Abstract
A floating ball control valve of a solar water heater comprises a floating ball, a link rod, a valve body and a valve clack, wherein the structure and the function of the floating ball are the same as those of a floating ball valve in the prior art. The valve body is a hollow piece, the central position of the upper end of the valve body is provided with a water inlet and a water outlet, a diaphragm is arranged in the valve body, a connecting rod is arranged on the diaphragm, and the diaphragm connecting rod penetrates through the water inlet and the water outlet at the upper end of the valve body and is connected with the connecting rod of the floating ball. The lower end of the valve body is also provided with a water inlet and a water outlet, and the number of the water inlets and the water outlets at the lower end of the valve body can be one or more, and is preferably 4 to 8. The valve is subject to the pulling force of the floating ball and the link rod and the upward thrust of the tap water, and the water inlet and the water outlet at the upper end of the valve body are closed when the water level in the water tank gradually rises.
Description
The utility model relates to by water valve, relates in particular to the floater controlled valve of solar water heater water supply usefulness.
Existing floater controlled valve generally is made up of ball float, water outlet, link rod and needle, and when ball float rose, link rod promoted needle with the leverage form and gradually water outlet clogged, and realizes damming.This relatively simple for structure, but, make water outlet and needle aging impaired easily because the pressure of Nei Saili and water is all bigger, cause work unreliable.
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of hydraulic pressure direction of complying with by current, solar water heater floater controlled valve simple in structure, safe and reliable.
Solar water heater floater controlled valve described in the utility model is made up of valve body, ball float, link rod and film lobe, and the ball float of described ball float and existing float valve is basic identical.Valve body is interior empty part, is provided with intake-outlet in the central position, upper end of valve body, also is provided with intake-outlet in the lower end of valve body.The intake-outlet of valve body upper end has only one, and film lobe link rod passes from the intake-outlet of upper end, and the last termination ball float link rod of film lobe link rod is so float valve is promptly sealed or opens in the lifting with the lifting of ball float of film lobe.The intake-outlet of valve body lower end can be provided with one in the central position, but intake-outlet especially when water inlet impulse force bigger, water valve is suffered damage, had better adopt the porous form of annular, promptly a plurality of intake-outlets are set, generally are advisable with 4 to 8 intake-outlets in valve body lower end.Certainly, the size specification difference of stop valve, the quantity of the intake-outlet that valve body lower end is provided with also can be different.The film lobe is set in the valve body, is connected with film lobe link rod on the film lobe, film lobe link rod passes the intake-outlet of valve body upper end, links with the ball float link rod.Ball float rises under the water surface buoyancy function in water tank or descends, and promptly can and close and open the intake-outlet of valve body upper end in synchronous rising in descending.
Use solar water heater floater controlled valve technology described in the utility model, existing float valve water pressure and confronting with each other have been avoided by plug pressure, when float valve of the present utility model ends, the power that draws high that is subjected to ball float simultaneously and is produced and the pressure of tap water upper punch, make the film lobe close closelyr, so solar water heater floater controlled valve described in the utility model work is more reliable.
Accompanying drawing is the structural representation of solar water heater floater controlled valve described in the utility model.
1-ball float, 2-link rod, 3-link rod, 4-valve body, 5-film lobe
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: ball float (1) is identical with the ball float structure of the float valve of prior art, acts on also identical.The front end of link rod (2) and ball float (1) are fixedly connected, and the rear end of link rod (2) is arranged on the fulcrum on the valve body (4).The upper end that is provided with interface and link rod (3) at link rod (2) links.Film lobe (5) in the lower end of link rod (3) and the valve body is fixedly connected.Supplying water from the intake-outlet of valve body upper end makes that the water surface constantly raises in the water tank, and ball float (1) will constantly raise, and ball float (1) will pass through membrane lobe (5) on link rod (2) and the link rod (3), gradually the intake-outlet on the valve body is closed.When water level was reduced to certain position in the water tank, under the effect of ball float self pressure, film lobe (5) can be opened again, realized supplying water in the trend water tank.
Claims (2)
1, a kind of solar water heater floater controlled valve, there are ball float (1), link rod (2), link rod (3), valve body (4) and film lobe (5) to form, it is characterized in that valve body (4) is interior empty part, the upper end of valve body (4) is provided with intake-outlet, and the lower end of valve body (4) also is provided with intake-outlet.
2, solar water heater floater controlled valve according to claim 1 is characterized in that being provided with film lobe (5) in valve body (4), and link rod (3) is installed on the film lobe (5), and intake-outlet and link rod (2) that link rod (3) passes valve body (4) upper end link.
