But the manometric calibration work of the type minor diameter can not be completed high-efficiency high-quality, high temperature calibration can not be completed simultaneously, and the special calibration joint of the monolithic that pressure sensor need not be dismantled.
Utility model content
External genuine calibration can only be beamed back at present in order to overcome minor diameter pressure gauge, and sensor can only be pulled down carry out calibration, this two large problems of overall calibration cannot be carried out.
The utility model provides the manometric calibration of a kind of CalScan minor diameter needs one can complete high temperature calibration, need not dismantle again the special calibration joint of monolithic of pressure sensor, complete the manometric calibration work of the type minor diameter for high-efficiency high-quality.
The technical solution of the utility model is:
The overall calibration special joint of a kind of CalScan minor diameter pressure gauge, comprise mark packing element, described mark packing element is hollow cylinder, the upper seal of described mark packing element is connected with seal pressure cap, described seal pressure cap and hollow mark packing element form a confined space, described seal pressure cap is provided with jack, and described jack is communicated with mark packing element inside; The below of described mark packing element is sealedly connected with lower contact.
Described seal pressure cap is provided with external screw thread, and external screw thread is tightly connected with mark packing element.
Described mark packing element is connected by sealing ring with lower contact.
Described a kind of CalScan minor diameter pressure gauge overall calibration special joint length is 24-26cm.
The external diameter of described mark packing element (2) is 50-56mm, and internal diameter is not less than 20mm.
Described a kind of CalScan minor diameter pressure gauge overall calibration special joint operating temperature 0 DEG C ~+200 DEG C; Pressure-bearing is greater than 137MPa.
the beneficial effects of the utility model are:
The utility model by mark packing element, seal pressure cap and minor diameter pressure gauge tripartite with the use of, for minor diameter pressure gauge provides airtight pressure-bearing environment; Leave jack in seal pressure cap internal thread in the utility model, pluggable data wire realizes real-time data acquisition.Through simple maintenance, the utility model is reusable.Not only solving minor diameter pressure gauge cannot the problem of calibration outside genuine, achieve the manometric overall calibration of minor diameter simultaneously, do not need to dismantle minor diameter pressure gauge again, save censorship and the time and efforts needed for dismounting, greatly save the expense of carrying out needed for calibration to minor diameter pressure gauge simultaneously.
