High-speed controllable fire valve

Abstract

The invention discloses a high-speed controllable fire valve. The valve body is provided with two sealing surfaces, the upper sealing plate is installed on the upper sealing surface of the valve body, and the lower sealing plate is installed under the lower sealing surface of the valve body. The moving end of the valve body is provided with a signal sending device for sending an action signal, and the static end of the valve body is provided with a signal receiving device for receiving the action signal. The receiving device is set as a magnetic induction dry reed switch and a magnetic induction dry reed There are two pieces of metal in the tube for outputting an electric signal. The connecting shaft is installed on the valve body and connected with the lower sealing plate. The upper sealing ring is installed on the valve cover. The O-ring can be replaced by rotating the head of the switch wrench. The valve of the invention is easy to install, has good sealing performance, can automatically detect the switch state of the valve, and is an accurate, high-speed, controllable and intelligent valve.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a high-speed controllable fire valve. Background technique [0002] The fire valve with replaceable upper seal is sealed through the sealing surface of the lower sealing plate and the valve body. It belongs to a special valve for the fire protection industry. The existing fire valve is sealed by a gate plate and an upper seal. When the medium flows into the valve body and the upper seal leaks, the entire pipeline must be closed to replace the upper seal of the valve. This operation is troublesome and time-consuming, resulting in losses. Due to the needs of production and transportation, the butterfly valves used on the container tanks containing chemical raw materials must be accurate, high-speed, controllable, and intelligent. The switch status of the current fire valves must be manually operated by the staff. monitor. During the transportation of the container tank...

[0002] The fire valve with replaceable upper seal is sealed through the sealing surface of the lower sealing plate and the valve body. It belongs to a special valve for the fire protection industry. The existing fire valve is sealed by a gate plate and an upper seal. When the medium flows into the valve body and the upper seal leaks, the entire pipeline must be closed to replace the upper seal of the valve. This operation is troublesome and time-consuming, resulting in losses

Due to the needs of production and transportation, the butterfly valves used on the container tanks containing chemical raw materials must be accurate, high-speed, controllable, and intelligent. The switch status of the current fire valves must be manually operated by the staff. monitor

During the transportation of the container tank, if there is no staff to monitor it all the time or the valve is opened due to the staff mishandling the butterfly valve on the container tank, this may lead to the leakage of the fluid in the container tank, which will cause A certain economic loss, and if the container is filled with toxic fluid, and the staff fails to find that the valve is opened in time, it will cause great harm. Therefore, there is an urgent need for a smart Monitored valve
