Abstract
The utility model relates to a needle valve fastener which comprises a fastening base. A first through hole is formed in the lower portion of the fastening base, and a second through hole which is perpendicular to the first through hole and communicated with the first through hole is formed in the upper portion of the fastening base. A through first notch and a through second notch are formed in the side edge of the first through hole and the side edge of the second through hole respectively, so that the fastening base is mounted at the joint of a needle valve and a pipeline system copper pipe. An annular groove is formed in the edge of the fastening base, a binding belt can be fastened in the groove, and thus the fastening base is fastened. The needle valve fastener is reasonable in design, simple in structure and convenient to use, through the two through holes in the fastening base, the needle valve can be fixedly connected with the pipeline system copper pipe, the needle valve and the pipeline system copper pipe are fastened through the binding belt, the welding spot fracture phenomenon caused by vibration of the copper pipe of an air-conditioner pipeline system can be effectively avoided, and therefore the operating quality of an air-conditioner is improved.
Description
Technical field
The utility model relates to a kind of air-conditioning parts, especially a kind of fastener for fixing needle-valve, a kind of needle-valve securing member specifically.
Background technology
At present, in air conditioning pipe system, be widely applied to needle-valve.This needle-valve is normally vertically welded on the flanging bore of pipe-line system copper pipe, as shown in Figure 1.In the process of air-conditioning transport or air-conditioning work, pipeline can vibrate, and causes causing the solder joint of needle-valve and pipe-line system copper pipe junction to break, and coolant leakage occurs.If can design a kind of can, by needle-valve and the fastening device of pipeline copper pipe, can effectively avoiding because the solder joint that pipeline vibration causes breaks, improve the running quality of air-conditioning.
Summary of the invention
The purpose of this utility model is to provide a kind of needle-valve securing member, needle-valve can be tightened together with pipe-line system copper pipe, avoids the needle-valve solder joint causing because of pipeline vibration to break.
The technical solution of the utility model is:
A kind of needle-valve securing member, comprises fastening base.The bottom of described fastening base is provided with the first through hole, and top is provided with the second through hole vertical with the first through hole and that communicate; The side of described the first through hole and the second through hole has the first breach and second breach of perforation, makes fastening base can be arranged on the junction of needle-valve and pipe-line system copper pipe; The edge of described fastening base is provided with ring-shaped groove, band can be placed wherein, and fastening base is tightened.
Further, described the first through-hole diameter is 15.88 ~ 92mm, adapts with pipe-line system copper pipe; Described the second through-hole diameter is 6 ~ 16mm, adapts with needle-valve.
Further, the extended distance of described the first breach and the second breach is 0.5 ~ 16mm.
Further, the geometry of described fastening base is that lower end is circular arc, and upper end is plane, and centre is connected by tangent line.
Further, described fastening base is made up of elastomeric material.
The beneficial effects of the utility model:
The utility model is reasonable in design, simple in structure, easy to use, by two through holes on fastening base, needle-valve and pipeline copper pipe are fixed, and tightened with band, can effectively avoid breaking because air conditioning pipe system copper pipe vibrates the needle-valve solder joint causing, by the running quality of air-conditioning.
Brief description of the drawings
Fig. 1 is the schematic diagram of needle-valve and the welding of pipe-line system copper pipe.
Fig. 2 is front view of the present utility model, right view and top view.
Fig. 3 is the schematic diagram of the actual use of the utility model.
Wherein: 1-fastening base; 2-the first through hole; 3-the second through hole; 4-the first breach; 5-the second breach; 6-slot to make way; 7-ring-shaped groove; 8-needle-valve; 9-pipe-line system copper pipe; 10-band.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figures 2 and 3, the utility model comprises fastening base 1.The bottom of described fastening base 1 is provided with the first through hole 2, and top is provided with the second through hole 3 vertical with the first through hole 2 and that communicate.The side of described the first through hole and the second through hole has the first breach 4 and second breach 5 of perforation, makes fastening base 1 can be arranged on the junction of needle-valve 8 and pipe-line system copper pipe 9; The edge of described fastening base 1 is provided with ring-shaped groove 7, band 10 can be tightened in this ring-shaped groove 7, and fastening base 1 is fastened on pipe-line system copper pipe 9.Further, the diameter of described the first through hole 2 is 15.88 ~ 92mm, and itself and pipe-line system copper pipe 9 are adapted.The diameter of described the second through hole 3 is 6 ~ 16mm, and itself and needle-valve are adapted.Further, the extended distance of described the first breach 4 and the second breach 5 is 0.5 ~ 16mm, is convenient to the first through hole 2 to be arranged on pipe-line system copper pipe 9, and the second through hole 3 is installed on needle-valve 8.Further, the geometry of described fastening base 1 is that lower end is circular arc, and upper end is plane, and centre is connected by tangent line, similar to pipeline shape, can make itself and pipeline combination better.Further, described fastening base is made up of elastomeric material.The composition of elastomeric material is acrylonitrile-butadiene rubber, has advantages of that wearability is high, good heat resistance, ageing-resistant, is applicable to for fixing for a long time needle-valve 8.
When use, the first through hole 2 of fastening base 1 is sleeved on pipe-line system copper pipe 9, and mobile fastening base 1, make the second breach 5 snap in needle-valve 8, until the second through hole 3 combines with needle-valve 8.Because needle-valve 8 is to be welded on the flanging bore of pipe-line system copper pipe 9, be therefore provided with slot to make way 6 at the first through hole 2 and the second through hole 3 joints, the second through hole 3 can better be fitted with needle-valve 8.Finally, tighten at ring-shaped groove 7 places of fastening base 1 with band 10, needle-valve 8 and pipe-line system copper pipe 9 are fixed together firmly.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
