Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
It is novel.
Refering to fig. 1 shown in -3, the utility model provides following examples.
A kind of antifreeze device for detecting water pressure of fire hydrant antidetonation, including sequentially connected pressure sensor 6, pressure sensor
Connector 5, hose 4, hollow bolt 3 and diaphragm connector 2, the diaphragm connector inside are equipped with diaphragm；It is filled in the hose anti-
Antifreezing liquid is shaken, fire hydrant hydraulic pressure passes to pressure sensor by the antidetonation antifreezing liquid in diaphragm, hose.It should illustrate
Be due to being directly to detect hydraulic pressure by pressure sensor in the prior art, hydraulic pressure is made to directly act on pressure sensor, thus
Sensor is caused stress to be easily damaged.And in the present embodiment, hydraulic pressure passes sequentially through diaphragm and antidetonation antifreezing liquid is transmitted, and keeps away
Exempted from pressure sensor 6 directly is caused to damage by impact, improves the reliability of pressure detecting.It is understood that the pressure
After force snesor 6, pressure sensor connector 5, hose 4, hollow bolt 3 and diaphragm connector 2 are attached, it is a kind of for being formed by
The relationship of connection, under the shape body that works, antidetonation antifreezing liquid is riddled in the channel formed between pressure sensor and diaphragm.
Further, installation knot of the antifreeze device for detecting water pressure of the antidetonation on fire hydrant is schematically provided in Fig. 1
Structure.Specifically, the structure design of existing fire hydrant can be used in the fire hydrant main body in the present embodiment comprising be set to fire hydrant
Main intracorporal screw bolt seat, fire hydrant water inlet sealing cover and connect the connecting rod of the screw bolt seat and sealing cover, the connection
