Vacancy.
Utility model content
The utility model overcomes a kind of the not enough there is provided tube built-in safety overflow valve of prior art presence, not only
Drawbacks described above is solved, and simple in construction, handling ease, system reconciles easy for installation.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of tube built-in safety overflow
Valve, including valve body, spring, steel ball valve, bonded washer and screw, the valve body lower portion are provided with external screw thread, and the external screw thread
With the expansion platform cylinder in the middle part of valve body, the top of the valve body is the structure of hexagonal prism, and the center of the valve body is provided with the rank of insertion
The upper end in terraced hole and hole is threaded, is provided with the shoulder hole and expands platform, and the expansion platform is located in the middle part of valve body and expands platform upper hole greatly,
The platform that expands in the shoulder hole is provided with four uniform spout holes vertical with its axis, four spout holes and valve body
Shoulder hole is communicated；
The steel ball valve, which is located in shoulder hole, to be expanded in the macropore on platform and with expanding platform sealing；In the steel ball valve and valve body
Shoulder hole is dynamic to be coordinated；The spring is cylinder stage clip；The screw is the interior hexagonal trip bolt that center sets through hole；The spring
Coaxial and expand successively mounted in valve body in platform hole with valve body respectively with screw, the spring and screw are respectively positioned on steel ball valve and spiral shell
Nail is connected firmly with valve body screw thread；The bonded washer is enclosed on outside valve body lower end screw thread and expands platform cylinder end face with valve body and touches.
The valve body is arranged in fuel tank so that screw will not be hit and by mistuning.
Through hole energy overflow simultaneously on four spout holes and screw on the valve body, and overflow is until in fuel tank.
The utility model has an advantageous effect in that compared with prior art：The utility model employs above-mentioned technical side
Case, makes tube built-in safety overflow valve, and production, system adjust convenient, and interchangeability is good, can produce by batch, and of the present utility model sets
Count principle simple, compact conformation, small volume is lightweight, good manufacturability, be easy to assembling, application space is big.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the utility model structure half section schematic diagram.
Fig. 2 is the utility model structure overflow situation schematic cross-sectional view.
In figure：1 it is valve body, 2 be spring, 3 be steel ball valve, 4 be bonded washer, 5 is screw.
Embodiment
As shown in Figure 1 and Figure 2, a kind of tube built-in safety overflow valve of the utility model, including valve body 1, spring 2, steel ball valve
3rd, bonded washer 4 and screw 5, the bottom of valve body 1 are provided with external screw thread, and the external screw thread and the expansion platform at the middle part of valve body 1 are justified
Post, the top of the valve body 1 is the structure of hexagonal prism, shoulder hole of the center provided with insertion and the upper end band in hole of the valve body 1
It is provided with screw thread, the shoulder hole and expands platform, and the expansion platform is located at the middle part of valve body 1 and expands platform upper hole greatly, in the shoulder hole
Expand platform and be provided with four uniform spout holes vertical with its axis, four spout holes are communicated with the shoulder hole in valve body 1；
The steel ball valve 3, which is located in shoulder hole, to be expanded in the macropore on platform and with expanding platform sealing；The steel ball valve 3 and valve body 1
Interior shoulder hole is dynamic to be coordinated；The spring 2 is cylinder stage clip；The screw 5 is the interior hexagonal trip bolt that center sets through hole；Institute
State spring 2 and screw 5 coaxial and expand successively mounted in valve body 1 in platform hole with valve body 1 respectively, the spring 2 and screw 5 are respectively positioned on steel
On pearl valve 3 and screw 5 is connected firmly with the screw thread of valve body 1；The bonded washer 4 is enclosed on outside the lower end screw thread of valve body 1 and expanded with valve body 1
Platform cylinder end face is touched.
The valve body 1 is arranged in fuel tank so that screw 5 will not be hit and by mistuning, and relative safety is good.
Through hole energy overflow simultaneously on four spout holes and screw 5 on the valve body 1, and overflow is up in fuel tank, it is oily
Road is with respect to shortcut.
The utility model is artificial firmly to manual pump Quick-pressing when reaching the off-load pressure of pre- setting, will not cause
Overflow is obstructed influence system pressure.
Its operation principle is：The lower end of valve body 1 is High Voltage liquid incoming port, and middle upper end is liquid flooding mouthful；When lower end
When liquid pressure reaches tube built-in safety overflow valve setting value, liquid pressure overcomes in the thrust that the bottom of steel ball valve 3 is produced
The frictional resistance of spring 2 and steel ball valve 3, moves up steel ball valve 3, and liquid is respectively from steel ball valve 3 and the gap of the formation of valve body 1
