Upper end be equipped with vertical extension, the lower end of the interconnecting piece is equipped with U-shaped extension, and the U-shaped extension surrounds the valve rod
Surrounding formed U-type groove structure；
The outer ring of the butterfly plate is provided with the valve seat；The valve seat is internally provided with to match with the U-shaped extension
The reserved space of conjunction, the vertical extension are wrapped in the U-shaped extension inside the valve seat；The valve seat passes through valve
Lid is fixed on the side wall in the valve body water passage；The valve body, interconnecting piece and valve seat are equipped with the through-hole of consistency from top to bottom,
The valve rod is interspersed in the through-hole.
Preferably, valve seat and the rear valve base being connected with the preceding valve seat cooperation before the valve seat includes；The preceding valve seat
It is connected by bolt with rear valve base.
Preferably, the outer surface of the vertical extension is in smooth curved surface.
Preferably, the valve body includes upper valve body and lower valve body, and the upper valve body and lower valve body are equipped with around the valve rod
Filler；The filler bottom end is equipped with filler washer.
Preferably, the valve rod bottom end is equipped with thrust bearing.
Preferably, the interconnecting piece is fixedly connected with the interconnecting piece of the valve rod by taper pin.
Preferably, the valve rod is interference fitted by V-shaped seal ring and the valve body.
Compared with prior art, the utility model is advantageous in that vertical extension is embedded in U type extensions
Design inside valve seat has directly completely cut off valve rod and has been in direct contact with liquid, avoid the objects such as fine sand be stuck in valve rod and valve seat it
Between, lead to that valve rod rotation is dumb, even stuck phenomenon.The design of U-shaped extension so that be caught in U-shaped extension and valve seat it
Between fine sand silt can be avoided to fall into Bearing inner, caused in the U-type groove that the inertia of object falls directly into valve rod surrounding
Valve is stuck.
Description of the drawings
Fig. 1 is the explosive view of the embedded sediment prevention three-eccentric-butterfly-valve of butterfly plate in one embodiment of the utility model.
Specific implementation mode
To make the purpose of this utility model, technical solution and advantage are clearer, below will be to the technology of the utility model
Scheme is further described.
As shown in Figure 1, proposing a kind of embedded sediment prevention three-eccentric-butterfly-valve of butterfly plate, including valve rod 1, butterfly plate in the present embodiment
2, valve seat 3, valve body 4 and valve deck 5, wherein 2 back side of butterfly plate is equipped with the interconnecting piece 21 being connected with valve rod, the upper end of interconnecting piece 21
Equipped with vertical extension 22, the lower end of interconnecting piece 21 is equipped with U-shaped extension 23, and U-shaped extension 23 surrounds the surrounding shape of valve rod 1
At U-type groove structure.
The outer ring of butterfly plate 2 is provided with valve seat 3, valve seat 3 is internally provided with and U-shaped extension 23 is matched pre- leaves a blank
Between, vertical extension 22 is wrapped in U-shaped extension 23 inside valve seat 3, and valve seat 3 is fixed on the water excessively of valve body 4 by valve deck 5 and leads to
On side wall in road, valve body 4, interconnecting piece 21 and valve seat 3 are equipped with the through-hole of consistency from top to bottom, and valve rod 1 is interspersed in through-hole.
In the present embodiment, vertical extension 22 is embedded in the design inside valve seat 3 with U-shaped extension 23, directly completely cuts off
Valve rod 1 is in direct contact with liquid, is avoided the objects such as fine sand and is stuck between valve rod 1 and valve seat 3, causes valve rod 1 to rotate ineffective
Work, even stuck phenomenon.The design of U type extensions so that being caught in fine sand between U-shaped extension 23 and valve seat 3 can be along
The inertia of object is fallen directly into the U-type groove of 1 surrounding of valve rod, and silt is avoided to fall into Bearing inner, causes valve stuck.
