Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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 5, the present invention provides a fire-fighting air valve device, which includes a device main body 1, a sealing washer 2 and a top cover 3, wherein a first interface 101 is embedded below a left side surface of the device main body 1, a second interface 102 is embedded below a right side surface of the device main body 1, the sealing washer 2 is embedded in a middle portion of one side surface of the first interface 101 and the second interface 102 away from the device main body 1, a base 103 is welded at a bottom end of the device main body 1, a clamping groove 104 is formed at a top end of the device main body 1, the top cover 3 is fixedly connected above the device main body 1 through a nut, and a handle 6 is arranged above the top cover 3;

the outer side surface of the sealing washer 2 is provided with a sealing ring 201 in an embedded mode, the middle of the top end of the top cover 3 is provided with a sealing ring 5 in an embedded mode, the bottom end of the top cover 3 is provided with a sealing snap ring 4 in an embedded mode, and the inner side and the outer side of the sealing snap ring 4 are respectively provided with sealing pieces 401 which are arranged in a longitudinally equidistant mode in an embedded mode.

Furthermore, the first springs 202 are fixedly connected between the sealing washer 2 and the sealing ring 201 and are arranged in an annular equidistant manner, and when the external pipeline is connected with the first interface 101 or the second interface 102, the sealing ring 201 can be expanded outwards all the time through the elastic force of the first springs 202, so that the sealing ring 201 can be tightly attached to the inner wall of the external pipeline all the time, and the sealing performance of the connection between the first interface 101 or the second interface 102 and the external pipeline can be improved by the sealing ring 201.

Further, the lateral surface of sealing ring 201 is from being close to one side of seal ring 2 to keeping away from one side downward sloping thirty degrees of seal ring 2, because of the outside expansion of the elasticity that sealing ring 201 can pass through first spring 202, and when external pipeline links up with first interface 101 or second interface 102, the inclination of sealing ring 201 makes external pipeline be convenient for with nested to external pipeline inner wall of sealing ring 201, improves the practicality.

Further, fixedly connected with is the second spring 501 that the annular equidistance was arranged between sealing washer 5 and the top cap 3, consequently device use in-process handle 6 need rotate opening device main part 1, lead to handle 6 can lead to the fact wearing and tearing easily with sealing washer 5, and sealing washer 5 can be laminated to handle 6 lateral surface all the time through second spring 501's elasticity, make handle 6 rotate the in-process and remove in-process sealing washer 5 and can block the adnexed impurity of handle 6 surface to top cap 3.

Furthermore, the top of the cross section of the sealing ring 5 is triangular, when the sealing ring 5 is attached to the handle 6 through the second spring 501, and the outer side surface of the sealing ring 5 is closely attached to the handle 6, impurities falling off from the outer side surface of the handle 6 can be guided outwards through the inclination angle of the sealing ring 5, so that the impurities and dust are not easy to remain between the handle 6 and the sealing ring 5, and the abrasion to the sealing ring 5 is accelerated.

Further, the transversal inverted round platform form of personally submitting of sealed snap ring 4, sealed snap ring 4 is the rubber material, top cap 3 and device main part 1 sealed back, sealed snap ring 4 can be gone into in draw-in groove 104 through top cap 3's pressure card, and the sealed snap ring 4 of round platform form makes sealed snap ring 4 card go into in the draw-in groove 104 and can be tighter and tighter, and sealed snap ring 4 has certain deformation function for the rubber material, make sealed snap ring 4 can better laminate draw-in groove 104 inner wall, make the leakproofness between top cap 3 and the device main part 1 improve.

Further, the seal fin 401 is from a side face close to the seal snap ring 4 to a side face of keeping away from the seal snap ring 4 and inclines thirty degrees upwards, when the seal snap ring 4 is clamped into the clamping groove 104 downwards through the top cover 3, the seal fin 401 can make the bottom surface of the seal fin 401 tightly fit with the inner wall of the clamping groove 104 through the extrusion pressure of the seal snap ring 4, and the top surface of the seal fin 401 can tightly fit with the seal snap ring 4, so that the firmness is improved.

Further, gasket 401 is the rubber material, and gasket 401 makes gasket 401 bear the easy deformation of pressure of sealed snap ring 4 for the rubber material for gasket 401 can closely laminate around the draw-in groove 104 inner wall, further improves the leakproofness between top cap 3 and the device main part 1.

The working principle is as follows: during the use, the user passes through the nut with external pipeline and links up with first interface 101 or second interface 102 respectively, then, sealing ring 201 can outwards expand all the time through the elasticity of first spring 202, make sealing ring 201 closely laminate external pipeline inner wall all the time, then, consequently, handle 6 need rotate opening device main part 1 in the device use, lead to handle 6 can cause wearing and tearing with sealing washer 5 easily, and sealing washer 5 can laminate to handle 6 lateral surface all the time through the elasticity of second spring 501, finally, sealed snap ring 4 can be gone into in draw-in groove 104 through the pressure card of top cap 3, and the sealed snap ring 4 of round platform form makes sealed snap ring 4 card go into in draw-in groove 104 and can be tighter and tighter, and sealed snap ring 4 has certain deformation function for the rubber material, make sealed snap ring 4 can better laminate draw-in groove 104 inner wall.

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. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
