Description
Technical field
The present invention supplies water hydraulic test, particularly relates to a kind of relief valve unit supplied water in hydraulic system.
Background technology
Along with the quickening Economization on land of urbanization process, floor is gradually increased, and this most just brings inconvenience to urban water supply,
This secondary water-supply being accomplished by using feed pump group, but feed pump group is being opened and is being stopped, along with the opening and closing of valve,
Will produce water hammer in tap water, water hammer is likely larger than several times of pressure of supply water, Shi Jibei, even tens times, so
The consequence that this phenomenon causes can be very serious, and the decompressor therefore used in pipeline is the most necessary；Decompressor is not only
There is effect of easing stress, and have pressure stabilization function.At present, the decompressor of most of tap waters, joining of its internal structure and auxiliary
Conjunction can reduce hydraulic pressure and prevent water hammer to the parts damages such as water pipe (principle of air relief valve just repeats no more).Air relief valve is pneumatic
One indispensable accessory of regulation valve, Main Function is by the pressure of source of the gas and to be stabilized to a definite value, in order to regulation valve energy
Enough obtain stable source of the gas power for regulating control.And the air relief valve connected on existing pipeline, such as diaphragm pressure reduction valve, its
Internal structure is complicated, and volume is relatively big, is not suitable for installing on the pipeline of floor, and this air relief valve is due to volume too greatly,
The quantity arranged on floor is the most limited, if but floor is too high, and the pressure that need to export is relatively big, if not having sufficient amount of decompression
Equipment, however it remains potential safety hazard.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, volume little, the air relief valve in the water supply hydraulic system that security performance is high
Device.
To achieve these goals, the present invention provides following technical scheme: the relief valve unit in water supply hydraulic system, including subtracting
Press the valve body, described air relief valve body be respectively arranged at two ends with inlet channel and outlet conduit, described air relief valve this most internal be provided with in
Cavity body, water storehouse and passage, water storehouse connects with outlet conduit, and the top of described air relief valve body is provided with and extends through internal cavity
The handle of body, is vertically arranged with helical spring in described inner cavity body, one end of described helical spring connects handle, helical spring
The other end connect and have diaphragm, the bottom of described diaphragm connects the mast being vertically arranged, and mast connects flexible clamp, described
Elastic clamp is provided with rubber slab, and the bottom of elastic clamp connects the extension spring being fixed on internal cavity body wall, and inlet channel is through subtracting
Channel connection in press the valve body has jet pipe, described jet pipe to connect with water storehouse, and described air relief valve is the most internal is additionally provided with connection source of the gas
Nozzle of air supply, described nozzle of air supply is located at the surface of rubber slab.
The principle of this programme is such that the water under high pressure of hypertonia inlet channel along air relief valve body and enters, and by spray
Pipe enters in the intrinsic water storehouse of air relief valve, and the pressure in water storehouse raises so that diaphragm overcomes the resistance of helical spring upwards
Bending, has, owing to the bottom of diaphragm connects, the mast being vertically arranged, and mast connects flexible clamp, thus is bent upwards at diaphragm
During, drive mast to move up, elastic clamp moves up therewith, and elastic clamp is provided with and is positioned at nozzle of air supply and just goes up
The rubber slab of side, therefore elastic clamp overcomes the resistance of extension spring, drives rubber slab to move upward, is covered by nozzle of air supply, reduces
Continuing with of its pressure, thus reduce the pressure carrying water in pipeline, when carrying the hypotony of water, diaphragm is at spiral bullet
It is bent downwardly under the effect of spring, utilizes the rubber slab on elastic clamp to make nozzle of air supply somewhat open, thus by the pressure in water storehouse
Power brings up to the value needed, and then discharges from outlet conduit, the handle capable of being adjustable screw spring precompressed value to diaphragm.
It is an advantage of the current invention that: the relief valve unit in this water supply hydraulic system, can be according to the height of floor, at different floors
On-demand use, volume is little, simple in construction, and security performance is reliable, it is adaptable to wideling popularize of hydraulic pressure water system.
Preferably, described diaphragm and the elastic equal horizontal card of clamp are connected on internal cavity body wall, installation, convenient disassembly, the most beneficially film
Sheet and elastic clamp compressive deformation, and produce the displacement on vertical direction.
Preferably, the intrinsic passage of described air relief valve is serpentine so that when aqueous medium flows in the inner chamber of air relief valve, energy
Concentrate the compressive deformation producing pressure, beneficially diaphragm.
Preferably, the shape of described rubber slab and the mating shapes of nozzle of air supply, beneficially rubber slab can cover air inlet spray completely
Mouth, reduces the pressure input of source of the gas, reduces the hydraulic pressure in conveying water.
Accompanying drawing explanation
Fig. 1 is that the present invention supplies water the structural representation of the relief valve unit embodiment in hydraulic system.
Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
