Description
Technical field
The present invention relates to field of instrumentation technology, be specifically related to a kind of journey table adjustment system that connects.
Background technology
Tradition connects the adjustment of journey table and carries out on one way adjustment platform, need first the table for the treatment of adjustment to be installed on positive source of the gas and tested, after having tested, pull down to be again installed to angrily and test on source, and in the adjustment process of Lian Chengbiao, because malleation and negative pressure are carried out simultaneously on an adjustment platform, for constantly conversion of standard scale, from being just transferred to accurate adjustment, need to repeatedly change, so standard scale wants constantly upper and lower.Table of adjustment, replacing can reach left and right 5 times, makes labour intensity large, and collating time is long.
The deficiencies in the prior art are: tradition connects the adjustment of journey table, compared with malleation and negative pressure, all carry out separately respectively, and all on an adjustment platform, carry out, table to be measured will be surveyed respectively negative pressure and malleation, malleation standard scale and negative pressure standard scale will synchronously switch simultaneously, table of adjustment, and replacing can reach left and right 5 times, make labour intensity large, collating time is long.
Summary of the invention
The object of the present invention is to provide a kind of company's journey table adjustment system that can carry out malleation and negative pressure test on same adjustment platform.
For achieving the above object, technical scheme of the present invention is as follows: a kind of journey table adjustment system that connects, comprise the first reversal valve, the second reversal valve, gas admittance valve and air release, described the first reversal valve has two gas source inlets and a source of the gas outlet, described the second reversal valve has a gas source inlet and two source of the gas outlets, two gas source inlets of described the first reversal valve connect respectively positive source of the gas and the source of doing something in a fit of pique, described gas admittance valve air intake opening is connected with the source of the gas outlet of the first reversal valve, this gas admittance valve gas outlet is connected with air release by pipeline, on pipeline between gas admittance valve gas outlet and air release, be provided with meter connector to be measured, this gas admittance valve gas outlet is connected with the gas source inlet of the second reversal valve by pipeline, two source of the gas outlets of this second reversal valve are connected with respectively malleation standard scale and negative pressure standard scale.
Adopt said system, when showing, table to be measured is connected on meter connector to be measured, if compared with malleation, open gas admittance valve, the first reversal valve is switched to positive source of the gas, the second reversal valve switches to malleation standard scale and is communicated with, and then shows; If compared with negative pressure, open gas admittance valve, the first reversal valve is switched to angrily source, the second reversal valve switches to negative pressure standard scale and is communicated with, and then shows; Air release between switching for both is emitted the gas in pipeline, and this system is shown conveniently, to be convenient to the switching of malleation and negative pressure, and need not be malleation standard scale or negative pressure standard scale more repeatedly load onto or pull down, save labour, greatly improved and shown efficiency simultaneously.
One of them gas source inlet of the first reversal valve is connected with vacuum pump, and the motor of this vacuum pump accesses power supply after connecting with electric switch.
Vacuum pump is for the manufacture of source angrily, and positive source of the gas can be with manufactures such as air compressor machines.
Described the first reversal valve, the second reversal valve are hand-operated direction valve, and described electric switch is hand switch; The handle of described the first reversal valve, the second reversal valve and electric switch is connected by same trace, and when compared with malleation, described the first reversal valve is connected positive source of the gas, and the second reversal valve is connected malleation standard scale, and described electric switch disconnects; When compared with negative pressure, described the first reversal valve is connected angrily source, and the second reversal valve is connected negative pressure standard scale, and described electric switch is closed.
Adopt said structure, the handle of the first reversal valve, the second reversal valve and electric switch is connected by same trace, when malleation and negative pressure switching, can only by a trace, operate, settle at one go, easy to operate quick, the first reversal valve wherein and the second reversal valve can be replaced with five position three-way valves.
The invention has the beneficial effects as follows: when adjustment connects journey, reduce the replacing number of times of standard scale, the adjustment number of occurrence is reduced, clearly show deviation, can improve 50% efficiency, reduce labour intensity, enhance productivity, more convenient operation, whole adjustment and round of visits significantly shorten, tensimeter effect for adjustment density meter type is particularly evident, low cost of manufacture, long service life, little power consumption.
