Abstract
The utility model relates to a single wedge disc ceramic rotary material feeding valve and belongs to the material feeding valve category. A rocker arm is arranged on a lower valve body of the single wedge disc ceramic rotary material feeding valve, a pre-tight spring is arranged in the rocker arm, a wedge disc is arranged above the rocker arm, a wedge disc ceramic sealing ring is arranged in the wedge disc, the rocker arm supports both the wedge disc and the wedge disc ceramic sealing ring, a valve seat is arranged in an upper valve body, a valve seat ceramic sealing ring is arranged on the valve seat, and the wedge disc ceramic sealing ring is tightly attached to the upper valve body and the valve seat ceramic sealing ring. The single wedge disc ceramic rotary material feeding valve has the advantages that the wedge disc ceramic sealing ring is tightly attached to the upper valve body and the valve seat ceramic sealing ring under the support of the pre-tight spring, forced rigidity sealing between the wedge disc ceramic sealing ring and the valve seat ceramic sealing ring is achieved, anti-abrasion is strong and service life is long.
Description
Technical field
The utility model belongs to a kind of valve, particularly a kind of single disc pottery rotating feeding valve that is widely used in the fields such as electric power, oil, chemical industry, metallurgy, mine, papermaking, food, garbage disposal.
Background technology
Storehouse pump inlet valve in air-transport system is selected double-flashboard gate valve usually at present, double-flashboard gate valve is a kind of of valve, it comprises valve body, valve seat, flashboard and transmission device, valve body are provided with import and outlet, are provided with ring-shaped valve seats in the valve pocket inlet and outlet of valve body, be provided with flashboard in the valve pocket, transmission device is connected with flashboard.Flashboard is opened, and closes the connection that can control import and export and closes.When flashboard rose unlatching, medium flowed into from inflow point, flowed out from the exit, consisted of a valve circulation.When flashboard descended closure, medium disconnected in the exit, consists of a valve closing.By the lifting flashboard, flashboard is opened, closure namely can realize the circulation of medium or blocks.There is following defective in it:
1, when the flashboard rising, during the medium circulation, medium constantly washes away flashboard, valve seat, especially has the medium of particle, and flashboard, valve seat seriously wash away and wear and tear, and the flashboard, the valve seat that consist of sealing surface in the present gate valve generally are the hard alloy making, not hard alloy not wear-resisting, withstanding corrosion not, not erosion resistant performance, so that medium wash away and corrosion causes flashboard and valve seat very easily damaged, thereby the sealing property of losing.
2, when medium is particle, valve is after operation a period of time, body cavity accumulates a part of medium, causing flashboard can not open when rising unlatching puts in place, descend when closing to such an extent as to wash away flashboard or flashboard, can not close and put in place, wash away sealing pair to such an extent as to sealing pair can not fit tightly, so that valve shortens service life, must often change.
The damage of flashboard and valve seat causes valve seal failed or poorly sealed, has lost the performance of valve, must change sealing member or valve to guarantee the normal operation of valve, affects the service life of valve.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, a kind of single disc pottery rotating feeding valve is provided, it is by installing the ceramic seal circle at flashboard and valve base chamber, and by the rocking arm support flashboard with preloading spring, make flashboard ceramic seal circle be close to upper valve body and valve seat ceramic seal circle, realize forcing hard sealing, valve integral body is wear-resistant, and the life-span is long.
The purpose of this utility model is achieved through the following technical solutions: a kind of single disc pottery rotating feeding valve, and it comprises upper valve body and lower valve body; Said upper valve body is connected by fastener with lower valve body, and valve rod is installed in the said upper valve body, and valve rod is fixed with upper valve body by packing gland and compression gland, the upper end connection for transmission bar of valve rod, drive link connection actuating unit; It is characterized in that: it also comprises rocking arm, preloading spring, flashboard, flashboard ceramic seal circle, valve seat and valve seat ceramic seal circle; Said lower valve body is funnel type, and rocking arm is installed in the lower valve body, and the bottom of valve rod is connected with the fixed end of rocking arm; preloading spring is installed in the movable end of rocking arm; flashboard is installed in the top of rocking arm, and flashboard ceramic seal circle is installed in the flashboard, and rocking arm supports flashboard, flashboard ceramic seal circle; Valve seat is installed in the said upper valve body, valve seat ceramic seal circle is installed on the valve seat, flashboard ceramic seal circle is close to upper valve body and valve seat ceramic seal circle.
Advantage of the present utility model and beneficial effect are:
1, preloading spring is installed in rocking arm, valve plate, flashboard ceramic seal circle are supported, make the flashboard ceramic seal circle of installing on the flashboard be close to the valve seat ceramic seal circle of installing on upper valve body and the upper valve body, flashboard ceramic seal circle and valve seat ceramic seal circle realize forcing hard sealing.
2, valve seat ceramic seal circle and flashboard ceramic seal circle are wear-resistant ceramic material, and wear-resistant, the life-span is long.
3, drive link is outside at valve, effectively prevents medium washing away drive link.
4, lower valve body is infundibulate, effectively strengthens the valve body body cavity, not dust stratification, not bite.

Wherein: 1-upper valve body, valve body under the 2-, 3-fastener, 4-valve rod, 5-packing gland, 6-compression gland, 7-drive link, 8-actuating unit, 9-rocking arm, 10-preloading spring, 11-flashboard, 12-flashboard ceramic seal circle, 13-valve seat, 14-valve seat ceramic seal circle.
The specific embodiment
Embodiment: as shown in the figure, a kind of single disc pottery rotating feeding valve, it comprises upper valve body 1 and lower valve body 2, said upper valve body 1 is connected by fastener 3 with lower valve body 2, said upper valve body 1 interior installation valve rod 4, valve rod 4 is fixing with upper valve body 1 by packing gland 5 and compression gland 6, the upper end connection for transmission bar 7 of valve rod 4, and drive link 7 connects actuating unit 8; It also comprises rocking arm 9, preloading spring 10, flashboard 11, flashboard ceramic seal circle 12, valve seat 13 and valve seat ceramic seal circle 14; Said lower valve body 2 is funnel type, lower valve body 2 interior installation rocking arms 9, the bottom of valve rod 4 is connected with the fixed end of rocking arm 9; preloading spring 10 is installed in the movable end of rocking arm 9; flashboard 11 is installed in the top of rocking arm 9; flashboard 11 interior installation flashboard ceramic seal circles 12, and rocking arm 9 supports flashboard 11, flashboard ceramic seal circle 12; Said upper valve body 1 interior installation valve seat 13 is installed valve seat ceramic seal circle 14 on the valve seat 13, flashboard ceramic seal circle 12 is close to upper valve body 2 and valve seat ceramic seal circle 14.
Principle of work: horizontally rotate when actuating unit 8 drives drive link 7, band ovable valve stem 4 and drives rocking arm 9, flashboard 11 and flashboard ceramic seal circle 12, realize the function of valve opening and closing.When valve rod 4 drove the rotation of flashboard 11 clockwise directions, flashboard ceramic seal circle 12 was thrown off with valve seat ceramic seal circle 14, and valve is in opening, and medium normally passes through.Otherwise, when valve rod 4 drives the rotation of flashboard 11 anticlockwise directions, flashboard ceramic seal circle 12 and valve seat ceramic seal circle 14 closures, valve is in closed condition.
