Abstract
The utility model relates to a water level automatic control valve, which is a water level control device used for a solar water heater and comprises a valve core chamber 9, a valve core 7, a valve rod 6, a diaphragm chamber 3, a diaphragm 4 and a pressing control valve 22. An outlet of the valve core chamber 9 is closed based on the pressure of the over-flown water after the solar water heater is fully filled to the diaphragm, and consequently the utility model achieves the functions of automatically closing a water inlet and automatically opening the valve when discharging the hot water. The utility model is arranged on the solar water heater, can cause the operation of the solar water heater to become convenient, saves time and realizes the automatic control without electricity.
Description
The utility model relates to the water-level control apparatus that a kind of solar water heater is used, a kind of water level autocontrol valve.
When solar water heater uses, observe overflow pipe, can confirm in the water tank fills with water when water to be had overflows when when water storage box adds water, seeing, should close inlet valve this moment, waits for that then the sun with after the water heating, opens outlet valve again and use hot water, then open inlet valve again, replenish cold water.The operation more complicated.
The purpose of this utility model is to propose a kind ofly to be filled to Man Shineng at solar water heater water tank and to close water intake automatically, and can open the water level autocontrol valve of valve when putting hot water automatically.
This water level autocontrol valve comprises valve core chamber, spool, valve rod, diaphragm chamber, diaphragm and a voltage-controlled valve.Spool is in the valve core chamber, and spool links to each other with the center of diaphragm by valve rod; Diaphragm is divided into backwater room and air chamber two-part with diaphragm chamber, and air chamber is connected with the external world, and there are a water intake and a water outlet in diaphragm chamber; There are an import and an outlet in valve core chamber, and the interior edge face of valve core chamber outlet is a sealing surface, and is relative with diaphragm seal on the spool; Water inlet, osculum and pressure control hole are arranged on the voltage-controlled valve, there is one voltage-controlled in the voltage-controlled valve, voltage-controlled inner chamber with voltage-controlled valve is separated into two-part, above-mentioned water inlet and osculum are all the same side of voltage-controlled, the pressure control hole is at voltage-controlled opposite side, and the interior edge face of water inlet is relative with voltage-controlled sealing surface; The water intake of described diaphragm chamber and water outlet all are on the wall of backwater room; The water inlet of described voltage-controlled valve links to each other with the water outlet of diaphragm chamber.
Accompanying drawing 1 is the structural drawing of this water level autocontrol valve;
Accompanying drawing 2 is the schematic diagram with this water level autocontrol valve control solar water heater.
As shown in Figure 1, this water level autocontrol valve comprises valve core chamber 9, spool 7, valve rod 6, diaphragm chamber 3, diaphragm 4 and voltage-controlled valve 22.Spool is in the valve core chamber, and spool links to each other with the center of diaphragm by valve rod, and when diaphragm moved right, valve rod promptly promoted spool and moves to right, and makes the interior edge face 10 of diaphragm seal 8 and the valve core chamber outlet 11 on the spool contact and seal, and exports promptly to be closed.The import 12 of valve core chamber 9 is on valve core chamber's sidewall, is used for linking to each other with intake pipe.Diaphragm 4 is separated into backwater room 2 and air chamber 5 two-part with diaphragm chamber, air chamber is connected with the external world, 15 are the hole that air chamber is in communication with the outside, one water intake 1 and a water outlet 16 are arranged on the backwater locular wall of diaphragm chamber, water intake is used for linking to each other with the overflow pipe of solar water heater, and water outlet links to each other with the water inlet 17 of voltage-controlled valve 22.Voltage-controlled 20 inner chamber with voltage-controlled valve in the voltage-controlled valve is separated into two-part, the water inlet 17 of voltage-controlled valve and osculum 18 are all the same side of voltage-controlled, the pressure control hole 21 of voltage-controlled valve is at voltage-controlled opposite side, the interior edge face 19 of water inlet 17 is relative with voltage-controlled 20 sealing surface, when charging into the tap water of certain pressure in the pressure control hole 21, shift to the water inlet for voltage-controlled, and the water inlet pushed down, it is closed, hydraulic pressure disappearance when pressure control hole one side, the hydraulic pressure of voltage-controlled self-dependent elasticity and water inlet one side and resilience, water inlet and osculum form path.
As shown in Figure 2, when this water level autocontrol valve uses, water intake in the diaphragm chamber 31 is linked to each other with the overflow pipe 25 of solar water heater 23, and the outlet 11 of valve core chamber links to each other with the water intake 26 of solar water heater, and the import 12 of valve core chamber and the pressure control hole 21 of voltage-controlled valve link to each other with intake pipe 27.Intake pipe then is connected with running water pipe by a Cold water tap 29 on the one hand, also links to each other with the valve 28 that puts hot water on the other hand.During installing, require the overflow 24 low enough height of automatic controller for water level than solar water heater, for example, more than 1.5 meters.As depicted in figs. 1 and 2, during to solar water heater watering, the valve 28 that puts hot water is closed, open Cold water tap 29, tap water just enters the water intake 26 of solar water heater by the valve core chamber 9 of automatic controller for water level, tap water also enters the pressure control hole 21 of voltage-controlled valve 22 on the other hand, presses to water inlet 17 with voltage-controlled 20, and water inlet 17 is closed.When being full of cold water in the solar water heater, Yu Shui will flow out from overflow 24, enter in the backwater room 2 of water level autocontrol valve, when backwater room 2 and return pipe 25 inner products behind the water of certain altitude, diaphragm 4 is subjected to hydraulic pressure and moves, and by the transmission of valve rod 6, spool 7, diaphragm seal 8 is pressed to the outlet 11 of valve core chamber, with port closing, solar water heater is no longer water inlet just.When putting hot water, close Cold water tap 29, open the valve 28 that puts hot water, water in the intake pipe 27 flows out from the heat release water valve, the hydraulic pressure of pressure control hole 21 1 sides disappears in the voltage-controlled valve 22, get back to original position for voltage-controlled 20, water inlet 17 is opened, ponding in backwater room 2 and the return pipe 25 flows out outside the valve by the water inlet 17 and the osculum 18 of voltage-controlled valve, the pressure that is subjected on the diaphragm 4 disappears, diaphragm 4, valve rod 6 and spool 7, diaphragm seal 8 retreat, and the outlet of valve core chamber is opened, and the hot water in the solar water heater just flows out by the valve core chamber and the valve that puts hot water.
From as can be known above-mentioned, installed this automatic controller for water level after, after solar water heater water tank is full of water, can close water intake automatically, cut off cold water source.As long as close Cold water tap during with hot water, open the valve that puts hot water and to supply with hot water.Realized not having electricity control automatically.
As shown in Figure 1, this water level autocontrol valve can also comprise a water inlet 13, and the upper end of water inlet links to each other with the import of valve core chamber 12, has one to be used for the connection mouth 14 that links to each other with the pressure control hole 21 of voltage-controlled valve on the wall of water inlet.Water inlet and valve core chamber can fuse.
