Abstract
The utility model discloses a valve cover, its technical scheme main points are: including the body, the body center is equipped with the shaft hole, be equipped with a plurality of counter bores of placing the spring on the body, be equipped with the bar groove of a plurality of confession circulations of air on the body, the edge of body is equipped with the holding ring, holding ring and body fixed connection, and the holding ring is equipped with the protruding portion towards one side that the body is used for connecting the disk seat, it is protruding that the shaft hole position is equipped with the location, bellied height highly equals with the protruding portion, through setting up the holding ring to set up the protruding portion on the holding ring, can limit the motion of valve block like this, thereby the circumstances of dislocation can not appear, and the setting that holding ring and protruding portion height equal can closely link to each other with the disk seat, like this, can can not lead to the fact and reveal so that the cooperation is inseparable, have a very big promotion to the quality of compressor.
Description
Technical field
The utility model relates to a kind of Parts of Compressor, and more particularly, it relates to a kind of valve gap.
Background technique
Valve gap uses together with valve seat, controls air inlet and give vent to anger, between valve gap and valve body, preventing a valve block, by spring, prop up valve block, valve block is arranged between valve gap and valve body, and valve block can move therein, like this, the action completing air inlet and give vent to anger.
And in the using process of current compressor, it is tight that the cooperation between valve gap and valve body and valve block there will be cooperation, sometimes can misplace, thus cause gas leakage, the work of compressor can be affected like this, very large negative effect is caused to the quality of compressor.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of valve gap, and this valve gap can ensure to coordinate closely with valve body, there will not be inconsistent phenomenon, ensures that compressor can effectively run, ensures the quality of compressor.
For achieving the above object, the utility model provides following technological scheme: a kind of valve gap, comprise body, body central position is provided with axis hole, described body is provided with the counterbore of some placement springs, described body is provided with some bar-shaped troughs for air circulation, the edge of described body is provided with positioning ring, described positioning ring is fixedly connected with body, and the side that positioning ring is used for connecting valve seat towards body is provided with protuberance, described axis hole position is provided with positioning convex, and the height of described projection is equal with the height of protuberance.
The utility model is set to further: described projection is provided with positioning hole.
The utility model is set to further: described counterbore is along the evenly circumference distribution of body central axis, and counterbore evenly to be arranged setting in the radial direction along body, and described bar-shaped trough and counterbore interval are arranged.
The utility model is set to further: each described bar-shaped trough is offered around body central axis respectively, and bar-shaped trough is same in the radial direction between two counterbores.
The utility model is set to further: described bar-shaped trough is less than towards the groove width of one end of protuberance on body the groove width that bar-shaped trough deviates from one end of protuberance on body.
Compared with prior art, the utility model is by arranging positioning ring, and protuberance is set on positioning ring, the motion of valve block can be limited like this, thus there will not be the situation of dislocation, and, the setting that positioning ring is equal with protuberance height closely can be connected with valve seat, like this, can make to coordinate closely, can not leakage be caused, have a very large lifting to the quality of compressor.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model embodiment;
Fig. 2 is the sectional view at A-A place in Fig. 1.
Reference character: 1, body; 2, axis hole; 3, protruding; 4, positioning ring; 41, protuberance; 5, counterbore; 6, bar-shaped trough; 7, positioning hole.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model valve gap embodiment is described further.
As shown in Figure 1 to Figure 2, a kind of valve gap, comprise body 1, in the central position of body 1, axis hole 2 is set, axis hole 2 is for connecting valve seat, body 1 is provided with the counterbore 5 of some placement springs, counterbore 5 is uniformly distributed along body 1 central axis, and, counterbore 5 is uniformly distributed setting in the radial direction along body 1, being evenly distributed of spring can be made like this, thus the elastic force making valve block be subject to is evenly distributed, can prevent valve block from leaking gas like this, compressor operating is caused to go wrong, body 1 is also provided with some for the bar-shaped trough 6 for air circulation, each bar-shaped trough 6 is offered around the central axis of body 1 respectively, and interval is arranged between bar-shaped trough 6 and counterbore 5, and counterbore 5 is positioned between two bar-shaped trough 6 different-diameters (bar-shaped trough 6 around two different-diameters are offered), each bar-shaped trough 6 is offered around body 1 central axis respectively, and bar-shaped trough 6 is same in the radial direction between two counterbores 5, air-flow and elastic force are uniformly distributed, valve plate movement rule can be ensured like this, thus there will not be the situation of dislocation, the edge of simultaneously body 1 is also provided with positioning ring 4, positioning ring 4 is fixedly connected with body 1, and positioning ring 4 is provided with protuberance 41 towards body 1 for the side of connecting valve seat, axis hole 2 position is provided with positioning convex 3, the height of protruding 3 is equal with the height of protuberance 41, the setting that positioning ring 4 is highly equal with protuberance 41 closely can be connected with valve seat, like this, can make to coordinate closely, leakage can not be caused, a very large lifting is had to the quality of compressor.
Preferably, protruding 3 are provided with positioning hole 7, coordinated with valve seat by positioning hole 7, the dislocation of valve seat and valve gap can be prevented like this, ensure sealing, in addition, bar-shaped trough 6 is less than towards the groove width of one end of protuberance 41 on body 1 groove width that bar-shaped trough 6 deviates from one end of protuberance 41 on body 1, make air-flow effectively to pass in and out like this, and the bar-shaped trough 6 of this structure is is easily opened and closed by valve block.
Preferably, the thickness of positioning ring 4 and the height of protuberance 41 and equal with the thickness of body 1 setting.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
