Their main function is to control combustible materials, isolate combustible materials, and eliminate ignition sources. The pressure measuring joint is a special device for measuring the pressure of the fire hydrant system. It is mainly used to accurately judge the performance of the fire hydrant system and calibrate the water column of the water gun. The pressure measuring joint mainly includes a pressure measuring pipe and a pressure gauge installed on the pressure measuring pipe.

[0003] After searching, the Chinese patent publication number CN220833967U discloses "an assembled fire hydrant pressure measuring joint, including a coaxially arranged connecting pipe, a pressure measuring pipe, a joint pipe and a drain pipe; a clamping piece for connecting to the fire hydrant outlet is arranged at one end of the connecting pipe, and a threaded annular groove is opened on the inner wall of the other end of the connecting pipe; an annular protrusion matching the annular groove of the connecting pipe and having a thread on the outer circumference is arranged at one end of the pressure measuring pipe, so that the pressure measuring pipe and the connecting pipe can be detachably connected, a pressure measuring tube is provided, and a threaded annular groove is opened on the inner wall of the other end of the pressure measuring tube; an annular protrusion matching the annular groove of the pressure measuring tube and having a thread on the outer circumference is arranged at one end of the joint pipe, so that the joint pipe and the pressure measuring tube can be detachably connected, and a threaded annular groove is opened on the inner wall of the other end of the joint pipe".

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 5 As shown, this embodiment proposes an assembled fire hydrant pressure measuring joint, including a detection tube 1, the inlet end of the detection tube 1 is fixedly connected with a pipe joint 2 that matches the thread of the pipeline to be tested, the outlet end of the detection tube 1 is fixedly connected with a water outlet pipe 3, the water outlet pipe 3 is fixedly connected with a corresponding opening and closing valve 4, and the outer side of the detection tube 1 is fixedly connected with a pressure gauge 5 for detecting the internal water pressure of the detection tube 1; both ends of the outer side of the detection tube 1 are sleeved with arc plates 6, and the two arc plates 6 are spliced ​​into a complete circular ring structure, and both ends of the two arc plates 6 are fixedly connected with clamping blocks 7, and the outer side of the detection tube 1 is provided with a positioning component 8 for positioning and fixing the clamping block 7, and the outer side of the two arc plates 6 is provided with an operating component 9 for driving the arc plates 6 to rotate by manual operation.

[0024] During installation, two arc plates 6 are sleeved on the outside of the detection tube 1, and the positioning component 8 fixes the blocks 7 at both ends of the arc plates 6, so that the arc plates 6 and the detection tube 1 remain fixed. Then the staff drives the arc plates 6 to rotate through the operating component 9, which causes the detection tube 1 to rotate, so that the pipe joint 2 can be threadedly installed with the pipe to be tested. This process is simple to operate and there is no problem that the pressure test joint is easy to slip out of the hands of the tester.

[0025] Furthermore, the positioning assembly 8 includes a holder 81, which is fixedly connected to the outer side of the detection tube 1. The holder 81 is slidably matched with the corresponding block 7. The inner side of the holder 81 is slidably connected with a slide rod 82 that passes through the side wall of the holder 81. One end of the slide rod 82 is fixedly connected with a wedge-shaped limit block 83, and the other end of the slide rod 82 is fixedly connected with a pull block 84. A receiving groove 85 that slidably matches the wedge-shaped limit block 83 is provided on the inner wall of the holder 81. A spring 86 is sleeved on the slide rod 82, one end of the spring 86 abuts against the wedge-shaped limit block 83, and the other end of the spring 86 abuts against the inner wall of the receiving groove 85.

[0026] During installation, the blocks 7 at both ends of the arc plate 6 are inserted into the corresponding clamping seats 81, so that the blocks 7 exert pressure on the wedge-shaped limit block 83 and make it slide, which makes the wedge-shaped limit block 83 completely slide into the receiving groove 85. At this time, the spring 86 is compressed to accumulate potential energy. When the block 7 and the clamping seat 81 are fully matched, the block 7 and the wedge-shaped limit block 83 are separated. At this time, the spring 86 releases the potential energy to make the wedge-shaped limit block 83 slide in the opposite direction, so that the wedge-shaped limit block 83 restricts the block 7 to prevent the block 7 from being separated from the clamping seat 81, thereby achieving the fixation of the block 7.

[0027] When disassembling, it is only necessary to pull the pull block 84 outward to make the slide rod 82 slide outward, which allows the wedge-shaped limit block 83 to completely slide into the storage groove 85, so that the wedge-shaped limit block 83 is disengaged from the card block 7 and the restriction on the card block 7 is released, so that the card block 7 can be directly taken out of the card seat 81, and the disassembly of the arc plate 6 is realized. The whole process is simple to operate and has strong practicality.

[0028] Furthermore, the operating assembly 9 includes an arc-shaped guide frame 91, which is fixedly connected to the outer side of the arc-shaped plate 6, and a plurality of slots 92 are provided on the inner wall of the arc-shaped guide frame 91, and the plurality of slots 92 are evenly distributed along the inner wall of the arc-shaped guide frame 91, and a handpiece 93 that slidably cooperates with any of the slots 92 is movably provided on the inner side of the arc-shaped guide frame 91;

[0029] Furthermore, the hand piece 93 includes a slider 931, which is slidably connected to the inner side of the arc guide frame 91. The slider 931 is an arc structure. The inner wall of the slider 931 is slidably connected to the outer wall of the arc plate 6. Both ends of the slider 931 are fixedly connected with connecting plates 932. The two connecting plates 932 are slidably connected to the same hand rod 933 at one end away from the slider 931. A stopper 935 is fixedly connected to one end of the hand rod 933. A nut 934 is threadedly connected to the other end of the hand rod 933. A corresponding thread groove is opened at one end of the hand rod 933, and the nut 934 is threadedly matched with the thread groove.

[0030] The slider 931 is slidably engaged with the slot 92 by operating the hand-held rod 933, and when the slider 931 moves to the position of one of the slots 92, the hand-held rod 933 is pulled outward to make the slider 931 slide with the slot 92, and then a rotational force is applied to the hand-held rod 933, which causes the arc guide frame 91 to rotate, and the arc plate 6 drives the detection tube 1 to rotate. When the hand-held rod 933 moves to the lowest position, the slider 931 is disengaged from the current slot 92 by applying a thrust to the hand-held rod 933, and then the slider 931 is driven to slide to the highest position and slide with the corresponding slot 92, and then a rotational force is applied to the hand-held rod 933 again, which causes the arc guide frame 91 to rotate, and also causes the detection tube 1 to continue to rotate. The whole structure is easy to operate. The staff can avoid the problem of the detection tube 1 slipping by grasping the hand-held rod 933 for operation, and can better drive the detection tube 1 to rotate and connect with the pipeline to be tested, thereby greatly improving the installation efficiency.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
