Problems solved by technology
[0004] The purpose of the present invention is to solve the problem that the existing pilot-operated electromagnetic ball valve does not have the ability to filter the liquid in the valve body, so that the impurities in the liquid accumulate in the valve body for a long time, and the body of the closed ball valve is easily stuck, and the closed ball valve is assembled. The main body cannot be closed, and in severe cold weather, the liquid is easy to freeze and cannot circulate, and a pilot electromagnetic ball valve is proposed

The invention discloses a pilot-operated type electromagnetic ball valve. The pilot-operated type electromagnetic ball valve comprises an electromagnetic ball valve body, an electromagnetic central control module is fixedly installed at the top end of the electromagnetic ball valve body, and a transmission rod is fixedly installed in the electromagnetic ball valve body. According to the pilot-operated type electromagnetic ball valve, filtering is carried out through a multi-mesh filter screen in a connecting pipe, so that impurity particles in liquid are filtered and separated, and the situation that the closed ball valve body cannot be closed due to the fact that the impurity particles in the liquid are accumulated in the electromagnetic ball valve body and are accumulated for a long time to clamp the closed ball valve body is prevented; a heating pipe ring is installed on the inner wall of a sleeving round pipe, the connecting pipe of the device can be heated and subjected to heat preservation, the situation that the liquid cannot flow due to the fact that in cold weather, the liquid in the device is frozen due to the influence of severe cold is prevented; and an arc-shaped pressing plate can be driven to move in a telescopic mode by rotating a first hand-screwed bolt, installation and connection of the sleeving round pipe and the connecting pipe are facilitated, and the position of the sleeving round pipe can be flexibly adjusted.
Description
technical field [0001] The invention relates to the technical field of electromagnetic ball equipment, in particular to a pilot type electromagnetic ball valve. Background technique [0002] Pilot-operated solenoid valve, when energized, relies on electromagnetic force to lift the valve stem, and the pilot valve port opens. At this time, the upper chamber of the solenoid valve releases pressure through the pilot hole, forming an upper and lower pressure difference around the main valve core. Down, the fluid pressure pushes the main valve core to move upward to open the main valve port. When the power is off, under the action of the spring force and the gravity of the main valve core, the valve stem resets, the pilot hole is closed, the main valve core moves downward, and the main valve port Closed, the pressure in the upper chamber of the solenoid valve increases, the fluid pressure pressurizes the main valve core, and the seal is better. The solenoid ball valve is a physica...
