Description
Technical field
The utility model belongs to tensimeter detection technique field, is specifically related to a kind of Pneumatic pressure table calibration equipment.
Background technology
In chemical process, partial pressure table is often used for the gas medium detecting special physicochemical characteristic, portion gas medium requirements can not contact with water, oily substance, in case class gas medium chemical reaction occurs and causes industrial accident after contacting with water or oily substance here.And for detecting the tensimeter of this type of gas medium, traditional piston type pressure gauge checking table method of calibration inevitably makes to produce the residual of oily substance in tensimeter., there is the shortcomings such as complex structure, air feed source of the gas are impure, gaseous tension is not high enough, installation and application is loaded down with trivial details, the request for utilization of certain customers can not be met in some gas type pressure calibrations in addition.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art and provides a kind of Pneumatic pressure table calibration equipment, and this apparatus structure gas that is simple, that meet the special physicochemical characteristic of part is comparatively strict with pressure meter calibration.
In order to achieve the above object, the utility model adopts following technical scheme:
The utility model provides a kind of Pneumatic pressure table calibration equipment, comprises High Purity Nitrogen source of the gas, septum valve, system standard tensimeter, testing pressure table incoming end and pressure meter calibration stand; Described pressure meter calibration stand is by base, verification panel and form through three branch roads that verification panel is uniform, and Article 1 branch road is connected with system standard tensimeter by ball check valve I, and Article 2 branch road is connected with blowdown valve; Article 3 branch road is connected with testing pressure table incoming end by ball check valve II; The gas of described High Purity Nitrogen source of the gas is communicated with three branch roads respectively by main line, and main line is provided with septum valve.
Described main line and three branch roads are stainless-steel tube, and stainless-steel tube is withstand voltage, and scope is 0 ~ 50MPa; The withstand voltage scope of described septum valve is 0 ~ 50MPa.
The purity of described High Purity Nitrogen source of the gas is at least 99.999%.
Compared with prior art, the beneficial effect that obtains of the utility model:
1. have employed High Purity Nitrogen source of the gas in the utility model structure, because its purity is high, free from foreign meter, do not remain, to avoid in tensimeter residue with survey medium generation chemical reaction.
2. the utility model adopts high-pressure pressure regulating valve, realizes the pressure regulation of gas source feed end, pressurize object, especially when micro-air pressure adjustment, possesses very strong operability.
3. the utility model device solves in chemical industry actual production process, traditional oils pressure type pressure meter calibration stand can not need be used to verify manometric problem to part, avoid this type of tensimeter contacting hydrous or after oil based media, or cause the residuary water in tensimeter or oily substance measuring contamination medium and measuring media generation chemical reaction cause the generation of device damage or security incident.
