Abstract

The utility model discloses a valve which can automatically close and is used for a solar water heater. The utility model is characterized in that a float chamber is arranged on the upper part of a valve body; the valve is driven to open and close by the sinking and floating of a float arranged in the float chamber; in an interface arranged on the water outlet end of the valve, a water outlet pipe extends into an air outlet pipe of a water storage tank of the solar water heater; the gap between the water outlet pipe and the air outlet pipe of the water storage tank is communicated with the float chamber through a hole arranged on the side of the bottom surface of the float chamber. When water enters, the water enters a water tank through a valve core and the water outlet pipe; when the water tank is full of water, the water enters the float chamber to enable the float to float through the gap between the air outlet pipe and a water inlet pipe and the hole arranged on the side of the bottom surface of the float chamber; a valve sheet is lifted to close through a connecting rod to reach the purpose that the water storage tank of the solar water heater is automatically closed when the water storage tank is full of water.

Description

A kind of valve

The utility model relates to a kind of valve, the particularly a kind of valve that can close automatically on the solar water heater water storage tank that is installed in.

Existing solar energy water-heater's inlet valve generally all is installed in indoor, when giving solar water heater inlet, must wait until from solar water heater and give vent to anger spill pipe when guiding to indoor signal tube flowing water, inlet valve can be closed, when just requiring the user to use, this wants Attended mode, not only the user has been caused waste of time, also caused waste water resources.

For addressing this problem, existing way is to be installed in the water storage tank from the solar water heater water tank bottom with ceramic seal gasket, rope chain, float, because of ceramic seal gasket is to seal by the method for pushing, when water heater has incrustation scale or other precipitate on valve block, just can make to push imprecision between the valve block and cause and leak, and this method could be installed after must transforming the prior solar water heater water storage tank, and the solar water heater that is using at present all can't be installed.

The purpose of this utility model is that a kind of improved valve will be provided, and it can be installed on any solar water heater water storage tank that steam outlet pipe arranged easily, and must not do any change to original solar water heater water storage tank.

The utility model is achieved in that on the top of valve and is provided with float chamber, there is an aperture at the center of float chamber bottom surface, there is a connecting rod that float is connected with movable valve block in the valve body in the aperture, one side in the float chamber bottom surface near the waterexit end is drilled with a bigger hole, this hole is connected with the waterexit end, waterexit end at valve, one interface that can join with solar water heater water storage tank steam outlet pipe is arranged, this interface communicates with hole on the limit, float chamber bottom surface, in interface central authorities a hole of leading to the valve body center is arranged, the outside that interface is stretched out by the metal tube that matches with its latus rectum in this hole, outlet pipe as valve, the port of outlet pipe is with the non-return silica gel sheath, with anti feedback.Give vent to anger as water storage tank and the passage of spilling water in hole on space between outlet pipe and the interface and the limit, float chamber bottom surface that communicates with it, have in the bottom of valve large, medium and small three with the float chamber bottom center concentric endoporus in hole, aperture passes to the valve body center and communicates with outlet pipe, on the step of aperture and mesopore formation, be provided with the ring packing mouth of a protrusion aperture, on the step of macropore and mesopore formation, be provided with a matrix block water plate, be provided with the passage of a plurality of apertures around this block water plate as water, one movable valve block is arranged in the pit of block water plate, this valve block is connected with connecting rod, macropore is provided with a tooth, with connecing in the pipe in the precession macropore block water plate is fixed.During installation, this valve intake pipe is put in the solar water heater water storage tank steam outlet pipe, and interface and steam outlet pipe are connected, float chamber is upwards installed; Below water intake with pass to after the water storage tank outlet pipe that safety check is housed is connected indoor.During use, open indoor inlet valve, because of solar water heater water storage tank water intake is equipped with safety check, water can only enter in the valve by the hole on the block water plate limit of this valve, enters water storage tank by outlet pipe again; When water storage tank water is full, water enters float chamber through the hole on the limit, float chamber bottom surface again by the space between water storage tank steam outlet pipe and this valve outlet pipe float is floated, the valve block of drivening rod and connecting rod lower end moves up, block the ring packing mouth, under the effect of float buoyancy and hydraulic pressure with valve closing.

The utility model is not because need the user to increase in-house operation, so easy to use.In addition, do not need the user that the water heater structure is changed during owing to installation, so the user can be installed on any solar water heater water storage tank that steam outlet pipe is arranged that is using easily voluntarily.

The utility model will be further described below in conjunction with accompanying drawing.
