Description
Technical field
The utility model relate to a kind of carry seal ring and lock revolve cone valve mandrel.
Background technique
The existing cone valve Sealing that revolves is arranged on valve seat more, no matter soft and hard seal, and production and processing is all difficult, and after Long-Time Service Sealing damages, and maintenance must dismounting be whole revolves cone valve or changes valve seat, and regular maintenance is easy not, and manufacturing efficiency is difficult to improve.
Summary of the invention
The purpose of this utility model be to provide a kind of carry seal ring and lock revolve cone valve mandrel, it is compact, easy to process that this revolves poppet valve core axle construction, and the dismounting being conducive to complete valve is safeguarded.
The technical solution of the utility model is: a kind of carry seal ring and lock revolve cone valve mandrel, comprise valve core shaft, the bottom of described valve core shaft is connected with circular cone, the external wall of upper portion of described circular cone has the seal ring preventing complete valve flowing medium from leaking, the sidewall of circular cone offers the through hole be connected with the cavity of circular cone inside, the sidewall of circular cone is positioned at through hole side and is also provided with sealing lock for complete valve opening and closing, the lower sides of circular cone is also arranged at intervals with at least two projections.
Further, described valve core shaft and circular cone are a rigidity one integral piece, described seal ring, sealing lock and projection protrudes from the outer wall of circular cone and its outer side wall is the conical surface.
Further, the outer side wall of described seal ring, sealing lock and projection is positioned on the same conical surface.
Further, the top of described valve core shaft is provided with screw thread, and the top of described sealing lock is connected with seal ring, both and projection and circular cone one-body molded.
Further, described valve core shaft and circular cone are made up of rigid material, and described seal ring, sealing lock and projection and the valve seat revolving cone valve form hard sealing.
Further, described valve core shaft and circular cone are made up of rigid material, circular cone can be arranged for forming soft seal with the valve seat revolving cone valve and with seal ring, the plastic sleeve sealing lock and projection.
Compared with prior art, the utility model has the following advantages: not only compact structure, easy to process, and the dismounting being conducive to complete valve is safeguarded; Its complete valve has selfsealings, wear-self-compensation function, and without dead angle, good sealing effect; Seal ring, sealing lock and projection size can adjust when manufacturing and designing according to specific pressure when using, and therefore the utility model will cause enterprise to process maintenance cost reduction, and manufacturing efficiency and benefit improve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circular cone male cone (strobilus masculinus) unfolded drawing of the present utility model;
In figure: 10-valve core shaft 20-circular cone 21-seal ring 22-cavity 23-through hole 24-seals lock 25-projection.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
With reference to figure 1 and Fig. 2
A kind of carry seal ring and lock revolve cone valve mandrel, comprise carry seal ring and lock revolve cone valve mandrel 10, the bottom of described valve core shaft is connected with circular cone 20, the top of described circular cone has its outer wall outstanding, seal ring 21 in order to prevent complete valve flowing medium from leaking, itself and valve seat fit in sleeving valve behind the door, no matter valve opening or close and can effectively prevent leaking of flowing medium.The sidewall of circular cone offers the through hole 23 be connected with circular cone internal cavity 22, so that the flowing medium entered in cavity is flowed out by through hole.The sidewall of circular cone being positioned at through hole side is also provided with for being embodied as the sealing lock 24 overlapping valve opening and closing, and described sealing lock shutoff valve seat water outlet after mandrel rotates forms interior sealing, makes complete valve be in effective off state; Described sealing lock to stagger valve seat water outlet after mandrel rotates, and circular cone lateral through aperture communicates with valve seat water outlet, and complete valve is in opening state.The lower sides of circular cone is also arranged at intervals with at least two projections 25, and one of them projection is arranged at the downside of through hole and is connected with through hole, and projection is supported on the sidewall of valve seat, whole mandrel is not turned and partially rocks.
In the present embodiment, described valve core shaft and circular cone are a rigidity one integral piece, and described seal ring and sealing lock protrude from the outer wall of circular cone, and its outer side wall is the conical surface, to coordinate with valve base sealing.
In the present embodiment, described seal ring, sealing lock and the outer side wall of projection are positioned on the same conical surface, and its tapering is equal with complete valve seat tapering, seal ring, sealing seat and valve seat are adjacent to seal and realize auto-compensation after revolving cone valve mandrel wear.
In the present embodiment, described valve core shaft is provided with screw section, is fixed by nut check so that valve core shaft passes valve seat; The top of described sealing lock be connected with seal ring and with projection and circular cone one-body molded, to improve mechanical strength, reduce difficulty of processing.
In the present embodiment, described valve core shaft and circular cone are made up of rigid material, and described seal ring, sealing lock and valve seat form hard sealing.
In the present embodiment, described valve core shaft and circular cone are made up of rigid material, circular cone can be arranged the plastic sleeve of band seal ring, sealing lock and projection, to form soft seal with the valve seat revolving cone valve.
In the present embodiment, can also the abrasion-proof corrosion-proof corrosion material such as ceramic coated on the cavity of circular cone and outer wall, tetrafluoro, be applied to the fields such as strong acid and strong base; Food service industry is specially adapted to without dead angle when complete valve uses simultaneously.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
