface of central passage both sides is the flashboard sealing surface.Like this, valve can guarantee that sealing surface and valve body bottom do not deposit lime-ash, opens and closes when flashboard cuts out to completely cut off medium, and in the time of slowing down the operation of throttling flashboard again, medium produces strong cavitation corrosion phenomenon and damages valve body valve.
Multi-functional steel is moulded all and medium contact position such as the metal inner cavity (comprising valve body, valve seat, valve gap) of compound gate valve and leading screw anticorrosive coat all is set, and then the high molecular weight polyethylene board material that resistive connection dirt wear-corrosion resistance corrosion protection excellent shock resistance is set is made the anti-tartar wearing layer.Flashboard adopts whole superelevation PE elastic engineering plastics mold pressing flashboard, and the powerful impact of water hammer energy that produces in the time of effectively absorbing the flashboard quick closedown slows down the destruction to pipeline.The whole anti-tartar wear-and corrosion-resistant function admirable of composite valve.
Description of drawings
Accompanying drawing is the scheme of erection of the utility model valve mechanism.
Embodiment
As accompanying drawing, the utility model valve is that steel is moulded compound gate valve, adopt the surface of valve body 1, valve body, valve seat, valve gap and the leading screw of cast steel moulding that anticorrosive coat 2 all is set at metal valve, and then the anti-tartar wearing layer 3 that is made of the engineering plastics ultra-high molecular weight polyethylene is set, valve body middle aperture 4 is more slightly larger than flange aperture, two ends, become streamlined, to slow down cavitation corrosion and fouling.
The plane round hole type throttling flashboard 5 that integral, flexible engineering plastics ultrahigh molecular weight polyethylene becomes and monocline face wedge-type open and close flashboard 6 parallel near, be installed in the valve neck position of body cavity and the plastic board of valve neck and valve interior wall and make slide displacement.Two handwheels 7 by both sides, valve top are drive transmission 8 (umbrella gear is paid, bearing, axle sleeve) and leading screw rotation separately, makes the throttling flashboard respectively or open and close flashboard direct-axis line reciprocating, finally implements the function of valve throttle or keying.
