Abstract
The invention relates to a high-pressure sprinkler water control valve which can be controlled automatically or manually. The water control valve has a cylindrical shape, and has a pressure-driven piston structure. Water inlet and water outlet adopt Rc1'' interface, and a water supply flow reaches 300L/min. A sealing ring is fastened at a valve core water inlet side in a bushing by using a pressure plate. A water inlet interface and a water outlet interface are connected with a valve body water inlet and a water outlet through sealing gaskets. A filtering block is embedded in the valve body. An inclined-hole screw plug is fastened in an outlet section hole of the valve core. A spring is sleeved between the valve body and the valve core. O-shaped sealing rings are sleeved on valve core outer circle and water outlet interface inner hole. Under the effect of both inlet water thrust and the spring, the valve core is in a sealed state. When the valve is opened, pressurizing water is delivered into a driving chamber between the valve core and the valve body, such that the valve core moves towards the water inlet side under pushing and leaves a sealing cone, and water supply is turned on. The valve provided by the invention belongs to the field of fire extinguishing. With risk, a hidden danger of false water delivery during water pressure fluctuation due to the low rated working pressure of a common sprinkler alarm valve is solved, and impact damage of water hammer while opening/closing is reduced. The high-pressure sprinkler water control valve is composed of the valve body, the valve core, the water inlet interface, the water outlet interface, the sealing ring, the sealing gaskets, the pressure plate, the bushing, the O-shaped sealing ring, the spring, the filtering block, and the inclined-hole screw plug. The valve provided by the invention has wide application prospect in fields such as electric power, chemical industry, metallurgy, warehousing, and libraries and archives.
Description
Technical field
The present invention is novel to be related to a kind ofly for fire protection sector, and rated operating pressure reaches 16MPa, and inside nominal diameter is DN25mm, and water supply flow reaches 300L/min, and the piston pressurization drives structure is adopted in design, and sealing means is closed in following current.Be core control valve one high pressure deluge alarm valve in high pressure, the middle pressure fine water mist fire-extinguishing system, belong to the fire-fighting fire extinguishing field.
Background technology
Existing deluge alarm valve, rated operating pressure is on the low side, is 1.2MPa, 2.5MPa; Material: cast iron/steel, intensity is lower.Be unsuitable for long distance, the thin water mist fire-fighting application requirements of multizone; Conventional deluge alarm valve bore is DN200, DN150, and the pipeline network construction cost is large, occupy larger space.
Traditional deluge alarm valve opening ways is decompression starting: the flap assembly is opened water outlet during the control chamber pressure decreased.When water pressure fluctuations, deluge alarm valve control chamber pressure is kept and is incessantly namely caused mistake sprinkling accident, and impact just produces, causes water stain infringement.In electric power, chemical industry, metallurgy, storage, book and file protection place, misoperation occurs often, causes unnecessary economic loss.
Present deluge alarm valve, great majority belong to lever, diaphragm type structure.The flap termination was huge to the bump of valve body when the lever deluge alarm valve was opened, and valve body is broken.During diaphragm type deluge alarm valve unlatching work, flap is non-all to be opened, and the loss of flood peak is large, and the barrier film pressure-bearing stretches at ordinary times, responsive to sharp objects such as scum, finger stones, easily scratches cracking, and service life is short.What conventional deluge alarm valve can't satisfy high-pressure fine water mist fire-extinguishing system spurts the control requirement, has been unsuitable for escorting to new industry.
Summary of the invention
In order to fill up the blank of domestic 16MPa level high pressure deluge alarm valve, in order to solve deluge alarm valve false action-proof performance, the infringement of elimination impact of water hammer, satisfy the 300L/min output, the present invention is novel to provide a kind of high pressure deluge alarm valve, and its rated operating pressure is 16MPa, nominal diameter 25mm, minimum starting pressure is 0.3MPa, the loss of flood peak≤0.02MPa, opening time＜15s; The novel employing piston pressurization of the present invention type of drive, effectively the conducting sectional area is large, compact conformation; Adopt following current to close design of Sealing Structure, utilize water inlet thrust and the acting in conjunction of spring that spool is closed, the inclined hole plug screw is set gets rid of in real time the remaining water of actuator chamber, overstocked, guarantee water pressure fluctuations or when cutting off the water supply valve do not open by mistake and open; Valve body Φ 1.5mm inlet opening cooperates with inclined hole plug screw Φ 0.8mm relief hole, reaches the slow supercharging of actuator chamber, pressure release, make that spool slow is opened, Slow Close, eliminated water hammer to valve after the infringement of pipeline and annex; In height, middle pressure fine water mist fire-extinguishing system, be with a wide range of applications.
The present invention is novel be achieved in that high pressure deluge alarm valve by: water supply connector, gasket seal, pressing plate, sealing ring, lining, spool, O RunddichtringO, valve body, water out adapter, spring, inclined hole plug screw, filter block form; Water supply connector is connected with the intake-outlet of valve body respectively by gasket seal with water out adapter, sealing ring is enclosed within on the lining and is anchored on the spool influent side by pressing plate, spring housing is at valve body and valve core chamber, the O RunddichtringO is enclosed within spool cylindrical and the water out adapter endoporus, the filter block interference is assemblied in the valve inleting water hole, the inclined hole plug screw is tightened against in the spool water outlet sector hole, and is solid with glue spots, makes inclined hole toward inclined to one side 60 ° of water (flow) direction.
At ordinary times fire-fighting water inlet is to the thrust of core assembly, and the acting in conjunction that adds upper spring makes core assembly prop up sealing conical surface of valve body, realizes closing sealing.During unlatching, the water source is caused actuator chamber, core assembly is moved toward inlet side, make sealing ring leave sealing cone, open water outlet; When closing, venting actuator chamber hydraulic pressure, core assembly move to sealing surface and to close sealing under the common promotion of source pressure and spring.When pressure of supply water fluctuation or when cutting off the water supply because the impetus of spring force, intake pressure, add that the inclined hole plug screw gets rid of the remaining water of actuator chamber in real time, guarantee that valve remains on sealing state, stopped to open by mistake notice so.The valve inleting water hole cooperates with inclined hole plug screw relief hole, reaches the slow supercharging of actuator chamber, pressure release, makes that spool slow is opened, Slow Close, has eliminated water hammer effect.
The novel beneficial effect of the present invention is: adopt pressurised driving to open, Seal Design is closed in following current, utilize water inlet thrust and the acting in conjunction of spring that spool is closed, the inclined hole spiro pluging hole be set get rid of in real time water more than the actuator chamber, guarantee water pressure fluctuations or when cutting off the water supply valve close performance; The valve inleting water hole cooperates with inclined hole plug screw relief hole, makes that spool slow is opened, Slow Close, has eliminated water hammer effect; Spool adopts the design of following current guide flow, and the conducting area is large, and the flow resistance loss only is 0.02MPa; Valve body with advance/water out adapter adopts low carbon stainless steel forge hot bar Precision Machining, dense materials has been guaranteed the water pressure test for strength requirement of this valve 24MPa.
