Description
Technical field
The utility model is related to a kind of controller, and in particular to a kind of ventilating control valve.
Background technology
The major function of ventilating control valve is to ensure the normal gas supply of diver of quick diving dress of escaping danger.With
Deep ocean work is continued to develop, and the research to diver's underwater escape is increasingly valued by people.Implementing underwater escape
When, diver needs diving dress of quickly escaping danger, into the pressurization of Quick-pressing cabin, treats pressure and extraneous hydraulic pressure in Quick-pressing cabin
After balance, open and covered on compression chamber, diver leaves Quick-pressing cabin, the buoyancy provided by diving dress of quickly escaping danger, quickly
Float up to the water surface., it is necessary to be inflated by inflation system for quick diving dress of escaping danger in pressure process in Quick-pressing cabin, it is ensured that
Diver's eupnea.The air demand of conventional inflation system can not with Quick-pressing cabin pressure change adjust automatically, exist by
Occur crush injury in the too small diver of air demand and the excessive quick safety such as diving dress balloon rupture of escaping danger of drowned or air demand is hidden
Suffer from.How to enable the air demand of inflation system with the pressure change adjust automatically in Quick-pressing cabin, to eliminate safe hidden trouble, be
One important subject of this area.

Brief description of the drawings
Fig. 1 is the structure chart of ventilating control valve.
Fig. 2 is Fig. 1 I portions enlarged drawing.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structure chart of ventilating control valve.
Control valve 102 includes：Valve casing 111, valve seat 112, control valve rod 113, spring base 114, control spring 115, sleeve
116th, interior rigid body 117, diaphragm 118, outer rigid body 119 and valve stem nut 120.
Valve casing 111 is connected and composed by housing 121 and side cover 122 by screw assembly 123.Housing 121 has inlet channel
151st, compensated cavity 152 and outlet passageway 153.
Diaphragm 118 is arranged between housing 121 and side cover 122, is also isolated compensated cavity 152 and feedback cavity 154.Interior rigidity
Body 117 and outer rigid body 119 are separately positioned on the both sides of diaphragm 118.
Fig. 2 is Fig. 1 I portions enlarged drawing.
As shown in Fig. 2 valve seat 120 has a center stepped hole 120-1 and 6 side opening 120-2.Valve seat 120 is arranged on
Between the inlet channel 151 and outlet passageway 153 of housing 110.Center stepped hole 120-1 is communicated with inlet channel 151,6 sides
Hole 120-2 is communicated with outlet passageway 153.The circumference of valve seat 120 and housing 121 is sealed using sealing ring 163, it is ensured that each gas
Sealing between passage and cavity.
Spring base 114 is fixed by the housing 121 of screw assembly 124 and valve casing 111, and the circumference of spring base 114 is using close
Seal 164 is sealed.The one end for controlling valve rod 113 is taper, is matched with the center stepped hole 120-1 of valve seat 120；The other end is worn
The centre bore of spring base 114 is crossed, then sequentially passes through sleeve 116, interior rigid body 117, diaphragm 118, the centre bore of outer rigid body 119
Afterwards, it is threadedly coupled with valve stem nut 120.The two seals circle provided circumferentially about of valve rod 113 is controlled to ensure sealing.Spring
Seat 114 is arranged between spring base 114 and interior rigid body 117.
Sealed between housing 121 and valve seat 112, inlet channel 151 and outlet passageway 153 are split.Control valve rod 113 with
Sealed between spring base 114, compensated cavity 152 is isolated with inlet channel 151, outlet passageway 153.Control valve rod 113 and diaphragm
Sealed between 118, compensated cavity 152 is isolated with feedback cavity 154.
The admission controller operation principle of ventilating control valve：Charge air conditioning enters in housing 121 from inlet channel 151, leads to
The gap crossed between valve seat 112 and control valve rod 113, enters from the center stepped hole 120-1 of valve seat 112, then from side opening 120-2
Outflow, finally flows out from outlet passageway 153.
