Abstract

The invention relates to a valve in hot-water heating system, in particular to a safety anti-leakage valve for preventing the leakage of a heating pipeline or the blowoff of a heating radiator. The heating pipeline is often leaked or the heating radiator is often blown out in a heating system, resulting in the economic losses due to heating water loss and the fire, up to more than RMB 2000 millionyuan per year in the heating period, and accordingly, more than 600 million ton of fresh water is wasted. For the purpose, the safety anti-leakage valve adopts the technical proposal that the safetyanti-leakage valve comprises a valve body (8), a valve core (10) and a spring (14); wherein, a middle part of the valve body is calabash shaped, a piston hole (11) is arranged in the valve body and the valve core (8) is of piston type. The anti-leakage valve can close a valve port automatically and cut off water supply and water return sources on time, when the heating pipeline is leaked or the heating radiator is blown out, for preventing the heating water loss, reducing the economic losses due to the flood and realizing the purpose of safe and water saving. The valve in hot-water heating system can be popularized for obvious benefit.

Description

Anti-leakage valve

A kind of in heating system, prevent that heating pipeline from leaking and the safety valve of radiator explosion.

Technical field:

Patent of the present invention belongs to hot-water heating valve class, is specifically related to a kind of heating pipeline that prevents and leaks and prevent the safety protection and the water saving fixtures of radiator explosion.

Background technique:

Society goes up often occurring the problem of heating pipeline leakage and radiator explosion in the heating system at present, prevents measure without any safety, in case go wrong, just there are a large amount of heating installation current to lose, suffer heavy losses water logging resident family, also to bring disaster to neighbours downstairs, cause economic loss and neighbours' contradiction.Also cause simultaneously the dispute and the contradiction of the reparations of user and Central Heating Providing merchant economic loss, influence social stability and unity.Big mishap all can appear in the annual whole nation in heating system countless.Estimation according to investigations, the economic loss that causes is become homeless up to more than 2,000,000,000 yuan of RMB at the heating installation current in the annual whole nation, and the waste freshwater resources just have more than 600,000,000 ton.

Summary of the invention:

Patent of the present invention provides a kind of heating system that is used for, and when heating pipeline leakage and radiator explosion occurring, can carry out automatically and close, and in time cuts off heating installation water and outflows in a large number, reduces water resource waste and because the anti-leakage valve of tremendous economic that floods cause loss.

The technological scheme of patent of the present invention is: a kind of anti-leakage valve that prevents heating pipeline leakage and radiator explosion, to form by valve body, spool, spring, and described valve body profile two ends are provided with the hexagonal body, and the middle part is the cucurbit shape.Valve body is built-in with spool and spring, and two ends are respectively arranged with the pipe screw joint of intake-outlet in the valve body, and middle-end is piston hole and is provided with gutter channel in the valve body, and is connected with spool cross through hole in the valve body respectively.Described spool is a piston cylinder operator, and spool places the piston hole in the valve body, and there is an axial blind hole spool termination that is positioned at water intake one end, and the cross through hole on this blind hole and the spool and the gutter channel of valve inner are connected.The spool the other end has a hemicone, the conical surface of cone can with airtight cooperation of circular cone valve port of valve body water outlet inboard, described spring is a pressure spring, its headgear is put in cone cylinder body outside, the other end is propped up and is withstood on valve port outer shroud place.

Description of drawings:

Fig. 1 is the sectional view of anti-leakage valve;

Mark among the figure: 1, be the water intake pipe screw joint; 2, be back-up ring; 3, be valve core one end blind hole; 4, be cross through hole on the valve core, 5, be dottle pin on the valve core; 6, be gutter channel in the valve body; 7, be cross through hole on the valve core; 8, be valve body; 9, be hollow in the valve core; 10, be spool; 11, be middle-end piston hole in the valve body; 12, be cross through hole on the valve core; 13, be the valve core head hemicone; 14, be spring; 15, be valve port; 16, be the water outlet pipe screw joint.

Embodiment:

Be described further below in conjunction with embodiment;

Referring to Fig. 1: being a kind ofly to prevent that heating pipeline from leaking and the anti-leakage valve of radiator explosion, is by valve body (8); Spool (10); Spring (14); Form. it is characterized in that: valve body (8) profile two ends are provided with the hexagonal body, the middle part is Pear Shaped, valve body (8) is built-in with spool (10) and the interior two ends of spring (14) valve body are respectively arranged with intake pipe inipple (1) and water outlet pipe screw joint (16), the valve inner middle-end is piston hole (11), and be provided with gutter channel (6), and respectively with valve body in spool cross through hole (4), (7), (12) be connected, spool (10) is a piston cylinder operator, spool (10) places the piston hole (11) in the valve body, there is an axial blind hole (3) spool (10) termination that is positioned at water intake one end, in cross through hole (4) on this blind hole (3) and the valve core and the valve body on gutter channel (6) and the valve core in cross through hole (7) and the valve core on hollow (9) and the valve core cross through hole (12) be connected, spool (10) the other end has a hemicone face (13), half cone dignity (13) can with airtight cooperation of circular cone valve port (15) of valve body water outlet inboard, spring (14) is a pressure spring, its headgear is put in conical surface cylindrical body outside, the other end is propped up and is withstood on valve port (15) outer shroud place, pressure spring (14) leans against on the back-up ring (2) of water inlet spool (10), its pressure just makes cone face (13) and valve port (15) be in normally open, this embodiment's anti-leakage valve is installed in heating system on the heater inlet pipe road, the front end of many radiators, and the safety check on the water return pipeline of radiator rear end is used, and its working procedure is: pressure make heating installation water from pipe joint (1) flow into blind mouthful (3) through cross through hole (4) and in by valve body gutter channel (6) flow into spool cross through hole (7) again and enter the radiator heat supply through spool hollow (9) outflow spool cross through hole (12) process valve port (15) intake channel joint (16).When pipeline leakage or radiator explosion problem appear in the water outlet rear end of anti-leakage valve; heating installation water outflows in a large number; water outlet one end pressure sharply descends; this moment, the pressure of water-supplying mouth made water promotion piston valve core (10) pressure spring (14) make hemicone (13) and valve port (15) closure fast; the while closure of check ring; the water source outflow of water supply in the cut-out heating pipeline and backwater in time; protect a large amount of heating installation water not leak; avoid reaching the purpose of safe water-saving because the tremendous economic that floods caused is lost.After fault was got rid of, the two ends of anti-leakage valve reached isostasy, and spring (14) is pushed piston valve core (10) to back-up ring (2), and the heating installation water in the heating pipe-line system begins normal circulation work.
