Abstract
The utility model discloses a low pressure casting exhaust valve, which is one of the essential elements in a low pressure casting machine, and can control the low pressure casting machine in a relatively constant pressure, but existing low pressure casting exhaust valves can not work in high temperature environment, and can not be excellently sealed by effectively controlling sealing parts when needing to close. Because of adopting a high temperature resistance air cylinder, the low pressure casting exhaust valve can work in high temperature environment, and a piston of the high temperature resistance air cylinder forwardly stretches when the air pressure is not enough, thereby enabling a sealing steel ball to go forward. Because the diameter of the sealing steel ball is bigger than a connecting cavity, a main connecting cavity can be completely sealed by the sealing steel ball, thereby guaranteeing sealing of the low pressure casting exhaust valve.
Description
Technical field
The utility model belongs to machining equipment field, is specially a kind of air injection machine air bleeding valve.
Background technology
One of requisite element in the air injection machine of low pressure casting air bleeding valve, it can control air injection machine at a relatively constant air pressure, but existing low pressure casting air bleeding valve can not be worked under hot environment, and when it can not need to seal, effectively control seal, can seal preferably.
Summary of the invention
In order to address the above problem, the utility model proposes a kind of air injection machine air bleeding valve, adopt after the utility model, can under hot environment, carry out work, and guarantee sealing.
A kind of air injection machine air bleeding valve, its technical scheme is such: it comprises fumer, in described fumer, have outlet chamber, it is characterized in that: it also comprises high temperature-resistant cylinder, sealing steel ball, and described high temperature-resistant cylinder is connected and fixed on described fumer by connecting rod, and the front end of described high temperature-resistant cylinder is extended with piston, the front end of described piston is connected with sealing platform, described sealing platform stretches in described fumer, and stretches into described outlet chamber, on described sealing platform, is fixed with sealing steel ball; Described outlet chamber is divided into inlet chamber and discharge chamber, described inlet chamber is at the rear side of described fumer, described discharge chamber is in the front side of described fumer, and described inlet chamber is connected by connection chamber with described discharge chamber, and the diameter of described connection chamber is less than the diameter of described sealing steel ball.
It is further characterized in that: described inlet chamber and described discharge chamber are all parallel to the axis of described fumer.
Adopt after the utility model, owing to having adopted high temperature-resistant cylinder, so the utility model can carry out work under hot environment, when air pressure is inadequate, the piston forward of high temperature-resistant cylinder is stretched, thereby makes to seal steel ball forward, because the diameter of sealing steel ball is larger than connection chamber, so sealing steel ball can seal main connection chamber completely, thereby has guaranteed its sealing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
See Fig. 1, a kind of air injection machine air bleeding valve, it comprises fumer 1, high temperature-resistant cylinder 2, sealing steel ball 3, in fumer, have outlet chamber 4, high temperature-resistant cylinder 2 is connected and fixed on fumer 1 by connecting rod 5, and the front end of high temperature-resistant cylinder 2 is extended with piston 6, the front end of piston 6 is connected with sealing platform 7, sealing platform 7 stretches in fumer 1, and stretches into outlet chamber 4, is fixed with sealing steel ball 3 on sealing platform; Outlet chamber 4 is divided into inlet chamber 8 and discharge chamber 9, inlet chamber 8 is at the rear side of fumer 1, discharge chamber 9 is in the front side of fumer 1, inlet chamber 8 is connected by connection chamber 10 with discharge chamber 9, the diameter of connection chamber 10 is less than the diameter of sealing steel ball 3, and inlet chamber 8 and discharge chamber 9 are all parallel to the axis 11 of fumer 1.
