2、说明 Instructions
OTRV 油温调节阀是一个制冷用的三通阀,通过对螺杆压缩机或离心压缩机润滑油系 统中热油和冷油进行混合用于维持压缩机的油温处于稳定的水平,也可以作为方向换 向阀使用。
阀体接口分A\B\C 标识,作为油温调节阀用时,A 接压缩机,B 接高温油,C 接冷油, 当温度达到感应元件的温度时,自动控制B 和 C 的流量,从而达到调节油温的目的。 作为方向换向阀使用时, A 为入口,B 接压缩机管路,C 接冷油。
The OTRV is a three-way valve for refrigeration.it is used to maintain the oil temperature of the compressor at a stable level by mixing the hot oil and cold oil in the lubricating oil system of the screw compressor or centrifugal compressor.It can aso beused Used as a directional control valve.
The valve body interface is marked with A\B\C.When used as an oil temperature regulating valve,A is connected to the compressor,B is connected to the high temperature oil,and Cis connected to the cold oiL When the temperature reaches the temperature of the sensing element,the flow of B and C is automatically controlled.5o as to achieve the purpose of adjusting the oil temperature When used as a directional reversing valve,A is the inlet, B is connected to the compressor pipeline,and c is connected to the cooling oiL.
