Description

Technical Field

[0001] The utility model mainly relates to the technical field of control valve armature assembly, in particular to a control valve assembly tool. Background Art

[0002] The control valve is composed of two main assemblies: the valve body assembly and the actuator assembly (or actuator system), which are divided into four major series: single-seat series control valves, double-seat series control valves, sleeve series control valves and self-operated series control valves. Different types of control valves are suitable for different occasions.

[0003] The function of the armature in the control valve is to energize the rotor and control the direction of rotation of the motor. It can also serve as the electrode of the motor. In the process of realizing the mutual conversion of mechanical energy and electrical energy, the armature in the control valve plays a key and vital role. The armature mainly consists of a needle head, a needle body, plastic parts, a spring and other parts. During the assembly of the plastic parts and the needle body, three aspects need to be paid attention to. If the force is small, the plastic parts and the needle body will be separated due to loose connection, causing the control valve to malfunction and unable to be used normally. If the force is large, when the needle body is inserted into the plastic part, it is easy to cause the plastic part to crack and be damaged, increasing the unqualified rate and cost. Moreover, if the needle body and the plastic part are not docked on the same axis, it is easy to cause the needle body to bend and the plastic part to be damaged due to uneven force. Therefore, the assembly is difficult, which greatly reduces the assembly efficiency. Utility Model Content
