Abstract
The invention provides a pneumatic spring meter clamping device of a check and verification device for diaphragm gas meters. The pneumatic spring meter clamping device mainly comprises double-shaft cylinders, gas meter support plates and pressure regulating and reducing valves. The working principle is that gas with pressure greatly lower than the normal working pressure is produced through the pressure regulating and reducing valves, the cylinders produce push force slightly larger than the gravity of the gas meters, the support plates and the cylinder parts by means of the gas, so that an operator can press the support plates by the handheld gas meters slightly to place the gas meters to preset positions and then loosen the gas meters, and the gas meters are clamped by the push force of the cylinders. Gas circuit changeover valves are rotated to introduce the gas with normal working pressure into the cylinder so as to clamp the gas meters. The pneumatic spring meter clamping device has the main advantages as follows: 1, the working efficiency is higher than a common meter clamping device, and the mounting time of a single gas meter can be shortened; 2, safety production is better facilitated. The meter clamping gas pressure is greatly smaller than the normal working pressure, so that harm is avoided even though fingers of the operator are clamped in a meter clamping process.
Description
Art
The invention belongs to diaphragm gas meter calibra tion inspection technology field, relate to a kind of equipment in order to calibrating, inspection gas meter, flow meter, this equipment is made up of standard, source of the gas, control system, data handling system and tong-test ammeter device, and this invents the tong-test ammeter device namely belonged in this equipment.
Background technology
Diaphragm gas meter is exactly usually the gas meter used in our family.The accuracy of gas meter, flow meter is most important index in energy measurement.The assay calibration of so-called gas meter, flow meter, the indicating value of standard measuring device higher with accuracy exactly compares, and generally represents with the percentage error of the maximal value of correspondence.
Due to gas meter, flow meter enormous amount, the mode mostly adopting multiple stage to connect during calibrating inspection is to raise the efficiency, and the number of units of series connection is generally 4 ~ 12.The installation of gas meter, flow meter on calibrating verifying attachment mainly adopts and pneumaticly clamps mode.Fig. 1 knownly pneumaticly clamps mode.Clamping of each gas meter, flow meter is controlled by two five-way valves 7.
Summary of the invention
Pressure regulation reduction valve is utilized to produce the gas being significantly smaller than service pressure, cylinder is made to produce thrust slightly larger than gas meter, flow meter and supporting plate and cylinder part gravity with this gas, gas meter, flow meter just can be placed into preposition by pressing palette with hand-held gas meter, flow meter by such operating personnel gently, then unclamp gas meter, flow meter, rely on the thrust of cylinder to be clamped by gas meter, flow meter.The gas of service pressure is passed into cylinder and gas meter, flow meter can be clamped by rotation air way switch valve.
Main composition has twin shaft cylinder, gas meter, flow meter supporting plate and pressure regulation reduction valve
Embodiment
Example of the present invention is made up of the individual parts in Fig. 2.
1, train wheel bridge
2, gas meter, flow meter connection
3, gas meter, flow meter
4, tong-test ammeter supporting plate
5, cylinder axis
6, cylinder venthole sound suppressor
7, twin shaft cylinder
8, exhaust switch valve
9, gas-holder
10, normal pressure air inlet switch valve
11, pressure regulation reduction valve air inlet switch valve

During demolition diaphragm gas meter, duty is as Fig. 2, and exhaust switch valve 8 is opened, and normal pressure air inlet switch valve 10, pressure regulation reduction valve air inlet switch valve 11 are closed, and the piston of twin shaft cylinder and tong-test ammeter supporting plate and gas meter, flow meter drop to bottom dead centre by Action of Gravity Field.Now gas meter, flow meter is in free state, and gas meter, flow meter can be removed by operating personnel.
Install before gas meter, flow meter time duty as Fig. 5, exhaust switch valve 8 is closed, and normal pressure air inlet switch valve 10 cuts out, pressure regulation reduction valve air inlet switch valve 11 is opened, and piston and the tong-test ammeter supporting plate of twin shaft cylinder rise to upper dead center under the effect of low-pressure gas.This timer does not have gas meter, flow meter, and gas meter, flow meter can be installed on device by platform by operating personnel.
Install in gas meter, flow meter time duty as Fig. 4, exhaust switch valve 8 is closed, normal pressure air inlet switch valve 10 cuts out, pressure regulation reduction valve air inlet switch valve 11 is opened, and piston and the tong-test ammeter supporting plate of the right two epi-position twin shaft cylinder rise to upper dead center under the effect of low-pressure gas.Existing two gas meter, flow meters on this timer, remaining gas meter, flow meter can be installed on device by platform by operating personnel.
Install after gas meter, flow meter time duty as Fig. 3, exhaust switch valve 8 is closed, normal pressure air inlet switch valve 10 is opened, pressure regulation reduction valve air inlet switch valve 11 cuts out, and now mounted four gas meter, flow meters hold out against by the piston of twin shaft cylinder and tong-test ammeter supporting plate under the effect of atmosphere gas., operating personnel can start to carry out examining and determine or inspection work.
