Abstract
The utility model relates to an antiwear throttle valve specially adapted for electric power plant, consisting of a valve body, a valve stem, a valve cover, a bracket and a handwheel, wherein, the valve stem and the handwheel are connected with each other through the valve cover and a flashboard inside the valve body; the bracket is arranged under the handwheel; a gland bush is arranged on the valve cover; an antiwear housing is arranged on the valve body; an antiwear channel is formed by the antiwear housing provided with an antiwear slot, an antiwear convex circular arc and an antiwear sealing face; and a sealing accessory structure is formed by the antiwear sealing face and a sealing face of the flashboard. The utility model adopts high wear-resistant materials and has the advantages of simple structure, good sealing performance, flexible switching of the flashboard, convenient operation and maintenances, improved antiwear property of the valve, and prolonged service life.
Description
Technical field
The utility model relates to a kind of power plant special antiwear throttle valve.
Background technique
Domestic thermal power plant ash disposal system throttle valve, its flow passage part (as valve body, flashboard etc.) antiwear property is not good, because the water mortar impacts seriously, long then 1-2 of one deck valve door life-span month, short have only 2-3 week, and valve is changed frequently, and waste economically is very big.
Summary of the invention
At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of power plant special antiwear throttle valve.
The technical solution adopted in the utility model is: a kind of power plant special antiwear throttle valve, be made up of valve body, valve rod, valve gap, support and handwheel, wherein, valve rod and handwheel also are connected with flashboard in the valve body by valve gap, have support at handwheel, on valve gap, also be provided with gland; It is characterized in that: be provided with wear sleeve at valve body, constitute wear-resistant passage by wear sleeve, wear sleeve is provided with wear-resistant groove, wear-resistant dome arc and wear-resistant sealing surface, and the sealing surface of its wear-resistant sealing surface and flashboard constitutes sealing and pays structure.
The material that above-mentioned wear sleeve adopts is abrasive-resistant material KMTBCr26.
The utility model adopts high abrasive-resistant material, and is simple in structure, good seal performance, and flashboard opens and closes flexibly, and operation and maintenance is convenient, has improved the wear resistance of valve, and improve working life; Its antiwear property and shock resistance improve more than 8 times than general cast steel throttle valve, improve more than 4 times than the life of valve of other wear resistance linings, and its wear-resisting property is 20 times of No. 45 steel.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model form structure schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, 2, the utility model power plant special antiwear throttle valve is made up of valve body 1, valve rod 2, valve gap 3, support 4 and handwheel 5, and wherein, valve rod 2 is connected with valve body 1 interior flashboard 6 with handwheel 5 and by valve gap 3, have support 4 at handwheel 5, on valve gap 3, also be provided with gland 7; Simultaneously be provided with wear sleeve 8 at valve body 1, constitute wear-resistant passage by wear sleeve 8, wear sleeve 8 is provided with wear-resistant groove 9, wear-resistant dome arc 10 and wear-resistant sealing surface 11, and the sealing surface 12 of its wear-resistant sealing surface 11 and flashboard constitutes sealing and pays structure.
The material that above-mentioned wear sleeve 8 adopts is abrasive-resistant material KMTBCr26.
When the utility model uses, do elevating movement by rotating handwheel drive valve rod, thereby drive flashboard unlatching or throttle down, in pipeline, work to regulate rate-of flow, because the runner that medium is flowed through is wear-resistant passage, so improved the working life of throttle valve.
