Detailed Description

The embodiments of the invention will be further described with reference to the accompanying drawings in which:

as shown in the figures, the U-shaped valve groove conveying system comprises at least one gate valve 1 and U-shaped grooves 2 fixedly arranged on the front side and the rear side of each gate valve 1, each gate valve 1 comprises a valve seat 3, a valve rod 4, a valve body 5, a valve plate 6 and an operating mechanism 7, the valve seats 3 and the valve bodies 5 are in U shapes with hollow middles and closed upper ends, and the valve plates 6 are in solid U shapes; the technical scheme has the using working conditions that ores after being mined in metallurgy, ore smelting, mineral fertilizers and the like are ground into powder and then are added with various extracting solutions and slurry after reacting liquid, an open U-shaped groove is adopted for conveying, the purpose of applying the U-shaped groove is to facilitate the ore slurry to deposit or harden a layer of adhesive objects on the groove wall or the pipe wall after being conveyed for a long time, the opening is convenient for cleaning by using devices, and the U-shaped gate valve is also convenient for cleaning; and compared with a round valve with the same caliber, the U-shaped valve has the advantages of less material consumption, lower cost and investment saving.

The U type gate valve is installed on the main tank and divides the groove, divides the liquid in groove to get into in the big jar of reaction, flows out from another minute groove again after carrying out abundant stirring reaction, advances one and all sets up the valve and carries out the switch, is convenient for clear up and maintain the big jar of reaction after operation a period, and such big jar of reaction has tens in one set of device, installs the U type gate valve on main tank and minute groove and needs a project of a hundred, can save a large amount of investments.

The valve body 5 outside is equipped with flange face one 8, the terminal surface in U type groove 2 is equipped with flange face two 9, flange face one 8 passes through bolt fixed connection with flange face two 9 at both ends around with, and U type gate valve does not need the mechanical tubes at both ends to connect, can directly be connected with U type groove, and the clearance of being convenient for saves two mechanical tubes, reduce cost.

Be equipped with the elastic thrust mechanism who provides the required thrust of valve plate 6 and the sealed cooperation of disk seat 3 between valve plate 6 and the valve body 5, elastic thrust mechanism includes vertical installation and is in on the valve body 5 and correspond first elastic component and the horizontal installation of 6 both sides vertical limit of valve plate just correspond the second elastic component 11 of 6 upper edges of valve plate, adopt activity adjustable connection between valve body 5 and the disk seat 3, the C type bottom position fixed mounting of 5 inner chambers of valve body has the third elastic component 12 that corresponds with 6 bottoms of valve plate, the valve body 5 left and right sides is equipped with the confession respectively the mounting groove 13 that first elastic component settled, and an elastic thrust is applyed to the valve plate jointly to first elastic component and second elastic component among this technical scheme, makes it can keep sealed cooperation with the disk seat always when the closed condition.

The third elastic member has the same structure as the second elastic member.

The valve seat 3 and the valve body 5 are movably connected in an adjustable mode through a first fixing bolt 14 and a first adjusting screw 15, an O-shaped elastic sealing piece 16 is arranged between the valve seat 3 and the valve body for sealing, the cross section of the valve seat 3 is L-shaped, the movable valve seat in the technical scheme is closed U-shaped, the local cross section of the movable valve seat is L-shaped, and sealing surfaces are distributed on the periphery of the whole U-shaped; due to the special shape, if the valve seat is not a movable valve seat, the valve seat and the valve body are integrated, so that the valve seat is inconvenient to process, the processing flatness is not ensured, and the sealing surface is not convenient to grind; the movable valve seat is convenient to be processed independently, and the sealing surface is convenient to grind a sealing plane on a grinding machine; when the valve plate is assembled, the valve plate is completely attached to the sealing flat plate of the valve plate conveniently through the adjustment of the fixing bolt and the adjusting screw; the movable adjustable valve seat, the special elastic thrust structure and the installation mode in the technical scheme ensure that the large-caliber U-shaped valve is suitable for the key technical guarantee under severe conditions.

The valve seat is a large U-shaped sealing frame, so that local deformation is easy to occur after processing is finished, the mounting positions of the sealing surface of the valve seat and the sealing surface of the valve plate are adjusted through adjusting screws and fixing bolts, the valve seat and the valve plate are completely attached, the influence of factors such as valve body manufacturing errors and the deformation of the valve seat is avoided, and effective sealing is formed when an elastic thrust mechanism on the back of the valve plate applies pretightening force.

The first elastic component in the technical scheme has two embodiments:
