Description
Technical Field
The utility model relates to the technical field of silencing bag assemblies, in particular to an air inlet pipe of a silencing bag.
Background
The air conditioner compressor is internally provided with a silencing bag to reduce noise, the middle part of the copper steel silencing bag is made of steel materials, and an air inlet and an air outlet at two ends of the copper steel silencing bag are an air inlet pipe and an air outlet pipe which are made of copper.
The prior air inlet pipe is constructed as a hollow straight rod, the air inlet of the silencing bag and the air inlet of the silencing bag are fixed in a welding or riveting mode after extending into the inner cavity of the silencing bag, for example, a silencer disclosed in patent number 201210041348.6 and an air conditioner comprising the silencer,
and my independent research and development publication number CN112302907B, a sound deadening bag for use on a compressor of an air conditioner.
The two existing silencing bags are not used as air inlet pipes for guiding flow, and the silencing bags can be buffered and silenced preliminarily.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the air inlet pipe which has reasonable and simple structure and strong practicability and can buffer and help the silencing bag to perform primary silencing.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides a amortization package intake pipe, includes the body that is the cavity form, is equipped with the portion of slowly pressing on the exhaust end of body, and the cross-sectional area of portion of slowly pressing is greater than body cross-sectional area, and the output extension of portion of slowly pressing is equipped with the buffering portion, and the cross-sectional area of this buffering portion is the same with the cross-sectional area of body, and the joint has the plectane in the buffering portion, has seted up a plurality of exhaust holes that run through its body on the plectane, and the exhaust hole aperture increases gradually, and each exhaust hole is the slope form and offers.
The utility model is further provided with: the outer peripheral wall of the circular plate is inwards recessed to form an annular groove, and an annular protrusion extruded with the annular groove is arranged on the inner wall of the buffer part.
The utility model is further provided with: the sectional area of the pressure relieving part is 1.5 times of the sectional area of the body.
Compared with the defects in the prior art, the utility model has the beneficial effects that:
through set up pressure relief portion and plectane in with the intake pipe, when the air current gets into pressure relief portion from the body, the air current inflation has consequently led to the production of negative pressure, and the air current plays the effect of buffering to reduce the air current velocity of flow, when the buffer portion that the cross-sectional area is little is passed through, because through the space reduction, the air current can increase its speed of passing through, when the air current passes through the vent that the slope of plectane set up, the flow direction produces turbulent flow effect, avoids the air current to produce the quick flow.
Drawings
FIG. 1 is a cross-sectional view of the present utility model;
FIG. 2 is a schematic view of the structure of the circular plate of the present utility model;
fig. 3 is a schematic cross-sectional view of a circular plate of the present utility model.
The device comprises a body 1, a pressure relief part 11, a buffer part 12, a circular plate 3, an exhaust hole 30, an annular groove 31 and an annular protrusion 121.
Detailed Description
Embodiments of the present utility model will be further described with reference to fig. 1 to 3.
The specific structure of the embodiment is as follows: including being hollow form body 1, be equipped with the portion of slowly pressing 11 on the exhaust end of body 1, the sectional area of portion of slowly pressing 11 is greater than body 1 sectional area, and the sectional area of portion of slowly pressing 11 is 1.5 times of body 1 sectional area, can effectually alleviate the atmospheric pressure that the air current got into portion of slowly pressing 11 from body 1 to reduce the velocity of flow.
The output end of the pressure-relieving part 11 is extended and provided with a buffer part 12, the cross section area of the buffer part 12 is the same as the cross section area of the body 1, a circular plate 3 is clamped in the buffer part 12, a plurality of vent holes 30 penetrating through the body 1 are arranged on the circular plate 3, the aperture of the vent holes 30 is gradually increased, and each vent hole is obliquely arranged along the annular array.
The flow speed of the air flow can be reduced on the pressure-reducing part 11, the flow speed is increased by the buffer part 12, the air flow obviously reduces speed when passing through the air exhaust holes 30 of the circular plate 3, the air exhaust holes 30 are inclined, and turbulence can be generated from different directions when the air flow passes through, so that noise caused by the speed-exciting flow of the air flow is avoided.
The outer peripheral wall of the circular plate 3 is recessed inwards to form an annular groove 31, and an annular protrusion 121 extruded with the annular groove 31 is arranged on the inner wall of the buffer part 12. When the circular plate 3 and the buffer part 12 are installed, the circular plate 3 is extruded from the port of the buffer part 12, then the buffer part 12 is extruded by the oil pressure calipers so that the outer wall of the buffer part is inwards extruded to form an annular bulge, and the annular bulge 121 and the annular groove 31 on the circular plate 3 are extruded to realize clamping and fixing of the circular plate 3 and the buffer part.
The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model, but one skilled in the art can make common changes and substitutions within the scope of the technical solution of the present utility model.
