進口氮氣減壓閥產品信息

進口氮氣減壓閥
一、進口氮氣減壓閥產品概述
品牌：美國歐可OKE
進口氮氣減壓閥（Nitrogen pressure reducing valve），也叫氮氣調壓閥，是指用于氮氣介質，通過調節彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化，通過導閥啟閉驅動活塞調節主閥節流部位過流面積的大小，實現對壓縮空氣的減壓穩壓功能。從流體力學的觀點看，減壓閥是一個局部阻力可以變化的節流元件，即通過改變節流面積，使流速及流體的動能改變，造成不同的壓力損失，從而達到減壓的目的。然后依靠控制與調節系統的調節，使閥后壓力的波動與彈簧力相平衡，使閥后壓力在一定的誤差范圍內保持恒定。

二、進口氮氣減壓閥產品特征
1、用于壓縮空氣的管道介質。
2、屬于先導活塞式減壓閥。由主閥和導閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導閥主要由閥座、閥瓣、膜片、彈簧、調節彈簧等零件組成。控制精確。
3、通過調節調節彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化，通過導閥啟閉驅動活塞調節主閥節流部位過流面積的大小，實現減壓穩壓功能。進口壓力不斷變化的情況下，保持出口聽壓力和溫度值在一定的范圍內

六、進口氮氣減壓閥安裝說明
1、氣體減壓閥安裝必須嚴格按照閥體上的箭頭方向保持和流體流動方向一致。如果氣體不清潔含有一些雜質，必須在減壓閥的上游進水口安裝過濾器(我們建議過濾精度不低于0.5mm)。
2、為了操作和維護方便，氣體減壓閥一般直立安裝在水平管道上。
3、為了防止氣體減壓閥閥后壓力超壓，應在離閥出口不少于4M處加裝一個減壓閥。
4、減壓閥閥前和閥后必須裝截止閥，更換或者維修時開關氣體用
5、氣體如果有冷凝水的話，需要裝汽水分離器，防止冷凝水對減壓閥活塞或者膜片的損壞。

Imported nitrogen pressure reducing valve
I. Overview of imported nitrogen pressure reducing valve products
Brand: US Ouke OKE
Nitrogen pressure reducing valve, also called nitrogen pressure regulating valve, is used for nitrogen medium. The outlet pressure is set by adjusting the spring pressure, and the outlet pressure of the diaphragm is sensed by the diaphragm. The piston adjusts the size of the flow area of ??the throttle portion of the main valve to realize the decompression and pressure regulation function of the compressed air. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of decompression. Then, relying on the adjustment of the control and regulation system, the fluctuation of the post-valve pressure is balanced with the spring force, so that the post-valve pressure remains constant within a certain error range.

Second, the characteristics of imported nitrogen pressure reducing valve
1. Pipe medium for compressed air.
2. It belongs to the pilot piston type pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve is mainly composed of a valve seat, a main valve disc, a piston, a spring and the like. The pilot valve is mainly composed of a valve seat, a valve disc, a diaphragm, a spring, an adjustment spring and the like. Control is precise.
3. Adjust the outlet pressure by adjusting the spring pressure, and use the diaphragm to sense the outlet pressure change. The pilot valve is opened and closed by the pilot valve to adjust the overflow area of ??the throttle portion of the main valve to realize the pressure reduction and voltage stabilization function. Keeping the outlet listening pressure and temperature within a certain range when the import pressure is constantly changing

Sixth, the installation of imported nitrogen pressure reducing valve
1. The gas pressure reducing valve must be installed in strict accordance with the direction of the arrow on the valve body and the direction of fluid flow. If the gas is not clean and contains some impurities, the filter must be installed at the upstream inlet of the pressure reducing valve (we recommend a filtration accuracy of not less than 0.5mm).
2. For ease of operation and maintenance, the gas pressure reducing valve is generally installed upright on a horizontal pipe.
3. In order to prevent pressure overpressure after the gas pressure reducing valve, a pressure reducing valve should be installed at not less than 4M from the valve outlet.
4. The pressure reducing valve must be equipped with a shut-off valve before and after the valve, and the switch gas should be used for replacement or maintenance.
5. If the gas has condensed water, it needs to be equipped with a steam separator to prevent the condensate from damaging the piston or diaphragm of the pressure reducing valve.
