Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1: for the utility model pressure peak chooses the schematic diagram with output unit automatically.
Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
As shown in Figure 1, the utility model provides a kind of pressure peak automatically to choose and output unit 100, this device 100 includes a pressure chamber 140, one end of pressure chamber 140 is sealedly connected with multiple pressure input 110, and the pressure supplying tube 120 between each pressure input 110 and pressure chamber 140 is provided with one-way valve 130; The other end of pressure chamber 140 is connected with pressure output end 150 and an equalizing orifice pipe 160.
Pressure chamber 140 is an airtight chamber, described airtight chamber is provided with the SEALING FITTING (not shown) for Bonding pressure input end 110, pressure output end 150 and equalizing orifice pipe 160.The concrete quantity of pressure input 110 is determined according to actual needs.One-way valve 130 controls fluid and can only unidirectionally flow in pressure chamber 140, each pressure supplying tube 120 is also respectively equipped with switch (not shown) and circulation display unit (not shown), in the present embodiment, described circulation display unit is flowmeter.Fluid flowing is cut off when switch on pressure supplying tube 120 cuts out; During switch opens, when the hydrodynamic pressure of pressure input 110 is greater than the pressure of pressure chamber 140 inside, it is inner that fluid flows to pressure chamber 140 from pressure input 110, and holding high office on showing device in pressure supplying tube 120 upper reaches to show circulation indicative mark, shows that now fluid is by one-way valve 130; When the pressure of pressure input 110 is less than the pressure of pressure chamber 140, fluid stops flowing automatically, and can not flow to pressure input 110 from pressure chamber 140, and now hold high office on showing device and can not show circulation indicative mark in pressure supplying tube 120 upper reaches.Equalizing orifice pipe 160 is provided with switch (not shown), before each measurement, open switch, equalizing orifice pipe 160 can make pressure chamber 140 communicate with air, make pressure chamber 140 measure initial pressure and equal atmospheric pressure, measure closing switch when starting, and then enclosed balance hole pipe 160.
From the above mentioned, a kind of pressure peak that the utility model provides is chosen and output unit 100 automatically, can once connect multiple pressure source, selects rapidly and automatically export maximum pressure value from multiple pressure source; By connection and the closedown of the switch control rule pressure source on pressure supplying tube 120, realize carrying out efficient pressure sequence to multiple pressure source; By utilizing the deixis of the switch control rule on pressure supplying tube 120 and the display unit that circulates, complete the pressure leveling to multiple pressure source; The delivery pressure each due to this device is pressure maximum, and when pressure source has slight fluctuations, the pressure of pressure chamber 140 inside is the maximum value of fluctuation, therefore stable output, can not be subject to fluctuation interference, realize the function to pressure source filtering.
It is such that the pressure peak that the utility model provides is chosen with the using process of output unit 100 automatically: before measurement, and connect instrumentation (instrumentation is special pressure measuring set, as micromanometer at pressure output end 150 place.Not shown in the drawings), open the switch on equalizing orifice pipe 160, pressure chamber 140 is communicated with air, makes pressure chamber 140 initial pressure be atmospheric pressure, then closing switch, and then enclosed balance hole pipe 160.Multiple pressure source (not shown) is connected one by one with pressure input 110, and opens the switch on pressure supplying tube 120 corresponding to each pressure source.Because pressure chamber 140 initial pressure is atmospheric pressure, the pressure source pressure that each pressure input 110 connects all is greater than pressure chamber 140 internal pressure, each pressure source fluid all can feed pressure chamber 140, and the circulation display unit on the pressure supplying tube 120 that each pressure source is corresponding all can show circulation indicative mark.Pressure in pressure chamber 140 reaches the minimum value in each pressure source at first, and the fluid of now corresponding pressure source stops circulation, and the circulation display unit on corresponding pressure supplying tube 120 no longer shows circulation indicative mark.By that analogy, each pressure source stops fluid circulation from small to large successively according to force value, and the circulation display unit on corresponding pressure supplying tube 120 no longer shows circulation indicative mark.Finally, pressure in pressure chamber 140 reaches the maximum value in each pressure source, instrumentation will demonstrate the force value in the pressure maximum source under steady state, thus realize the function automatically reading Pressure maximum value, because pressure supplying tube 120 is provided with circulation display unit, circulation indicative mark in circulation display unit on the pressure supplying tube 120 that pressure maximum source is corresponding is shown to finally, therefore pressure maximum source can be selected intuitively, above measuring phase can complete within very short time, and efficiency is very high.
After selecting pressure maximum source, close the switch on corresponding pressure supplying tube 120.Repeat above measuring phase, the maximum value in residual pressure source can be selected, by that analogy, the function all pressure sources being sorted by size, selects pressure minimum source can be realized.
When utilizing pressure peak of the present utility model automatically to choose to carry out pressure leveling with output unit 100, first carry out above-mentioned measurement operation and select pressure maximum source, and obtain the force value in pressure maximum source, keep the switch on the pressure supplying tube 120 of correspondence to be opening state.Then, from all the other pressure sources, select a pressure source as pressure source to be leveled, keep the switch on the pressure supplying tube 120 of correspondence to be opening state.Close the switch on pressure supplying tube 120 corresponding to other pressure sources.Then, slowly tune up the force value of pressure source to be leveled, adjustment process is continuous print, when force value just beyond pressure maximum source before this of the force value of pressure source to be leveled, circulation display unit display circulation indicative mark on pressure supplying tube 120, now the force value difference of two pressure sources is less, meets leveling requirement.By that analogy, the leveling that aforesaid operations can complete each pressure source is repeated.
From the above mentioned, a kind of pressure peak that the utility model provides is chosen and output unit 100 automatically, can once connect multiple pressure source, selects rapidly and automatically export maximum pressure value from multiple pressure source; By connection and the closedown of the switch control rule pressure source on pressure supplying tube 120, realize carrying out efficient pressure sequence to multiple pressure source; By utilizing the deixis of the switch control rule on pressure supplying tube 120 and the display unit that circulates, complete the pressure leveling to multiple pressure source; The delivery pressure each due to this device is pressure maximum, and when pressure source has slight fluctuations, the pressure of pressure chamber 140 inside is the maximum value of fluctuation, therefore stable output, can not be subject to fluctuation interference, realize the function to pressure source filtering.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
