Abstract
The utility model relates to the improvement of a sealing structure, in particular to a sealing device of a valve, and the sealing device of the valve comprises an indicator plate, wherein the surface of the indicator plate is provided with a projection, the bottom of the indicator plate is provided with a circular groove, a sealing ring is arranged inside the circular groove, the sealing ring is free from automatically dropping, the bottom of the indicator plate is provided with a clamping hook, and the indicator plate is clamped onto a worm gear through the clamping hook. Since the indicator plate is additionally provided with the sealing ring, the junction of a valve rod and a worm gear axle hole and a connection port can be sealed by utilizing the sealing ring, so that the sealing performance of the entire valve can be increased, and simultaneously the service life of the valve can be prolonged.
Description
Technical field
The utility model relates to the improvement of sealing configuration, particularly a kind of seal arrangement of valve.
Background technique
At present, the worm drive head in known various valves, in use; Because sealing is not fine between the direction board of worm gear and the worm gear, has water and oozes out, water trickles downwards; Can to valve and a worm drive connection part cause seriously get rusty stuck can not dismounting; Can cause the valve maintenance difficult, or cause some position corrosion of valve, shorten the working life of valve.
The model utility content
In order to overcome the above-mentioned deficiency that exists in the existing technology, the purpose of the utility model is to provide a kind of seal arrangement of valve, the good sealing effect of this device.
In order to reach above-mentioned purpose; The utility model adopts following concrete technological scheme: a kind of seal arrangement of valve, comprise direction board, and said direction board surface is provided with protuberance; The bottom of said direction board is provided with circular groove; Be provided with seal ring in the said circular groove, the bottom of said direction board is provided with trip, and direction board is stuck on the worm gear through trip.
Compared with prior art; The utlity model has following outstanding advantage and effect: owing on direction board, increase seal ring; After using seal ring valve rod and worm gear axis hole joint and interface are sealed increase integral valve door sealing performance, the working life of having improved valve simultaneously.
Description of drawings
Fig. 1 is the front elevation of the utility model.
Fig. 2 is the reverse side figure of the utility model.
Fig. 3 is that A-A of Fig. 1 is to explosion views.
Below in conjunction with accompanying drawing the utility model is done further to specify.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of seal arrangement of valve comprises direction board 1; Said direction board 1 surface is provided with protuberance 2, and the bottom of said direction board 1 is provided with circular groove 3, is provided with seal ring 4 in the said circular groove 3; Seal ring can not drop automatically, and the bottom of said direction board 1 is provided with trip 5, and direction board is stuck on the worm gear through trip; Owing on direction board, increase seal ring; After using seal ring valve rod and worm gear axis hole joint and interface are sealed increase integral valve door sealing performance, the working life of having improved valve simultaneously.
What should explain at last is: above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technological scheme of the utility model, and not break away from the spirit and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
