329, the setting of closeouts 4, for can achieve better seal effect, specifically when sealing closure plate 326 seals
Seal process is as follows:
When sealing closure plate 326 is moved downward and sealed, the movement of mobile bar 45, the movement meeting of mobile bar 45 can be push
It is moved into first through hole 325 by connecting rod 44 with plugging block 41, and sealing shroud 43 is contradicted in first through hole 325
Side wall on, to play the effect for being sealed first through hole 325；
First through hole 329 realizes that the working principle blocked is consistent with first through hole 325 by closeouts 4；
In the present embodiment, the setting of support spring 47 is used for 41 reset response of plugging block, which is in seal plug
When 326 non-plugging device of plate；
In order to guarantee that mobile bar 45 can be moved smoothly, mobile bar 45 is fixedly installed far from one end of first through hole 325
Second anti-sticking raised 46, the second anti-sticking raised 46 setting, when can contradict downwards mobile bar 45 to avoid seal plug plate 326, quilt
The case where blocking exists；
Meanwhile one end of plugging block 41 towards first through hole 325 is fixedly installed first anti-sticking raised 42, the first anti-card convex
42 setting is played, it can be to avoid plugging block 41 to when moving in first through hole 325, the case where being stuck.
As shown in fig. 6, one end of connecting rod 44 vertical bar towards first through hole 325 is connected with one end of guidance set 49, lead
On the inner cavity side plate for being fixed at seal box 321 to the other end of component 49, guidance set 49 includes guide rod 491 and guiding
Cylinder 492,491 activity of guide rod is plugged on guide cylinder 492；
In the present embodiment, the setting of guidance set 49 is to play the role of guiding and support.
The invention has the advantages that:
In the present invention, by being additionally arranged rectangle connector 32, rectangle connection between tubular type fire hydrant 1 and linking pipeline 33
The setting of part 32 can play the effect of leakproof, meanwhile, 32 structure of rectangle connector design is simple, reasonable, can be by light
Just it adjusts, realizes the effect of switch, and the adjustment process is time saving and energy saving.
What the embodiment of the present invention was announced is preferred embodiment, and however, it is not limited to this, the ordinary skill people of this field
Member, easily according to above-described embodiment, understands spirit of the invention, and make different amplification and variation, but as long as not departing from this
The spirit of invention, all within the scope of the present invention.
