Description  Langue du texte original : Chinois
氯碱用氟塑料全衬蝶阀 Chlor fully padded with fluorine plastic butterfly

本实用新型是一种用于化工氯碱管道上控制介质流动的一种氯碱用氟塑料全衬蝶阀。 The utility model is a medium for controlling the flow of a chlor alkali chemical pipelines on the whole lining fluorine plastic butterfly.

经检索有关专利文献,尚未发现与本实用新型结构相同的蝶阀。 After retrieving the relevant patent documents, not yet discovered the structure of the utility model and the same butterfly. 目前国内化工行业使用的蝶阀内,由于不具有抗强腐蚀的氟塑料全衬,阀体极易被腐蚀,发生泄漏,产生事故,造成经济损失。 At present, the domestic chemical industry to use in the butterfly, and because they do not have strong anti-corrosive fluorine plastic full lining, the body vulnerable to corrosion, leaks, resulting in an accident, resulting in economic losses.

本实用新型的目的是提供一种能抗强腐蚀,密封性能好,耐低温,使用安全可靠的氯碱用氟塑料全衬蝶阀。 The utility model aims to provide a strong anti-corrosion, good sealing performance, low temperature, the use of safe and reliable chlor fully padded with fluorine plastic butterfly.

本实用新型的技术解决方案是:氯碱用氟塑料全衬蝶阀,包括上阀体、下阀体、蝶板、上、下导套、传动部件,其特征是:在阀体内腔装有用聚全氟乙丙烯制成带两端密封面的圆形衬套,在阀体与衬套间装有多层填料,蝶板设为圆弧形,在其表面热覆有聚全氟乙丙烯。 The utility model technical solutions are: chlor-alkali fully padded with fluorine plastic butterfly, including the body, lower body, disc, the upper and lower bushings, transmission parts, which is characterized by: the body cavity is equipped with a poly- FEP liner is made with a circular sealing surface at both ends, in between the body and the bushing fitted with a multi-layer packing, the disc is set to the arc-shaped, its surface covered with polyethylene thermal FEP. 在上、下阀体中部设有密封槽,槽内装有填料。 The upper and lower central body provided with a sealing groove, the groove containing the filler. 在上、下导套的内壁上镶嵌有钢套。 On, inlaid with steel sleeve on the inner wall of the lower guide sleeve. 在蝶板的上、下轴与上、下阀体联接处装有蝶形弹簧,在蝶形弹簧的端点装有上、下导套。 On the disc, the lower shaft and upper and lower joint of the body is equipped with disc springs, disc springs on endpoints equipped, under the guide sleeve.

安装在管道上的氯碱用氟塑料全衬蝶阀,当转动传动部件,带动蝶板开启,使流体介质通过。 Chlor installed in the pipe with a fluorine plastic full lining butterfly, when the rotation transmission components, open the disc drive, through a fluid medium. 反之,当蝶板关闭,阻止流体介质通过。 Conversely, when the disc is closed, preventing fluid medium through.

本实用新型的优点是:结构新颖合理,由于阀体与衬套之间设有多层填料,当蝶板关闭时,蝶板挤压衬套,阀体与衬套之间产生弹性变形,使蝶板与衬套间构成无间隙密封。 The utility model has the advantage: new structure is reasonable, because the filler between the body and has a multi-layer liner, when the disc is closed, the disc extrusion elastic deformation between the bush, the body and the bush, so disc with no gap between the bushing constitute seal. 由于在阀体内腔装有采用聚全氟乙丙烯的衬套,使阀体内的强腐蚀性介质与上、下阀体不接触,避免阀体被腐蚀,同时衬套可长期使用温度在-40℃-250℃之间,并具有绝缘性、抗老化性,表面不粘性,良好的润滑性。 Since the body cavity equipped with FEP using poly bushings, valve body strong corrosive medium upper and lower body are not in contact, to avoid corrosion of the body, while the bush long-term use temperature of -40 between ℃ -250 ℃, and have insulation resistance, aging resistance, the surface is not sticky, good lubricity. 由于蝶板设为圆弧形,当关闭蝶阀时,蝶板逐步挤压衬套,构成无间隙密封。 Due to the arc-shaped disc, when closing valve, the disc gradually squeeze bushings, constitute no gap seals. 确保蝶阀密封可靠。 Ensure reliable sealing butterfly. 由于在上、下导套的内壁上镶嵌有铜套,使上、下导套增强耐磨,从而提高蝶阀的使用寿命。 Because the upper and lower inner wall of the guide sleeve inlaid with copper sleeve, the upper and lower bushings enhance wear resistance, thereby increasing the life of the butterfly. 由于在蝶板的上、下轴与上、下阀体联接处装有蝶形弹簧,蝶形弹簧产生的压力,压住填料,可避免蝶板上、下两轴处泄漏,使用安全可靠,能满足氯碱管道上连续运行的使用要求。 Because of the disc, the lower shaft and upper and lower body at the air-pressure coupling spring butterfly, butterfly spring produced suppress fillers can avoid butterfly board, under the two axes of the leak, the use of safe, reliable, able to meet the requirements of the chlor-alkali pipeline continuous operation.
