Abstract
The utility model provides a time delay self-closing valve, which is characterized in that the valve body is provided with a reset spring inside, a tightening seal ring, the top of the valve body is provided with a nameplate. The device has advantage of simple structure, easy operation, which can select delaying time and water flow amount, particularly suitable for using on washing equipment in the toilet.
Description
Technical field:
The utility model belongs to a kind of hot-water heating device, relates to a kind of waterpipe valve.
Background technique:
The waterpipe valve has varied, as screw thread screw type, compressing rise-fall type and rotary ball valve formula etc.Valve with time-delay closing function also has, but the delay time that has can not select, and the flow that has can not be regulated, the use inconvenience that has.
Summary of the invention:
The purpose of this utility model provides had a kind ofly both had the delay-self-closing function, and delay time and flow can be selected again, self-closing valve easy to use.
The technical solution of the utility model is: set up Returnning spring and fit sealing circle on screw thread screw type valve basis in valve body, nameplate is established in the valve body upper end.
The beneficial effects of the utility model are: Returnning spring can drive valve rod and rotate the time-delay closing valve that automatically resets; Delay time and flow can freely be selected by the handle rotation angle.
Description of drawings:
Accompanying drawing 1 is a delay-self-closing valve mechanism principle schematic.
1 is the water channel of coming in and going out, and 2 is valve body, and 3 is handle, and 4 is nameplate, and 5 is Returnning spring, and 6 is valve rod, and 7 is the fit sealing circle, and 8 for opening and closing valve plug, and 9 is the valve plug rubber pad.
Embodiment:
Embodiment illustrates that the utility model structural principle is as follows in conjunction with the accompanying drawings.
The delay-self-closing valve is made up of come in and go out water channel 1 and control valve body 2; Be provided with Returnning spring 5 in the valve body 2, Returnning spring 5 one ends link to each other with valve body wall, and the other end links to each other with valve rod 6; Fit sealing circle 7 is established in valve body internal thread and valve rod 6 contacting points, to improve sealing, increases frictional force, makes reseting procedure stable level and smooth; Valve body 2 upper ends are provided with nameplate 4, and nameplate 4 is provided with signs such as " large and small, passes ", in order to select the valve working state and to limit the handle angle of swing.
The utility model working procedure is as follows:
By nameplate 4 signs valve handle 3 is screwed to " greatly " or " little " position, valve rod 6 will open and close valve plug 8 with the handle rotation and be raised to the relevant position, and the water channel 1 of coming in and going out is got through the beginning water flowing.Returnning spring 5 is because stressed simultaneously, and beginning oppositely discharges and resets, and drives valve plug 8 by valve rod 6 and moves down.Through the certain time-delay time, valve plug 8 is blocked the water channel 1 of coming in and going out, and valve is closed automatically.
Claims (1)
1, a kind of delay-self-closing valve, form by come in and go out water channel and control valve body, screw thread, handle, valve rod, valve plug etc. are arranged on the valve body, it is characterized in that: be provided with Returnning spring in the valve body, valve body internal thread and valve rod contacting point are provided with the fit sealing circle, and valve body top is provided with nameplate.
