Embodiment Construction

[0016] As shown in Figure 1 and Figure 2, the flow safety valve includes a valve body 1, a connecting head 2, a diverter cone 3, a valve core 4, a sealing sleeve 5, a spring 6 and a connecting nut 7 and other parts.

[0017] As shown in FIGS. 2 and 3 , the valve body 1 is cylindrical, and there is a water inlet hole 1 a in the valve body 1 . There is a connecting nut 7 at the rear end of the valve body 1, and the valve body 1 is connected with the water delivery pipeline through the connecting nut 7. In this embodiment, a snap ring 9 is provided between the connecting nut 7 and the valve body 1, so that the connecting nut 7 can rotate relative to the valve body 1 but will not be separated from the valve body 1, so as to facilitate the connection between the nut 7 and the water delivery Pipe socket. At the same time, a sealing washer 8 is provided between the connecting nut 7 and the valve body 1 to play a sealing role.

[0018] As shown in FIG. 2 and FIG. 3 , the connecting ...

Abstract

The invention is the flow safe valve and belongs to the mechanic technology. The invention comprises the valve body and the connecting head. The valve body is the columnar shape and has the water inlet aperture; the connecting head links to the valve body through the screw thread and has the water outlet aperture. The valve builds in a packing gland that is columnar shape and has a shunt prick a the end, and the shunt prick is equipped in the water inlet aperture and has the water channels; the packing gland has the valve core and the spring; the two ends of the spring separately function on the valve core and the shunt prick; the valve core has a gag to block up the shunt prick when the valve core and the prick contact. The invention can avoids the waste of the water resources and has simple utilization.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a safety device installed in a water appliance and a water source pipeline system for matching connection. Background technique [0002] Water appliances are generally directly connected to water pipelines through connecting pipes. The water in the water pipeline enters the water appliance through the connecting pipe. Under normal circumstances, when the water appliance is turned on, the water flow will flow to the water appliance continuously through the connecting pipe from the water delivery pipeline. [0003] However, when abnormal conditions occur in the water pipe, such as the connecting pipe falling off or breaking, and the water appliance being damaged, etc., a large amount of water leakage will be caused. [0004] Although, in the field of chemical industry or petroleum, there are some devices that can automatically close and play a safety role, such as t...
