Description

Technical Field

[0001] This utility model belongs to the field of industrial safety protection technology, specifically relating to a stable water pressure device used in eyewash stations. Background Technology

[0002] In the production processes of petroleum and chemical enterprises, there is a risk of emergency injuries to workers' eyes, face, or clothing caused by corrosive liquids or toxic substances splashing during production. Eye injuries, in particular, can have serious consequences if not treated promptly with on-site rinsing. Eyewash stations have become essential emergency protective facilities in situations involving contact with toxic or corrosive substances such as acids and alkalis. When workers' eyes come into contact with toxic, harmful, or other corrosive chemicals, eyewash stations can provide emergency rinsing to prevent further harm.

[0003] The prior art application number is 201920520244.0, entitled "A Composite Eyewash Station with a Pressure Stabilizing Nozzle". The above patent solves the problem that the water pressure in the water supply at the usual operating site varies greatly, which causes the water spray height of the eyewash station to change accordingly, thus making the cleaning effect of the eyewash station unstable.

[0004] Because the aforementioned existing technology of a composite eyewash station with a pressure-stabilizing nozzle is connected to the water supply at the factory operation site, although the water volume can be adjusted by the pressure-stabilizing nozzle, the water pressure fluctuation in the pipeline still exists when the flow is adjusted by the pressure-stabilizing nozzle, and the water body is prone to damage to the pipeline. Under the condition that the domestic water pressure in the factory is extremely volatile, even if the nozzle is replaced, the eyewash station may easily fail.

[0005] In view of the above factors, the use of domestic water should be avoided in the daily use of the ore dressing plant. However, the water pressure of domestic water in the plant is prone to fluctuation, which may cause the eyewash station to malfunction. Therefore, a water pressure stabilizing device for eyewash stations is provided. It can generate a self-pressurizing effect and has a water storage function to prevent failure in emergency situations. It is equipped with a heat tracing structure to keep the inlet and outlet pipes warm and prevent freezing during use. Utility Model Content

[0006] The purpose of this invention is to provide a stable water pressure device for use in eyewash stations, in order to solve the problems mentioned in the background art.

[0007] The purpose of this utility model is achieved through the following technical solution: a stable water pressure device applied to an eyewash station, including an eyewash station and an inlet pipe connected to the eyewash station. The inlet pipe includes a main pipe and a branch pipe, which are arranged in parallel, and a pressure stabilizing device is provided on the branch pipe.

[0008] The water inlet pipe is equipped with a buffer device and a push plate switch. The buffer device is located 20-30 cm in front of the push plate switch.

[0009] It also includes a water outlet pipe connected to the eyewash station. The water outlet pipe includes an upper connection end and a lower connection end. The upper connection end is detachably connected to the channel opening of the eyewash station. The lower connection end is detachably connected to the positioning base. A drainage channel is provided at the lower connection end 5-10 cm away from the base. The drainage channel is connected to a pre-buried underground drainage well through a connecting pipe.

[0010] Furthermore, both the main pipeline and the branch pipeline are equipped with electromagnetic valves, and the branch pipeline is equipped with a pressure stabilizing device including a water tank and an inlet and an outlet connected to the water tank.

[0011] The water inlet of the water tank is connected to the branch pipeline via a connecting pipe;

[0012] The outlet of the water tank is connected to the inlet pipe via a connecting pipe.

[0013] Furthermore, the voltage stabilizing device is wall-mounted and positioned 1-2 meters above the location of the eyewash station;

[0014] The voltage stabilizing device is equipped with an exhaust port, which is detachably connected to an automatic exhaust valve via a DN25 pipe.

[0015] Furthermore, the buffer device includes a tee pipe connected to the water inlet pipe, and a closed buffer pipe detachably connected to the tee pipe, wherein a buffer structure is provided inside the closed buffer pipe;

[0016] The buffer structure can move up and down along the closed buffer tube.

[0017] Furthermore, the buffer structure includes a plug that contacts the closed buffer tube. The lower end of the plug is arc-shaped, and two sealing grooves are provided on the plug. Circular rubber rings are installed in the two sealing grooves.

[0018] The circular rubber ring contacts the closed buffer tube to form a sealed structure.

[0019] The plug is made of hard silicone material and has a height of 10-15 cm.

[0020] Furthermore, the buffer device is installed on the main pipeline near the solenoid valve.

[0021] Furthermore, electric heat tracing structures are installed on the main pipeline and the branch pipeline;

[0022] The drainage channel is equipped with an electric heat tracing structure in the pre-buried underground drainage well connected by the connecting pipe.

[0023] The electric heat tracing structure is an electric heat tracing tape, which is spirally wound around the pipe wall of the pre-buried underground drainage well.

[0024] The electric heat tracing structure is connected to a power junction box, which is connected to a temperature control box located on the bottom via a power cable. The temperature control box is configured with a single-chip microcomputer or PLC.

[0025] Furthermore, the pre-embedded underground drainage well is pre-installed in the support membrane shell, and a temperature sensor node is installed in the support membrane shell. The temperature sensor node is connected to the temperature control box via a connecting line.

[0026] Furthermore, the temperature control box is wirelessly connected to a control terminal, which may be a computer or a mobile phone.

[0027] A method of using a water pressure stabilizing device applied to an eyewash station includes the following steps;

[0028] The eyewash station is connected to a water inlet pipe, which includes a main pipe and branch pipes arranged in parallel, and a pressure stabilizing device is installed on the branch pipes.

[0029] When the water pressure in the main pipeline becomes insufficient, the main pipeline is cut off by a solenoid valve. At this time, the branch pipeline remains connected to the eyewash station. The water inlet pipe is connected 10cm from the top of the water tank in the horizontal direction. The eyewash station is connected to the opening at the bottom of the water tank. When the pipeline pressure is sufficient, the water tank automatically fills with water and the top air is released. When the pipeline pressure is insufficient, the eyewash station can be used to increase the pressure in the pipeline by using the siphon effect in the water tank. When there is a water outage, the water stored in the water tank is sufficient for the emergency use of the eyewash station.

[0030] The main pipeline and branch pipeline are equipped with electric heat tracing structures, and the pre-buried underground drainage wells connected by the drainage channels through connecting pipes are equipped with electric heat tracing structures.

[0031] The electric heating structure provides insulation in winter and prevents the water temperature in the eyewash station from getting too high during emergency showers. Temperature sensor nodes collect the temperature, and when the sensed water temperature exceeds 30 degrees Celsius, the water stored in the device will be automatically drained and replenished with cold water until the water temperature meets the requirements.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0033] This utility model adopts a wall-mounted structure for the water tank, which is installed 1.5 meters above the eyewash station. A 25mm hole is made in the top of the water tank, and an automatic air vent valve is connected to it via a DN25 pipe. The water inlet pipe is connected to the water tank horizontally 10cm from the top. The eyewash station is connected to the bottom of the water tank. When the pipeline pressure is sufficient, the water tank automatically fills with water and vents at the top. When the pipeline pressure is insufficient, the eyewash station can use the siphon effect in the water tank to increase the pressure in the pipeline. In the event of a water outage, the water stored in the tank is sufficient for emergency use of the eyewash station.

[0034] This invention provides a buffer structure to prevent pipeline oscillations caused by valve closure during use. A circular rubber ring contacts a closed buffer tube to form a seal. The plug is made of hard silicone and is 10-15 cm high. This structure, with the circular rubber ring contacting the closed buffer tube to form a seal, balances the pressure within the pipeline through the movement of the buffer structure within the closed buffer tube, effectively eliminating irregular oscillations.

[0035] This utility model is equipped with a heat tracing structure, which can provide heat preservation and antifreeze treatment for the water inlet and drainage pipes during use.

[0036] This utility model is equipped with a temperature controller and temperature sensor nodes, which can monitor the pipeline temperature in real time and facilitate adjustment through a heat tracing structure.

[0037] This invention can generate a self-pressurizing effect and has a water storage function, which can prevent failure in emergency situations. Attached Figure Description
