隔膜式加藥泵吸排液閥改進(jìn)探討


為避免吸排液閥過(guò)早失效,設(shè)計(jì)在閥球的結(jié)構(gòu)和材料上進(jìn)行改進(jìn),加藥泵使閥的有效過(guò)流面積盡可能的大,保證其具有合適的導(dǎo)向間隙,能獲得良好的導(dǎo)向?qū)χ行裕凶銐虻膲勖,并易于維修。密封閥座由唇形接觸改為矩形密封套,材質(zhì)采用聚氨脂,邵氏硬度為60-65。在閥球?qū)蚪Y(jié)構(gòu)上采用對(duì)稱的4條三角形鑲嵌式導(dǎo)向筋,使閥球側(cè)隙始終保持穩(wěn)定,閥球沿軸線平穩(wěn)地上下運(yùn)動(dòng),同時(shí)減少其與閥球的接觸面積,減少磨損。在結(jié)構(gòu)方面,為保證閥球在使用中具有穩(wěn)定的跳高尺寸,除提高密封閥座的耐磨性、減少磨損外,在閥球跳起的上端增加緩沖橡膠墊,以消除閥球向上跳起時(shí)的沖擊力對(duì)限高支架的磨損。在吸排液閥的整體結(jié)構(gòu)方面,采用了組合式結(jié)構(gòu),由閥底座、單向閥、壓板及壓緊螺栓組成,使其在使用中可方便拆卸、安裝、檢查及更換閥體各部件,避免了直連式結(jié)構(gòu)中拆卸造成泵頭連接螺紋的損傷。改進(jìn)后的加藥泵吸排液閥具有設(shè)計(jì)合理的泵閥結(jié)構(gòu)和制作材料,保證了在使用周期內(nèi)不更換易損件(圖\文brfr.com.cn/)。
中譯英:
In order to avoid the premature failure of suction and discharge valve, ball valve design in structure and materials were improved, dosing pump valve effective flow area as large as possible, ensuring an appropriate orientation space, can obtain the good guidance to the neutral, have long service life, and easy to repair. Sealing valve seat by a lip contact is changed into a rectangular sealing sleeve, is made of polyurethane, Shaw hardness 60-65. The valve ball guide structure with symmetric 4 triangles inlaid rib guide, so that the ball valve backlash has remained stable, the valve ball along the axis of smooth moves up and down, while reducing with the valve ball contact area, reducing wear. In terms of structure, in order to ensure the ball valve in use with a stable high jump size, in addition to improve the sealing valve seat wear resistance, reduce wear, the valve ball to upper increased buffering rubber pad, to remove the valve ball up when the impact force on the high limit bracket wear. In the suction and discharge valve structure, adopts a combined structure, composed of a valve base, a one-way valve, pressure plate and the clamping bolt component, which can be conveniently disassembled, installation, inspection and replacement body parts, to avoid the type of detaching the resulting pump head connecting screw thread damage. The improved dosing pump suction valve has the advantages of reasonable design of the valve structure and production of materials, ensure that the use of periods with no replacement of wearing parts.
