Abstract
A kind of spiral water atomizer that can stretch is made up of pipe joint, spool, protective sleeve, fire-retardant sealing ring and nozzle; Be provided with seal groove in protective sleeve, fire-retardant sealing ring is arranged in seal groove, and nozzle is arranged in protective sleeve, and protective sleeve and pipe joint are connected together by internal and external screw thread; Spool correspondence is arranged on the other end of pipe joint; Nozzle is free-extension in protective sleeve and pipe joint; The utility model adds protective sleeve, spool and sealing ring, and nozzle becomes can move up and down from maintaining static, thus achieves hiding and stretching out function of nozzle; When needs carry out sprinkling fire-distinguishing, nozzle stretches out under fluid pressure effect; When normal condition does not need spray, manually promote nozzle, nozzle is hidden in protective sleeve, and then eliminate safe hidden trouble, achieve the protective effect to passenger.
Description
Technical field
The utility model belongs to nozzle technology field, and what be specifically related to is a kind of spiral water atomizer that can stretch, and is mainly used in public traffic vehicle passenger cabin fixed fire extinguishing system and indoor automatic sprinkler fire-extinguishing system.
Background technology
nozzle in the existing nozzle assembly of current public traffic vehicle passenger cabin fixed fire extinguishing system and pipe joint are directly connected (as shown in Figure 1) by screw thread; Its nozzle can not adjust up and down, the exposed top, main cabin at mass transportation facilities of whole nozzle, and is exposed in main cabin outside its head pointed end, is easy to damage passenger, there is serious potential safety hazard.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of concealment effect good, the spiral water atomizer that can stretch.
This nozzle utilizes the pressure of the liquid such as extinguishing chemical to nozzle to be used for realizing hiding and extend action of nozzle; Its hide actions make use of groove between sealing ring and nozzle and frictional force effect; And to reach hiding homing action be realize manually.
The utility model is achieved through the following technical solutions: a kind of spiral water atomizer that can stretch, is made up of pipe joint, spool, protective sleeve, fire-retardant sealing ring and nozzle; Seal groove is provided with in described protective sleeve, fire-retardant sealing ring is arranged in seal groove, and nozzle is arranged in protective sleeve, and the outer wall of described protective sleeve is provided with external screw thread, inwall one end of pipe joint is provided with internal thread, and this protective sleeve and pipe joint are connected together by internal and external screw thread; Spool correspondence is arranged on the other end of pipe joint; Nozzle is free-extension in protective sleeve and pipe joint.
The external diameter of described nozzle is provided with groove.
Nozzle, when not carrying out fire-fighting spraying, by the groove on fire-retardant sealing ring and nozzle od and frictional force, makes nozzle be hidden in protective sleeve, thus achieves the protection to passenger, eliminate potential safety hazard; When needs carry out spray fire-fighting, in pipe joint liquid extinguisher pressure effect under (now spool closedown), nozzle overcomes fire-retardant sealing ring and the frictional force between it moves downward and stretches out protective sleeve, and then nozzle stretches out and realizes sprinkling fire-distinguishing function.
The beneficial effects of the utility model embody and are: compared with prior art, the utility model adds protective sleeve, spool and sealing ring, and nozzle becomes can move up and down from maintaining static, thus achieve hiding and stretching out function of nozzle; When needs carry out sprinkling fire-distinguishing, nozzle stretches out under fluid pressure effect; When normal condition does not need spray, manually promote nozzle, nozzle is hidden in protective sleeve, and then eliminate safe hidden trouble, achieve the protective effect to passenger.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is existing spiral water atomizing nozzle structure schematic diagram.
Fig. 2 is the utility model nozzle hidden state structural representation.
Fig. 3 is that the utility model nozzle stretches out status architecture schematic diagram.
In figure: 1 pipe joint, 2 protective sleeves, 3 nozzles, 4 fire-retardant sealing rings, 5 spools, 6 pipe joints, 7 nozzles.
Detailed description of the invention
As shown in Figure 2,3, a kind of spiral water atomizer that can stretch, is made up of pipe joint 1, spool 5, protective sleeve 2, fire-retardant sealing ring 4 and nozzle 3; The erection sequence of this nozzle is contained in the seal groove of protective sleeve 2 by fire-retardant sealing ring 4, then nozzle 3 is loaded in protective sleeve 2, the assembly again part protective sleeve 2, nozzle 3, fire-retardant sealing ring 4 formed by pipe joint 1 and protective sleeve 2 sealing thread be connected and fixed, finally spool 5 is threaded connection the upper surface being contained in pipe joint 1; Adjustment spool 5 position, ensures that nozzle 3 is when extreme higher position (be hidden into the inside), and spool 5 is closed tight the endoporus of nozzle 3 (namely with) and realized closed.
The utility model nozzle is on the pipe joint of the extinguishing chemical transfer pipeline of public traffic vehicle passenger cabin fixed fire extinguishing system, by sealing thread, protective sleeve is fixedly connected with spool, nozzle is arranged in protective sleeve, is realized the positioning function of sealing and hidden state by fire-retardant sealing ring; By the precision-fit of protective sleeve inner chamber and nozzle od region of interest, ensure that the proper exercise track of nozzle in protective sleeve; By being fixed on closing of spool on pipe joint and nozzle bore, opening force required when ensure that nozzle starts to stretch out; Along with stretching out downwards of nozzle, spool is opened, and carries out Liquid transfer preparation for starting spray; Fire-fighting spraying terminates, and manually nozzle is pushed jacket internal, thus realizes the function hiding nozzle, and spool is closed simultaneously, for next nozzle stretches out ready.
