Abstract
The utility model relates to an automatic water valve. A valve body is a three-way pipe; a film sheet is pressed and clamped between the valve body and an upper press cover through a through hole and the upper press cover. A spring is arranged between the film sheet and a pressure regulation screw nut, and a sealing cap cover is arranged on the pressure regulation screw nut. The valve body is divided into a sealing water inlet chamber and a sealing water outlet chamber by a transmission rod which is sheathed in a horn-shaped inner support piece; the lower end of the transmission rod is connected with a sealing pad which is sheathed in a horn neck of the inner support piece, and the other end of the transmission rod is connected with the film sheet and the support sheet through the transmission rod screw nut. A chamber which is connected with the film sheet is the water outlet chamber, and a water flow decelerating film sheet is arranged in the water inlet chamber of the water valve. The automatic water valve overcomes the defect of easy damage of the film sheet of the existing water valve.
Description
(1) technical field
The utility model relates to a kind of Automatic water valve, especially is applicable to the altitude valve on the solar water heater.
(2) background technique
The altitude valve kind is a lot of in the market, Patent Office of the People's Republic of China's disclosed " the two-way switching automatic loading water of diaphragm type valve " (number of patent application 98240194.9) is a kind of water level control device that three-way pipe is installed, and this device drives valve rod by hydraulic pressure and realizes.The main shortcoming of this device is, when water flow velocity is big, is easy to break through diaphragm, causes this device can not carry out water level and controls automatically; In addition, because water inlet does not have filtrating equipment, feedwater quality to can not get ensureing, easy knot dirt in water valve and the water heater, shorten working life.
(3) summary of the invention
The utility model has solved the easy impaired shortcoming of water valve diaphragm in the prior art, and a kind of work safety, stable is provided, and is difficult for impaired Automatic water valve.
For this reason, the utility model is by the following technical solutions:
A kind of Automatic water valve, valve body is a three-way pipe, one port and upper press cover 3 are pressed diaphragm 7 and are sandwiched between valve body and the upper press cover, shock mount 4 between diaphragm and the pressure adjusting nut 2, be stamped sealed cap 1 on the pressure adjusting nut, the dowel bar 8 in the supporting element 3 is separated into closed water-inlet cavity 15 and water chamber 14 with described valve body to described valve body in the flue by being socketed in, the dowel bar lower end connects a sealing gasket 9, in the horn throat of supporting element, the other end linked to each other with described diaphragm 7 and support plate 6 by dowel bar nut 5 in described sealing gasket was socketed on.
Described water-inlet cavity is set at water chamber: the chamber that links to each other with described diaphragm is a water chamber.
In the further described water valve water-inlet cavity current deceleration diaphragm is housed.
Further more described Automatic water valve, described current deceleration diaphragm is fitted with auxiliary diaphragm 11 by catch 10 and is formed, described catch is except that central ring leaves porous 16, central ring still has some apertures 17 outward, described auxiliary diaphragm central ring has " ten " word gap 18, has the aperture of identical size outside the central ring with the catch relevant position.
Further more described catch central ring has two apertures outward.
Described Automatic water valve, there is a filter screen 12 at described valve inleting water mouth place.
The utility model has the following advantages with respect to existing Automatic water valve:
1, water chamber is located at a side identical with diaphragm, can make diaphragm avoid the impact of water-inlet cavity big flow of moment, and diaphragm is not fragile.
2, the water-inlet cavity current of packing into slow down and can prevent that flow of inlet water moment is excessive behind the diaphragm and make dowel bar seal water intake, and it is not impaired to make in the water valve current be tending towards relaxing the protection diaphragm yet.
(4) description of drawings
Fig. 1 is that the utility model master looks sectional view
Fig. 2 is that the utility model current slow down diaphragm catch schematic representation
Fig. 2 is that the utility model current slow down diaphragm auxiliary diaphragm schematic representation
(5) specific implementation method
Below in conjunction with accompanying drawing the utility model is described further:
A kind of Automatic water valve that is used for solar water heater, valve body are a three-way pipe, and a port and upper press cover 3 are pressed diaphragm 7 and be sandwiched between valve body and the upper press cover, and shock mount 4 between diaphragm and the pressure adjusting nut 2 is stamped sealed cap 1 on the pressure adjusting nut; The dowel bar 8 in the supporting element 3 is separated into closed water-inlet cavity 15 and water chamber 14 with described valve body to valve body in the flue by being socketed in, the dowel bar lower end connects a sealing gasket 9, in the horn throat of supporting element, the other end linked to each other with described diaphragm 7 and support plate 6 by dowel bar nut 5 in described sealing gasket was socketed on; The chamber that links to each other with diaphragm is a water chamber, can make diaphragm avoid the impact of water-inlet cavity big flow of moment like this, and diaphragm is not fragile; The current speed reducer is housed in the water valve water-inlet cavity, the current speed reducer is fitted with auxiliary diaphragm 11 by catch 10 and is formed, catch is except that central ring leaves porous, central ring still has two apertures outward, the auxiliary diaphragm central ring has " ten " word gap, has the aperture of identical size outside the central ring with the catch relevant position.There is a filter screen 12 the Automatic water valve water inlet.The elastic force of pressure adjusting nut adjustable springs, thereby the water level of adjusting water heater inner storing water jar, the water level when spring is compacted in the water heater is higher.During Automatic water valve work, current see through filter membrane and enter water-inlet cavity, passed the water-leaking hole that current slow down effect auxiliary diaphragm and catch again, from dowel bar and tubaeform in slit between supporting element enter water chamber, enter the water heater water storage tank again, the water level of water storage tank is gradually full, hydraulic pressure is gradually big in the water chamber, the diaphragm pressurized upwards promotes gradually, drive on the dowel bar simultaneously and carry, flow from water-inlet cavity to water chamber is gradually little, treat that water level rises to certain altitude, the diaphragm pressurized drives the flow inlet that dowel bar is thoroughly sealed water-inlet cavity and water chamber, and water valve is in closed condition.When the aqua storage tank drawdown of water heater, hydraulic pressure is lower than the hydraulic pressure in the water-inlet cavity in the water chamber, makes dowel bar descend, dowel bar and interior supporting element seal to be opened, current enter water chamber from water-inlet cavity, enter the aqua storage tank of water heater again, and the autocontrol valve gate switch so circulates.
