Description
Technical field
This utility model relates to a kind of diaphragm air pressure tank, belongs to air pressure tank field.
Background technology
Diaphragm air pressure tank is also known as pipe network vacuum tank.Its use occasion is by domestic water system, fire supply system etc..Mainly
Use function is: (1) eliminates water hammer: when pipe network forms water hammer, in tank, gas compression absorbs portion of energy, it is to avoid water hammer
The loss brought.(2) automatic water-supply: the pressure that may utilize air pressure tank compressed air when water pump is out of service will be stored in tank
Water send into water supply network, to extend water pump dwell time, it is to avoid water pump frequent start-stop.(3) regime flow: set in frequency conversion feedwater
In Bei, owing to the transmission of pressure signal has individual time course, air pressure tank can make up the fluctuation of this section of time pressure of supply water.(4) replace
For expansion tank: in boiler and air conditioning system, ductwork pressure may change along with the change of water temperature, when ductwork pressure raises
Time, air pressure tank can absorb the thermal expansion water yield.
At present, mostly diaphragm air pressure tank is to use and the most all leaves opening, is respectively mounted flange, adapter and blind flange, barrier film
Balloon ends connects with upper and lower opening respectively, it addition, top is additionally provided with pressure gauge connection, tank body is additionally provided with inflation inlet, under open
Mouth is intake-outlet.From the point of view of use experience, the opening of tank deck, inflation inlet and pressure gauge connection are required to strict seal, and
And the flange of upper shed, adapter, blind flange and bolt occupy certain space so that diaphragm air pressure tank entirety is the compactest.?
After originally the flange of tank deck, adapter, blind flange and bolt are all cancelled, both reduced original equipment total height, in turn ensure that former
Come total measurement (volume) so that overall structure is the compactest attractive in appearance, in the middle of also reduce more than 15% cost of transportation, for terminal use
Brief spatial area, significantly reduces production cost, has saved resource to country.Inflation inlet and pressure gauge connection are closed two is
One, inflation inlet is arranged in the tank body first half, has both decreased a leakage point, and convenient pressure of observing changes again, when also preventing from using
Capsule sagging blocking inflation inlet.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of diaphragm air pressure tank, it solves barrier film air pressure
Leaving an opening more on tank, easily produce air leakage point, upper shed structure is the compactest, transport inconvenience, product cost and making
The problem increased with cost.
Technical problem to be solved in the utility model takes techniques below scheme to realize:
A kind of diaphragm air pressure tank, it includes that tank body, described tank base are provided with intake-outlet and bearing, and top is provided with hanger
With upper folder film mouth, inside is provided with barrier film air bag, and the upper film mouth of described barrier film air bag is provided with screw thread, and threaded upper film mouth passes through spiral shell
Bolt seals and is fixed at folder film mouth, and the lower film mouth of barrier film air bag is connected with intake-outlet, and seals fixing, on described tank body
Half portion is provided with inflation pressure tap, seals and be fixed with inflation pressure measurement connector at described inflation pressure tap.
As preferred embodiment, described inflation pressure measurement connector is provided with connector, inflation inlet and pressure tap, connector and tank body
On inflation pressure tap connection, inflation pressure measurement connector inside, inflation inlet, pressure tap connect with connector respectively.
As preferred embodiment, described intake-outlet passes through flange or the water pipe that has been screwed.
The beneficial effects of the utility model are: simplify tank body top structure, by the flange of upper folder film mouth, the fixing side of blind flange
Formula replaces with bolt and fixes, and structure is compacter, convenient transportation, reduces product cost and use cost；By inflation inlet and pressure measurement
Mouth unites two into one, and decreases an air leakage point, strengthens reliability；Inflation inlet is located at the tank body first half, prevents barrier film air-pocket obstruction
Inflation inlet.
