Description
Technical Field
[0001] The utility model belongs to the technical field of valves, in particular to a valve for water conservancy projects. Background Art
[0002] Water conservancy projects are critical infrastructure used to manage and distribute water resources to meet flood control, irrigation and water supply needs.
[0003] In water conservancy projects, valves are key components for controlling water flow. However, existing valves often lack filtering and impurity removal functions. Although some valves are equipped with filter screens, the accumulation of filter residues on the filter screens over a long period of use may cause valve blockage and affect its normal operation. In addition, impurities may also adhere to the inner wall of the valve. Long-term accumulation will reduce the flow range of water flow and reduce water delivery efficiency. Utility Model Content
[0004] The utility model aims to provide a valve for water conservancy projects, which can filter water at the valve and facilitate the replacement of the filter screen.
[0005] The hydraulic engineering valve comprises a first valve body, on which a first through hole is provided, which is connected front to back, a spherical closing member capable of opening and closing the first through hole is installed in the first through hole, a second through hole is provided, which is connected left to right, a filter member for filtering is installed in the second through hole, the filter member is in a circular tube structure and is in the same direction as the second through hole, and a filter screen is fixed in the filter member;
[0006] A filter replacement port communicating with the inside and outside is provided on the first valve body at the right end corresponding to the second through hole, and a first sealing door capable of opening and closing the filter replacement port is installed at the filter replacement port;

[0008] When the spherical closing piece is rotated until the second through hole is connected to the first through hole, the valve is opened, the front end of the first through hole is the water inlet, and when water flows into the first through hole, it passes through the second through hole and is filtered at the filter screen of the filter component installed in the second through hole. At this time, the second residue outlet is located on one side of the water inlet, and the filtered residue passes through the second residue outlet and the connecting hole in turn to reach the first residue outlet to avoid clogging of the filter screen; the second through hole of the spherical closing piece is rotated so that it is not connected to the first through hole, and the valve is closed. The spherical closing piece is rotated until the second through hole is horizontally aligned with the filter screen replacement port, and the first sealing door is opened. The filter component in the second through hole can be taken out for replacement, and the filter residue accumulated at the filter screen replacement port can be cleaned by opening the second sealing door; the filter component can not only filter the water entering the valve at the water inlet, but also the filter component is easy to replace.
[0009] Furthermore, the aperture of the first through hole is smaller than that of the second through hole, and the filter component and the inner side wall of the second through hole are fitted to each other.
[0010] The aperture of the first through hole is smaller than that of the second through hole, and the filter component in the spherical closing member only needs to be placed in the second through hole to complete the installation, which makes installation and replacement convenient.
[0011] Furthermore, a storage pipe is connected to the first slag outlet.
[0012] A storage pipe is connected at the first slag outlet, and a second sealing door is installed at the lower end of the storage pipe. By connecting the storage pipe, the filter residue is stored at the bottom of the storage pipe. After the valve is closed, the filter residue at the bottom of the storage pipe is cleaned by opening the second sealing door. The storage pipe has a large storage capacity for the filter residue, thereby extending the replacement cycle of the filter component.
[0013] Furthermore, a valve stem is vertically provided on the top of the spherical closing member to drive the spherical closing member to rotate, and a corresponding valve stem mounting opening is provided on the top of the first valve body that communicates with the inside and outside of the valve stem, and the upper end of the valve stem is located above the valve stem mounting opening after passing through the valve stem mounting opening.
[0014] The upper end of the valve stem is located above the valve stem mounting opening. The spherical closing member is driven to rotate by rotating the valve stem, thereby facilitating opening and closing of the valve.
[0015] Furthermore, a first sealing member is installed on the valve stem in the valve stem mounting opening, and a hand wheel is installed on the top of the valve stem.
[0016] The first seal prevents water leakage, and the hand wheel makes it easy to turn the valve stem.
[0017] Furthermore, a water inlet is provided on the first valve body at the front end of the first through hole, an assembly port is provided on the first valve body at the rear end of the first through hole, a second valve body is installed at the assembly port, and a water outlet is provided on the second valve body which is connected front to back.
[0018] The water inlet is used to connect the water inlet pipe to facilitate water to enter the first through hole. The assembly port is used to connect the water outlet pipe. Water enters the first channel from the water inlet for filtration, and then flows out from the water outlet of the second valve body after passing through the assembly port at the rear end of the first channel. The second valve body facilitates the installation of the water outlet pipe at the water outlet end.
[0019] Furthermore, a second sealing member is provided between the water outlet and the assembly port.
[0020] The second sealing member can prevent water leakage at the connection between the second valve body and the first valve body.
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] When the spherical closing piece is rotated until the second through hole is connected to the first through hole, the valve is opened and filtering is carried out at the filter. At this time, the second residue outlet is located on the side of the water inlet, and the filtered residue passes through the second residue outlet and the connecting hole in turn to reach the first residue outlet to avoid clogging of the filter. The second through hole of the spherical closing piece is rotated so that it is not connected to the first through hole, the valve is closed, and the spherical closing piece is rotated until the second through hole is horizontally aligned with the filter replacement port. The first sealing door is opened, the filter component in the second through hole can be taken out for replacement, and the filter residue accumulated at the filter replacement port can be cleaned by opening the second sealing door. The filter component can not only filter the water entering the valve at the water inlet, but also the filter component is easy to replace. BRIEF DESCRIPTION OF THE DRAWINGS
