Abstract

This invention relates to a connection valve of a separated air conditioner, which include two connecting pipes and one connecting pipe nut. One of the two connecting pipes with a hollow conical surface and the other one with a spherical convex surface at their opposite ends respectively. A linear contact is formed between the two surfaces by the connecting pipe nut, the characterized by the outer diameter of the spherical convex surface is larger than the inner diameter of the outer connecting pipe, and equal or smaller than the outer diameter of the outer connecting pipe. As a result, the connecting pipe nut locked the spherical convex surface directly to connect the two connecting pipes therebetween. Thus improve the efficiency and reliability of the product.

Description

分体空调机的连接阀 本发明所属技术领域  Connection valve of split air conditioner TECHNICAL FIELD
本发明提供一种连接阔， 特别是一种分体空调机的连接阀。  The invention provides a connection valve, particularly a connection valve of a split air conditioner.
在本发明之前的现有技术 Prior art prior to the present invention
现有技术的分体空调机室内、 外机管的连接阔如附图 1 所示， 图 1 中： 包括外 接管 1 , 接管螺母 2， 内接管 3铜管 4， 内接管 3上螺母固定凸台 5， 接管螺母 2扣紧 凸台 5， 而固定内、 外接管， 现时的凸台 5有两种制造方法：  The connection between the indoor and outdoor pipes of the split air conditioner in the prior art is as shown in FIG. 1. In FIG. 1: including the external pipe 1, the connecting nut 2, the internal connecting pipe 3, the copper pipe 4, and the internal fixing pipe 3 with a nut fixing projection. There are two manufacturing methods for the stand 5 and the takeover nut 2 to fasten the stand 5 to fix the inner and outer pipes.
①、 是悍接在内接管 3上， 生产工序复杂， 且易产生松脱的现象， 特别是重复安 装使用时。  ①, it is connected to the inner pipe 3, the production process is complicated, and the phenomenon of loosening is easy to occur, especially when it is repeatedly installed and used.
②、 是与内接管 3—体造出， 这样在加工时就需多一道工序， 且收紧螺母 2时， 力量不好控制， 力量大了也会将凸台 5拉断。  ② It is made with the inner pipe 3-body, so one more process is required during processing, and when the nut 2 is tightened, the power is not controlled, and the boss 5 will be broken if the power is too strong.
发明目的  Object of the invention
本发明的目的在于提供一种不易损坏， 且能可靠多次装拆的分体空调机的连接 阀。  An object of the present invention is to provide a connection valve of a split air conditioner which is not easily damaged and can be reliably assembled and disassembled multiple times.
本发明的技术方案  Technical solution of the present invention
本发明的技术方案是这样的： 分体空调机的连接阀， 它有外接管、 内接管， 内、 外接管一边是凸球面， 另一边是内锥面， 外接管外缘有螺纹， 一接管螺母连接内、 外 接管使内接管的凸球面与外接管的内锥面线接触配合连接， 其特征在于， 内接管的凸 球面球体最大外径大于外接管的内锥面内径并小于等于外接管的外径。  The technical solution of the present invention is as follows: The connection valve of a split air conditioner has an external pipe and an internal pipe. One side of the internal and external pipe is a convex spherical surface and the other side is an inner cone surface. The outer edge of the external pipe is threaded. The nut is connected to the inner and outer pipes so that the convex spherical surface of the inner pipe and the inner tapered surface of the outer pipe are in line-contact connection, and is characterized in that the maximum outer diameter of the convex spherical sphere of the inner pipe is larger than the inner diameter of the outer pipe and smaller than or equal to the outer pipe Of outer diameter.
附图说明  BRIEF DESCRIPTION OF THE DRAWINGS
下面通过附图和实施例进一步说明本发明的具体内容， 以及所能达成的功效， 其中：  The specific content of the present invention and the effects that can be achieved are further described below with reference to the drawings and embodiments, where:
图 1是现有技术连接阀的结构图；  FIG. 1 is a structural diagram of a prior art connection valve;
图 2是本发明球面阀的结构图。  Fig. 2 is a structural diagram of a spherical valve according to the present invention.
本发明的实施例  Examples of the invention
如图 2所示， 其中包括： 外接管 1， 接管螺母 2， 内接管 3， 铜管 4， 内接管 3 上凸球体 6。 外接管 1接口内设计成一内锥面 11， 外接管外缘有螺纹， 内接管 3接口 处顶端设计成凸球面形成一凸球体 6， 凸球体 6最大外径大于外接管 1的内径， 小于 等于外接管 1的外径。 使用时， 内接管 3的凸球面伸入外接管 1的内锥面内， 接管螺 母 2扣着内接管 3上的凸球体 6, 与外接管 1上螺纹啮合， 在凸球面与外接管 1的内 锥面和接管螺母 2的轴向压力下自动对准中心， 线接触配合密封。 As shown in FIG. 2, it includes: an external pipe 1, a connecting nut 2, an internal pipe 3, a copper pipe 4, and an internal pipe 3 with a convex sphere 6. The outer tube 1 interface is designed with an inner cone surface 11 and the outer edge of the outer tube is threaded. The top end of the inner tube 3 interface is designed with a convex spherical surface to form a convex sphere 6. The maximum outer diameter of the convex sphere 6 is greater than the internal diameter of the external tube 1 The outer diameter of the external tube 1. In use, the convex spherical surface of the inner pipe 3 projects into the inner cone surface of the outer pipe 1, and the pipe screw The female 2 buckles the convex sphere 6 on the inner pipe 3, and engages the thread on the outer pipe 1, and automatically aligns the center under the axial pressure of the convex spherical surface and the inner cone surface of the outer pipe 1 and the pipe nut 2. The line contact fits and seals .
