Description

Technical Field

[0001] The invention relates to a valve linkage regulating device. Background Art

[0002] In the steel ball heating furnace, multiple gases and air need to be mixed for combustion, and the heat generated by the combustion is used to heat the steel balls.

[0003] In multiple gas pipelines, the ratio of gas is set according to needs. When the temperature of the steel ball is too high or too low, the gas flow in each gas pipeline needs to be adjusted proportionally. By manually adjusting the valve opening, a single person adjusting multiple valves not only has low adjustment efficiency, but also cannot ensure that the gas can be increased or decreased proportionally synchronously, affecting the heating quality of the steel ball. Summary of the invention

[0010] Preferably, the connecting assembly includes a connecting shaft with one end spherically hinged to the connecting rod, a through hole opened in the connecting shaft and used for the movable rod to pass through, and a fixing bolt threadedly connected to the connecting shaft and with one end used to pass through the through hole to tighten the movable rod.

[0011] More preferably, the fixing bolt and the connecting shaft have the same axis and are perpendicular to the axis of the through hole.

[0012] More preferably, the axis directions of the movable rod and the through hole are parallel to each other.

[0013] Preferably, the pin shaft and the connecting rod have the same axis and are perpendicular to the length extension direction of the rotating rod.

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0022] See also Figure 1 As shown, the valve linkage adjustment device is used to perform linkage adjustment on valves 2 of at least two gas pipelines 1. In this embodiment, there are three gas pipelines 1, which are used to transport the first gas, the second gas and air respectively.

[0023] See also Figure 1-2As shown, the valve linkage regulating device comprises a movable rod 3, a driving mechanism for driving the movable rod 3 to move, and a regulating mechanism arranged between the movable rod 3 and the valve 2 in a one-to-one correspondence.

[0024] In this embodiment, the length extension directions of the three gas pipelines 1 are parallel to each other and perpendicular to the length extension direction of the movable rod 3. The gas pipelines 1 extend in the vertical direction, and the movable rod 3 extends in the horizontal direction.

[0025] See also Figure 1 As shown, the moving direction of the movable rod 3 is the direction of its own length extension, that is, the left-right direction.

[0026] The driving mechanism (not shown) includes a driving cylinder, a telescopic rod in the driving cylinder that can be extended and retracted along its own length, and the telescopic rod is coaxially connected to the movable rod 3. The movable rod 3 is driven to move in the left and right directions through the telescopic movement of the telescopic rod.

[0027] See also Figure 1 As shown, the above-mentioned adjustment mechanism includes a rotating rod 4 with one end fixedly connected to the valve 2, a long hole 5 opened in the rotating rod 4, a connecting component sleeved on the movable rod 3, a connecting rod 6 spherically hinged on the connecting component, a pin 7 fixedly connected to the connecting rod 6 and used to penetrate into the long hole 5, and a nut 8 threadedly connected to the pin 7 and used to tighten the rotating rod 4 to the connecting rod 6.

[0028] In this embodiment, the valve 2 is circular and can be adjusted in opening by rotating around its own axis. The rotating rod 4 is parallel to the radial direction of the rotating circle of the valve 2, that is, the opening of the valve 2 can also be adjusted by rotating the rotating rod 4. The length extension direction of the movable rod 3 is parallel to the rotation plane of the rotating rod 4. Through this setting, when the movable rod 3 moves, the rotating rod 4 only moves within its own rotation plane.

[0029] In this embodiment, the long hole 5 is parallel to the rotating rod 4 and is perpendicular to the coaxially arranged pin shaft 7 and the connecting rod 6 .

[0030] The position of the pin shaft 7 in the long hole 5 is set according to the ratio of the gas, that is, the rotation radius of the rotating rod 4 is set; when the movable rod 3 moves, since the rotation radius of the rotating rod 4 corresponds to the ratio of the gas one by one, the increase or decrease of the opening of the valve 2 corresponds to the gas ratio one by one, and the movement of a single movable rod 3 can ensure that the gas in the three gas pipelines 1 increases or decreases synchronously in proportion, and the regulation efficiency is high.

[0031] For a gas with a larger flow rate, the corresponding rotation radius of the rotating rod 4 is smaller, so that when the movable rod 3 moves the same distance, the rotating angle of the rotating rod 4 is larger;

[0032] For a gas with a smaller flow rate, the corresponding rotation radius of the rotating rod 4 is larger, so that when the movable rod 3 moves the same distance, the rotating angle of the rotating rod 4 is smaller.

[0033] See also Figure 2 As shown, the pin shaft 7 is fixedly connected to one end of the connecting rod 6 away from the connecting assembly, and the rotating rod 4 can be tightened between the nut 8 and the end of the connecting rod 6 through a nut 8 coaxially sleeved on the pin shaft 7.

[0034] See also Figure 2 As shown, the connection assembly comprises a connection shaft 9 with one end spherically hinged to the connection rod 6, a through hole 10 provided in the connection shaft 9 and used for the movable rod 3 to penetrate, and a fixing bolt 11 threadedly connected to the connection shaft 9 and one end of which is used to penetrate into the through hole 10 to tighten the movable rod 3. The axis directions of the movable rod 3 and the through hole 10 are parallel to each other.

[0035] The fixing bolt 11 is inserted into the end of the connecting shaft 9 away from the connecting rod 6, and one end of the fixing bolt 11 is inserted into the through hole 10. The fixing bolt 11 is coaxially arranged with the connecting shaft 9 and is perpendicular to the axis direction of the through hole 10. By adjusting the length of the fixing bolt 11 inserted into the through hole 10, the connecting shaft 9 and the movable rod 3 can be locked or disengaged with each other. The initial position of the connecting shaft 9 on the movable rod 3 is adjusted, that is, the initial position of the rotating rod 4 is adjusted, that is, the initial opening of the valve 2 is adjusted.

[0036] Through this configuration, the initial opening of the valve 2 can be adjusted according to the gas ratio in the three gas pipelines 1 .

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
