[0002] A wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction and alarms at a specified flow rate. Normally, the water pressure before and after the valve disc of the wet alarm valve is equal (water passes through the water pressure balancing hole in the guide pipe to maintain the water pressure balance before and after the valve disc).

[0003] Existing patent: CN215059759U, discloses a wet alarm valve with a protective device, including: an alarm valve body, the surface of the alarm valve body is slidably connected with a protective device. The wet alarm valve with a protective device is fixed to the top of the alarm valve body by fixing a fixed block, fitting the moving block with the fixed block, moving the fixed block and the moving block downward to insert the positioning block into the positioning groove, positioning the fixed block and the moving block, sliding the shell along the top of the fixed block and the moving block until the card block is inserted into the card slot, the guide rod is inserted into the guide slot, and the position of the shell is limited by the limit block, so that the position of the fixed block, the moving block and the shell can be fixed. The alarm valve body is protected by the fixed block, the moving block and the shell, which effectively prevents foreign objects from having hard contact with the alarm valve body, and achieves the effect of protecting the alarm valve.

[0004] The above patent or existing wet alarm valve has the following problems:

[0005] The pressure gauges of existing wet alarm valves are directly exposed to the air and protrude from the valve body. However, the pressure gauges have poor protection and are easily damaged when hit. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wet alarm valve with a protective structure, including a valve body component, a pressure gauge is arranged on the valve body component, a delay device connected to the valve body component, an alarm is arranged on the delay device, a pressure gauge protection structure is arranged on the pressure gauge, the pressure gauge protection structure includes a connecting sleeve, the connecting sleeve is arranged on the pressure gauge, a fixed sleeve connected to the connecting sleeve, a rotating sleeve is arranged on the surface of the fixed sleeve, a mounting plate is arranged on the top of the connecting sleeve, a plug-in plug-in connected to the mounting plate, the plug-in is arranged at the bottom of the protective sleeve, plug-ins are arranged on the left and right ends of the bottom of the protective sleeve, a fixing box is arranged at the bottom of the mounting plate, a spring is assembled inside the fixing box, and a block connected to the spring.

[0008] Preferably, the fixing sleeve is conical in a natural state without being subjected to force.

[0009] Preferably, the card block is in a "T" shape, and two plug-ins are provided at a point on the bottom of the protective cover. After the two plug-ins are plugged into the mounting plate, they are located at the front and rear ends of the card block.

[0010] Preferably, the fixing box is provided with stoppers inside, and the stoppers are respectively located at the front and rear ends inside the fixing box.

[0011] Preferably, an observation port is provided in the middle of the surface of the protective cover adjacent to the pressure gauge pointer.

[0012] Beneficial effects of the utility model:

[0013] The utility model is provided with a pressure gauge protection structure. The pressure gauge needs to be installed and fixed, and it is sleeved on the surface of the pressure gauge. Then, the clamping block is pressed to make it slide into the fixing box. Then, the bottom of the protective cover is fitted with the top surface of the mounting plate, so that the plug-in is plugged into the mounting plate and penetrates the mounting plate to protrude from the bottom of the mounting plate. Under the action of the spring, the clamping block slides out of the fixing box and positions the plug-in, thereby fixing the protective cover on the surface of the mounting plate. Since the protective cover is sleeved on the surface of the pressure gauge, the pressure gauge can be protected by the protective cover when it is collided, avoiding direct collision with the pressure gauge, thereby protecting the pressure gauge.

DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 and Figure 2 The utility model provides a wet alarm valve with a protective structure, comprising a valve body component 1, a pressure gauge 2 is arranged on the valve body component 1, a delay device 3 connected to the valve body component 1, an alarm 4 is arranged on the delay device 3, and a pressure gauge protective structure 5 is arranged on the pressure gauge 2;

[0023] When a fire occurs, the closed sprinkler sprays water. Since the water pressure balancing hole has no time to replenish water, the water pressure above the alarm valve drops. At this time, the water pressure in front of the valve disc is greater than the water pressure behind the valve disc, so the valve disc opens to supply water to the riser and pipeline network. At the same time, water flows along the annular groove of the alarm valve into the delay device, pressure switch, hydraulic alarm and other facilities, sending out a fire alarm signal and starting the fire pump.

[0024] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The utility model provides a wet alarm valve with a protective structure. The pressure gauge protective structure 5 includes a connecting sleeve 51, which is sleeved on the pressure gauge 2, and a fixing sleeve 52 integrally formed with the connecting sleeve 51. When the connecting sleeve 51 is sleeved on the pressure gauge 2, the fixing sleeve 52 is sleeved on the pressure gauge 2 together. The fixing sleeve 52 is conical in a natural state without force, and a rotating sleeve 53 threadedly connected to the fixing sleeve 52 is provided on the surface of the fixing sleeve 52;

[0025] The top of the connecting sleeve 51 is integrally formed with a mounting plate 54. When the connecting sleeve 51 is mounted on the pressure gauge 2, the pressure gauge 2 will penetrate the middle of the mounting plate 54. The plug-in 55 plugged into the mounting plate 54 is integrally formed at the bottom of the protective sleeve 56. The plug-in 55 is provided at both left and right ends of the bottom of the protective sleeve 56. Two plug-ins 55 are provided at one end, which are respectively located at the front and rear ends of the protective sleeve 56.

[0026] A fixing box 57 is integrally formed at the bottom of the mounting plate 54. A spring 58 is installed inside the fixing box 57. A block 59 connected to the spring 58 is in a "T" shape. The block 59 is horizontally slidably connected to the fixing box 57. Two stoppers 510 are integrally formed at the front and rear ends of the fixing box 57. The stoppers 510 are respectively located at the front and rear ends of the fixing box 57 to limit the block 59 to prevent the block 59 from popping out. After the two plug-ins 55 are plugged into the mounting plate 54, they are located at the front and rear ends of the block 59, which improves the fixing effect of the protective cover 56. An observation port is provided in the middle of the surface of the protective cover 56 adjacent to the pointer of the pressure gauge 2, so that the staff can observe the pressure gauge 2.

[0027] The pressure gauge 2 needs to be installed and fixed, and it is put on the surface of the pressure gauge 2, and then the block 59 is pressed to make it slide along the inner wall of the fixing box 57. At this time, the spring 58 is compressed to generate elastic force, and then the block 59 will shrink to the inside of the fixing box 57, and then the bottom of the protective cover 56 will fit with the top surface of the mounting plate 54. At this time, the plug-in 55 will be inserted into the inside of the mounting plate 54, and penetrate the mounting plate 54 to protrude from the bottom of the mounting plate 54. Release the block 59. Under the action of the spring 58, the block 59 slides out of the fixing box 57, and the plug-in 55 is positioned, so that the protective cover 56 is fixed to the surface of the mounting plate 54. Since the protective cover 56 is put on the surface of the pressure gauge 2, the pressure gauge 2 can be protected by the protective cover 56 when it is hit, avoiding direct collision with the pressure gauge 2, so as to protect the pressure gauge 2.
