DETAILED DESCRIPTION

[0022] Example one

[0023] As Figures 1-2 shown, the utility model discloses a V-shaped gate valve, which comprises:

[0024] Support frame 2

[0025] Valve seat 6 is arranged at the bottom of support frame 2, and the valve seat 6 comprises a valve seat body 61 arranged at the bottom of support frame 2 and a V-shaped opening 62 arranged in the valve seat body 61.

[0026] Actuator 5 is arranged on support frame 2 and used to open, partially open or close V-shaped opening 62.

[0027] And motor 1 is arranged at the top of support frame 2, and motor 1 is used to drive actuator 5 to operate.

[0028] By setting the V-shaped port 62 as a fixed structure, the failure rate can be reduced.

[0029] Embodiment Two

[0030] As Figure 4 shown, the utility model provides a kind of V-shaped gate valve, compared with embodiment one, this embodiment introduces the structure of related cooperation of actuator 5 in detail.

[0031] Actuator 5 includes screw rod 51 driven by motor 1, valve stem 54 arranged at the bottom of screw rod 51, position indicator 52 sleeved at the top of valve stem 54, and valve plate 55 arranged at the bottom of valve stem 54 and matched with V-shaped port 62.

[0032] Further, the top of valve stem 54 is provided with external thread, and fixed nut 53 is matched and sleeved on the external thread, and the top of fixed nut 53 is in contact with position indicator 52.

[0033] Further, sealing ring 4 is arranged on valve stem 54, and sealing ring 4 is matched and sealed with support 2, and valve stem 54 passes through the top of support and valve seat 6 and is sealed by sealing ring 4.

[0034] Further, pressure plate 3 is arranged on valve stem 54, and pressure plate 3 is connected with the top of valve seat 6.

[0035] Embodiment Three

[0036] As Figure 3 shown, the utility model provides a kind of V-shaped gate valve, compared with embodiment two, this embodiment introduces the structure of support 2 in detail.

[0037] Support 2 includes support frame 21, and positioning plate 22 and scale plate 23 arranged on the left inner wall of support frame 21; flat plate is arranged on position indicator 52, the flat plate is connected with positioning plate 22, pointer is arranged on position indicator 52, and the pointer is directed to scale plate 23, and the position of current valve plate 55 is judged by the indication of pointer. Two partition plates are arranged in valve seat body 61, and opposite V-shaped ports 62 are formed in the two partition plates, and valve plate 55 is matched and inserted between the two partition plates.
