Description
Technical field
The invention belongs to equipment line configurations field, be specifically related to a kind of in-line calibration calibration valve.
Background technology
The Pressure gauge of industrial use belongs to the compulsory verification project that national quality quality surveillance specifies, after Pressure gauge uses certain time, must flow through the measurement and calibration mechanism of qualification to carry out identifying calibration to it, to determine whether this Pressure gauge meets the accuracy of measurement of nominal.Need to removing from equipment pipeline during usual Pressure gauge assay calibration, the measurement and calibration mechanism being then delivered to qualification carries out identifying calibration, it is judged that whether it is qualified, is installed on equipment pipeline by Pressure gauge after assay calibration again.The Pressure gauge installed on some equipment directly communicates with high-pressure fluid, if dismounting manometer, whole equipment must be shut down in power-off, and impact produces, and causes damage, and assay calibration is extremely inconvenient.At present, generally adopt two or three stop valves and pipeline superposition to realize Pressure gauge and do not dismantle calibration, but be subject to the installing space of engineering equipment and relatively costly restriction, in practical application, also have a lot of problems to need to solve.
For above-mentioned prior art problem, the invention provides a kind of simple in construction, volume little, lightweight, the Pressure gauge in-line calibration calibration valve being easily installed and not easily reveal, can also arbitrarily regulate the size in Pressure gauge direction, damping adjusting hole simultaneously, solve the problems existed in prior art.
Summary of the invention
The present invention seeks to: a kind of Pressure gauge in-line calibration calibration valve is provided, have that volume is little, cost is low, simple in construction, Pressure gauge direction is adjustable, the feature such as easy to install, improves efficiency and the benefit of Pressure gauge assay calibration.
The technical scheme is that a kind of valve for the calibration of Pressure gauge in-line calibration, it includes: triple-valve body, needle, handwheel, locknut, excessive joint A, O, working line joint, calibration interface plug, excessive joint B；The straight-through end of two of described triple-valve body, the described excessive external Pressure gauge of joint B is passed through in one end, one end connects described calibration interface plug at ordinary times, the vertical end of described triple-valve body is connected on equipment working line by described excessive joint A, O, working line joint, and described needle is fixed by described locknut；During in-line calibration calibration, screw described handwheel, after making described needle and described triple-valve body combine closely, Bonding pressure table calibrating apparatus, according to Pressure gauge vertification regulation, Pressure gauge is carried out assay calibration；In-line calibration calibration is taken off described Pressure gauge calibrating apparatus, is connected described calibration interface plug, then unclamp described handwheel, make the normal display device working line pressure of Pressure gauge after terminating.
Further, described handwheel is connected on described triple-valve body by handwheel locknut.
Further, described handwheel is sealed by copper backing, O, phenyl tetrafluoride pad and described triple-valve body.
Further, described triple-valve body is lived female connection by working line interface with equipment working line, and described working line interface mother alive can arbitrarily rotate, and regulates Pressure gauge installation direction.
Further, described triple-valve body is lived female connection by pressure gauge connection with Pressure gauge, and described pressure gauge connection mother alive can arbitrarily rotate, and regulates Pressure gauge installation direction.
Further, described needle front end is the conical surface, rotates the openings of sizes between needle and described triple-valve body sealing surface described in described handwheel scalable.
The operation principle of the present invention is: normal condition lower valve is arranged on equipment working line, the working line of one end access device, a termination Pressure gauge, a termination calibration interface plug.Rotation hand wheel regulates needle and opens, and Pressure gauge is started working.According to gauge hand jitter conditions in equipment running process, rotation hand wheel suitably adjusts needle openings of sizes, and the openings of sizes of needle serves the effect of damping, makes Pressure gauge from high pressure temporary impact.Connect owing to one end of Pressure gauge on-line calibration valve is provided with the mother that lives, at valve axially can 360 ° of rotations, the installation Pressure gauge side of Pressure gauge in-line calibration calibration valve is also mother's connection of living, so Pressure gauge be perpendicular to valve body direction can also 360 ° of any rotations, arbitrarily rotating in both direction just can arbitrarily adjust manometric direction, in order to observed reading.When Pressure gauge to assay calibration cycle, only need testing person to rotate handwheel and close needle, pull down the plug cut-in pressure calibrator (-ter) unit of Pressure gauge on-line calibration valve side, operate according to " Pressure gauge vertification regulation ", the work of this manometric assay calibration within 1-2 minute, can be completed.After assay calibration completes, pull down calibrator (-ter) unit, again screw plug, open needle and can resume work.Whole assay calibration process is without device powers down, it is not necessary to dismounting Pressure gauge is to specialized agency's censorship.
The beneficial effects of the present invention is: this valve mechanism is simple, volume is little, cost is low, lightweight, it is easily installed, solving the Pressure gauge on engineering equipment needs device powers down and Pressure gauge to disassemble, report and submit the problem that professional institution's assay calibration work is numerous and diverse, improve manometric assay calibration efficiency and benefit；Any direction can be installed by Pressure gauge, it is simple to operator's observed reading；Scalable needle perforate size, reduces high-pressure fluid to manometric impact, extends manometric service life.
