Non-negative-pressure pressure compensation water supply equipment
The invention discloses non-negative-pressure pressure compensation water supply equipment, which comprises a steady flow tank, wherein a municipal running water inlet and a water inlet pipeline interface are formed in the steady flow tank; the water supply equipment further comprises a pressure compensation tank which is arranged in a mode of being separated from the steady flow tank; one end of the pressure compensation tank is communicated with the municipal running water inlet in the steady flow tank by virtue of an exhausting and water replenishing device, and the other end of the pressure compensation tank is connected to the tail end of a water inlet pipe by virtue of a pressure compensation water replenishing device; the pressure compensation tank comprises a capsule body, a negative pressure inhibiting device and a vacuum inhibiting device; the capacity Vn of the pressure compensation tank is equal to (V0-Vt)/u, wherein u ranges from 0.35 to 0.55, V0 is the optimized design capacity of a steady flow regulator, Vt stands for national standard design capacity of the steady flow regulator, and capacity ratio of the steady flow tank to the pressure compensation tank is 6 to 4. The non-negative-pressure pressure compensation water supply equipment disclosed by the invention is simple in structure, compact in integral structure and has double-protection function, and all functional parts are externally arranged; the water supply equipment is convenient to discover damaged components and is capable of overhauling timely; and the water supply equipment, when achieving non-negative-pressure protection, air isolation and pressure compensation functions, is capable of greatly improving operating reliability thereof.
