Remotely controlled spray valve

Abstract

A remotely controlled spray valve comprises a valve body, a valve core and a power module, wherein the power module comprises a piston diaphragm, a piston column, a mounting support, a magnetic monopole, a protective outer cover, a drive device and a mounting box, wherein the mounting box is fixed on the protective outer cover, and the drive device is mounted in the mounting box and comprises a motor, a drive element, a linkage nut, a battery, a logic controller and an SIM communication module. In an actual use process, the logic controller starts or stops the motor according to related instructions, the motor drives the magnetic monopole to move through the linkage nut, the piston column is driven to move under the action of magnetic force, the vertical motion of the piston column can block or loosen a pressure relief hole in the piston diaphragm, the piston diaphragm is controlled under the action of water pressure, and accordingly whether water flow can pass through the valve core is controlled. The spray valve has the advantages that firstly, the improved spray valve has characteristics of being simple in structure and easy to process and assemble; secondly, the opening state of the spray valve can be remotely controlled; thirdly, timely communication alarm is realized.

Description

technical field [0001] The invention belongs to the field of automatic control equipment, in particular to a remote control spray valve. Background technique [0002] In the existing fire protection system, the smoke ion sensor and the glass bubble type water spray head are installed in the room, which can only be applied in higher-level buildings such as hotels, restaurants, and office buildings. When the temperature of the glass bubble type water sprinkler head increases rapidly, the organic solvent in it evaporates, causing the glass bubble to break, and the fire water connected to the glass bubble will spray down, thereby inhibiting the spread of the fire. This disposable device cannot cut off the water source on site, let alone automatically close the valve after the ambient temperature drops, so after the fire is extinguished, the broken glass bubbles will still be sprinkled with water, and a large amount of precious water resources will be wasted. [0003] In order t...

Problems solved by technology

This one-time device cannot cut off the water source on site, let alone automatically close the valve after the ambient temperature drops, so after the fire is extinguished, the broken glass bubbles will still be sprinkled with water, and a large amount of precious water resources will be wasted.

[0003] In order to solve this problem, automatic sprinkler valves with different structures have been continuously proposed in the prior art. On the one hand, the existing automatic sprinkler valves have complex structures and high manufacturing costs. On the other hand, the existing automatic sprinkler valves cannot Remote control, secondly, the existing automatic sprinkler valve does not have timely alarm function
