Abstract
The utility model relates to an air valve, in particular to the air valve for a compressor. In order to solve the problem that the clearance of a piston compressor is enlarged because the air valve has an unreasonable structural design, the step of the air valve is shorter and the tail part of an air valve bolt is parallel and level with the bottom part of the step of the air valve, the utility model provides the improved air valve for the compressor. The air valve for the compressor comprises a valve body and the air valve bolt, wherein the valve body is located in the air valve hole of the compressor and comprises an upper valve body, a main valve body and a lower valve body; the air valve bolt is used for assembling the upper valve body, the main valve body and the lower valve body; a reserved channel is formed between the lower bottom surface of the lower valve body and the bottom surface of the air valve hole of the compressor; the lower valve body is lengthened to the height of the reserved channel, and the height of the reserved channel is controlled to be 1.5mm; the tail part of the air valve bolt extends out of the lower bottom surface of the lower valve body, i.e. the tail part of the air valve bolt is inserted into the reversed channel; and the part of the tail part of the air valve bolt, which is inserted into the reserved channel, is a cone. The air valve for the compressor is made of carbon steel so as to ensure the safe operation of the piston compressor. Through improving the air valve for the piston compressor, the clearance is effectively reduced, and the displacement of the piston compressor is more obviously increased.
Description
Technical field
The utility model relates to a kind of air valve, is specially a kind of compressor air valve.
Background technique
Piston compressor is the common equipment in the production of chemical fertilizer, and air valve is a critical piece of piston compressor, its quality directly influences air displacement, power consumpiton and the maintainability of piston compressor, and wherein the channel volume size of air valve body design directly has influence on the efficient of whole piston compressor.Be referred to as the clearance of piston compressor below the volume between the channel volume of air valve and piston stop and the cylinder end caps, the existence of clearance volume has directly reduced the air displacement and the gettering quantity of piston compressor, gas in the clearance volume is along with the to-and-fro motion of piston in addition, the time and expand, the time and be compressed, piston compressor need constantly done idle work to this portion gas, in a word, clearance volume is influential to the throughput and the efficient of piston compressor, clearance volume is crossed throughput and the efficient that conference makes compressor and is sharply descended, but the danger that too small meeting increase piston of clearance volume and cylinder end piece collide, in order to improve the efficient of piston compressor, normally guaranteeing under the safe prerequisite, each position clearance of piston compressor is reduced to minimum, brings up to the efficient of piston compressor the highest.
Existing compressor air valve, comprise the valve body that is positioned at the compressor valve hole, valve body is divided into upper valve body, main valve body, following valve body, the three is assembled as a whole by the air valve bolt, when air valve is packed the air valve hole into, reserved passageway is formed on the bottom surface of following valve body and bottom, air valve hole, and this is the part of clearance.By analysis, cause the bigger factor of clearance control of air valve that several aspects are arranged: 1. because of valve body is shorter down, the reserved passageway height is greatly between 5-10mm; 2. the air valve bolt tail is concordant with following valve body bottom, because the unreasonable clearance volume that causes of above-mentioned air valve structure design increases, has a strong impact on the working efficiency of piston compressor.
Summary of the invention
The utility model, comprises that down valve body is short and the air valve bolt tail is concordant bottom following valve body, and causes the problem of the clearance increase of piston compressor because air valve structure design unreasonable for solving, a kind of compressor air valve of transformation is provided.
For achieving the above object, the utility model is by the following technical solutions: a kind of compressor air valve, comprise and be positioned at the compressor valve hole and by upper valve body, main valve body, the valve body that constitutes of valve body and fit on valve body, main valve body, the air valve bolt of valve body down down, form reserved passageway between the bottom surface in the bottom surface of following valve body and compressor valve hole, following valve body adds and grows to the reserved passageway height and be controlled at 1.5mm, the air valve bolt tail stretches out the bottom surface of valve body down, and promptly the air valve bolt tail inserts reserved passageway.
Improved compressor air valve stretches out the bottom surface of valve body down with the air valve bolt tail, also is about to the air valve bolt tail and inserts reserved passageway, occupies the part clearance, has reduced clearance volume; When usually air valve being packed into the air valve hole, the reserved passageway height between 5-10mm, reduces clearance by the valve body that extends down greatly, and this moment, the reserved passageway height was controlled at 1.5mm, be about to clearance and be controlled at 1.5mm, in the purpose of guaranteeing to have realized under the safe prerequisite reducing clearance.
Further, the part that the air valve bolt tail inserts reserved passageway is a cone, to reduce working resistance.
Further, in order to guarantee the safe operation of piston compressor, the compressor air valve is made by carbon steel.
The utility model is by using the transformation of air valve to piston compressor, the air displacement of piston compressor has had apparent in view increase.
Description of drawings
Fig. 1 is the structural representation of compressor described in the utility model with air valve.
Valve body under the 1-among the figure, 2-air valve bolt.
Embodiment
As shown in Figure 1, a kind of compressor air valve, comprise and be positioned at the compressor valve hole and by upper valve body, main valve body, the valve body that constitutes of valve body 1 and fit on valve body, main valve body, the air valve bolt 2 of valve body 1 down down, form reserved passageway between the bottom surface in the bottom surface of following valve body 1 and compressor valve hole, following valve body 1 adds and grows to the reserved passageway height and be controlled at 1.5mm, air valve bolt 2 afterbodys stretch out the bottom surface of valve body 1 down, and promptly air valve bolt 2 afterbodys insert reserved passageway.
Further, the part of air valve bolt 2 afterbodys insertion reserved passageway is a cone.
Further, the compressor air valve is made by carbon steel, to guarantee the safe operation of piston compressor.
