Abstract
The utility model provides a pressure display unit of a super pure gas filling system. The pressure display unit comprises a pressure meter and a pressure transmitter, wherein the pressure meter and the pressure transmitter are respectively connected onto a gas filling pipeline. The pressure display unit has the advantages that after the structure is adopted, a mode of combining the pressure transmitter and the pressure meter is used, the system cleanliness is ensured, before the system is used, the detected pressure meter is used for checking the pressure transmitter, and the system reliability is improved. In the system production, only the clean pressure transmitter is used, and the polluted pressure meter cannot pollute the system.
Description
Technical field
The utility model relates to a kind of hyperpure gas charging system, particularly a kind of pressure-display unit of hyperpure gas charging system.
Background technique
Hyperpure gas is often referred to purity at the gas more than 99.9999%.In the bottled hyperpure gas production process, cylinder filling is the step of most critical.If cylinder filling is careless slightly, will cause the very big fluctuation of gas purity.High-purity gas is filled with two class methods, and the first kind is that bottle is filled in pressurization behind the low pressure purifying; Second type is directly to fill bottle behind the high pressure purifying.First kind method is many to be use in 99.999% o'clock filling purity gases.Because diaphragm type compressor possibly cause the clean gas secondary pollution, the modes that fill behind the high pressure purifying that adopt when filling hyperpure gas more.
Usually can use pressure gauge in the existing hyperpure gas charging system.The national regulation pressure gauge needs regularly to detect.Because the detected pressures table can use the hydrostatic test, the pressure gauge after all detect can cause serious pollution to charging system.And because the pressure gauge dead volume is big and moisture is difficult to displacement, so manometric regular detection has also produced great influence to the hyperpure gas charging system.Some system can the working pressure transmitter.Though pressure transmitter does not have the regulation of compulsory test, do not detect and have potential safety hazard, detection heel pressure gauge is identical also can be polluted.
The model utility content
The utility model proposes a kind of pressure-display unit of hyperpure gas charging system, and it can overcome deficiency of the prior art effectively, and the mode that working pressure transmitter and pressure gauge combine has guaranteed the cleanliness of system, has increased the reliability of system.
The technological scheme of the utility model is achieved in that a kind of pressure-display unit of hyperpure gas charging system, comprises pressure gauge and pressure transmitter, and said pressure gauge and pressure transmitter are connected on the gas filling pipeline.
As preferably, said pressure gauge and pressure transmitter are connected on the gas filling pipeline through two ends of three-way pipeline.
As preferably, also be connected with pressure meter valve and pressure gauge outlet valve on the said manometric connecting pipeline.
As preferably, also comprise the safety valve that is connected in parallel with the pressure transmitter two-way.
The beneficial effect of the utility model is: after adopting said structure, the mode that working pressure transmitter and pressure gauge combine guarantees system's cleanliness, before system uses, uses the pressure meter calibration pressure transmitter that has detected, increases system reliability.During system produces, only use clean pressure transmitter, the pressure gauge of pollution can contaminated system.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is one of them embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is one of them embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1; A kind of pressure-display unit of hyperpure gas charging system; Comprise pressure gauge 1 and pressure transmitter 2; Said pressure gauge 1 is connected on the gas filling pipeline 3 with two ends of pressure transmitter 2 through three-way pipeline, also is connected with pressure meter valve 4 and pressure gauge outlet valve 5 on the connecting pipeline of said pressure gauge 1.Also comprise the safety valve 6 that is connected in parallel with pressure transmitter 2 two-ways in the said pressure-display unit.
When operation, open the high pressure purifying machine in the hyperpure gas charging system, make it to reach operating temperature; Open diaphragm type compressor; Whether open pressure meter valve 4 backs and open suction valve 7, it is consistent with pressure transmitter 2 readings to observe pressure gauge 1.If reading is inconsistent, then shutdown inspection pressure gauge 1 and pressure transmitter 2.If reading is consistent, then closing pressure table valve 4 and suction valve 7 are accomplished pressure transmitter 2 verifications; Open atmospheric valve subsequently and close after 8,5 seconds, discharge conduit pressure.Promptly before system uses, used pressure gauge 1 verification that detected pressure inverting, 2; In system produces, only use clean pressure transmitter 2, the pressure gauge 1 of pollution can contaminated system.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
