Abstract
The utility model discloses a single -point leak hunting frock for advancing pipeline welding parts, including last section of thick bamboo cover, a lower cover, locking clip and locking screw, upward section of thick bamboo cover and lower cover main part are hollow semicircular cylinder column structure, and upward section of thick bamboo cover, lower cover terminal surface align to coordinate to connect and contain the welding seam position on the pipeline in inside, the diametric(al) that goes up section of thick bamboo cover and lower tin cover bottom surface department is equipped with two auricles outward respectively, and the auricle position of two covers is placed in to the locking clip sunk part that is concave type, compresses tightly two auricles through locking screw, and the contact surface cooperation that compresses tightly two auricles of back forms the sealed face in a plane, cylinder annular space that inside formation has a perfect understanding. The utility model discloses realize leaking whole acquisition and analysis that collect of working medium, reduced the loss of leaking the medium, improved detection accuracy.
Description
Technical field
The utility model relates to the auxiliary mould of a kind of single-point leak detection, encapsulates when can be used for the single-point leak detection of satellite booster pipeline welding position to tested position.
Background technology
The assembling of satellite booster pipeline all adopts the mode of butt welding, will form circular weld in welding processes.If fruit exists defective workmanship, commissure will there will be leakage phenomenon.In order to check the airtight quality of weld seam, when adopting suction gun leak locator to carry out the leak detection of weld seam single-point, needing to take encapsulating frock butt welded seam position to carry out coated, quantitative detection can be realized.The detection method of current employing is, adopts the encapsulating material such as plastic sheeting or medical proof fabric to encapsulate tested position, then inserts leak locator suction gun probe and detects, measure leakage rate.Adopt the encapsulating material Shortcomings part such as film, one to be film with weld seam peripheral part poorly sealed, and the leaking medium be collected exists part escape, causes test data inaccurate; Two is that leak locator suction gun and encapsulating material cannot be combined closely, and there is leaking medium equally and collects infull problem; Three need coated enforcement again when being duplicate detection, and efficiency is low; Four be operating space less time, cannot encapsulating operation be completed.
Utility model content
Technology of the present utility model is dealt with problems and is: for overcoming the deficiencies in the prior art, providing a kind of highly versatile, seal reliably, is convenient to implement, can improving the single-point leak detection tool equipment for advancing pipeline welding position of test accuracy.
Technical solution of the present utility model is:
A kind of for advancing the single-point leak detection tool equipment of pipeline welding position, comprise barrel cover, lower barrel cover, locking clamp and lock-screw, upper barrel cover and lower barrel cover main body are the semi-circular cylindrical structure of hollow, and the alignment of upper barrel cover, lower barrel cover end face is connected and the weld seam position on pipeline is included portion;
Two auricles are respectively equipped with outside the diametric(al) at upper barrel cover and lower barrel cover bottom surface place, locking clamp depressed area in matrix is placed in the auricle position of two barrel covers, by lock-screw, two auricles are compressed, after compressing, the surface of contact of two auricles coordinates formation flat seal face, the cylinder annular space that inner formation is through;
Upper barrel cover cylinder top is provided with the suction gun mouth matched with suction gun size, and lower barrel cover cylinder bottom is provided with air intake opening, suction gun mouth and air intake opening position axis collinear, and aligns with the weld seam position of pipeline.
The surface of contact of two described auricles is provided with hermetically-sealed construction, for realizing the thorough sealing of two auricles.
The hollow space of upper barrel cover and the hollow space of lower barrel cover measure-alike.
The two side ends mask of upper barrel cover, lower barrel cover has the semicircle orifice with the measure-alike diameter of pipeline matching part, can rotate after two barrel cover combinations around pipeline.
The utility model advantage is compared with prior art:
(1) the utility model utilizes the getter action of suction gun, extraneous air is entered from lower barrel cover air intake opening, formed from air intake opening to the air-flow of suction gun mouth, the medium that weld seam position is leaked is swept along suction gun mouth, leakage rate is detected by leak locator suction gun, solve the drawback that small space cannot use, applicability is stronger;
(2) the utility model realizes the whole collection collection analysises leaking working medium, reduces the loss of leaking medium, improves accuracy in detection;
(3) the utility model structure is simple, can the anglec of rotation arbitrarily after two barrel covers combinations, and one-step installation can repeated detection, and versatility is good.
