Description
Technical field
Nozzle mechanism device of the present invention relates to a kind of vacuumizing and uses workpiece, and particularly a kind of is the nozzle mechanism device with oblique T shape of vacuumizing of foundation with the bernoulli's equation.
Background technique
One of method that a seal space is vacuumized utilizes the threeway of T font to finish the work that seal space is vacuumized for according to bernoulli's equation now.Its working principle is that the lower end of T font threeway vertical tube and seal space are connected, left end injecting compressed air at T font threeway horizontal pipe, in the pipeline section of the horizontal pipe of threeway, form the low pressure area of high velocity air, like this because the air pressure in the seal space is higher than the air pressure at horizontal pipe place, air outwards flows in the seal space, after-fixed time, the air in the seal space is drawn out of.The structure of effect quality that vacuum is taken out and the threeway of being adopted has confidential relation.
The structure of the existing T shape threeway that seal space is vacuumized as shown in Figure 1, this T shape threeway is by constituting in the vertical tube 3 vertical screws 46 that screw on horizontal pipe 4 sidewalls.Through-hole structure in the threeway of T shape is: the pipeline section of the vertical tube 3 of T shape threeway is the identical elongated pipeline section 31 of diameter, horizontal pipe 4 45 is followed successively by one-level suction tude 41, secondary suction tude 42, one-level steam outlet pipe 43 and secondary steam outlet pipe 44 by suction port 40 to the air outlet, the diameter of the diameter of secondary steam outlet pipe 44=one-level suction tude 41〉diameter of one-level steam outlet pipe 43〉diameter of secondary suction tude 42, the elongated pipeline section 31 of the vertical tube 3 of T shape threeway communicates with the secondary inlet hole of horizontal pipe 4.
There is following shortcoming in T shape threeway as shown in Figure 1:
1. the intakeport sectional area is less, does not utilize the outflow of seal space gas;
2. the one-level inlet hole of horizontal pipe to the jointing of secondary inlet hole is a dull face, when pressurized gas enters, has influenced the speed of air-flow, thereby has influenced the pressure of air-flow;
3. since vertical tube and horizontal pipe by being threaded, poor sealing, it is not enough to pull out air quantity;
4. horizontal pipe is connected with the vertical tube right angle, and the obstructed resistance of air-flow is big.
Above shortcoming all can increase the consumption of energy consumption and increase the activity duration.
