According to an aspect of the present utility model, being shaped as of described container 2 is square or circular.
According to an aspect of the present utility model, the horizontal plane of the top of described dividing plate and container 2 is on same horizontal plane.
According to an aspect of the present utility model, described inductor is infrared inductor.
According to an aspect of the present utility model, the outer wall of described container 2 is provided with the uniform scale of spacing.
The advantage that the utility model is implemented: because container 2 of the present utility model is airtight container, one end of valve is connected by pipe and air pressure, the other end of valve inserts in container 2 by pipe, the water surface of container 2 is provided with buoy, as long as buoy has atomic little external force to move, the both sides of the container outer wall at buoy place are provided with inductor, when having micro-leakage, blow the buoy in container 2, at this moment the very high inductor of sensitivity senses the movement of buoy immediately, thereby realize valve gas leakage measuring ability, therefore valve gas leak detection device is simple in structure, cheap, easy to operate, the degree of accuracy of testing result is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of a kind of valve gas leak detection device described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of valve gas leak detection device, described valve gas leak detection device comprises container 3, container 2 and valve 4 that water is housed, container 2 is airtight container, one end of valve 4 is connected by pipe and air pressure, and the other end of valve 4 inserts in container 2 by pipe; Container 3 is communicated with container 2 bottoms by pipe, and the horizontal plane of the horizontal plane of container 3 and container 2 is on same horizontal plane; The water surface of container 2 is provided with buoy 5, and the both sides of the container outer wall at buoy 5 places are provided with inductor 7.
In container 3 of the present utility model, be provided with major trough 6 and secondary groove 9, between major trough 6 and secondary groove 9, be provided with dividing plate 10, the horizontal plane of the top of dividing plate and container (2), on same horizontal plane, that is to say that the horizontal plane of major trough 6 and the horizontal plane of container 2 are on same horizontal plane; Major trough 6 is provided with water pump 1 with the bottom of secondary groove 9, at valve 4, leak gas before detection, if the water level in major trough 6 is on the low side, or when buoy 5 is excessive lower than the position of inductor 7, start water pump 1 draws water in major trough 6 in secondary groove 9, until the interior topped up with water of major trough 6 namely makes the horizontal plane of major trough 6 and the horizontal plane of container 2 on same horizontal plane.
In actual applications, being shaped as of container 2 is square or circular, and the bottom of container 2 and buoy 5 maintain a certain distance.Because buoy 5 is by PEC plastic production, as long as so buoy 5 has atomic little external force to move, when valve 4 has micro-leakage, detect gas and be pressed in container 2, blow the buoy 5 in container, if valve 4 leaks gas when large; the distance that buoy 5 moves is larger; on the contrary if valve 4 gas leakage hour, the distance that buoy 5 moves is very little.The both sides of container 2 outer walls at buoy 5 places are provided with inductor 7, the very high inductor 7 of sensitivity senses the movement of buoy 5 immediately, inductor 7 is delivered to the signal sensing the control apparatus of valve gas leak detection device, after control apparatus acceptance storage assembly, control apparatus stops detecting and reporting to the police, can realize the measuring ability that valve 6 leaks gas, without operator at the scene, realize automation and detect.In addition, in order to detect more intuitively, exactly, whether valve 4 leaks gas and the size of valve 4 air leakages, and the outer wall of container 2 is provided with the uniform scale 8 of spacing.
In addition, the preferred infrared inductor of inductor 7, it is by infrared reflection principle, when valve 6 leaks gas; buoy 5 rocks and makes part buoy 5 in infrared spectral range, and the infrared rays that infrared emission tube sends reflexes to infrared receiver tube because buoy 5 blocks, and sends to the control apparatus of valve gas leak detection device by the signal after treatment of the micro computer in integrated circuit; after control apparatus acknowledge(ment) signal, by the power supply of the main frame of the instruction closing control apparatus of specifying, main frame stops detecting and reporting to the police.
Working principle of the present utility model: due to the horizontal plane of major trough 6 all the time with the horizontal plane of container 2 on same horizontal plane, buoy 5 keeps static and can not rock, buoy 5 is by PEC plastic production, as long as so buoy 5 has atomic little external force to move, when valve 4 has micro-leakage, detecting gas is pressed in container 2, blow the buoy 5 in container, the both sides of container 2 outer walls at buoy 5 places are provided with inductor 7, the very high inductor 7 of sensitivity senses the movement of buoy 5 immediately, inductor 7 is delivered to the signal sensing the control apparatus of valve gas leak detection device, control apparatus stops detecting and reporting to the police, can realize the measuring ability that valve 6 leaks gas, without operator at the scene, realizing automation detects.
Use the beneficial effect of the utility model product:
