Abstract
The utility model discloses a kind of fire pump adapter, it mainly comprises body, flange bending, water outlet mouthpiece pipe, safety valve, check-valves, discharging valve and gate valve, it is characterized in that check-valves is arranged in flange bending, be made up of flap, valve clack sealing ring, pressing plate, valve rod, valve seat, spring, packing ring and valve stem nut successively, valve rod one end connects flap, the other end is equipped with valve stem nut and nut collar, and pressing plate is fixed on flange bending, between pressing plate and packing ring, spring is housed.Check-valves of the present utility model is arranged in fire pump adapter, compares the check device of independent annex, avoids check-valves neglected loading, anti-loaded problem, can save cost simultaneously, reduces installation workload.
Description
Technical field
The utility model relates to a kind of fire plant, particularly a kind of fire pump adapter.
Background technology
Fire pump adapter is for connecting fire fighting truck, power pump to the interface of pipe network water supply in building, when scene of a fire indoor fire-fighting water pump break down or indoor fire-fighting water-supply shortages time, just need with fire fighting truck or power pump fire hydrant, fire cistern or open water supply water intaking outdoor, by fire pump adapter, water is delivered to pipe network in house, scene of a fire water in supply chamber, make indoor fire hydrant or other water system extinguishing device, obtain sufficient pressure water source.
The structure of fire pump adapter is primarily of compositions such as body, flange bending, water outlet mouthpiece pipe, safety valve, check-valves, discharging valve, gate valves, and the assembling of general fire pump adapter should be undertaken by the order of interface, body, connecting tube, check-valves, blow-down pipe, control valve.Wherein check-valves is used to elimination water hammering, at present general it be arranged on the outside of fire pump adapter as an independent annex, and install to noting ensureing that fire demand water enters system from connector, as installed instead, cannot to the serious problems of moisturizing in system by causing; And at the siamese fire department connection used to skyscraper, check-valves is not installed, cause when pressurizeing examination water, when fire fighting truck pump stops pressurizeing, the water pot of fire fighting truck breaks up by the water backflow of high pressure fire fighting pipe network.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of check-valves to be contained in fire pump adapter in fire pump adapter, solves check-valves neglected loading, anti-loaded problem.
The utility model realizes like this, a kind of fire pump adapter, it mainly comprises body, flange bending, water outlet mouthpiece pipe, safety valve, check-valves, discharging valve and gate valve, it is characterized in that check-valves is arranged in flange bending, be made up of flap, valve clack sealing ring, pressing plate, valve rod, valve seat, spring, packing ring and valve stem nut successively, valve rod one end connects flap, the other end is equipped with valve stem nut and nut collar, pressing plate is fixed on flange bending, between pressing plate and packing ring, spring is housed.
Its principle is: on water inlet mouthpiece, carry out fire_fighting pipe network in control room by gate valve link with extraneous, when being rotated counterclockwise gate valve, fire pump makes siamese fire department connection be full of press water by water inlet interface, and pressure water source flows to indoor fire-fighting pipe network by check-valves and valve base chamber passage.Safety valve has been set up to nominal pressure value when product export.It can ensure that in pipeline, hydraulic pressure or fire pump discharge pressure are not more than 1.70 ± 0.05MPa, when pressure is more than 1.70 ± 0.05MPa, and safety valve action, releasing pressure automatically, thus the object realizing safety water supply.Check device in flange bending, its effect is that anti-sealing (or foam solution) flows backwards, and eliminates water hammer, fire pump can be worked safely and effectively.
The beneficial effects of the utility model are, check-valves is arranged in fire pump adapter, compare the check device of independent annex, avoid check-valves neglected loading, anti-loaded problem, can save cost simultaneously, reduce installation workload.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of check-valves.
In the drawings, 1, body 2, flange bending 3, water outlet mouthpiece pipe 4, flap 5, valve rod 6, water inlet interface 7, gate valve 8, discharging valve 9, safety valve 10, valve clack sealing ring 11, pressing plate 12, valve seat 13, spring 14, nut collar 15, valve stem nut.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of fire pump adapter, it mainly comprises body (1), flange bending (2), water outlet mouthpiece pipe (3), safety valve (9), check-valves, discharging valve (8) and gate valve (7), it is characterized in that check-valves is arranged in flange bending (2), successively by flap (4), valve clack sealing ring (10), pressing plate (11), valve rod (5), valve seat (12), spring (13), nut collar (14) and valve stem nut (15) composition, valve rod (5) one end connects flap (4), the other end is equipped with valve stem nut (15) and nut collar (14), pressing plate (11) is fixed on flange bending (2), spring (13) is housed between pressing plate (11) and nut collar (15).
When using this fire pump adapter, be rotated counterclockwise gate valve (7), fire pump makes siamese fire department connection be full of press water by water inlet interface (6), and pressure water source flows to water outlet mouthpiece pipe (3) by passage between check-valves flap (4) and valve seat (12), resupplies indoor fire-fighting pipe network.Safety valve (9) has been set up to nominal pressure value when product export.It can ensure that in pipeline, hydraulic pressure or fire pump discharge pressure are not more than 1.70 ± 0.05MPa, when pressure is more than 1.70 ± 0.05MPa, and safety valve (9) action, releasing pressure automatically, thus the object realizing safety water supply.Check device in flange bending (2), its effect be anti-sealing (or foam solution) indoor pipe network flow backward to fire pump, eliminate water hammer, fire pump can be worked safely and effectively.
