Abstract
The invention provides an air-source pressure fast conversion device. According to the device, a first filter reducing valve 2 and a second filter reducing valve 3 are connected with a manual rotary valve 5 through pipelines; the first filter reducing valve 2 is connected to a first compressed air source 1 through a pipeline; the second filter reducing valve 3 is connected to a second compressed air source 4 through a pipeline; and the manual rotary valve 5 is connected with measured workpieces 7 through pipelines. According to the air-source pressure fast conversion device, the fast conversion of the air-source pressure of a power steering pump can be realized in an air tight test; and the work efficiency is greatly improved through one-step operation while high pressure precision is ensured; the labor intensity is lowered; and meanwhile, the damage to a pressure valve is avoided.
Description
Technical field
The present invention relates in air tightness test there being the product of bleed pressure requirement to carry out bleed pressure rapid translating technical field, particularly relating to the rapid translating technology of power assistance pump for steering bleed pressure in air tightness test.
Background technique
At present, in air tightness test, as fruit product has the requirement needing to change bleed pressure, operator generally adopt and regulate the mode of pressure valve to change pressure, result causes complex operation, inefficiency, and repeatedly regulate pressure valve for a long time, also may cause certain wearing and tearing to pressure valve, cause cost to increase.
Summary of the invention
In order to overcome the problems referred to above that the conversion of existing bleed pressure exists, the invention provides a kind of bleed pressure quick switching device.
The technological scheme that the present invention is adopted for achieving the above object is: bleed pressure quick switching device, first filtering pressure reducing valve 2 is connected hand rotary valve 5 with the second filtering pressure reducing valve 3 by pipeline, first filtering pressure reducing valve 2 connects the first source of compressed air 1 by pipeline, second filtering pressure reducing valve 3 connects the second source of compressed air 4 by pipeline, and hand rotary valve 5 connects measured workpiece 7 by pipeline.
Described hand rotary valve 5 is two-position four-way hand rotary valve.
Described hand rotary valve 5 is at least connected a measured workpiece 7 by pipeline with six logical 6.
Bleed pressure quick switching device of the present invention, can realize the rapid translating of power assistance pump for steering bleed pressure in air tightness test, and while guarantee elevated pressures precision, once-through operation also substantially increases working efficiency, reduce labor intensity, also avoid the damage to pressure valve simultaneously.
Accompanying drawing explanation
Fig. 1 is bleed pressure quick switching device schematic diagram of the present invention.
In figure: 1, the first source of compressed air, the 2, first filtering pressure reducing valve, the 3, second filtering pressure reducing valve, the 4, second source of compressed air, 5, hand rotary valve, 6, six lead to, and 7, measured workpiece.
Embodiment
Bleed pressure quick switching device principle of the present invention as shown in Figure 1, reality is primarily of source of compressed air, two filtering pressure reducing valves, two-position four-way hand rotary valves and connect workpiece pipe-line system to realize, first filtering pressure reducing valve 2 is connected two-position four-way hand rotary valve 5 with the second filtering pressure reducing valve 3 by pipeline, first filtering pressure reducing valve 2 connects the first source of compressed air 1 by pipeline, second filtering pressure reducing valve 3 connects the second source of compressed air 4 by pipeline, and hand rotary valve 5 is at least connected a tested pump of measured workpiece 7(by pipeline with six logical 6).
Working procedure: first tested pump is connected into by conduit and connects in workpiece pipe-line system and regulate two filtering pressure reducing valves 2 respectively, the pressure of 3, under being transferred to two pressure of test requirements document, then by source of compressed air 1, 4 by tubes connection in two filtering pressure reducing valves, two are selected to require different pressure by the stem position changing two-position four-way hand rotary valve, thus realize the rapid translating of power assistance pump for steering bleed pressure, and while guarantee elevated pressures precision, once-through operation also substantially increases working efficiency, reduce labor intensity, also avoid the damage to pressure valve simultaneously.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various change or equivalence replacement to these characteristic sum embodiment.In addition, under the teachings of the present invention, can modify to adapt to concrete situation and material to these characteristic sum embodiment and can not the spirit and scope of the present invention be departed from.Therefore, the present invention is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into belongs to protection scope of the present invention.
