Description

TECHNICAL FIELD

[0001] The utility model belongs to valve positioner installation technical field, especially a kind of installation for valve positioner. BACKGROUND

[0002] Valve positioner is a kind of automatic control device for controlling the opening of valve. It receives signals from the control system (such as electrical signals, air pressure signals, etc.), and then converts these signals into corresponding force to adjust the opening of valve. The installation structure of valve positioner is a support structure for connecting the positioner body with valve or actuator. The design of installation structure needs to consider the brand, type and size of regulating valve. At present, the brand, type, size and stroke of most regulating valves are different, which leads to the need for various positioner installation structures, and the installation structures cannot be used universally. When the regulating valve fails, it may not be replaced due to the difference in original positioner installation structure when replacing other brand and type of valve, which affects the timeliness of maintenance, and additional installation plate or other auxiliary structure is needed, which increases the installation difficulty and cost, thereby affecting the continuity of chemical production. SUMMARY

[0003] The utility model aims at providing a universal valve positioner installation, which can be used for the installation between valve positioner and regulating valve of different types, different sizes and strokes, without additional auxiliary structure, reducing the installation difficulty of valve positioner, improving the maintenance efficiency and saving the cost.

[0007] Further, one end of plane "L" shaped structure installation plate or one side linear end of plane "concave" shaped structure installation plate is detachably connected with regulating valve through connecting hole and bolt, and the other end of plane "L" shaped structure installation plate or the other side linear end opposite to plane "concave" shaped structure installation plate is detachably connected with positioner through connecting hole and bolt.

[0008] Further, the bolt passes through the connecting hole and the mounting hole on the adjusting valve and the positioner, and can slide along the central axis direction, and the position of the bolt is adjusted according to the distance of the mounting hole on the adjusting valve and the positioner. Thus, the installation of the adjusting valve and the positioner with different mounting hole distances is adapted.

[0009] Further, the long end of the planar "L" shaped structure mounting plate is provided with two connecting holes, and the short end of the planar "L" shaped structure mounting plate is provided with one connecting hole.

[0015] Further preferably, the inner and outer edges of the two ends of the planar "L" shaped structure mounting plate are in a slope, and the included angle between the slope and the two ends of the "L" shape is 135 degrees. Thus, the strength of the mounting plate is increased.

[0016] Further, the length of the long end of the planar "L" shaped structure mounting plate is 140-250mm, and the length of the short end is 120-160mm. Thus, the stroke distance of different types of adjusting valves and positioners can be adapted, and the versatility of the mounting part is improved.

[0017] Further preferably, the length of the long end of the planar "L" shaped structure mounting plate is 245mm, and the length of the short end is 155mm.

[0019] Further preferably, the length of the connecting hole is 55-80 mm and the width is 8-10 mm.

[0020] Further, the length of the opposite end of the concave edge of the flat concave structure mounting plate is 100-110 mm, and the length of the two ends connected with the regulating valve and the positioner is 60-80 mm.
