　　过滤式全焊接球阀（自滤式焊接球阀）在自滤式焊接球阀开启状态下，流体介质通过球体的通孔内腔时，可以由自身设置的过滤网对流体介质进行过滤，当球体顺时针旋转90度时，自滤式焊接球阀处于关闭状态，起截断输送管道中流体介质的 retz品牌 filtered weldingball valve (self filtering welding ball valve) when the self filtering weldingball valve is open, when the fluid medium passes through the through holecavity of the ball, the fluid medium can be filtered by the filter screen setby itself. when the ball rotates 90 degrees clockwise, the self filteringwelding ball valve is closed, cutting off the fluid medium in the transmissionpipeline

　　进口过滤式全焊接球阀技术特点technology features

　　①整体式焊接球阀，不会有外部泄漏现象。withthe integrated welding ball valve, there will be no external leakagephenomenon.

　　②阀座由碳化特氟龙密封环及弹簧构成，对压力和温度变化适应能力强，在标注压力和温度范围内不会产生任何泄漏。thevalve seat is constituted by carbonized teflon seal ring and spring with strongability to adapt pressure and temperature changes. within the standard pressureand temperature range, there will be no leakage.

　　③球体的加工过程由先进的计算机检测仪跟踪检测，球体的加工密度高。themanufacturing process of the ball is traced and tested by the advanced computerdetector. the ball has a high manufacturing density.

　　④密封环采用含量20%carbon碳素的c-ptfe材质，保障完全无泄漏。the seal ringadopts c-ptfe material with 20% carbon to guarantee no leakage at all.

　　⑤与同类相同规格产品相比，阀体小，重量轻，外形美观，使用寿命长。comparedwith similar products or products of the same specification, thevalve body issmall and light with a beautiful appearance and long service life.

　　⑥阀体、球体及边阀体均采用无缝钢管压制成型。阀杆处采用双道"o型圈"密封，并且具有防吹出功能。the valve body,ball and side valve body all adopt seamed steel pipes molded by pressing. atthe valve rod, use the double "o-ring" for seal with the blow-offresistant function.

　　⑦过滤网与球体合为一体，滤网球阀链接在管道中本身有过滤功能，可以替代过滤器进行使用，起到一阀多用的效果，节省了管道安装空间及运营成本，可以阻拦直径大于4.5mm的杂质通过。the filter networkand the ball combine as one. the link of the ball of filter network itselfplays a role of filtering in the pipeline and can replace the filter, achievingthe effect of one valve with multiple furtions. therefore, it's able to savethe installation space of pipeline and the business cost and stop impuritieswith a diameter of greater than 4.5mm.

　　⑧滤网采用坡型口设计，保障阀门在阻断杂质颗粒情况下介质正常通过，阀门正常工作。采用泄压阀设计，可调节阀体内外压差，提高阀门安全性能，同时可采用螺纹球阀替代泄压阀，操作更省时、省力、方便、灵活。thefilter network adopts the v-mouth to guarantee the normal pass of media in thecase of blocking impurity particles, while the valve can work normally. itadopts the pressure relief valve design which can adjust the internal andexternal pressure difference of the valve and improve its security , it's able to replace the pressure relief valve with a threaded ballvaalve to make the operation time-saving, labor-saving, convenient andflexible.
