Description
Technical field
This utility model is related to a kind of suction valve chip, more particularly to a kind of exhaust resistance is little, can increase compressor useful work,
Improve the frequency-changeable compressor suction valve chip of refrigerating efficiency.
Background technology
Compressor is the heart of refrigeration plant, and wherein refrigerating efficiency is one of key index of compressor, how to improve pressure
The Energy Efficiency Ratio (reducing energy consumption improves refrigeration performance) of contracting machine, that is, the idle work reduced in compressor operating is that people are pursued
One of target.Start from the improvement of related components to set about for this people, including the exhaust resistance for reducing suction valve chip,
Existing method is generally by special suction valve chip material, or the thickness of suction valve chip tongue comes in reduction suction valve chip
Reduce exhaust resistance, but because suction valve chip tongue and suction valve chip generally adopt same material integration stamped molded, and can
The material price for reducing exhaust resistance is expensive, and production cost can be greatly improved, and reduces suction valve chip tongue in suction valve chip
During thickness, because suction valve chip tongue needs certain bonding strength, simple suction valve chip and the thickness of suction valve chip tongue
What reduction can not take into account solves the above problems.
The content of the invention
This utility model is mainly little there is provided a kind of exhaust resistance, can save manufacturing cost, increases compressor useful work,
The frequency-changeable compressor suction valve chip of refrigerating efficiency is improved, reduction compressor air-discharging resistance cost present in prior art is solved
Height, causes compressor useful work to reduce, the low technical problem of refrigerating efficiency.
What above-mentioned technical problem of the present utility model was mainly addressed by following technical proposals：A kind of frequency conversion compression
Machine suction valve chip, including square valve block body and the inlet valve tongue hole on valve block body, on inlet valve tongue hole
Again insertion is connected to steam vent, and horizontally toward extension forms inlet valve in inlet valve tongue hole for the side edge in inlet valve tongue hole
Tongue, forms gap between the periphery of inlet valve tongue and corresponding inlet valve tongue hole, the thickness of the inlet valve tongue is from it
Outwards gradually successively decrease with the junction in inlet valve tongue hole.By change inlet valve tongue thickness, and make its from junction to
When gradually successively decreasing outward, you can the elasticity of inlet valve tongue is greatly improved on the basis of original material is not changed, so as to reduce row
Atmidometer, simultaneously because its junction thickness keeps constant, therefore also ensure that the bonding strength of inlet valve tongue, manufacturing cost
It is low, the useful work of compressor is increased, improve refrigerating efficiency.
Preferably, the inlet valve tongue thickness being connected with the inlet valve tongue hole is 0.173mm, inlet valve tongue hole
Outboard end thickness be 0.1mm, and the thickness even transition in inlet valve tongue hole.Inlet valve tongue keeps rational thickness, both
Bonding strength is can guarantee that, elasticity can be improved again, reduce exhaust resistance.
Preferably, the inlet valve tongue is connected to the rectangle basilingual at inlet valve tongue hole edge, square including integral type
The front end of shape basilingual is horizontal forward to extend inwardly to form First Transition connection tongue, the front end of First Transition connection tongue it is horizontal forward to
Outer extension forms the second transition connection tongue, and again horizontal forward extension forms circular tongue to the second transition connection tongue, and rectangle basilingual,
The edge of First Transition connection tongue, the second transition connection tongue and circular tongue and formation between corresponding inlet valve tongue hole inwall
Gap is gradually reduced.According to correlation theory, the width in frequency-changeable compressor suction valve chip tongue gap directly affects compression intracavity
Residual refrigerant storage, it is more that wider tongue gap retains the residual refrigerant amount of compression intracavity, causes and increased
The idle work of compressor, so that refrigerating efficiency is low.By rectangle basilingual, First Transition connection tongue, the second transition connection tongue and
Circular tongue integral type connects to form the inlet valve tongue that two middle side parts cave inward, and inlet valve tongue keeps with valve block body again
Integral type connects, and simple structure had both met the aeroelastic requirements of inlet valve tongue, and in turn ensure that its bonding strength, by changing
Four parts of composition inlet valve tongue and the gap in corresponding inlet valve tongue hole, make each intersegmental gap keep unequal distribution, and
Gap is gradually reduced, groundwork position of the circular tongue therein as inlet valve tongue, it is ensured that its gap minimizes
Maximizing increases compressor useful work, improves refrigerating efficiency, and when suitably increasing the gap at other positions, life can be greatly lowered
Cost is produced, makes to keep rationalizing between suction valve chip performance indications and manufacturing cost.
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 frequency-changeable compressor suction valve chip tool of the present utility model has the advantage that：By changing air-breathing clack valve
The thickness of spring, and when making it outwards gradually successively decrease from junction, you can suction is greatly improved on the basis of original material is not changed
The elasticity of air valve tongue, so as to reduce exhaust resistance, simultaneously because its junction thickness keeps constant, therefore also ensure that air-breathing
The bonding strength of clack valve spring, low cost of manufacture increased the useful work of compressor, improve refrigerating efficiency；Before inlet valve tongue
The circular tongue at end keeps minimum clearance, and the rectangle basilingual gap of rear end is maximum, you can meeting suction valve chip performance
Meanwhile, production cost is reduced by adjusting each section of clearance distance, and increase compressor useful work, improve refrigerating efficiency.
