Abstract
The utility model relates to a diaphragm pump split type feeding-discharging valve cover, belonging to the improvement of the diaphragm pump feeding-discharging valve cover, with features of convenient use and saved material. The diaphragm pump split type feeding-discharging valve cover comprises a valve box with a feeding port and a discharging port. A valve cone in a diaphragm chamber is fixed on the valve seat on the feeding port. A fastening duct is arranged above the valve cone and a cone seat with a sealing gasket is arranged below the valve cone. A spring is arranged between the fastening duct and the cone seat. The pressure cover at the peak of the valve box is fixed on the rabbet of the valve box by a stud and a nut.
Description
Technical field
The utility model relates to a kind of improvement of diaphragm pump charging/discharging valve valve cover structure.
Background technique
Diaphragm pump feeding and discharging clack box is the feeding and discharging one-way valve that is connected with chamber of septum.Clack box is made up of parts such as valve seat, valve cone, spring, fastening conduits, and fastening conduit is fixed on the valve gap.The valve gap of clack box is easy to damage often by the slurry erosive wear in the clack box, needs often to change.But when changing valve gap, be integral replacing, therefore caused the waste of material.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of easy to use, split type charging/discharging valve valve gap of diaphragm pump of saving material is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, and the utility model comprises valve housing, and valve housing is provided with material feeding mouth and discharge port, is fixed with the valve cone in the chamber of septum on the valve seat on the material feeding mouth; The top of valve cone is fastening conduit, and the below of valve cone is the awl seat with sealing gasket, is spring between fastening conduit and the awl seat; The gland on its structure outline valve housing top is fixed on the valve housing seam by stud, nut.
The beneficial effects of the utility model: because the gland on the utility model valve housing top is fixed on the valve housing seam by stud, nut; Can be with existing valve gap separated into two parts, the gland of the easy erosive wear of slurry becomes independent body, can change gland at an easy rate when damaging; Not only easy to use, but also can save great deal of raw materials.
