Description

A sprinkler head with good water impact resistance

technical field

The utility model relates to a sprinkler head with good water impact resistance.

Background technique

In the automatic fire extinguishing system, sprinklers, as one of the patron saints of people's lives and property, are responsible for the two missions of monitoring fires and extinguishing fires. Each sprinkler has a specific protection area. When a fire occurs, water flows through the The splash plate of the sprinkler sprinkles out to extinguish the fire, and the fire water is evenly sprinkled through the sprinkler to control the fire in the area. Currently commonly used sprinklers are usually divided into pendant sprinklers, upright sprinklers, ordinary sprinklers, side wall sprinklers, etc., among which the pendant sprinklers are the most widely used sprinklers. The pendant sprinkler head is usually assembled by support frame, glass ball, seal, glass ball seat, set screw and splash plate, etc. It is mainly used in light and medium dangerous places and commercial places, such as banks, hotels, shopping malls, etc. center etc. When in use, it is installed on the water supply branch pipe, and 80-100% of the total water can be sprayed to the ground, and the sprinkling shape is a parabolic shape. A plurality of fire extinguishers are connected to each other through connectors to form a whole fire extinguisher. Refers to a group composed of multiple fire extinguishing (device) devices, which are connected to each other according to pre-programmed rules through connectors to form a whole. According to the set starting mode (temperature sensing, smoke sensing, etc.), the fire extinguishers (devices) in the system are started individually, multiplely or simultaneously to achieve a fire extinguishing system that cannot be completed by a single fire extinguisher (devices) alone. A single fire extinguishing device is itself a fire suppression system. The various components in the fire extinguishing system are assembled with each other, interconnected and restricted each other, forming a relatively stable connection mode and organizational structure, and achieving a fire extinguishing effect that ordinary fire extinguishers cannot achieve. Generally, this type of fire extinguishing system: bulky, many components, large fire extinguishing dose, many powder outlets and various orientations.

The current existing fire extinguishing nozzles have poor water impact resistance, poor thermal stability and low water pressure resistance.

A glass ball is provided in the rubber sleeve, and a polyvinyl chloride layer is provided outside the glass ball. Both sides of the base plate are welded with metal rings, the threaded plug is provided with shrapnel, the top of the shrapnel is bent, the middle of the metal ring is provided with a raised part, and the metal ring is provided with a splash plate. A screw is installed in the middle of the splash pan, and the screw penetrates through the splash pan and is installed in the metal ring.

Preferably, the top of the glass ball is in contact with the shrapnel, and pressing the shrapnel can damage the glass ball.

Preferably, the bottom of the raised portion is in contact with the elastic piece, and the raised portion can limit the position of the glass ball under the elastic piece.

Preferably, a gasket is installed between the screw and the splash plate, and the gasket keeps the screw compactly installed.

Preferably, reinforcing ribs are provided on the surface of the metal ring, and the reinforcing ribs can improve the structural strength of the metal ring.

Preferably, the reinforcing rib is welded to the metal ring to keep the reinforcing rib structure firm.

Preferably, circular holes are distributed on the splash plate in an annular array, so that a part of the water can be sprayed out from the circular holes to keep the spraying uniform.

The technical effect of the utility model is mainly reflected in the following aspects: the set protrusion can limit the position of the glass ball under the shrapnel, so that the position of the glass ball is firm, and the performance of water impact resistance is good; the outside of the set glass ball is provided with polyvinyl chloride Layer, the high temperature resistance effect of the polyvinyl chloride layer is maintained, and the thermal stability of the structure is maintained; the rubber sleeve is arranged in the set through hole, and the contact with the polyvinyl chloride layer outside the glass ball can achieve a sealing effect, so that the water pressure resistance is high. Good water impact resistance.

detailed description

Below in conjunction with the accompanying drawings, the specific implementation of the utility model will be further described in detail, so as to make the technical solution of the utility model easier to understand and grasp.

A sprinkler head with good water impact resistance, comprising a bottom plate 1, a threaded pipe 2 and a threaded plug 3, the threaded pipe 2 is welded under the bottom plate 1, the threaded plug 3 is arranged in the bottom plate 1, and the corresponding position of the bottom plate 1 is set There are threaded holes to install the threaded plug 3. The threaded plug 3 is threadedly connected with the bottom plate 1, and a through hole 4 is provided in the middle of the threaded plug 3, and the through hole 4 allows water to pass through. A rubber sleeve 5 is arranged in the through hole 4, and the rubber sleeve 5 keeps the glass ball 6 installed inside to achieve a sealing effect. The rubber sleeve 5 is glued to the threaded plug 3 and fixed with epoxy resin glue. A glass bulb 6 is arranged inside the rubber sleeve 5 , and a polyvinyl chloride layer 7 is arranged on the outside of the glass bulb 6 , and the polyvinyl chloride layer 7 is fixed on the outside of the glass bulb 6 by epoxy glue.
