Description
Technical field
The utility model relates to a kind of power valve air tight test device.
Background technology
For guaranteeing that this device is normal, use and the suitable storage time limit, the sealing property of power valve is had to certain requirement, requiring has certain antiseep ability to gas and liquid.So must absolutely check power valve air-tightness.Check adopts the hot water test method check in GJB 4403.Requirement immerses this device than in the hot water of high 28 ℃ of pretreatment temperature, under 30KPa air pressure, keeps 30S air tight, does not produce continuous or recurrent interrupted bubble.
Traditional power valve air tight test device comprises: sealing gasket, seal pad, screw rod, pull bar.Check is during product, first single power valve product be placed on seal pad, in sealing gasket.Use spanner rotary screw, the tight shrouding of screw top makes it sealing.Again frock is moved into water tank (frock connects power valve about 25KG altogether), add air pressure.Observe on power valve and have and do not have Bubble formation.Inspect a product and with spanner, screw rod has been unscrewed again, taken out product.This verifying attachment is wanted artificial degree of tightness screw rod, manually moves into, takes out of water tank.Labour intensity is large, and people will contact water, operating environment is poor, and once can only check a product, and efficiency is low.Had a strong impact on the integral production progress of this product.
Utility model content
Its object of the utility model is just to provide a kind of power valve air tight test device, has solved the problem of power valve impermeability quick test, have simple in structure, check feature fast, and labour intensity is low, efficiency is high.
The technical scheme that realizes above-mentioned purpose and take, comprise water tank, described water tank one side is provided with cylinder saddle, and cylinder is installed on cylinder saddle, and water tank opposite side is provided with fixed head bearing, fixed head bearing is provided with register pin, fixed head bearing is connected and fixed plate through taper roll bearing, and described cylinder output terminal connects push pedal through coupling shaft, taper roll bearing, and push pedal is provided with sealing gasket, hose adapter, described fixed head is provided with internal diameter positioning table, on internal diameter positioning table, power valve is installed.
Compared with prior art the utlity model has following advantage.
Adopt cylinder to drive push pedal campaign sealing power valve, adopted bull design (four-head) once can check four products simultaneously.By rotation, just can drive the product introduction water surface to complete fast air tight test.And by half-twist, drive product to surface during loading/unloading products, convenient operation.Thereby designed a kind of accumulating and sent out power valve impermeability Rapid checking device integrated, design concept is reliable, simple in structure.Use result shows, the feature such as this air tight test device has easy to operate, and speed is fast, and efficiency is high, and labour intensity is low, highly versatile (cylinder stroke leaves surplus, can check the power valve product of different length).
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic front view;
Fig. 2 is this apparatus structure diagrammatic side view.
Embodiment
This device comprises water tank 1, as shown in Figure 1, 2, described water tank 1 one sides are provided with cylinder saddle 16, cylinder 21 is installed on cylinder saddle 16, water tank 1 opposite side is provided with fixed head bearing 12, fixed head bearing 12 is provided with register pin 11, fixed head bearing 12 is connected and fixed plate 10 through taper roll bearing 17, described cylinder 21 output terminals connect push pedal 4 through coupling shaft 3, taper roll bearing 17, push pedal 4 is provided with sealing gasket 5, hose adapter 6, described fixed head 10 is provided with internal diameter positioning table 9, and power valve 8 is installed on internal diameter positioning table 9.
