Abstract
The utility model relates to a connector for connecting the fire fighting water supply system in the high building with the fire fighting pump vehicle, which belongs to a fire fighting switch device. The utility model is improved on the basis of the connector of fire fighting pump originally imported from Britain. The switch one-way valve of the connector produced by Britain is in the pressure spring type; when the valve is in the state of opening, the pressure drop of the water pressure has big loss, and the phenomenon of blockage is easy to appear when the valve resets. The utility model adopts the plate type negative pressure valve to replace the pressure spring type valve, having the advantages of small water stream pressure drop, no blockage when the valve resets and convenient repair and maintenance.
Description
The utility model is a kind of high-rise building bottom that is installed in, and is used for the coupling arrangement of waterworks for firefighting in UNICOM's fire water pump truck and the high-rise building, belongs to fire-fighting equipment.
In order in time to put out the intensity of a fire, all high-rise buildings all are furnished with waterworks for firefighting, and general water-supply systems are low pressure, are difficult to adapt to the needs of higher level building fire fighting supply.The way that addresses this problem is to give the pressurization of high-rise building water system with the fire water pump truck by connecting a connector.The present connector that uses mainly adopts the SQB-100 type connector that is installed within the walls, and this device profile is thick, and difficulty is installed, and water pressure is lost greatly during use, and the product consumptive material takes the cost height.Recently introduce a kind of connector from Britain, its compact conformation, shape is small and exquisite, adopts compression spring non-return valve door to make switch.Behind the fire pump water supply start, High-Pressure Water compression spring backs down one-way cock, gives water system supercharging in the floor.Because High-Pressure Water is just opened one-way cock after overcoming spring force, thereby the water inlet droop loss is bigger; And one-way cock is to do axially-movable by central pivot point, and its stroke distances is big, occurs the jam phenomenon easily, can not close from horizontal reset.In addition, connecing cover and will just unloading from outside reinforcing with specific purpose tool of this connector makes troubles for the installation and the maintenance work of valve.
Main purpose of the present utility model is to provide a kind of droop loss little, and secondly the fire pump adapter that valve can jam is the convenient for maintaining maintenance.
The technical solution of the utility model is to solve like this: adopt a disk rubber negative one-way valve door, its fulcrum is fixed on to connect and puts, and connects cover and connects with main body by screw thread is identical, the valve fulcrum is in connects the cover top, and valve freely suspends.Connecing cover has an inclination angle with one-way cock applying end plane, place and horizontal plane, and valve utilization deadweight and inside and outside hydraulic pressure pressure reduction seal water system and extraneous path.Consider that dismounting is easy to maintenance, the inner round wall that connects cover is provided with the bearing-surface of accepting torsion.
Embodiment of the present utility model will provide in conjunction with the accompanying drawings.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 for the utility model along Figure 1A-A to the one-way cock structure chart of analysing and observe.
Fig. 3 connects the axial vertical view of cover for the utility model.
With reference to Fig. 1, connect cover 2 and coincide by screw thread and main body 7, interface 1 overlaps 2 and connects with connecing by screw thread.With reference to Fig. 2, one-way cock 3 is circular, adopts dull and stereotyped rubber to be stamped to form, and the one end is by screw 5, and pressing plate 6 is fixed on and connects on cover 2 sealed ends.Non-return flap 4 is steel or copper round sheet, is bonded to one with valve 3, with the damping intensity of reinforcement one-way cock, and makes counterweight and uses.Whole valve 3 can unload with connecing cover 2 with non-return flap 4.Connect cover 2 and become 80～88 degree angles with horizontal plane with the plane, applying end place of valve 3.Connect the cover be screwed into main body after, the fulcrum of valve 3 be in the top, whole valve freely suspends.Valve utilizes inner pipe water pressure and deadweight to rest on and connects on the cover seal face, seal building waterworks for firefighting and extraneous path automatically.After fire pump and the interlock of this connector interface, High-Pressure Water is pushed one-way cock 3 open and is entered supercharging in the building waterworks for firefighting; In case after fire pump pressure disappeared, one-way cock relied on inner pipe water pressure and the deadweight cut-out path that automatically resets.With reference to Fig. 3, consider that dismounting is easy to maintenance, connecing on cover 2 the inner round wall has two bearing-surfaces 8 that bear torsion, and it is directly afterburning that the interior angle wrench can insert the back from the water inlet direction.Its rotation is unloaded.
The utility model water inlet area is big, and droop loss is little, and valve opening and closing is flexible, and is convenient to maintenance, and the whole connector little show window of can packing into embeds within the walls, takes up an area very little. Improvement for fire-fighting equipment is upgraded, and has a significant effect.
Claims (3)
1, a kind of connector that is used for waterworks for firefighting in UNICOM's waterproof pump truck and the high-rise building, comprise main body, interface, connect cover, one-way cock, it is characterized in that described one-way cock 3 is to form with sheet rubber and metal non-return flap 4 bondings, the fulcrum of sheet rubber is fixed on the top that connects cover 2 sealed ends, and remainder freely suspends.
