Description

Technical Field

[0001] The utility model relates to a waste discharge system, in particular to a submerged discharge valve system for discharging water from a reservoir. Background Art

[0002] A stilling basin is an energy dissipation facility that creates an underflow hydraulic jump downstream of a discharge structure. It can quickly transform a rapid downstream flow into a slow one, typically eliminating 40% to 70% of the kinetic energy of the downstream water flow and shortening the length of the apron, making it an effective and economical energy dissipation facility. Existing stilling basin systems have a stilling valve at the bottom of the basin, making it extremely difficult to repair and maintain. This requires the installation of a service valve in front of the waste pipe, further increasing costs. When installed at the bottom of the stilling basin, the stilling valve is constantly impacted by water and is easily damaged. Therefore, it needs to be cast in place during infrastructure construction, making it difficult to replace. Utility Model Content

[0006] As a further improvement of the present design, the cross section of the energy dissipation pier is trapezoidal, and the side of the energy dissipation pier connected to the stilling pool serves as the bottom.

[0007] As a further improvement of the present design, the stilling basin and the pipe fixing seat are integrally cast concrete structures.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention. Example

[0019] See Figure 1 and Figure 3This embodiment provides a submerged discharge valve system for releasing water from a reservoir, comprising a piston valve 2, a waste discharge bend 6 arranged at the outlet of the piston valve 2, and an energy dissipation pool 9 arranged at the outlet of the waste discharge bend 6. A valve fixing seat 1 is provided outside the opening of the energy dissipation pool 9, and the piston valve 2 is provided on the valve fixing seat 1. The waste discharge bend 6 is L-shaped and its outlet is downward. A pipe fixing seat 5 is provided at the opening of the energy dissipation pool 9, and the pipe fixing seat 5 is connected to the corner of the waste discharge bend 6. The outlet of the waste discharge bend 6 is downward toward the bottom center of the energy dissipation pool 9. An energy dissipation pier 7 is provided on the side of the energy dissipation pool 9. The energy dissipation pier 7 extends toward the center of the energy dissipation pool 9, and the outlet of the waste discharge bend 6 extends to below the tip of the energy dissipation pier 7.

[0020] The piston valve 2 arranged outside the stilling pool 9 cooperates with the stilling pool 9 to achieve energy dissipation, without clogging and without water flow impacting the valve body to cause damage to the valve body, making maintenance and replacement more convenient.

[0021] See Figure 1 To improve the stability of the waste discharge elbow 6 and prevent the reaction force of the impact force from impacting the waste discharge elbow 6, a tie rod 8 is installed on the side wall of the energy dissipation pool 9, connecting to the outlet of the waste discharge elbow 6. To reduce the impact of water flow on the tie rod 8, the tie rod 8 passes through the energy dissipation pier 7, that is, the connection point between the tie rod 8 and the energy dissipation pool 9 is located inside the energy dissipation pier 7.

[0022] See Figure 1 In order to improve the stability of the energy dissipation pier 7, the cross section of the energy dissipation pier 7 is trapezoidal, and the side of the energy dissipation pier 7 connected to the stilling pool 9 is the bottom.

[0023] See Figure 1 In order to facilitate construction, the energy dissipation pool 9 and the pipe fixing seat 5 are an integrally cast concrete structure.

[0024] See Figure 1 In order to further offset the impact of the centrifugal force of the fluid in the waste discharge elbow 6 on the waste discharge elbow 6, the bend of the waste discharge elbow 6 is completely wrapped in the pipe fixing seat 5.

[0025] See Figure 1 In order to improve the durability of the energy dissipation pool 9, the inner wall of the energy dissipation pool 9 and the outer wall of the energy dissipation pier 7 are both bonded with stainless steel plates.

[0026] See Figure 2Two layers of baffles 4 are installed within the waste elbow 6. These baffles 4 extend along the direction of the waste elbow 6 and are arranged parallel to each other. The baffles 4 extend through at least the bend of the waste elbow 6, with the radius of one baffle 4 at the bend being smaller than the radius of the other baffle 4 at the bend. The baffles 4 divert the fluid flow, reducing the impact of centrifugal force on the bend of the waste elbow 6 and improving the service life of the waste elbow 6.

[0027] See Figure 1 In order to reduce the noise and vibration in the exhaust elbow 6, an upwardly extending air supply pipe 3 is provided at the top of the inlet of the exhaust elbow 6.
