Abstract
The invention relates to an integral pre-acting alarm valve, which is used for controlling in an automatic or mannual way, designed to be in a reduced pressure driving cover plate type direct circulation structure, has water supply flow rate being 4500L/min and belongs to the fields of firefighting and water supply and drainage. The integral pre-acting alarm valve consists of a valve body, a bonnet, an end cover, a valve plate shaft, a pressing fastener shaft, a main sealing ring, a valve plate, a pressing plate, a valve seat, a pressing fastener, an ejector rod, a piston, a control diaphragm, a torsion spring and an orifice plate connector. The main sealing ring is fixedly clamped on the valve plate by the pressing plate. The valve plate covers the valve seat and is locked by the middle wedge opening of the pressing fastener. The high end of the pressing fastener is propped up by the ejector rod. The acting force of the ejector rod comes from the control diaphragm and the piston. A ring hole is arranged in the valve seat and is communicated with a valve body alarm opening. A conventional pre-acting alarm valve is formed by serially connecting a deluge alarm valve with a one-way valve, and an alarm opening is arranged on a pipe between the deluge alarm valve and the one-way valve. By innovatively designing the valve seat and optimizing the deluge alarm valve and the one-way valve into one valve, i.e. the integral pre-acting alarm valve, compared with the existing products, the height is decreased by 565mm, the piping is simple, the operation and the maintenance are facilitated, the hydraulic friction loss is decreased by 0.09MPa and the weight is decreased by 40kg. The integral pre-acting alarm valve has a wide application prospect in ships, naval vessels, files, libraries, power, banks and warehouse logistics.
Description
Technical field
The present invention is novel to be related to a kind ofly for fire protection sector, and rated working pressure is 1.6MPa, and nominal diameter is DN150mm, water supply flow reaches 4500L/min, be designed to standard-sized sheet direct current water flowing force mode, adopt valve plate button type sealing configuration, opening ways drives for decompression.The core control valve in the preact automatic fire extinguishing system----integral type preact alarm valve belongs to fire-fighting, plumbing field.
Background technique
Existing preact alarm valve device is comprised of deluge alarm valve, one-way valve, fire-fighting Signal butterfly bamper and flange connecting pipe, highly is 950mm, and the flow resistance loss reaches 0.11MPa, and weight is 115Kg; Dispose supply air line, warning pipeline, water pipe, water injecting pipeline, pilot line and test pipeline.The valve body material: HT200 cast iron, intensity is lower; Rated working pressure is on the low side, is 1.2MPa.
Present preact alarm valve device, its warning pipeline are arranged at by on the pipeline section between deluge alarm valve, the one-way valve; Utilize one-way valve as the trapping sealed member, the one-way valve trapping sealability of DN150 is unreliable, causes frequent, the lasting startup of air compressor to move; Present preact alarm valve device accessory is numerous and diverse, and the flow resistance loss reaches 0.11MPa; Maintaining, the operation loaded down with trivial details; Current preact alarm valve device boundary dimension is too huge, transportation, the installation of marching into the arena are brought inconvenience, can not satisfy the short application places such as boats and ships naval vessels, pump house equipment room, valuable secret storehouse, conventional preact alarm valve device has been unsuitable for new industry escort, do not satisfied the user of each side to the demand of fire product Continual Improvement.
Summary of the invention
In order to fill up the blank of domestic integral type preact alarm valve, deluge alarm valve and one-way valve designs are modified into a preact alarm valve, the flow resistance loss is reduced in below the 0.02MPa, water output 〉=4500L/min, and the valve body height is reduced to 385mm, the present invention is novel to provide a kind of integral type preact alarm valve, its rated working pressure is 1.6MPa, and nominal diameter 150mm, minimum breakout pressure are 0.14MPa, loss of head≤0.02MPa, opening time＜5s; New design of the present invention has adopted the valve seat construction of Multifunction: have sealing plane, warning runner and locking structure, the conducting area is large, compact structure; Designed the primary seal circle of tool lip compensation sealing effect, the water tightness that also remains intact during in the occasion of frequent vibration, in water pressure fluctuations; Be provided with the compression button of lever force-saving mechanism, compress button and carve upward 5 ° of mouth with valve plate snap close surface of contact, intersection is led the R1 fillet, and starting-up response is sensitive; When closing snap close, play the effect that progressively compresses, prolonged the working life of product.The present invention is novel to be with a wide range of applications in single chain preaction system, doubly-linked lock preaction system.
The novel integral type preact alarm valve that is achieved in that of the present invention is by spheroidal graphite cast iron valve body, valve gap, end cap, stainless steel valve seat, pressing plate, torsion spring, valve shaft, the primary seal circle that compresses button, compression buckle shaft, tool lip collocation structure, lock plunger and orifice plate composition; Valve seat is fixed in the valve body with lock plunger, and the primary seal circle is clamped on the valve plate with pressing plate, and valve plate is carved a mouthful inclined-plane compression maintenance sealing by compressing button at ordinary times, compresses button and is withstood in vertical direction by piston, push rod and compression button.
The current of fire water source enter in the end cap by water pipe at ordinary times, and Water Pressure is to the control diaphragm, and pushing piston, push rod prop up and compress button, and lock is pushed down valve plate, makes the valve closing sealing.During unlatching, by the hydraulic pressure in the electric/manual venting end cap, valve plate overturns under the intake pressure effect, opens to the system pipe network water-filling; A part of water enters the warning pipeline simultaneously, makes pressure switch, warning water system action.Close when resetting, close into the water Signal butterfly bamper, hydraulic pressure in the venting end cap, rotate counterclockwise and compress 90 ° on button, valve plate is fallen on the valve seat, open water pipe and make fire water supply enter end cap, Water Pressure is in the control diaphragm, pushing piston, push rod prop up and compress button, and lock is pushed down valve plate, make valve keep closing sealing.
The novel beneficial effect of the present invention is: deluge alarm valve and one-way valve are united two into one, device height is reduced to 385mm from former 950mm, the flow resistance loss is reduced to below the 0.02MPa from former 0.11MPa, and weight is reduced to 75Kg from former 115Kg, and transporting, march into the arena, it is convenient to install; Pipeline is simpler, and operation, repair and maintenance are conveniently; Adopt the spheroidal graphite cast iron valve body, rated working pressure is increased to 1.6MPa from present 1.2MPa; Be particularly suitable for the short application places such as boats and ships naval vessels, pump house equipment room, valuable secret storehouse; The valve seat construction of Multifunction has been adopted in design: have sealing plane, warning runner and locking structure; Designed the primary seal circle of tool lip compensation sealing effect, the water tightness and the tightness that also remain intact during in the occasion of frequent vibration, in water pressure fluctuations, the pressure of water source side is born by the stainless steel valve plate, has prolonged the life-span of primary seal circle; Stopped the not good situation of current heavy caliber one-way valve air-tightness.
