Abstract
The utility model relates to an anti-frost-crack release valve utilized in pips, a valve body is provided in a valve shell, an inlet, a spool, a spring, an adjusting bolt and an outlet are arranged in the inner cavity of the valve body, and the end-portion of the outlet is arranged in the center of gyration of the pipe. The outlet goes downward and is vertical to the level, and the spool can be cone sealed, plane sealed and ball sealed. Installing the anti-frost-crack release valve of the utility model when connecting the pipes, when the pressure in the pipe increase in the process of liquid in the pipe freezing gradually in cold-seasons, the spool will press the spring to open and release part of the liquid, reduces the pressure in the pipeline, thereby guaranteeing the pipeline not being broken by over-high pressure.
Description
Technical field:
The utility model relates to a kind of Safety valve that splits at the weather water pipe anti-freezing of cold.
Background technique:
Under the weather conditions of cold, run into running water pipe or other pipelines by the situation of bursting by freezing through regular meeting.The process that liquid in the pipeline is frozen into ice is frozen into ice from the liquid of the most close tube wall to freeze center to pipeline more gradually at first, the volume that liquid build-ups ice in this process is increasing, and the water that is still liquid just has been subjected to extruding and has produced pressure, if ducted pressure increases to and is enough to burst tube wall and just forms breaking of pipeline.
The model utility content:
The purpose of this utility model is to overcome the problem that dead season, conduit pipeline broke, the Safety valve that provides a kind of water pipe anti-freezing to split.
The utility model water pipe anti-freezing splits the technological scheme of safety valve, comprise the valve casing that is connected with water pipe, described valve shell cavity is provided with valve body, the front portion of the inner chamber of valve body is provided with water intake and spool, the rear portion of spool is provided with spring, the rear portion of spring has regulates the rear portion that bolt is installed on body cavity, regulates bolt and is provided with water outlet, and the end of described water intake is near the gyration center of described water pipe.The end of described water intake is at the gyration center of water pipe.Described water outlet is downward perpendicular to level.Described spool can be the cone sealing, also can be plane sealing, can also be ball seal.
The beneficial effects of the utility model are: only need to load onto water pipe anti-freezing of the present utility model when pipeline connects and split safety valve, liquid in dead season pipeline pressure in the pipeline in the process that is frozen into ice gradually increases, spool pressuring spring and opening, discharge section liquid, reduce ducted pressure, thereby guaranteed that pipeline is not bursting at the collision.
Description of drawings:
Fig. 1 is that the utility model water pipe anti-freezing splits the safety valve plan view;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to view.
Embodiment:
Fig. 1, Fig. 2, the utility model water pipe anti-freezing shown in Figure 3 split safety valve, comprise the valve casing 1 that is connected with water pipe 6, its valve casing 1 inner chamber is provided with valve body 2, the front portion of the inner chamber of valve body 2 is provided with water intake 7 and spool 3, the rear portion of spool 3 is provided with spring 4, the rear portion of spring 4 has regulates the rear portion that bolt 5 is installed on valve body 2 inner chambers, regulates bolt 5 and is provided with water outlet 8, and the end of its water intake 7 is at the gyration center of water pipe 6.Its water outlet 8 is downward perpendicular to level.Its spool 3 is cone sealings.
The three-way union that the utility model water pipe anti-freezing splits the valve casing 1 usefulness water pipe commonly used of safety valve just can substitute.
