AI Technical Summary
After long-term use, the existing flat gate valve body casting structure is prone to deformation of the gate plate and valve seat due to water flow impact, which reduces sealing performance and is also highly polluted by noise.
By setting up multiple groups of convex rings inside the inlet and outlet groove of the valve body body, combining the design of the guide groove and sound absorption groove, the wavy structure of the convex ring is used to buffer the water flow, and noise is introduced into the sound absorption groove through the guide groove. It is absorbed and finally silenced through the silence hole.
It effectively reduces the impact force of water flow on the valve body body, improves sealing performance, and significantly reduces noise pollution, extends the service life of the valve body casting structure.

Description
Technical Field
[0001] The utility model relates to the technical field of flat gate valve bodies, in particular to a flat gate valve body casting structure. Background Art
[0002] The flat gate valve is a sliding valve with a parallel gate as the closing part. The closing part can be a single gate or a double gate with a spreading mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or floating valve seat. If it is a double-disc flat gate valve, the spreading mechanism between the two gates can supplement this pressing force.
[0003] During the use of the gate valve, the pressurized water flow will produce a large impact force on the gate plate, which will not affect the gate valve in a short time. However, after long-term use, the part where the gate plate and the valve seat fit together will be deformed, which will deteriorate the sealing performance of the gate valve and reduce the service life of the gate valve. In addition, in environments near residential areas or with high requirements on volume, it is necessary to reduce the noise generated by the medium hitting the side wall of the valve body to reduce noise pollution. Therefore, it is particularly important to improve the existing valve body casting structure and design a new flat gate valve body casting structure to solve the above-mentioned technical defects and improve the practicability of the overall valve body casting structure.

[0019] Furthermore, multiple groups of convex rings 5 are distributed at equal intervals inside the water inlet groove 3 and the water outlet groove 4, and the multiple groups of convex rings 5 are designed with a wavy structure. When the valve body 1 is in use, the multiple groups of convex rings 5 cooperate with their own wavy structure design to effectively buffer the flowing water and other inflowing media, thereby reducing its impact force on the valve body 1.
