Problems solved by technology

[0003] Common metering pump valve limit sleeves in the market are mostly processed by hollowing out the solid bar and machining blind holes. This kind of valve limit sleeve has high requirements on the processing depth of the blind hole and the bottom of the hole must be processed flat , the processing is difficult, and the processing size is difficult to grasp; and it is difficult to deburr the parts after processing

Abstract

The invention relates to the technical field of metering pumps, in particular to a valve limiting sleeve and a split type valve limiting sleeve. The valve limiting sleeve comprises a valve sleeve, a valve cover and an overflowing limiting component; the valve sleeve is a cavity used for containing a valve ball, and a gap is reserved between the valve ball and the valve sleeve; the overflowing limiting component is detachably mounted at one end of the valve sleeve and limits the take-off height of the valve ball; the overflowing limiting component is provided with a through hole communicating with the cavity, and the through hole is matched with the valve ball to be used for limiting the flowing direction of a medium flowing through the cavity; and an adjusting element is installed at the joint of the valve sleeve and the overflowing limiting component and used for adjusting the take-off height of the valve ball. The valve limiting sleeve has the beneficial effects that the valve limiting sleeve is formed by assembling a plurality of components, so that a traditional valve limiting sleeve is changed into a plurality of detachably mounted components, the machining time is saved, raw materials are saved, the difficulty of a machining process is also reduced, installation, replacement and maintenance are convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of metering pumps, in particular to a valve restricting sleeve and a split valve restricting sleeve. Background technique [0002] The suction and discharge of the metering pump is realized by opening and closing the one-way valve at the inlet and outlet installed in the metering pump. In order to stabilize the flow of the metering pump, the movement of the valve ball needs to be restricted to a certain extent; the valve of the split metering pump The restricting sleeve is used to control the take-off height and left and right swing clearance of the valve ball, so that the medium flows out through the flow hole of the valve restricting sleeve along the periphery of the valve ball. [0003] Common metering pump valve limit sleeves in the market are mostly processed by hollowing out the solid bar and machining blind holes. This kind of valve limit sleeve has high requirements for the processing depth of the bl...
