In the conventional paddle type alarm valve, the circular clapper is closed by the hydraulic balance of the primary and secondary sides, but when a fire occurs, the circular clipper is opened by the hydraulic pressure difference, and the flow resistance acting on the plastic paddle installed in the flow path of the ball is applied. The alarm works by sending it to the alarm switch, but the flow resistance by the plastic paddle installed in the ball's flow path increases a lot, the plastic paddle's durability decreases, and the flow resistance varies depending on the flow rate. Reliability decreases.

In addition, since the alarm valve and the ball valve are integrally formed, the contact surface pressure between the ball and the Teflon seat ring is greatly increased because the screws formed on the seat ring are tightly tightened to secure the sealing force of the ball valve, and at the same time, the operating force of the handle is increased. Since the damage of Teflon seating occurs and the durability is poor, the problem of leaking water has been raised.

In addition, although the seat ring is screwed to the inner diameter of the body of the ball valve, the circular clapper is assembled with pins on the protrusions of the metal round cover, so that the loosening problem caused by the different fixing bodies and sealing problems caused by this are sufficient. The surplus assembly tolerance, which should be considered, acts as a cause of deteriorating the sealing property between the seat ring and the circular clapper.

In addition, since the metal circular cover is fastened to the circular flange, it requires a lot of installation space, it is difficult to reduce the weight, and it is difficult to check whether there is a malfunction related to accumulation, failure or damage of contaminants, and the metal circular cover must be opened. Since the space for connecting the pressure gauges of the primary side and the secondary side to the flow port of the body must be separately secured, the problem of light weight and small size was raised.

In addition, if the alarm valve and the ball valve are separated from each other and the flanged alarm valve or the integrally formed paddle type alarm valve does not maintain reliable heat retention, the firefighters staying in the flow path of the ball valve through which the flowing water passes are in winter. There was a problem that freeze occurs while freezing.

In addition, it is difficult to prevent leakage of high-pressure firefighters with the O-ring installed on the stem portion or seat ring of the ball valve, and since the tightening force of the handle is increased to increase the sealing of the Teflon seating of the ball valve, the handle force of the handle must be increased to increase the ball valve There was a high possibility of failure in the driving part.

Therefore, the conventional paddle-type alarm valve has a large operating force to operate the ball valve, malfunction and low durability due to incorrect deformation behavior of the plastic paddle, and a large clearance between the seating and the circular clapper, inaccurate sealing property, and metal round shape. Due to the large installation space due to the use of the cover and the inability to check the inside, and the increase in flow loss caused by the asymmetry of the connection between the alarm valve and the ball valve, the overall height of the paddle type alarm valve and the diameter of the valve increase, making it difficult to reduce weight and size and maintain A problem was raised that maintenance was not easy.

Accordingly, the present invention was devised to solve the above-mentioned problems as described above, and the purpose thereof is a general malfunction problem of the alarm switch due to shock pressure caused by leakage of the secondary sprinkler system or sudden operation of the filling pump, In addition, in case of paddle type alarm valve, malfunction of alarm alarm due to inaccurate signal data, which varies depending on the sensitivity of deformation behavior of plastic paddle, and when the alarm valve and ball valve are installed separately, contaminants can cause In order to solve the malfunction problem that the alarm switch does not operate normally by being caught in the operation part, the optimal design of the alarm composite valve system and the mechanism and method of securing the alarm signal data are modified to solve the overall malfunction problem of the alarm composite valve. .

In addition, due to assembly play and sealing problems caused by assembling and opening and closing the circular clapper and seating ring on different bodies, the signal data and durability of incorrect deformation behavior of the plastic paddles, and the plastic paddles installed in the flow path of the ball Increased flow loss, an alarm valve and a ball valve are integrally formed, while stress concentration due to the difference in the curvature of the connection part and the problem of having to grow the body by installing a large-diameter circular flange, and high pressure due to the general O-ring used to prevent leakage And the problem of high sealing, the problem of the Teflon seating being damaged due to the increase in the operating force of the handle because the seating is too tight to secure the sealing of the ball valve, and the metal circular cover even if a malfunction occurs due to contaminants in the drive connection For maintenance difficulties that can be confirmed only by removing, the problem that the valve stays frozen due to freezing of water in the ball valve flow path is installed by installing a double clapper system equipped with an angle sensor, and sealing and semi-tool seating with improved lubricity. A semi-tool valve system equipped with a double O-ring is integrally molded into the alarm valve structure, a pressure gauge is integrally formed on the flange, and a strainer is installed to prevent malfunction due to foreign matter inflow and contamination without opening the metal round cover. By installing a trapezoidal transparent cover that can check substances, it prevents malfunction of the alarm composite valve, reduces flow resistance, reduces weight and size, shortens the assembly process, prevents freezing of semi-tool valves, prevents leaks and increases water pressure, checks and repairs faults easily. It is to provide an alarm composite valve capable of lighting.

In order to achieve the object of the present invention, a strainer for blocking the inflow of contaminants is installed on the lower surface of the seat ring for a semi-tool, and a plurality of circular protrusions are installed on the upper surface of the seating to secure the sealing property. On the side, a groove for a double O-ring and a male screw are installed to fasten the female screw formed on the body to secure the sealing and fastening force. Formed, the upper surface of the circular clapper is equipped with a small shape auxiliary circular clapper that can absorb the increase in the shock pressure caused by the pump, and an angle sensor connected to the alarm switch, respectively, so that the alarm sounds quickly without malfunction of the alarm due to the opening of the double clapper It is characterized by being made.

In addition, it is equipped with a transparent cover to check whether there is a blockage or malfunction due to the inflow of contaminants, leakage due to accumulation of foreign substances in the seal, or a malfunction. Prevent, reduce overall height to achieve light weight, reduce the inner diameter and total height of the alarm valve as much as possible with the optimal design, and form a pressure gauge integrally with the flange to further reduce the height and weight to shorten the assembly time and reduce plasticity. It is characterized by achieving the operational stability and reliability of the alarm composite valve, light weight, small size, high pressure, and easy maintenance by reducing the flow resistance by removing the paddle and blocking leakage even at high water pressure by adopting a double O-ring.
