閥門連接面的安裝注意事項

來源:http://m.serviceforo.com/ 日期:2021-10-02 發(fā)布人:admin
關(guān)于閥門鏈接面的安裝事項,良工山東銷售提醒大家裝置端部選用螺紋銜接的閥門,應(yīng)使螺紋擰入閥門的深淺適合,螺紋擰入過深壓緊閥座,將影響閥座和閘板的杰出配合,擰入過淺,將影響接頭的密封可靠性,簡單引入走漏。一起螺紋密封材料應(yīng)選用要四氟乙烯生膠帶貨密封膠,留意不要把密封材料給到閥門內(nèi)腔。
As for the installation of the valve connecting surface, Lianggong valve Chongqing Sales Center reminds everyone that the valve with threaded connection shall be selected at the end of the device, and the depth of the thread screwed into the valve shall be suitable. If the thread is screwed too deep and compresses the valve seat, it will affect the excellent cooperation between the valve seat and the gate, and if it is screwed too shallow, it will affect the sealing reliability of the joint and simply introduce leakage. Teflon raw tape sealant shall be selected as the thread sealing material, and attention shall be paid not to give the sealing material to the inner cavity of the valve.
關(guān)于法蘭端部銜接的閥門,首先要找正法蘭的銜接面,封面垂直于管線,且螺栓孔要對正。閥門法蘭應(yīng)與管道法蘭平行,法蘭空隙適中,不該呈現(xiàn)錯口、歪斜等表象,法蘭間心墊片應(yīng)放置正中,不能偏斜,螺栓應(yīng)對稱均勻擰緊。避免在閥門裝置時強(qiáng)行銜接擰緊,發(fā)生一個附加殘余力。

For the valve connected at the flange end, first align the connecting surface of the flange, the cover is perpendicular to the pipeline, and the bolt hole shall be aligned. The valve flange shall be parallel to the pipe flange, the flange gap shall be moderate, and the appearance of staggered mouth and skew shall not be presented. The center gasket between flanges shall be placed in the center without skew, and the bolts shall be tightened symmetrically and evenly. Avoid forcibly connecting and tightening the valve device, resulting in an additional residual force.
裝置前要徹底鏟除管子內(nèi)壁及外部螺紋的污物;鏟除有礙介質(zhì)活動和能夠影響設(shè)備工作的毛刺、異物等,在管子銜接前吹凈管道中的污垢、渣及其他雜物。避免損害閥門的密封面或堵塞閥門。
Before installation, the dirt on the inner wall and external thread of the pipe shall be completely removed; Remove burrs and foreign matters that hinder media activities and can affect equipment operation, and blow out dirt, slag and other sundries in the pipeline before pipe connection. Avoid damaging the sealing surface of the valve or blocking the valve.
裝置焊接端部銜接閥門,應(yīng)先組對點焊后閥門兩頭焊口,敞開閥門,然后按焊接工藝卡施焊焊縫,焊后對焊縫外觀及內(nèi)在焊縫質(zhì)量進(jìn)行查看,保證無氣孔、夾渣、裂紋等,需求時應(yīng)對焊縫進(jìn)行射線或超控查看。
When connecting the valve at the welding end of the device, first assemble the welded junctions at both ends of the valve after spot welding, open the valve, and then weld the weld according to the welding process card. After welding, check the appearance and internal weld quality of the weld to ensure that there are no pores, slag inclusions, cracks, etc. the weld shall be shot or overridden when required.
較重閥門的裝置
Device for heavier valves
裝置較重的閥門時(DN>100),應(yīng)用起吊東西或設(shè)備,起吊繩索應(yīng)系在閥門的法蘭或支架上,不該系在閥門的手柄式閥桿上,避免損壞閥門。
For valves with heavy devices (DN > 100), lifting objects or equipment shall be used. The lifting rope shall be tied to the flange or support of the valve, not to the handle valve stem of the valve, so as to avoid damaging the valve.
