Anti-clogging quick spray equipment

Abstract

The invention belongs to the technical field of fire-fighting equipment, in particular anti-clogging fast spray equipment, comprising an inner conduit, an outer conduit and a spray head; the outer conduit is sleeved on the outside of the inner conduit; A guide block is connected; a spray head is provided under the guide block; an adjustment hole is opened on the surface of the inner conduit close to the position of the spray head; an adjustment block is slidably connected to the inside of the adjustment hole; the adjustment block Evenly arranged springs are fixed on the upper surface of the upper surface; through the present invention, the effective isolation between the pipeline used in the spray equipment and the external environment is effectively realized, and the multi-layer structure design avoids direct contact between the inner conduit and the external environment , reduce the risk of freezing of water inside the inner conduit, avoid problems such as the transistor of the sprinkler head being squeezed and bursting, and at the same time, through the adjustment block, the inner conduit and the outer conduit in the silted state are directly connected, thus ensuring the sprinkler head. The flow rate of water spray meets the requirements of fire protection.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to anti-clogging rapid spray equipment. Background technique [0002] The fire sprinkler is used in the fire sprinkler system. When a fire breaks out, the water is sprayed out through the sprinkler splash plate to extinguish the fire. It is divided into a pendant sprinkler, a vertical sprinkler, a common sprinkler, and a side wall sprinkler Nozzle etc. [0003] According to CN106249552B, a spraying device, the spraying device provided by the invention greatly improves the practicability and flexibility, facilitates equipment adjustment, failure analysis and engineering experiments, and at the same time greatly improves engineering efficiency and reduces poor spraying. The process yield rate is improved, and the production cost is reduced. [0004] However, in the prior art, under winter conditions, the water inside the rapid sprinkler equipment is easy to freeze, a...

Problems solved by technology

[0004] However, in the prior art, under winter conditions, the water inside the rapid sprinkler equipment is easy to freeze, and because the density of ice is lower than that of water, the frozen rapid sprinkler equipment will be subjected to a large expansion force, making the spray The glass tube inside the shower head is subject to high pressure, which may easily cause the glass tube to burst, which in turn will cause damage to the rapid spraying equipment. Due to the relatively dry winter climate and frequent fires, if the sprinkler head is damaged in extremely cold conditions, if it is not repaired in time Replacement will greatly increase the risk of fire protection and threaten the safety of people's lives and property. At the same time, the frozen fire water pipes will also prevent the normal spraying of fire water. By continuously flowing the heating fluid inside the pipeline, the winter heating of the fire-fighting water pipe can be realized, and the water inside the pipeline can be avoided from freezing. Poor, on the other hand, the heat is easily lost, which increases the cost of providing heat energy. At the same time, the inner wall of the fire water pipe after heating is easy to adhere to a large amount of water stains. If it is not cleaned for a long time, it is easy to cause half blockage or full blockage , affecting normal fire water safety and other issues
