Abstract

The invention provides a loose joint device for a valve and a pipe fitting, and relates to the technical field of loose joint structures. The loose joint device for the valve and the pipe fitting comprises a loose joint part and a valve body connector, wherein the loose joint part comprises a pipe body; any end of the pipe body is detachably connected with the valve body connector; the other end of the pipe body is provided with a connecting port; a connecting pipe matched with the connecting port is arranged in the connecting port in a penetrating manner; a sealing part is arranged on the side wall, opposite to the connecting port, of the connecting pipe; and a locking piece for locking the connecting pipe on the pipe body is arranged on the pipe body. According to the loose joint device for the valve and the pipe fitting provided by the invention, the pipe body can be connected with any one of the pipeline or the valve body connector firstly, then the connecting pipe penetrating through the connecting port is connected with the valve body connector or the pipeline, the connecting pipe and the valve body connector can rotate relatively at the moment, and after the pipeline and the valve body connector are connected with the loose joint part respectively, the connecting pipe is fixed onto the pipe body through the locking piece arranged on the pipe body, so that the connecting pipe and the pipe body are prevented from rotating.

Description

technical field [0001] The invention relates to the technical field of joint structures, in particular to a joint device for valves and pipe fittings. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest globe valve to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. Valves are used to open and close pipelines, control flow direction, regulate and control delivery. The pipeline accessories of the parameters of the medium (temperature, pressure and flow), and the connection between the valve and the pipe fittings need to use the union structure, but there are still some problems in the existing union structure: [0003] For example, when the existing join...
