The technical scheme in the embodiment of the application aims to solve the problems, and the overall thought is as follows:

examples

The embodiment provides a specific structure of a ball valve with high sealing performance, as shown in fig. 1-4, the ball valve comprises a valve body 1, a valve rod 8 is arranged above the valve body 1, a handle 6 is arranged above the valve rod 8, a ball 12 is arranged inside the intersection of the valve rod 8 and the valve body 1, a sealing gasket 9 is arranged on the lower surface of the intersection of the valve body 1 and the ball 12, the sealing gasket 9 is of an annular structure, the sealing gasket 9 is concavely arranged inside the intersection of the valve body 1 and the ball 12, the sealing gaskets 9 are of annular structures, sealing strips extend from two ends of the sealing gasket 9 respectively, so that the contact surface between the sealing gasket 9 and the bottom end of the ball 12 is increased, the sealing performance of the ball valve is improved, the size of the sealing gasket 9 is larger than that of the ball 12, a circular hole is formed inside the ball 12, and the size of the circular hole is smaller than the cross-section diameter of the valve body 1.

By adopting the technical scheme:

the sealing gasket 9 is of an annular structure, the sealing gasket 9 is concaved inwards at the intersection of the valve body 1 and the ball body 12, the sealing gasket 9 is of an annular structure, and sealing strips extend from two ends of the sealing gasket 9 respectively, so that the contact surface between the sealing gasket 9 and the bottom end of the ball body 12 is increased, and the sealing performance of the ball valve is improved.

One end of valve body 1 is equipped with inlet tube 2, and the one end that inlet tube 2 was kept away from to valve body 1 is equipped with outlet pipe 3, and the inside of inlet tube 2 is equipped with filter screen 11, and the filter screen 11 is embedded to be equipped with one side that is close to valve body 1, makes filter screen 11 and inlet tube 2 attached closely like this under the fluidic effect to filter the impurity of fluid inside under filter screen 11 filters, has avoided spheroid 12 to be stained with the problem that the impurity appears blockking up, and filter screen 11 is interference connection with inlet tube 2's connected mode.

By adopting the technical scheme:

the filter screen 11 is embedded to be equipped with one side that is close to valve body 1, makes filter screen 11 and inlet tube 2 attached closely like this under the effect of fluid to filter the impurity of fluid inside under the filter of filter screen 11, avoided spheroid 12 to be stained with the impurity and appear the problem of jam.

The valve body 1 top is equipped with first stopper 4, the opposite side of valve body 1 is equipped with second stopper 5, first stopper 4 and the mutual right angle of second stopper 5, the one end of handle 6 is equipped with baffle 7, baffle 7 is located the inboard of first stopper 4 and second stopper 5, handle 6 and the crossing department of valve rod 8 are equipped with coupling nut 10, the crossing department of valve rod 8 and coupling nut 10 is equipped with connecting rod 13, rotatory handle 6, make the baffle 7 and the second stopper 5 of handle 6 bottom contact each other, when handle 6 is rotatory, drive valve rod 8 rotation, drive spheroid 12 rotation under the rotation of valve rod 8, when baffle 7 and second stopper 5 contact each other, the inside hole of spheroid 12 and the inside lateral wall of valve body 1 laminating each other, like this can not enter into outlet pipe 3 under the separation of spheroid 12, when handle 6 rotation drives baffle 7 and moves the position of first stopper 4, at this moment the water source can flow into outlet pipe 3 inside from inlet tube 2.

By adopting the technical scheme:

the handle 6 is rotated, so that the baffle 7 at the bottom end of the handle 6 is in contact with the second limiting block 5, when the handle 6 rotates, the valve rod 8 is driven to rotate, the ball 12 is driven to rotate under the rotation of the valve rod 8, when the baffle 7 is in contact with the second limiting block 5, the hole inside the ball 12 is mutually attached to the side wall of the valve body 1, and therefore a water source cannot enter the water outlet pipe 3 under the blocking of the ball 12.

Working principle: the filter screen 11 is concaved inwards in the water inlet pipe 2, and one side of the filter screen 11 is made to be close to the valve body 1, so that the filter screen 11 is attached to the valve body 1, then the water inlet connecting pipeline and the water inlet pipe 2 are connected with each other, the water outlet pipe 3 and the water outlet connecting pipe are connected with each other, thus, a water source enters from the water inlet pipe 2, and is filtered through the filter screen 11 in the interior, and the water source after filtration flows out from the water outlet pipe 3.

If do not need to carry out the flow of water source, rotatory handle 6 at this moment for baffle 7 and the second stopper 5 of handle 6 bottom contact each other, when handle 6 is rotatory, drive valve rod 8 rotatory, drive spheroid 12 rotatory under the rotation of valve rod 8, when baffle 7 and the mutual contact of second stopper 5, the inside hole of spheroid 12 is laminated each other with the lateral wall of valve body 1, the separation water source of spheroid 12 can not enter into the inside of outlet pipe 3 like this, when handle 6 is rotatory to drive baffle 7 and remove the position of first stopper 4, at this moment the water source can flow into the outlet pipe 3 inside from inlet tube 2.

The inside of inlet tube 2 is equipped with filter screen 11, and the filter screen 11 is embedded to be equipped with one side that is close to valve body 1, makes filter screen 11 and inlet tube 2 attached closely like this under the effect of fluid to filter the impurity of fluid inside under filter screen 11 filters, has avoided spheroid 12 to be stained with the problem that the impurity appears blockking up.

Finally, it should be noted that: it is apparent that the above examples are only illustrative of the present utility model and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
