Uncomfortable when opening and closing speed of the actuating system a management way of the pressure rise or decline suddenly, when the pressure on appreciation enough will actuating tube cracks. Urban central heating system has been gradually replaced by household type spread warm furnace, Beijing, shenyang and other cities have so far or are building a large central heating systems, henceforth the central heating system will progress in the direction of the large-scale and complication. Check valve in the heating system is a management way a very shut device, the check valve installation position, the structure and parameter of closed curve for the safety of the heating system and stung by sex has very big effect. If the check valve using suitable; Can act as ice hammer against the effectiveness of protection; But if not appropriate to use, can't more than Marine Industrial Valves for heating have tried my best to take care of the utility, and will in the heating system a management line moved very hot water. Reasonable for the factory to ensure the safety of system, be sure to choose the way the check valve and closed curve, make its have the effect of water hammer. From the perspective of fluid transient motion; Only to the requirement of check valve under the interruption of power to open or closed, and should be based on the flow state in the heating pipe has certain requirements for opening and closing speed. This kind of large-scale heating grand central heating systems, water hammer accident happened once destructive power is strong, serious consequences, because this is important to take active preventive treatment method, try to loss and avoid the occurrence of water hammer. Q: check valve water hammer effect answer: with the progress of the national economy and people's livelihood live level increasing. For the check valve water hammer in heating system of utility of the practical significance of the research have a very tight and academic significance. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
