Abstract
The utility model discloses the air-leakage test structure of a kind of valve body composition, described valve body composition comprises valve body, cover A and cover B, described cover A is connected with valve body interference fit respectively with cover B, described air-leakage test structure comprises detection workpiece, described detection workpiece to be placed in valve body and to be connected with valve body screw thread, the cavity formed in described valve body, between cover A and cover B is gas fill port, in described valve body, chamber corresponding to cover B opposite side be arranged on the leakage viewport detected on workpiece and be communicated with.It is after valve body forms that the utility model can overlap interference fit at body, to form with valve body coordinate by detecting workpiece, the sealing of body cover is detected, like this, valve body is formed before air-leakage test is arranged in performance test, in advance impermeability is detected to valve body composition, thus the judgement of fault when simplifying performance test, save repeated breaking-up and assembly working, reduce production cost, improve production efficiency.
Description
Technical field
The utility model relates to the air-leakage test structure of a kind of valve body composition.
Background technology
In the valve body composition of existing structure, require that body overlaps good seal, no-leak, at present, after the assembling of valve body composition completes, all can carry out the performance test of valve body composition, the fault that valve body composition exists is judged, and in breakdown judge, whether the impermeability of valve body composition is qualified is one of index detected, if valve body composition exists hermetic seal problem, then needs to disintegrate to valve body composition, re-assembly again, until its air-leakage test meets the requirements.Like this, then the repeated breaking-up likely causing valve body to form and assembly working, thus improve production cost, reduce production efficiency.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of detection architecture that can detect its impermeability before valve body composition makes a service test.
The technical solution of the utility model is achieved in that the air-leakage test structure that a kind of valve body forms, described valve body composition comprises valve body, cover A and cover B, described cover A is connected with valve body interference fit respectively with cover B, it is characterized in that: described air-leakage test structure comprises detection workpiece, described detection workpiece to be placed in valve body and to be connected with valve body screw thread, described detection workpiece leading section is provided with O RunddichtringO A, described O RunddichtringO A is between detection workpiece and cover A, described cover B is corresponding with the ledge structure place detected in the middle part of workpiece, planar seal ring is provided with between described cover B and the ledge structure detecting workpiece, described detection workpiece rearward end is provided with O RunddichtringO B, described O RunddichtringO B is between detection workpiece and valve body end face, in described valve body, the cavity formed between cover A and cover B is gas fill port, in described valve body, chamber corresponding to cover B opposite side be arranged on the leakage viewport detected on workpiece and be communicated with.
It is after valve body forms that the utility model can overlap interference fit at body, to form with valve body coordinate by detecting workpiece, the sealing of body cover is detected, like this, valve body is formed before air-leakage test is arranged in performance test, in advance impermeability is detected to valve body composition, thus the judgement of fault when simplifying performance test, save repeated breaking-up and assembly working, reduce production cost, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is valve body, 2 is cover A, and 3 is cover B, and 4 for detecting workpiece, and 5 is O RunddichtringO A, and 6 is planar seal ring, and 7 is O RunddichtringO B, and 8 is gas fill port, and 9 is chamber, and 10 for revealing viewport.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of air-leakage test structure of valve body composition, described valve body composition comprises valve body 1, cover A2 and cover B3, described cover A2 is connected with valve body 1 interference fit respectively with cover B3, described air-leakage test structure comprises detection workpiece 4, described detection workpiece 4 to be placed in valve body 1 and to be threaded with valve body 1, described detection workpiece 4 leading section is provided with O RunddichtringO A5, described O RunddichtringO A5 is between detection workpiece 4 and cover A2, described cover B3 is corresponding with the ledge structure place detected in the middle part of workpiece 4, planar seal ring 6 is provided with between described cover B3 and the ledge structure detecting workpiece 4, described detection workpiece 4 rearward end is provided with O RunddichtringO B7, described O RunddichtringO B7 is between detection workpiece 4 and valve body 1 end face, in described valve body 1, the cavity formed between cover A2 and cover B3 is gas fill port 8, in described valve body 1, chamber 9 corresponding to cover B3 opposite side be arranged on the leakage viewport 10 detected on workpiece 4 and be communicated with.
Principle of work of the present utility model is: after valve body and cover interference fit are good, detection workpiece installs O RunddichtringO A and planar seal ring, then will detect workpiece screws in valve body, sealed between detection workpiece leading section and cover A by O RunddichtringO A, detection work stage stage structure is between cover B by planar seal ring and seals, detect workpiece rearward end and sealed by O RunddichtringO B and valve body 1 end face.
After assembling, be filled with the air of certain pressure to gas fill port, at the valve body end face brush leak-checking agent of cover A and valve body Fit, judge the fit quality of cover A and valve body, if there is bubble to occur, then cover A and valve body fit quality bad, poor air-tightness; Detecting detection workpiece end face brush leak-checking agent corresponding to the leakage viewport of workpiece, judging the fit quality of cover B and valve body, if there is bubble to occur, then cover B and valve body fit quality bad, poor air-tightness.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
