Description

Technical Field

[0001] This utility model relates to the field of fire protection testing technology, specifically a test connector for fire protection testing. Background Technology

[0002] The test fitting for fire protection testing is one of the key pieces of equipment used for testing and maintaining fire protection systems. It is usually installed on the piping of the fire protection system to conduct a water test before the system is put into operation to ensure that the system is working properly, and to conduct regular water flow and pressure tests on the system. In order to ensure that the end of the fire protection facility can discharge water normally and that the water pressure is within the normal standard, it is necessary to test the end of the fire protection facility through the test fitting.

[0003] Because the test connector is directly connected to the fire hose, the water pressure will be high during testing. When draining, the high-speed water flow impacts the ground and forms water mist, which can easily cause operators to slip and fall. In addition, when the valve is suddenly opened, the pressure wave of the water flow repeatedly vibrates in the pipeline, causing strong vibrations, which can lead to the loosening of the support, cracking of the weld, and fatigue failure of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a test connector for fire protection testing, in order to solve the problems of high water pressure, high-speed water flow impacting the ground and forming water mist during drainage, which can easily cause operators to slip and fall, and the pressure wave of water flow repeatedly oscillating in the pipeline when the valve is suddenly opened, causing strong vibration, resulting in loose support, cracked welds and fatigue failure of equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire testing connector, comprising a connecting pipe, one end of which is fixedly connected to a connector, and further comprising:

[0006] A valve is fixedly installed on the connecting pipe, and a pressure gauge is fixedly installed on the connecting pipe;

[0007] A bend is fixedly installed at the end of the connecting pipe away from the connector. A water outlet pipe is fixedly connected to the end of the bend away from the connecting pipe. A protective component to suppress pipe vibration is installed on the water outlet pipe.

[0008] Preferably, the bend is U-shaped and its two ends are fixedly connected to the connecting pipe and the outlet pipe, respectively.

[0009] Preferably, the connecting pipe is tapered, and its diameter gradually decreases from the connector to the bend.

[0010] Preferably, the protective component includes a fixed cylinder installed on the water outlet pipe, an installation tube fixedly installed at the bottom of the fixed cylinder, a spring fixedly connected to the inner wall of the fixed cylinder, a piston fixedly connected to the top of the spring, and the piston and the inner wall of the fixed cylinder being slidably connected.

[0011] Preferably, the inner wall of the bend is fixedly connected with several sets of inclined plates to reduce the impact force of the water flow.

[0012] Preferably, the top of the fixed cylinder is threaded with a sealing cap, and the mounting tube is fitted with a sealing ring.

[0013] Preferably, both the connecting pipe and the bend are fixedly connected to a fixing ring, and a carrying strap is installed on the fixing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a pressure gauge to detect whether the water pressure meets the standard, a bend in the pipe to reduce the impact force when the water flows out, and an inclined plate to further reduce the impact force of the water flow, thus protecting the pipe and preventing the high-speed water flow from impacting the ground and forming water mist during drainage, which could easily cause operators to slip and fall. The protective components can also prevent the pressure inside the pipe from dropping to a vacuum state when the valve is suddenly opened, which could cause the pipe to collapse, cavitate, and deform.

[0021] 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.

[0022] Please see Figure 1-4As shown, a fire testing water connector includes a connecting pipe 1, one end of which is fixedly connected to a connector 2, which is a snap-fit ​​connector adapted to conventional fire hoses currently on the market. It also includes: a valve 3, fixedly installed on the connecting pipe 1, a pressure gauge 4 fixedly installed on the connecting pipe 1, the valve 3 controlling the opening and closing of the connecting pipe 1, and the pressure gauge 4 detecting the pressure of the water flow in the connecting pipe 1; a bend 5, fixedly installed at the end of the connecting pipe 1 away from the connector 2, the end of the bend 5 away from the connecting pipe 1 fixedly connected to a water outlet pipe 6, and a protective component 7 for suppressing pipe vibration installed on the water outlet pipe 6.

[0023] It should be noted that: when connecting connector 2 to the fire hose and opening valve 3, water flows into connecting pipe 1. Pressure gauge 4 can be used to check whether the water pressure meets the standard. The bend 5 can reduce the impact force when the water is discharged, and prevent the high-speed water flow from impacting the ground and forming water mist, which can easily cause operators to slip and fall. The protective component 7 can prevent the pressure wave of the water flow from repeatedly oscillating in the pipe when valve 3 is suddenly opened, which can cause strong vibration, leading to the loosening of the support, cracking of the weld and fatigue failure of the equipment.

[0024] The bend 5 is U-shaped and its two ends are fixedly connected to the connecting pipe 1 and the outlet pipe 6 respectively; the connecting pipe 1 is tapered and its diameter gradually decreases from the connector 2 to the bend 5; the arc structure of the bend 5 is used to disperse the impact stress of the water flow, avoid the stress concentration problem of the right angle bend, and extend the service life of the pipe; the inner wall of the bend 5 is fixedly connected with several sets of inclined plates 8 to reduce the impact force of the water flow, and the inclined plates 8 can further reduce the impact force of the water flow and protect the pipe.

[0025] The protective component 7 includes a fixed cylinder 701 installed on the outlet pipe 6. An installation pipe 702 is fixedly installed at the bottom of the fixed cylinder 701. A spring 703 is fixedly connected to the inner wall of the fixed cylinder 701, and a piston 704 is fixedly connected to the top of the spring 703. The piston 704 and the inner wall of the fixed cylinder 701 are slidably connected. A sealing cap 9 is threadedly connected to the top of the fixed cylinder 701, and a sealing ring 10 is fitted on the installation pipe 702. A threaded groove is provided on the top of the fixed cylinder 701, and the sealing cap 9 can be installed and fixed to the top of the fixed cylinder 701 to seal it. When the valve 3 is suddenly opened, water flows into the fixed cylinder 701 through the connecting pipe 1. The piston 704 moves inside the fixed cylinder 701, compressing the spring 703 to store energy, converting the kinetic energy of the water flow into the potential energy of the spring, reducing the pressure peak. The spring 703 rebounds and pushes the piston 704 to reset, so that the high-pressure water flow is released slowly, avoiding instantaneous impact and providing protection for the pipeline.

[0026] Both the connecting pipe 1 and the bend pipe 5 are fixedly connected to a fixing ring, and a shoulder strap 11 is installed on the fixing ring. The two ends of the shoulder strap 11 are fixed to the fixing rings of the connecting pipe 1 and the bend pipe 5 respectively, so that the user can carry the device.

[0027] Working principle: Connect connector 2 to the fire hose, open valve 3 and water flows into connecting pipe 1. Pressure gauge 4 can be used to check whether the water pressure meets the standard. Bend 5 can reduce the impact force when the water flows out. The arc structure of bend 5 disperses the impact stress of the water flow, avoids the stress concentration problem of right angle bends, extends the service life of the pipeline, and avoids the formation of water mist when the high-speed water flow hits the ground during drainage, which can easily cause operators to slip and fall. The protective component 7 can prevent water from flowing into the fixed cylinder 701 through connecting pipe 1 when valve 3 is suddenly opened. The piston 704 moves in the fixed cylinder 701, compressing the spring 703 to store energy, converting the kinetic energy of the water flow into the potential energy of the spring, reducing the pressure peak. The spring 703 rebounds and pushes the piston 704 to reset, so that the high-pressure water flow is released slowly, avoiding instantaneous impact and providing protection for the pipeline.
