Ako vykonávať bežnú údržbu a výmenu tesnenia pre plastové ventily ?
1. Regular inspection of valve body and sealing surfaces: Visually inspect the valve body, seat, and gaskets monthly, recording any scratches, wear, or signs of aging.
2. Čistenie a mazanie: Na odstránenie oleja a prachu z povrchu tela ventilu použite handričku, ktorá nepúšťa vlákna, alebo špeciálny čistiaci prostriedok; naneste vhodné množstvo chemicky odolného maziva na pohyblivé časti (ako sú pružiny a drieky ventilov), aby ste zabránili zaseknutiu.
3. Rýchle kroky na výmenu tesnenia: ① Odstráňte telo ventilu a zaistite montážny blok; ② Rýchlo uvoľnite staré tesnenie pomocou zacvakávacej konštrukcie medzi pružinou a montážnou doskou; ③ Po skontrolovaní poškodenia pružiny a montážnej tyče nainštalujte nové tesnenie a znova ho zaklapnite. This patented snap-fit limiting design significantly improves replacement efficiency and is applicable to the entire range of plastic valves from Jiangsu Leiting Precision New Materials Co., Ltd.
4. Functional verification: After replacement, perform a closed/open cycle test to confirm no leakage and smooth operation before putting the valve into use.
Aké sú kľúčové úvahy pri balení a preprave produktov PlasticValveSeries?
1. Packaging Material Selection: Use moisture-proof and shock-proof polyethylene or corrugated cardboard boxes, clearly marked with "Moisture-proof, Pressure-proof" to ensure the valve body is protected from moisture or impact damage during long-distance transport.
2. Protective Measures: Each valve body is internally filled with PE foam or EPE granules, and partitions are installed between valve bodies to prevent mutual friction; k ľahko poškriabaným krytom ventilov a prírubám sú pridané mäkké ochranné návleky.
3. Labeling and Instructions: The packaging must clearly indicate the product model, specifications, weight, quantity per carton, and the words "Lightweight Plastic Valve"; mala by byť priložená aj používateľská príručka pre rýchlu identifikáciu zákazníkom na mieste.
4. Spôsob prepravy a nakladanie: Pre celokontajnerovú prepravu sa uprednostňujú nákladné autá alebo kontajnery. Počas nakladania udržujte nádobu vodorovne, aby ste sa vyhli nakloneniu alebo silným nárazom; pre veľké zásielky je možné použiť paletové stohovanie s dostatočnými medzerami medzi paletami, aby sa zabránilo deformácii pod tlakom.
Výhody radu PlasticValveSeries v praktických aplikáciách:
1. Lightweight and High-Strength: Compared to metal valves, plastic valves weigh only 30%~40% of metal valves, reducing pipeline support structure costs.
2. Corrosion-Resistant and Scaling-Free: Utilizing high-molecular materials (such as PTFE and modified polyurethane), they maintain long-term sealing performance in strong acid, alkali, and salt spray environments, making them suitable for demanding industries such as solar energy, semiconductors, and chemicals.
3. Integrated Connection: The valve body can be directly heat-fused or snap-fitted to plastic pipes, eliminating the need for additional flange gaskets, shortening installation time and reducing leakage risk.
4. Technological Innovation and Patent Protection: As of December 2024, the company held 81 patents (36 invention patents, 36 utility model patents, and 9 design patents), including a snap-fit structure for easy seal replacement, further enhancing maintenance convenience.
