Technical field
The present invention is a kind of a kind of device that is used for detecting the sealing property of nylon pipe, utilize this device that nylon pipe is clamped and shutoff, and be communicated with the gas circuit of special-purpose sealing detection instrument, measure the leakage rate of nylon pipe under certain pressure by means of special-purpose sealing detection instrument then.This device is applicable to the detection of the nylon pipe of various different length different-diameters.
Background technology
Nylon pipe mainly is to be used to be communicated with various gas circuits and oil circuit.For automobile or other mechanical hook-up form a complete production network, two ends have pipe adapter to nylon pipe described here specially.Pipe fitting will guarantee good air-tightness before dispatching from the factory, therefore need carry out hundred-percent Leak Detection before dispatching from the factory to each root finished product pipe fitting.This just needs a kind of mechanically connected sealing device for detecting leakage of nylon pipe that tested pipe fitting and special detector are coupled together.How with tested pipe fitting and special detector reliably, couple together apace present problem is, guarantees the sealing of its junction.Because tested pipe fitting is of a great variety, the diameter length of different types of pipe fitting has nothing in common with each other, and the restriction of receiver pipe connection place planform brings difficulty for the general mechanically connected sealing device of design.
Summary of the invention
The objective of the invention is to detect and a kind of mechanically connected sealing device of design couples together measured piece and special detector at the sealing property of the nylon pipe in the production reality.This device should be able to be applicable to the detection of the nylon pipe of various different length different-diameters, and the mode by the removable parts part to be satisfying the measurement requirement of various different pipe fittings, and guarantees that the junction positiver sealing does not leak, and is simple to operate, the efficient height.
Technical scheme of the present invention:
Mechanically connected sealing device for detecting leakage of nylon pipe is characterized in that: mainly by base and about two work the anchor clamps that clamp sealing functions and form.On base, be provided with T-slot, about the structures of two anchor clamps that rise to clamp sealing functions basic identical, respectively shutoff is carried out at the two ends of nylon pipe; About two base plates that rise to clamp the anchor clamps of sealing functions link to each other with base by T-slot, two anchor clamps can slide in T-slot and regulate relative position between two anchor clamps;
Described the anchor clamps that clamp sealing function are made up of latch mechanism, clamping sealing device;
The effect of described latch mechanism is that locking positioning is carried out in the end of nylon pipe.The structure of latch mechanism is: comprise bearing, an end of movable holddown is hinged by bearing pin and bearing, and two semicircle latch segments link to each other with movable holddown and bearing respectively by screw up and down, has arc groove and tested pipe fitting matches in the semicircle latch segment; Movable holddown is provided with flexible locking piece, and bearing is provided with locking key, and flexible locking piece is provided with the draw-in groove that can be stuck in locking key;
Described clamping sealing device mainly is made up of cylinder, push rod, pressure head, O-ring seal, rear end at latch mechanism is provided with bearing, push rod leads in bearing, putting back-end is connected with cylinder piston rod, pressure head is connected the push rod front end, has circular port in pressure head, and the pipe adapter of circular port and tested pipe fitting matches, be provided with ring groove in the circular port, O-ring seal is contained in the ring groove; In case clamp system clamps, O-ring seal is pressed on the circular arc sealing surface of pipe adapter of tested pipe fitting, and pressure head reliably is connected with pipe adapter;
The axis of described pressure head and the axis coaxle of tested pipe fitting;
Being provided with air flue therein in the pressure head of a clamping sealing device communicates with detection filling channel on the push rod.
The course of work: after determining the model of tested pipe fitting, regulate the distance between two anchor clamps, make its length consistent with tested pipe fitting.With the upwards upset of the movable holddown of latch mechanism, the end of pipe fitting to be measured is placed on the lower half circle latch segment, then movable holddown to be depressed, flexible locking piece is locked at movable holddown on the bearing automatically, the tested pipe fitting location that will be locked.Press the lower cylinder start button, cylinder rod will promote the pipe adapter that push rod and pressure head are pressed to tested pipe fitting, finish to be communicated with several shutoff actions.Start detection instrument, detecting instrument will be automatically to tested pipe fitting carry out pneumatic compression, pressurize, measure leakage rate, show testing result.Press the lower cylinder release button, the two ends cylinder unclamps, and pressure head separates with the pipe adapter of tested nylon pipe.Upwards pull flexible locking piece, movable holddown is upset upwards, takes off pipe fitting, detects and finishes.Carry out the next one then and detect circulation.
Beneficial effect: the present invention is a kind of mechanically connected sealing device for detecting leakage of nylon pipe that is used for production practices, rely on manual mode to finish the locking action of tested pipe fitting, by cylinder, pressure head, the tested pipe fitting of O-ring seal shutoff, can apace tested nylon pipe and detector be coupled together.Connect, seal reliably, operation is simple, and high efficiency, whole operation process only can be finished in the several seconds, applicable to different model, and the sealing detection of the nylon pipe of different length.
