Abstract
The utility model relates to a built-in automatic water charging valve for a solar water heater, which is characterized in that a valve cover (2) is connected to a suction pipe (3); a valve rod (4) is upwards connected to a floating ball (5) by passing through the valve cover and the lower end thereof is connected to a rubber sealing element (6); a jacket (7) is arranged inside a valve body (1); and the rubber sealing element (6) and a sliding sleeve (8) can move up and down in the jacket. When the water is charged, water is discharged from the suction pipe (3) through a water flow channel (17) in the valve body, so the sealing element can be efficiently protected against being impacted by the water flow. When reaching the water level, the rubber sealing element (6) seals the valve cover (2) so as to automatically stop the water. When hot water is required, due to the negative pressure, the hot water enters the water flow channel (17) through the suction pipe (3) and the valve cover (2) and then discharges from a water outlet (11) of the valve body. The utility model has the advantages of compact structure, reliability, convenient assembly and self-cleaning anti-blocking function.

Owing to adopted technique scheme, make when water arrives full water level on the utility model, can stop automatically going up water, have compact structure, profile is succinct, and is sensitive reliable, is convenient to install, and has the anticlogging characteristics of self-cleaning, has good practical values.
Below in conjunction with accompanying drawing the utility model is specifically described.
Description of drawings:
Fig. 1 is the utility model first embodiment's a structural representation;
Fig. 2 is the utility model second embodiment's a structural representation.
Embodiment
Embodiment one:
Referring to Fig. 1, the built-in automatic loading water valve of the solar water heater that the utility model provides, mainly form by valve body 1, valve gap 2, suction pipe 3, sheath 7, seal 6, sliding sleeve 8, valve rod 4 and ball float 5, valve body 1 lower end is provided with intake-outlet 11, the upper end is connected with valve gap 2, is provided with cavity 22 in the valve gap 2.Valve gap 2 spins with valve body 1 and seals by seal ring 9, valve gap 2 sides connect a suction pipe 3 and cavity 22 UNICOMs, suction pipe 3 is pressed close to valve body 1 and is extended downward valve body 1 intake-outlet 11 places, and with intake-outlet 11 at a distance of certain distance h, so that as far as possible the water of water tank bottom is discharged by suction pipe 3.The round end boss 41 of valve rod 4 bottoms connects with step hole 61 socket joints of rubbery sealed body 6, and connection back valve rod 4 passes valve gap 2 and upwards connects cursory 5.The sheath 7 of one hollow cylinder is set in valve gap 2 and the valve body 1 formed cavity, but the positive stop lug boss 71 of overcurrent is set in appropriate position, sheath 7 inwalls middle part.Seal 6 is loaded in the sheath 7 with gap and is between positive stop lug boss 71 and the valve gap 2, and promptly seal 6 freely moves up and down together with the inner chamber of valve rod 4 at sheath 7.Sliding sleeve 8 is loaded in the sheath 7 with gap and is between the round boss 12 of positive stop lug boss 71 and valve body 1 inner chamber intake-outlet 11 UNICOMs.
The upper and lower of sheath 7 was provided with opening 74 and following opening 73 respectively, sheath 7 forms flow channels 17 jointly with valve body 1 inner chamber, the round boss 12 of its underpart inner cylindrical surface and body cavity bottom plane is suitable, and its short transverse and valve gap 2 and valve body 1 base plane are suitable.
Intake-outlet 11 places of valve body 1 are provided with internal thread and connect, the central lines of the center line of its intake-outlet 11 and valve body 1, and it is fit to the installation of the solar water container of bottom water inlet and outlet.
Working procedure of the present utility model is as follows: on to solar water heater during water, sliding sleeve 8 at first is subjected to water impact and moves up at once and cross opening 72 on the shutoff positive stop lug boss 71, force current to pass the flow channels 17 that opening 81 and 73 enters body cavity of crossing of sliding sleeve 8 and sheath 7, then current enter the flow channel of valve gap 2 from the top through hole 74 of sheath 7, by the cavity in the valve gap 2 22, arrange to solar water container by suction pipe 3 at last.The flow channel of such setting can be protected rubbery sealed body 6 not to be subjected to the impact of current effectively and be in reposefully on the positive stop lug boss 71 of sheath 7; certainly also fundamentally eliminated to cause when hydraulic pressure is higher the brute force of rubbery sealed body 6 is impacted and closed water valve, stoped the normal difficult situation of going up water.Along with the rising of water level in the water tank, ball float drives rubbery sealed body 6 gradually with the sealing of the cavity in the valve gap 2, until sealing fully, stops to go up water automatically.
When using the hot water of solar water heater, open water valve, because suction function, force rubbery sealed body 6 to leave the sealing seat 21 of valve gap 2 and open water valve, simultaneously sliding sleeve 8 is dropped on the round boss 12 of valve body 1 intracavity bottom naturally, thereby hot water enters the flow channels 17 of valve body 1 inner chamber and the flow channels 76 of sheath lumen via suction pipe 3, valve gap 2, at the water outlet 11 of the flow channels 81 back rows that pass sliding sleeve 8 to valve body.This kind structural design has guaranteed that effectively body cavity and sheath lumen do not have impurity precipitable, so this valve has the characteristics of self-cleaning.
Second embodiment:
Referring to Fig. 2, difference on the present embodiment and first example structure is, valve body 1 intake-outlet 11 places are provided with internal thread and connect, the center line of its intake-outlet 11 is vertical with the center line of valve body 1, and a planar pair flat pair 13 is set in the bottom of intake-outlet 11, it is fit to the installation of the solar water container of side water inlet and outlet, and the bottom of intake-outlet 11 is provided with Vertical location and the screwing hermetic that a planar pair flat pair 13 is water control valves for convenience.Other structure is all identical with first embodiment, has not here just given unnecessary details.
For two embodiments, valve body 1 can adopt steel or high-low temperature resistant plastics, and valve rod 4 needs to adopt high-quality cold-drawn steel bar.
