Description

Technical Field

[0001] The utility model belongs to the field of oil pressure measurement and relates to an oil pressure measuring device. Background Art

[0002] The filter seat is typically installed at the fuel filler port of a vehicle's fuel tank and typically utilizes a one-way valve structure to prevent oil spills when the vehicle is traveling on bumpy roads while also ensuring unobstructed air flow into the tank. Traditionally, specialized pressure testing tools have been used to measure the filter seat pressure, which is complex and time-consuming. The filter seat pressure is relatively low, requiring high precision, making conventional pressure testing equipment difficult to meet and resulting in high testing costs. Utility Model Content

[0005] An oil pressure measuring device includes a clamp body 1, a connecting seat 2, and a sealing gasket 3;

[0006] The clamp body 1 is a hollow cylinder, and a stepped hole is provided at the lower end of the clamp body 1 for installing the connecting seat 2;

[0007] The connecting seat 2 is a hollow cylinder with open ends, and the upper end of the connecting seat 2 is provided with internal and external threads;

[0008] Connect the filter seat and the inner wall of the connecting seat 2 through threads, screw both of them into the lower end of the clamp body 1 through threads, and place a sealing gasket 3 on the contact surface between the step hole of the clamp body 1 and the connecting seat 2 to prevent oil leakage.

[0009] Furthermore, a through hole is provided on the side wall of the connecting seat 2 for tightening the clamp body 1 and the connecting seat 2 using a tool.

[0010] Furthermore, a blind hole is provided on the side wall of the clamp body 1 for tightening the clamp body 1 and the connecting seat 2 using a tool during installation.

[0011] Furthermore, pour diesel from the upper port of the clamp body 1 until the diesel reaches the oil height line and the A surface is flush; observe whether there is oil leakage from the bottom to determine whether the product meets the requirements.

[0012] The advantage of the utility model is that the provided pressure measuring device can conveniently and accurately test whether the sealing performance of a product meets the requirements, thereby reducing product testing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is combined with Figure 1 and attached Figure 2 The utility model is described in further detail.

[0016] like Figure 2 As shown, the present invention provides an oil pressure measuring device comprising a clamp body 1, a connecting base 2, and a sealing gasket 3. The clamp body 1 is a hollow cylinder with a stepped hole at its lower end for mounting the connecting base 2. Blind holes are provided in the side walls of the clamp body 1 for tightening the clamp body 1 and connecting base 2 with a tool during installation. The inner wall of the upper end of the clamp body 1 is marked with an oil level line.

[0017] The connecting seat 2 is a hollow cylinder with open ends. A through hole is provided on the side wall of the connecting seat 2 for tightening the clamp body 1 and the connecting seat 2 with a tool. The upper end of the connecting seat 2 is provided with internal and external threads.

[0018] Connect the filter seat and the inner wall of the connecting seat 2 through threads, screw both of them into the lower end of the clamp body 1 through threads, and place a sealing gasket 3 on the contact surface between the step hole of the clamp body 1 and the connecting seat 2 to prevent oil leakage.

[0019] The working principle of the oil pressure measuring device of the utility model is:

[0020] By simulating the use environment of the filter seat in the vehicle fuel tank, according to the filter seat sealing pressure requirements, the oil height required for the same pressure is calculated, and the oil is injected to determine whether the sealing performance of the one-way valve meets the requirements. The measurement process of the oil pressure measuring device is as follows:

[0021] 1. Pour diesel oil into the upper port of the clamp body 1, so that the diesel oil reaches the oil level line and the A surface is flush. Figure 1 As shown;

[0022] 2. Observe for any leakage.

[0023] Based on the filter seat pressure requirements, calculate the height from surface A to the filter seat sealing steel ball surface to obtain the filter seat sealing pressure. During operation, inject oil into the inner cavity of clamp body 1 to a height flush with surface A. Observe from below for oil leakage to determine whether the product meets the requirements.
