Abstract
The utility model discloses a kind of ball valve, comprise valve body, spheroid, valve rod and a head part, spheroid is positioned at valve body, and the top of spheroid is connected with valve rod, and a head part is located at bottom spheroid.That props up head part arranges the force bearing point increasing spheroid, and stress balance when impelling spheroid to rotate, prevents spheroid and valve rod joint from loosening, and increases the working life of ball valve.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ball valve.
Background technique
The valve stem end of existing Float ball valve inserts in the groove at spheroid top, and drive spheroid to rotate by valve rod, and spheroid receives the pressure of liquid, stronger active force is also born in the cooperation place of valve rod and spheroid.When ball valve access times increase, the cooperation place of valve rod and spheroid top groove loosens, and impels spheroid to be shifted, and water leakage phenomenon occurs.Inevitably there is the impurity such as sand grains in tap water, sand grains accumulates in ball valve, weares and teares, and is subject to larger resistance, cause Seepage to occur when spheroid rotates under valve rod drives.
Model utility content
The purpose of this utility model is to provide a kind of ball valve avoiding occurring Seepage, long service life.
For achieving the above object, according to an aspect of the present utility model, provide a kind of ball valve, comprise valve body, spheroid, valve rod and a head part, spheroid is positioned at valve body, and the top of spheroid is connected with valve rod, and a head part is located at bottom spheroid.Thus, the force bearing point arranging increase spheroid of a head part, stress balance when impelling spheroid to rotate, prevents spheroid and valve rod joint from loosening, and increases the working life of ball valve.
In some embodiments, valve body is provided with the first groove, and the bottom of spheroid is provided with second groove corresponding with the first groove location, and a head part is positioned at the first groove and the second groove.Thus, the setting of the first groove and the second groove is convenient to install a head part, and structure simple, be easy to processing.
In some embodiments, propping up head part is flexible glue block or ball.Thus, flexible glue block and ball can both realize the effect of support.
In some embodiments, ball valve also comprises valve gap, and one end of valve body is liquid feeding end, and the other end is outlet end, and valve gap is located at the liquid feeding end of valve body, and valve gap and valve body part are provided with filter member.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 valve body 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 force bearing point arranging increase spheroid of a head part of this ball valve, and stress balance when impelling spheroid to rotate, prevents spheroid and valve rod joint from loosening, and increases the working life of ball valve.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.Ball valve of the present utility model has leakage proof, long service life, durable, structure simple, be easy to the advantage of production and processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ball valve of the utility model one mode of execution;
Fig. 2 is the structural representation of the valve body of ball valve shown in Fig. 1;
Fig. 3 is the structural representation of the spheroid of ball valve shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 ~ 3 show schematically show the ball valve according to a kind of mode of execution of the present utility model.
As shown in Figure 1, the ball valve of present embodiment comprises valve body 1, spheroid 2, valve rod 3, head part 4 and valve gap 5.Spheroid 2 is positioned at valve body 1.The top of spheroid 2 is connected with valve rod 3.Prop up head part 4 to be located at bottom spheroid 2.One end of valve body 1 is liquid feeding end, and the other end is outlet end, and valve gap 5 is located at the liquid feeding end of valve body 1.Be provided with filter member 6 between valve gap 5 and valve body part 1, the filter member 6 of the present embodiment is filter screen, and filter member 6 can also be filter felt in actual applications.The edge of filter member 6 is provided with seal ring 61.
As shown in Figures 2 and 3, valve body 1 offers the first groove 11, and the bottom of spheroid 2 offers second groove 21 corresponding with the first groove 11 position, and a head part 4 is positioned at the first groove 11 and the second groove 21.Propping up head part 4 is flexible glue block or ball, and in the present embodiment, a head part 4 is stainless steel ball.
As depicted in figs. 1 and 2, valve body 1 comprises main valve body 12, feed liquor valve seat 13 and fluid valve seat 14.Feed liquor valve seat 13 and fluid valve seat 14 are located at the two ends of main valve body 12, and are fixedly connected with main valve body 12.Feed liquor valve seat 13 and fluid valve seat 14 all have axial passage, and the axial passage of two is positioned at same straight line, form the fluid passage of valve body 1.Spheroid 2 is positioned at main valve body 12.Feed liquor valve seat 13 and fluid valve seat 14 are all provided with O-ring seal 15, and O-ring seal 15 offsets with the outer surface of spheroid 2, realizes sealing effect.
Feed liquor valve seat 13 and valve gap 5 are for being threaded, and top filter member 6 and the seal ring 61 of valve gap 5 are pressed on feed liquor valve seat 13.Valve gap 5 also has the axial passage with feed liquor valve seat 13 conducting.Therefore, when liquid enters valve body 1 by valve gap 5, filter member 6 can solid impurity in filtering liquid.
As shown in figures 1 and 3, spheroid 2 has square groove 22, and one end of valve rod 3 is inserted in square groove 22 through after the outer wall of main valve body 12.The other end of valve rod 3 is provided with handle 7.
When needs open or close ball valve, be with ovable valve stem 3 by handle 7, and then spinning ball 2, make the channel conductive of the passage of spheroid 2 and valve seat 1 or block the passage of valve seat 1.When spheroid 2 rotates, a head part 4 provides force bearing point, and the stressed of spheroid is balanced more.
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.
