Abstract
The utility model provides a built-in automatic water supply valve of solar water heater, which comprises a seat body with a built-in water hole and arranged inside a through hole of a water tank wall. A lower end of the seat body is provided with a threaded pipe joint, and an upper end of the seat body is threaded connected with a valve body. The upper end of the seat body connected with a rotary shaft of the valve body is provided with a linking rod. An upper end of the linking rod is connected with a float. The utility model is assembled with a water heater in a manner of insertion. The valve body and the linking rod as well as the float are arranged inside a water tank by the utility model through the seat body, the opening and closing of the valve body is controlled by the rotation of the linking rod driven by lifting of the float, and automatic control of water level of the water tank is achieved. The utility model has simple structure, convenient assembling, and reliable and safe working as the valve body is directly contacting with warm water inside the water tank and not affected by outdoor low-temperature freezing.

Background technique
Solar water heater is with advantages such as its energy-conservation and environmental protection, by use more and more widely.Solar water heater needs constantly to replenish cold water in water tank in normal using process.Its moisturizing control has manual and automatic dual mode.The automatic water supplement mode is with advantages such as its easy to use and water level precise controls, generally adopted, existingly be used for mainly containing the solenoid valve water replenishing device and paying a water tank water replenishing device of solar water heater automatic water supplement, its electromagnetic valve moisturizing utilizes solenoid valve and the supporting use of water level detector, because of the need power supply, so have the electric leakage safety problem, and be subject to temperature and water quality impact, cause Control Failure.Pay the water tank water replenishing device and be connected with water tank and control cistern water level,, and the relative volume of water tank is increased,, make the equipment cost increase again because of structure relative complex, installation and maintenance inconvenience etc. because of it is assemblied in water tank outside with the interior water tank of paying of establishing water control valve; And be disposed at the water tank outside owing to pay water tank, easily because of the sharp freezing cisco unity malfunction.
The model utility content
The purpose of this utility model is at the problems referred to above, and a kind of simple in structure, built-in automatic water compensating valve of solar water heater that configuration is convenient, safe and reliable is provided.
For this reason, the technical solution of the utility model is: the built-in automatic water compensating valve of a kind of solar water heater, it have be assemblied in the water tank wall through hole in establish the pedestal of water passage hole, the lower end of its pedestal is threaded pipe joint and protrudes from water tank wall, the upper end of its pedestal is through the valve body that has been threaded, be equipped with connecting rod in the rotating shaft of valve body, the other end of its connecting rod is connected with float.
In having, establishes valve body described in the utility model the valve casing that the mouth of a river is crossed on separation water-inlet cavity and water chamber plane, in the water chamber of valve casing with cross mouth of a river concentric be disposed with seal ring, in establish symmetrical fan-shaped water port fixed valve and in establish the rotating valve of symmetrical fan-shaped water port, its seal ring and fixed valve are assemblied in the front end through screw thread and valve casing rotating shaft cover that fix and that be provided with the side direction osculum, in the rotating shaft cover, be equipped with rotating shaft, it is forked and be connected with rotating valve that the front end of its rotating shaft is ∪ shape, and the rear end of rotating shaft is through the fixedly connected connecting rod of nut.
The technical solution of the utility model also comprises: be equipped with water outlet end at the valve body water outlet end and block up and be provided with radially osculum.
The utility model adopts the grafting fit, utilize pedestal that valve body and connecting rod and float are arranged in the water tank, lifting drivening rod rotation control valve body by float is opened and is closed, realize the automatic control of cistern water level, its apparatus structure is simple, easy to assembly, and owing to the interior warm water of valve body and water tank directly contacts, the influence that not freezed by outdoor low temperature, safe and reliable.
Description of drawings
Fig. 1 is built-in automatic water supplement valve arrangement of this solar water heater and water tank configuration schematic diagram;
Fig. 2 is pedestal and valve body and assembly structure plan view.
Embodiment
Provide as accompanying drawing 1, this water-feeding valve is made up of pedestal 1, the float 4 that is connected valve body 2, the connecting rod 3 that is connected with valve body 2 on the pedestal 1 and is fixed on connecting rod 3 upper ends.Its pedestal 1 is by assembling with water tank in the through hole that is inserted into water tank wall, and the seal ring on fitting surface is realized fitting tight, valve body 2 adopts rotating valve, opening and closing by the rotation that is installed in the connecting rod 3 in the valve rotating shaft of valve handled, and the rotation of connecting rod 3 then relies on float 4 controls of its upper end configuration.The suitable floating-tube type buoyancy aid that adopts elongated cylindrical of its float.
Fig. 2 provided the utility model valve body 2 concrete structure and with the concrete fit of pedestal 1 and connecting rod 3.Establish the valve casing 4 that the plane is crossed the mouth of a river and through the mouth of a river water-inlet cavity and water chamber separated in its valve body 2 has, valve casing 4 water chamber sides with cross mouth of a river concentric and set gradually seal ring 5, fixed valve 6 and rotating valve 7 by the outside of crossing the mouth of a river.The both sides end face of its seal ring respectively with cross that the inner side plane of actinal surface and fixed valve is sealed and matched outside the mouth of a river, be respectively arranged with unidimensional symmetrical fan-shaped water port on fixed valve and rotating valve, valve is in closed condition when stagger fully in the water port of two valves.The water chamber side of valve casing 4 with cross mouth of a river concentric is equipped with laterally disposed osculum through being threaded rotating shaft cover 8, the front end of this cover 8 of walking around is by interference fit seal ring 5, by being arranged at the groove mount valve 6 on the cover inwall.Be equipped with rotating shaft 9 in rotating shaft cover 8, it is forked that the front portion of rotating shaft 9 is ∪ shape, and the front end of its fork body places in the groove of rotating valve outer side surface setting, is used to make fixed valve closely to contact with the fitting surface of rotating valve, and realize the rotation of rotating valve.The back axle head of its rotatingshaft 9 is stretched out by the rotating shaft cover, and by nut 10 fixing assembling connecting rods 3.
