Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.nullAs shown in Figures 1 to 4: one is opened soon from letting out fire monitor，Including monitor body 4，Monitor body 4 is provided with nozzle 1，Nozzle 1 is then provided with Pressure gauge 2 and control handle 3，The lower end of monitor body 4 is provided with gun platform 5，The lower section of gun platform 5 is then connected by extension pipe 8 key 12，The water inlet of described key 12 bottom is provided with defecator 15，Gun platform 5 is rotatably connected to cam switch 6，The lower end of this cam switch 6 is provided with depression bar 7，The top of depression bar 7 matches with the bottom surface of cam switch 6，The top of extension pipe 8 is connected with gun platform 5，The bottom of extension pipe 8 is connected with key 12，The connecting rod 9 being connected with depression bar 7 it is provided with in extension pipe 8，And this connecting rod 9 is positioned at key 12，The bottom of connecting rod 9 is connected with valve rod 11 by contiguous block 18，The bottom of valve rod 11 is provided with Spool assembly 14，Here Spool assembly 14 includes secondary valve core 19 and one-level spool 20，Wherein secondary valve core 19 is fixed on valve rod 11 bottom，One-level spool 20 is then actively socketed on valve rod 11，Back-moving spring 10 also it is socketed with on valve rod 11 between contiguous block 18 and one-level spool 20，One-level spool 20 is additionally provided with perforate，The valve seat 13 matched with one-level spool 20 it is additionally provided with in key 12，Described contiguous block 18 is additionally provided with automatic draining mechanism 17，The bottom of described automatic draining mechanism 17 matches with Auto-drainage valve seat 16，And Auto-drainage valve seat 16 is connected with the discharge pipe line being opened in key 12 side.
Opening soon from letting out the work process of fire monitor of this utility model embodiment is as follows: when this product is under duty (not using), the cam switch 6 of the cylindrical shape closed chamber being positioned on gun platform 5 is in state as shown in Figure 1: now the top of depression bar 7 is in uppermost position in fig-ure, depression bar 7 and connecting rod 9, valve rod 11 and Spool assembly 14 are in uppermost position in fig-ure, now the one-level spool 20 in Spool assembly 14 is in close contact at valve seat 13, it is internal that press water in pipeline will not enter key 12, this advantage along means of press seals mode is that pipeline inner pressure is the biggest, sealing effectiveness is the best, overcome the problem that the most inverse the biggest sealing of pressure sealing structure pressure is more difficult to；
When needs work, with spanner rotary cam switch 6, cam switch 6 is made to be threaded to position as shown in Figure 2, now the top of depression bar 7 moves downward under the compressing of cam switch 6, thus drive the Spool assembly 14(i.e. one-level spool 20 being attached to and secondary valve core 19 through connecting rod 9, valve rod 11) move downward, in motor process, first secondary valve core 19 departs from and the contacting of one-level spool 20, make current can flow into key 12 by the space between secondary valve core 19 and one-level spool 20 through being opened in the perforate on one-level spool 20；When depression bar 7 continues to move downward, one-level spool 20 disengaging contacts with valve seat 13, current can flow into defeated key 12 by the accent between one-level spool 20 and valve seat 13, so, water flow pressure acts on each stress surface of two-stage spool and valve seat 13, reducing flow velocity because unexpected being varied multiple times flows to, resistance to water-flow increases the most simultaneously, and water pressure higher in making pipe network reduces；When water pressure fluctuations in pipe network, each stress of two-stage spool changes the most therewith, by the deformation elastic force of back-moving spring 10, the gap between one-level spool 20 and secondary valve core 19 gap, one-level spool 20 and valve seat 13 each other can be regulated voluntarily, not only can obtain the water flow pressure for fire fighter's safe handling, also can automatically adjust, thus ensure that the hydraulic pressure flowed out from outlet (nozzle 1 of monitor body 4) remains constant.In the process, the automatic draining mechanism 17 being connected with valve rod 11 side is in close contact with the contact surface of Auto-drainage valve seat 16, it is achieved that seal at this.
After fire-fighting work completes, reversely rotate cam switch 6 with instrument, make one-level spool 20 and secondary valve core 19 again be in close contact with valve seat 13, it is achieved seal.
When this product is under duty (not using) (such as Fig. 1), the automatic draining mechanism 17 being connected with valve rod 11 by contiguous block 17 and the contact surface of Auto-drainage valve seat 16 are separated, the remaining water of fire hydrant inner chamber flows out through Auto-drainage valve seat, fire hydrant is made to play Auto-drainage effect, to reach the effect of preventing freeze in winter.
