Abstract
The utility model discloses a one-way valve of an electric braking air compressor exhaust port, belonging to a one-way control valve device and applied to an oversize vehicle. The valve core of the one-way valve is provided with a guide block matching with a valve hole, which ensures that the valve core moves under the control of the guide block. The valve core and a valve seat are centered well. The guide block is arranged on the valve core, facing to the inlet end of air current or at the outlet end of the air current on the valve core. The joint surface of the valve core and the valve seat is a taper face or a spherical surface. The one-way valve body and the valve core part are made of high temperature resistant and rust and corrosion resistant stainless steel or copper material so that the one-way valve and the outlet of the air compressor can not deform and erode in high temperature and water vapor working situation and have long service life.
Description
Technical field
The utility model belongs to the one-way control valve device, particularly is applied to the one-way valve of a kind of electrodynamic braking air compressor relief opening of electric vehicle.
Background technique
The single-screw air compressor of selecting permanent magnetic brushless to drive on the fuel cell motor bus is made the braking air compressor, compare with conventional reciprocating formula braking air compressor, have: noise is little with vibrations, operating temperature is low, the permanent magnetic brushless life-span is long, the efficient advantages of higher, guarantee the riding comfort of fuel battery city carriage, demonstrated fully the quiet advantage of fuel cell system.
There is an one-way valve to connect air compressor, catch pot and oil cut-off valve (as shown in Figure 1) respectively in the single-screw air compressor outlet port that this permanent magnetic brushless drives, be used for stoping high-pressure air refluence the making the return trip empty press in the catch pot, usually the spool in the one-way valve is a plane spool (shown in Fig. 2 b) that does not have guiding, but, show in the use that this structure can not reliably guarantee valve cuts out tightly, after using very short a period of time, the air compressor import will spray mist of oil.At above defective and the application of suitable electric vehicle better, the utility model proposes a kind of check valve apparatus that is suitable for the automobile-used single-screw air compressor of motorized outlet port.
The model utility content
The purpose of this utility model is can not reliably guarantee valve cuts out tightly at conventional planar shape one-way valve in the prior art, after using very short a period of time, the air compressor import will spray the deficiency of mist of oil and propose a kind of one-way valve of electrodynamic braking air compressor relief opening, it is characterized in that, a guide pad that matches with valve body hole is arranged on the spool of described one-way valve, this guide pad is arranged on the entrance point that faces toward air-flow on the spool, or guide pad is arranged on the outlet end that is positioned at air-flow on the spool.
Described guide pad is cross or porous shape, and the exterior edge face of each cross projection is the part of same periphery, and matches with valve body hole.
The engaging surface of described spool and valve seat is conical surface or sphere.
Described one-way valve valve body and spool part adopt stainless steel or copper product high temperature resistant and anti-rust corrosion to make.
The beneficial effects of the utility model are that spool moves under the control of guide pad, make spool and valve seat energy centering good, overcome conventional planar shape one-way valve and can not guarantee reliably to close tight deficiency; The one-way valve part adopts material high temperature resistant and anti-rust corrosion to make, and the assurance one-way valve exports high temperature at air compressor, it is indeformable under the situation of gas flow contact work to contain, do not corrode, and enough life-spans are arranged.
