Embodiment
As shown in Figure 1, the utility model portable apparatus stopple coupon purges verifying attachment and comprises Inlet ball valve 1, filtrator 2, reduction valve 3, inlet pressure table 4, two vent ball valves 5 and two delivery gauges 6, described Inlet ball valve 1, filtrator 2 are connected by pipeline successively with reduction valve 3, described two vent ball valves 5 are parallel to the output terminal of described reduction valve 3 by pipeline, the output terminal of described reduction valve 3 is located at by described inlet pressure table 4, and described two delivery gauges 6 are located at the output terminal of described two vent ball valves 5 respectively.
Further, as shown in Figure 2, this device also comprises casing 7, described Inlet ball valve 1, filtrator 2, reduction valve 3, inlet pressure table 4, two vent ball valves 5 and two delivery gauges 6 are located in described casing 7 respectively, described Inlet ball valve 1 input end is positioned at described casing 7 side, and the output terminal of described two vent ball valves 5 is positioned at the opposite side of described casing 7.
Each component integration is arranged in casing by this device, is easy to carry, and facilitates the purging inspection operation of production scene instrument stopple coupon; Source of the gas enters from Inlet ball valve, sends to reduction valve.Can purge instrument both sides stopple coupon simultaneously, filtrator can filter the dirt in source of the gas, reduction valve controls the size purging compressed air pressure, inlet pressure table detects compressed air pressure, two delivery gauges detect two-way sweep air pressure respectively, and two vent ball valves are used for shut-down purge air.Two vent ball valves and two delivery gauges cooperations can detect stopple coupon and purge front and after purging overpressure, also can confirm whether leave overbottom pressure in stopple coupon after purging, confirm that whether stopple coupon is unimpeded with this.And by the pressure of adjustment reduction valve, control the air pressure of two-way outlet, check the quality of transmitter.
Purge in operation in tradition, the pressurized air of use is not instrument air but uses mixedly air, and its internal moisture diffusion is comparatively large, easily causes sampling line ponding, makes the pressurized air blown out often with a large amount of steam.Filtrator is set in this device, ensure that the pressurized air entering instrument stopple coupon does not have steam, tube wall ponding can not be caused, adsorption of dust; Damage can not be caused to the instrument in device, ensure that manometric use safety.When general, the pressure of purging air, without particular/special requirement, generally believes that pressure is the bigger the better, but has Subsampling pipe and non-required reaches purging maximum pressure at once, as gaspipe line.Normally used air pressure of using mixedly is all higher, but need to ensure that scavenging pipeline maintains a barotropic state before purging, purge in connecting system more subsequently, therefore sweep air pressure is controlled by reduction valve, a slight positive pressure state is maintained before instrument stopple coupon is purged, can not make gas overflowing in stopple coupon, controlling appropriate pressure can purge when guarantee does not cause instrument to damage.Pressure detection is also the important ring purged simultaneously, in traditional purging operation, uncontrollable and detection enters the sweep air pressure of stopple coupon, also cannot contrasting sampling overpressure purging the change between front and back, being more difficult to the size, the pipeline degree of mobility that judge back pressure; Therefore this device arranges a precision pressure gauge at reduction valve output terminal, can observe purging bleed pressure, and appropriate controlled pressure contributes to guarantee equipment and do not broken by pressure-air; Two vent ball valves judge original pressure in stopple coupon by two delivery gauges after connecting stopple coupons, and the change of reduced pressure after purging, thus judge whether stopple coupon is improved after purging.Suddenly close a vent ball valve during purging, make pressure remain in stopple coupon, observe the speed of pressure drop, easily can judge the degree of mobility of stopple coupon.Select the tensimeter that positive/negative-pressure can use in this device, in the work of various distinct device, can use.
This device is also applicable to the inspection of transmitter class instrument, and first this device is doubleway output, and the output on each road has accurate delivery gauge to carry out control and vent ball valve can switch gas circuit, and reduction valve can control pressure in gas circuit.Subsequently, only need open the vent ball valve of required output pressure, use reduction valve to adjust to required pressure, after closing this vent ball valve, the pressure of transmitter inside is just by wherein locked; Open another road ball valve afterwards, the required pressure of same output, defines the environment of a differential pressure for transmitter, and whether the output can simulating actual condition inspection transmitter is qualified.
