Abstract
A check valve dedicated for an air pipe in a compound fertilizer production line comprises a valve body (1), a rotating shaft (2), a valve plate (3) and a rotating handle (4), wherein the rotating shaft (2) is mounted on the valve body (1) through a bearing; the valve plate (3) is fixed on the rotating shaft (2); and the rotating handle is fixed at the tail end of the rotating shaft (2). The check valve has the advantages as follows: 1, the rotating shaft rotates together with the valve plate at the same time, thereby avoiding abnormal abrasion; 2, the bearing is arranged outside an enclosed cavity of the valve body, thereby being free from influences of medium in the valve body; and 3, the end of the rotating shaft extends outside the valve body, and is provided with a rotating handle, so that whether the valve operates normally or not can be checked outside, and further, the rotating handle can be revolved by maintenance personnel regularly, so as to prevent the valve plate from being blocked tightly by impurities.
Description
Technical field
The utility model relates to the one-way valve field.
Background technique
Employed one-way valve mainly is made up of valve body, rotatingshaft, valve plate on composite fertilizer's production line at present.Two kinds of patterns are arranged at present: relatively rotate between first kind of pattern valve plate Upper shaft sleeve and the rotatingshaft, its deficiency is that rotatingshaft and axle sleeve are prone to be worn, and finally cause valve plate to come off because one-way valve uses for a long time, and one-way valve loses check function; Second kind of pattern rotatingshaft and valve plate axle sleeve are fixing to rotate together, but for anti-leak is arranged at bearing in the valve body, has impurity to be prone to damage of bearings in the pipeline, and axle rubs the most at last, causes valve plate to come off, and one-way valve loses check function.The air-flow that when the equipment that is moving loses external power suddenly, (trips suddenly like motor) in the pipeline backwashes to the process equipment at the production line upper reaches, causes damage of facilities.And when rotatingshaft had worn and torn or the impurity jam is arranged, the maintenance man was difficult to find outside valve.Secondly the bump valve body sealing surface is prone to make valve plate to damage because the air-flow in the pipeline is not to weigh to decide, and the air-flow size variation can make the valve plate vibrations.
The model utility content
The purpose of the utility model is exactly to the above-mentioned deficiency of employed one-way valve on the existing composite fertilizer production line; And a kind of composite fertilizer production line special single-way valve is provided; It is made up of valve body, rotatingshaft, valve plate, handle with sleeve; On valve body, valve plate is fixed on the rotatingshaft rotatingshaft through Bearing Installation, and handle with sleeve is fixed on the rotation the tip of the axis.It also has spring, spring seat, and spring seat is fixed on the valve body, and spring one end is fixed on the spring seat, and the other end withstands on the handle with sleeve.
The utility model has the advantages that: 1, rotatingshaft rotates with valve plate together, and rotatingshaft can heel and toe wear; 2, bearing is arranged on outside the valve seal chamber, does not receive medium influence in the valve; 3, it is outer and be provided with handle with sleeve that axle head stretches out valve body, but check valve proper functioning whether outside, and the frequent rotated handle of maintenance man, prevent that valve plate is stuck by impurity; 4, withstand on the handle with sleeve through spring, can stop effectively because of the air-flow size variation makes valve plate vibrations and clash into valve body, prolongation valve plate working life.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
The utility model is made up of valve body 1, rotatingshaft 2, valve plate 3, handle with sleeve 4; On valve body 1, valve plate 3 is fixed on the rotatingshaft 2 rotatingshaft 2 through Bearing Installation, and handle with sleeve 4 is fixed on the end of rotatingshaft 2; It also has spring 5, spring seat 6; Spring seat 6 is fixed on the valve body, and spring 5 one ends are fixed on the spring seat 6, and the other end withstands on the handle with sleeve 4.
Claims (1)
1. composite fertilizer's production line tracheae special single-way valve is characterized in that it is made up of valve body (1), rotatingshaft (2), valve plate (3), handle with sleeve (4), rotatingshaft (2) through Bearing Installation on valve body (1); Valve plate (3) is fixed on the rotatingshaft (2); Handle with sleeve (4) is fixed on the end of rotatingshaft (2), and it also has spring (5), spring seat (6), and spring seat (6) is fixed on the valve body; Spring (5) one ends are fixed on the spring seat (6), and the other end withstands on the handle with sleeve (4).
