Abstract
The utility model relates to an LPG pouring balance. The upper end of the connecting rod of a lever mechanism is connected with a rack gear which is engaged with the gear wheel arranged on the center shaft of a machine core; one end of the center shaft is provided with a meter head pointer, and the other end is provided with the transmitting disk of a pneumatic system; two transmitting openings of a zero-point transmitting opening and an ending point transmitting opening are opened on the transmitting disk; therefore, the transmitting openings send out signals to the bidirectional amplifier of the pneumatic system to automatically control the pouring of liquid gas. Compared with the mechanical pouring balance which adopts a multi-stage lever structure, the utility model has the advantages of simple structure, high precision and high speed, and besides, the display of the meter head pointer is visual and the overall process of pouring measurement can be directly observed.
Description
The utility model relates to a kind of metering outfit, particularly a kind of city gas bottling scale.
Now metering is generally mechanical scale with scale during city gas bottling, and this mechanical scale adopts multi-grade lever to form the weight transfer system, and shows variable by arm beam of steelyard scale, this city gas bottling scale complex structure, and measuring accuracy is low, and speed is slow, and shows not directly perceived.
The purpose of this utility model provides a kind of city gas bottling scale of new structure, and it can overcome the above-mentioned shortcoming that exists in the prior art.
The purpose of this utility model is achieved in that it includes bearing platform, leverage, pneumatic system and gauge outfit, it is characterized in that the link rod upper end in the leverage links with a tooth bar, tooth bar is meshed with gear on the movement axis, gear and axis can mechanical attachment, also can adopt gear shaft, one end of axis is equipped with the pointer of gauge outfit, and the other end is equipped with the sender set of pneumatic system, has zero point on the sender set and stops two sender mouths.
The utility model adopts leverage and gas control to combine, the metering of realization auto-filling, more simple in structure than the mechanical type can scale that adopts the multi-grade lever structure, the measuring accuracy height, and speed is fast, owing to adopting gauge outfit, the utility model shows simultaneously, thus relatively more directly perceived, can observe directly the metering situation in the pouring process.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the general illustration of a kind of specific embodiment of the present utility model.
Fig. 2 is the structural representation of lever segment among the embodiment shown in Figure 1.
Fig. 3 is the structural representation of core section among the embodiment shown in Figure 1.
Fig. 4 is the right view of Fig. 3.
With reference to Fig. 1-4, introduce the detailed structure of present embodiment:
As seen from the figure, present embodiment comprises bearing platform 1, leverage, movement, gauge outfit 4 and pneumatic system 5, damper 6 is equipped with at the leverage middle part, can reduce the swing of meter pointer, link rod 7 above the damper links by tooth bar seat 8 and tooth bar 9, link rod top has spring 10 simultaneously, link with body, core section comprises axis 11, and axis is a gear shaft, its gear is meshed with above-mentioned tooth bar, one end of axis is equipped with the pointer 12 of gauge outfit, and the sender set 13 of pneumatic system is installed in the other end of axis, has two sender mouths on the sender set, one is initial sender mouth A, another when the bearing platform load-bearing is subjected to weight, moves downward tooth bar by link rod for stopping sender mouth B, the driven gear axle rotates, and meter pointer also together rotates identical angle with sender set.Pneumatic system adopts highly sensitive two-way amplifier as switching device, the conducting of control can valve and ending, the actuating signal of two-way amplifier is sent by signalling generator, signalling generator is made up of sender set and sender frame, the sender frame is divided into initial sender frame and stops the sender frame, initial sender frame 14 is screwed and is installed on the frame, its sender mouth just in time initial sender mouth A with sender set is relative, when making null position, the signal conducting stops sender frame 15 and is installed on the frame by slideway 16, when meter pointer refers at quantitative values, its sender mouth is relative with termination sender mouth B on the sender set, sends termination signal to two-way amplifier, otherwise signal interruption.Adjust the position of termination sender frame on slideway and just can change the termination quantitative values.Promptly when the liquid gas cylinder body weight does not wait, can adjust and stop the sender frame, the termination gravimetric value during with the change aeration can also when weight surpasses, send alerting signal stopping overload alarm of sender frame place installing.
Claims (3)
1, a kind of city gas bottling scale, it includes bearing platform, leverage and pneumatic system, it is characterized in that a link rod is arranged in the leverage, a link rod and a tooth bar link, tooth bar is meshed with gear on the movement axis, one end of movement axis is equipped with indicator, and the other end is equipped with the sender set of pneumatic system, has zero point on the sender set and stops two sender mouths.
2, city gas bottling scale according to claim 1 is characterized in that pneumatic system includes zero point and stops two sender framves, and slideway links between termination sender frame and the frame.
