PPR截止閥與閘閥產(chǎn)品說(shuō)明
PPR截止閥和閘閥是流體控制系統(tǒng)中不可或缺的關(guān)鍵組件，采用優(yōu)質(zhì)無(wú)規(guī)共聚聚丙烯（PPR）材料制成，適用于冷熱水輸送、暖通系統(tǒng)及工業(yè)管道領(lǐng)域。產(chǎn)品涵蓋20mm、25mm、32mm、40mm、50mm、63mm等常用規(guī)格，可滿足不同場(chǎng)景的安裝需求。
材質(zhì)特性
PPR材質(zhì)具備優(yōu)異的耐高溫性（長(zhǎng)期耐受70℃水溫，短期耐受95℃水溫）、抗化學(xué)腐蝕性及環(huán)保安全性，長(zhǎng)期使用不結(jié)垢、不滋生細(xì)菌，符合生活用水衛(wèi)生要求。閥門(mén)內(nèi)壁光滑，可有效降低流體阻力，減少能源損耗。
結(jié)構(gòu)設(shè)計(jì)
截止閥采用精密模壓工藝成型，閥桿與閥座接觸面經(jīng)過(guò)特殊處理，確保啟閉靈活且密封性能穩(wěn)定；閘閥主體結(jié)構(gòu)采用流線型設(shè)計(jì)，全通徑結(jié)構(gòu)使流體通過(guò)時(shí)無(wú)阻礙，適用于需要完全開(kāi)啟或關(guān)閉的管道場(chǎng)景。兩種閥門(mén)均配備耐磨損EPDM密封圈，有效防止?jié)B漏，延長(zhǎng)使用壽命。
應(yīng)用優(yōu)勢(shì)
- 安裝便捷：熱熔承插連接方式簡(jiǎn)單高效，與PPR管道系統(tǒng)兼容性強(qiáng)
- 維護(hù)成本低：耐候性?xún)?yōu)異，不受水質(zhì)影響，長(zhǎng)期使用無(wú)需頻繁更換
- 適配性強(qiáng)：多規(guī)格尺寸可匹配不同流量需求，適用于家庭供水、農(nóng)業(yè)灌溉及商業(yè)建筑等多種場(chǎng)景
規(guī)格參數(shù)
- 公稱(chēng)直徑：20/25/32/40/50/63mm
- 工作壓力：PN20（常規(guī)冷水）/PN16（高溫?zé)崴?/li>
- 適用介質(zhì)：冷熱水、中性液體
PPR Stop Valves & Gate Valves Product Description
PPR stop valves and gate valves are essential components in fluid control systems, manufactured from premium polypropylene random copolymer (PPR) material. These valves are widely used in cold/hot water supply, HVAC systems, and industrial pipelines, available in 20mm, 25mm, 32mm, 40mm, 50mm, and 63mm specifications to meet diverse installation requirements.
Material Properties
PPR material exhibits outstanding heat resistance (withstands 70℃ long-term and 95℃ short-term), chemical corrosion resistance, and environmental safety. The smooth inner surface prevents scaling and bacterial growth, ensuring compliance with potable water hygiene standards while minimizing flow resistance.
Structural Design
Stop valves feature precision-molded bodies with specially treated spindle-seat contact surfaces for smooth operation and reliable sealing. Gate valves adopt full-bore streamlined design for unrestricted flow in fully open/closed positions. Both types integrate wear-resistant EPDM sealing rings to prevent leakage and extend service life.
Functional Advantages
- Easy Installation: Compatible thermal fusion connection ensures seamless integration with PPR piping
- Low Maintenance: Excellent weather resistance and material stability reduce long-term upkeep
- Versatile Application: Multiple sizes accommodate varying flow demands in residential, agricultural, and commercial systems
Technical Parameters
- Nominal Diameter: 20/25/32/40/50/63mm
- Pressure Rating: PN20 (cold water)/PN16 (hot water)
- Compatible Media: Cold/hot water, neutral liquids
