Abstract
A double-butterfly-valve quantitative filling device is provided with two single-level butterfly valves. A through hole is arranged on a butterfly plate of one butterfly valve. The two butterfly valves are connected in series in use to achieve the double-level control function. The filling device is convenient to maintain and control and reduces investment cost.
Description
Technical field
The utility model relates to the quantitative filling device that two single-stage butterfly valves is combined into a twin-stage butterfly valve.
Background technology
The normal butterfly valve control pipeline that uses opens and closes in the pipeline conveying, and the opening and closing element of butterfly valve is a disc shaped butterfly plate that is positioned at passage, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate, main cut-out and the throttling action of rising on pipeline.Common butterfly valve only has standard-sized sheet and two kinds of mode of operations of full cut-off, but in process of production, requirement by production technology, need to carry out regulation and control to the flow of pipeline, this need to use the twin-stage diaphragm valve to realize, the twin-stage diaphragm valve has standard-sized sheet, half-open, three kinds of mode of operations of full cut-off, can realize throttling, satisfies different technological requirements.The twin-stage diaphragm valve uses and has following problem: 1, complex structure, and the control system that is used in conjunction with requires high; 2, maintenance cost is high; 3, involving great expense, is the input that is several times as much as the single-stage butterfly valve, increases use cost.
The utility model content
The technical problems to be solved in the utility model provides a kind of quantitative filling device that two single-stage butterfly valves is combined into a twin-stage butterfly valve, so that realize twin-stage control function, and reduce cost.
Described in the utility model pair of butterfly valve quantitative filling device, fluid pipeline is arranged, detect the flow counter of pipeline flow, flow counter is installed in the pipeline front-end position, two single-stage butterfly valves are arranged, and the first butterfly valve is existing single-stage butterfly valve, has through hole on the butterfly plate of the second butterfly valve, two butterfly valves are installed in the back segment of pipeline, and the second butterfly valve is positioned at after the first butterfly valve.
Described in the utility model pair of butterfly valve quantitative filling device, ducted liquid flow through successively flow counter, the first butterfly valve, the second butterfly valve, set the first and second two nodes in the bulking system, this two node can be timing node, or can amount node, flow through and to carry out throttling to pipeline liquid when the liquid of pipeline reaches first node, close pipeline when reaching Section Point.When can work began, two butterfly valves were opened, and it is maximum that ducted flow reaches; When flow counter detects first node, send a signal to the second butterfly valve it is closed, have through hole on the butterfly plate because of the second butterfly valve, can not the complete closed pipeline, liquid continues can with low discharge; When flow counter detects Section Point, send a signal to the first butterfly valve it is closed, thereby make pipe sealing, can stops.Its beneficial effect is: 1, realize standard-sized sheet, half-open, three kinds of mode of operations of full cut-off by two single-stage butterfly valves, satisfy the technological requirement of producing; 2, apparatus structure is simple, is convenient to safeguard, controls and uses; 3, effectively reduce manufacturing cost and maintenance cost, reduce and drop into.
Description of drawings
Fig. 1 is the structural representation of two butterfly valve quantitative filling devices.
Fig. 2 is the partial enlarged drawing of shown in Figure 1 pair of butterfly valve quantitative filling device.
The specific embodiment
Described in the utility model pair of butterfly valve quantitative filling device, fluid pipeline 1 is arranged, detect the flow counter 2 of pipeline flow, flow counter 2 is installed in pipeline 1 front-end position, and two single-stage butterfly valves are arranged, and the first butterfly valve 3 is existing single-stage butterfly valves, have through hole 42 on the butterfly plate 41 of the second butterfly valve 4, two butterfly valves 41,42 are installed in the back segment of pipeline 1, and the second butterfly valve 4 is positioned at after the first butterfly valve 3, the liquid in the pipeline 1 flow through successively flow counter 2, the first butterfly valve 3, the second butterfly valve 4.
Set the first and second two nodes in the bulking system, this two node can be timing node, or can amount node, need to carry out throttling to pipeline liquid when the liquid of the pipeline 1 of flowing through reaches first node, closes pipeline 1 when reaching Section Point.When can work began, two butterfly valves 41,42 were opened, and it is maximum that the flow in the pipeline 1 reaches; When flow counter 2 detects first node, send a signal to the second butterfly valve 4 it is closed, have through hole 42 on the butterfly plate 41 because of the second butterfly valve, can not complete closed pipeline 1, liquid continues can with low discharge; When flow counter 2 detects Section Point, send a signal to the first butterfly valve 3 it is closed, thereby make pipeline 1 sealing, can stops.
Claims (1)
1. two butterfly valve quantitative filling device, fluid pipeline (1) is arranged, detect the flow counter (2) of pipeline flow, flow counter (2) is installed in pipeline (1) front-end position, it is characterized in that: two single-stage butterfly valves are arranged, and the first butterfly valve (3) is existing single-stage butterfly valve, has through hole (42) on the butterfly plate (41) of the second butterfly valve (4), two butterfly valves (41,42) are installed in the back segment of pipeline (1), and the second butterfly valve (4) is positioned at the first butterfly valve (3) afterwards.
