Wuhan far located in Hongshan District of Wuhan City, is a professional manufacturer of vacuum breaker, the company invested funds this year to open his own mold design and manufacture of self brand far Ming Fung vacuum breakers, vacuum breakers comparable quality imported from Italy, brass, temperature 110 degrees, the pressure 16bar, when positive pressure leak tightness, vacuum seal when the time to open the intake to the system eliminate vacuum, each vacuum breakers have been factory strict inspection, the only country able to provide third-party testing organizations test report issued by the company, sales of the first vacuum breaker China, good reputation, is now facing the wholesale destruction far Ming Fung vacuum is, the sale of a vacuum breaker one-year warranty, genuine vacuum breaker, trustworthy. Far Ming Fung vacuum breaker, fill the gaps, solve import vacuum breakers on the market price of your users want to use but could not afford problems. Wuhan far Ming Fung manufacturing vacuum breaker, it is the real vacuum breaker production Manufacturers, due to the mass production, vacuum breaker can do the lowest price, all of the company sold vacuum breakers year replacement product quality problems, is a trustworthy company vacuum breaker Far Ming Fung is the vacuum breaker the first domestic vacuum breaker. Vacuum breaker types: vacuum breaker is an automatically eliminate water pipes vacuum, effectively preventing siphon backflow device, built according to standard CJ / T 324-2010 type vacuum breaker into the atmosphere type, pressure type and hoses type. Atmospheric type vacuum breaker English atmospheric vacuum breaker, a vacuum breaker may be introduced at atmospheric pressure less than atmospheric pressure to the inner pipe. When the water barrier and the atmosphere of the vacuum breaker, mainly in the form of a single intake type; atmospheric type vacuum breaker of local head loss should 0.02MPa, the local head pressure vacuum breaker loss should be 0.035 ~ 0.045MPa. Atmospheric type vacuum breaker set features: 1. On the downstream piping is no vacuum breaker off valves and control valves. 2. Pre-control valve to control the work of water downstream appliances. 3. Stop the water downstream water appliances, vacuum breakers are not under pressure. 4. Freeze possible, set at the bottom of the drain valve and connecting pipe surface drainage facilities. 5. The vacuum breaker qi flow should be greater than the upstream pipeline 3m / s flow velocity when. Pressure-type vacuum breakers a loss of pressure in the water supply pipeline to a certain set pressure first stop, followed after introducing a vacuum atmosphere to prevent backflow siphon vacuum breaker suitable for continuous pressure conditions of the vacuum breaker, The main form is divided into single - inlet and outlet non-return type. Pressure-type vacuum breakers set features: 1. Set off valve or control valve to control the downstream water apparatus operating in the downstream pipe of a vacuum breaker. 2. Stop the water downstream water appliances, vacuum breaker by pressure upstream. 3. When the water supply is not allowed access, should be connected between the vacuum breaker valve repair piping should be set. 4. Freeze possible, set at the bottom of the drain valve and connecting pipe surface drainage facilities. 5. The vacuum breaker qi flow should be greater than the upstream pipeline 3m / s flow velocity when. Hose-type vacuum breaker English hose connection vacuum breaker, a special connection hose vacuum breakers, dedicated to the outlet connector hose vacuum breakers, mainly in the form of import-return type. Hose type pipe vacuum breaker set features: 1. vacuum breaker located upstream of the control valve hose should select a single top tube pressure vacuum breaker. 2. The vacuum breaker is located downstream of the control valve in the hose, should choose to import non-return-type vacuum breaker. 3. Freeze possible, set at the bottom of the water pipe vent valve, water control valve and surface drainage facilities. 4. Simple fire water pressure pipe riser or other heterogeneous water and drinking water pipeline connections should be provided separately backflow prevention device. Vacuum breaker set 1) from the cell or drinking water pipes in the building directly connected to the following pipes, vacuum breaker should be set on the water pipes. a. When the air gap swimming pool, amusement pools, water features pool, circulating cooling water collection ponds and other water-filled or water pipe outlet and overflow water level is less than 2.5 times the diameter of the outlet, in which the charge (s) water pipes on; b do not contain chemicals green sprinkler system, when the nozzle is underground or automatic lift, at the borders of its water pipes;. c Fire (hose) reel;.. d flushing water outlet hose junction mouth with water pipes. 2) in the water supply riser to the top to be provided and the exhaust valve vacuum breaker vacuum breaker Yueyang Yueyang Yueyang vacuum breakers installed vacuum breaker maintenance
