Description
Technical field
The utility model belongs to applicator technical field.In particular it relates to it is a kind of applied to fire-fighting system around flow resistance
The low dry sprinkler of power.
Background technique
Wet sprinkler system has temperature limits, and environment temperature needs between 4 DEG C~70 DEG C.Work as environment temperature
There is frost dangerous when lower than 4 DEG C；When environment temperature is higher than 70 DEG C, in pipe network, there is the danger for destroying pipeline in water vapor aggravation.
In order to meet the needs of cold and high temperature place installation automatic fire extinguishing system, the pipeline of dry sprinkler system is flat
When there is no water, only be in inflated condition.Using the dry sprinkler of sagging installation form, water supply line connection spray head can be ensured
The water that can not be emptied is not retained in vertical standpipe, to avoid that fire-fighting system failure occurs.Dry sprinkler system it is main
Feature be it is anhydrous in pipeline after alarm valve, be not afraid of and freeze, be not afraid of environment temperature height.Therefore, which is suitable for environment temperature
Building and place lower than 4 DEG C and higher than 70 DEG C are mainly used in the fire extinguishing of freezer, high-temperature area, seasonal evacuated area
Protection.
Alarm valve is arranged between the distribution system of water supply and water supply line and separates them for dry sprinkler system, and water does not enter
Protection zone, and dry sprinkler protrudes into protection zone, is thus avoided that water by the influence of temperature in protection zone.Usually, it is located at report
Filled with pressed gas in the distribution system of water supply between alert valve and dry sprinkler, filled in water source to the water supply line between alarm valve
There is pressure water.When the distribution system of water supply has slight gas leakage, tonifying Qi is carried out by air compressor machine, the pressure switch prison being mounted on steam line
Depending on the air pressure change situation of the distribution system of water supply, make the pressure holding balance of pipe network before and after alarm valve.When fire occurs, fiery source temperature
Rising opens dry sprinkler adaptively, and spray head is discharged the pressed gas in the distribution system of water supply first, under the pressure in the distribution system of water supply
Drop.Alarm valve upstream pressure is caused to be greater than downstream pressure, alarm valve, which is opened, makes pressure water in water supply line into people's distribution system of water supply,
Then it is put out a fire by the dry sprinkler ejection having turned on.
Dry sprinkler is the necessaries in dry sprinkler system.Water flow is through portions such as piping, valve and spray heads
When position, it can generate and stream resistance.Existing dry sprinkler, gasket seal and washer seat are after being detached from water inlet, position
Be exactly in immediately ahead of water inlet, it is very big to the barrier effect of water flow, thus can generate it is biggish stream resistance, to fire-fighting efficiency
And effect has an impact.

As shown in figs. 10-11, bracket is made of washer seat interconnecting piece with nozzle connector, and washer seat interconnecting piece is in bending
The frame body of shape, nozzle connector are the cylinder of bracket front end, and frame body and cylinder are connected with each other.Washer seat interconnecting piece is towards rear end
Position is in the arc-shaped of protrusion.The material of bracket uses tin bronze, and while guaranteeing enough intensity, the frame body of bracket can
Accomplish as far as possible smaller, water flowing size has been accomplished bigger, can effectively reduce water flow winding.
As Figure 8-9, washer seat includes the gasket seal interconnecting piece for installing and supporting gasket seal, and is used for
The hinged bearing attachment with bracket；The outer diameter of bearing attachment is less than the outer diameter of gasket seal interconnecting piece.Washer seat is designed as
The small structure in the big front end in rear end, back plan guarantee the installation of gasket seal, and front proof strength while accomplishes minimum as far as possible,
Design ensure that the disturbance to water flow to minimum in this way.The washer seat interconnecting piece rear end of bracket is provided with axis hole, washer seat
Front end is provided with axis hole, and washer seat axis hole is hinged by pin shaft with washer seat interconnecting piece axis hole.Pin shaft hole ensure that washer seat energy
Around holder pivots, water stream channel is got out of the way, reduces water flow winding.Gasket base rear end is provided with the location hole for guiding centering,
The threaded hole design of guiding centering is installed for washer seat.Gasket base rear end is provided with the ring-type for gasket seal to be fixedly mounted
Portion, that is, the flanging design for preventing gasket from falling off.
Because dry sprinkler Design of length is in 80mm~1650mm, so the design length of inner tube is between 0~1610mm.It is long
When metric lattice are 0, cancel setting inner tube, correspondingly cancels setting connector, directly assembled with nozzle by bracket.Length specification
Size makes according to actual needs, while lengthening outer tube, inner tube, and outer length of tube is mutually adapted with inner tube length, remaining zero
Part can be assembled using standard size.In view of in the longer situation of inner tube length, influence to resistance to water-flow finally can
Directly influence discharge coefficient value.So after inner tube length reaches certain specification, as shown in figure 13, in the toe lateral of inner tube
The through-hole for compensating flow, i.e. water flow compensation hole are devised on wall and rear sidewall, to guarantee the water into inner tube
