Abstract
The invention relates to an air pressure reducing valve group, comprising stop valves, stop check valves, pressure reducing valves, filters, safety valves and pressure gages, wherein the valve group consists of more than two pressure reducing units; the pressure reducing units are mutually connected in parallel; an input end of each pressure reducing unit is connected with the stop valve, the filter, the pressure reducing valve, the safety valve, the stop check valve and an output end in order; the pressure reducing units are connected through flanges and seamless steel pipes; and the input end and the output end of at least one pressure reducing unit of the valve group are provided with one pressure gage respectively. In comparison with the prior art, the air pressure reducing valve group causes several pressure reducing units to be mutually connected in parallel through the flanges and the seamless steel pipes for the formation of the air pressure reducing valve group; therefore, the structure is compact and the installation is convenient; and moreover, the size is smaller, the installation period is shortened and the working efficiency and the installation quality are improved.
Description
Technical field
The present invention relates to the reduction valve group, especially a kind of medium-low pressure reducing valve group for air dielectric.
Background technique
Existing reduction valve group generally is for the fluids such as air are carried out throttling, filtration and decompression.At present, a decompressing unit of reduction valve group is comprised of stop valve, screw down nonreturn valve, reduction valve, filter, safety valve and pressure gauge usually, existing reduction valve group often adopts several decompressing unit parallel connections or is connected in series composition, is using on-the-spot the installation to connect.Because on-the-spot installation need to connect reduction valve group and decompressing unit by pipeline, not only installation is inconvenient, working efficiency is lower, and volume is larger, loosely organized, installation period is longer.
Summary of the invention
For the deficiency of above existing reduction valve group, the purpose of this invention is to provide a kind of mesolow air reducing valve group for air dielectric.
The objective of the invention is by realizing by the following technical solutions:
The air reducing valve group comprises stop valve, screw down nonreturn valve, reduction valve, filter, safety valve and pressure gauge, and described valve group is comprised of two above decompressing unit, and each decompressing unit is parallel with one another or be connected in series;
The input end of described each decompressing unit connects stop valve, filter, reduction valve, safety valve, screw down nonreturn valve and output terminal successively, interconnect by flange and seamless steel pipe between the described decompressing unit, described valve group has at least the input end of a decompressing unit and output terminal to be respectively equipped with pressure gauge.
As the preferred technical solution of the present invention, described valve group is composed in parallel by two decompressing unit, interconnects by flange and seamless steel pipe between two decompressing unit;
Be provided with pressure gauge between the stop valve of the import of described valve group and the first decompressing unit, be provided with pressure gauge between the screw down nonreturn valve of the first decompressing unit and the outlet of valve group.
As the preferred technical solution of the present invention, described filter is y-type filter.
As the preferred technical solution of the present invention, described pressure gauge is liquid-filled pressure gauge.
As the preferred technical solution of the present invention, mutually connect by flange between the input end of described decompressing unit, stop valve, filter, reduction valve, safety valve, screw down nonreturn valve and the output terminal and fixing.
The invention has the beneficial effects as follows: with respect to prior art, the present invention with several decompressing unit by flange and the seamless steel pipe air reducing valve group that connects to form parallel with one another, not only compact structure, easy for installation, and small volume, installation period shorten, and have improved working efficiency and installation quality.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the air reducing valve group comprises stop valve 1, screw down nonreturn valve 5, reduction valve 3, filter 2, safety valve 4 and pressure gauge, and described valve group is comprised of two above decompressing unit, and each decompressing unit is parallel with one another or be connected in series; The input end of described each decompressing unit connects stop valve 1, filter 2, reduction valve 3, safety valve 4, screw down nonreturn valve 5 and output terminal successively, interconnect by flange and seamless steel pipe between the decompressing unit, described valve group has at least the input end of a decompressing unit and output terminal to be respectively equipped with pressure gauge.
In the present embodiment, described valve group is composed in parallel by two decompressing unit, interconnects by flange and seamless steel pipe between two decompressing unit.Be provided with between the stop valve 1 of valve group import 6 and the first decompressing unit between the screw down nonreturn valve 5 of pressure gauge 8, the first decompressing unit and the valve group outlet 7 and be provided with pressure gauge 9.The described filter 2 of present embodiment is y-type filters, and described pressure gauge is liquid-filled pressure gauge.Mutually connect by flange between the input end of the described decompressing unit of present embodiment, stop valve 1, filter 2, reduction valve 3, safety valve 4, screw down nonreturn valve 5 and the output terminal and fixing.
