Background technology
The method of hunting leak for the airtight container that contains certain pressure generally comprises water leak detection, soap bubble leak detection, helium mass spectrometer leak etc.The method of water inspection is generally that pressure vessel is placed in water, judges whether to leak by observing bubble; The method of soap bubble leak detection is generally that easy leakage position is coated to soap lather water, judges whether to leak by visual inspection; The method of helium mass spectrometer leak is the helium that is filled with certain pressure intensity after tested workpiece is found time, tested workpiece outside is the vacuum tank with the requirement of certain vacuum degree, vacuum tank and helium mass spectrometer leak detector leak detection mouthful are joined, if tested workpiece has leakage, the helium of the vacuum tank that bleeds can be measured by helium mass spectrometer leak detector.All more complicated of the method for above three kinds of leak detections, to having relatively high expectations of particular device, and the relatively effort that operates.
Summary of the invention
The utility model technical issues that need to address are: existing method more complicated of hunting leak for pressure piping, and to having relatively high expectations of particular device, and the relatively effort that operates.
For above-mentioned technical matters, the utility model is taked following technical scheme:
A kind of pick-up unit of pressure piping seepage, described pick-up unit is uncovered polyhedral, at least has a pair of relative and parallel side, and described polyhedron has double-decker, between double-decker, have end to end groove 1, described groove 1 is for putting blown-in-place blood gasket; Described relative and parallel side is provided with one and aligns right semicircular pipeline holding hole 4; On the side of described pick-up unit, be also provided with pressure tap 3 and sealing gasket air-filled pore 2.
In the time carrying out leak detection, need to adopt a pair of box body combinations to use, now blown-in-place blood gasket is placed in groove 1, the valve inside of sealing gasket is passed to sealing gasket air-filled pore 2, by this air-filled pore, sealing gasket is inflated, tensimeter is connected by flexible pipe and pressure tap 3, and tensimeter pressure is equilibrium state; The joint of pressure pipeline is placed in casing, pipeline is shelved on pipeline holding hole 4, then uses on another symmetrical Box Cover, the inside and outside formation sealing of casing, change by observing manometric pressure, can judge whether this joint of pipeline has leakage; Hunted leak in each joint on pipeline one by one, the process of the leak detection of complete twin conduit the whole series.
Further, described sealing gasket air-filled pore 2 is L-shaped, and groove 1 medial surface is communicated with the lateral surface of pick-up unit.
Further, the rectangular body structure of described pick-up unit.
Further, also comprise U-shaped pressure detection pipe, described U-shaped pressure detection pipe is communicated with pressure tap 3 by flexible pipe.
Further, the side of described casing is also provided with snap close, for being connected with another casing.
The beneficial effects of the utility model are:
1) leak detection mode is simple to operate, time saving and energy saving.
2) provide a kind of method of easy pipeline leak detection, lower to equipment requirement.
3) precision of detecting leak gas is higher, evaluation that can quantitative to the degree of leaking.
4) simple in structure, cost is low, and practicality is good.
