Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of valve detection device, particularly a kind of dried test-run a machine of valve seal test.
Background technology
Valve must make a service test after general assembly is finished, and whether meets designing requirement and whether reaches the quality standard of national defined to check product.The sealing property of valve is one of leading indicator of examination valve mass quality.Except throttling valve, no matter be to cut off with valve or regulate and use valve, all should have certain sealing of closing, front need pursue platform and carry out leakage test so valve dispatches from the factory, and also will carry out Back seal test with the valve of upper sealing.And along with the development of producing, people are progressively improving the understanding of security, and in the manufacturing industry such as auto parts and components, gas appliance, various valve pressure regulators, device for detecting sealability plays a part more and more important.
A kind of instrument valve seal test device [application number: 201020214464.X is disclosed such as Chinese patent; Notification number: CN201707178U], source of the gas is connected with the second pressure regulator valve, the 3rd tensimeter, the first reversal valve, clamping cylinder successively pipeline, consists of to clamp passage; Source of the gas is connected with the first pressure regulator valve, the first tensimeter, the first stop valve, the second tensimeter, valve to be checked, the first reversal valve, the 3rd tensimeter, the second pressure regulator valve successively pipeline, consists of to detect the loop; Source of the gas is connected with the 3rd pressure regulator valve, the 4th tensimeter, the second stop valve, the 5th tensimeter, the second reversal valve, lift cylinder successively pipeline, consists of hoist trunk; The lift cylinder top is equipped with water tank.This instrument valve seal test device can be avoided operation with high pressure, has increased the security of test unit, has also reduced operating personnel's working strength simultaneously.
Yet above-mentioned instrument valve seal test device complicated structure will place valve to be checked the pond of water tank in testing process, leaks quantity valve leak is judged by observing bubble.Apparently, valve to be checked in soaking entry the time valve surface caused valve when also not using, just to produce the phenomenon of getting rusty by aqueous corrosion easily, thereby have influence on aesthetics even usability and the serviceable life of valve.
Other employings are soaked the valve seal pick-up unit that detects in the entry with valve and are also all existed the problems referred to above.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, can not affect the dried test-run a machine that valve performance, testing result are used for the valve seal test comparatively accurately when having proposed a kind of the detection.
The purpose of this utility model can realize by following technical proposal: a kind of dried test-run a machine for the valve seal test, comprise frame, it is characterized in that, described frame bottom has for the base of placing valve, described upper rack be provided with base over against push rod, also have on the described frame and can make push rod maybe can make base with respect to the hold-down mechanism of push rod upper and lower translation with respect to the base upper and lower translation, the up and down two ends of described push rod are respectively inlet end and outlet side, above-mentioned push rod inside has the inlet channel that inlet end is connected with the outlet side, described push rod lower end can be plugged in valve inlet end place and form sealing and above-mentioned inlet channel is communicated with valve cavity, has the mouth of detection on the described base, described base can be plugged in that valve export end place forms sealing and above-mentioned detection mouth communicates with valve cavity, also has on the described frame and detects mouth and be connected and can show that whether gas is by detecting mouthful air leakage display device of leakage.
Whether hold-down mechanism is clamped in valve between push rod and the base, and finally pass into air leakage display device by the gas that will detect usefulness and detect valve and leak gas.Because the entrance point of valve and endpiece form sealing with push rod and base respectively, so that in the testing process leakage situation can not appear, therefore so that the detection architecture accuracy rate is higher.Simultaneously because valve is not directly put into water and detected in testing process, therefore when detecting, can not cause the damage such as get rusty to the surface of valve yet, can not affect the serviceable life of valve yet.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described hold-down mechanism comprises the cylinder that is connected in upper rack, and the piston rod of above-mentioned push rod and cylinder is connected.Drive cylinder, piston rod drive push rod one in the same way base moves.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described hold-down mechanism comprises the cylinder that is connected in the frame bottom, and the piston rod of above-mentioned base and cylinder is connected.Drive cylinder, base the drive of piston rod next in the same way push rod move.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described push rod lower end has O-ring seal one, and makes formation sealing between the two by above-mentioned O-ring seal one when push rod is resisted against the valve inlet end.The O-ring seal one of push rod lower end forms sealing with the valve inlet end, detects gas in the time of can guaranteeing to detect and can not leak and testing result is impacted.
The dried test-run a machine that is used for the valve seal test above-mentioned has O-ring seal two on the described base, and above-mentioned O-ring seal two makes formation sealing between the two when the valve export end is positioned on the base.O-ring seal two on the base can guarantee to detect gas and can't leak between base and valve export end, thereby testing result is impacted.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described frame comprises base plate, support bar and mount pad, and above-mentioned base plate and mount pad are connected in respectively the two ends of vertical support bar, and above-mentioned base is positioned on the base plate, and above-mentioned cylinder is connected on the mount pad.
At the above-mentioned dried test-run a machine that is used for the valve seal test, also have on the described mount pad and can make the supercharging switch that communicates or close between inlet end and the source of the gas.Open the supercharging switch, inlet end communicates with source of the gas, thereby begins the sealing of valve is detected.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described air leakage display device comprises that transparent material and its inside have the tank body of water, described tank body is connected on the frame and its bottom has air intake opening, and above-mentioned detection mouth is connected with air intake opening and is provided with at the air intake opening place and can prevent that aqueous reflux is to detecting a mouthful filtering membrane that goes out in the tank body.This transition film is similar to the air transition film on the transfusion device, not only can discharge air, can prevent again the aqueous reflux in the tank body simultaneously.When detecting, if entering in the tank body, the gas that the valve export end is discharged produces bubble, illustrate that the impermeability of this valve is defective; If do not produce bubble, illustrate that this valve is specification product.
At the above-mentioned dried test-run a machine that is used for the valve seal test, described tank body is connected on the above-mentioned mount pad, and the air intake opening of described tank body is connected by connecting pipe with the detection mouth.
