Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figures 1 to 6, the present invention provides a kind of compressor valve board, including valve plate body 6, valve plate body 6 is just
Face is provided with groove 1, and gas vent 2 is provided in groove 1, and suction hole 4 is also provided on valve plate body 6, and the contour line of suction hole 4 includes leaning on
First curved section 7 of nearly gas vent 2 and the second curved section 8 far from gas vent 2, the first curved section 7 and the second curved section 8 pass through
Third circular arc 9 and the connection of the 4th circular arc 10, the first curved section 7 and the second curved section 8 are protruded to the direction far from gas vent 2,
First curved section 7 includes the First Transition straightway 71 positioned at middle part, and the second curved section 8 includes that the second transition positioned at middle part is straight
Line segment 81.
The present invention is being inhaled by the way that First Transition straightway 71 is arranged on the first curved section 7 of 4 contour line of valve plate suction hole
The second transitional straight section 81 is set on second curved section 8 of stomata contour line, when 4 air-breathing of suction hole, gas is made to act on suction
Evenly, flexible deformation when reducing 4 stress of suction hole is solved because of the slap formation of suction hole 4 of multiple stress power on stomata 4
The problem of plastic deformation, improves suction valve chip operational reliability.The shape suction hole 4, closer to compresser cylinder cylinder holes center,
Air-breathing is set evenly to improve gettering efficiency.
Preferably, one end of one end of the First Transition straightway 71 on 4 contour line of suction hole and third circular arc 9 passes through the
One subarc line segment 72 connects, and one end of the other end of First Transition straightway 71 and the 4th circular arc 10 passes through the second subarc line segment 73
Connection；One end of second transitional straight section 81 is connect with one end of third circular arc 9 by third subarc line segment 82, and the second transition is straight
The other end of line segment 81 is connect with one end of the 4th circular arc 10 by the 4th subarc line segment 83.I.e. by the first subarc line segment 72,
The transition of second subarc line segment 73, third subarc line segment 82, the 4th subarc line segment 83 reduces the concentration stress of suction hole 4, keeps away
Exempt from stress concentration, make 4 force dispersion of suction hole, reduces the possibility for leading to air-breathing bore deformation because local pressure is excessive.
Further, the first subarc line segment 72 and the second subarc line segment 73 can be co-located on the first circumference, the first mistake
Cross the secant that straightway 71 is the first circumference；Third subarc line segment 82 and the 4th subarc line segment 83 can be co-located at the second circumference
On, the second transitional straight section 81 is the secant of the second circumference.Such structure design, cambered surface transition is more smooth, reduces air-breathing
The concentration stress in hole 4, and be also more convenient when processing.
In conjunction with shown in Fig. 1,4 and Fig. 5, suction hole 4 is provided with water conservancy diversion cambered surface 41 along airflow direction, this water conservancy diversion cambered surface 41 can be with
Reduce inspiratory resistance, then reduces impact of the gas to suction hole.
In conjunction with shown in Fig. 4,5 and Fig. 6, the back side of valve plate body 6 be provided be engaged with inlet valve line it is at least one
Seal line 42, which can be one, can also be a plurality of, general 1 to 2 are advisable.When inlet valve is closed, air-breathing
Valve is engaged with seal line 42, and sealing effect is more preferable.
In conjunction with shown in Fig. 1,2 and Fig. 4, suction hole 4 and gas vent 2 are set to compresser cylinder hole and valve plate body 6 jointly
In corresponding profile, air-flow enters cylinder by suction hole 4, by expansion, compression, then cylinder is discharged by gas vent 2, then
Compressor is discharged by exhaust passage, therefore suction hole 4 will be set to compresser cylinder hole and valve plate body jointly with gas vent 2
In 6 corresponding profiles；Suction hole 4 and gas vent 2 should also be as maintaining a certain distance, to reduce heat exchange loss.
Preferably, venthole 5 is offered on valve plate body 6, venthole 5 is located at the side of suction hole 4 and gas vent 2.It is logical
Stomata 5 is used as interface channel, is connected to discharge chamber and exhaust noise silencing chamber in compressor cylinder cover, reduces in compressor operation
Noise and vibration.
In conjunction with shown in Fig. 1, it is provided with mounting hole 3 on the quadrangle of valve plate body 6, valve plate body 6 is enable to be clamped securely to
Cylinder jacket top.
The present invention also provides a kind of compressor valve components to make suction valve chip stress more using compressor valve board above-mentioned
Uniformly, it is not easy to 4 part metaboly of suction hole occur, improve suction valve chip operational reliability.The shape suction hole 4, is more leaned on
Nearly compresser cylinder cylinder holes center, makes air-breathing evenly improve gettering efficiency.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
