Abstract

The utility model discloses an automatic water supply valve for a solar water heater. The utility model is characterized in that the inner part of a small thermal insulation barrel is provided with a float ball vertical motion device which is used for pushing and pulling the valve to open and close. The valve is arranged on an upper end cover of an inner barrel and is spaced with a distance with the water level of a water tank, and therefore, the influence of hot water in the water heater on scales and stones of the valve is small. The utility model has the advantages of small size, high sensitivity, and reliable motion. The utility model is also suitable for other water tanks.

Description

Water self-acting valve on a kind of solar water heater

Technical field

The utility model relates to water self-acting valve on a kind of solar water heater, is that a kind of volume is little, the solar water heater automatic water feeding of insulation, highly sensitive, reliable in action.

Background technique

Solar water heater automatic water feeding in the market, the secondary water tank that heat insulation type is bulky, cost height, wind resistance power be poor, it is single to install.Some devices that volume is little nearly all flood the water supply valve spool in the hot water, and at high temperature easily calculus does not make sensitivity reduction, the reliability of valve high and install and also can only narrow limitation be arranged in the side.

Summary of the invention

In order to overcome the two defective, the little insulation again of the utility model volume, high-temperature water calculus influence less to valve, install general.

The technological scheme that its technical problem that solves the utility model adopts is: reduce the float valve mechanicalness resistance that is adopted, improve valve flexibility sensitivity, thereby make that the ball float volume reduces, lever shortens, the mounting type that changes ball float and valve reaches practical purpose.

The beneficial effects of the utility model are: the insulation, volume is little, highly sensitive, versatility is good, easy for installation, simple in structure.

Embodiment

Ball float guide rail nut (1) ball float guide rod upper rail bolt (2) is installed in respectively on interior bucket (9) upper end cap center mounting hole in Fig. 1.Low mechanicalness resistance float valve (3) is installed in interior bucket (9) upper end cap one side mounting hole, and an I-shaped groove of valve (3) lever opening one end and ball float guide rod (11) plugs together.One end of ball float guide rod (11) inserts in ball float guide bar bolt (2) hole, and the other end inserts ball float guide rod lower rail porous piece (12) center hole.Weldering of outlet pipe (13) one ends or riveting are rotatably connected in ball float guide rod lower rail porous piece (12) and this end are being welded in interior bucket (9) end center mounting hole, and the other end stretches out shell (8) lower end cap center hole and is connected with the solar water heater inlet mouth.Air inlet overflow pipe (7) one ends are welded in interior bucket (9) one side mounting holes, and the other end stretches out shell and cooperates with air inlet overflow pipe screening seam circle (6).Insulation filler (10) is filled out every between shell (8) and interior bucket (9).

In embodiment illustrated in fig. 2, ball float guide rod (11) is equipped with a bolt pin with low mechanicalness resistance float valve (3) lever one end socket.

In Fig. 5 embodiment, spool nut (3), valve core seal ring (4), duplex font spool guide rod (5) is formed a duplexing font guide bar spool, valve rod tack one end is packed into, stretch out in the center osculum of waterexit end screw joint (7), cone one end that again porous spool stabilization (2) center hole is inserted in I-shaped guide bar spool cooperates with the water intake of waterexit end screw joint (7).The outer tooth of feed-water end screw joint (1) one end and waterexit end screw joint (7) spins, both seams are by rubber Mi Quan sealing (6), balance pivot bolt (8) has thread one end to revolve or is welded in the fulcrum screw of waterexit end screw joint (7) one ends, floating ball lever (10) opening has pin-and-hole one end insertion balance pivot bolt (8) to cooperate with duplexing font guide bar spool (5) guide rod socket, the pin (9) of will living again, pin go in the pin-and-hole of floating ball lever (10) pin-and-hole and balance pivot bolt (8) to rivet.
