Abstract

The utility model provides an automatic water feeder composed of a floating ball type one-way valve, which is characterized in that the automatic water feeder is composed of an enclosed water tank, the floating ball type one-way valve and an overflow valve, wherein, the floating ball type one-way valve mainly comprises a valve casing, a ball seat, an inner sleeve, a floating ball, a buffer fender, etc. which have simple structure and is not easy to generate failure and is free from the limitation and the influence of the water supply pressure, and the maintenance and the use are convenient. The utility model has the advantage that the automatic water feeder is suitable for various water tanks and water heaters, so the utility model is especially suitable for solar water heaters of the high and high layer buildings, etc.

Description

A kind of automatic loading water device

The utility model belongs to automatic filling device.

In existing automatic loading water, the water storing device, as various water storage boxs, water heater etc., the devices such as ball float, lever and compression type valve that adopt more, and what adopt in circulating water heater is the spring one-way valve, it needs the operator when using water heater, at first open outlet valve and exit and discharge water, and then open into water heating.And it needs certain pressure of supply water, could use extremely inconvenient to the water tank water filling.And these automatic loading water devices must be installed in closed tank inside, it is complex structure, maintenance difficult not only, particularly to the water-supply apparatus of the solar water heater that is installed in eminence and roof, when breaking down, keep in repair very difficultly, in most cases need the water heater dismounting could be repaired.

The purpose of this utility model is to overcome the deficiency and the shortcoming of above-mentioned automatic loading water device, provides a kind of pressure of supply water that is not subjected to limit, and is simple in structure, is difficult for producing fault, and operation and maintenance is the automatic loading water device easily.

The automatic loading water device that float-ball type one-way valve provided by the utility model is formed.It comprises closed water tank, it is characterized in that also being included in the float-ball type one-way valve of installing on the water tank inlet, and the relief valve that is installed with in tank top.

The automatic loading water device that above-mentioned float-ball type one-way valve is formed, described relief valve by under lead valve body, float, upper valve body, valve seat, valve gap and valve body pin etc. form; Described float is installed in down among the guiding valve body, on the following guiding valve body of the lower end of float the valve body pin is installed, and the guiding valve body is connected within the upper valve body; Valve seat is contained in the top of float, upper valve body upper end, and be connected by valve gap and fix its valve seat on the upper valve body; Center at valve gap, valve seat is provided with exhaust port.The float-ball type one-way valve of above-described automatic loading water device.It comprises the valve casing that is installed on the supply channel, there is the screw thread of connecting pipeline at the outside two ends of described valve casing, be provided with the seam step in inside, comprise also on the step that two water ports are arranged at a ball seat, interior cover, ball float and cover top, above the ball float of center, in put and adorning the buffering fender; Cover is fixedlyed connected with valve casing by screw thread in described; Described ball float is located on the water port that is placed on ball seat.

By the enforcement of technique scheme of the present utility model, use the float-ball type one-way valve not to be subjected to the restriction of its pressure of supply water at aspects such as water storage and waters and influence, and normally water filling and water.For various water storage boxs and water heater, the automatic loading water device that it provides can be realized automatic loading water, and it is simple in structure, is difficult for producing fault, maintenance and easy to use.Simultaneously, prevented that when watering is cut off the water the water backflow in water storage box or the water heater from running away, guaranteed the water of water storage box.

Describe exemplary embodiments of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of float-ball type one-way valve;

Fig. 2 is the structure plan view of float-ball type one-way valve;

Fig. 3 is the automatic loading water device schematic representation that band float-ball type one-way valve, relief valve are formed;

Fig. 4 is the structure of relief valve schematic representation.

Fig. 1, Fig. 2 float-ball type one-way valve are two crescent shape water ports 6 by the seam step 2 in valve casing 1, the valve casing, ball seat 3, interior cover 4, ball float 5, interior cover top, and composition such as buffering fender 7 etc.The outside two ends of its valve casing are provided with the screw thread of connecting pipeline, are adorning ball seat on the stopping table in valve casing, and ball float is placed on the mouth of water port, ball seat center 8.Cover is by being threaded in the valve casing in described, puts in above ball float a buffering fender is housed.

Fig. 3 is the automatic loading water device, and it is made up of a closed water tank (perhaps water heater tank) 9, float-ball type one-way valve 10 and relief valve 11.The float-ball type one-way valve is installed on the water intake of water tank, and perhaps among the intake pipe, its relief valve is installed in the top of water tank.

Fig. 4 is the relief valve of float-ball type automatic loading water device, it by under lead valve body 12, float 13, upper valve body 14, valve seat 15, valve gap 16 and valve body pin 17 etc. form.Described float is installed in down in the guiding valve body, is installed with one and is used to limit the descending thrust valve body pin of float on the following guiding valve body of the lower end of float.The guiding valve body is connected within the upper valve body, valve seat above float, upper valve body upper end, and be connected by valve gap and fix its valve seat on the upper valve body.Be provided with exhaust port 18 at the center of valve gap, valve seat.

When to the water tank water filling, through float-ball type one-way valve 10, water with ball float jack-up wherein after, intake in the water tank 9 by meniscate water port 8, to the water tank water filling.The gap of air in the injecting process in the water tank between float and following guiding valve body 12, the central row pore 18 of valve seat 15 and valve gap 16 is discharged water tanks.

When the water liquid level of water tank was raised to certain altitude, float 13 began to rise, and the upper end sphere of float and center hole 18 closures on the valve seat.At this moment, along with the continuation of the liquid level of water tank is risen, the water pressure in the water tank increases, and when the pressure of supply water balance of the below of the ball float in its pressure and the float-ball type one-way valve, its ball float 5 falls on the return of serve 3, stops to the water tank water filling.

And when when supply channel stops to supply water, the float-ball type one-way valve will stop the water in the water tank to reflux by pipeline, realize the water storage effect of water tank.

The automatic loading water device of float-ball type one-way valve described in the utility model and its composition is adapted to the use of various closed water tanks, water heater, is adapted to the use of the solar water heater of high-rise building use especially.
