Abstract
The utility model provides a shuttle-type unit connector of a fire-proof water pump, which integrates a safety valve, a check valve and a water discharging valve, and the utility model is provided with a windowing cylinder valve clack. The utility model has the advantages of steel saving, small area occupation, simple structure and good sealability.
Description
The utility model relates to a kind of fire pump adapter, particularly relates to a kind of fire pump adapter that has safety valve, safety check and discharging valve.
Original fire pump adapter is a kind of device that is connected in series successively by independent safety valve, safety check, discharging valve and gate valve (stop valve).A kind of like this combining form of ready-made stack, it is more to expend steel undoubtedly, and it is bigger to take ground.And with regard to the function of fire pump adapter, have only gate valve when the maintenance siamese fire department connection, because of the needs of pipeline cutout; outside must being provided with separately; all the other functions (pressurized overflow is crossed in unidirectional conducting, shuts down to discharge water) can be realized by " one " multifunction valve fully.
Therefore, the purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of compact structure, fire pump adapter that floor space is little are provided.Adopt this fire pump adapter to make numerous and diverse designs simplification of original safety valve in the prior art, safety check, discharging valve serial connection, and, floor space is reduced greatly.It is compared with the old-fashioned fire pump adapter of same specification, can save 60% floor space and 25% steel.Simultaneously, reduce sealing surface, improved performance.
In order to achieve the above object, the utility model provides a kind of fire pump adapter, it comprises valve body, check-valve cap, safety valve, safety check and discharging valve, described safety valve, safety check and discharging valve are arranged on the structural member that is made of check valve body and check-valve cap, form an integral valve door.
In the fire pump adapter that the utility model provides, safety valve is connected by screw thread with check-valve cap, is provided with discharging valve at the turnover pipeline lowest part of safety check, and it is connected by screw thread with safety check.
In the fire pump adapter that the utility model provides, be provided with the non-return flap in the safety check, the end face seal of non-return flap, and be provided with along axially extended cylindrical body shuttle cover.
In the fire pump adapter that the utility model provides, put at described cylindrical body shuttle and to be provided with water passage hole.
In the fire pump adapter that the utility model provides, safety check is the vertical lift type safety check.
In the fire pump adapter that the utility model provides, the inside nominal diameter of turnover pipeline is 100mm or 150mm, and nominal pressure is 16kg/cm

Below in conjunction with the embodiment of Figure of description, specify 26S Proteasome Structure and Function of the present utility model.
Fig. 1 is the positive view of fire pump adapter of the present utility model.
In accompanying drawing 1, safety valve 1 places (specification of safety valve can arbitrarily be matched according to the specification requirement of siamese fire department connection) on the check-valve cap 2, and they interconnect by screw thread.Turnover pipeline lowest part at safety check 4 is provided with discharging valve 5, and it is connected with the valve body 6 of safety check 4 by screw thread.Two discharging valves 5 are set altogether, only illustrate one in the accompanying drawing.Safety check 4 is vertical lift type safety check, wherein is provided with non-return flap 3, is provided with Sealing at the end face of described non-return flap 3.And, be provided with along axially extended cylindrical body shuttle cover 7 at the end face of non-return flap 3.On described cylindrical body shuttle cover 7, be provided with water passage hole.The inside nominal diameter of the turnover pipeline of safety check 4 is 100mm or 150mm, and nominal pressure is 16kg/cm

Press water is flowed into by the left end inlet of safety check 4, promotes flap 3 and rises.Because flap 3 is the window formula of the carrying shuttle nested structure of end face seal, just make fire pump adapter of the present utility model have function along with the Lift of the big or small auto-control flap 3 of water pressure.During safety check 4 work, because of the existence of water pressure, force the spring pressurized of discharging valve 5, discharging valve 5 cuts out automatically.When safety check 4 stopped into water, under the effect of hydrostatic circuit power, the flap 3 of safety check 4 was closed.When the water pressure on the water return pipeline surpassed specified value, the flap of safety valve 1 was opened, and excessive water overflows from the outlet of safety valve 1.
Claims (6)
