In this embodiment: by arranging the structure, when the arc-shaped position shielding plate 812 moves to the upper side of the first bolt 804, the first bolt 804 is shielded, so that the first bolt 804 is prevented from moving relative to the valve cover 2, and the stability of connection between the valve cover 2 and the diaphragm 3 and the valve body 1 is improved.
Referring to fig. 2 and 6, two guide insertion plates 828 are provided, and the two guide insertion plates 828 are symmetrically disposed along the vertical central axis of the pipe sleeve 801.
In this embodiment: by arranging this structure, when the T-shaped push rod 811 moves up relative to the pipe sleeve 801, the two arc-shaped shielding plates 812 move towards each other, so that all the first bolts 804 on the valve cover 2 are completely shielded by the arc-shaped shielding plates 812.
The following provides a use method of the deluge valve by combining the deluge valve device, which specifically comprises the following steps:
s1: when the device is used, the device is firstly installed, then water injection and pressurization are carried out between the valve cover 2 and the diaphragm 3 through the connecting pipe 6, so that the diaphragm 3 expands, the diaphragm 3 contacts with the sealing seat 806, the valve body 1 is plugged, when water injection and pressurization are carried out on a cavity between the valve cover 2 and the diaphragm 3, the diaphragm 3 is attached to the sealing seat 806, and meanwhile, the attachment degree between the sealing seat 806 and the diaphragm 3 is improved through the movement of the arc-shaped pressure guide plate 827, so that the sealing property inside the valve body 1 is improved;
s2: when a fire disaster occurs, the external detection equipment acts to link and open the electromagnetic valve of the deluge valve, and the cavity between the diaphragm 3 and the valve cover 2 is subjected to drainage and pressure relief through the pressure relief pipe 7;
s3: when the pressure in the cavity between the valve cap 2 and the diaphragm 3 is reduced, the diaphragm 3 contracts and recovers along with the reduction of the pressure, at this time, the diaphragm 3 drives the first sealing push rod 808 to move upwards, at this time, the second sealing push rod 816 moves upwards along with the first connecting flange 820, and when the second sealing push rod 816 moves upwards, the reversing straight gear 818 is shifted to rotate, so that the reversing straight gear 818 drives the shifting rack 817 to move downwards, and the plug piece 809 moves downwards along with the connecting plate 813 relative to the valve body 1, so that the sealing seat 806 is separated from the bottom of the diaphragm 3, water flow in the water inlet pipe 4 is discharged from the drain pipe 5 through the valve body 1, and the contraction direction of the diaphragm 3 is opposite to the movement direction of the sealing seat 806, so that the inner part of the valve body 1 rapidly loses the obstruction to the water flow, not only improves the opening efficiency of the valve body, but also reduces the amount of contraction required by the diaphragm 3 when the inner part of the valve body 1 is completely opened, so as to reduce the deformation of the diaphragm 3 and prevent the diaphragm 3 from being deformed greatly and affecting the service life of the diaphragm 3;
s4: when the first sealing push rod 808 moves upwards along with the shrinkage of the diaphragm 3, the second contact piece 826 is firstly contacted with the first contact piece 824, at this time, the buzzer 802 operates to generate a beeping sound, the first sealing push rod 808 continues to move upwards, at this time, the first sealing push rod 808 pushes the T-shaped push rod 811 to move upwards through the first contact piece 824, so that the reset spring 822 is shrunk, and the buzzer 802 continuously operates;
s5: when the T-shaped push rod 811 moves upwards relative to the pipe sleeve 801 under the pushing of the first sealing push rod 808, the top of the oblique connecting frame 807 is pulled by the T-shaped push rod 811, and the guide insert plate 828 moves towards the valve cover 2 under the action of the oblique connecting frame 807, so that the arc-shaped position shielding plate 812 moves to the upper part of the first bolt 804, thereby shielding the top of the first bolt 804, preventing the first bolt 804 from moving relative to the valve cover 2 due to slight vibration of the valve body 1 when water flows through the valve body 1, improving the stability of the connection between the valve cover 2 and the diaphragm 3 and the valve body 1, and improving the sealing performance of a cavity between the diaphragm 3 and the valve cover 2;
s6: the water flow sprayed out through the drain pipe 5 is subjected to fire extinguishing treatment;
s7: when the cavity between the valve cover 2 and the diaphragm 3 is filled with water and pressurized, the first sealing push rod 808 moves downwards relative to the pipe sleeve 801 along with the expansion of the diaphragm 3, at the moment, the limiting disc 823 pushes the first contact piece 824 to move downwards under the action of the reset spring 822, so that the limiting disc 823 is attached to the top of the blocking ring 825, the first contact piece 824 and the second contact piece 826 can be separated by continuing to move downwards, at the moment, the buzzer 802 stops operating, then the water injection and pressurization of the cavity between the valve cover 2 and the diaphragm 3 can be stopped, at the moment, the bottom of the diaphragm 3 can be attached to the sealing seat 806, the sealing seat 806 and the diaphragm 3 can not be completely attached when the water pressure reaches a certain value due to abrasion after the diaphragm 3 repeatedly stretches and contracts, the attachment degree of the diaphragm 3 and the sealing seat can be detected through the operation of the buzzer 802, and water leakage can be detected and alarm processed.
