Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Fig. 1～3, a kind of vacuum breakdown device of vacuum be used to preventing that siphon from occuring comprises upper connecting tube 1, middle adapter 2, lower linking tube 3 and rubber sphere 4.The top and bottom of middle adapter 2 are provided with internal thread, and the lower end of the top and bottom of lower linking tube 3 and upper connecting tube 1 is equipped with outside screw, and upper connecting tube 1, middle adapter 2 are connected with lower linking tube by the screw thread connection successively from top to bottom of coupling, form ventilator trunk.The bottom of upper connecting tube 1 is the Taper Pipe 11 that an inner tubal wall is frustum, and the upper end of lower linking tube 3 is provided with a perforated baffle 31, and rubber sphere 4 is located in middle adapter 2, and the top is blocked by Taper Pipe 11, and the lower end is blocked by perforated baffle 31, can move up and down in middle adapter 2.
The screw thread place of its connection is provided with the polytetrafluoro raw material band and is sealed, and is built in the rubber sphere that rubber sphere 4 in middle adapter 2 can adopt the materials such as butyronitrile on sale on market or second the third glue, and its density is respectively 1.53g/cm
3, and 0.86g/cm
3The internal diameter of three adapters is generally between 8～20cm, the internal diameter of middle adapter 2 is greater than the internal diameter of upper connecting tube 1 and lower linking tube 1, upper connecting tube 1, lower linking tube 3 internal diameters can equate, be about 4/5～9/10 times of middle adapter 2 internal diameters, length is preferably 1～1.5 times of internal diameter separately, and rubber sphere 4 diameters are preferably 2/3～4/5 of middle adapter 2.On perforated baffle 31, pre-opened hole is preferably 1/5～1/3 of lower linking tube 3 internal diameters, and perforate should be got 3～6, gets 4 in the present embodiment, evenly is arranged on perforated baffle 31, and concrete structure as shown in Figure 4.
The principle that the shape of Taper Pipe 11 and size are determined is when blower fan works, rubber sphere 4 can be closely tangent with Taper Pipe 11, make device be in the state of sealing, when blower fan quits work, the minimum diameter size on its Taper Pipe 11 tops needs to make extraneous atmosphere to enter rapidly in pipeline, destroy vacuum state, Taper Pipe top minimum diameter is preferably 1/2 times of left and right of upper connecting tube internal diameter.
During the normal aeration working order of blower fan, the structure of device as shown in Figure 2: gas in aerated conduit flows into vacuum breakdown device of vacuum through the interface of lower linking tube 3 lower ends.In middle adapter 2, rubber sphere 4 stressing conditions are: rubber sphere 4 is subject to the pressure of lower air, pressure is greater than himself downward gravity, usually the gaseous tension in aerated conduit is sufficiently more than and overcomes rubber sphere 4 gravity, general blast can satisfy job requirement in the 200Pa left and right, and more than normal wind is pressed in 30000Pa.Rubber sphere 4 to floating up in Taper Pipe 11, is agreed with Taper Pipe 11 in middle adapter 2 under the force action that makes progress closely, allows whole aerating system be in the state of sealing.
During the fan parking state, the structure of this device as shown in Figure 3: cause that the gaseous tension in aerated conduit reduces fast, rubber sphere 4 loses lower wall pressure, due to its action of gravity.Fall on perforated baffle 31 in middle adapter 1, at this moment, extraneous atmosphere flows in middle adapter 2 by the upper end of upper connecting tube 1, then enters into aerated conduit through the pre-opened hole on perforated baffle 31, destroy issuable negative-pressure siphon effect, avoid sewage because of the generation of siphon backwater phenomenon.
When blower fan was opened again, rubber sphere 4 during floating is closely agreed with Taper Pipe 11 again, entered into the normal aeration working order of blower fan due to the effect of the air pressure that increases in aerated conduit.The present invention can prevent that blower fan sewage when shutdown or instantaneous shutdown from entering aerated conduit because of the siphon backwater, avoids pipeline, equipment cause corrosion or destroy the even loss that causes of the indoor water entering accident of machine room because of water inlet.
