Description

Technical Field

[0001] The utility model mainly relates to the technical field of control valve armature assembly, in particular to an installation tool for a control valve elastic part. 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 rotation direction 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, a needle body, a plastic part, a spring and other parts. During the assembly of the plastic part and the spring, the staff needs to squeeze and compress the spring in advance to shorten the spring, and then put the spring into the groove in the plastic part. When putting it in, because the groove on the plastic part is small, it is often due to improper operation, causing one end of the spring to pop out of the groove, so it needs to be reinstalled, which is very time-consuming and has low work efficiency.

A push rod 22 is provided on one side of the support seat 21, and the push rod 22 passes through the through hole 142.

[0024] Through the above structure, during the assembly of the control valve armature, the spring body 4 can be in a compressed state, and both ends enter the groove at the same time, so as to achieve the purpose of quickly and accurately placing the spring body 4 into the narrow groove on the plastic part 3, and effectively avoid the situation where one end jumps out in the compressed state, and the installation can be successful in one time, which reduces the labor intensity of the staff and greatly improves the work efficiency. In addition, the structure is stable and easy to operate, and it has certain practical value.

[0025] The specific operation is as follows: first, the plastic part 3 is placed in the positioning groove 151, and then the spring body 4 is placed in the positioning frame 141. Subsequently, the first cylinder 17 is opened, and the moving block 15 is pulled closer to the sliding block 14 so that the positioning groove 151 is located directly below the positioning frame 141. Then the moving block 15 pushes the sliding block 14 to move toward the side of the support seat 21. The push rod 22 squeezes and compresses the spring body 4 in the positioning frame 141. At the same time, the return spring 23 is compressed under the squeezing of the sliding block 14 until the positioning frame 141 and the positioning groove 151 are located directly below the pressing block 26. Subsequently, the second cylinder 24 is opened, and the L-shaped plate 25 drives the pressing block 26 to move downward, squeezing the compressed spring body 4 out of the positioning frame 141, and then directly pressing it into the groove of the plastic part 3 to complete the assembly.
