Description

Durable pneumatic adjustable pouring valve in vacuum tank

Technical Field

The utility model belongs to the technical field of the vacuum tank, especially, relate to a pneumatic adjustable pouring valve of durable type in vacuum tank.

Background

The pouring valve is used for vacuum pouring of resin, namely, the treated resin sizing material is poured into a mold through the pouring valve by utilizing gravity or a delivery pump in a vacuum state.

However, the stroke of the existing pouring valve is not adjustable, and the driving is mostly driven by a standard air cylinder. On one hand, the adjustable requirements of the pouring process on the pouring pressure and the pouring speed are difficult to meet; on the other hand, due to the high-temperature environment in the pouring box and the existence of resin volatile matters, the service life of the cylinder is greatly reduced, and the maintenance frequency and the cost are increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mechanism of pouring chamber door around connecting under new-type vacuum.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a pneumatic adjustable pouring valve of durable type in vacuum tank, including adjusting part, valve body, piston, needle and disk seat, sliding connection has the piston in the valve body, the piston downside is equipped with the needle, the valve body is worn to locate by the needle to with valve body sliding connection, the feed inlet has been seted up to the valve body lower part, the inboard lower part of feed inlet is equipped with the disk seat, the piston upper end is connected with adjusting part, adjusting part is located the valve body outside, valve body upper portion one side is equipped with the business turn over gas port, valve body lower part one side is equipped with the business turn over gas port.

Preferably, a piston sealing ring is arranged on the piston and is matched with the inner side of the valve body in advance.

Preferably, a valve needle sealing ring is arranged between the valve body and the valve needle, and the valve needle sealing ring is fixedly connected with the valve body and is in sliding connection with the valve needle.

The utility model discloses following beneficial effect has:

the utility model, through the integrated design of the pneumatic control and the material flow channel, avoids the requirement for the standard cylinder, and makes the whole structure more compact; the manual adjustment and rotation adjusting part can control the gap between the valve needle and the valve seat, thereby controlling the material discharging speed and pressure.
