Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a new ball valve. Background Art

[0002] A ball valve is a valve whose opening and closing member (ball) is driven by a valve stem and rotates around its axis. It can also be used for regulating and controlling fluids. The hard-sealed V-shaped ball valve, with its V-shaped core and carbide-clad metal seat, creates a strong shear force, making it particularly suitable for media containing fibers and tiny solid particles. Multi-way ball valves, on the other hand, can flexibly control the confluence, diversion, and direction of flow in pipelines and can also close any channel while connecting the other two.

[0003] After long-term use, a lot of impurities will accumulate inside the ball valve, which will cause it to clog. Therefore, in view of the above situation, there is an urgent need to develop a ball valve that is easy to disassemble and clean in order to overcome the shortcomings in current practical applications and meet current needs. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a new ball valve which is easy to disassemble and clean.

[0005] The objectives of the present utility model can be achieved through the following technical solutions: a new type of ball valve, comprising a ball valve body, a valve ball is arranged in the ball valve body, a valve stem for controlling the rotation of the valve ball is arranged on the ball valve body, an inlet pipe for water intake and an outlet pipe for water discharge are arranged on the ball valve body, and it is characterized in that a filtering device is arranged on the ball valve body relative to the water inlet pipe, a fixing part for installing the filtering device is provided on the ball valve body, the filtering device consists of a mounting part, a fixing frame and a mounting part, a sealing ring is provided on the mounting part, a sealing groove that matches the sealing ring is provided on the fixing part, a positioning component for fixing the filtering device is provided on the mounting part, the positioning component includes a positioning part and a reset spring, and positioning holes that match the positioning part are provided on the fixing part and the sealing ring.

[0006] In the above-mentioned new ball valve, an installation groove for installing the positioning component is provided on the installation portion, one end of the positioning member extends out of the installation portion and is connected to the pulling portion, and the other end of the positioning member extends out of the installation groove and cooperates with the sealing ring and the positioning hole on the fixing portion to fix the filter device on the ball valve body.

[0007] In the above-mentioned novel ball valve, a filter screen for filtering is provided on the fixed frame.

[0008] In the above-mentioned novel ball valve, four filtering devices are provided and are distributed in pairs on both sides of the mounting portion.

[0009] Compared with the existing technology, this new ball valve filters the liquid entering the valve body by arranging a filter device at the position of the water inlet pipe, and the filter device is fixed to the ball valve body through a positioning component, which is convenient for staff to disassemble and replace it.
