Abstract

The utility model relates to an automatic valve closure device, in particular to a device applied in solar water heaters in which the valve can be automatically closed when the water is full, which comprises a valve connected to the water charging pipe. A handle is connected on the valve stem, in which one end is connected to a return spring, and the other end is connected to a strut divided as two parts hinged together. An automatic closing valve handle connected on the link point is in fixed connection with a water-containing plate. The overflow pipe is disposed above the water-containing plate. In the utility model, the automatic closure of the water charging valve is implemented with the adoption of the mechanical structure. When the water is filled, no people are required to watch. The utility model is very reliable, which is suitable to install for indoor use with convenient maintenance.

Description

Water self acting stop valve on the solar water heater

Technical field

The utility model relates to a kind of device of automatic-closing valve, especially a kind of solar water heater that is used for, device that can automatic-closing valve behind the filling up water.

Technical background

At present, the user of solar water heater is more and more, because that the water tank of solar water heater is installed in is outdoor, for the situation of monitoring watering, general adopt two kinds of methods: a kind of is the variation of adopting the electronic sensor sensed water level, sends chimes of doom after water is full or control electromagnetic valve is closed; Another kind is received overflow pipe indoor, judges by observing overflow pipe whether water tank is full.Electronic sensor is easy to use, but the cost height, outdoor electronic section is aging easily, and maintenance was also inconvenient when fault was arranged.Though the overflow pipe cost is low, maintenance is convenient, needs always in the process of last water that the someone observes, otherwise is easy to cause waste.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, maintenance is convenient, need not manually to wait for water self acting stop valve on the solar water heater that can close automatically behind the filling up water.

For achieving the above object, the utility model adopts following technological scheme:

The water self acting stop valve comprises the valve that is connected on the water inlet on the solar water heater described in the utility model, connect handle on the valve handle of valve, one end of handle connects return spring, the other end connects pole, pole is divided into hinged two-part, the articulating point place connects the self acting stop valve handle, and the self acting stop valve handle is fixedlyed connected with water receiving disc, and overflow pipe is positioned at the top of water receiving disc.

Be fixed with the pole backing pin on the pole.

The mechanical structure that all adopts the utility model realizes closing automatically water supply valve,, need not the someone during last water and keep the marquis, good reliability suitablely is installed in indoor use, and maintenance makes things convenient for.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the present utility model when valve closing;

Fig. 2 is the structural representation of an embodiment of the present utility model when last water.

Embodiment

As shown in drawings, the water self acting stop valve is mounted in indoorly on the solar water heater described in the utility model, is connected on the water heater water inlet.It is box-like that outward appearance is.Its essential structure is, a ceramic water nozzle valve 4 is installed on water pipe 2, pacifies a return spring 5 in the upper end of handle 6, and lower end and pole 7 are hinged.Pole 7 be divided into hinged about two sections, the articulating point place connects self acting stop valve handle 8, self acting stop valve handle 8 is fixedlyed connected with water receiving disc 9, overflow pipe 3 is positioned at the top of water receiving disc 9.

When this valve was in closed condition, pole 7 was the half-lap shape, and return spring 5 is contraction-like.During last water, will carry on the self acting stop valve handle 8, make pole 7 be flat (be fixed with pole backing pin 10 on the pole 7, avoid pole is overdrawn), return spring 5 is strutted, ceramic core water nozzle valve 4 is opened by handle 6.Behind the filling up water, the current of overflow pipe 3 advance water receiving disc 9, and the weight of water adds that the lower punch power of water bends pole 7, makes it lose support force.Return spring 5 shrinks rapidly under unsupported situation, moves handle 6 to closed condition, finally reaches the purpose of closing automatically.In addition, water receiving disc 9 also can be a small-sized bucket, and the bottom has weep hole, so that spilling water is discharged.

Claims

1, water self acting stop valve on the solar water heater, comprise the valve (4) that is connected on the water inlet, it is characterized in that: connect handle (6) on the valve handle of valve (4), one end of handle (6) connects return spring (5), the other end connects pole (7), and pole (7) is divided into hinged two-part, and the articulating point place connects self acting stop valve handle (8), self acting stop valve handle (8) is fixedlyed connected with water receiving disc (9), and overflow pipe (3) is positioned at the top of water receiving disc (9).

2, water self acting stop valve on the solar water heater according to claim 1 is characterized in that: be fixed with pole backing pin (10) on the pole (7).
