Problems solved by technology

In addition, the current wind-air linkage valve needs to remove the chain to perform tooth-reversing operation during the air-air adjustment, which is very troublesome, and the adjustment can only be performed in multiples of teeth, and the accuracy is very low

specific Embodiment 1

[0016] Rotary barrel air valve we use image 3 For the column, we take the multi-way ball valve as Figure 6 as a column, the stove head is Figure 7 For the column, the premixed combustion method, the air inlet 1, the furnace body 4, the premixed chamber 6, the fire outlet 29, and the air inlet 31 in the figure, we first put Figure 6 The 2 air outlets 11,12 of the middle multi-way ball valve are connected together, and then connected with Figure 7 The air inlets 1 in are connected together to form an air supply circuit, and then the image 3 The air outlet 62 in Fig. 7 is connected with the air inlet 31 to form an air supply circuit, and then the valve ball shaft 44 of the multi-way ball valve and the air valve shaft 64 are connected together by gears and chains to realize the air linkage. The air valves are all in the closed state. The debugging process of the low-fire working point is as follows. When we turn the handle 43 of the multi-way ball valve counterclockwise,...

Embodiment 2

[0018] Stove with Figure 8 As a column, it is a shared air chamber type combined burner head, with 2 combustion units, and the central small fire is an external mixed combustion method. In the figure, the air inlets 1, 22, the furnace body 4, the external mixing chamber 16, and the external mixing air outlet 19. Shared air cavity 21, air outlet 28, furnace head air inlet 31, multi-way ball valve with Figure 6 For the column, 2-way air outlet, rotary bucket air valve with image 3 As a column, we first connect the air inlets 1, 22 of the burner head and the air outlets 11, 12 of the multi-way ball valve together according to the same single digit, and then connect the air inlet 31 of the burner head with the outlet of the air valve. The tuyere 62 is connected, and then the valve ball shaft 44 of the multi-way ball valve and the valve cylinder shaft 64 of the rotary bucket air valve are connected together by gears and chains to realize air linkage, and the current air valves ...

specific Embodiment 3

[0020] Rotary barrel air valve we use image 3 as a column, the stove head is Figure 7 In the figure, the air inlet 1, the furnace body 4, the premix chamber 6, the fire outlet 29, the air inlet 31, and the air supply valve we use ordinary ball valves for air supply, air passage, air passage and the connection of the air linkage device. The existing technology is the same. The current air valves are all closed. The debugging process of the low fire working point is as follows. When we turn the handle of the ball valve counterclockwise, the air valve shaft 64 rotates synchronously, and the air valves are gradually opened. 6 Synchronously supply wind and air, and the small fire starts to burn. At this time, we loosen the top wire 5 of the wheel sleeve to disengage the wheel sleeve and the damper shaft 64. We manually adjust the handle of the ball valve and the damper shaft 64 respectively, so that the small The fire burns in the best condition, and the loosened wheel sleeve to...

Abstract

A rotary bucket air valve, which is composed of a valve body, a rotary bucket, a rotary bucket shaft, etc., is characterized in that: on one side of the rotary bucket shaft, there is an L-shaped support frame, and a rotary bucket shaft hole is provided on the support frame, and the rotary bucket shaft hole is arranged on the support frame. A drive wheel and a wheel sleeve are sheathed on the barrel shaft, a positioning device is arranged on the wheel sleeve, and the flow hole on the valve barrel is a long flow hole. Due to the adoption of the above scheme, the transmission mechanism can work stably for a long time, and the output characteristic of the air valve becomes linear, making it easier and more convenient for the air valve and the air valve to adjust the air ratio.

Description

technical field [0001] The invention relates to a damper for a blast stove. Background technique [0002] There is basically only one type of wind-operated air valve used on the current blast stove, which is a butterfly air valve and a rotary leaf air valve. See figure 1 , its structure is simple, its cost is low, and it is easy to install. The biggest disadvantage is serious nonlinearity. According to the output characteristic curve of the butterfly valve, when the butterfly valve is opened at 50%, its flow rate is already close to 90%, which can be seen in the adjustment process of the last 50%. , the flow rate does not change much, reaching a negligible level. Such a damper can still be used as a manual adjustment valve, but if it is used as a wind-air linkage valve, there is no wind to adjust in the second half, just as a It's just a look and has no real meaning. This is one of the places to be improved in this patent. In addition, the current wind-air linkage valve n...
