Abstract
The invention relates to a fire valve capable of automatically turning on and off under high pressure, which belongs to the field of flow automatic control equipment and is mainly applied to fire fighting. The fire valve mainly consists of a valve body and a control valve cap and comprises a valve body, a return spring, a valve element sleeve, a magnetic ring assembly, memory alloy, a heat insulating sleeve, a pressure relief hole, a water inlet cavity, a diaphragm assembly, a valve body, a valve cover, a communication pipe, a connecting piece, a magnetic cylinder assembly and a valve element assembly; the valve body comprises the diaphragm assembly in the valve body, the water inlet cavity working by matching with the diaphragm assembly in the valve body and a water outlet thereof; the valve cover is connected with the valve body through a bolt; the lower end of the valve element assembly is provided with a sealing sleeve; and the sealing sleeve can plug the pressure relief hole on the valve body. The fire valve fills the blank that self-operated fire valves which can be automatically turned on and off and work under high pressure do not exist at present.
Description
Technical field
A kind of fire valve of automatic on-off under high pressure belongs to flow automatic control equipment field, is mainly used in fire-fighting.
Background technique
Existing fire prevention equipment mainly is installed in office building, the office building.This disposable glass bulb formula spray equipment is though when fire takes place, raise with ambient temperature; The sprinkling fire water of breaking automatically; But after fire was put out by water, owing to can not close automatically, a large amount of water still sprayed incessantly; This technology is not only wasted precious water resource, and can cause irretrievable loss to the goods and materials of some occasions.The automatic on-off fire prevention that occurs recently, though can remedy this defective, because structural reason but can not be operated in the high pressure fire fighting water system.
Summary of the invention
The object of the invention provides a kind of fire valve of automatic on-off under high pressure.
Technological scheme of the present invention realizes like this: automatic fire valve mainly is made up of valve body and control bonnet; Comprise valve body, reset spring, valve core housing, magnetic ring component, memory alloy, collet rushes down and presses hole, water-inlet cavity, diaphragm unit, valve body, valve gap, connecting tube, link, magnetic column assembly, mangetic core assembly; Said valve body by the diaphragm unit in the valve body, with the valve body of diaphragm unit cooperating in water-inlet cavity and water outlet thereof; Water outlet cooperates the flow of control valve with diaphragm unit, said valve gap is connected with valve body through bolt, and connecting tube is arranged above the valve gap; One in connecting tube communicates with the valve gap upper plenum; What other end and valve body were interior is communicated with connecting tube, and the other end of the connecting tube in the valve body is communicated with the water outlet of valve body with the spatial communication of rushing down upper end, pressure hole, the other end that rushes down the pressure hole; The lower end of said mangetic core assembly is equipped with stuffing box gland; Stuffing box gland can block to rush down presses the hole, thus the keying of control valve, in the valve core housing that mangetic core assembly is inserted in valve body is connected; The embedded magnetic column assembly in mangetic core assembly top, the centre of mangetic core assembly have the equalizing orifice of end side surface from top to bottom; Said control bonnet is by being close to the collet that is enclosed within the valve core housing outside, the memory alloy that the collet outside is with; Reset spring is withstood in the magnetic ring component that withstand the memory alloy upper end, magnetic ring component upper end; The interior top of chamber of bonnet is withstood in the reset spring upper end; The bottom of bonnet is connected with the link that valve core housing cooperates through screw thread, and the bottom of link is connected with valve body through screw thread again; Said magnetic column assembly and magnetic ring component are made up of some monomer magnets respectively.
The invention has the beneficial effects as follows, filled up the blank of the fire valve under the be operated in high pressure conditions that does not have self-powering type, automatic on-off at present; Adopt the diaphragm unit structure, not only can improve water flow, and improve the reliability of system works.
Description of drawings
Fig. 1 is the principle master map.
