The utility model discloses a valve leakage detection special device which comprises a frame which is provided with a screw rod. The top of the screw rod is provided with a tray. Two sides of the tray are provided with baffles. One side of each of the baffles facing the tray is provided with a sealing pad. The baffles and the sealing pad are provided with holes. The baffles are fixed with baffle spiral screws. The baffles at two sides are respectively connected with an air inlet pipe and an air outlet pipe. The air inlet pipe is orderly provided with an adjusting valve, an exhaust valve, an inlet valve and a pressure gauge between an air inlet port and a baffle. The air outlet pipe is orderly provided with an alarm protection electromagnetic valve, a pressure gauge and an exhaust valve between a baffle and an air outlet port. The frame is internally provided with a liquid spraying pot. A liquid spraying pot inlet pipe is arranged between the liquid spraying pot and the air inlet port of the air inlet pipe, and the liquid spraying pot inlet pipe is provided with a leakage detection liquid inlet valve. The liquid spraying pot is communicated with the outside and is provided with a liquid spraying pot exhaust pipe. The pressure gauge on the air outlet pipe is connected with an alarm device. The valve leakage detection special device is used for detecting whether a valve has leakage or not and has the advantages of high accuracy, simple operation and high safety.
Description
Technical field
The utility model relates to a kind of leakage detection apparatus of chemical fibre pipeline valve, especially a kind of melt pipe valve leak detection isolated plant.
Background technology
In the fused mass directly spinning installation process, because valve all welds, valves leakage, leaking outside causes in the leak detection process being difficult to pressurize, often by sealing the pressurize leak detection after valve is cut off again, and the fused mass directly spinning pipeline is more, valve also is difficult to determine to be which valve is leaking more a period of time, has caused like this taking a lot of work, the time-consuming material that takes again.So designed valve and hunt leak, guarantee that the valve that welds is good for fear of the generation of this class phenomenon before welding, this valve leak detection dedicated trolley is easy and simple to handle, is regardless of valve size, and valves leakage has the alarm device, and the saving of labor saves time again.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, and a kind of valve effective valve leak detection isolated plant to leaking in the valve inspection, leaking outside before welding is provided.
In order to achieve the above object, a kind of valve leak detection isolated plant that the utility model is designed, it comprises frame, and described frame is provided with screw mandrel, and the screw mandrel top is provided with pallet; Described pallet both sides are provided with baffle plate, and the one side over against pallet on the baffle plate is provided with sealing gasket, are furnished with aperture on baffle plate and the sealing gasket, are fixed with the baffle plate helical screw on the baffle plate, and two side shields are connected with draft tube and escape pipe respectively; Be provided with variable valve, vent valve, gas admittance valve and tensimeter successively between from the air intake opening to the baffle plate on the described draft tube, be provided with alarm and protection solenoid valve, tensimeter and vent valve successively between from the baffle plate to the gas outlet on the described escape pipe; Be provided with liquid spraying kettle in the described frame, be provided with liquid spraying kettle draft tube between the air intake opening of liquid spraying kettle and draft tube, and liquid spraying kettle draft tube is provided with leak detection liquid gas admittance valve, liquid spraying kettle and extraneous UNICOM are provided with the liquid kettle gas outlet of spraying; Tensimeter on the described escape pipe is connected with warning device.
In the such scheme, described sealing gasket is the silica gel sealing pad, prevents to leak gas in the middle of the valve.
In the such scheme, described warning device is provided with pilot lamp, alarm and switch.
In the such scheme, described frame bottom is provided with wheel, convenient moving.
The resulting valve leak detection of the utility model isolated plant, valve to be checked is placed on the intermediate tray, and be adjusted to suitable height, with two side shield fixing seal valve both sides, valve to be measured is in opening state, the pressure at both sides table is consistent not to have pressure, close valve to be measured, the draft tube air inlet does not represent that then valve is air tight if the tensimeter on the escape pipe has pressure, can normally use; If the tensimeter on the escape pipe has pressure to show, open leak detection liquid gas admittance valve, the liquid of will hunting leak, bubble occurs and represents valve leakage out of steam system to tested valve by the vent pipe spray, and no bubble is represented valves leakage.When the tensimeter on the escape pipe showed that pressure surpasses limit value, equipment can start acoustic-optic alarm, regulates alarm and protection warning device solenoid valve automatically.
This structure is used to detect the valve very high accuracy of whether leaking gas, and simple to operate, and security is very high, and cost is low, and wherein required part also obtains easily, all is good selection no matter be that economy or operation go up.
