Referring to fig. 3, in the present application, the inner diameter of the through hole 18 is larger than the outer diameter of the operating rod 19.

The utility model discloses a theory of operation is:

referring to fig. 1 to 3, when the fire hydrant is used, the hand wheel 5 is rotated, the valve rod 12 is driven to rotate by the rotation of the hand wheel 5, the valve rod 12 is driven to vertically move by the screw transmission between the valve rod 12 and the screw sleeve 6, the valve rod 12 moves through the rotation relation with the first valve clack 10, and the second valve clack 11 moves through the sliding relation between the limiting block 8 and the limiting through groove 7, so that the first valve clack 10 and the second valve clack 11 vertically move along with the valve rod 12 but cannot rotate along with the valve rod 12, when the first valve clack 10 and the second valve clack 11 move upwards, the limiting block 8 is driven to move by the movement of the limiting block 8, the connecting frame 9 drives the sleeve 17 to move, the sleeve 17 drives the mounting rod 22 and the sealing block 14 to move upwards by the cooperation of the spring 21, so as to directly fit the sealing block 14 with the drain hole 13, meanwhile, the fire hydrant is opened by the upward movement of the first valve flap 10, water enters the water outlet end 3 from the water inlet end 2 and flows out, the second valve flap 11 continuously moves upward along with the continuous opening of the fire hydrant, the sleeve 17 is driven to continuously move upward through the connecting frame 9, the sealing block 14 enters the inside of the water outlet hole 13 along with the initial opening of the fire hydrant, the sealing block 14 stops moving upward under the blocking of the water outlet hole 13, the sleeve 17 still slides upward on the outer wall of the mounting rod 22, the spring 21 is squeezed in the sliding process, the elastic deformation of the spring 21 applies force to the mounting rod 22, the sealing block 14 is more tightly fitted in the inside of the water outlet hole 13 through the mounting rod 22, and therefore, as the water flow of the fire hydrant is larger and larger, the sealing block 14 and the water outlet hole 13 are more tightly fitted under the elastic action of the spring 21, the sealing degree of the fire hydrant body 1 is ensured under the condition of large water pressure, the phenomenon of water leakage through the drain hole 13 is avoided, the fire hydrant is closed in the later stage, the first valve clack 10 and the second valve clack 11 are reset, the water inlet end 2 stops water inlet, the sleeve 17 can also reset along with the connecting frame 9, the elastic effect of the spring 21 is smaller and smaller, the sealing block 14 can be driven to slightly break away from a certain distance in the drain hole 13, the sealing block 14 cannot completely seal the drain hole 13 at the moment, residual water inside the fire hydrant body 1 can be generated due to the position of the drain hole 13, the water can directly flow out of the fire hydrant body 1 through the drain hole 13, the problem that the fire hydrant is rusted due to corrosion of the inside of the fire hydrant after the fire hydrant is used is solved, the service life of the fire hydrant is prolonged, meanwhile, the drainage structure of the fire hydrant is closed according to the opening of the fire hydrant, the fire hydrant is opened and is linked with high practicability.

Referring to fig. 1 and 3, in use, the sealing block 14 is inevitably worn during daily use, so as to ensure the sealing effect of the sealing block 14 on the drain hole 13, the sealing block 14 needs to be replaced after reaching a certain wear degree, when the sealing block 14 needs to be replaced, the knob 20 is rotated, the rotation of the knob 20 drives the operating rod 19 to rotate, the rotation of the operating rod 19 drives the second bevel gear 33 to rotate, the first bevel gear 32 rotates through the engagement of the second bevel gear 33 and the first bevel gear 32, the rotation of the first bevel gear 32 drives the adjusting screw rod 31 to rotate, the positioning rod 28 is separated from the inside of the positioning groove 27 through the screw transmission of the left-handed thread and the right-handed thread on the adjusting screw rod 31, and the movable block 30 moves relatively or oppositely through the sliding relationship between the positioning block 25 and the transverse groove 24, the movable block 30 moves to drive the positioning rod 28, when the two movable blocks 30 move relatively, the positioning rod 28 is separated from the inside of the positioning groove 27, the sealing block 14 loses the effect with the mounting box 26, the effect of the sealing block 14 is changed, the sealing block 14 can be conveniently and the sealing block 14 can be mounted on the sealing block 14, and the sealing block can be mounted on the sealing block.

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.
