Abstract
The utility model discloses a ball valve, including disk seat, spheroid and valve rod, the spheroid is located the disk seat, and spheroidal top is connected with the valve rod, and the outside edge of disk seat tip is equipped with radial boss, and the side of boss is located the coplanar with the terminal surface of disk seat. The boss set up the sealing area who has increased the disk seat tip, can improve sealed effect, prevent leaking. Setting up of boss makes disk seat tip structure firm, improves the product percent of pass.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ball valve.
Background technique
The closure member of ball valve is a spheroid, and spheroid reaches unlatching around valve body center line do rotation, closes.Ball valve is widely used in pipeline, is mainly used to make the flow direction cutting off, distribute and change medium.Generally between valve seat and pipeline, establish Sealing when ball valve is installed, due to valve seat end wall thickness and pipeline wall thickness quite, the area of contact of both and Sealing is less, causes sealing effect not good, easily reveals.Valve seat is generally casting, and because valve seat end wall thickness is less, easily breakage occurs in process of production, up-to-standard rate is low.
Model utility content
The purpose of this utility model is good sealing effect, be easy to production and processing, ball valve that up-to-standard rate is high.
For achieving the above object, according to an aspect of the present utility model, a kind of ball valve is provided, comprise valve seat, spheroid and valve rod, spheroid is positioned at valve seat, and the top of spheroid is connected with valve rod, the outer ledge of valve seat end is provided with radial boss, and the side of boss and the end face of valve seat are positioned at same plane.Thus, the setting of boss adds the sealing area of valve seat end, can improve sealing effect, anti-leak.The setting of boss makes valve seat end construction firm, improves conforming product rate.
In some embodiments, boss and valve seat are one of the forming structure.Thus, boss and valve seat by mould once-through, easy to process, save cost.
In some embodiments, valve seat outer side surface is provided with operation unit, and operation unit is the multiple planes being positioned at the same axial height of valve seat.Thus, ball valve is in installation process, and when using setting tool to block multiple plane, valve seat rotates, and is convenient to the attended operation of valve seat and pipeline.
In some embodiments, ball valve also comprises valve gap, the first seal ring and the second seal ring, and the first seal ring and the second seal ring are divided into the both sides of spheroid and offset with spheroid, and valve gap and the first seal ring offset.Thus, the sealing realizing spheroid and valve base inner wall that arranges of seal ring is installed, and improves sealing.
In some embodiments, the first seal ring and the second seal ring are equipped with anticorrosive coat.Thus, the setting of anticorrosive coat can extend the working life of seal ring.
In some embodiments, ball valve also comprises filter member, and filter member is positioned at the liquid feeding end of valve seat, and filter member is between the first seal ring and valve gap.Thus, the solid impurity that the setting of filter member can stop in liquid enters ball valve, avoids spheroid to wear and tear, and increases ball valve working life.
In some embodiments, the edge of filter member is provided with seal ring.Thus, the setting of seal ring both can increase sealing property of ball valves, and valve gap and the first seal ring can be made again all to offset with filter member, and the sealing realizing filter member is installed.
The beneficial effects of the utility model are: the boss of valve seat end adds the sealing area of valve seat end, can improve sealing effect, anti-leak.The setting of boss makes valve seat end construction firm, improves conforming product rate.Boss and valve seat by mould once-through, easy to process, save cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ball valve of the utility model one mode of execution;
The axial sectional view that Fig. 2 is ball valve shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 ~ 2 show schematically show the ball valve according to a kind of mode of execution of the present utility model.
As depicted in figs. 1 and 2, the ball valve of present embodiment, comprises valve seat 1, spheroid 2 and valve rod 3, spheroid 2 is positioned at valve seat 1, the top of spheroid 2 is connected with valve rod 3, and the outer ledge of valve seat 1 end is provided with radial boss 4, and the side of boss 4 and the end face of valve seat 1 are positioned at same plane.The setting of boss 4 adds the sealing area of valve seat 1 end, can improve sealing effect, anti-leak.
Boss 4 and valve seat 1 are one of the forming structure.Boss 4 is one-body molded, easy to process by mould with valve seat 1, save cost.The setting of boss 4 makes valve seat end 1 stabilized structure, end not cracky when valve seat 1 is shaping, improves conforming product rate.
Valve seat 1 outer side surface is provided with operation unit 5, and operation unit 5 is for being positioned at multiple planes of the same axial height of valve seat 1.Arrange individual plane symmetry, the operation unit 5 of present embodiment has six planes and forms regular hexagon.
The inner side at valve seat 1 two ends is provided with screw thread, is convenient to valve seat 1 and pipe furnace are achieved a fixed connection, and is provided with seal ring between the two.Side and the pipeline of seal ring offset, and end face and the boss 4 of opposite side and valve seat 1 offset.Corresponding at the sheathed baffle ring of pipeline, make it corresponding with boss.
The top of spheroid 2 has square groove, and one end of valve rod 3 is inserted in square groove through after the outer wall of valve seat 1.The other end of valve rod 3 is provided with handle 31.
The ball valve of present embodiment also comprises valve gap 6, first seal ring 7 and the second seal ring 8, first seal ring 7 and the second seal ring 8 and is divided into the both sides of spheroid 2 and offsets with spheroid 2, and valve gap 4 and the first seal ring 7 offset.First seal ring 7 and the second seal ring 8 are equipped with anticorrosive coat.Anticorrosive coat is polytetrafluoroethylmaterial material.
The ball valve of present embodiment also comprises filter member 9.One end of valve seat 1 is liquid feeding end, and the other end is outlet end.Filter member 9 is positioned at the liquid feeding end of valve seat 1.Filter member 9 is between the first seal ring 7 and valve gap 6.The edge of filter member 9 is provided with seal ring.
Above-described is only mode of executions more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
