Venturi tube flowmeter flow meter is used to test fire pump flow and performance. When the flowmeter to the pipe sanitary valves before and after the meter has a minimum length of straight pipe access requirements, see below. Meter maximum range = 2 × required to measure the maximum range value Note: This product brand GERAND. Hubei Chong Mechanical and Electrical Equipment Co., Ltd. Anyuan virtue of the NFPA standard specifications and FM deep understanding of customer service for the origin uphold the valve industry, the pursuit of continuous innovation and improvement of its own after years of rapid development has become FM / UL certification of fire products in the field of the most active valve, most efficient supply service providers. Stainless steel valves when wet or dry start to start the system, the use of K = fast response closed nozzle 80 as a fire detection elements, and cross-fire with closed nozzle disposed in the protected area. Fire detection components as early action fast response sprinklers, wet start-up mode deluge valve diaphragm chamber pressure discharge water from the sprinklers start operation, the dry sprinkler boot mode from the start of the discharge operation starts within the dry pipe network pressure, thereby opening Dry start control valve diaphragm chamber discharge pressure of the water, the pre-action valve is open to the water pipe network. Year Anyuan Industrial (Figure) _ _ Hongshan valve pneumatic valve by the Hubei Chong Anyuan Electrical Equipment Co., Ltd. to provide. Hubei Chong Anyuan Electrical Equipment Co., Ltd. (www.hbcay119.com) (www.hbcay119.com) strong, credible, in Wuhan, Hubei fire equipment industry has accumulated a large number of loyal customers.
