爲避免(miǎn)吸(xī)排液閥(fá)過(guò)早(zǎo)失效,設計(jì)在閥球的結(jié)構(gòu)和材料(liào)上(shàng)進行(háng)改進(jìn),
加藥(yào)泵
使閥的有效過流(liú)面積盡可(kě)能的(de)大,保證其具有合适(shì)的導(dǎo)向間(jiān)隙,能獲得良好的導向對中性(xìng),有足(zú)夠的壽命(mìng),并易(yì)于維(wéi)修。密(mì)封閥座(zuò)由(yóu)唇形(xíng)接觸改爲(wèi)矩形(xíng)密封(fēng)套,材質采(cǎi)用(yòng)聚氨脂(zhī),邵氏(shì)硬度(dù)爲60-65。在閥球(qiú)導向結(jié)構上采(cǎi)用對(duì)稱的(de)4條三(sān)角形鑲嵌式導(dǎo)向筋,使閥球側(cè)隙始終保(bǎo)持穩(wěn)定,閥球沿軸線(xiàn)平穩地上下運(yùn)動,同時減少其與閥球的(de)接觸(chù)面積,減(jiǎn)少磨損(sǔn)。在結構方(fāng)面,爲(wèi)保證(zhèng)閥(fá)球(qiú)在使(shǐ)用中具有穩定的跳高尺寸,除(chú)提高密封閥座的耐(nài)磨性、減少(shǎo)磨損(sǔn)外(wài),在閥球跳起(qǐ)的上端增(zēng)加緩沖橡膠墊(niàn),以消(xiāo)除閥球向(xiàng)上跳(tiào)起時的沖擊力(lì)對限高支(zhī)架的(de)磨損。在吸(xī)排液閥的整體(tǐ)結構方面,采用(yòng)了組(zǔ)合式(shì)結構(gòu),由閥(fá)底座(zuò)、單向(xiàng)閥、壓(yā)闆及壓緊(jǐn)螺(luó)栓組(zǔ)成(chéng),使其在使(shǐ)用中可方(fāng)便拆卸、安裝、檢(jiǎn)查及更(gèng)換閥體(tǐ)各部(bù)件,避免了直連式結構中(zhōng)拆卸造成(chéng)泵頭連接螺紋的損(sǔn)傷。改(gǎi)進後的
加藥泵
吸(xī)排液閥(fá)具有設(shè)計合理(lǐ)的泵閥結(jié)構和(hé)制作材料(liào),保證了在使(shǐ)用周期内不(bú)更換易損(sǔn)件(圖\文

中(zhōng)譯英(yīng):
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.
