Description
Technical field
The utility model relates to valve body technical field, specifically a kind of core shooter air bleeding valve.
Background technology
Former clamping tube type air bleeding valve in use damages and is difficult for finding, produces and just checks replacing when abnormal, cannot field maintenance, more difficult when maintenance, cause production efficiency not reach client's demand, and damage time can not be keeped in repair timely, other equipment are also affected.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, a kind of novel air bleeding valve is provided, this valve is applied on core making machine, while penetrating sand, programme-control air operated reversing valve is connected, close air bleeding valve, make to penetrate sand cover internal gas pressure and ensure 4bar, penetrate programme-control exhaust timely after sand, penetrate sand mouth after sand and leak sand in order to avoid penetrate.
For achieving the above object, design a kind of core shooter air bleeding valve, comprise valve gap, valve body, blast pipe, it is characterized in that: the two ends of valve gap are connected with valve body by bolt, in valve body, be provided with blast pipe, one end of described blast pipe is positioned at valve body, and the other end of blast pipe is positioned at the outside of valve body.
Described valve body is small top and big bottom bowl structure, and the upper portion side wall of valve body is provided with steam vent, and the lower sides of valve body is provided with chip-removal hole.
Between described valve gap and valve body, be provided with seal membrane, the upper end bonding of seal membrane is provided with circular metal plate.
The upper end of described valve gap is provided with switch control mouth.
The utility model compared with the existing technology, provides a kind of novel air bleeding valve, and this valve is applied on core making machine, while penetrating sand, programme-control air operated reversing valve is connected, and closes air bleeding valve, makes to penetrate sand cover internal gas pressure and ensures 4bar, penetrate programme-control exhaust timely after sand, penetrate sand mouth after sand and leak sand in order to avoid penetrate.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is switch control mouth, and 2 is valve gap, and 3 is seal membrane, and 4 is steam vent, and 5 is valve body, and 6 is chip-removal hole, and 7 is blast pipe, and 8 is circular metal plate.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the two ends of valve gap 2 are connected with valve body 5 by bolt, are provided with blast pipe 7 in valve body 5, and one end of described blast pipe 7 is positioned at valve body 5, and the other end of blast pipe 7 is positioned at the outside of valve body 5.
Valve body 5 is small top and big bottom bowl structure, and the upper portion side wall of valve body 5 is provided with steam vent 4, and the lower sides of valve body 5 is provided with chip-removal hole 6.
Between described valve gap 2 and valve body 5, be provided with seal membrane 3, the upper end bonding of seal membrane 3 is provided with circular metal plate 8.
The upper end of valve gap 2 is provided with switch control mouth 1.
This valve is made up of valve body 5, valve gap 2 and seal membrane 3, and the upper end of seal membrane 3 is the circular metal plates 8 that are bonded together with seal membrane 3, can play fast sealing and prevent the middle damaged operation that affects equipment of seal membrane 3; In use, directly connect the import of valve body 5 with blast pipe 7, control air valve opening and closing and can control the exhaust of core shooter and penetrate sand action.
Air bleeding valve of the present utility model is applied on core making machine, and while penetrating sand, programme-control air operated reversing valve is connected, and closes air bleeding valve, makes to penetrate sand cover internal gas pressure and ensures 4bar, penetrates programme-control exhaust timely after sand, penetrates sand mouth after sand and leaks sand in order to avoid penetrate.New-type air bleeding valve is smaller to Influence of production after damaging, and is convenient to check find fault, can on-the-spot repair and replacement part, improve greatly production efficiency installation and maintenance convenient, and use cost is low, failure rate is low.
