Abstract
The utility model relates to a gas compressor part, in particular to a device for eliminating the pressure pulsation, which comprises a gasket arranged between contact flanges. The inside diameter of the gasket is less than the diameter of a pipeline; the inner wall of the gasket is provided with an inner wing plate; the inner hole diameter of the inner wing plate is less than the diameter of the pipeline; the gasket is shaped as a ring, the circumference of the gasket is provided with a convex ring connected with the flanges by a sealing way, and the inner wing plate is connected with the convex ring; the gasket is shaped as a ring, the axial section of the edge of the gasket is shaped as an ellipse, and the elliptical edge of the gasket is connected with the flanges by the sealing way; an elliptical long shaft is more than the plate thickness of the inner wing plate; and a transition corner is arranged between the inner wing plate and the gasket. The utility model removes the structure of a plurality of connecting faces of the gasket and a pore plate in the traditional device, organically combines the pore plate and the gasket together, reduces the sealing face, lowers the leakage probability, is especially suitable for occasions with high pressure grade, shortens the distance between the contact flanges, reduces the connecting size, and saves the space.
Description
Technical field
The utility model relates to the gas compressor parts, specifically a kind of device of eliminating pressure pulsation.
Background technique
Compressor is the machinery that gas pressure is improved, and compressor is when work, because the intermittent type suction and discharge of piston make the fluid in its pipeline present pressure pulsation.In order to eliminate the pressure pulsation of pipeline inner fluid, a device need be set between the pipeline flange connecting.Conventional device comprises a slicing orifice plate and two pads.The slicing orifice structure is that band endoporus, a thickness are the circular sheet of 3～5mm, when flange connects, is connected with flange seal by pad respectively in the both sides of orifice plate.As Fig. 1, shown in Figure 3, be evenly equipped with through hole on the circumference of orifice plate 2, the axial cross section of pad 3 is oval, between the both sides and flange 1 of orifice plate 2; The double-screw bolt that is used to connect two flanges is passed by through hole.As Fig. 2, shown in Figure 4, be spiral wound gasket; The diameter of bore of above-mentioned pad is all greater than pipeline diameter.Adopt the device of above-mentioned two kinds of structures, when flange connected, two faces of orifice plate all will be connected with flange by pad, have increased the quantity of junction surface, and then had increased the quantity of the face of revealing, and caused the sealing surface of physical dimension to lose efficacy easily; In addition, owing between adpting flange, be provided with an orifice plate and two pads, increased Conncetion cimension, not only having increased needs ccontaining space, cause the unstability of structure to strengthen, also make the screw sizes of adpting flange increase, and be unfavorable for moving the scene rectification of pipeline.
The model utility content
Easily reveal in order to solve the prior art aperture plate, lost efficacy easily, the problem of poor stability, the purpose of this utility model is to provide a kind of improvement linkage structure, reduces the device that sealing surface destroys the elimination pressure pulsation of revealing.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises the pad that is arranged between the adpting flange, and the internal diameter of this pad is less than the diameter of pipeline.
Wherein: the inwall of described pad is provided with interior wing plate; The internal orifice dimension of interior wing plate is less than the diameter of pipeline; Described pad is an annular, is provided with the protruding ring that is connected with flange seal on the circumference of pad, and interior wing plate is connected with protruding ring; Described pad is an annular, and the axial cross section at its edge is oval, and the oval rim of pad is connected with flange seal; Oval-shaped major axis is greater than the thickness of slab of interior wing plate; Be knuckle between wing plate and the pad in described; The internal diameter of described pad is 0.4～0.5 times a pipe diameter.
Advantage of the present invention and good effect are:
1. the utility model has been cancelled the structure of multi-link of conventional apparatus aperture plate and pad, and orifice plate and pad organically are combined in one, has reduced sealing surface, has reduced the leakage possibility, is particularly useful for the occasion of high pressure grade.
2. shorten the distance between the adpting flange, reduced Conncetion cimension, saved the space.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Orifice plate and pad that the utility model device will play the slicing effect organically combine, and form the gasket type orifice plate.Device comprises the pad 3 that is arranged between the adpting flange 1, and the inwall of pad 3 is provided with interior wing plate 4; The internal orifice dimension of interior wing plate 4 is 0.4～0.5 times a pipe diameter.
Embodiment 1 (air ring)
As Fig. 5, Fig. 6 and shown in Figure 9, pad 3 is an annular, and the axial cross section at its edge is oval, and the oval rim of pad 3 and flange 1 are tightly connected; Oval-shaped major axis is greater than the thickness of slab of interior wing plate 4.Be knuckle 6 between interior wing plate 4 and the pad 3.
Embodiment 2 (metal wound gasket)
As Fig. 7, Fig. 8 and shown in Figure 10, pad 3 is an annular, is provided with the protruding ring 5 that is tightly connected with flange 1 on the circumference of pad 3, and interior wing plate 4 is connected with protruding ring 5.
