Description
Technical field
The utility model relates to fire service inventory, is specifically related to a kind of and-regulated fire hydrant on the ground.
Background technology
All fire plug is had everywhere, for fireman provides water for fire extinguishing in rescue operations in city.Main Function controls combustible, isolated oxidizer, elimination ignition source.Fire fighting system comprises, outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and what have also has automatic sprinkler fire-extinguishing system, water cannon system, gas extinguishing system, fiery spy system, spraying system etc.Fire plug mainly implements fire extinguishing for fire fighting truck from municipal water supply pipe network or the water intaking of outdoor fire fighting waterline network, also directly can connect water-band, hydraulic giant goes out above-water method.
At present along with the development of highrise building, there is various pressure-reduced and-regulated type hydrant, these pressure-reduced and-regulateds due to complex structure, manufacturing cost is higher, and thus price is very expensive, adds building costs.
Summary of the invention
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of and-regulated fire hydrant on the ground, comprise key and bolt, described bolt-through is in key, and its innovative point is: also comprise motor, nut, spring, portable plate, large valve plate and little valve plate; The output shaft of described motor and the power shaft axle of bolt link together; The soffit of described bolt is fixedly connected with large valve plate, and the soffit of described large valve plate is fixedly connected with little valve plate; Described nut is fixedly connected on the centre position of bolt; Described portable plate is movably connected on bolt, and is positioned at the lower end of nut, and described portable plate is connected with nut by spring; Described portable plate there is several through hole with center of circle mode array.
As preferably, described spring is disk spring.
As preferably, described motor is servomotor, stepper motor or variable-frequency motor.
As preferably, described large valve plate is in the form of annular discs.
As preferably, described little valve plate cross section is trapezoidal shape.
The beneficial effects of the utility model:
1, its reasonable in design of the utility model, modern design is unique, and simple to operate, easy to use, spring is adopted as disk spring, and rigidity is large, and buffering vibration absorption ability is strong.
2, the utility model arranges portable plate, and arranges through hole on portable plate, can reach aperture turnover current, reach the effect of decompression and pressure regulation.
3, the cross section of the little valve plate of the utility model adopts trapezoidal shape, can make it have guidance quality.
