Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figs 1-4, a kind of oil tank air tightness detector, including detection cylinder 1 and display box 2, display box 2 are welded on
1 side of cylinder is detected, detects in cylinder 1 and is provided with cavity, thick screw rod 3 is provided in cavity, cavity top is provided with screw socket 4, thick spiral shell
Bar 3 is meshed by screw thread with screw socket 4, and cavity bottom is provided with port 5, and 5 bottom of port is welded with air pipe head 6, display box 2
Bottom is provided with storage chamber 7, and guiding gutter 1 and guiding gutter 29 are provided at the top of storage chamber 7, detects and is provided with through-hole on cylinder 1
10, through-hole 10 is communicated with guiding gutter 29, and receiving slot 1 and receiving slot 2 12 are provided on display box 2, slot 1 is received and leads
Sink 1 communicates, and receiving slot 2 12 is communicated with guiding gutter 29, is welded by spring 13 in receiving slot 1 and receiving slot 2 12
It is connected to block 14, venthole 15 is provided on block 14.
Press head 16 is welded at the top of block 14, the distance between press head 16 and detection cylinder 1 are equal to venthole 15 and lead
The distance between sink 1, therefore can allow between venthole 15 and guiding gutter 1 and guiding gutter 29 and communicate, and then make water storage
Water body flow in chamber 7；Thick 3 bottom of screw rod is arranged with Rubber end 17, and Rubber end 17 is fastened in cavity, therefore can guarantee rubber
First 17 both sides sealing is good；It is provided with annular groove on air pipe head 6, rubber layer 18,6 front end of air pipe head are arranged on annular groove
It is arranged with rubber ring 19, so as to use rubber ring 19 to guarantee that leakproofness is preferable between reservoir port and air pipe head 6；Thick screw rod
3 tops, which are welded with, turns first 20, and detection 1 side of cylinder is welded with handle 21；The length of thick screw rod 3 is less than the length of detection cylinder 1, shows
Show and be provided with observation panel 22 on front side of box 2, therefore water level in guiding gutter 1 and guiding gutter 29 can be observed by observation panel 22 and become
Change situation；Air pipe head 6 is truncated conical shape, therefore can be suitable for most of fuel tank, and block 14 is rectangular shape, Neng Goubao
Demonstrate,prove sealing effect.
Utility model works principle: it is when the utility model is used, reservoir port is upward, then air pipe head 6 is inserted into
In reservoir port, since air pipe head 6 is truncated conical shape, radius is gradually increased, therefore can be suitable for most of fuel tank, after being seated
Connecting portion is covered using rubber ring 19, so as to guarantee that interface air-tightness is good, is then turned thick screw rod 3 upwards,
Due to being communicated in fuel tank and cavity, negative pressure can be generated in fuel tank, receiving slot 1 is then pressed simultaneously using finger and holds
The block 14 in slot 2 12 is put, therefore venthole 15 can be communicated with guiding gutter 1 with guiding gutter 29, therefore negative in fuel tank
The enough water by storage chamber 7 and guiding gutter 1 of pressure energy is pumped into guiding gutter 29, therefore the water level in guiding gutter 29 is apparently higher than
Water level in guiding gutter 1, if the water level in guiding gutter 29 remains unchanged, fuel tank internal air-tightness is good, if guiding gutter 29
Interior water level slowly falls and finally resets, then it represents that there are gas leakage situations for fuel tank, and water level falling speed is faster, then it represents that
Gas leakage situation is more serious, the utility model structure novel, can judge the air-tightness and gas leakage situation of fuel tank, easy to operate, makes
With conveniently.
The above are the preferable embodiment of the utility model, the utility model those skilled in the art can also be to upper
It states embodiment to change and modify, therefore, the utility model is not limited to above-mentioned specific embodiment, all abilities
Field technique personnel made any conspicuous improvement, replacement or modification on the basis of the utility model belong to practical
Novel protection scope.
