Below with reference to the accompanying drawings the delivery valve seat 100 of compressor according to this utility model embodiment is described in detail.
As depicted in figs. 1 and 2, may include that valve seat body 10 He according to the delivery valve seat 100 of this utility model embodiment
Grading structure 20, valve seat body 10 is provided with groove 11, is provided through the steam vent of valve seat body 10 in groove 11
12.Alternatively, as it is shown in figure 1, be provided with dead eye 30 on delivery valve seat 100, steam vent 12 can neighbouring dead eye
30 are arranged.So so that delivery valve seat 100 reasonable structural arrangement, structural strength is preferable, can extend delivery valve seat 100
Service life.
Grading structure 20 is arranged in valve seat body 10, and grading structure 20 is connected with groove 11, and grading structure 20 is configured to
Tilt to extend to guide from the coolant of steam vent 12 discharge along grading structure 20 from bottom to top and to the direction away from steam vent 12
Flowing.It is understood that after gases at high pressure leave steam vent 12, grading structure 20 can guide gases at high pressure along
Its Surface runoff, such that it is able to avoid the generation of turbulent flow, can reduce flow noise and the flow losses of gases at high pressure, permissible
The flowing smoothness of raising gases at high pressure, and then the noise of compressor can be reduced, the efficiency of compressor can be improved.
According to a preferred embodiment of the present utility model, as it is shown in figure 1, grading structure 20 can include multiple stage portion 21,
Multiple stage portion 21 from bottom to top and are arranged successively to the direction away from steam vent 12.So when gases at high pressure are from steam vent 12
After discharge, gases at high pressure first contact with the stage portion 21 being positioned at downside, and stage portion 21 can change the flow direction of gases at high pressure
And guide gases at high pressure stage portion 21 above it to flow, such that it is able to avoid the generation of turbulent flow, gases at high pressure can be reduced
Flow losses.Alternatively, multiple stage portion 21 can in the vertical direction equivalently-sized.Thus, grading structure 20
Simple and easily fabricated, such that it is able to reduce the production difficulty of delivery valve seat 100, the production of delivery valve seat 100 can be reduced
Cost.Preferably, as it is shown in figure 1, stage portion 21 can be configured to arc.The stage portion 21 of arc can preferably be drawn
Lead gases at high pressure flowing, such that it is able to reduce the flow losses of gases at high pressure, the efficiency of compressor can be improved.
According to a specific embodiment of the present utility model, as it is shown in figure 1, be provided with dead eye 30 on delivery valve seat 100,
Outwards doing ray centered by the center of circle of dead eye 30, the point tangent with ray being positioned at outermost stage portion 21 is base
Point, the center of circle of steam vent 12 and basic point are connected together to auxiliary straight line L1, wherein, the equal position of center of circle O of multiple stage portion 21
Outside in auxiliary straight line L1.As it is shown in figure 1, the line of the center of circle O of multiple stage portion 21 constitutes trajectory L2, track
The part being provided with center of circle O of line L2 is positioned at the outside of auxiliary straight line L1.Thus, grading structure 20 arranges rationally, permissible
It is easy to the flowing of gases at high pressure, the generation of turbulent flow can be avoided, the flow losses of gases at high pressure can be reduced.
