Abstract

The utility model provides a multifunctional manometer belonging to a device for measuring pressure, which is characterized in that a metering main body An is connected with a cylinder pressure feeler B, a tyre pressure feeler C and a pipeline pressure connection tube (joint) D respectively to measure the pressure of an air cylinder, a tyre and a braking pipeline. When the measured tyre pressure is insufficient or too high, the tyre can be inflated and deflated directly to reach the specified value. As a result, the service life, the economic benefit and security of the automobile are enhanced. The compressed air in the air receiver of the own automobile or other compressed air can be used as an air source so that the self aid ability can be enhanced.

Description

Multifunctional manometer

The utility model belongs to a kind of barometric surveying device.Be mainly used in the measurement of automobile cylinder pressure, tire pressure, pneumatic brake line pressure.Simultaneously, if under-inflation, this device can link to each other to inflation of tire with source of the gas; Air pressure is too high, can directly exit.

Existing cylinder pressure gage can only single-measurement automobile cylinder pressure.The tire pressure measurement meter also can only the single-measurement tire pressure, and structure is comparatively outmoded, and coarse ， And of scale and measurement unit are kilograms per centimeter ², do not meet national legal unit of measurement, more can not directly inflate and exit.

Problem in view of above-mentioned existence, the purpose of this utility model provides a kind of both energy measurements cylinder pressure, energy measurement tire pressure and brake-pipe pressure And and when recording tire pressure when too high or not enough again, the multi-functional measuring cell simple in structure, easy to use, with low cost that can in measuring process, directly exit and inflate, to improve serviceable life, economic benefit and the security of automobile, source of the gas can be used the pressurized air of automobile gas receiver, has improved the self-saving ability of automobile.

Above-mentioned task is realized by following measures: it adopts a metering body, and respectively with the cylinder pressure gauge head, tire pressure gauge head and brake piping are taken over and formed.

Compared with the prior art the utility model has the following advantages.

1, multi-functional.A tractor serves several purposes, energy measurement cylinder, tire and line pressure.

2, can be directly to inflation of tire or venting in measuring process.

3, source of inflation gas can be used the pressurized air of the gas receiver of automobile own, has improved the self-saving ability of automobile.

For the ease of understanding the utility model, attached structure principle chart illustrates that it has described multi-functional manometric principle of work.In the metering body A source of the gas is housed and takes over 1, bi-bit bi-pass guiding valve 2 triplate lines 3, tensimeter 4, pipe adapter 5 ， And connect cylinder pressure gauge head B respectively, include a retaining valve 6; Tire pressure gauge head C includes two retaining valve 7(7 '), top opening 8(8 ') and compound gasket 9(9 '); Measure pipeline pressure tap D.

The concrete course of work is as follows:

1, measure cylinder pressure: dress cylinder pressure gauge head B on joint 5, And aims at the dress spark-plug hole with gauge head and compresses, and then pressure gas enters metering body A by retaining valve 6 in the cylinder, and tensimeter 4 just can demonstrate cylinder pressure, surveys and finishes, and presses down guiding valve 2 venting.

2, measure tire pressure: dress tire pressure gauge head C on pipe adapter 5, when valve nozzle outside, aiming at valve nozzle with retaining valve 7 and top opening 8 compresses, at this moment, the valve nozzle end face is pressed on the compound gasket 9, top opening 8 backs down valve inside and retaining valve 7 simultaneously, and the compressed gas in the tire enters metering body A by retaining valve 7, just can read tire pressure from tensimeter 4.When valve nozzle inwards, then use 7 ', 8 ' this head.

3, bleed a tire: too high when recording tire pressure, slowly press down bi-bit bi-pass guiding valve 2, compressed gas is just emitted slowly by two position two-way valve 2 in the tire, reaches till the setting.

4, inflation of tire: when recording under-inflation, source of the gas is taken over 1 usefulness flexible pipe be connected with source of the gas, press down two position two-way valve 2, then high pressure gas is by two position two-way valve 2, the retaining valve 7(7 ' that is opened among the tire pressure gauge head C) and valve inside enter tire, reach till the setting.

5, measure brake-pipe pressure: dress is measured the end of pipeline pressure tap (head) D on joint 5, and the other end is connected on the brake piping, steps on master cylinder, and tensimeter just demonstrates tested line pressure.

Like this, give this multi-functional manometric task with regard to full the finishing in garden.
