Abstract

The utility model relates to a water filling automatic closing device of a solar water heater, which consists of a water filling pipe, a floating-ball valve, a water supply pipeline, a water trough, a water discharging valve and a water overflow pipe entry. The upper part of the water trough body is provided with the water overflow pipe entry, and the water overflow pipe entry is communicated with a water overflow pipe on a solar water bucket. The floating-ball valve is arranged on the lower part inside the water trough, one end of the floating-ball valve is communicated with the water supply pipeline, and the other end is communicated with the water filling pipe on the solar water bucket. The water discharging valve is arranged below the water trough body and can be used for discharging the surplus water inside the water trough. Under the state that no water is arranged inside the water trough, a floating ball of the floating-ball valve drops off, and the floating-ball valve stays at an opening state, so water can be filled into the solar water bucket. When the water bucket is fulfilled with water, the water overflows out of the solar water bucket and flows into the water trough through the water overflow pipe, and under the effect of the floating force, the floating ball of the floating-ball valve floats to close the floating-ball valve, so the water filling into the solar water bucket can be stopped. The water filling automatic closing device of the solar water heater has simple structure, convenient application and low manufacturing cost.

Description

Water self closing device on the solar water heater

Technical field:

The utility model relates to the pipeline control device, relates in particular to water self closing device on the solar water heater.

Background technology:

Gong Ying water-supply valve of solar water heater adopts ball valve or quick opening valve more in the market, by manually-operated handle manual-lock valve.During use, open water supply valve and need the people behind the door and keep an eye on, treat overflow pipe flowing water after, close water supply valve again.Since on the solar energy water time long, do not leave when people fill with water through being everlasting sometimes, and forget and close water supply valve, treat that bucket water is filled with after, unnecessary water overflows, and causes the waste of water resource.Also have water controller on some electronic types in the market, but the water-supply apparatus complex structure of this electronic type structure, the cost height just can not use when having a power failure, and when being damaged, keep in repair also cumbersomely, so the user is to this device and not quite approve.

The utility model content:

The purpose of this utility model is, overcomes the part of the deficiencies in the prior art, and water self closing device on the solar water heater a kind of simple in structure, easy to use is provided.

Water self closing device on the solar water heater described in the utility model, including tank, overflow pipe access port, float-ball type valve and draining valve constitutes, be provided with the overflow pipe access port on the top of said tank cell body, the overflow pipe on overflow pipe access port and the solar energy bucket is communicated with.The inside of said tank by under the position be provided with the float-ball type valve, an end and the water supply line of said float-ball type valve are connected, the upper hose on the other end and the solar energy bucket is communicated with.Be provided with draining valve below the tank cell body, unnecessary water in tank can be used to drain.Water self closing device on the solar water heater described in the utility model, under the anhydrous state, the ball float of float-ball type valve falls in tank, and the float-ball type valve is in opening, and this moment can water filling in the solar energy bucket.When filling with bucket, spilling water in the solar energy bucket flows in the tank by overflow pipe, and under buoyancy, the ball float of float-ball type valve come-up is closed the float-ball type valve, stops water filling in the solar energy bucket.The utility model is simple in structure, and is easy to use, cheap for manufacturing cost, improves getting final product on the basis of water on the existing solar energy a little.

Description of drawings:

Accompanying drawing is the structural representation of water self closing device on the solar water heater described in the utility model.1-upper hose 2-float-ball type valve 3-water supply line 4-tank 5-draining valve 6-overflow pipe access port

The specific embodiment:

Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: water self closing device on the solar water heater described in the utility model includes upper hose 1, float-ball type valve 2, water supply line 3, tank 4, draining valve 5 and overflow pipe access port 6 and constitutes.Said tank 4 is main components of the present utility model, is set to the form of cylindrical bucket usually.Top at said tank 4 cell bodies is provided with overflow pipe access port 6, and the overflow pipe on overflow pipe access port 6 and the solar energy bucket is communicated with.The inside of said tank 4 by under the position be provided with float-ball type valve 2, an end and the water supply line 3 of said float-ball type valve 2 are connected, the upper hose 1 on the other end and the solar energy bucket is communicated with.Be provided with draining valve 5 below tank 4 cell bodies, unnecessary water in tank 4 can be used to drain.Water self closing device on the solar water heater described in the utility model, under the anhydrous state, the ball float of float-ball type valve falls in tank, and the float-ball type valve is in opening, and this moment can water filling in the solar energy bucket.When filling with bucket, spilling water in the solar energy bucket flows in the tank by overflow pipe, and under buoyancy, the ball float of float-ball type valve come-up is closed the float-ball type valve, stops water filling in the solar energy bucket.The utility model is simple in structure, and is easy to use, cheap for manufacturing cost, improves getting final product on the basis of water on the existing solar energy a little.
