Description

Clean ball valve Technical Field The utility model relates to the technical field of valves, in particular to a cleaning ball valve. Background Currently, ball valves are robust valves for many applications, sometimes used under extreme operating conditions including high temperatures and pressures. Such conditions are encountered, for example, in the petroleum industry and various other energy-related fields, such as equipment for storing and recovering solar energy by heating and transporting molten salts. However, the above-mentioned prior art has some drawbacks that in the related fields of high temperature and high pressure energy source such as petroleum industry, a certain amount of fluid remains in the interior and downstream side of the valve when the conventional ball valve is closed. When the system is cool and dry, these residues tend to solidify, which may not only result in the need to apply more force to re-open the valve, but may even cause problems with plugging of the valve itself or downstream process lines. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides a cleaning ball valve. The cleaning ball valve comprises a valve body, a valve core and a valve seat, wherein the valve body is provided with a liquid inlet and a liquid outlet which are communicated, the valve core is provided with an opening state and a closing state, the valve body is provided with a cleaning assembly, the valve core is provided with a movable compression block, the compression block is provided with a closing state close to the valve core and an opening state far away from the valve core, the compression block is provided with a control block for controlling movement, the valve body is provided with a movable cavity which is adaptive to the control block, the valve body is provided with a control port A and a control port B, and the control port A and the control port B are respectively communicated with two ends of the movable cavity and are used for operating the control block to move left and right in the movable cavity. The cleaning assembly comprises an outer flushing port and an inner flushing port, wherein the outer flushing port is arranged adjacent to a liquid outlet, the inner flushing port is close to the inner side of a valve core, an opening is formed in the compression block, a water filling port is formed in the valve body, and when the compression block is in an open state, the opening enables the water filling port to be communicated with the outer flushing port. The valve body is provided with a fluid channel which is communicated with the clearance cavity and the water filling port. The valve body is further provided with a waste liquid port communicated with the inner cavity of the valve core, and the waste liquid port is communicated with the liquid outlet. The utility model further provides that at least two outer flushing ports are uniformly arranged along the circumferential direction of the valve body. The utility model is further provided with an included angle between the inner flushing port and the inner surface of the valve core, an axial extension L of the valve core passing through the peak, a transverse offset Di of the peak and the valve body, a flushing fluid impact position of the outer flushing port and a transverse offset Dii of the valve seat, wherein the included angle between the fluid extension of the outer flushing port and the L is 60-90 degrees, and Dii/Di is 0.4-0.6. In summary, the utility model has the advantages that the residual fluid is quickly and conveniently cleaned through the arrangement of the cleaning component, the arrangement of the pressing block can be well attached to the ball valve to reduce the infiltration gap of the residual fluid caused by the opening and closing valve core, and the pressing block can be far away from the valve core through the operation of the control block, so that the contact surface of the valve core and the pressing block can be deeply cleaned.
