簡易選型流程

Simplified selection process

明確介質(zhì)類型→2. 確定溫度 / 壓力 / 管徑→3. 按功能選閥門類型→4. 匹配材質(zhì)與驅(qū)動方式→5. 核對標(biāo)準(zhǔn)與認(rèn)證→6. 選擇靠譜品牌及采購渠道。

Clarify the type of medium → 2. Determine temperature/pressure/pipe diameter → 3 Select valve type by function → 4. Match material and drive mode → 5 Verify standards and certifications → 6. Choose reliable brands and procurement channels.

選閥門不同的方面來選擇

Choose valves from different aspects

閥門的功能:根據(jù)閥門是用于切斷還是調(diào)節(jié)流體的流量和壓力來選擇,如需快速啟閉則應(yīng)考慮閘閥、截止閥、球閥、蝶閥等通用閥門,調(diào)節(jié)流量的可選擇電動或氣動調(diào)節(jié)閥,調(diào)節(jié)壓力的選擇減壓閥。

The function of the valve: It is selected based on whether the valve is used to cut off or regulate the flow and pressure of the fluid. If quick opening and closing is required, universal valves such as gate valves, globe valves, ball valves, butterfly valves, etc. should be considered. Electric or pneumatic regulating valves can be selected for regulating flow, and pressure reducing valves can be selected for regulating pressure.

閥門的尺寸:根據(jù)流體的流量和允許的壓力損失來決定閥門的尺寸,一般應(yīng)與工藝管道的尺寸一致。

Valve size: The size of the valve is determined based on the fluid flow rate and allowable pressure loss, and should generally be consistent with the size of the process pipeline.

流體的溫度和壓力:根據(jù)閥門的工作溫度和壓力來確定閥門的材質(zhì)和壓力等級。介質(zhì)的腐蝕性。根據(jù)介質(zhì)的腐蝕性確定閥門材料。

Temperature and pressure of fluid: Determine the material and pressure rating of the valve based on its operating temperature and pressure. The corrosiveness of the medium. Determine valve materials based on the corrosiveness of the medium.

介質(zhì)的流速流量:根據(jù)介質(zhì)的流速流量確定閥門公稱直徑。安裝操作。根據(jù)安裝操作、管理經(jīng)濟(jì)性確定閥門結(jié)構(gòu)形式。

Flow rate of medium: Determine the nominal diameter of the valve based on the flow rate of the medium. Installation operation. Determine the valve structure form based on installation operation and management economy.

閥門材料:選擇閥門的主要零件的材質(zhì),首先應(yīng)考慮到工作介質(zhì)的物理性能(溫度、壓力)和化學(xué)性能(腐蝕性)等。

Valve material: When selecting the material of the main components of the valve, the physical properties (temperature, pressure) and chemical properties (corrosiveness) of the working medium should be considered first.

閥門驗(yàn)收:檢查外觀質(zhì)量和幾何尺寸,查看閥門產(chǎn)品合格證和質(zhì)量證明書,檢查閥門開啟關(guān)閉是否靈活。

Valve acceptance: Check the appearance quality and geometric dimensions, inspect the valve product certificate and quality certificate, and check whether the valve opens and closes flexibly.
