The tight fit of product is ensure that during installation, will not occur being swung between each part during use, connection
Unstable phenomenon, generally, according to for the mechanical structure that threaded connection coordinates, it is have certain gap that screw thread coordinates
, therefore during use, because of long-term switch, occur rocking between causing part, cause the sealing property in valve to be deteriorated,
And the overall service life of product can also be shortened accordingly.
The content of the invention
For the deficiency that above-mentioned prior art is present, the purpose of this utility model is to provide a kind of effective solution because of adapter
Problem causes the adapter component that valve and the sealing property variation and service life of adapter connection are shortened.
To realize above-mentioned purpose, the utility model provides following technical scheme：
A kind of adapter component, including adapter, the lateral wall of adapter are provided with external screw thread, the lateral wall of adapter at upper port
Middle part be from top to bottom sequentially provided with the second groove of the first groove and the connection of the first groove, the internal diameter of the first groove is less than the
The internal diameter of two grooves, forms step between the first groove and the second groove, platform is formed between the second groove and the lateral wall of adapter
Rank, the lower end of adapter is arranged with outer-hexagonal nut, and the upper port of outer-hexagonal nut is provided inwardly with necking, is set in the lower port of adapter
The annular position limiting convex ring of restricted necking, the lower port of adapter is provided with necking part, and sealing rubber pad is arranged with necking part.
The utility model is further arranged to：The inner chamber of the adapter is divided into epicoele and cavity of resorption, under the internal diameter of epicoele is more than
The internal diameter in chamber, forms the step of annular between upper and lower chamber.
The utility model is further arranged to：The five of the diameter with diameter greater than the second groove of first groove/
Four.
The utility model is further arranged to：The diameter of first groove and the equal diameters of necking part.
The utility model is further arranged to：5/6ths of the external diameter with diameter greater than adapter of second groove.
The utility model is further arranged to：Sealing rubber ring is provided with first groove.
The utility model is further arranged to：Back-up ring is provided with second groove, the inner ring of back-up ring end face upward is recessed
The 3rd groove of annular is provided with, the lower end of sealing rubber ring is embedded in the 3rd groove.
The utility model is further arranged to：External diameter of the maximum gauge of the 3rd groove more than sealing rubber ring.
By using above-mentioned technical proposal, the technique effect that the utility model is reached is：Preferably improve valve rod
Steadiness, while also strengthening the sealing function of valve rod, and sets cutting face, can effectively cause valve rod and handwheel or hand
The cooperation of handle etc. installs more stable, increases stationary plane and supporting surface so that the cooperation of valve rod and handwheel or handle etc. is more
Closely, eliminate counterpart between because long-term use occur shaking phenomenon so that the service life of the valve of this component is installed
Extension.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is cross section structure diagram of the present utility model.
