之前介紹SY42AX煤礦水管路減壓閥應(yīng)用案例,現(xiàn)在介紹衛(wèi)生級減壓閥操作指南減壓閥是通過調(diào)節(jié),將進(jìn)口壓力減至某一需要的出口壓力,并依靠介質(zhì)本身的能量,使出口壓力自動保持穩(wěn)定的閥門。即通過改變節(jié)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(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié),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(nèi)保持恒定。是通過調(diào)節(jié),將進(jìn)口壓力減至某一需要的出口壓力,并依靠介質(zhì)本身的能量,使出口壓力自動保持穩(wěn)定的閥門。即通過改變節(jié)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(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié),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(nèi)保持恒定。

Sanitary pressure reducing valve
By adjusting the hand wheel to reduce the inlet pressure to a desired outlet pressure, and rely on the energy of the media itself, so that the outlet pressure automatically maintain a stable valve. That is, by changing the throttle area, the flow rate and fluid kinetic energy change, resulting in different pressure loss, so as to achieve the purpose of decompression. Then rely on the control and regulation of the system adjustment, the valve pressure fluctuations and spring balance, the valve pressure in a certain range of error remains constant.
Our company, the hygienic pressure reducing valve, to ensure the valve cavity and the surface of the health requirements, at the same time both ends of the chuck fast connection, easy to disassemble and clean the valve; In addition, this valve factory standard Diaphragm pressure gauge, the valve outlet side of the pipeline can be the actual pressure value of the decompression requirements for debugging and monitoring
Sanitary valves are mostly used in food, pharmaceutical, dairy, clean room, bio-engineering and other high-clean areas.

衛(wèi)生級減壓閥操作指南調(diào)壓步驟
1、關(guān)閉減壓閥前的閘閥,開啟減壓閥后的閘閥,制造下游低壓環(huán)境;
2、將調(diào)節(jié)螺釘
減壓閥
按逆時針旋轉(zhuǎn)至上位置(相對低出口壓力),然后關(guān)閉減壓閥后閘閥;
3、慢慢開啟減壓閥前的閘閥至全開;
4、順時針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘,將出口壓力調(diào)至所需要的壓力(以閥后表壓為準(zhǔn));調(diào)整好后,將鎖緊
螺母鎖緊,打開減壓閥后閘閥;
5、如在調(diào)整時出口壓力高于設(shè)定壓力,須從步開始重新調(diào)整,即只能從低壓向高壓調(diào)。
