產(chǎn)品結(jié)構(gòu)特點(diǎn) afeatures
1)密封比壓高：水煤漿工況用硬密封球閥由于采用金屬材料為密封面，所需要的密封比壓比軟。
密封要高得多：因此如何從設(shè)計(jì)上保證適當(dāng)?shù)拿芊獗葔?，提高零件的形位公差以及提高表面光潔度要求是十分重要的?br> 2)球體表面硬度高：煤粉顆粒的硬度較高，此工況情形下，在閥門關(guān)閉的狀態(tài)時(shí)要求球體表面。
硬度層有較高的硬度,否則,當(dāng)閥門開啟的過程中會(huì)有煤粉顆粒鑲嵌在球體表面上，
從而破壞球體表面,以至于影響到閥門的整體密封性能。
3)噴焊層結(jié)合強(qiáng)度高：煤粉在管線中的流動(dòng)速度很快，因此要求球體密封面必須有較高的硬度。
和強(qiáng)度,同時(shí)還要求所噴焊的密封材料和基體材料有較高的結(jié)合強(qiáng)度，以及基體材料本身的強(qiáng)度較好，這樣噴焊層才不能從基體表面脫落，而失去密封性能。
4)自潔功能：煤漿的吸附性較強(qiáng)，容易粘在球體表面上。在閥門啟閉過程中，介質(zhì)顆粒被帶到。
閥座與球體的密封面之間，破壞了球體與閥座之間的密封副，從而影響閥門的密封性能，使閥門的使用壽命大大縮短。這就要求閥門具有很好的“自潔"功能，從而保證球體和閥座密封副不被破壞。
5)加工難：由于水煤漿工況用硬密封球閥的密封表面均采用超硬材料或表面硬化處理，用普通刀具無法加工,即使能加工其加工精度也不能滿足要求，同時(shí)還要求加工設(shè)備具有足夠的強(qiáng)度，因此選擇合適的刀具非常重要。
1) The sealing ratio is higher than the pressure: the sealing ball valve in the working conditions of the coal slurry USES the metal material as the sealing cover and the required sealing ratio is softer than the pressure ratio.
The sealing is much higher: therefore, it is very important to ensure proper sealing ratio of the design, improve the position tolerance of the parts and improve the surface finish.
2) The surface hardness of the ball is high: the hardness of coal particles is higher, and the surface of the sphere is required when the valve is closed in this condition.
Hardness layer has high hardness, otherwise, when the valve is opened in the process of coal particles are embedded in a sphere surface, undermining the sphere surface, that affect the overall sealing performance of the valve.
3) The bonding strength of the spray welding layer is high: the coal powder is flowing fast in the pipeline, so it is necessary to have a high hardness on the sealing surface of the ball.
And intensity, and at the same time also requires the spray welding sealing material and base material has high bonding strength, and the strength of the
substrate material itself is good, so just can't fall off from the substrate surface spray welding layer, and lose the sealing performance.
4) Self-cleaning function: the adsorption properties of coal pulp are strong and easy to stick to the surface of the ball. During the valve opening process, the medium particles are carried.
Between the seat and the ball's sealing surface, the seal between the ball and the seat is broken, which affects the sealing performance of the valve and greatly reduces the service life of the valve. This requires the valve to have a good "self-cleaning" function to ensure that the ball and seat seal are not damaged.
5) Processing hard: as the working condition of coal water slurry with hard seal ball valve sealing surface adopt superhard material or surface hardening treatment, use common tool will not be able to process, even to the machining precision can't meet the requirements, at the same time also require processing equipment has enough strength, therefore is very important to choose the appropriate tools.
