Problems solved by technology

[0003] It can be seen from the above that the design of the door opening adjustment using the above method has the problems of designing the length of the connecting rod completely based on the experience of the designer, prolonging the design cycle, and seriously wasting human resources; The various components in the valve adjust the opening of the regulating door, and the following problems often occur: the actuator handle is prone to jamming during the process of fully opening and fully closing, and the value of the opening angle during the process of fully opening and fully closing the actuator handle Improper, longer connecting rod length, interference between the actuator and the regulating door, etc., which reduces the working reliability of the regulating door mechanism

Embodiment 1

[0051] Such as image 3 As shown, the preferred length L of the connecting rod is determined by the predetermined fully closed position N and the predetermined fully open position M, and the method adopted is as follows:

[0052] B1) Take the length r of the actuator handle as the radius, and make two circles with the predetermined fully open position M and the predetermined fully closed position N of the adjustable door handle as the center respectively, to obtain the intersection point P of the two circles, and then obtain the line segment PM and line segment PN , And the length of line segment PM and line segment PN are equal;

[0053] B2) Keep the relative positional relationship between the line segment PM and the line segment PN unchanged, and use the intersection point P as the base point to copy the line segment PM and the line segment PN respectively, so that the intersection point P and the rotation center O'of the actuator handle coincide after copying, so that the point ...

Embodiment 2

[0060] Such as Figure 5 As shown, in order to improve the control accuracy of adjusting the door opening, by adjusting the actuator handle length 5, the preferred opening angle γ of the actuator handle is 90°, using the following method:

[0061] D1) Make a straight line that intersects the angular bisector OG of ∠MON through the predetermined fully open position M and the predetermined fully closed position N of the adjustable door handle respectively, to obtain the intersection point P, and make ∠OPM and ∠OPN both 135°, thereby obtaining the line segment PM and line segment PN, and then get the length r of the actuator handle equal to the length of line segment PM and line segment PN;

[0062] D2) Keep the relative positional relationship between line segment PM and line segment PN unchanged, take point P as the base point, and copy line segment PM and line segment PN respectively, so that the intersection point P and the rotation center O'of the actuator handle coincide after co...

Embodiment 3

[0064] Such as Image 6 As shown, as a preference, in order to make the preferred opening angle γ of the actuator handle 90°, the method of adjusting the turning radius of the door handle can also be used, and the steps are as follows:

[0065] E1) Make two parallel lines located on both sides of the angular bisector OG of ∠MON, and the distance between the angular bisector OG and the angular bisector OG is Sin45°×r, and obtain the intersection M of a straight line and the straight line OM, and get parallel The intersection point N between another straight line in the line and the straight line ON, the predetermined fully open position M and the predetermined fully closed position N of the adjustment door handle are obtained, and then the line segment OM and the line segment ON are obtained, and the length equal to the line segment OM or the line segment ON is obtained Adjust the turning radius R of the door handle;

[0066] E2) Draw a straight line that intersects the angle bisect...

Abstract

The invention provides an adjusting method of an adjusting valve mechanism. The adjusting method comprises the following steps that an actuator handle with the length r rotates around a rotation circle center of the actuator handle at an optimized opening angle gamma of the actuator handle so as to enable the actuator handle to rotate from a preset full-closed position to a preset full-opening position; a connecting rod with the optimized length L performs corresponding motion under the driving of the actuator handle; an adjusting valve handle with rotation radius R rotates around a rotation circle center of the adjusting valve handle at an optimized opening angle 2beta of the adjusting valve handle under the driving of the connecting rod hinged to the adjusting valve handle so as to enable the adjusting valve handle to rotate from a preset full-closed position to a preset full-opening position and accordingly enable a guiding blade in the adjusting valve and connected with the adjusting valve handle through a control device to be switched from a full-closing state to a full-opening state. The optimized length L of the connecting rod is confirmed through the preset full-closed position and the preset full-opening position. The adjusting method is simple and easy and saves time and labor.

Description

Technical field [0001] The invention relates to the field of ventilator equipment, in particular to an adjustment method of an adjustment door mechanism. Background technique [0002] The circular petal-type regulating door mechanism is a commonly used regulating device in ventilator equipment, such as figure 1 As shown, the regulating door mechanism is mainly composed of the regulating door 1, the regulating door handle 2, the connecting rod 3, the actuator 4 and the actuator handle 5. The opening and closing of the regulating door mechanism is completed by the corresponding action of the actuator handle. Due to the different lengths of the handle of the adjusting door and the handle of the actuator, in the design of adjusting the opening of the door, the initial angle of the two cannot be simply set to be equal for the connecting rod design. The designer must have certain design experience. The current commonly used method is to adjust the door opening design based on experienc...
