Description
Technical Field
The utility model belongs to the technical field of the diaphragm pump, concretely relates to cone valve case of large-scale diaphragm pump.
Background
The valve core of the cone valve at the hydraulic end of the large diaphragm pump is positioned inside the box body of the feeding valve and the discharging valve and is an important key part and a quick-wear part at the hydraulic end of the diaphragm pump. In the operation process of the large diaphragm pump, a cone valve core in a feeding and discharging valve box body moves up and down periodically along with the reciprocating motion of a rubber diaphragm, and valve rubber in the core and a valve seat impact periodically in the process. The field operation practice of the large diaphragm pump shows that the extrusion expansion amount of the valve rubber should meet the impact contact area between the valve core and the surface of the valve seat, namely, the valve cone in the valve core should not collide with the valve seat in the up-and-down movement process. This requires that the valve nut and the valve rubber be assembled and loosened in strict accordance with the locking torque, thereby ensuring that the extrusion expansion amount of the valve rubber does not change.
The diaphragm pump cone valve case of traditional structure only utilizes the moment spanner to lock the valve nut usually, makes the volume of expanding of valve rubber reach operation requirement through giving locking torque value, but this kind of single locking mode is changeed the easy emergence of back and is become flexible experiencing certain number of times and assaulting, leads to the volume of expanding of valve rubber to reduce, produces the collision effect of valve cone direct contact disk seat.
In addition, the guide frame part of the prior cone valve core is assembled in a hot loading mode, so that the guide frame falls off after the valve core collides with the valve seat for many times, the continuous operation rate of the diaphragm pump is reduced, and potential safety hazards are caused.
