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

Referring to fig. 1 to 4, the present invention provides a sealing structure of a fire valve, including a device main body 1, a top cover 2 and a protection block 3, wherein a water outlet 101 is embedded above the left and right sides of the device main body 1, a water inlet 102 is embedded in the inner bottom surface of the device main body 1, and a sealing washer 5 is nested above the outer side surface of the water inlet 102;

the embedding of top cap 2's top middle part is provided with protection piece 3, the middle part of protection piece 3 runs through and is provided with switch handle 201, switch handle 201's bottom extends to the sealed piece 4 of fixedly connected with in the device main part 1, protection piece 3's top is provided with sealed pad 301, the top fixedly connected with brush board 303 of sealed pad 301, draw-in groove 401 has been seted up to sealed piece 4's bottom, inner wall one side that device main part 1 was kept away from to draw-in groove 401 is provided with sealing ring 402, sealing ring 5's top is provided with sealing washer 502.

Further, the inner wall thickness of draw-in groove 401 is the same with the inner wall thickness of water inlet 102, when sealed piece 4 pushes down through switch handle 201 and closely laminates water inlet 102 top, water inlet 102 can block in draw-in groove 401, makes draw-in groove 401 can be sealed to the inside and outside both sides of water inlet 102 simultaneously, improves the leakproofness when sealed piece 4 and water inlet 102 close.

Furthermore, the second springs 403 are fixedly connected between the clamping groove 401 and the sealing ring 402 and are arranged in an annular shape at equal intervals, when the water inlet 102 is clamped into the clamping groove 401, the sealing ring 402 can be expanded outwards all the time through the elastic force of the second springs 403, so that the sealing ring 402 can be tightly attached to the inner wall of the water inlet 102 all the time, and the sealing performance of the sealing ring 402 on the water inlet 102 is further improved.

Further, the cross section of the sealing ring 402 is in the shape of an inverted circular truncated cone, and because the sealing ring 402 is in the shape of a circular truncated cone, a gap is formed between the lower portion of the outer side surface of the sealing ring 402 and the clamping groove 401 when the sealing ring 402 is expanded outwards through the second spring 403, so that the sealing ring 402 is not easily extruded to damage the sealing ring 402 when the water inlet 102 is clamped into the clamping groove 401.

Further, fixedly connected with is the third spring 501 that the annular equidistance was arranged between sealing washer 502 and the seal ring 5, sealing washer 502 is the rubber material, when sealed piece 4 downstream made draw-in groove 401 sealed to the inside and outside both sides parcel of water inlet 102, sealing washer 502 can expand downwards all the time through third spring 501's elasticity, the top surface that makes sealing washer 502 can closely laminate sealed piece 4 bottom, and sealing washer 502 can deform for the rubber material, make sealing washer 502 can further laminate sealed piece 4 bottom wearing and tearing position, further improve the leakproofness between sealed piece 4 and the water inlet 102.

Further, the first springs 302 arranged at equal intervals in the longitudinal direction are fixedly connected between the sealing gasket 301 and the protection block 3, and the device body 1 is installed outdoors, so that dust is easily remained on the outer side surface of the switch handle 201, the sealing gasket 301 is always attached to the outer side surface of the switch handle 201 through the elastic force of the first springs 302, external dust and impurities are made to not easily fall to the gap position between the sealing gasket 301 and the switch handle 201, and the sealing performance between the switch handle 201 and the device body 1 is improved.

Further, the brush plate 303 inclines thirty degrees from the side close to the switch handle 201 to the side far from the switch handle 201, the switch handle 201 needs to be rotated when the device is turned on or turned off, when the switch handle 201 is rotated, the brush plate 301 scrapes the residual dust and impurities on the outer side surface of the switch handle 201, and the scraped and dropped dust is easily guided outwards through the inclination angle of the brush plate 301, so that the dust and impurities are not easy to remain between the brush plate 301 and the switch handle 201.

Further, sealed pad 301 is the rubber material, and sealed pad 301 makes sealed pad 301 can deform for the rubber material, and when making sealed pad 301 pass through the elasticity of first spring 302 and paste to switch handle 201 outside all the time, sealed pad 301 can paste in the screw thread that switch handle 201 outside was equipped with, further improves sealed the leakproofness of sealed pad 301 and switch handle 201.

The working principle is as follows: when the device is used, the device main body 1 is fixed to a required position, the water inlet pipeline is connected into the water inlet 102, then, when the sealing block 4 is pressed down by the switch handle 201 to be tightly attached to the top of the water inlet 102, the water inlet 102 can be clamped into the clamping groove 401, the clamping groove 401 can simultaneously seal the inner side and the outer side of the water inlet 102, then, when the water inlet 102 is clamped into the clamping groove 401, the sealing ring 402 can always expand outwards through the elastic force of the second spring 403, the sealing ring 402 can always be tightly attached to the inner wall of the water inlet 102, subsequently, the sealing gasket 301 can always be attached to the outer side surface of the switch handle 201 through the elastic force of the first spring 302, so that external dust and impurities are not easy to fall to a gap part between the sealing gasket 301 and the switch handle 201, finally, when the switch handle 201 is rotated, the brush plate 301 can scrape dust and impurities remained on the outer side surface of the switch handle 201, and, the gasket 301 is not easily damaged to cause water leakage.

The embodiments of the present application have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art.
