Abstract
The invention discloses a gas tightness detection device for products. The gas tightness detection device comprises a base, supports, a transparent container filled with liquid, a hoop, a gas inlet tube, a gas outlet tube and a pressure gauge. The supports are fixed on the base, the two ends of the hoop are connected with the supports, an opening of the transparent container is sealed, the transparent container is clamped on the hoop, a valve is arranged at one end of the gas inlet tube, the other end of the gas inlet tube is soaked into the liquid in the transparent container, one end of the gas outlet tube is connected with a component to be detected, the other end of the gas outlet tube is located above the liquid level of the liquid in the transparent container, and the pressure gauge is arranged on the gas inlet tube. The gas tightness detection device is simple in structure, low in cost, simple in detection process, obvious in gas leakage judgment and convenient to operate and can not generate any negative effect on the component to be detected.
Description
Technical field
The present invention relates to a kind of device of the sealing propertytest for hydraulic pressure and Pneumatic component, in particular a kind of air-tightness detection device of product.
Background technology
For motor turning power-assisted oil pump and fork truck hydraulic part, in examination and test of products process, often need assembly is carried out to sealing propertytest.Check whether faying face and plug exist leakage hidden danger.The method detected has two kinds, and the one, purchase from the market special inspecting equipment.Because special inspecting equipment is not strong for product, so exist operation relatively loaded down with trivial details on practicality, detection efficiency is not high yet.The special inspecting equipment price is higher in addition, makes testing cost higher.Another kind of detection method is that detected member is directly passed into to gas, immerses in medium.But exist the media attachment surface to be difficult to remove or parts are caused to certain damage.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of air-tightness detection device of product is provided, simple in structure, cost is low, operation is also convenient.
The present invention is achieved by the following technical solutions: the present invention includes base, support, fill transparent vessel, clip, draft tube, escape pipe and the tensimeter of liquid; Described support is fixed on base, the two ends of clip are connected with support, the opening sealing of transparent vessel, transparent vessel is clamped on clip, one end of draft tube is provided with valve, and the other end immerses in the liquid in transparent vessel, and an end of escape pipe connects unit under test, the other end is positioned on the liquid levels of transparent vessel, and tensimeter is arranged on draft tube.
Described clip is provided with gib screw, in order to regulate the degree of tightness of clip.
As one of optimal way of the present invention, described tensimeter is connected on draft tube by joint.
The opening of described transparent vessel is provided with the sealing capping, and draft tube and escape pipe are separately positioned in the sealing capping.
The present invention has the following advantages compared to existing technology: present device is simple in structure, and cost is low; Testing process is simple, and whether gas leak phenomenon is obvious; Easy to operate; Can not produce any negative effect to detected parts.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below embodiments of the invention are elaborated, the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises base 1, support 3, fills transparent vessel 2, clip 4, draft tube 6, escape pipe 9 and the tensimeter 8 of liquid; Described support 3 is fixed on base 1, the two ends of clip 4 are connected with support 3, the opening sealing of transparent vessel 2, transparent vessel 2 is clamped on clip 4, one end of draft tube 6 is provided with valve 5, and the other end immerses in the liquid in transparent vessel 2, and an end of escape pipe 9 connects unit under test, the other end is positioned on the liquid levels of transparent vessel 2, and tensimeter 8 is connected on draft tube 6 by joint.Described clip 4 is provided with gib screw 10, in order to regulate the degree of tightness of clip 4.The opening of transparent vessel 2 is provided with the sealing capping, and draft tube 6 and escape pipe 9 are separately positioned in the sealing capping.
One end of draft tube 6 is stretched below liquid level, and an end connects source of the gas; Escape pipe 9 is above liquid level, and escape pipe 9 connects detected parts.During test, unnecessary hydraulic fluid port is blocked, an air intake opening that only retains unit under test, the escape pipe 9 that connects this device, open the valve 5 of air inlet, to unit under test, inflates, if unit under test leaks, the unit under test internal gas pressure can reduce, and vessel level top air pressure also can reduce simultaneously, and bubble can constantly appear in transparent vessel 2.If unit under test does not leak, the upper and lower air pressure of liquid level is consistent, just not there will be bubble phenomenon, and tensimeter 8 pointers are also very steady.Experiment finishes to close the valve 5 of air inlet, changes unit under test.
