Description

Automatic Filter Shell Vegetable Valve

technical field

The utility model relates to an automatic valve for filtering shell vegetables.

Background technique

The technical water supply of the generator set is a very important cooling medium for the unit. The technical water supply is often taken through the draft pipe of the unit, and then pressurized by the technical water supply pump and then enters the cooling water system. Since the technical water supply is taken from natural water bodies, there are many impurities in the water quality. An automatic filter is added after the water pump to filter impurities. At present, the principle of automatic filter commonly used in power plants is that water flows through the cartridge type automatic filter element. After the water flows through, the impurities remain inside the filter element. After the system detects that the pressure difference is high, it will open the drain valve to flush the impurities in the filter element. Since the upper and lower reservoirs of Langyashan Hydropower Station are all natural reservoirs, the reservoirs are rich in organisms, especially the production of shell vegetables. Especially in summer and autumn, a large number of shell vegetables die and enter the technical water supply system with the water flow. Due to the structural problems of the automatic filter, the diameter of the internal filter element Small, the shell vegetables are easy to get stuck inside the filter element, and the backwash cannot be completely cleaned, which gradually leads to the blockage of the filter element, and even causes the high pressure difference of the technical water supply pump to switch the technical water supply pump. In order to ensure the smooth operation of the unit, the filter element needs to be replaced frequently Cleaning greatly increases the workload.

In order to solve the above problems, the technical solution adopted by the utility model is: an automatic valve for filtering shell vegetables, including a water inlet pipe, a first water outlet pipe, a second water outlet pipe, a shell vegetable storage box, a filter screen and a valve. One end of the water inlet pipe, one end of the first water outlet pipe and one end of the second water outlet pipe communicate with each other to form a connecting valve, the filter screen is arranged in the first water outlet pipe, and the vegetable storage box is provided with a vegetable inlet and a The sewage outlet, the vegetable inlet is connected to the other end of the second water outlet pipe, the valve is arranged at the sewage outlet of the shell vegetable storage tank, the other end of the water inlet pipe is provided with a first connecting flange, the first The other end of the water outlet is provided with a second connecting flange. When using this application, the valve is closed first, and the water mixed with shell vegetables enters from the water inlet. Since the valve is closed, the water cannot be discharged through the sewage outlet, but can only be discharged through the first water outlet pipe. When the water passes through the filter screen, it is filtered out. For the shell vegetables in the water, due to the high water pressure of the water inlet pipe, the shell vegetables cannot be discharged from the water inlet pipe, so the shell vegetables are collected in the shell vegetable storage box. When there are more shell vegetables collected in the shell vegetable storage box, open the valve , the water flushes the shell vegetables from the sewage outlet to realize the cleaning of the shell vegetable storage box.

This application sets a pressure equalizing pipe. When the water inlet pipe and the first water outlet pipe are flooded, the water pressure in the two can be equalized by opening the pressure difference switch. The difference switch and the sewage outlet can have part of the water flow from the first water outlet pipe to the second water outlet pipe through the pressure equalizing pipe, thereby flushing the filter screen.

As a further improvement of the utility model, the water inlet pipe and the first water outlet pipe are located on the same horizontal line, the second water outlet pipe is located below the water inlet pipe, and the vegetable inlet is set on the upper part of the shell vegetable storage box , the drain outlet is set at the bottom of the shell vegetable storage box. In the present application, the second water outlet pipe is arranged at the bottom, and the gravity of the water and the shell vegetables is fully utilized to make the shell vegetables sink naturally into the shell vegetable storage tank, so as to prevent the shell vegetables from blocking the water inlet pipe.

As a further improvement of the utility model, the valve is an electric valve. This application adopts an electric valve to facilitate the opening and closing of the sewage outlet, saving time and effort.

As a further improvement of the utility model, it is characterized in that: the end of the second outlet pipe adjacent to the shell vegetable storage box is provided with a third connecting flange, and the vegetable inlet of the shell vegetable storage box is provided with a The fourth flange, the fourth flange and the third flange are connected through bolts and nuts. In this application, a flange is used to connect the shell vegetable storage box and the second water outlet pipe to facilitate the connection between the two.

As a further improvement of the utility model, a gasket is provided between the third flange and the fourth flange. The application adopts a gasket to prevent water leakage and improve the sealing performance of the application.

In summary, the beneficial effects of the utility model are: the application filters out larger objects such as shell vegetables in the water through the filter screen, without installing a filter element, reducing the time for installing, disassembling and rinsing the filter element, and improving the efficiency of the application. usage efficiency.
