Abstract
The utility model discloses a composite pressure testing tool for a corrugated pipe assembly. The composite pressure testing tool comprises a trough, a compressed air delivery device and a clamp for clamping the corrugated pipe assembly; and the clamp comprises two clamping blocks arranged coaxially, the two clamping blocks are arranged on the inner wall of the trough oppositely, the corrugated pipe assembly is hermetically connected between the two clamping blocks, and the two clamping blocks and the corrugated pipe assembly between the two clamping blocks have a closed air passage communicated with the air outlet of the compressed air delivery device in the axial direction. The composite pressure testing tool can be used for roughly detecting the sealing connection air-tightness of the corrugated pipe assembly by observing whether the trough has bubbles through naked eyes. The composite pressure testing tool is simple in structure and strong in practicability, and can be widely applied to air-tightness detection of the corrugated pipe assembly in medium and small enterprises.
Description
Technical field
The utility model relates to a kind of compound structure for pressure test, is used to detect the impermeability of bellows component.
Background technology
In the prior art, the impermeability that generally adopts helium mass analyzer to carry out bellows component detects, and therefore, helium mass analyzer costs an arm and a leg on the one hand, on the other hand, the complicated operation of helium mass analyzer, for medium-sized and small enterprises, its application cost is high, is unfavorable for the existence of enterprise.
The utility model content
The utility model provides a kind of compound structure for pressure test of bellows component to the deficiency of prior art, and it is simple in structure, and is practical, and the impermeability that can be widely used in bellows component in the medium-sized and small enterprises detects.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of compound structure for pressure test of bellows component comprises tank, compressed air delivery device and the anchor clamps that are used for the clamping bellows component; Said anchor clamps comprise the grip block of two coaxial settings; This two grip block relatively is installed in the inwall of tank; Bellows component is sealedly connected between two grip blocks, and the bellows component that two grip blocks reach therebetween has the closed vent road that is communicated with compressed air delivery device gas outlet along axis.
The periphery of said grip block is provided with more than one cylindrical T type limiting stand; Annular seal groove is offered in the periphery of the minor diameter cylinder of this cylindrical T type limiting stand, and the tube chamber of said bellows component is tightly connected through O RunddichtringO and the T type limiting stand that is embedded in the annular seal groove.
In described two grip blocks; One of them grip block is offered the air hole of perforation along axis; Another grip block is then offered semiclosed air hole along axis; And the opening end of this semiclosed air hole is adjacent with the air hole of perforation one end, and the air hole other end that connects then is communicated with compressed air delivery device gas outlet.
Said compressed air delivery device comprises air pump and operation valve, and operation valve is installed on the connecting tube between air pump gas outlet and the closed vent road.
According to above technical scheme, can realize following beneficial effect:
The utility model grasps bellows component hermetically through two grip blocks; And toward two grip blocks and therebetween bellows component along feeding pressurized air in the closed vent road that axis has, then can carry out the bellows component bubble-tight detection that is tightly connected roughly through whether there being bubble in the visual inspection tank.Hence one can see that, and this apparatus structure is simple, and is practical, and the impermeability that can be widely used in bellows component in the medium-sized and small enterprises detects.
