Description

Electric regulating valve

Technical Field

The utility model relates to a pot-type warehousing and transportation equipment valve field. In particular to a special valve for tank containers, road tank trucks and railway tank trucks and static storage tanks. In particular to an electric regulating valve.

Background

In the conventional lifting type bottom valve, the lifting guide mechanism 3 of the valve core 2 is a circular guide structure surrounding the valve core 2, and three points of the circular structure are all connected with the valve body 1. When the bottom valve is opened, the mandril overcomes the pressure of the spring 6 to jack up the valve core 2 below the valve core 2, the valve core 2 vertically rises under the constraint of the circular guide mechanism 3, and the valve is opened; when the bottom valve is closed, the jacking force of the jacking rod is removed, the valve core 2 falls back under the pressure of the spring 6, and then the valve is closed. Due to the limitation of structural design, the force generated when the valve mandril jacks up the valve core is not a completely vertical axial force, and a certain radial force (transverse force) is generated. Friction inevitably occurs between the spool 2 and the guide mechanism 3 during the lifting and dropping of the spool 2. In addition, in the production process, the shape, roughness, and appropriate clearance of the contact surface between the valve element 2 and the guide structure 3 are difficult to be in an ideal state for many reasons such as the production process, and the production cost. Therefore, in the use process of the bottom valve product with the structure, the situations of scraping, chip falling, blocking, untight closing in the falling process and the like are inevitably generated by the valve core and the guide structure.

Besides, the existing three-point fixed connection and circular guide structure bottom valve has some places to be improved and enhanced:

when the valve is opened, not only the vertical spring pressure and the pressure of a medium in a tank need to be overcome, but also a certain radial force (transverse force) needs to be overcome, so that the opening torque is increased, the operation is relatively laborious, and a shaft and a handle for driving the ejector rod are easy to damage;

secondly, the original spring gland is connected with the guide structure in a hook mode, so that the spring gland is easy to fall off and lose efficacy;

third, because when the valve was opened to original design, the case only promoted perpendicularly in circular guiding mechanism, and the height that promotes is limited moreover, and the jar medium can only pass through and flow out in the side of case lower part, and the block of three structures of being connected with the valve body has influenced the speed that the medium leaked (especially viscous and granule medium) more double image, and this has just led to the fact the efficiency of unloading not ideal.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electric control valve. The friction and the blocking between the valve core and the guide structure are reduced to the maximum extent, and the untight closing is avoided. The opening torque is reduced.
