Honeywell automatic exhaust valve E121

I. Overview Honeywell automatic exhaust valve lift of the float with the liquid level force linkage exhaust opening and closing, to achieve automatic exhaust purposes. When the gas is collected into the valve body, due to the air pressure, the valve body surface down, the float fall, it fell to the lower limit, the linkage lever system, the exhaust valve opens the valve port and release the gas under pressure, the results for the valve followed by reduction of pressure inside the liquid move, the float rises, the elastic force of the spring, the exhaust port is closed. Such gas will continue to be collected, emissions, and then collected before it is discharged to complete the automatic discharge process piping and equipment systems. Second, the structure brass body, bonnet, float made of high temperature composite materials. Removable bonnet. Third, the characteristics 1, sealing performance, high temperature resistant synthetic rubber ring pad, the complete elimination of leakage troubles. 2, large displacement: displacement and system pressure proportional. 3, easy to maintain: Direct unscrew the valve body wash, does not affect normal operation. Various Fourth, the application range of heating system radiators, pipes and boilers, air conditioning systems, etc. requires the use of gas-water separator occasions. Fifth, the various parameters unit of length (mm) Name Number allowable pressure medium temperature properties of the medium weight D1 D2 H h E121-Z1 / 2 "A 0.98MPa (10kg / cm2) ≤110 ℃ 0.17kg must not be mineral oil or oily liquid 15,477,915 6, installation Precautions 1, the first shutoff valve installed vertically in the pipeline, and then use a wrench to tighten the valve shut-off valve on the vertical above the valve body should be set aside more than 10cm space for maintenance. 2. To install the pipe diameter of 3/4 inch, 1/2 inch change simply adding 3/4 inch bushing. 3, if not exhaust, please unscrew the body, remove dirt re Installation Note: Attachment blocking valve E121-Z 1/2 inch, brass, diameter of 1/2 inch.
