Production cost, and increase compressor useful work, improve refrigerating efficiency.
Preferably, the gap between the rectangle basilingual both sides and corresponding inlet valve tongue hole inwall be 0.5mm extremely
0.8mm, the gap between the second transition connection tongue and corresponding inlet valve tongue hole inwall be the mm of 0.7mm to 0.5, First Transition
Gap between connection tongue and corresponding inlet valve tongue hole inwall is the mm of 0.4mm to 0.2, circular tongue and corresponding inlet valve
Gap between the inwall of tongue hole is the mm of 0.3mm to 0.1.Groundwork position of the circular tongue as inlet valve tongue, it is ensured that its
Gap minimum is that maximizing increases compressor useful work, improves refrigerating efficiency, and when suitably increasing the gap at other positions,
Production cost can be greatly lowered, makes to keep rationalizing between suction valve chip performance indications and manufacturing cost.
Preferably, the edge of the rectangle basilingual, First Transition connection tongue, the second transition connection tongue and circular tongue with
The gap formed between corresponding inlet valve tongue hole inwall is gradually reduced.It is true according to the work characteristics at each position of inlet valve tongue
The circular tongue of fixed gap, i.e. front end keeps minimum clearance, so as to increase compressor useful work, improves the same of refrigerating efficiency
When, make manufacturing cost realize minimumization.
Preferably, keeping light between the rectangle basilingual, First Transition connection tongue, the second transition connection tongue and circular tongue
Slip over and cross connection.When holding smoothly transits and connects between each composition position of inlet valve tongue, it is ensured that the entirety of inlet valve tongue
Bonding strength and service behaviour.
Preferably, the steam vent insertion is connected between First Transition connection tongue and the second transition connection tongue.
Preferably, the rectangle basilingual and valve block body junction are respectively provided on two sides with long arc shape transitional pore, long arc
Shape transitional pore insertion is connected on the corresponding gap in rectangle basilingual both sides and carries over the extending direction extension in gap.Long arc shape transition
Hole can effectively reduce inlet valve tongue connecting portion shearing force operationally, it is to avoid be produced using rear junction for a long time disconnected
Split.
Therefore, a kind of compressor air suction valve block tool of the present utility model has the advantage that：According to each portion of inlet valve tongue
The work characteristics of position determines gap, makes each intersegmental gap keep the circular tongue of rational unequal distribution, front end to keep minimum clearance,
The rectangle basilingual gap of rear end is maximum, you can while suction valve chip performance is met, by the clearance gap for adjusting each section
From reducing production cost, and increase compressor useful work, improve refrigerating efficiency；The long arc shape of rectangle basilingual junction
Transitional pore can effectively reduce inlet valve tongue connecting portion shearing force operationally, it is to avoid be produced using rear junction for a long time
Fracture, extends the service life of suction valve chip.
