選擇調(diào)壓閥時(shí)需要考慮什么？
此處列出了選擇調(diào)節(jié)閥的主要考慮因素。 根據(jù)您特定應(yīng)用的要求，使用此目錄查找與您的參數(shù)匹配的調(diào)節(jié)器。 標(biāo)準(zhǔn)產(chǎn)品只是一個(gè)起點(diǎn)。 可以通過修改或創(chuàng)建一個(gè)控件來解決您最棘手的應(yīng)用問題。 詳細(xì)信息可通過您當(dāng)?shù)氐?TESCOM 代表獲得。
Major considerations in the selection of a regulator are listed here. Within the requirements of your specific application, use this catalog to find the regulator that matches your parameters. Our standard products are only a starting point. We can modify or create a control that will solve your toughest application problem. Detailed information is available through your local TESCOM representative.
手動(dòng)旋鈕①
大號(hào)手動(dòng)旋鈕提供簡(jiǎn)單、低扭矩的壓力設(shè)置。 某些型號(hào)的扳手或螺絲刀調(diào)整選項(xiàng)。
HANDKNOB
Large handknob provides easy, low torque pressure setting. Wrench or screwdriver adjust options on some models.
排氣②
當(dāng)把手向“減小”方向轉(zhuǎn)動(dòng)時(shí)，排氣功能可以釋放出口壓力。
捕獲的排氣配置包括額外的端口，用于將排出的流體從調(diào)節(jié)器的排氣閥中排出。
非排氣功能可用于不需要排氣的液壓或其他應(yīng)用。
VENTING
Venting feature enables relieving of the outlet pressure when the handknob is turned in the “decrease” direction.
Captured venting configuration includes extra port to pipe away expelled fluids from a regulator’s vent valve.
Non-venting feature available for hydraulic or other applications where venting is not desirable.
流量 – Cv
CV 是調(diào)節(jié)器流量的量度。 流量系數(shù)是指 1 GPM 水在 1 psi 下降時(shí)通過主閥的流量。 氣體服務(wù)的系數(shù)必須由入口與出口壓力之比確定。
FLOW CAPACITY – Cv
Cv is a measure of regulator flow capacity. The flow coefficient refers to the flow of one GPM of water at one psi drop across the main valve. The coefficient for gaseous service must be determined from the ratio of inlet to outlet pressure.
主體材料③
黃銅、鋁或不銹鋼（300、316 型）等。
BODY MATERIALS
Brass, aluminum or stainless steel (Type 300, 316) and others.
可用的出口壓力范圍
從 50 mm Hg 絕對(duì)壓力到 15 psig / 1 bar，范圍高達(dá) 300-20,000 psig / 21-1379 bar。
OUTLET PRESSURE RANGES AVAILABLE
Starting at 50 mm Hg absolute to 15 psig / 1 bar, ranging up to 300-20,000 psig / 21-1379 bar.
加載 - 彈簧、圓頂、氣動(dòng)、電子④
加載是指用于平衡出口壓力的方法。 彈簧加載與帶手動(dòng)調(diào)節(jié)的直接作用調(diào)節(jié)器一起使用。
圓頂加載最常用于高流量、快速響應(yīng)型應(yīng)用。
空氣執(zhí)行器提供高達(dá) 15,000 psig /1035 bar 的出口壓力，信號(hào)僅為 100 psig / 6.9 bar。
TESCOM 電子控制器是另一種加載選項(xiàng)。
LOADING – Spring, Dome, Air Actuated, Electronic
Loading refers to the methods used to balance the outlet pressure. Spring loading is used with direct acting regulators with handknob adjustment.
Dome loading is most often used in high flow, quick response type applications.
Air Actuator provides outlet pressures up to 15,000 psig /1035 bar with a signal of only 100 psig / 6.9 bar.
A TESCOM electronic controller is another loading option.
面板安裝
某些型號(hào)標(biāo)準(zhǔn)設(shè)置。 其他的額外選擇。
PANEL MOUNTING
Standard on some models. Extra option on others.
傳感 – 隔膜或活塞⑤
隔膜為高達(dá) 500 psig / 35 bar 的出口壓力范圍提供靈敏和準(zhǔn)確的調(diào)節(jié)。
活塞傳感器為高達(dá) 20,000 psig / 1379 bar 的高出口壓力提供高強(qiáng)度完整性。
SENSING – Diaphragm or Piston
Diaphragms provide sensitive and accurate regulation for outlet pressure ranges up to 500 psig / 35 bar.
Piston sensors provide high strength integrity for high outlet pressures up to 20,000 psig / 1379 bar.
入口壓力范圍
低于大氣壓至 20,000 psig / 1379 bar。
INLET PRESSURE RANGES
Sub-atmospheric to 20,000 psig / 1379 bar.

主閥 – 平衡和不平衡⑦
平衡設(shè)計(jì)用于減少入口壓力衰減的影響，并且在某些型號(hào)中提供增加的流量。
不平衡閥簡(jiǎn)單和經(jīng)濟(jì)。
MAIN VALVES – Balanced and Unbalanced
Balanced design is used to reduce the effect of decaying inlet pressure and in certain models provides increased flow capacity.
Unbalanced valve offers simplicity and economy.
