Abstract
The utility model provides a unidirectional water-jet switch for a solar water heater, which belongs to the application field of the solar water heater, in case of the backflow of the hot water in the solar water heater during water injection due to the insufficient water pressure. The unidirectional water-jet switch for the solar water heater comprises a tube wall (1), which is characterized in that the upper part of the tube wall (1) is provided with a unidirectional waterflow control device which is connected with a spherical valve switch. The unidirectional waterflow control device comprises a wedge piston (3), a piston baffle (2) and the tube wall (1); the piston baffle (2) is connected with the tube wall (1); the wedge piston (3) is movable in the space between the piston baffle (2) and the tube wall (1). The utility model has the beneficial effect of simple structure, low cost and reliable security.
Description
Technical field
The utility model belongs to the daily life tools field, particularly a kind of solar water heater one way entrapped water switch, the problem of solution flow backwards in the solar water heater the injecting process.
Background technology
Utilizing running water in the process of solar water heater water filling, crossing low even during the situation of cutting off the water, often under the situation that people are difficult for discovering, the water in the solar water heater forms and pours in down a chimney, and has lost a large amount of hot water on the contrary if run into hydraulic pressure.
Summary of the invention
The purpose of this utility model provides a kind of one way entrapped water switch of simple in structure, the flow backwards that can stop solar water heater.
Its technical scheme that the utility model solves is, a kind of solar water heater one way entrapped water switch, comprise tube wall, it is characterized in that: establish the unimodal current control device on the top of tube wall and link to each other with the globe valve switch, described unimodal current control device is made of wedge plungers, piston baffle and tube wall, piston baffle and tube wall join, and wedge plungers can be movable in the space of piston baffle and tube wall formation.
The beneficial effects of the utility model are simple in structure, with low cost, safe and reliable.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, tube wall, 2, piston baffle, 3, wedge plungers, 4, globe valve.
The specific embodiment
As shown in the figure, a kind of solar water heater one way entrapped water switch comprises tube wall 1, piston baffle 2, wedge plungers 3, globe valve 4.Globe valve is controlled the switch of normal current, and wedge plungers is installed in water and flows out a side, agrees with tube wall or separates, thereby control cut-offfing of current.Piston baffle is installed in the upper end of wedge plungers, guarantees that current normally pass through, and the control wedge plungers is movable within the specific limits.
When globe valve is opened to the solar water heater water filling, when hydraulic pressure just often, wedge plungers moves upward, the permeable hole normal water filling of current by piston baffle; When hydraulic pressure was crossed low or cut off the water, current in the tube wall and gravity acting in conjunction formed downward pressure to wedge plungers, and wedge plungers and tube wall agree with, and the blocking-up current avoid preventing the hot water emission in the solar energy.
Claims (1)
