Detailed description of the invention
Below in conjunction with embodiment, the utility model is elaborated.
The utility model leak detector is for the leakage investigation of rolling stock vacuum feces collecting device, this leak detector by with dirt box on airtight joining of blowoff valve delivery outlet, realize blowoff valve whether to exist to leak checking.
Fig. 2, Figure 3 shows that the utility model leak detector embodiment 1.
As shown in FIG., this leak detector comprises Connection Block 4, and Connection Block 4 is the tubular of an end opening, one end sealing,, is provided with ring-shaped flexible seal pad 7 at cylinder the end, and Tong Di center is provided with screwed hole, and by this screwed hole, air gauge 5 is installed. On the sidewall of tubular Connection Block 4, symmetrical its tubular axle center is provided with two interface arrangments, this interface arrangment comprises bearing 9, bearing pin 10, dop 11, bearing 9 one on the sidewall of tubular Connection Block 4 is made, dop 11 is rotatably arranged on bearing 9 by bearing pin 10, and can the radially wobbling along tubular Connection Block 4 cylindrical shells around bearing pin 10, on dop 11, with operating grip 11.1, on the sidewall of tubular Connection Block 4, have the through hole passing for dop 11.
The dial plate of air gauge 5 is back to the lateral surface setting at the cylinder end of tubular Connection Block 4.
On lateral surface at the bottom of 4 of tubular Connection Blocks, be provided with fender bracket 6, this fender bracket 6 is made up of four poles 6.2 of ring 6.1 and connecting ring 6.1 and cylinder end lateral surface, and four poles 6.2 are spaced along ring 6.1, and air gauge 5 is positioned at fender bracket 6.
As shown in Figure 4, when the leak detector of embodiment 1 uses, first move the handle 11.1 of two dops 11, make dop 11 at the inner chamber that radially exits tubular Connection Block 4 completely, then Connection Block 4 covers are installed on the delivery outlet pipeline section 3 of the blowoff valve 2 on dirt box 1, and make pressured joint of end face of sealing gasket 7 and delivery outlet pipeline section 3, rotate subsequently two dops 11 and snapped in the annular groove 3.1 on delivery outlet pipeline section 3, and thus leak detector and delivery outlet pipeline section 3 are fixed.
Along with sealing gasket 7 and pressured joint of end face of delivery outlet pipeline section 3, thus by hermetic closed the delivery outlet pipeline section 3 of blowoff valve 2,5 of air gauges are by the screwed hole of centre at the bottom of 4 of tubular Connection Blocks and the intracavity inter-connection of delivery outlet pipeline section 3.
Now, if blowoff valve 2 cuts out well, do not leak, the numerical value of air gauge 5 will can not change; And if blowoff valve 2 is not closed completely and exist leakage, the numerical value of air gauge 5 will occur changing, exists and leak and indicate in real time, intuitively blowoff valve 2.
On tubular Connection Block 4, fender bracket 6 is except in being enclosed in air gauge 5, prevent that it from being collided with outside, the hand held structures of this fender bracket 6 during also simultaneously as operation, for the use of leak detector facilitates.
Fig. 5 is the embodiment 2 of the utility model leak detector, and compared with embodiment 1, the direction of operating of the dop 11 of embodiment 2 is contrary. Dop 11 in Fig. 5 in delivery outlet pipeline section 3 on the state that departs from of annular groove 3.1, dop 11 overturns downwards, will enter and the state of annular groove 3.1 clampings. Referring to Fig. 4, the dop 11 in embodiment 1 upwards overturns and enters and the state of annular groove 3.1 clampings, and upset downwards will enter the state departing from annular groove 3.1.
In addition, the embodiment of the utility model leak detector is except above-mentioned two embodiment, also comprise that those of ordinary skill in the art make multiple different embodiment after comprehension the utility model thought, if do not adopted the Connection Block 4 of tubular, as made dop 11 realize automatic clamping by back-moving spring is set, etc.
As the quick-speed leak detection method of rolling stock vacuum feces collecting device leakage failure, the core of the utility model method is: when leakage failure appears in the empty shit gathering equipment of taking seriously, first the blowoff valve on dirt box is checked, and do not exist after leakage at definite blowoff valve, then other positions of vacuum system in vacuum feces collecting device are investigated. Like this, can determine the reason that 90% above vacuum feces collecting device leaks, reduce maintenance personal's workload, improve and leak investigation efficiency, improve maintenance efficiency.
Except the leak detector shown in embodiment 1, the utility model quick-speed leak detection method also can use the leak detector of other appropriate formats.
In the past only in the time there is leakage failure, cisco unity malfunction in rolling stock vacuum feces collecting device, just it is carried out to maintenance and inspection, and utilize the utility model method to carry out current check, can get rid of in time the leakage hidden danger of 90% above vacuum feces collecting device, both ensured that vacuum feces collecting device normally worked, also can make to exist the blowoff valve of leakage problem to be repaired in time, result in greater loss avoiding.
Be understandable that, above embodiment is only used to principle of the present utility model is described and the illustrative embodiments that adopts, and the utility model is not limited to this. For those skilled in the art, in the situation that not departing from principle of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
