Description

Erect type split sprinkler tip

Technical field

This utility model relates to a kind of shower nozzle, in particulars relate to the sprinkler tip of a kind of automatic sprinkler system.

Background technology

Automatic sprinkling fire-extinguishing shower nozzle is a kind of conventional fire-fighting equipment, Patent No. 200820140093.8, entitled " separate type Automatic water-spraying fire-extinguishing system sprinkling nozzle " utility model patent disclosed in sprinkler tip, including valve body, flap, be arranged at Deluge system on valve body and the automatic sprinkler being connected with valve body by connecting tube, flap is arranged in valve body, due to enclosed spray Head is arranged towards the direction away from top board, if valve body is long, then automatic sprinkler splash box can be more than 150mm with the distance of top board, It is unfavorable for the response of shower nozzle；It addition, utilize flap to seal, it is likely to result in leaking before and after action；Further, if valve Body internal rust, only by pipe network water pressure it cannot be guaranteed that can smooth opening bypass conduit.

Utility model content

The purpose of this utility model is to provide a kind of erect type split sprinkler tip, and its automatic sprinkler is less with the distance of top board, has It is beneficial to the response of automatic sprinkler, and shower nozzle action is more reliable.

To achieve these goals, technical solution of the present utility model is: a kind of erect type split sprinkler tip, including three Siphunculus, tee T lower end is used for connecting water source, and described tee T right-hand member connects open sprinkler head, the supervisor of described tee T Upper end connects has sealed sprinkler head, described supervisor's inwall to be provided with lower location dish, and lower location disk center is provided with through hole, and described three Being provided with piston rod in the supervisor of siphunculus, described piston rod passes in the through hole from the dish of described lower location, and described piston rod Lower end is fixed with piston, is fixedly arranged in the middle of location dish, and described piston adapts with described supervisor lower end, described upper cover of piston rod Have stage clip, described stage clip upper end to be resisted against described upper location dish upper and lower end to be resisted against on the dish of described lower location, on described piston rod End is resisted against on the glass bead of described sealed sprinkler head.

This utility model erect type split sprinkler tip, wherein, described piston lower surface is provided with sealing ring.

This utility model erect type split sprinkler tip, wherein, the through hole on the dish of described lower location is slightly larger than outside described piston rod Footpath.

Use after such scheme, compared with prior art due to the supervisor of tee T of this utility model erect type split sprinkler tip Upper end connects sealed sprinkler head, and therefore sealed sprinkler head and top board is close together, once has fire to occur, and enclosed is spilt Sprinkler head can quickly respond, further, since be provided with piston rod in the supervisor of tee T, piston-rod lower end is fixed with piston, lives Being cased with stage clip on stopper rod, after the glass bead of sealed sprinkler head ruptures, even if there being problem of rustiness in tee T, piston rod also may be used Action under the drive of stage clip, relatively reliable during use.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model erect type split sprinkler tip.

Detailed description of the invention

As it is shown in figure 1, this utility model erect type split sprinkler tip includes that tee T 11, tee T 11 lower end are used for connecting Water source, tee T 11 right-hand member is connected by connecting tube 21 open sprinkler head 12, and supervisor 111 upper end of tee T 11 is even Being connected to sealed sprinkler head 13, be responsible for 111 inwalls and be provided with lower location dish 16, dish 16 center, lower location is provided with through hole, threeway Being provided with piston rod 14 in the supervisor 111 of pipe 11, piston rod 14 passes in the through hole on lower location dish 16, and piston Bar 14 lower end has been bolted piston 15, has been fixedly arranged in the middle of location dish 17, under the size of piston 15, shape and supervisor The size of inner wall of end, shape adapt, and when being cased with stage clip 18 on described piston rod 14, described stage clip 18 upper end is resisted against institute Stating location dish 17 upper and lower end to be resisted against on described lower location dish 16, described piston rod 14 upper end is resisted against described enclosed and spills On the glass bead of sprinkler head 13, piston 15 lower surface is provided with sealing ring 19.

When shower nozzle is in quasi-operating status, the upper end of piston rod 14 props up the glass bead on sealed sprinkler head 13, lower end Piston 15 and sealing ring 19 are by tee T 11 lower end closed；When a fire, heat smoke is internal with sealed sprinkler head 13 Glass bead generation heat convection, glass bead is by after thermal fracture, and piston rod 14 is under the effect of stage clip and range pipe hydraulic pressure, whole Body moves up, and top is against at the splash box of sealed sprinkler head, has one end of piston to be against lower location Pan16Chu, opens Threeway side pipe, passes water through connecting tube and is sprayed by open sprinkler head 12, and the upper piston 15 moved and sealing ring 19 are blocked down simultaneously The hollow space of location dish, plays sealing function, it is ensured that current are not flowed out by threeway supervisor (left side), are all spilt by open type Sprinkler head 12 flows out.

Through hole on lower location dish 16, slightly larger than the external diameter of piston rod 14, plays spacing, righting during piston rod about 14 Effect.

Embodiment described above is only to be described preferred implementation of the present utility model, not to model of the present utility model Enclosing and be defined, on the premise of without departing from this utility model design spirit, this area ordinary skill technical staff is new to this practicality Various deformation that the technical scheme of type is made and improvement, all should fall in the protection domain that claims of the present utility model determine.
