Abstract
The utility model relates to a connecting flexible pipe of an internal and an external apparatus sets of a separated refrigerating system. The aim of the utility model is to provide the connecting flexible pipe of an internal and external apparatus set of a separated refrigerating system having the advantage of low cost, and the connecting flexible pipe of an internal and external apparatus set of a separated refrigerating system can solve a noise problem. The utility model is characterized in that a cylindrical spiral spring of which the free length is equal to the length of a pipe body of a metal spiral flexible pipe is arranged in the pipe body of the metal spiral flexible pipe for connecting the internal and the external apparatus sets of the existing split refrigerating system. The pitch length of the cylindrical spiral spring is identical to the pitch length of the metal spiral flexible pipe, the outer diameter is lightly smaller than the maximum inner diameter of the metal spiral flexible pipe and the inner diameter is approximately corresponding to the minimum inner diameter of the metal spiral flexible pipe. Due to the adoption of the technical scheme, a spiral slot space formed by the inner wall of the metal spiral flexible pipe is filled in the spring body part of the cylindrical spiral spring; when the mixture of the refrigerant of a gas-liquid phase flows, the condition of noise generation is destroyed. The utility model solves the noise problem, and has low cost.
Description
(1) technical field:
The utility model relates to a kind of connecting tube, particularly relates to the inside and outside unit of a kind of split type refrigeration system and connects flexible pipe.
(2) background technique:
Inside and outside unit connecting tube tradition is used copper pipe in the split type refrigeration system, because copper pipe exists easily by the flat shortcoming of folding, the metal spiral flexible pipe is used in a large number as the connecting tube of unit inside and outside the split type refrigeration system in the prior art, this metal spiral flexible pipe is made up of corrugated hose body, the connecting head that is connected in the body two ends, the Stainless Steel Wire mesh grid that is wrapped in outside the body, during the work of split type refrigeration system, gas-liquid phase refrigerant mixed body in the metal spiral flexible pipe along the helix direction flow at high speed.There is following deficiency in this technology: when the split type refrigeration system startup work initial stage, because the inner diameter values cyclically-varying of metal spiral flexible pipe, gas-liquid phase refrigerant mixed height speed produces the noise of certain frequency when flowing, need to be resolved hurrily.For this reason, there is the people to be built-in with the constant plastic flexible pipe of internal diameter that an external diameter value is slightly less than metal spiral flexible pipe minimum diameter value, allows gas-liquid phase refrigerant mixed body flow at the constant plastic flexible pipe of internal diameter at the metal spiral flexible pipe.This technological scheme has solved noise problem, but cost is higher.
(3) summary of the invention:
The utility model aims to provide a kind of low cost and can solve the inside and outside unit connection of the split type refrigeration system flexible pipe of noise problem.
Technical solution of the present utility model is as follows:
The inside and outside unit of a kind of split type refrigeration system connects flexible pipe, it is by the metal spiral hose body, be connected in the connecting head at body two ends, being wrapped in the outer Stainless Steel Wire mesh grid of body forms, the inner diameter values of described corrugated hose body is periodic variation with pipe range, the difference DELTA d of its maximum inner diameter and minimum diameter is a definite value, it is characterized in that: it comprises that also one places in the metal spiral flexible pipe and its free length and the isometric cylindrical helical spring of metal spiral hose body, the pitch of described cylindrical helical spring is identical with the pitch of metal spiral flexible pipe, its external diameter value is slightly less than its maximum inner diameter value of metal spiral flexible pipe, and the minimum diameter value of its inner diameter values and metal spiral flexible pipe is roughly suitable.
The utility model is owing to adopt technique scheme, and the spring body portion of cylindrical helical spring has been filled up the formed spiral chute of metal spiral hose inner wall space, and the condition that produces noise when gas-liquid phase refrigerant mixed body flows is destroyed, and has solved noise problem.Its cost is lower simultaneously.
Further technical solution is:
The described inner diameter values of the cylindrical helical spring in the metal spiral flexible pipe that places equates with the minimum diameter value of metal spiral flexible pipe.
The better effects if of the solution noise of further technical solution.
(4) description of drawings:
Below with reference to drawings and Examples the utility model is described in further details:
Accompanying drawing 1 is the utility model embodiment 1 a structural representation.
Each sequence number is respectively in the accompanying drawing 1: 1, connecting head; 2, Stainless Steel Wire mesh grid; 3, cylindrical helical spring; 4, metal spiral hose body
(5) embodiment:
Referring to accompanying drawing 1, the utility model embodiment 1 comprises metal spiral hose body 4, be connected in the connecting head 1 at body two ends, be wrapped in the outer Stainless Steel Wire mesh grid 2 of body, the inner diameter values of described metal spiral hose body is rendered as periodic variation with pipe range, the difference DELTA d of its maximum inner diameter and minimum diameter is a definite value, it comprises that also one places in the metal spiral flexible pipe 1 and its free length and the isometric cylindrical helical spring 3 of metal spiral hose body, the pitch of described cylindrical helical spring 3 is identical with the pitch of metal spiral hose body 4, its external diameter value is slightly less than the maximum inner diameter value of metal spiral hose body 4, and its inner diameter values is slightly larger than the minimum diameter value of metal spiral flexible pipe 4.
The utility model cost is low and solved noise problem.
Claims (2)
1, the inside and outside unit of a kind of split type refrigeration system connects flexible pipe, it comprises the metal spiral hose body, be connected in the connecting head at body two ends, be wrapped in the outer Stainless Steel Wire mesh grid of body, the inner diameter values of described corrugated hose body is periodic variation with pipe range, the difference DELTA d of its maximum inner diameter and minimum diameter is a definite value, it is characterized in that: it comprises that also one places in the metal spiral flexible pipe and its free length and the isometric cylindrical helical spring of metal spiral hose body, the pitch of described cylindrical helical spring is identical with the pitch of metal spiral flexible pipe, its external diameter value is slightly less than its maximum inner diameter value of metal spiral flexible pipe, and the minimum diameter value of its inner diameter values and metal spiral flexible pipe is roughly suitable.
2, the inside and outside unit of split type refrigeration system according to claim 1 connects flexible pipe, it is characterized in that: the described inner diameter values of the cylindrical helical spring in the metal spiral flexible pipe that places equates with the minimum diameter value of metal spiral flexible pipe.
