Description

Technical Field

[0001] The utility model relates to the field of electric control valve disassembly and assembly tools, in particular to a special tool for rotating and adjusting an electric control valve. Background Art

[0002] A large number of electric control valves are used in the power and energy supply pipelines of tobacco factories. They are mainly composed of valve heads, valve seats, and valve bodies. When using or replacing electric control valves and related pipelines in normal times, the electric control valves need to be rotated a certain angle to the appropriate position for easy operation.

[0003] In the past, when the angle needed to be adjusted, operators would generally move the cylindrical valve head above the electric control valve. On the one hand, due to its cylindrical structure and smooth surface, it was impossible to apply force reliably. On the other hand, the valve head in use was made of metal, and the surface temperature was high, posing a risk of scalding.

[0004] Due to these two reasons, operators usually move the plastic electrical junction box on the valve head for rotational adjustment. However, due to improper force, the shell of the electrical junction box is often damaged. Utility Model Content

[0005] In view of the above, the utility model aims to provide a special tool for rotating and adjusting an electric control valve to solve the above-mentioned technical problems.

[0006] The technical solution adopted by the utility model is as follows:

[0008] A second clamping arm is also provided on the force applying rod, and the second clamping arm is connected to the force applying rod through an adjusting mechanism, and the adjusting mechanism is used to adjust the position and angle of the second clamping arm on the force applying rod;

[0009] A plurality of second convex teeth are disposed on the inner side of the second clamping arm, and the second convex teeth are opposite to the first convex teeth.

[0010] In at least one possible implementation, the adjustment mechanism includes a long hole groove and a locking device provided on the rod body of the force application rod;

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0021] The utility model provides an embodiment of a special tool for rotating and adjusting an electric control valve. Specifically, Figure 1 and Figure 2 As shown, it includes: a force applying rod 1 (preferably, firstly, a telescopic mechanism can be provided on the rod body of the force applying rod 1 to increase the length of the rod body to increase the torque. The scheme of lengthening the rod body by the telescopic mechanism belongs to a mature technology in the mechanical field, and the present utility model does not limit this. Secondly, an anti-slip rubber sleeve can be added to the gripping part of the rod body or a knurling treatment can be directly performed on the surface of the rod body to form a knurled surface to increase friction and facilitate operation).

[0022] A first clamping arm 2 is installed on the top of the force applying rod 1 (in some embodiments, the two can be integrally formed), and there is a fixed angle between the first clamping arm 2 and the force applying rod 1, and a plurality of first convex teeth 21 are arranged on the inner side of the first clamping arm 2, and the first convex teeth 21 cooperate with the stepped grooves on the connecting plate on one side of the valve seat of the electric control valve; the aforementioned fixed angle is consistent with the angle of the connecting plate on the valve seat, that is, to ensure that the inner surface of the first clamping arm 2 with the first convex teeth 21 is reliably in contact with the connecting plate on the valve seat.

[0023] The force-applying rod 1 is also connected to a second clamping arm 3, which is connected to the force-applying rod 1 through an adjustment mechanism, and the adjustment mechanism is used to adjust the position, angle, and angle of the second clamping arm 3 on the force-applying rod 1 relative to the first clamping arm 2, that is, it can be understood that the first clamping arm 2 is fixed, and the second clamping arm 3 is movable, and the spacing, angle, etc. relative to the first clamping arm 2 can be adjusted as needed. In actual operation, the adjustment mechanism includes a long hole slot 11 and a locking device (not shown in the figure) provided on the rod body of the force-applying rod 1. One end of the second clamping arm 3 passes through the long hole slot 11 and can move. After being adjusted to the desired position and angle, it can be locked by the locking device.

[0024] Continuing from the previous text, a plurality of second convex tooth portions 31 are provided on the inner side of the second clamping arm 3, and the second convex tooth portion 31 is opposite to the first convex tooth portion 21, and is used to cooperate with the stepped groove on the connecting plate on the other side of the valve seat of the electric control valve (those skilled in the art can understand that the valve seat of the electric control valve targeted by the utility model has two symmetrically inclined connecting plates respectively formed with stepped grooves).

[0025] Based on the above embodiments, the following schematic description is given here of the use of the special tool: Taking the attached figure as an example, when using the tool, hold it horizontally, first make the first clamping arm close to the connecting plate on one side of the valve seat, and clamp the first convex tooth part in the stepped groove on the connecting plate on this side, then move and adjust the position and angle of the second clamping arm, so that it gradually approaches the connecting plate on the other side of the valve seat, until the second convex tooth part is clamped in the stepped groove on the connecting plate on this side, and the second clamping arm is locked. In this way, the operator can apply the force to the valve seat and bring the valve seat and the valve head above it to rotate by holding the rod body of the force rod and applying torque, without having to apply force to the valve head to rotate the electric control valve.

[0026] In summary, the main design concept of the utility model is that it includes a force rod and a first clamping arm installed on the top of the force rod, the first clamping arm and the force rod have a fixed angle, and the inner side of the first clamping arm is provided with a plurality of first convex teeth; a second clamping arm is also provided on the force rod, the second clamping arm is connected to the force rod through an adjustment mechanism, and the adjustment mechanism is used to adjust the position and angle of the second clamping arm on the force rod; the inner side of the second clamping arm is provided with a plurality of second convex teeth, and the second convex teeth are opposite to the first convex teeth. Using this special tool, on the one hand, there is no need for the hand to directly touch the electric control valve, thereby avoiding burns; on the other hand, using the special tool to move and rotate the metal valve seat avoids damage to the plastic electrical junction box.
