Description
Technical field
The utility model belongs to technical field of valve manufacturing, refers in particular to a kind of ball valve for increasing and having filter screen.
Background technology
Ball valve can control the flow and flow direction of fluid during use, but what convection current body can be filtered
Ball valve is fewer, it will be most readily appreciated that scheme be exactly in valve body setting one layer of filter screen, can directly play the role of filtering.
But the program there are the defects of be exactly that filter screen replacement is inconvenient, over time, the impurity attached on filter screen is more, meeting
The flow of fluid is influenced, and impurity is cleared up not in time, more serious can influence the quality of fluid instead.
Invention content
The purpose of this utility model is to provide a kind of ball valve for increasing and having filter screen, and filter screen replacement is convenient.
What the purpose of this utility model was realized in：It is a kind of to increase the ball valve for having filter screen, including valve body, valve ball, valve
Bar and handle, the valve ball are arranged in valve body, and described valve rod one end connects valve ball, and the other end connects handle, wherein, the valve
The both ends of ball are both provided with sealing ring, and the port that the sealing ring is bonded with valve ball is tapered, and the trepanning on valve ball is by sealing ring
Taper port package, be provided with filter screen in the valve ball, the bottom of the valve body is provided with mounting hole, the bottom of the valve ball
Portion be provided with the corresponding through-hole of the mounting hole, the filter screen passes through mounting hole and through-hole to be installed in valve ball, described
The tail portion of filter screen is provided with the sealing-plug coordinated with mounting hole.
A kind of increase mentioned above has the ball valve of filter screen, wherein, the inner wall of the valve ball is provided with limited block, described
Filter screen can improve the impact force of filter screen resist fluids between limited block, prevent from deforming.
A kind of increase mentioned above has the ball valve of filter screen, wherein, mounting groove, the sealing are provided in the valve body
Circle is arranged in mounting groove, and the outer diameter of the internal diameter of the mounting groove and the sealing ring, which is formed, to be interference fitted, it is ensured that sealing ring is not
It is easy to fall off, improve leakproofness.
A kind of increase mentioned above has the ball valve of filter screen, wherein, bushing and pressure cap are arranged on the valve rod, is improved
The stability of valve rod.
A kind of increase mentioned above has the ball valve of filter screen, wherein, the junction of the handle and valve rod is provided with anti-
Loose nut.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：The phase of mounting groove, sealing ring and valve ball
Interaction makes sealing ring fix more secured, and the better tightness between valve ball, and install filter screen additional to clear up in time
Impurity in fluid improves the quality of fluid, and filter replacement is convenient, fast, only need to extract old filter screen out from body base,
Then new filter screen is installed, just complete replacement, it is time saving and energy saving.
