Abstract
The utility model discloses a rapid air evacuation valve for a pneumatic control system. The rapid air evacuation valve consists of a cylinder body and a piston, wherein the cylinder body is provided with a piston cylinder; the upper end of the cylinder body is provided with an air inlet; the bottom end of the cylinder body is provided with an air outlet; the lower segment of the cylinder body is provided with an air vent; the piston is located inside the piston cylinder of the cylinder body; the piston is sealed from the piston cylinder by two sealing rings; the diameter of the lower segment of the piston is smaller than that of the piston; the cylinder body and the piston are installed at the air discharge hole of the pneumatic control system; when a main system has pressure, the piston is pressed by the pressure to move downwards, the air outlet is sealed, and compressed air of a sub-system can not be evacuated of the air outlet through the air vent and the piston cylinder; and when the pressure of a main system is reduced or the main system has no pressure, the piston is pushed to move upwards by the compressed air of the sub-system and is free from sealing the air outlet, an air passage is opened completely, and the compressed air of the sub-system is rapidly evacuated out of the air outlet through the air vent and the piston cylinder. The rapid air evacuation valve controlled by the pressure of the main system is capable of rapidly evacuating the gas of the main system.
Description
Technical field
The utility model relates to the rapid-release valve that a kind of atmospheric control is used.
Background technique
In atmospheric control, for rapid exhaust, rapid-release valve need to be arranged.
Summary of the invention
The purpose of this utility model provides the rapid-release valve that a kind of atmospheric control is used.
The utility model is to be made of cylinder body and piston, cylinder body has piston cylinder, the upper end of cylinder body is suction port, the bottom of cylinder body has the air outlet, the hypomere of cylinder body offers ventilating hole, and piston is arranged in the piston cylinder of cylinder body, between piston and the piston cylinder with two road seal ring seals, the diameter of the hypomere of piston is less than the diameter of piston, and cylinder body is installed on the vent hole place of atmospheric control together with piston.
Principle and the process of the utility model Rapid degassing are:
When main system had air pressure, air pressure was to pressing down piston, and piston moves down, and closes the air outlet, and the pressurized air of subtense angle can not be discharged from the air outlet through ventilating hole and piston cylinder;
When main system air pressure reduces or during without air pressure, the pressurized air ejector ram of subtense angle is up, piston breaks away from the sealing to the air outlet, and air flue is opened fully, and the pressurized air of subtense angle is promptly discharged from the air outlet through ventilating hole and piston cylinder.
The beneficial effects of the utility model are: the control of the utility model acceptor system air pressure, can fast the gas of subtense angle be discharged, and satisfy the needs of atmospheric control control.
Description of drawings
Fig. 1 is the utility model embodiment's sectional view.
Embodiment
See also shown in Figure 1, be embodiment of the present utility model, it is to be made of cylinder body 1 and piston 2, and cylinder body 1 has piston cylinder 11, and the upper end of cylinder body 1 is suction port 12, the bottom of cylinder body 1 has air outlet 13, the hypomere of cylinder body 1 offers ventilating hole 14, and piston 2 is arranged in the piston cylinder 11 of cylinder body 1, seals with two road seal rings 3 between piston 2 and the piston cylinder 11, the diameter of the hypomere 21 of piston 2 is less than the diameter of piston 2, and cylinder body 1 is installed on the vent hole place of atmospheric control together with piston 2.
Principle and the process of present embodiment Rapid degassing are:
When main system A had air pressure, air pressure was to pressing down piston 2, and piston 2 moves down, and closes air outlet 13, and the pressurized air of subtense angle B can not pass through ventilating hole 14 and piston cylinder 11 13 discharges from the air outlet;
When main system A air pressure reduces or during without air pressure, the pressurized air ejector ram 2 of subtense angle B is up, the sealing that piston 2 breaks away from air outlet 13, air flue is opened fully, and the pressurized air of subtense angle B promptly 13 is discharged from the air outlet through ventilating hole 14 and piston cylinder 11.
