specific Embodiment approach 1

[0017] Specific implementation mode one: combine Figure 1-Figure 4 To illustrate this embodiment, this embodiment includes a valve cover 1, a valve body 2, a guide sleeve 3, a first sealing ring 4, a hand wheel 5, a valve plate 6, a second sealing ring 7 and fasteners 8;

[0018] The valve body 2 is provided with a water inlet 2-1 and a water outlet 2-2, the direction of the water inlet 2-1 on the valve body 2 is perpendicular to the direction of the water outlet 2-2, and the valve plate 6 is arranged in the valve body 2 The water inlet 2-1, and the first sealing ring 4 is provided between the valve plate 6 and the valve body 2, the valve cover 1 and the valve body 2 are fixed together, the handwheel 5 is connected with the valve cover through a screw rod, and the screw rod and the valve body The valve plate 6 is fixed so that the valve plate 6 can move along the direction of the water inlet 2-1 of the valve body 2, and the guide sleeve 3 and the valve cover 1 are sealed by t...

specific Embodiment approach 2

[0020] Embodiment 2: The flow area of ​​the water outlet 2-2 of the valve body 2 in this embodiment is larger than the flow area of ​​the water inlet 2-1.

[0021] Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The flow area of ​​the water outlet 2-2 of the valve body 2 in this embodiment is 23% larger than the flow area of ​​the water inlet 2-1.

[0023] Such setting increases the ability of water discharge, and ensures that the water has a certain kinetic energy to be ejected from the present invention, and also ensures that the paddy field will not be washed away due to excessive kinetic energy of the water.

[0024] Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention discloses a counter-flow axial energy dissipation valve, belongs to the technical field of valves, and aims at solving the problem that scouring is caused to a paddy field because a gatevalve or a ball valve is adopted for existing irrigation for the paddy field. The counter-flow axial energy dissipation valve comprises a valve cover, a valve body, a flow guide sleeve, a first sealing ring, a hand wheel, a valve plate and a second sealing ring, wherein a water inlet port and a water outlet port are formed in the valve body; the direction of the water inlet port in the valve bodyis vertical to the direction of the water outlet port; the valve plate is arranged at the water inlet port in the valve body, and the first sealing ring is arranged between the valve plate and the valve body; the valve cover is fixedly connected with the valve body; the hand wheel is connected with the valve cover through a screw rod, and due to the fixed connection of the screw rod and the valveplate, the valve plate is enabled to move in the direction of the water inlet port of the valve body; and the flow guide sleeve and the valve cover are sealed through the second sealing ring, and fixed together through a fastener, so that a water outlet direction is opposite to a water inlet direction. According to the counter-flow axial energy dissipation valve, the resistance of water is increased through the valve plate, so that the dynamic energy of water is reduced; and the dynamic energy of water is further reduced by enabling the water inlet direction to be opposite to the water outletdirection, so that the scouring of high-pressure water to the paddy field is avoided.

Description

technical field [0001] The invention relates to a valve, in particular to a reverse flow axial energy dissipation valve, which belongs to the technical field of valves. Background technique [0002] The irrigation of paddy fields needs to pump water from the well for irrigation. Usually, pipelines need to be used, and gate valves or ball valves are installed at the water intake end of the pipelines. Due to the high water pressure, gate valves or ball valves are used. Due to their own structural characteristics, the kinetic energy of water cannot be reduced. , causing erosion to paddy fields. Contents of the invention [0003] In order to solve the problem that the gate valve or the ball valve used in the existing paddy field irrigation will cause scour to the paddy field, the present invention provides a reverse flow axial energy dissipation valve. [0004] The technical scheme that the present invention takes for solving the problems of the technologies described above i...
