Description

Technical Field

[0001] The utility model relates to the field of quick purge adapters, in particular to a quick purge adapter for a fire hose. Background Art

[0002] After using the fire hose for fire fighting and rescue, the water in the fire hose needs to be drained out of the fire hose first, and then the fire hose can be rolled up and recycled. The common practice now is to first remove the fire hose, and then manually lift the hose and slowly walk from one end to the other end, using gravity to drain the water in the hose, which is time-consuming and laborious; another method is to remove the hose joint from the fire truck or fire hydrant, and then connect it to a purge machine to use compressed air to quickly drain the water. The disadvantage is that the purge machine is generally large and heavy, and it is not convenient to carry. In addition, it is also inconvenient to disassemble the hose joint back and forth. In view of the above shortcomings, the present invention adopts an adapter between the water outlet valve of the fire truck or fire hydrant and the fire hose joint, and the compressed air enters through the adapter The fire hose can be quickly blown out of the residual water in the hose, so that one or more hoses connected to the fire truck or fire hydrant can be quickly purged without removing the hose joint, which saves time and effort, and greatly reduces the finishing work of fire rescue personnel after fire extinguishing and rescue. However, most of the existing quick purge adapters are required to manually discharge the residual water in the hose when the fire hose is recycled after use. The existing quick purge adapter needs to be disassembled and moved when used, which leads to time-consuming and laborious problems. The utility model provides a device that is easy to install, does not need to be disassembled and assembled back and forth when used, is convenient and fast, has a beautiful appearance, and has various connection forms, and can adapt to various types of fire hose joints.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1 The utility model provides an embodiment: a fire hose quick purge adapter, including an adapter body 1, a sealing ring body 2, a one-way valve 3, a quick connector 4, and a sealing ring body 5. The adapter body 1 is divided into a sealing ring body 2; a one-way valve 3 is fixedly installed on the upper end of the sealing ring body 2; a quick connector 4 is fixedly connected to the upper end of the one-way valve 3; a sealing ring body 5 is arranged on the side end of the adapter body 1. After the use of the water hose, there is no need to remove the water hose joint. It can be installed on the purge machine for purge, and the purge work can be completed directly, which saves time and effort; it can be installed on the water outlet 14 of the fire truck and the water outlet 14 of the fire hydrant for fixed use, or a blind cover can be added to one end of the adapter for mobile use with an air breathing apparatus cylinder; there are various connection methods, which can be applicable to various fire hose joint connection forms, with a simple structure, safety and reliability.

[0024] See also Figure 2-4In this embodiment, a one-way valve 3 is fixedly installed on the upper end of the adapter body 1; a sealing ring body 2 is provided on the upper end of the one-way valve 3, and a quick connector 4 is fixedly installed on the upper end of the sealing ring body 2; a sealing ring body 5 is fixedly installed on the side end of the adapter body 1, and a sealing ring groove 6 is provided inside the adapter body 1; a threaded hole 9 is provided on the upper end of the adapter body 1, and a sealing ring groove 10 is provided on the side end of the threaded hole 9; a water outlet valve 11 is connected to the side end of the adapter body 1, and a first water hose joint 12 is rotatably connected to the side end of the adapter body 1; a second water hose joint 13 is installed on the side end of the first water hose joint 12, and a water outlet 14 is provided on the side end of the water outlet valve 11; a water hose body 16 is connected to the side end of the second water hose joint 13.

[0025] When using it, first, there is a threaded hole 9 in the middle of the cylindrical surface of the adapter body 1, and a sealing ring groove 10 is provided at the end of the threaded hole 9. First, put the sealing ring body 2 into the sealing ring groove 10, then screw the one-way valve 3 into the threaded hole 9, and then screw the quick connector 4 into the one-way valve 3, and finally put the sealing ring body 5 into the sealing ring groove 6, and the installation of the adapter is completed. The adapter has three usage forms: one is to install it on a fire truck; the second is to install it on a fire hydrant; the third is to add a blind cover to one end of the connector and match it with the air respirator cylinder. The adapter can be used in a mobile form. There are multiple connection methods. When threaded connection is adopted, there are three structural forms, wherein the first is that the water inlet and outlet 14 are both in the form of internal threads, the second is that one end of the water inlet and outlet 14 is in the form of internal threads and the other end is in the form of external threads, and the third is that the water inlet and outlet 14 are both in the form of external threads.
