Description
Technical field
The present invention relates to the flame snuffer production field, relate in particular to a kind of cylinder body of fire extinguisher pressure-resistant stopping property gas and survey all-in-one and pressure-resistant stopping property method of testing.
Background technology
Cylinder body of fire extinguisher is a kind of high pressure vessel, must carry out water pressure test for strength according to GB GB4351 standard when selling at home, and namely water carries out impermeability test to cylinder body of fire extinguisher.
Number be 2011101500491 in Chinese patent application, date of publication be January 18 in 2912 day, be called in the patent document of " a kind of CO2 flame snuffer gas cylinder free style hydraulic pressure test equipment " and disclose a kind of equipment with the hydraulic pressure test cylinder body of fire extinguisher.This equipment comprises frame, is rotatably connected on the flame snuffer sleeve barrel fixing device that is provided with flow passage and the pressure generating equipment that is connected with flow passage (hydraulic pump) on the frame, in cylinder body of fire extinguisher, be fixed on the flame snuffer sleeve barrel fixing device behind the injected water during test, then keep the setting duration after hydraulic pressure in the cylinder body of fire extinguisher being increased to reach the resistance test value by pressure generating equipment, observe cylinder body of fire extinguisher whether explosion distortion or produce leak.
But according to the EN3-8 of European Union standard code, need to test through 100% pressure intensity cylinder body of fire extinguisher be resistance to pressure test and performing leak test, guaranteeing that each cylinder body of fire extinguisher does not leak and meets requirement of withstand voltage, but to what medium carrying out withstand voltage with and sealing test does not require.Flame snuffer manufacturer all separately carries out these two tests at present, namely first in the packoff that is provided with the cylinder body of fire extinguisher stationary installation, fix cylinder body of fire extinguisher by the cylinder body of fire extinguisher stationary installation in the packoff, then carry out the resistance to pressure test to cylinder body of fire extinguisher input gases at high pressure, after after voltage-withstand test is finished gases at high pressure all being bled off cylinder body of fire extinguisher is taken off, the cylinder body of fire extinguisher that voltage-withstand test is qualified moves on to hydraulic pressure test equipment again, by the cylinder body of fire extinguisher stationary installation that is arranged on the hydraulic pressure test equipment cylinder body of fire extinguisher is fixed, the water that input is pressurizeed to cylinder body of fire extinguisher carries out performing leak test.
So the existing method that cylinder body of fire extinguisher is carried out the pressure-resistant seal property testing that satisfies the EN3-8 of European Union standard code has the following disadvantages: voltage-withstand test is separately carried out at different devices with sealing test, cause the cylinder body of fire extinguisher cost of manufacture high, test process is loaded down with trivial details wastes time and energy; All emptying of Hi-pot test gas behind the durability test causes very large energy dissipation (will detect gas boosting and need to expend the energy to high pressure); Water carries out the waste that performing leak test can cause water resource.
Summary of the invention
The invention provides the disposable cylinder body of fire extinguisher pressure-resistant stopping property gas of finishing cylinder body of fire extinguisher resistance to pressure and performing leak test of a kind of energy and survey all-in-one and pressure-resistant stopping property method of testing, solved to the resistance to pressure of cylinder body of fire extinguisher and performing leak test by different devices and different pressuring methods test existing waste resource, operation loaded down with trivial details, waste time and energy, problem that cost of manufacture rises.
Above technical matters solves by following technical proposal: a kind of cylinder body of fire extinguisher pressure-resistant stopping property gas is surveyed all-in-one, comprise the cylinder body of fire extinguisher stationary installation that is provided with inlet channel, detect gas return path and frame, but described frame is provided with the explosion-proof chamber of the carrying liquid of door opening and is used for the explosion door of the described door opening of shutoff, be provided with some described cylinder body of fire extinguisher stationary installations in the described explosion-proof chamber, described detection gas return path comprises gas admittance valve, blowdown valve and vent valve, the gas outlet of described gas admittance valve, the air intake opening three of the air intake opening of vent valve and blowdown valve is connected with described inlet channel.During use in explosion-proof chamber injected water, the import of air pump with gas admittance valve is connected, fix on the mouth of flame snuffer sleeve and with the flame snuffer sleeve is unsettled by the shutoff of cylinder body of fire extinguisher stationary installation, cover explosion door, open gas admittance valve, air pump is inflated in the cylinder body of fire extinguisher and cuts out gas admittance valve after air pressure reaches the durability test value, keep this pressure and after setting duration, open blowdown valve so that the air pressure in the cylinder body of fire extinguisher is reduced to the performing leak test value, close blowdown valve and make the cylinder body of fire extinguisher whether leakage phenomenon of observing under water; Opening at last vent valve all bleeds off the gas in the cylinder body of fire extinguisher.Namely finished the pressure-resistant seal property testing.Cylinder body of fire extinguisher can soak or not be immersed in the water when carrying out the resistance to pressure test.
As preferably, the exhausr port of described blowdown valve is docking together with gas-holder.Blowdown valve makes the gases at high pressure of discharging can be collected together for other pneumatic compression devices utilization good energy-conserving effect.
As preferably, the exhausr port of described vent valve is provided with exhaust box.The noise that produces in the time of reducing the interior gas of emptying cylinder body of fire extinguisher, environment protecting is good.
The present invention also comprises control module, and described gas admittance valve, blowdown valve and vent valve all are motorized valve and are electrically connected with control module.The action of gas admittance valve, pressure limiting valve and vent valve is controlled by control module.Automaticity is good, and accuracy is good, and detection efficiency is high, and is more in addition time saving and energy saving.
As preferably, described explosion-proof chamber has two, all be provided with described cylinder body of fire extinguisher stationary installation in two explosion-proof chambers, described detection gas return path has two, two are detected gas return path and are connected with the cylinder body of fire extinguisher stationary installation in two explosion-proof chambers respectively, two explosion-proof chambers share an explosion door, described frame is provided with the explosion door position and switches topworks, and control device is controlled only has a gas admittance valve that detects in the gas return path can open and switch by the explosion door position on the door opening of the explosion-proof chamber that topworks is located at the explosion door automatic cover to carry out the resistance to pressure test in the same time.Realized that at one time an interior explosion-proof chamber is carrying out that durability test makes, can carry out performing leak test or change workpiece work in another explosion-proof chamber.Share explosion door, compact conformation, explosion door different work personnel's operation produces to be interfered; Automaticity is good, and security is good.Can improve operating personnel's utilization factor.
As preferably, it is cylinder that topworks is switched in described explosion door position.Simple for structure.
