Description
Technical field
The utility model relates to it is a kind of can calibrated in situ elastic element formula Novel pressure meter.
Background technique
Elastic element formula pressure gauge is using very extensive measurement instrument in pressure measurement, up to now, both at home and abroad respectively
The elastic element formula pressure gauge (hereinafter referred to as pressure gauge) itself that class equipment generally uses not can be carried out calibrated in situ, dismantle
Carrying out offline measurement verification or calibration afterwards, not only working efficiency is low, does not adapt to pressure gauge using the reality having a large capacity and a wide range, and
And dismantle and return dress and be easy to cause the damage that the pressure gauge connection of pressure gauge itself and its equipment is safe and reliably seals in the process,
The standby use of dress (setting) is influenced, furthermore pressure gauge dismounting requires to stop the standby normal operation of dress (setting), causes production cost
Increase, on the other hand, equips the pipeline at pressure measurement position since the requirement in design or space etc. cannot additionally mounted special use
In the special purpose interface of pressure gauge on-line metering calibration, therefore, pressure gauge, which can not achieve calibrated in situ, becomes restriction equipment metering skill
The important bottleneck of art service.
Utility model content
The purpose of the utility model is to provide a kind of structures simply, does not increase current phenotype volume, and calibration efficiency is high, economical
Property good, environment-adapting ability it is strong can calibrated in situ elastic element formula Novel pressure meter.
The utility model technical solution used for the above purpose is: it is a kind of can calibrated in situ elastic element formula
Novel pressure meter, including pressure gauge outfit, valve body, Rotatable tee joint ball valve, calibrated channel and medium isolating device, the pressure gauge
Head is mounted on valve body, and pressure gauge outfit is structure as a whole with valve body, and the side of the valve body is equipped with calibration source interface, described to revolve
Turn three-way ball valve to be mounted in valve body, calibrated channel setting in calibration source interface, one end of calibrated channel with it is rotatable
Three-way ball valve connection.
Anti-leak warning sealing cover is installed on the calibration source interface.
The top of the anti-leak warning sealing cover uses the elastic metal cap of slim indent.
When calibration, Rotatable tee joint ball valve is rotated, is connected to the interconnection of Rotatable tee joint ball valve with calibrated channel, school
Quasi- channel is connected to by calibrating source interface with calibration source, while it is logical to cut off the longitudinal direction that Rotatable tee joint ball valve is connected to pressure gauge outfit
Road.
The utility model one kind can calibrated in situ elastic element formula Novel pressure meter, structure is simple, does not increase current table
Type volume, calibration efficiency is high, safe and reliable, good economy performance, environment-adapting ability are strong, is suitable for the features such as popularization；With conventional pressure table
It compares, can more easily and efficiently realize calibrated in situ, reduce damage of the instrument disassembly to equipment to the maximum extent, to greatest extent
The integrity and reliability of ground Support Equipment.
Detailed description of the invention
Fig. 1 be the utility model one kind can calibrated in situ elastic element formula Novel pressure meter structural schematic diagram.
In figure: 1, pressure gauge outfit；2, valve body；3, Rotatable tee joint ball valve；4, calibrated channel；5, medium isolating device；6,
Anti-leak warns sealing cover；7, source interface is calibrated.
Specific embodiment
As shown in Figure 1, can calibrated in situ elastic element formula Novel pressure meter, including it is pressure gauge outfit 1, valve body 2, rotatable
Three-way ball valve 3, calibrated channel 4 and medium isolating device 5, pressure gauge outfit 1 are mounted on valve body 2, and pressure gauge outfit 1 is with valve body 2
Integral structure, the side of valve body 2 are equipped with calibration source interface 7, and Rotatable tee joint ball valve 3 is mounted in valve body 2, and calibrated channel 4 is set
It sets at calibration source interface 7, one end of calibrated channel 4 is connect with Rotatable tee joint ball valve 3, is equipped on calibration source interface 7 anti-
Leakage warning sealing cover 6 when calibration, opens anti-leak and warns sealing cover 6, rotate Rotatable tee joint ball valve 3, make Rotatable tee joint
The interconnection of ball valve 3 is connected to calibrated channel, and calibrated channel 4 is connected to by calibrating source interface 7 with calibration source, while cutting off can
The vertical passage that swivel tee ball valve 3 is connected to pressure gauge outfit 1, between the different medium in calibration source and pressure gauge effectively every
From preventing the pollution of the standby working media of dress (setting), anti-leak warns sealing cover 6 as the safety measure for calibrating source interface, this is close
Capping top using slim indent elastic metallic cover plate, elastic stress size depending on pressure medium and pressure value are different,
The sealing cover protrusion that indent is found in use or when calibrating indicates that the sealing of ball valve position is more than defined threshold, needs to take safety
Measure, can the elastic element formula Novel pressure meter of calibrated in situ realize that measuring mechanism is being pressed by the conversion of Rotatable tee joint ball valve
Switching between power calibrating installation and the standby testing pressure source of dress (setting), provides peace for the real time calibration and period regulation of pressure gauge
Complete convenient and fast channel improves the working efficiency of pressure gauge without dismantling pressure gauge because of calibration again to greatest extent, and design can be former
Position calibration pressure gauge, it is important to pressure gauge installation threaded base and table body inside elastic element junction install additional it is a set of can
The Rotatable tee joint ball valve 3 for facilitating the T-shape channel of conversion makes three mutual connection in orthogonal channel, passes through Rotatable tee joint
The convenient cutting Article 3 channel interface of ball valve rotation needs to examine as long as ending calibrated channel when pressure gauge works normally
When fixed or calibration, Rotatable tee joint ball valve is rotated, the calibrated channel for connecting calibration source interface ends working hole simultaneously, i.e., rotatable
Calibrating installation is connected on the calibrated channel of calibration source interface by the vertical passage that three-way ball valve is connected to pressure gauge outfit, according to
Defined method can be completed, and since calibrated channel design has medium isolating device, will not make to calibrate medium and measured work
Medium is blended to produce to standby damage is installed, and rotation Rotatable tee joint ball valve makes working interface connection can be extensive after the completion of calibration
Multiple normal operating conditions, whole process is easy to operate, without the normal operation for stopping equipment.
