HOERBIGER賀爾碧格反比例閥：PRNE 70-665438 080/100
反比例閥適應(yīng)各品牌空壓機(jī)：復(fù)盛.艾能.正力精工.浪潮.紅五環(huán).佳力士.......
反比例閥配合蝶式進(jìn)氣控制閥使用，當(dāng)系統(tǒng)壓力因用氣量減少而升高時(shí)，達(dá)到反比例閥設(shè)定壓力時(shí)，反比例閥動(dòng)作并減少控制空氣輸出量，空壓機(jī)進(jìn)氣閥伺服氣缸閥桿推力減少，在彈簧力的作用下，閥桿回縮，當(dāng)彈簧力與氣缸的氣體推力平衡時(shí)，閥桿處于半開狀態(tài)，滑片式壓縮機(jī)進(jìn)氣量減少至與系統(tǒng)用氣量相平衡。
反比例閥的調(diào)整比較簡(jiǎn)單，但要實(shí)現(xiàn)伺服汽缸的靈敏動(dòng)作則需要多次調(diào)整，反比例閥的調(diào)整目的是空氣壓力達(dá)到距壓力開關(guān)動(dòng)作的上下限均有0.02MPa時(shí)反比例閥動(dòng)作，以減少或增加滑片式壓縮機(jī)進(jìn)氣量使進(jìn)氣閥相應(yīng)關(guān)小或開大，提前調(diào)節(jié)空壓機(jī)容量，以減少空重負(fù)荷次數(shù)。反比例閥順時(shí)針方向調(diào)整有增加伺服氣缸進(jìn)氣量的效果，反之，則減少進(jìn)氣量。
反比例閥裝在進(jìn)氣閥伺服氣缸前面。當(dāng)系統(tǒng)壓力達(dá)到反比例閥的動(dòng)作壓力時(shí)。調(diào)節(jié)伺服汽缸動(dòng)作，伺服氣缸調(diào)節(jié)進(jìn)氣蝶閥開啟角度，從而調(diào)節(jié)了進(jìn)氣量、排氣量。
反比例閥連接螺紋:G1/4,排氣口通徑有0.8MM和1.0MM二種,反比例閥在壓縮機(jī)系統(tǒng)中控制進(jìn)氣閥的進(jìn)氣量，減低電機(jī)運(yùn)轉(zhuǎn)負(fù)荷達(dá)到節(jié)能效果。

Inverse proportion with inlet butterfly valve is used, sliding-vane compressor when the system pressure rises, due to gas reduced to inverse proportion pressure valve set, inverse proportion valve action and reduce control air volume, air compressor air intake valve servo cylinder valve stem thrust reduced, in under the action of spring force, the valve stem retraction, when the spring force and the gas cylinder thrust balance, the valve stem is in a state of half open, sliding-vane compressor into the air to gas phase equilibrium and system.
Inverse proportion valve adjustment is more simple, but in order to realize the servo cylinder sensitive action you need to adjust many times, the inverse proportion valve's purpose is to adjust air pressure moves away from the pressure switch on the floor are 0.02 MPa when the inverse proportion valve action, in order to reduce or increase the sliding-vane compressor into the air to make the air intake valve up or down accordingly, adjust the air compressor capacity in advance, in order to decrease the number of empty heavy load for sliding vane compressor. Inverse proportion valve clockwise to adjust have increased servo cylinder air inflow effect, on the other hand, is to reduce the volume.
Inverse proportion valve is installed in front of the intake valve servo cylinder.
When the system pressure to inverse proportion valve action. Adjusting the servo cylinder, servo cylinder adjusting inlet butterfly valve opening Angle, so as to adjust the volume, displacement.
Inverse proportion valve connection thread: G1/4, vent size is 0.8 MM and 1.0 MM, two kinds of inverse proportion valve in the compressor system control into the air intake valve, reducing motor load achieve energy saving effect.
