Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 , figure 2 , image 3 As shown, the ball valve with filter of the present invention includes a valve body 1, a valve ball 2, and a valve actuator 3, and the valve body 1 is provided with a valve ball 2 inside.

[0031] The upper end of the valve body 1 is provided with the valve actuator 3 connected to the valve ball 2. The valve actuator 3 is a mechanism that can drive the valve to fully open or fully close. The existing technology is adopted, such as electric 90° single-rotary actuator. Institutions, fluid-driven or linear output actuators, fluid-driven partial single-turn actuators.

[0032] Such as image 3 As shown, the center of the valve ball 2 has a through hole 4, and one end of the through hole 4 is provided with a filter screen 5. The shape of the filter screen 5 is preferably horn-shaped or the horn-shaped with ...

Abstract

The invention provides a ball valve with a filter screen, which comprises a valve body, a valve ball body and an actuating mechanism of the valve. The valve ball body is arranged inside the valve body, a through hole is arranged in the center of the valve ball body; one end of the through hole is provided with the filter screen; the upper end of the valve body is provided with the actuating mechanism of the valve, which is connected with the valve ball body; two flow passage openings opposite to each other at an angle of 180 degrees are arranged on two sides of the valve body in the horizontal direction; a cleaning opening at an opposite angle of 90 degrees with respect to the flow passage openings is arranged on another side of the valve body in the horizontal direction; a pipeline externally connected to the cleaning opening is provided with a filter screen cleaning mechanism; the valve body is further provided with a drain opening; and a pipeline externally connected to the drain opening is provided with a drain valve. The ball valve with the filter screen has double functions of the valve and the filter; the fluid resistance in the pipeline is not increased after the valve is provided with the purpose-made filter screen, the pressure difference between the front and the back of the new valve is zero, wherein the disassembly, the assembly and the replacement of the filter screen part are quick, convenient and reliable, the labor intensity is reduced, the labor cost is saved, and the halt loss of the heater set is also reduced.

Description

technical field [0001] The invention relates to a ball valve, in particular to a ball valve with filter. Background technique [0002] In the urban heating system, the heating unit→pipe network→user mode is often adopted, in which the heating unit is the source of heat energy exchange and circulation. In the heating unit installation, in addition to configuring heat exchangers, circulating pumps, pipe network temperature, pressure and flow regulators, many welded ball valves are installed to control pipeline fluid (working medium). Due to the limited construction conditions of the pipeline network, the cleanliness of the pipeline is poor, and there are many metal or non-metal foreign objects. If the numerous impurities and foreign objects are not removed regularly and in time, it will seriously affect the life of the pipeline network equipment and the safety and reliability of the pipeline network operation. Therefore, a filter must be installed on the heating unit. [000...
