Abstract
A kind of Multifunctional hydrant adopting spherical valve core to make valve blocking piece, comprise key 8, spherical valve core 7, Pressure gauge 6, is characterized in that: in hydrant body 8, use spherical valve core 7 as fire hydrant valve blocking piece, described by band screw mandrel spanner 1, nut 2, tappet 4 and spherical valve core 7 combined operation, can be used for opening and closing fire hydrant, and by spherical valve core 7, steam vent 3 and nut 2 automatic vent, what Pressure gauge 6 was placed in key 8 closes on water cavity, be convenient to observe hydraulic pressure.The utility model integrates fire-fighting, exhaust, hydraulic pressure display three zones, particularly outstanding, with spherical valve core as valve blocking piece, greatly can extend the service life of fire hydrant, manufacture and maintenance cost low, be worthy to be popularized.
Description
Technical field
The utility model is the Multifunctional hydrant adopting spherical valve core to make valve blocking piece, relates to supply water management and administration of the prevention and control, belongs to feedwater, fire-fighting domain.
Background technology
Fire hydrant is fire-fighting infrastructure, in urban fire control, it is connected with city tap-water water supply line, and it is closeer to distribute on water supply line, most area at home, fire hydrant is all installed by water supply department, because the installation cost of fire hydrant and affiliated facility thereof is larger, belong to building again and execute, larger economic pressures are brought to water supply department, especially conventional fire hydrant ubiquity nut, screw mandrel and valve plate short, extremely flimsy phenomenon in service life, cause fire hydrant not opened or leak, and gives the great operating pressure of water supply department especially; Water supply department is the problem solving water supply network exhaust, reduce the maintenance cost of water supply network, avoid producing contradiction because of gas red switch water meter with water user, be convenient to the operation conditions understanding city water supply pipe network, need the position water supply line is suitable that automatic exhaust steam valve and Pressure gauge are installed, so that the water pressures in the gas drained in water supply line and understanding each region, city, the installation of this two facility, adds the financial burden of water supply department equally; On the other hand, the transfer of staff members of various places fire department is frequent, as being unfamiliar with the topography and geomorphology in this city, the hydraulic pressure distribution in each region, city is not understood, just can not overall arrangement when breaking out of fire, often incur loss through delay attack time, result in greater loss to the people's lives and property.
Summary of the invention
For prior art, for solving the demand of water supply department, problem to be solved in the utility model fire hydrant, automatic exhaust steam valve and Pressure gauge will be combined together, spherical valve core is adopted to produce a kind of Multifunctional hydrant as fire hydrant valve blocking piece, extend the service life of fire hydrant, meanwhile, make fire hydrant possess fire-fighting, pipeline air exhaust water and pressure measuring function, reduce installation and maintenance cost, simple and practical.
For solving the problem, the technical scheme that the utility model is taked is: a kind of Multifunctional hydrant adopting spherical valve core to make valve blocking piece, comprise key, band screw mandrel spanner, nut, tappet, spherical valve core, steam vent, it is characterized in that the combined operation mechanism be made up of band screw mandrel spanner, nut, tappet and spherical valve core accessory opens and closes fire hydrant, and by spherical valve core, steam vent, nut automatic vent; What Pressure gauge was placed in key closes on water cavity, is convenient to observe hydraulic pressure; The described fire hydrant integrating fire-fighting, exhaust, pressure measuring function, is characterized in that adopting spherical valve core to open and close the link operation manner of fire hydrant as valve blocking piece with the combined operation mechanism of band screw mandrel spanner, nut, tappet, spherical valve core accessory composition in key.
Good effect of the present utility model is: the service life that can extend fire hydrant; Two can discharge the gas in water supply line and key in good time, reduce pipeline vapour lock, protection water supply line, ensure that gage pressure display is accurate; Three can be water supply department provides water pipe pressure data, is convenient to management, can be the hydraulic pressure distribution situation that fire department provides each region, city, be convenient to overall arrangement during breaking out of fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (longitudinally analysing and observe)
Number in the figure: 1, be with screw mandrel spanner, 2, nut, 3, steam vent, 4, tappet, 5, draining valve, 6, Pressure gauge, 7, spherical valve core, 8, key.
Detailed description of the invention
See Fig. 1, a kind of Multifunctional hydrant adopting spherical valve core to make valve blocking piece, comprise key 8, band screw mandrel spanner 1, nut 2, tappet 4, spherical valve core 7, steam vent 3, Pressure gauge 6, detailed description of the invention: when opening use fire hydrant, band screw mandrel spanner 1 is screwed in nut 2, along with screw-in depth strengthens, band screw mandrel spanner 1 promotes tappet 4 and depresses spherical valve core 7, and fire hydrant is opened; When closing fire hydrant, screwed out by band screw mandrel spanner 1, spherical valve core 7 rises under buoyancy of water and hydraulic pressure effect, promotes up by tappet 4, when spherical valve core 7 walks to valve port, under the effect of hydraulic pressure, by valve shut, closes successfully; When chance close in water cavity have gas time, spherical valve core 7 falls, and by means of hydraulic pressure effect, gas is discharged by valve port, steam vent 3, nut 2; After chance water supply line is emptying, water supply line and fire hydrant close gassy in water cavity, then during water filling, each utility model is all in exhaust condition, can drain gas in pipelines rapidly, drain rear automatic closedown; Close on water cavity at key 8 and Pressure gauge 6 is set, this hydraulic pressure of observable.
Principal character of the present utility model is in fire hydrant key 8, adopt spherical valve core 7 as valve blocking piece with the linked manner being with screw mandrel spanner 1, nut 2, tappet 4, spherical valve core 7 to open and close fire hydrant.
