Abstract
The utility model belongs to the water supply and bailing field, in particular to a pneumatically water-supply equipment for the high-rise buildings. The former pneumatically water-supply equipment have the problems of wasting materials, occupying large areas and inconvenient maintenance in varying degrees. A back-pressure valve is equipped on the water absorption tube of the radial diffuser, and the sealable tank connects with a discharge pipe and a water supply pipe is connected with the sealable tank in parallel, and thus the utility model realizes the air make-up and air exhaust of the pneumatic water supply equipment, and overcomes the deficits of the former devices.
Description
The utility model belongs to the water supply and drainage field, particularly about the pneumatic installation water supply of highrise building.
The pneumatic installation water supply that replaces water tower, high level cistern in recent years is used widely.But, air supply in the pneumatic installation water supply hermetically sealed can, because being pulled away, seepage and being dissolved in the water reduces gradually, the water pump start-stop is gradually frequent, for guaranteeing that the air capacity in the hermetically sealed can remain in the scope of normal need, need tonifying Qi, continuously automatic tonifying Qi is cushion sometimes, also wants exhaust.If tonifying Qi, exhaust science are proper, will reduce investment outlay, energy conservation, enlarge the scope of application, the tonifying Qi in past has following four kinds: one, be to use the air compressor tonifying Qi, and the 2nd, utilize the air tonifying Qi of accumulating in the pumping line, the 3rd, utilize water sprayer tonifying Qi, the 4th, the emptying tonifying Qi, problems such as there is waste material in various degree in above-mentioned four kinds of tonifying Qi equipment, and consumes energy is big.
The purpose of this utility model is the deficiency at prior art, and a kind of improvement check valve location is provided and connects a stack at hermetically sealed can in parallel with water-supply-pipe, thereby makes pneumatic installation water supply more economical, more suitable.
Key of the present utility model is that flap valve is installed on the water pump suction pipe, realize automatic tonifying Qi, hermetically sealed can connects a Pai Qi Guan And and Shu Shui Guan And connection, when water pump operation, air can enter hermetically sealed can by flap valve, enters when the jar internal pressure is low in the pipe with the water system parallel connection, in jar once more behind the make up water, inner air tube is gone into water system by hydraulic pressure, discharges from the user.
The utility model is than existing pneumatic installation water supply, has advantages such as the raw material of saving, floor space are little, easy to maintenance.
The utility model implements to see accompanying drawing 1, wherein: 1 be tank (well), 2 for bottom valve, 3 flap valve, 4 water pumps, 5 for hermetically sealed can, 6 be waterline, 7 Wei And townhouse tracheae.
Accompanying drawings the utility model, the water pump that equipment adopts is an one step single sucking cantilever centrifugal water pump.After being full of water in the water pump, start motor, the rotation of driven by motor water pump vane, making the water generates energy with the inertia of the unit volume fluid of water pump vane rotation (mainly is the pressure energy, kinetic energy is also arranged), make water flowing to the water outlet tube side, and in suction water pipe and water pump, form vacuum, acting on atmospheric pressure on tank (well) free surface makes water back down the individual event valve of suction water pipe and enters in water pipe and the water pump, after, water enters hermetically sealed can by tank (well) through suction water pipe, pump housing pressure pipe with just keeping.
Flap valve on the water pump suction pipe is installed on the tubule vertical with suction water pipe, plug valve of middle series connection.Before the suction water pipe bottom valve is not opened, if the suction water pipe resistance is ignored, then the negative pressure in the tubule also promptly acts on the negative pressure on the flap valve valve and the negative pressure that acts on the bottom valve equates (when suction bottom valve valve is backed down, flap valve valve on the tubule can not be backed down by external atmospheric pressure, this is by the deadweight of flap valve valve decision, also can realize with the spring that compresses valve).Water pump begins after the suction, the flow velocity of water increases gradually in the suction water pipe, because the current in the suction water pipe are vertically broken through the tubule mouth, vacuum in the short tube further increases, water velocity in the suction water pipe is big more, and the vacuum in the short tube is big more, that is the negative pressure that acts on the flap valve short tube is big more, end the valve of valve admittedly to big strength can be backed down, air is inhaled in the pump.
So the impeller rotation makes the resulting energy of air can not flow into pressure pipe away from water pump far away.Have only a spot of small steam bubble to stay in the water pump, to the vacuum in the suction water pipe pulsating pump is reduced, the flow velocity of suction water pipe descends, the negative pressure of vertical short tube reduces, the flap valve valve is closed, staying air in the pump is taken away by the water of the pump housing and to be entered hermetically sealed can, vacuum in suction water pipe and the water pump strengthens thereupon, the switch of flap valve valve is with continuous repeat switch, if vertically short tube suitable through selecting, control air inflow (also available valve reconcile) can make flap valve valve cycle stretch-out, even reaches valve length and open.At this moment, the air capacity that enters pump equals the air capacity that water is taken away from pump.
Obviously, when this equipment was installed in well depth and by chance is the suction journey of water pump, then tonifying Qi will be interrupted and carries out.When having only well depth to inhale journey less than the permission of water pump, continuously tonifying Qi.
Claims (1)
