Abstract
The utility model relates to a plate type gate valve for cinder and particle material, comprising a valve body, a valve plate, a fixing valve seat, a floating valve seat, springs, a sealing ring, a valve seat sleeve, a valve rod, etc. The front end of the valve plate is a single side wedge body which is used as a self-clearing device for the cinder of the valve, and the solid material deposited in the intracavity of the valve body can be self-cleared at the time of the opening and closing of the valve plate. A plurality of O-shaped sealing rings or piston ring-shaped metal sealing rings made of the elastic alloy which is tolerant to heat and corrosion are arranged on the floating valve seat. The space between the floating valve seat and the valve sleeve is sealed to prevent the solid material in gas-solid medium going into the intracavity of the valve body. Below or at the temperature of 750 DEG C, the utility model can work for a long time steadily and safely.
Description
Be used for lime-ash, the plate valve of powder medium relates to the manufacturing technology of valve, is applicable to the occasion of lime-ash in room temperature or the hot environment, powder MEDIA FLOW.
The plate valve that is used for lime-ash, powder medium, in closing closed procedure, valve plate can take ducted solid material to body cavity and deposit, if do not get rid of these depositions solid material could proper functioning; Particularly at the lime-ash of hot environment, the valve of powder MEDIA FLOW work.Domestic product-free still and relevant report abroad also are not used in greater than 450 ℃ of reports less than 750 ℃ gas one solid media plate gate valve at present.
The purpose of this utility model is a kind of plate valve that is used for lime-ash, powder gas-solid MEDIA FLOW of design, this gate valve open-close convenient, existing regular slag extractor, the device that automatic removing lime-ash is arranged again, the valve base sealing function admirable can be worked under the environment of high temperature (being lower than 750 ℃) again long-term and stably in room temperature.
The utility model is achieved in that adopting front end is the single face wedge, and round-meshed sheet metal is as valve plate, and wedge point place angle is 15 °～30 °.Valve plate closely is installed between fixed valve base and the floating valve seat, in the course of the work, in the solid material of deposition enters circular hole on the valve plate along the wedge of valve plate front end automatically, and be clipped between fixed valve base and the floating valve seat, and then bring back in the pipeline by valve plate, the solid material in the inaccessible place of wedge can be regularly by fixedly ash discharge slag device eliminating; Some roads seal ring is set on floating valve seat, enters valve insertion by the valve seat gap to stop the solid dielectric in the gas one solid medium.When the utility model was worked under≤200 ℃ of temperature, seal ring adopted " O " type rubber ring, adopted by high temperature resistant in the time of 200 ℃～750 ℃, and the shape corrosion-resistant, that elastic alloy is made such as the metal ring of piston ring are as seal ring.
The novel advantage of this employing is:
1, the utility model is simple in structure, and valve plate, the surface of contact of valve seat all are the planes, and processing and fabricating and reparation are convenient, the thermal distortion of the displacement energy of floating valve seat compensation part, and the end of valve plate is free end varies with temperature and stretches, therefore, the hot adaptability of valve is good, is applicable to the high temperature occasion.
2, the valve plate front end is made the single face wedge, by this wedge, just can bring back to the solid dielectric that is deposited in valve insertion in the pipeline medium stream in the course of the work and go, make the valve plate edge work, the solid material that is deposited on inner chamber is removed on the limit automatically, has overcome the shortcoming that hinders the gate valve proper functioning owing to inner chamber accumulated solids medium too much.
3, the utility model is provided with three roads with heat-resisting at floating valve seat, and anti-corrosion, elastic alloy is made the seal ring of shape such as piston ring, can stop solid dielectric to enter body cavity by the gap of floating valve seat and valve seat inner room effectively.The heating resisting metal seal ring processing of this piston ring type is more convenient, also is convenient to mounting or dismounting.
Accompanying drawing is the coal lock that the utility model is used for the coal gas fluidized-bed gasification furnace, the ash lock, and the embodiment of dipleg, wherein;
Fig. 1 plate valve structural drawing;
Fig. 2 removes lime-ash and floating valve seat sealing schematic representation automatically;
Now the utility model will be further described in conjunction with the accompanying drawings,
Fig. 1, plate valve structural drawing.The utility model is by valve body 1, valve plate 2, and fixed valve base 3, floating valve seat 4, spring 5, valve seat cover 6, seal ring 7, valve rod 8, ash discharge plug screw 9 constitutes.
The front end of valve plate 2 is one and half wedges, wedge point place angle is 15 ° of-30 ° of automatic dust-removing devices of conduct, there is a port hole at the middle part, its diameter is with the channel diameter in the valve body 1, the rear end links to each other with valve rod 8, fixed valve base 3 is a cylindrical body, and the internal diameter of tube is consistent with the diameter in valve plate upper channel hole, and fixed valve base 3 is fixedly mounted on the side in the valve body 1.On the top of floating valve seat 4 flange is arranged, on flange, have the hole of several device springs 5, the endoporus of floating valve seat 4 is stepped shaft, the big hole diameter is with the diameter in hole on the valve plate 2, the small sircle hole diameter is slightly smaller than the big hole diameter, and if the floating valve seat external cylindrical surface is provided with the groove of three duct device seal rings 7.When the utility model be in＜when working under 200 ℃ of temperature, seal ring 7 adopts " O " type rubber seal, when working under 200 ℃～750 ℃ temperature, seal ring 7 adopts by heat-resisting, corrosion-resistant, and the shape that elastic alloy is made such as the metal ring of piston ring are as seal ring.Valve seat cover 6 is sleeves that have flange.The opposite side that valve seat cover 6 is fixedly mounted in the valve body 1, floating valve seat 4 are sleeved in the valve seat cover 6 versatilely.Valve plate 2 is installed between fixed valve base 3 and the floating valve seat 4, and floating valve seat 4 closely contacts, forms sealing surface with valve plate 2, fixed valve base 3 under the effect of spring 5.At valve plate 2, on the surface of contact of fixed valve base 3, floating valve seat 4 built-up welding heat-resisting, high-abrasive material.Be equipped with ash discharge plug screw 9 in the bottom of valve body 1, eliminating regularly is deposited on the endoceliac solid material of valve.
In the utility model working procedure, valve plate 2 is subjected to valve rod 8 to drive moving back and forth with opening/shutting valve at fixed valve base 3 and floating valve seat 4, at this simultaneously, the single face wedge of valve plate 2 front ends also inserts in the valve body thereupon, the lime-ash, powder solid material of deposition then moves and enters in the hole on the valve plate 2 along valve plate 2 front end inclined-planes, and when valve plate 2 is return, the solid material in the hole will be brought back in the pipeline, the energy edge work, lime-ash, the powder solid material 10(Fig. 2 that deposits in the inner chamber removed on the limit automatically).For wedge shovel less than and remain in solid thing material in the valve body, can be regularly by ash discharge plug screw 9 with its emptying.In the outer wall groove of the bottom of floating valve seat 4, be provided with the metal ring seal ring 7 of shape such as piston ring, stoped solid material to enter body cavity effectively, reduced the deposition of body cavity solid material by the gap of 6 in floating valve seat 4 and valve seat cover.
