Description
Technical field
The present invention relates to a kind of subway air supply system inlet valve for subway brake system and door contact interrupter.
Background technology
Inlet valve and bleeder valve on existing subway are the most separate, and volume is relatively big, takies bigger when mounted
Area, between bleeder valve with inlet valve use pipeline is connected, cost height, leakage point is many, and bleeder valve is spring, the most logical
Flow area is less, and speed of releasing is slower, it is impossible to release air compressor system pressure completely, and subway air supply system requires to stop
After machine, internal system pressure needs to drop in a short period of time zero, and existing inlet valve can not discharge completely with bleeder valve
Internal system pressure, thus can not the requirement of iron winds origin system the most contentedly, additionally the control of bleeder valve also needs to by electromagnetism
Valve controls, and reduces reliability, and adds production cost.
Summary of the invention
The invention aims to overcome above deficiency, it is provided that a kind of bleeder valve and intake valve unitary design, knot
Structure is compact, and leakage point is few, can discharge the subway air supply system inlet valve of air compressor system pressure completely.
The purpose of the present invention is achieved through the following technical solutions: a kind of subway air supply system inlet valve, including inlet valve
With bleeder valve, inlet valve and bleeder valve are integral type.
Further improvement of the present invention is: described inlet valve includes valve body, and one end of valve body is inlet valve import, valve body
The other end exported by bleeder valve in valve body and communicate with bleeder valve, the bottom of valve body is the air-breathing communicated with inlet valve import
Valve outlet port, is provided with, in inlet valve outlet, the check-valves contacted with valve body.
Further improvement of the present invention is: described bleeder valve includes bleeder valve valve body, is provided with spool in bleeder valve valve body
Assembly, the top of core assembly is provided with valve gap, and valve gap is provided with bleeder valve entrance, and the bottom of core assembly is provided with end cover,
Controlling mouth for bleeder valve between core assembly and end cover, bleeder valve is controlled mouth and is communicated with inlet valve outlet by passage.
Further improvement of the present invention is: described check-valves includes non-return valve core, spring base, and spring socket sleeve is at check-valves
On core, being provided with spring between non-return valve core and described spring base, spring base is fixed with non-return valve core by hole jump ring.
Further improvement of the present invention is: between described valve gap and bleeder valve valve body, core assembly and bleeder valve valve body
Between, be equipped with sealing ring between end cover and bleeder valve valve body.
The present invention compared with prior art has the advantage that
1. using non-spring structure bleeder valve, flow area is big, compares former spring bleeder valve, and speed of releasing is fast, permissible
Release air compressor system pressure completely, and former spring bleeder valve cannot discharge system pressure completely.
2. bleeder valve is controlled by main frame internal pressure, it is not necessary to external electrical magnet valve controls, and had both improve reliability, and had reduced again
Cost.
3. non-return valve core position portion is localized contact, and frictional force is little, it is not easy to jam, and check function is reliable.
Accompanying drawing illustrates:

Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
As Fig. 1 shows the detailed description of the invention of the present invention a kind of subway air supply system inlet valve, including inlet valve and letting out
Putting valve, inlet valve and bleeder valve is integral type, and inlet valve includes that valve body 1, one end of valve body 1 are inlet valve import 2, valve body 1
The other end exports 3 by the bleeder valve in valve body 1 and communicates with bleeder valve, and the bottom of valve body 1 is the suction communicated with inlet valve import 2
Air valve outlet 4, is provided with, in inlet valve outlet 4, the check-valves contacted with valve body 1, and bleeder valve includes bleeder valve valve body 5, bleeder valve
Being provided with core assembly 6 in valve body 5, the top of core assembly 6 is provided with valve gap 7, and valve gap 7 is provided with bleeder valve entrance 8, core assembly
The bottom of 6 is provided with end cover 9, controls mouth 10 for bleeder valve between core assembly 6 and end cover 9, and bleeder valve controls mouth 10
Being communicated with inlet valve outlet 4 by passage 11, check-valves includes non-return valve core 12, spring base 13, and spring base 13 is enclosed within check-valves
On core 12, being provided with spring 14 between non-return valve core 12 and spring base 13, spring base 13 is by hole jump ring 15 and non-return valve core 12
Fixing, between valve gap 7 and bleeder valve valve body 5, between core assembly 6 and bleeder valve valve body 5, end cover 9 and bleeder valve valve body 5
Between be equipped with sealing ring 16.
Air supply system inlet valve subway to be used for brake system of the present invention and door contact interrupter, working method is for being interrupted
Sex work, the integrated bleeder valve of inlet valve, inlet valve relies on the pressure reduction before and after valve, automatically opens up, air compressor machine normal load, work as aerofluxus
After pressure reaches setting value, air compressor machine is shut down, and inlet valve spool resets under spring force, by the pressure in head suction muffler
Defeating tight seal spool, the pressure in head suction muffler passes through internal path simultaneously, enters the control end of bleeder valve, due to area
The principle of difference, promotes piston to open, and internal system pressure is vented rapidly by bleeder valve, the most contentedly iron winds origin system for
After shutdown, internal system pressure is vented to rapidly the requirement of zero.
