DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below.

[0013] like Figure 1 As shown, a blowing air control valve for a high borosilicate glass blowing molding production line comprises a valve seat 1, a sliding block 2 and a cylinder 3. A blowing air inlet 4 is provided on one side of the valve seat 1, and a blowing air outlet 5 is provided on the other side; the blowing air inlet 4 and the blowing air outlet 5 are connected via a "J"-shaped air passage 6; the sliding block 2 is arranged in the middle of the "J"-shaped air passage 6, and the sliding block 2 is slidably connected to the body of the valve seat 1; the cylinder 3 is arranged below the sliding block 2, and the output end of the cylinder 3 is connected to the bottom of the sliding block 2; the bottom of the valve seat 1 is connected to a mounting seat 7 on both sides via a connecting rod; the cylinder 3 is connected to the mounting seat 7.

[0014] The vertical air channels on both sides of the "J"-shaped air channel 6 are provided with a first air channel 8 and a second air channel 9, and a notch 10 is provided on the valve seat 1 body at the upper end of the "J"-shaped air channel 6, and the notch 10 is used to accommodate the end of the sliding block 2; a third air channel 11 and a fourth air channel 12 are provided in the sliding block 2 from top to bottom; the first air channel 8 is located above the second air channel 9, and the first air channel 8 and the second air channel 9 are both arranged horizontally; the first air channel 8 and the third air channel 11 have the same diameter, the second air channel 9 and the fourth air channel 12 have the same diameter, and the diameter of the first air channel 8 is greater than the diameter of the second air channel 9.

[0015] A first sealing ring 13 is connected to the inner wall of the notch 10; a second sealing ring 14, a third sealing ring 15 and a fourth sealing ring 16 are sequentially sleeved on the outer side of the sliding block 2, the second sealing ring 14 is located above the first air duct 8, the third sealing ring 15 is located between the first air duct 8 and the second air duct 9, and the fourth sealing ring 16 is located below the second air duct 9.

[0016] Working principle: when the control valve is working, when the glassware is initially formed, the blowing air is supplied from the "J"-shaped air channel 6 to the blowing air outlet 5. When the glassware is formed, the cylinder 3 works and pushes the sliding block 2 to slide upward. At this time, the first air channel 8 is connected with the third air channel 11, and the blowing air is supplied through the "J"-shaped air channel 6 and the first air channel 8 at the same time to increase the air supply and make the glassware take shape quickly. When the glassware is under pressure, the cylinder 3 continues to work and pushes the sliding block 2 to slide upward. The end of the sliding block 2 is inserted into the notch 10, closing the "J"-shaped air channel 6 and the first air channel 8. At this time, the second air channel 9 is connected with the fourth air channel 12 to continue to supply air to the equipment to maintain pressure.
