Abstract
The invention relates to a radial exhaust structure for a rotor compressor, which comprises a cylinder, a dish-shaped valve and a spring, wherein the cylinder is provided with a radial exhaust hole; the dish-shaped valve and the spring are arranged in the exhaust hole of the cylinder; and one end of the dish-shaped valve is arranged on the inner wall of the cylinder in the exhaust hole, and the other end of the dish-shaped valve is sheathed outside the spring. Compared with the prior, the radial exhaust structure for the rotor compressor has the advantages of being simple in structure, good in performance and the like.
Description
Technical field
The present invention relates to a kind of rotor compressor, especially relate to radially exhaust structure of a kind of rotor compressor.
Background technique
The most exhaust structure of existing rotor-type compressor all is to be made of the exhaust seat ring of the DV hole of cylinder, cylinder cap, exhaust valve plate and these parts of exhaust valve plate baffle plate; The clearance volume of this structure is made up of the volume of DV hole and exhaust seat ring.For compressor, it is more little that clearance volume is done, and the performance of compressor just can be done highly more.Therefore, in the face of situation about on the present market high-efficient compressor more and more being paid attention to, refrigeration industry producer is all in the performance of the existing compressor of raising of trying every possible means.The method that reduces clearance volume at present generally is to go from two aspects to consider: one is to reduce the DV pore volume; Another then is the volume that reduces exhaust seat ring.Through years of development, the compressor industry has been a mature industry, and this structure has been improved to optimised form, rethink under this old structure and improve, the amplitude that promotes is very limited, even other integrity problem may occur, loses more than gain on the contrary.Therefore need structure of redesign to solve such problem.
Summary of the invention
Purpose of the present invention is exactly that radially exhaust structure of a kind of simple in structure, rotor compressor that performance is good is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: a kind of rotor compressor is exhaust structure radially, it is characterized in that, this structure is made of cylinder, dish-like valve and spring, described cylinder is provided with rod radial air vent, described disc valve and spring are arranged in the exhaust port of cylinder, disc valve one end is arranged on exhaust port inside cylinder inwall place, and the other end is set in outside the spring.
Described disc valve is the boss shape, is complementary with exhaust port.
The inwall surface of contact sealing of described disc valve and exhaust port.
Described disc valve and exhaust port be sealed into the sealing of plane sealing or hypotenuse.
Described exhaust port is arranged on nearly blade groove place on the cylinder.Described exhaust port is provided with 1-3.
Compared with prior art, the present invention reduces the component number amount that exhaust structure uses by the new radially exhaust structure of design; And cancelled the DV hole, the boss part of dish-like valve has reduced the volume of exhaust passage, thereby can reduce clearance volume, can effectively improve the compressor machine performance like this.

Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
Shown in Fig. 1-2, a kind of rotor compressor is exhaust structure radially, this structure is made of cylinder 1, dish-like valve 2 and spring 3, described cylinder 1 is provided with a rod radial air vent 4, described disc valve 2 and spring 3 are arranged in the exhaust port 4 of cylinder, exhaust port 4 nearly cylinder inner wall places are the boss shape, disc valve 2 one ends are arranged on exhaust port 4 inside cylinders 1 inwall place, disc valve 2 is the boss shape that is complementary with exhaust port herein, disc valve 2 seals with the inwall surface of contact of exhaust port 4, and the other end is set in outside the spring 3.As shown in Figure 4, disc valve 2 is the plane with the surface of contact of exhaust port 4, by this contact plane sealing.
When cylinder 1 sucks gas from suction port 6, when making the pressure that reaches certain in the compression chamber, promote dish-like valve 2 pressure springs 3, this moment, dish-like valve 2 was opened, gas waits exhaust to finish along with exhaust port outwards begins exhaust, and dish-like valve 2 cuts out under the acting in conjunction of spring 3 and pressure reduction again.The shaped design of this dish-like valve 2 should be noted that 2 points: one, the planeness of contact end face must be got well, because this face is used for sealing, if any leaking the cold power performance that then can have influence on complete machine; The 2nd, can design the shape of convex at the head of dish-like valve 2, be used for filling up the clearance chamber, can reduce clearance volume.
Shown in Fig. 1,3, a kind of rotor compressor is exhaust structure radially, this structure is made of cylinder 1, dish-like valve 2 and spring 3, described cylinder 1 is provided with two rod radial air vents 4, described disc valve 2 and spring 3 are arranged in the exhaust port 4 of cylinder, exhaust port 4 nearly cylinder inner wall places are the boss shape, disc valve 2 one ends are arranged on exhaust port 4 inside cylinders 1 inwall place, disc valve 2 is the boss shape that is complementary with exhaust port herein, disc valve 2 seals with the inwall surface of contact of exhaust port 4, and the other end is set in outside the spring 3.As shown in Figure 5, disc valve 2 is a hypotenuse with the contacting point of exhaust port 4, by this contact hypotenuse sealing.
When cylinder 1 sucks gas from suction port 6, when making the pressure that reaches certain in the compression chamber, promote dish-like valve 2 pressure springs 3, this moment, dish-like valve 2 was opened, gas waits exhaust to finish along with exhaust port outwards begins exhaust, and dish-like valve 2 cuts out under the acting in conjunction of spring 3 and pressure reduction again.The shaped design of this dish-like valve 2 should be noted that 2 points: one, the sealing of the exhaust port step of the contact inclined-plane of dish-like valve 2 and cylinder 1 must will be got well, if any leaking the cold power performance that then can have influence on complete machine; The 2nd, can design the shape of convex at the head of dish-like valve 2, be used for filling up the clearance chamber, can reduce clearance volume.
In vent design, the angle of considering exhaust port is bigger than DV hole, can reduce compression stroke, therefore can make single hole (as shown in Figure 2) exhaust into diplopore exhaust (as shown in Figure 3), the gross area that guarantees exhaust port is constant, reduces the exhaust aperture as far as possible, and considers the position of exhaust port is offset toward the direction of blade groove 5 as far as possible, increase compression stroke that like this can be suitable improves refrigerating capacity.
A kind of rotor compressor is exhaust structure radially, this structure is made of cylinder, dish-like valve and spring, described cylinder is provided with three rod radial air vents, described disc valve and spring are arranged in the exhaust port of cylinder, and disc valve one end is arranged on exhaust port inside cylinder inwall place, and disc valve is the boss shape, be complementary with exhaust port, the inwall surface of contact sealing of disc valve and exhaust port, the other end is set in outside the spring, and exhaust port is arranged on nearly blade groove place on the cylinder.
