Abstract
The utility model belongs to fire gear technical field; disclose a kind of water pump system protective gear; its technical characteristics is: comprise the body with water intake and water outlet, described body is provided with butterfly shaped check valve, the body between water outlet and butterfly shaped check valve is provided with safety valve.Water pump system protective gear provided by the utility model; when the water in pipeline produce violent fluctuation there is water hammering time; butterfly shaped check valve can avoid the aqueous reflux in pipeline to return in fire-fighting truck, thus the impact of the temporary high-pressure protecting fire service pump to produce from water hammer.Meanwhile, the safety valve between water outlet and butterfly shaped check valve, will open when the pressure in pipeline exceedes the pressure of safety valve setting, be fallen by unnecessary earth pressure release in time, carry out pressure release, thus protect the safety of water-band, hydraulic giant and water knockout drum on whole circuit.
Description
Technical field
The utility model belongs to fire gear technical field, particularly relates to a kind of water pump system protective gear.
Background technique
In Fire Fighting in Tall Buildings process, the vertical hose laying of frequent needs is to lower one deck of fire floor or lower two layers, when inside fire attack combatant closes suddenly hydraulic giant or other valve, press down or have vehicle to roll fire-extinguisher water hose, the water in pipeline can be caused to produce violent fluctuation, namely water hammering, easily causes damage to fire water pump.
Model utility content
The technical problem of solution of the present utility model is just to provide one and can eliminates water hammering, fire-fighting is pumped up to the water pump system protective gear of protective action.
The technical solution adopted in the utility model is: comprise the body with water intake and water outlet, described body is provided with butterfly shaped check valve, the body between water outlet and butterfly shaped check valve is provided with safety valve.
Its additional technical feature is: described safety valve is one or two.
Water pump system protective gear provided by the utility model, is arranged between the male mouth of 80 fire-extinguisher water hoses and female mouth, and in using process, this device is positioned between fire-fighting truck and water knockout drum.When inside fire attack combatant closes suddenly hydraulic giant or other valve; press down or have vehicle to roll fire-extinguisher water hose; the water in pipeline is caused to produce violent fluctuation when there is water hammering; butterfly shaped check valve can avoid the aqueous reflux in pipeline to return in fire-fighting truck, thus the impact of the temporary high-pressure protecting fire service pump to produce from water hammer.Meanwhile, the safety valve between water outlet and butterfly shaped check valve, will open when the pressure in pipeline exceedes the pressure of safety valve setting, be fallen by unnecessary earth pressure release in time, carry out pressure release, thus protect the safety of water-band, hydraulic giant and water knockout drum on whole circuit.As required, safety valve is one or two.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model water pump system protective gear.
Embodiment
Be described in further details below in conjunction with the concrete structure of accompanying drawing to the utility model water pump system protective gear.
As shown in Figure 1, the utility model water pump system protective gear comprises body 1, and body 1, with water intake 2 and water outlet 3, body 1 is provided with butterfly shaped check valve 4, and the body 1 between water outlet 3 and butterfly shaped check valve 4 is provided with safety valve 5.
Water pump system protective gear provided by the utility model, is arranged between the male mouth of 80 fire-extinguisher water hoses and female mouth, and in using process, this device is positioned between fire-fighting truck and water knockout drum.When inside fire attack combatant closes suddenly hydraulic giant or other valve; press down or have vehicle to roll fire-extinguisher water hose; the water in pipeline is caused to produce violent fluctuation when there is water hammering; butterfly shaped check valve 4 can avoid the aqueous reflux in pipeline to return in fire-fighting truck, thus the impact of the temporary high-pressure protecting fire service pump to produce from water hammer.Simultaneously; safety valve 5 between water outlet 3 and butterfly shaped check valve 4, will open when the pressure in pipeline exceedes the pressure of safety valve 5 setting, be fallen by unnecessary earth pressure release in time; carry out pressure release, thus protect the safety of water-band, hydraulic giant and water knockout drum on whole circuit.As required, safety valve 5 is one or two.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the structure of the utility model water pump system protective gear, just drops on the scope of the utility model protection.
Claims (2)
1. water pump system protective gear, comprises the body with water intake and water outlet, it is characterized in that: described body is provided with butterfly shaped check valve, the body between water outlet and butterfly shaped check valve is provided with safety valve.
2. water pump system protective gear according to claim 1, is characterized in that: described safety valve is one or two.
