Abstract
The utility model relates to an oblique-plane sealing valve which comprises a valve seat and a valve cover arranged on the upper end face of the valve seat. The upper end face of the valve seat is provided with a groove, an annular valve plate is arranged in the groove and arranged between the valve seat and the valve cover, the valve seat is provided with a plurality of valve holes I, the valve cover is provided with valve holes II in butting connection with the valve holes I, and the upper end face of the annular valve plate in contact with the valve holes II of the valve cover is the oblique-plane sealing face. The sealing face of the valve body valve plate is designed to be an oblique plane, the obstruction influence of the valve body valve plate to air flow circulation is reduced, and the oblique-plane sealing valve conforms to an air flow circulation characteristic to enable air flows to quickly and smoothly pass through an air valve.
Description
Technical field
The utility model relates to universal machine reciprocal compressor air valve technical field, relates in particular to a kind of inclined-plane seal valve.
Background technique
Thereby universal machine reciprocal compressor is to utilize mechanical energy air to be compressed to the standard equipment that obtains certain pressure air and output supply client use, reciprocal compressor generally comprises valve seat, opens and closes element, elastic element and lift limiter with air valve, its performance directly affects working life and the energy loss of air valve, the gas valve plate sealing surface that traditional compressor is used mostly is burnishing surface, be unfavorable for airflow, slowed down airflow speed, negotiability is poor.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of inclined-plane seal valve is provided, and the sealing surface of valve body valve block is inclined-plane, has strengthened the negotiability of air-flow.
The utility model is achieved through the following technical solutions: a kind of inclined-plane seal valve, comprise valve seat and the valve gap that valve seat upper-end surface is set, described valve seat upper-end surface arranges groove, annular valve block is set in described groove, described annular valve block is arranged between valve seat and valve gap, described valve seat is provided with several valve opening I, and described valve gap is provided with the valve opening II of docking with valve opening I, and it is inclined-plane sealing surface that described annular valve block contacts upper-end surface with the valve opening II of valve gap.
Further, described valve seat and valve gap center are fixed by bolt cross-under.
Further, in described valve seat, be provided with the spring that withstands annular valve block lower end surface.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being designed to inclined-plane by the sealing surface of valve body valve block, reduced the obstruction impact of valve body valve block on airflow, complied with airflow feature, allowed air-flow pass through more smoothly sooner air valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of inclined-plane of the utility model seal valve.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model relates to a kind of inclined-plane seal valve, comprise valve seat 1 and the valve gap 2 that valve seat 1 upper-end surface is set, it is characterized in that, described valve seat 1 upper-end surface arranges groove 9, described groove 9 is interior arranges annular valve block 3, described annular valve block 3 is arranged between valve seat 1 and valve gap 2, described valve seat 1 is provided with several valve opening I 4, described valve gap 2 is provided with the valve opening II 7 of docking with valve opening I 4, it is inclined-plane sealing surface 8 that described annular valve block 3 contacts upper-end surface with the valve opening II 7 of valve gap 2, described valve seat 1 and valve gap 2 centers are fixed by bolt 5 cross-under, in described valve seat 1, be provided with the spring 6 that withstands annular valve block 3 lower end surfaces.
In sum, valve gap 2 of the present utility model plays the effect that rises limiter, annular valve block 3 plays seal action with valve seat 1 laminating, spring 6 opens and closes element, valve block is moved reciprocatingly, bolt 5 supports whole air valve, make elements combination in air valve together, the pressure difference at air valve two ends make annular valve block 3 promote springs 6 by valve seat 1 end to valve gap 2 end motions, air-flow is by the passage of valve seat 1, along with pressure difference changes, make again spring 6 promote annular valve block 3 by valve gap 2 ends to valve seat 1 end motion, air-flow is by the passage of valve gap 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. an inclined-plane seal valve, comprise valve seat and the valve gap that valve seat upper-end surface is set, it is characterized in that, described valve seat upper-end surface arranges groove, annular valve block is set in described groove, and described annular valve block is arranged between valve seat and valve gap, and described valve seat is provided with several valve opening I, described valve gap is provided with the valve opening II of docking with valve opening I, and it is inclined-plane sealing surface that described annular valve block contacts upper-end surface with the valve opening II of valve gap.
2. a kind of inclined-plane according to claim 1 seal valve, is characterized in that, described valve seat 1 and valve gap center are fixed by bolt cross-under.
