Description

Technical Field

[0001] The utility model relates to the field of sampling tube positioning components, in particular to a sampling tube positioning component of a real-time fire water supply pressure detector. Background Art

[0002] At present, in order to ensure that the water pressure of the water supply equipment can be known in real time, a real-time water pressure detector is used to detect the water pressure of the fire water supply equipment.

[0003] When using the existing real-time water pressure detector, it is necessary to connect the sampling tube and the water pipe of the fire water supply equipment, and connecting the sampling tube requires the use of a positioning component of the sampling tube;

[0004] For the sampling tube positioning component of the water pressure real-time detector, the traditional positioning component needs to first connect the control valve and the water pipe of the fire water supply equipment with threads, and then connect the sampling tube and the control valve; using this method to position the sampling tube can facilitate the disassembly and maintenance of the sampling tube or the real-time detector without interrupting the water supply in the later stage;

[0005] However, before positioning the sampling tube, a control valve needs to be installed first. The use of the control valve will undoubtedly increase the use cost of the positioning component. Moreover, when the control valve is in use, it is impossible to achieve the function of disassembling and actively sealing the water pipe. It needs to be opened and closed. There is a situation where the valve is forgotten to be opened after being closed or forgotten to be closed after being opened. Therefore, the convenience of disassembly and maintenance of the sampling tube needs to be improved.

[0006] In order to solve the above-mentioned problems, we propose a sampling tube positioning component for a fire water supply pressure real-time detector. Utility Model Content

[0009] By adopting the above technical scheme, a spring, a fixed seat, a movable part, a sealing sleeve and a water inlet groove are set. The compression and rebound of the spring can push the movable part to drive the sealing sleeve to move up and down, thereby playing the role of water cut-off and water flow, and can replace the use of the control valve; by setting a threaded tube, an outer protective shell, a movable part, a spring, a water guide groove and a fixed seat, the threaded connection between the threaded tube and the outer protective shell pushes the movable part down, so that the water guide groove and the water inlet groove correspond to each other, which is convenient for the sampling tube to sample water. At the same time, the threaded tube and the outer protective shell are separated. The spring pushes the movable part to reset, and the water inlet groove can be blocked by the sealing sleeve, which plays the role of separation, that is, water cut-off.

[0010] The utility model is further configured as follows: two connection blocks are fixedly connected to the surface of the fixing seat, and one side of the two connection blocks away from the fixing seat is fixedly connected to the outer protective shell.

[0011] The above technical solution is adopted to support the fixing seat through the setting of the connecting block.

[0012] The utility model is further configured as follows: the top of the movable part is connected with a guide tube, and the guide tube is located inside the threaded tube.

[0013] By adopting the above technical scheme, through the setting of the guide pipe, the water from the water pipe of the fire water supply equipment enters the water inlet groove and the water guide groove and then enters the guide pipe, and then enters the interior of the threaded pipe and the sampling tube through the guide pipe, so that the water pressure real-time detector connected to the top of the sampling tube can detect the real-time water pressure.

[0014] The utility model is further configured as follows: a sealing sleeve 2 is fixedly sleeved on the surface of the guide tube, and the surface of the sealing sleeve 2 is sealingly and slidably connected with the inner wall of the threaded tube.

[0015] By adopting the above technical solution, through the provision of the guide tube and the second sealing sleeve, the second sealing sleeve can be used to improve the sealing performance of the connection between the threaded tube and the guide tube.

[0016] The utility model is further configured as follows: two sides of the water guide groove correspond to two water inlet grooves respectively.

[0017] By adopting the above technical solution, through the correspondence between the water guide trough and the water inlet trough, the water in the water pipe of the fire water supply equipment enters the water inlet trough and then enters the interior of the water guide trough.

[0018] The utility model is further configured as follows: a connecting seat is fixedly connected to the bottom end of the outer protective shell, and an external thread is integrally processed on the surface of the connecting seat.

[0019] By adopting the above technical solution, the installation of the internal thread connection of the fire water supply equipment can be met through the setting of the external thread.

[0020] The utility model is further configured as follows: an internal thread groove is provided inside the connecting seat.

[0021] By adopting the above technical solution and setting the internal thread groove, the installation of the external thread connection pipe of the fire water supply equipment can be met.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model sets a threaded connection between a threaded tube and an outer protective shell, and uses the lower end of the threaded tube to push the movable part to squeeze the spring, so that the spring is compressed, so that the two sides of the water guide groove correspond to the two water inlet grooves respectively, so that the water of the fire water supply equipment can enter the sampling tube for sampling and detection. The threaded tube and the outer protective shell are separated, and the squeezed and compressed spring can push the movable part to reset, and the two water inlet grooves can be blocked by the sealing sleeve on the surface of the movable part, so that the sampling tube is separated, that is, the water is cut off;

[0024] 2. The utility model arranges a movable part and a sealing sleeve, which can realize the circulation sampling of water by the sampling tube under the downward pressure of the threaded tube, so as to facilitate the water pressure detection of the fire water supply equipment; and by separating the threaded tube and the outer casing, the movable part and the sealing sleeve can be pushed by a spring to reset and seal the two water inlet grooves. By adopting a structure that allows water to pass through when installed and cuts off when disassembled, the use of the control valve can be replaced, and the cost required for positioning the sampling tube is reduced, thereby eliminating the operation process of the control valve, avoiding the situation of forgetting to close when opened or forgetting to open when closed, and improving its convenience.

[0034] Furthermore, two connection blocks 10 are fixedly connected to the surface of the fixing seat 6 , and the two connection blocks 10 are fixedly connected to the outer protective shell 3 on one side away from the fixing seat 6 . The setting of the connection blocks 10 is used to support the fixing seat 6 .

[0035] Furthermore, the top of the movable part 4 is connected to a guide tube 11, and the guide tube 11 is located inside the threaded tube 2. Through the setting of the guide tube 11, water from the water pipe of the fire water supply equipment enters the water inlet groove 7 and the water guide groove 8 and then enters the guide tube 11, and then enters the threaded tube 2 and the sampling tube 1 through the guide tube 11, thereby facilitating the water pressure real-time detector connected to the top of the sampling tube 1 to detect the real-time water pressure.
