ã€Structure and use】 Multifunctional pump control valve is composed of main valve 1, control valve 2, filter 3 and so on. For industrial and mining, business, high-rise buildings in the water supply and drainage system with a direct stop valve, check valve, electric valve and water hammer eliminator four functions. Especially suitable for supporting automatic water control system, without the need of electrical controller and external power, according to the conventional automatic opening and closing, with a quick closure, slow closing and absorbing cavity three kinds of functions to prevent and eliminate water hammer, which can effectively improve the system safe and reliable Sex. Meet the system engineering equipment automation control requirements. ã€Main technical parameters】 Nominal pressure 1.0MPa 1.6MPa 2.5MPa Shell test pressure 1.5MPa 2.4MPa 3.75MPa Seal test pressure 1.1MPa 1.76MPa 2.75MPa Working temperature ≤ 80 ℃ Water hammer peak ≤ 1.5 times (working pressure) Minimum working pressure P1 ≥0.07MPa Slow closing time 3 ~ 120S (adjustable) Pressure loss ≤0.03MPa (flow rate 2M / S) Applicable medium water ã€Main appearance size】 DN (mm) L (mm) H 240 270 Blue Connection Size: PN1.0MPa, PN1.6MPa Press GB4216.

Twin Shaft Concrete Mixers
The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.
