Abstract
A diaphragm pump through type inlet valve belongs to the diaphragm pump inlet valve technical field. The utility model provides a diaphragm pump through type inlet valve which can prevent the generation of slurry siltation, deposition as well as erosion of a valve casing. The utility model comprises a valve casing. A valve cone is equipped on the feeding inlet valve seat which is located on the bottom of the valve casing. The valve cone comprises valve nuts the bottoms of which are provided with a rubber pad. The valve nuts are connected with a fastening conduit on the top through a spring. The structural key points of the utility model are that the top of valve casing is provided with a discharging opening; the side part of the valve casing is provided with a valve cover; and a stop rod of the fastening conduit is fixed on a rack inside the valve cover.
Description
Technical field
The utility model relates to a kind of diaphragm pump straight-through type feeding valve, is suitable for the conveying of high concentration solid-liquid two-phase slurry medium.
Background technique
The charging clack box is the feed check valve that is connected with chamber of septum.Traditional charging clack box is fixed on the valve gap by valve seat, valve cone, spring, fastening conduit.Valve opens and closes valve cone to realize the one-way flow of slurry by fluid pressure and spring force.When dnockout was starched, because valve material feeding mouth and discharge port intersect vertically, slip need be through turnover, so the conventional feeds clack box is easier to produce alluvial, precipitation and the washing away valve housing of slip.
Summary of the invention
The utility model is at the problems referred to above, and a kind of diaphragm pump straight-through type feeding valve of producing slurry alluvial, precipitation and valve housing being washed away avoided is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises valve housing, the material feeding mouth valve seat of valve housing bottom is provided with valve cone, and valve cone comprises valve nut, and the bottom of valve nut is a rubber pad, valve nut links to each other by the fastening conduit of spring with the top, the top of its structure outline valve housing is provided with discharge port, and the side of valve housing is provided with valve gap, is fixed with the stop rod of fastening conduit on the support in the valve gap.
The beneficial effects of the utility model: (1) has realized the straight-through of clack box not influencing under the situation that slip flows, and has reduced alluvial, precipitation and the washing away valve housing of slip.When carrying high concentration ground paste, this effect is more remarkable.
(2) reduced cost of production, the new structure that the utility model adopts is that valve housing directly links to each other with diaphragm cavity (having saved bend pipe), has reduced the space of pump, has reduced cost of production.
Description of drawings
Fig. 1 is the utility model structural representation.
In the accompanying drawing, 1 is material feeding mouth, and 2 is valve housing, and 3 is valve seat, and 4 is rubber pad, and 5 is valve nut, and 6 is spring, and 7 is valve cone, and 8 is fastening conduit, and 9 is stop rod, and 10 is support, and 11 is discharge port, and 12 is pin, and 13 is valve gap, and 14 is stud bolt.
Embodiment
The utility model comprises valve housing 2, the valve seat 3 of the material feeding mouth 1 of valve housing 2 bottoms is provided with valve cone 7, valve cone 7 comprises valve nut 5, the bottom of valve nut 5 is a rubber pad 4, valve nut 5 links to each other by the fastening conduit 8 of spring 6 with the top, the top of valve housing 2 is provided with discharge port 11, and the side of valve housing 2 is provided with valve gap 13, is fixed with the stop rod 9 of fastening conduit 8 on the support 10 in the valve gap 13.
Stop rod 9 adopts Z-shaped; Not only make things convenient for the dismounting of self, can also play axially locating effect self.
Utilize stud bolt 14, valve gap 13 and valve housing 2 are fixed as one, realized the axially locating of the support 10 of fixing fastening conduit 8, pin 12 prevents that support 10 from rotating.
