Abstract
The invention discloses a component for obtaining a safe and stable low-pressure gas source, which comprises a vent pipe with a gas inlet and a gas outlet, wherein a first pressure reducing valve, a second pressure reducing valve and a safety valve are sequentially arranged on the vent pipe from the gas inlet to the gas outlet, a first pressure gauge is arranged on a pipe section between the two pressure reducing valves, and a second pressure gauge is arranged on a pipe section between the safety valve and the gas outlet. The invention has the advantage of converting a high-pressure air source into a low-pressure working air source safely and stably.
Description
Technical Field
The invention relates to an assembly for obtaining a safe and stable low-pressure gas source.
Background
At present, most of domestic low-pressure air is stored in a low-pressure air storage tank after the low-pressure air is generated by continuously running a low-pressure air compressor, or the low-pressure air is obtained by directly reducing the pressure of the high-pressure air through a pressure reducing valve. For factories and mines with high-pressure air sources on site, the purchase of the low-pressure air compressor and the air storage tank not only increases the cost, but also increases the maintenance content of the low-pressure air compressor, thereby causing the waste of financial resources and manpower.
For the use of a pressure reducing valve to directly convert high pressure gas to low pressure gas, there is a risk that if the pressure reducing valve fails, the high pressure gas will directly cross into the low pressure line and damage the equipment.
Disclosure of Invention
In order to solve the problem that the pipeline only using one pressure reducing valve has unstable air supply risk, the invention provides a component for obtaining a safe and stable low-pressure air source, which not only can directly convert high-pressure air into stable low-pressure air, but also can save a large amount of financial resources and manpower.
The invention relates to a component for obtaining a safe and stable low-pressure gas source, which comprises a vent pipe with a gas inlet and a gas outlet, wherein a first pressure reducing valve, a second pressure reducing valve and a safety valve are sequentially arranged on the vent pipe from the gas inlet to the gas outlet, a first pressure gauge is arranged on a pipe section between the two pressure reducing valves, and a second pressure gauge is arranged on a pipe section between the safety valve and the gas outlet.
For ease of operation, the first pressure relief valve and the second pressure relief valve are identical.
Has the advantages that: according to the invention, the first pressure reducing valve, the second pressure reducing valve and the safety valve are sequentially arranged on the vent pipe, the first pressure gauge is arranged between the two pressure reducing valves, and the second pressure gauge is arranged between the safety valve and the air outlet, so that the problem that the equipment is damaged due to unstable air supply caused by only arranging one pressure reducing valve on a pipeline in the prior art is solved; by providing both pressure reducing valves as the same pressure reducing valve, the operation is facilitated.

Detailed Description
The technical solution of the present invention is described in detail by the following examples, but the scope of the present invention is not limited to the examples.
Examples
As shown in figure 1, the invention is a component for obtaining a safe and stable low-pressure air source, which comprises a vent pipe 4 with an air inlet 7 and an air outlet 8, wherein a first pressure reducing valve 1, a second pressure reducing valve 2 and a safety valve 3 are sequentially arranged on the vent pipe 4 from the air inlet 7 to the air outlet 8, a first pressure gauge 5 with a pressure node is arranged on a pipe section between the two pressure reducing valves, a second pressure gauge 6 with a pressure node is arranged on a pipe section between the safety valve 3 and the air outlet 8, the two pressure gauges are both provided with auxiliary alarm contacts, and the first pressure reducing valve 1 and the second pressure reducing valve 2 are the same pressure reducing valve.
In actual operation, firstly adjusting the operation parameters of the equipment, namely, firstly adjusting the second pressure reducing valve 2, and ensuring that high-pressure gas can be safely reduced to a low-pressure working range when the first pressure reducing valve 1 fails; then the first pressure reducing valve 1 is adjusted to reduce the high pressure air source to be within the low pressure air source range. When the pipeline is connected and works, the first pressure reducing valve 1 reduces a high-pressure air source flowing in from the air inlet 7 to be within the working range of a low-pressure air source, the second pressure reducing valve 2 reduces the pressure of the low-pressure air source to be corresponding to the operating pressure of equipment, the low-pressure air source is used as working air to flow out from the air outlet 8 through the safety valve 3, and whether the working state of the first pressure reducing valve 1 is normal or not is monitored through the first pressure gauge 5 in the process; whether the working state of the second pressure reducing valve 2 is normal or not is monitored through the second pressure gauge 6, and an alarm is given when the working state is monitored to be abnormal. In the case of a failure of the first pressure reducing valve 1, the second pressure reducing valve 2 can completely reduce the pressure of the high-pressure air source to the working air pressure range; the first pressure reducing valve 1 is also able to achieve a source of low pressure to ensure safe operation of the apparatus if the second pressure reducing valve 2 fails.
As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
