Abstract

The utility model relates to a water-stopping deflation valve for a radiator, particularly parts for heating equipment of dwelling houses. The utility model comprises the existing deflation valve which is composed of a valve body and a valve needle. The utility model has the improvement that one end of the interior of the radiator, which is extended by the valve body, is connected with a water-stopping device which is composed of a float ball, a float ball containing chamber and a venthole, wherein the specific gravity of the float ball is lighter than water; the lower end of the float ball containing chamber is provided with an air inlet hole and a water inlet hole, and the upper end is provided with an air outlet hole of which the diameter is smaller than that of the float ball. The utility model has the advantages that the water-stopping deflation valve for a radiator can discharge superfluous air in the radiator without discharging water in the radiator; even if a small amount of water is flowed out, the utility model does not satisfy the dosage of hot water which water stealing people need, and thus, the utility model cancels the desire of continuatively stealing the water, reduces the loss of heat supplying people and ensures the safety of supplying heat.

Description

The radiator bleed valve that blocks water

Technical field

The utility model relates to the component of residential heating equipment.

Background technique

At present, on the radiator in the heating system, major part also all is equipped with bleed valve, be used to discharge the heating cycle when beginning to the radiator water filling, or in the lack of water process that causes of additional heating stage a variety of causes by the air of water seal at the radiator internal upper part.Existing vent valve is installed on the radiator upper side plug.Bleed valve is made up of valve body and needle, one end of valve body has the outside thread that cooperates with plug, there is vent in the valve body axle center, vent excessively enlarges through cone shape hole at the valve body medium position, there is one section internal thread the vent outer end, is used to install needle, the front end of needle for valve body in the excessively taper that matches of cone shape hole, the column part diameter of needle tapered rear is less than valve body inner bore, and the bigger part of axial bore diameter communicates in there are radially vent hole and valve body in the valve body middle part.When the rotation needle, when the tapered front end of needle and valve body inner conical surface were left, the inside and outside formation passage of radiator, the pressure in radiator be during greater than barometric pressure, the outside exhaust of radiator.From the structure of this bleed valve as can be seen, it can not only be exitted, and can discharge water equally, and this brings the convenience of stealing hot water just for the low people of some moral level, and the heat supply loss that causes thus is more common to the dispute of the influence of adjacent resident family heating and initiation.

Summary of the invention

The purpose of this utility model provides a kind of radiator bleed valve that blocks water, and is used for overcoming prior art radiator bleed valve above shortcomings.

The utility model comprises existing by valve body, the bleed valve that needle is formed, the improvement of being done is that the end in valve body stretches to radiator is connected by ball float, the ball float receiving cavity, the device that blocks water that vent is formed, wherein the proportion of ball float is lighter than water, and there are air inlet, water inlet in ball float receiving cavity lower end, and there is the air outlet hole less than floating ball diameter the upper end.

Good effect of the present utility model is to rotate when needle retreats needle to emit unnecessary air in the radiator, and can not emit water in the radiator, even if there is a spot of water to flow out, but do not satisfy the surreptitiously consumption of water person's hot water, given up continuing to steal the desire of water, reduce heating person's loss, ensured the safety of heating.

Description of drawings

Accompanying drawing is the whole main sectional view of looking of the utility model.

Embodiment

Adopt the existing valve body 1 that comprises, the radiator bleed valve of needle 2.On the outside thread of valve body 1 rear end, connect the crust of the device 3 that blocks water that comprises that horizontal, vertical two sections cylinders constitute.There is vent 4 at the one section center horizontal at shell, and the vent in the diameter of vent and the valve body 1 is identical, and there are internal thread that matches with valve body 1 and the outside thread that cooperates with plug in the end.The vertical center, one section upper end of shell has vent to communicate with one section vent of horizontal stroke.The vertical pars infrasegmentalis of shell has ball float receiving cavity 5, and the diameter of ball float receiving cavity is greater than floating ball diameter 2mm, and height is 2 times of diameter, and circular cone or spherical excessive face are arranged between ball float receiving cavity madial wall and the air outlet hole.There is internal thread the lower end of ball float receiving cavity, screw thread is arranged, axially the shutoff of a plurality of apertures is arranged with an outer surface, is contained in the receiving cavity lower end, and ball float 6 is enclosed in the receiving cavity.Ball float can be the metal or the baton round of hollow, and diameter should be selected between 8-10mm.。

The utility model the installation process on the radiator be radiator plug 7 on the original tapped hole that common bleed valve is installed enlarge, make it and the screw thread of the crust of the device that blocks water is complementary, the vertical portion branch of crust of the device of blocking water in the portrayal of the end face of the crust of the device lateral part that blocks water is in mark vertically downward, the crust of the device that blocks water is contained in the inboard of plug, again plug is contained on the radiator, and the crust of the device that guarantees to block water vertical one section vertically downward, valve body 1 is tightened on the internal thread of the crust of the device 3 that blocks water again, promptly finishes installation of the present utility model.

Working procedure of the present utility model is: when unnecessary air is arranged in the radiator, the rotation needle makes it to retreat, air-passage opening, gas is emitted gradually, and water level rises in the radiator, the water inlet of ball float receiving cavity, the air outlet hole place that ball float is pushed into by water, because buoyancy and the effect of air-flow fast of ball periphery, air outlet hole is closed substantially, and water can not be flowed out.

Claims

The radiator bleed valve that blocks water, comprise existing valve body (1), needle (2), it is characterized in that: the end in valve body stretches to radiator is connected by ball float (6), ball float receiving cavity (5), the device that blocks water that vent (4) is formed, wherein the proportion of ball float is lighter than water, there are air inlet, water inlet in ball float receiving cavity lower end, and there is the air outlet hole less than floating ball diameter the upper end.
