Abstract
The utility model belongs to the hot-water heating valve field, particularly relating to a safety water saving valve for preventing the heating pipeline from leaking or the heating radiator from blowing out; in order to solve the accidents caused by the leakage of the heating water and the blowout of the heating radiator, the utility model consists of a valve body(8), a piston type valve core(10) and a compression spring(15), wherein,an outer middle part of the valve body(8) is double calabash-shaped; the valve body is provided inside with a piston hole(11), a front launder(6) and a back launder(13); the front and the back launders arranged side by side are respectively communicated with a transverse through hole(4), a transverse through hole(7) and a transverse through hole(12); the three through holes are arranged on the valve core; an end head of valve core on one end of a water inlet is provided with an axial direction blind hole(3) which is communicated with the three transverse through holes on the valve core and the front and the back launders in the valve body; the other end of the valve core is a cylinder of a hemicone(14); the other end of the valve core is pressed against an outer ring of a valve port(16); the leakage proof safety valve can automatically close a valve port, cut off the water supply and the backwater in time, prevent the heating water from flowing out and avoid the economic loss and the waste of water resources.
Description
Technical field:
The utility model 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 energy saving device of heating installation explosion.
Background technique:
Society goes up occurring the problem of heating pipeline leakage and radiator explosion in the heating system at present, does not take any safety to prevent measure, 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.
Summary of the invention:
The utility model provides a kind of heating system that is used for, and when 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, the anti-safety valve of letting out that reduces water resource waste and cause tremendous economic to lose.
The technical solution of the utility model is: a kind of anti-safety valve of letting out 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 double calabash shape 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 the middle-end piston hole also is provided with former and later two gutter channels 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 former and later two gutter channels of valve inner are connected.The spool the other end has half conehead, the conical surface of conehead 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.
The beneficial effects of the utility model are: in case take place to reveal or bursting accident, can close automatically and remain silent, in time cut off and supply water and backwater, prevent that heating installation water from continuing to run off, avoid causing economic loss and water resource waste.
Description of drawings:
Fig. 1 is the anti-sectional view of letting out safety valve:
Mark among the figure: 1, be the water intake pipe screw joint; 2, be back-up ring; 3, be blind hole in the valve core, 4, be cross through hole on the valve core; 5, dottle pin on the valve core; 6, be preceding gutter channel in the valve body; 7, be horizontal on the valve core
