Description
Technical field
The present invention supplies water hydraulic equipment, particularly relates to a kind of relief valve unit supplied water in hydraulic system.
Background technique
Along with the quickening Economization on land of urbanization process, floor increases gradually, and this just brings inconvenience to town water supply undoubtedly, and this just needs the secondary water-supply using raw water service pump group, but raw water service pump group is in unlatching and stopping, along with the opening and closing of valve, all can produce water hammer in tap water, water hammer may be greater than several times of pressure of supply water, tens times, even tens times, so the consequence that this phenomenon causes can be very serious, the decompressor therefore adopted in pipeline is very necessary; Decompressor not only has effect of easing stress, and has pressure stabilization function.At present, the decompressor of most of tap water, the cooperation of its internal structure and auxiliary can reduce hydraulic pressure and prevent water hammer to the parts damages such as water pipe (principle of reduction valve just repeats no more).Reduction valve is an indispensable accessory of pneumatic control valve, and Main Function is by the pressure of source of the gas and is stabilized to a definite value, so that modulating valve can obtain stable source of the gas power for regulable control.And the reduction valve that existing pipeline connects, such as diaphragm pressure reduction valve, its internal structure is complicated, and volume is comparatively large, is not suitable for installing on the pipeline of floor, and this reduction valve is due to the too large reason of volume, the quantity that floor is arranged is often limited, if but floor is too high, and the pressure that need export is larger, if there is no the pressure regulating equipment of sufficient amount, still there is potential safety hazard.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, volume is little, the relief valve unit in the water supply hydraulic system that Safety performance is high.
To achieve these goals, the invention provides following technological scheme: the relief valve unit in water supply hydraulic system, comprise reduction valve body, the two ends of described reduction valve body are respectively equipped with intake pipe and outlet conduit, inner cavity body is provided with in described reduction valve body, water storehouse and passage, water storehouse is communicated with outlet conduit, the top of described reduction valve body is provided with the handle extending through inner cavity body, vertically helical spring is provided with in described inner cavity body, described helical spring one end connecting handle, the helical spring the other end is connected with diaphragm, the bottom of described diaphragm is connected with the mast vertically arranged, mast is connected with elasticity clamp, described elasticity clamp is provided with rubber plate, the bottom of elasticity clamp is connected with the extension spring be fixed on inner cavity body wall, intake pipe has jet pipe through the intrinsic channel connection of reduction valve, described jet pipe is communicated with water storehouse, the nozzle of air supply being communicated with source of the gas is also provided with in described reduction valve body, described nozzle of air supply is located at directly over rubber plate.
The principle of this programme is such: the high pressure water of overpressure enters along the intake pipe on reduction valve body, and enter in the intrinsic water storehouse of reduction valve by jet pipe, pressure in water storehouse raises, make diaphragm overcome helical spring resistance to be bent upwards, bottom due to diaphragm is connected with the mast vertically arranged, mast is connected with elasticity clamp, thus in the process be bent upwards at diaphragm, drive mast moves up, elasticity clamp moves up thereupon, elasticity clamp is provided with the rubber plate be positioned at directly over nozzle of air supply, therefore elasticity clamp overcomes the resistance of extension spring, drive rubber plate moves upward, nozzle of air supply is covered, reduce the continuation input of its pressure, thus in reduction pipeline, carry the pressure of water, when carrying the hypotony of water, diaphragm is bent downwardly under helical spring effect, utilize the rubber plate on elasticity clamp that nozzle of air supply is opened a little, thus the pressure in water storehouse is brought up to the value of needs, then discharge from outlet conduit, handle capable of being adjusting color screw spring is to the precompressed value of diaphragm.
The invention has the advantages that: the relief valve unit in this water supply hydraulic system, can according to the height of floor, use as required at different floor, volume is little, and structure is simple, and Safety performance is reliable, is applicable to wideling popularize of hydraulic pressure water system.
Preferably, described diaphragm and the equal horizontal card of elasticity clamp are connected on inner cavity body wall, and installation, convenient disassembly, be also beneficial to diaphragm and elasticity clamp compressive deformation, and produce the displacement on vertical direction.
Preferably, the intrinsic passage of described reduction valve is serpentine, when aqueous medium is flowed in the inner chamber of reduction valve, can concentrate and produce pressure, be beneficial to the compressive deformation of diaphragm.
Preferably, the shape of described rubber plate and the mating shapes of nozzle of air supply, be beneficial to rubber plate and can cover nozzle of air supply completely, reduces the pressure input of source of the gas, reduce the hydraulic pressure in conveying water.
