Especially for building fire protection facilities, the fire hydrant pressure testing device can detect the static water pressure and outlet water pressure of the fire hydrant, thereby ensuring the normal operation of the fire protection system.

[0003] However, the connection between the fire hydrant water pressure testing device and the fire hydrant is fixed at the current market. During installation, the entire device needs to be screwed and rotated, which makes it inconvenient to control the display direction of the pressure gauge and the installation is relatively cumbersome.

[0008] Preferably, a sealing gasket is provided inside the sleeve, the sleeve is movably fitted on the outer wall of the main water outlet pipe, and the output end of the main water outlet pipe is movably connected to the sealing gasket.

[0009] Preferably, the two sliding holes are sleeved on the outside of the two auxiliary water outlet pipes.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This building fire protection facility water pressure testing device works by placing a fixed frame around the outside of the auxiliary water outlet pipe, inserting a rod into the inside of the fixed frame, tightening the bolts, and securing the fixed frame to the outer wall of the fire hydrant body. At this time, the sleeve is fitted onto the outer wall of the auxiliary water outlet pipe, and the water guide cavity enters the pressure gauge, thus achieving the effect of testing the water pressure of the fire hydrant body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example:

[0019] Please refer to Figures 1-3.

[0020] A water pressure testing device for building fire protection facilities includes two fixed frames 1. Insert rods 2 are movably inserted into the interior of each fixed frame 1. An annular frame 3 is fixedly installed between the two insert rods 2. A sleeve 4 is rotatably connected inside the annular frame 3. A fixing ring 5 is fixedly installed on the right side of the sleeve 4. A pressure gauge 6 is fixedly installed inside the fixing ring 5. Connecting columns 7 are fixedly installed inside each of the two fixed frames 1. Bolts 8 are threadedly connected to the interior of each of the two connecting columns 7. Sliding holes 9 are opened inside each of the two fixed frames 1. A fire hydrant body 10 is arranged between the two fixed frames 1. Auxiliary water outlet pipes 11 are fixedly connected to both sides of the fire hydrant body 10. A main water outlet pipe 12 is fixedly connected to the interior of the fire hydrant body 10.

[0021] Specifically, when a water pressure test is required on the main outlet pipe 12 of the fire hydrant body 10, first remove the plug on the main outlet pipe 12, then first place the fixing frame 1 on the outside of the auxiliary outlet pipe 11, then insert the insertion rod 2 into the inside of the fixing frame 1, and then tighten the bolt 8. The bolt 8 will press against the outer wall of the auxiliary outlet pipe 11, and then the fixing frame 1 will be snapped into the outer wall of the fire hydrant body 10. At this time, the sleeve 4 is placed on the outer wall of the auxiliary outlet pipe 11. After tightening, the sleeve 4 is fixed to the outside of the main outlet pipe 12, and then the fire hydrant body 10 is installed. When the hydrant body 10 is opened, the water in the main outlet pipe 12 enters the water guiding chamber and then enters the pressure gauge 6, which can detect the water pressure of the hydrant body 10 and achieve convenient assembly. Because the annular frame 3 and the sleeve 4 are rotatably connected together, the position of the pressure gauge 6 can be adjusted by rotating the fixing ring 5 during installation. This solves the problem that the connection between the fire hydrant water pressure detection device and the fire hydrant is fixed, and the entire device needs to be rotated during installation, which makes it inconvenient to control the display direction of the pressure gauge 6.

[0022] In the embodiment: two fixed frames 1 are sleeved on the outside of the two auxiliary water outlet pipes 11, and two bolts 8 are movably connected to the outer walls of the two auxiliary water outlet pipes 11 respectively;

[0023] Specifically, the fixing frame 1 is fitted onto the outside of the auxiliary water outlet pipe 11, which facilitates the assembly of the testing device. The bolt 8 is movably connected to the auxiliary water outlet pipe 11 and can be used in conjunction with the fixing frame 1 to fix the fixing frame 1 onto the outside of the fire hydrant body 10, achieving a quick fixing effect.

[0024] In the embodiment: a water guiding cavity is provided inside the fixed ring 5, and the water guiding cavity is fixedly connected to the input end of the pressure gauge 6; the inside of the sleeve 4 is fixedly connected to the inside of the water guiding cavity.

[0025] Specifically, the fixed ring 5 has a water guiding cavity inside, which can be connected to the pressure gauge 6 to achieve the effect of water guiding and to facilitate pressure detection. Water is guided into the sleeve 4 and then enters the pressure gauge 6 through the water guiding cavity in the fixed ring 5.

[0026] In the embodiment: a sealing gasket is provided inside the sleeve 4, the sleeve 4 is movably sleeved on the outer wall of the main water outlet pipe 12, and the output end of the main water outlet pipe 12 is movably connected to the sealing gasket.

[0027] Specifically, a sealing gasket is provided inside the sleeve 4. The sealing gasket can seal the main water outlet pipe 12 and the sleeve 4 together, thereby achieving the effect of sealing the sleeve 4 and connecting the sleeve 4 and the main water outlet pipe 12 together.

[0028] In the embodiment: two sliding holes 9 are sleeved on the outside of the two auxiliary water outlet pipes 11;

[0029] Specifically, the sliding hole 9 is fitted on the outside of the auxiliary water outlet pipe 11, which makes it easy to fit the fixing frame 1 on the outside of the fire hydrant body 10;

[0030] Working principle: The fixing frame 1 is placed on the outside of the auxiliary water outlet pipe 11, the insertion rod 2 is inserted into the inside of the fixing frame 1, and the bolt 8 is tightened to lock the fixing frame 1 onto the outer wall of the fire hydrant body 10. At this time, the sleeve 4 is placed on the outer wall of the auxiliary water outlet pipe 11, and the water guide cavity enters the pressure gauge 6, which can realize the effect of detecting the water pressure of the fire hydrant body 10. Since the annular frame 3 and the sleeve 4 are rotatably connected together, the position of the pressure gauge 6 can be adjusted by rotating the fixing ring 5 during installation. Compared with related technologies, the water pressure detection device for building fire protection facilities provided by this utility model has the following beneficial effects: It solves the problem that the connection between the fire hydrant water pressure detection device and the fire hydrant on the market is fixed, and the entire device needs to be rotated during installation, which makes it inconvenient to control the display direction of the pressure gauge 6.
