Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples, which are not intended to limit the present invention.

As shown in fig. 1, the embodiment of the utility model discloses a valve gap 2 including disk seat 1 and setting on disk seat 1, valve gap 2's below is provided with feed inlet 3, still include seal structure, seal structure includes first seal structure and second seal structure, first seal structure includes first recess 4 and sets up the first sealing washer in first recess 4, second seal structure includes second recess 5 and sets up the second sealing washer in second recess 5, through first sealing washer and second sealing washer sealing connection between valve gap 2 and the valve body 1. The first groove 4 comprises a first upper groove 6 and a first lower groove 7, the first upper groove 6 is arranged at the lower end of the valve cover 2, the first lower groove 7 is arranged at the upper end of the valve body 1, and the first sealing ring is arranged in the first upper groove 6 and the first lower groove 7 in a sealing mode. The second groove 5 comprises a second upper groove 8 and a second lower groove 9, the second upper groove 8 is arranged at the lower end of the valve cover 2, the second lower groove 9 is arranged at the upper end of the valve body 1, and the second sealing ring is arranged in the second upper groove 8 and the second lower groove 9 in a sealing mode. The diameter of the first sealing ring is larger than that of the second sealing ring. The width of the first groove 4 is greater than the width of the second groove 5.

In this embodiment, through having set up two sets of sealing washers for the sealed effect of connection of valve gap 1 and valve body 2 is better, and through by two-layer sealing washer within outer, can make when one of them a set of sealing washer weakens because of the sealed effect of external environment, inside sealing washer continues to keep sealed effect, great extension the life of equipment.

In this embodiment, two sets of sealing rings are arranged inside the valve body 1 and the valve cover 2, so that the contact between the sealing rings and the external environment can be reduced as much as possible, the damage of the effects of oxidation, corrosion and the like to the sealing effect is weakened, and the continuity of the sealing effect is ensured as much as possible.

In this embodiment, the width setting of outside sealing washer is greater than the width of inside sealing washer, makes the pressure upper limit that outside sealing washer bore higher like this to the too big damage that leads to of the too big and then of the pressure that the inside sealing washer bore of protection.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
