Abstract

The invention provides a structure for connecting a valve body with a connector in a steam heat valve, and belongs to the technical field of valves, wherein the structure solves the problem that insertion bending easily occurs when a movable connector and a valve body of an existing steam heat valve are connected. According to the structure, a cavity is formed inside the valve body, the valve body is provided with a connecting end communicated with the cavity, the structure comprises a connector inner end, a locking nut and an annular groove formed in the end face of the connecting end, the connector inner end is cylindrical, the connector inner end is inserted into the annular groove, the inner side of the locking nut is provided with a protruding blocking edge, the locking nut is connected with the connecting end in a threaded mode, the outer side of a connector outer end is provided with an annular protruding shoulder, and the blocking edge abuts against the annular protruding shoulder so that the connector inner end can be fixed in the annular groove in a sealed mode. The structure for connecting the valve body with the connector in the steam heat valve has the advantage that the connector can be stably inserted into the valve body.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a heating valve, in particular to a connection structure between a valve body and a joint in the heating valve. Background technique [0002] The automatic temperature control heating valve on the heating pipe is usually set in front of the inlet of the heating radiator. One end is connected to the heating radiator and the other end is connected to the heating pipe. There is a temperature bulb for automatic temperature control in the valve body. The temperature bulb expands and contracts according to the ambient temperature. The lower end of the telescopic part is connected with the valve stem of the valve through a transmission part or a transmission assembly. The automatic constant heating and heating valve uses the temperature sensing element in the temperature control valve head to control the valve lift. [0003] Its working principle is that when the room temperature rises, t...
