Description

Technical Field

[0001] The present invention relates to the field of valve control, and in particular to a butterfly valve opening sensor bracket. Background Art

[0002] In the prior art, the opening of a butterfly valve is generally measured on-site. With the advancement of technology and the improvement of automatic control requirements, on-site observation can no longer meet the requirements. It is a general trend to transmit valve opening data wirelessly. The patent of this invention is a valve opening sensor bracket, which effectively solves the installation problem of the valve opening sensor. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a valve opening sensor bracket, which is installed on the valve operator and accurately transmits the rotation angle of the valve operator to the valve opening sensor.

[0004] In order to solve the above technical problems, the present invention provides a valve opening sensor bracket, which is composed of a fixed bracket, a bow bracket, and a connector. The fixed bracket is composed of a base plate, a top plate, and a support plate. The base plate is installed on the valve opening operator with screws through grooves or holes. The top plate is provided with a slide groove. The valve opening sensor is fixed on the top plate through the slide groove. The valve opening sensor can adapt to valve operators of different diameters by sliding in the slide groove. The support plate connects the base plate and the top plate to control the spatial position of the top plate.

[0005] Furthermore, the arched bracket has a mounting hole and a connecting hole, the arched bracket is fixed to the rotating shaft of the valve operator through the mounting hole and rotates with the rotating shaft, and the connecting hole of the arched bracket is reliably connected to the connector.

[0006] Furthermore, one end of the connector is connected to the bow-shaped bracket, and the other end is connected to the turntable of the valve opening sensor, so that the bow-shaped bracket and the turntable of the valve opening sensor rotate synchronously.

[0007] Compared with the prior art, the present invention has a positive and obvious effect. The present invention uses the valve operator end cover fixing screws to install the fixing bracket, and the valve opening sensor slides in the slide slot to adapt to valve operators of different diameters. The use of the arched bracket increases the installation space and makes the installation faster, more convenient and more reliable. The present invention has the advantages of simple structure, easy installation and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a valve opening sensor bracket is composed of a fixed bracket, a bow bracket, and a connector. The fixed bracket is composed of a bottom plate 3, a top plate 1, and a support plate 4. The bottom plate 3 is installed on the end surface of the valve opening operator through a groove or hole 5 using the valve operator end cover screws. The top plate 1 has a slide groove 2. The valve opening sensor is fixed to the top plate 1 with screws through the slide groove 2. The valve opening sensor adapts to valve operators of different diameters by sliding in the slide groove 2. The support plate 4 connects the bottom plate 3 and the top plate 1 to control the spatial position of the top plate 1.

[0017] Furthermore, the arch bracket 6 has a mounting hole 8 and a connecting hole 7. The arch bracket 6 is fixed to the rotating shaft of the valve operator by screws through the mounting hole 8 and rotates with the rotating shaft. The connecting hole 7 of the arch bracket 6 is reliably connected to the connector.

[0018] Furthermore, one end of the connector is connected to the arch bracket 6, and the other end is connected to the turntable of the valve opening sensor, so that the arch bracket 6 and the turntable of the valve opening sensor rotate synchronously.

[0019] Before installation, first adjust the valve operator to the fully open or closed state, reliably connect the bow bracket 6 and the connector, then install the bow bracket on the rotating shaft of the valve operator, and the fixed bracket is installed on the end face of the valve opening operator using the valve operator end cover screws through the groove or hole 5. After the valve opening sensor and the connector are reliably connected, install the valve opening sensor into the slide groove 2 of the fixed bracket, adjust the position of the valve opening sensor on the slide groove 2, align the axis of the connector with the center of the bow bracket connecting hole 7, rotate the connector to make the rotating shaft angle of the valve operator consistent with the angle displayed by the valve opening sensor, reliably connect the connector and the bow bracket, and finally, turn on the valve opening sensor system to accurately adjust the consistency between the rotating shaft angle of the valve operator and the angle displayed by the valve opening sensor.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that as long as the valve operator bracket is installed using the valve operator shaft and the valve operator end screws, other structural forms are also within the protection scope of the present invention.
