Description
Technical field
The utility model relates to a kind of fire prevention field, relates in particular to a kind of fire hydrant.
Background technology
Fire hydrant is arranged on the water facilities on the building outside fire water-supply pipe network; The main fire fighting truck that supplies is implemented fire extinguishing from municipal water supply pipe network or the water intaking of outdoor fire fighting water supply network; Also can directly connect water band, hydraulic giant water outlet fire extinguishing, so hydrant system also is one of important fire fighting device that fights a fire.When changing appearred in the hydraulic pressure at the water source that supplies fire hydrant, different hydraulic pressure was to the effect of water outlet.Especially at the indoor fire hydrant of skyscraper, because for satisfying high-rise needs, the pressure of its water supply can be very big, when being applied in underground or during at low layer, the pressure at its water source can be very big, the water outlet superpressure of fire hydrant can occur, influences the normal use of fire hydrant.Therefore be necessary to invent its device with voltage stabilizing that reduces pressure automatically of fire hydrant, to guarantee the operate as normal of fire hydrant.
The utility model content
The utility model is the shortcoming to above-mentioned existence, existing fire hydrant is improved, with the function of the voltage stabilizing that realizes reducing pressure.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of fire hydrant of the voltage stabilizing of reducing pressure comprises valve body and handwheel, and valve body is provided with exhalant canal; It is characterized in that exhalant canal is provided with into the water ring and goes out water ring, water inlet ring and go out to be respectively equipped with water inlet and delivery port on the water ring, the water inlet ring around the water inlet is provided with aperture; Go out the end that water ring is fixed on exhalant canal; The water inlet ring is located at the front end of exhalant canal, and the water inlet ring can move at exhalant canal, and water inlet ring and water outlet interannular are provided with balancing spring.The water inlet ring of the utility model, go out water ring peace weighing apparatus spring and on exhalant canal, formed decompression, voltage stabilizing mechanism.The water inlet lopps is like piston, axial move left and right under the water flow pressure effect, and balancing spring is used for the balance current to the right thrust of water inlet hoop, makes into water ring and water outlet ring formation certain spacing, when handwheel is opened valve, the pressure flow entering mechanism of decompressor.The hoop that promotes to intake goes out the water ring direction and moves; Balancing spring is compressed the bourn acting force that the Spring balanced water inlet hoop of generation moves to right, and form certain spacing in water inlet ring right side with the water outlet interannular this moment, and this spacing is through the last water stream channel of aperture of water inlet ring; Whether this spacing flows with import water flow pressure size and water changes; At press water is under the mobility status, the hydraulic pressure height then intake the ring amount of moving to right big, spacing is then little; This spacing is the passage of current, and the expenditure and pressure effect to the import current has been played in its variation.
As preferably, be provided with the ladder bulge loop between aperture on the water inlet ring end face and inlet opening, the bulge loop correspondence is going out the water ring end, and bulge loop can improve the decompression of the current of aperture and pressure stabilization function.
As preferably, go out the water ring end face and be provided with ladder dome ring, ladder dome ring correspondence is at water inlet ring end, and the dome ring also is decompression and the pressure stabilization function that improves the current of aperture.
Aperture on the above-mentioned water inlet ring is 4-6, is evenly distributed on the water inlet water inlet ring on every side.
The beneficial effect of the utility model is: the utility model water inlet encircles, goes out water ring peace weighing apparatus spring and on exhalant canal, formed decompression, voltage stabilizing mechanism; Owing to increased the decompression voltage stabilizing function; Realized the hydraulic pressure at the different water sources of automatic adaptation; Stablize water outlet hydraulic pressure within the specific limits, guaranteed the security reliability of fire-fighting fire extinguishing, and reduced the loss of water resource.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the water inlet ring structure sketch map of the utility model embodiment.
Among the figure: 1, handwheel 2, valve body 3, passage 4, water inlet encircle 5, go out water ring 6, balancing spring 41, water inlet 42, bulge loop 43, aperture 51, delivery port 52, dome ring.
The specific embodiment
In Fig. 1, Fig. 2, a kind of fire hydrant of the voltage stabilizing of reducing pressure comprises valve body 2 and handwheel 1; Valve body 2 is provided with exhalant canal 3, and exhalant canal 3 is provided with into water ring 4 and goes out water ring 5, water inlet ring 4 with go out to be respectively equipped with on the water ring 5 water inlet 41 and delivery port 51; Evenly be provided with five apertures 43 on the water inlet ring around the water inlet 41, aperture 43 and 41 of inlet openings on water inlet ring 4 end faces are provided with ladder bulge loop 42, go out water ring 5 end faces and are provided with ladder dome ring 52; Go out the end that water ring 5 is fixed on exhalant canal 3; Water inlet ring 4 is located at the front end of exhalant canal 3, and water inlet ring 4 can move at exhalant canal 3, water inlet ring 4 and go out 5 of water rings and be provided with balancing spring 6.
The water inlet ring 4 of the utility model, go out water ring 5 and balancing spring 6 has been formed decompression, voltage stabilizing mechanism on exhalant canal 3.Water inlet ring 4 similar pistons, the axial move left and right water flow pressure effect under, balancing spring 6 is used for the balance current to the right thrust of water inlet hoop, and make into water ring 4 and go out water ring 5 formation certain spacing, when handwheel 1 is opened valve, the pressure flow entering mechanism of decompressor.Promoting water inlet ring 4 moves to going out water ring 5 directions; Balancing spring 6 is compressed the bourn acting force that the Spring balanced water inlet ring 4 of generation moves right, and form certain spacing in water inlet ring 4 right sides with going out 5 of water rings this moment, and this spacing is to encircle the water stream channel of the aperture 43 on 4 through water inlet; Whether this spacing flows with water inlet 41 flowing pressures size and water changes; At press water is under the mobility status, the hydraulic pressure height then intake the ring 4 amounts of moving to right big, spacing is then little; This spacing is the passage of current, and the expenditure and pressure effect to the import current has been played in its variation.
