Embodiment
In the piston reciprocating compressor in non-clearance type, in order to ensure the structure of its " no clearance ", the suction means that adopts is the downflow type structural type that belongs to general usually, yet no way applies mechanically simply.---for the ease of understanding the structural principle of piston reciprocating compressor in non-clearance type, can understand wherein intension with reference to the ZL200410030658.3 patent document.
In order to realize the purpose of foregoing invention, intend adopting following technology:
Intake valve body P of the present invention is an integrated, structurally comprise at least: be arranged on the inverted cone valve gap 2 at piston 1 outer top, and the valve rod body 3 that connects these inverted cone valve gap 2 tapered side constitutes with the spacing footing 4 that is connected this valve rod body 3 and is positioned at piston 1 inner top side; Inverted cone valve gap 2 is in the airtight state that cooperates with the inverted cone valve opening that is arranged on piston 1 outer top, and valve rod body 3 is in the state of being slidingly matched with the straight valve opening that is arranged on piston 1 inner top;
It is characterized in that, also comprise following characteristics:
A. above-mentioned valve rod body 3 is that the resilient support arms by a pair of symmetry forms (replacement), and, on the resilient support arms of this a pair of symmetry, be provided with the spacing footing 4 of a pair of symmetry again respectively, and, be provided with between the spacing footing 4 of this a pair of symmetry spacing L (for example: according to the numerical value of different this spacing L of drawing materials of spacing footing 4 can get valve rod body 3 diameters about 1/3), the inner top that just can pass the straight valve opening on the piston 1 after 4 oppressed closing up and stretch out piston 1 when this a pair of spacing footing, moreover the above-mentioned three who constitutes intake valve body P is the integrated parts that adopted disposal integral molding technology to make.
Can design in advance: when forcing after above-mentioned a pair of spacing footing 4 closes up, the two that makes this close up just in time forms an ellipse (diameter that its major axis just in time is equal to or slightly less than valve rod body 3 gets final product), and, allow it can pass straight valve opening on the piston 1.After, relying on the resilient support arms of the symmetry of this a pair of formation valve rod body 3 to make this a pair of spacing footing 4 open resets, just can make this a pair of spacing footing 4 play position-limiting action, that is: make the slide up and down scope of intake valve body P in the straight valve opening in piston 1 top be subjected to the restriction at piston 1 top at piston 1 inner top.
B. described intake valve body P have drawn from light-duty engineering plastics or the light metal that has drawn from (for example :) with titanium or aluminium or light metal of the two or light-duty alloy material based on this respectively, and, intake valve body P draw materials with piston 1 draw materials or piston 1 on intake valve body P position is set the part draw materials, should take into full account under high-temperature (certainly will make the temperature rise of pressurized gas improve because work compression ratio has been broken through the conventional boundary of prior art qualification) state influences the coefficient of thermal expansion and contraction situation that its body changes, and is as the criterion with the proper functioning that does not influence intake valve body P.---the most appropriate way is that the cheek of under the ambient temperature of high temperature key singly being joined carries out last abrasive machining operation (seeing the explanation in the following last paragraph for details):
For example, above-mentioned hot environment preferably equals to design definite maximum temperature that contracts and reached than the pressurized gas temperature rise that is caused under the operating mode in rated high voltage, even temperature is very high, but, final always can this temperature rise be limited by the Forced water cooling mode as motor car engine,---motor is lighted the temperature rise temperature that the pressurized gas explosion time can reach at its cylinder top be very high.---make " no clearance " the piston reciprocating type type that is in specified limited superelevation work compression ratio normally to work.
The installation and application of intake valve body P:
Be pressed into straight valve opening as long as will be provided with an end of spacing footing 4 in the intake valve body P one-piece element of inverted cone valve gap 2 from piston 1 upper top, stretch out piston 1 next top and rely on the elasticity of a pair of resilient support arms that forms valve rod body 3 to make that this a pair of spacing footing 4 resets up to a pair of spacing footing 4.---this intake valve body P promptly installs.
---the device that spring 5 is set or has other bouncing plate one classes of these spring 5 functions between the spacing footing 4 of described piston 1 next top and a pair of symmetry exposed.
---the vibration elastic frequency when described spring 5 drives intake valve body P should be air-breathing consistent with reciprocal operation frequency that calm the anger with piston 1.Otherwise, the mechanical consumption in the time of might increasing intake valve body P switching operation.
According to general knowledge, the Aided Machine energy storage device that only needs to increase spring 5 one classes assist intake valve body P high-frequency open and close carry out work under the situation, if the switching resonant frequency that spring 5 drives whole intake valve body P equals or the approaching frequency of okperation that requires intake valve body p to open and close at piston 1 top, it is minimum that mechanical energy power consumption when so, intake valve body P opens and closes will reach.---unless the piston 1 of design belongs to back and forth (being common in the high power horizontal type piston reciprocating compressor) of operation of requirement low frequency, perhaps, by experiment, proved the service behaviour that also can obviously not influence this type when not increasing above-mentioned spring 5 (for example: can whether increase to some extent or whether compressor air-discharging efficient the aspect such as reduces to some extent and differentiate) by the power consumption of compressor dragging motor, certainly, just can consider to omit above-mentioned spring 5.
---common grinding (be easy to act as most intake valve body P be installed on the piston 1 after carry out and carry out) is singly joined with piston 1 upper top plane in the bottom plane of described inverted cone valve gap 2 under above-mentioned hot environment, the two belongs to a plane to guarantee this; If the two is not in one plane, then can't realize " no clearance " structure; Certainly, if be ready, do not get rid of the machining way that adopts the highly difficult independent grinding under unified central planning of dispersion yet can accomplish the same requirement in one plane of said two devices.
