Abstract

The utility model discloses an air tightness detection device for products. The device comprises a bottom seat, a support, a transparent container filled with liquid, a clamp, an air inlet pipe, an air outlet pipe and a pressure gauge, wherein the support is fixed on the bottom seat; both ends of the clamp are connected with the support; the opening of the transparent container is sealed; the transparent container is held on the clamp; a valve is arranged at one end of the air inlet pipe, and the other end is immersed in the liquid of the transparent container; one end of the air outlet pipe is connected with a detected component, and the other end is located above the liquid level of the transparent container; and the pressure gauge is arranged on the air inlet pipe. The air tightness detection device for products has the advantages that the structure is simple, the cost is low, the detection process is simple, the leakage phenomenon is obvious, the operation is convenient, and no negative impact on the detected component is generated.

Description

The air-tightness detection device of product
Technical field
The utility model 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 to carry out sealing propertytest.Check whether faying face and plug exist leakage hidden danger.The method detecting 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 in practicality, detection efficiency is not high yet.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 gas, immerses in medium.But exist media attachment surface to be difficult to remove or parts are caused to certain damage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of air-tightness detection device of product is provided, simple in structure, cost is low, operation is also convenient.
The utility model is achieved through the following technical solutions: the utility model comprises base, support, fills the transparent vessel of liquid, clip, draft tube, escape pipe and tensimeter; 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 one end of escape pipe connects unit under test, the other end is positioned on the liquid levels of transparent vessel, and tensimeter is arranged in 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 utility model, described tensimeter is connected in draft tube by joint.
The opening of described transparent vessel is provided with sealing capping, and draft tube and escape pipe are separately positioned in sealing capping.
The utility model has the following advantages compared to existing technology: the utility model device structure is simple, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model 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 one 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 in 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 sealing capping, and draft tube 6 and escape pipe 9 are separately positioned in sealing capping.
Stretch below liquid level one end of draft tube 6, and one 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, opens the valve 5 of air inlet, to unit under test, inflates, if unit under test leaks, 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 there will not 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.
