Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, in an embodiment of the present invention, a wet alarm valve for fire fighting includes a valve body 1, a plurality of valve seats 2 are fixedly installed inside the valve body 1, a positioning column 13 is disposed on one side inside the valve body 1, a push rod 18 is slidably installed on the positioning column 13 through a sliding hole formed thereon, a valve clack 4 corresponding to the position and the quantity of the valve seat 2 is fixedly sleeved on the outer wall of the push rod 18, and a second spring 11 is sleeved between the valve clack 4 and the positioning column 13 on the outer wall of the push rod 18.

Referring to fig. 1 and fig. 3, in this application, one side on the outer wall of valve body 1 is provided with arc apron 10, fixed slot 17 with reference column 13 looks adaptation is seted up to arc apron 10's internal surface, and reference column 13 and fixed slot 17 joint, standing groove 14 has been seted up on arc apron 10's the surface, through-hole 16 has been seted up to the bottom of standing groove 14 inner wall, sliding connection has bolt 15 on through-hole 16, thread groove 12 has been seted up on reference column 13's top, and thread groove 12 and bolt 15 threaded connection, be provided with stop gear on valve body 1's the outer wall.

Referring to fig. 1, in the present application, the limiting mechanism includes an annular fixing member 6, and the annular fixing member 6 is fixedly sleeved on the outer wall of the valve body 1, the annular fixing member 6 has a limiting rod 8 through a sliding hole slidable mounting provided thereon, one end of the limiting rod 8 is fixedly mounted with an annular limiting member 9, and the annular limiting member 9 is slidably sleeved on the outer wall of the valve body 1, the other end of the limiting rod 8 is fixedly mounted with a stopper 5, and a first spring 7 is sleeved between the annular fixing member 6 and the annular limiting member 9 on the outer wall of the limiting rod 8.

Referring to fig. 1, in the present application, symmetrically distributed sliding rods 3 are fixedly installed on one side of a valve flap 4, and the sliding rods 3 are slidably connected with sliding holes formed in corresponding positions on a valve seat 2.

Referring to fig. 3, in the present application, a sealing gasket is disposed at a joint of the arc-shaped cover plate 10 and the valve body 1.

Referring to fig. 3, in the present application, a sealing gasket is disposed at a connection portion between the positioning column 13 and the fixing groove 17.

The utility model discloses a theory of operation is:

referring to fig. 1 to 3, when in use, two ends of a valve body 1 are respectively connected with a system pipe network port and a water supply pipe network port into a whole by flanges, when in operation, the pressure of the water supply pipe network port is greater than that of the system pipe network port, so that water flow upwards extrudes the rightmost valve flap 4, the valve flap 4 positioned at the rightmost side is the position with the largest impact force of water at ordinary times, the valve flap 4 is extruded to drive the valve flap 4 to drive the ejector rod 18 to move towards the left side together, the ejector rod 18 moves to slide on the positioning column 13, meanwhile, the ejector rod 18 moves to extrude the second spring 11 through the leftmost valve flap 4, the valve flap 4 drives the sliding rod 3 to slide on the valve seat 2 in the moving process, and thus the stability of the valve flap 4 during moving can be ensured, A plurality of valve clacks 4 on this alarm valve can synchronous motion, lose behind the sealing effect to disk seat 2 at valve clack 4, water can flow through a plurality of disk seats 2, and flow into to the system pipe network in from the one end of valve body 1, pressure when the water supply network port is less than the pressure of system pipe network port, under the elastic action of second spring 11, can drive valve clack 4 and reset, realize closing of alarm valve, in the use, through a plurality of valve clacks 4's setting in the alarm valve, in time under the serious condition of rightmost side valve clack 4 wearing and tearing, it also can take over the rightmost side valve clack 4 and continue to work to be located left valve clack 4, guarantee the sealed effect of valve body 1, can not be because of the damage of a valve clack 4, directly lead to the whole leakage of valve body 1, guarantee the holistic stability of valve body 1.

Referring to fig. 1 and 3, in use, during frequent opening and closing of the valve body 1, the second spring 11 is continuously elastically deformed, the second spring 11 has a certain service life, and needs to be replaced by fixing, when the second spring 11 needs to be replaced, the annular limiting member 9 can be directly driven to slide to the right side on the outer wall of the valve body 1, the movement of the annular limiting member 9 drives the limiting rod 8 to slide on the annular fixing member 6, and the movement of the annular limiting member 9 can extrude the first spring 7, when the annular limiting member 9 is completely separated from the outer surface of the arc-shaped cover plate 10, the arc-shaped cover plate 10 loses the limiting effect of the annular limiting member 9, then the bolt 15 is directly screwed by a tool, and the bolt 15 is quickly screwed out from the inside of the thread groove 12 by the thread transmission effect of the bolt 15 and the thread groove 12, when the bolts 15 are not completely screwed out from the inside of the thread groove 12, at this time, the arc-shaped cover plate 10 is lifted upwards by a certain distance through the sliding relationship between the through holes 16 and the bolts 15, so that the arc-shaped cover plate 10 loses contact with the valve body 1, then the arc-shaped cover plate 10 integrally moves towards the left side, the movement of the arc-shaped cover plate 10 drives the positioning columns 13 to move together, the positioning columns 13 are directly separated from the left end of the ejector rods 18 through the sliding relationship between the positioning columns 13 and the ejector rods 18, then the arc-shaped cover plate 10 and the positioning columns 13 are communicated to be dismounted together, after the arc-shaped cover plate 10 is dismounted, an operation hole is presented on the outer wall of the valve body 1, through the operation hole, the second spring 11 on the outer wall of the ejector rods 18 can be directly dismounted for replacement, and after replacement, otherwise, the arc-shaped cover plate 10 and the positioning columns 13 can be newly mounted by operation, then lead to limit structure, carry on spacingly to arc apron 10 once more, consequently this valve body 1 only needs to dismantle local structure when changing second spring 11, alright realize the change to second spring 11, unusual convenience, the practicality is high.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
