[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figures 1-5 This utility model provides an electric valve positioner with dual control boards, including a housing 1 and a cover 2. The side of the housing 1 is provided with a terminal block 3 and an actuator terminal block 4. The housing 1 and the cover 2 are interlocked. The side of the housing 1 has two mounting slots that are adapted to the terminal block 3 and the actuator terminal block 4. A button is provided at the bottom of the front of the cover 2.

[0022] In this embodiment, the outer shell 1 and the face cover 2 are detachably fixedly connected. The output terminal block 3 is a 6P output terminal block, and the output terminal block 3 is connected to the DC signal source, DC ammeter and power supply. The actuator terminal block 4 is a 6P actuator terminal block, and the actuator terminal block 4 is connected to the actuator. The button on the bottom of the front of the face cover 2 is used for manual operation by the operator.

[0023] The housing 1 has a dual control board structure inside, which includes a first PC control board 5 and a second PC control board 6. The bottom and top of the front of the first PC control board 5 are respectively provided with a button module 9 and a display module 10. The second PC control board 6 is connected to the outgoing terminal block 3 and the actuator terminal block 4. The front of both the first PC control board 5 and the second PC control board 6 are fixedly connected with a processing module 11.

[0024] In this embodiment, the first PC control board 5 is used to process and analyze current signals and key input signals. The key module 9 corresponds to the key on the bottom of the front of the cover 2, which facilitates manual operation by the staff. The display module 10 is used to display data information. The processing module 11 is used to analyze and process the signals received by the first PC control board 5 and the second PC control board 6. The processing module 11 is an existing product structure. The second PC control board 6 is used to transmit command signals to the actuator, thereby controlling the operation of the actuator.

[0025] PC control board 5 and PC control board 6 are connected by guide post 7. The guide post 7 is made of metal and its two ends are connected to PC control board 5 and PC control board 6 respectively. PC control board 5 and PC control board 6 are parallel to each other. The end of the guide post 7 is provided with a fixing component 8. The fixing component 8 includes a connecting sleeve 81. The bottom of the inner cavity of the connecting sleeve 81 is fixedly connected to a guide block 82. The connecting sleeve 81 and the guide post 7 are sleeved together. The connecting sleeve 81 is made of plastic. The guide block 82 is made of metal and the end of the guide block 82 is in contact with the end of the guide post 7. A rubber ring 83 is fixedly sleeved inside the connecting sleeve 81 and an extrusion block 84 is fixedly connected to the inner side of the connecting sleeve 81. The rubber ring 83 is movably sleeved on the outside of the guide post 7. The extrusion block 84 is made of silicone and the contact surface between the extrusion block 84 and the guide post 7 is arc-shaped.

[0026] In this embodiment, the connecting sleeve 81 is fixedly connected to the first PC control board 5 and the second PC control board 6 respectively, and the guide block 82 inside the connecting sleeve 81 is also fixedly connected to the first PC control board 5 and the second PC control board 6 respectively. In this way, when the first PC control board 5 and the second PC control board 6 are fixed together by the guide post 7, the electrical signal between the first PC control board 5 and the second PC control board 6 can be transmitted and exchanged through the connection between the guide block 82 and the guide post 7.

[0027] Simultaneously, when the end of the guide post 7 is inserted into the connecting sleeve 81, the silicone extrusion block 84 will first undergo extrusion deformation and extrude and fix the side of the guide post 7. As the guide post 7 continues to extend, it will be fitted onto the outside of the rubber ring 83. The elasticity of the rubber ring 83 itself will also extrude and fix the outside of the guide post 7 until the end of the guide post 7 and the guide block 82 come into contact. At this time, the double extrusion of the extrusion block 84 and the rubber ring 83 can increase the friction of the surface of the guide post 7, so that the guide post 7 can be firmly fixed. This facilitates a stable connection between the first PC control board 5 and the second PC control board 6.

[0028] The working principle and usage process of this utility model are as follows: First, when assembling the electric valve positioner, insert one end of the guide post 7 into the connecting sleeve 81 on the first PC control board 5, so that one end of the guide post 7 extends continuously until one end of the guide post 7 contacts the guide block 82 on the first PC control board 5. At this time, the squeezing block 84 and the rubber ring 83 inside the connecting sleeve 81 will double squeeze and fix one end of the guide post 7.

[0029] Next, insert the other end of the guide post 7 into the connecting sleeve 81 on the second PC control board 6, so that the other end of the guide post 7 continues to extend until the other end of the guide post 7 contacts the guide block 82 on the second PC control board 6. At this time, the compression block 84 and the rubber ring 83 inside the connecting sleeve 81 will double compress and fix the other end of the guide post 7, thus achieving a stable connection between the first PC control board 5 and the second PC control board 6, that is, assembling the dual control board structure;

[0030] Finally, the terminal block 3 and the actuator terminal block 4 are welded to one side of the second PC control board 6, and the assembled dual control board structure is placed inside the housing 1, so that the terminal block 3 and the actuator terminal block 4 on the dual control board structure are respectively snapped into the two mounting slots opened on the side of the housing 1. Then, the cover 2 is closed and pressed down to make the cover 2 and the housing 1 snapped and fixed, thus completing the assembly of the electric valve positioner.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
