Description
Technical field
The utility model relates to a kind of subway air supply system Aspirating valves for subway brake system and door contact interrupter.
Background technique
Aspirating valves and bleeder valve on existing subway generally all separate, volume is larger, take when mounted larger area, between bleeder valve and Aspirating valves, adopt pipeline to be connected, cost is high, leakage point is many, and bleeder valve is spring, flow area is less like this, the speed of releasing is slower, cannot discharge air compressor system pressure completely, and subway requires the rear internal system pressure of shutdown to drop in a short period of time zero with air supply system, and existing Aspirating valves and bleeder valve delivery system internal pressure completely, so requirement of iron winds origin system fully contentedly, the control of bleeder valve also need to be by electromagnetic valve in addition, reduce reliability, and increase cost of production.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of bleeder valve and the design of suction valve integral type are provided, compact structure, and leakage point is few, can discharge the subway air supply system Aspirating valves of air compressor system pressure completely.
The purpose of this utility model is achieved through the following technical solutions: a kind of subway air supply system Aspirating valves, comprise Aspirating valves and bleeder valve, and Aspirating valves and bleeder valve are integral type.
Further improvement of the utility model is: described Aspirating valves comprises valve body, one end of valve body is Aspirating valves import, the other end of valve body communicates with bleeder valve by the bleeder valve outlet in valve body, the bottom of valve body is the Aspirating valves outlet communicating with Aspirating valves import, in Aspirating valves outlet, is provided with the safety check contacting with valve body.
Further improvement of the utility model is: described bleeder valve comprises bleeder valve valve body, in bleeder valve valve body, be provided with mangetic core assembly, the top of mangetic core assembly is provided with valve gap, valve gap is provided with bleeder valve entrance, the bottom of mangetic core assembly is provided with end cover, between mangetic core assembly and end cover, be bleeder valve control mouth, bleeder valve control mouth communicates with Aspirating valves outlet by passage.
Further improvement of the utility model is: described safety check comprises non-return valve core, spring seat, and spring socket sleeve, on non-return valve core, is provided with spring between non-return valve core and described spring seat, and spring seat uses jump ring and non-return valve core to fix by hole.
Further improvement of the utility model is: between described valve gap and bleeder valve valve body, between mangetic core assembly and bleeder valve valve body, be equipped with seal ring between end cover and bleeder valve valve body.
The utility model compared with prior art has the following advantages:
1. adopt non-spring structure bleeder valve, flow area is large, compares former spring bleeder valve, and the speed of releasing is fast, can discharge air compressor system pressure completely, and former spring bleeder valve delivery system pressure completely.
2. bleeder valve, by the control of main frame internal pressure, without the control of external electromagnetic valve, had both improved reliability, had reduced again cost.
3. non-return valve core localization part is local contact, and frictional force is little, is not easy jam, and check function is reliable.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-valve body, the import of 2-Aspirating valves, the outlet of 3-bleeder valve, the outlet of 4-Aspirating valves, 5-bleeder valve valve body, 6-mangetic core assembly, 7-valve gap, 8-bleeder valve entrance, 9-end cover, 10-bleeder valve control mouth, 11-passage, 12-non-return valve core, 13-spring seat, 14-spring, 15-be jump ring, 16-seal ring for hole.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the embodiment of a kind of subway air supply system of the utility model Aspirating valves, comprise Aspirating valves and bleeder valve, Aspirating valves and bleeder valve are integral type, Aspirating valves comprises valve body 1, one end of valve body 1 is Aspirating valves import 2, the other end of valve body 1 communicates with bleeder valve by the bleeder valve outlet 3 in valve body 1, the bottom of valve body 1 is the Aspirating valves outlet 4 communicating with Aspirating valves import 2, in Aspirating valves outlet 4, be provided with the safety check contacting with valve body 1, bleeder valve comprises bleeder valve valve body 5, in bleeder valve valve body 5, be provided with mangetic core assembly 6, the top of mangetic core assembly 6 is provided with valve gap 7, valve gap 7 is provided with bleeder valve entrance 8, the bottom of mangetic core assembly 6 is provided with end cover 9, it between mangetic core assembly 6 and end cover 9, is bleeder valve control mouth 10, bleeder valve control mouth 10 communicates with Aspirating valves outlet 2 by passage 11, safety check comprises non-return valve core 12, spring seat 13, spring seat 13 is enclosed within on non-return valve core 13, between non-return valve core 12 and spring seat 13, be provided with spring 14, spring seat 13 uses jump ring 15 fixing with non-return valve core 12 by hole, between valve gap 7 and bleeder valve valve body 5, between mangetic core assembly 6 and bleeder valve valve body 5, between end cover 9 and bleeder valve valve body 5, be equipped with seal ring 16.
