Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples, which are not intended to limit the present invention.
As shown in fig. 1, the embodiment of the present invention includes an upper valve body 1, a lower valve body 2, a valve seat 3, a conical valve core 4, a guide sleeve 5 and an upper valve cover 6. The valve seat 3 is located between the upper valve body 1 and the lower valve body 2, and the valve seat 3 is connected to the upper valve body 1 and the lower valve body 2 by flanges, which are fastened by bolts. The guide sleeve 5 is fixed at the lower end of the upper valve cover 6 by a flange, meanwhile, an inner hole of the guide sleeve 5 and a valve rod of the conical valve core 4 are arranged oppositely up and down, and after the valve rod enters the inner hole of the guide sleeve 5, the valve rod and the guide sleeve are arranged in a damping clearance fit mode.
The working principle of the embodiment is as follows: when the ore pulp valve is opened slowly and the cone valve core 4 is opened, the valve rod of the cone valve core 4 moves upwards in the guide sleeve 5, ore pulp on the valve rod in the guide sleeve 5 flows downwards from the damping gap, and due to the damping effect, the higher the lifting is, the longer the damping length is, the larger the damping is, the slower the lifting speed is, and the lifting force is smaller and smaller, and finally the lifting height is reached, and basically no impact sound is generated; the situation is opposite when the cone valve core 4 falls, and although the damping force is smaller when the cone valve core falls, the falling speed of the cone valve core in ore pulp is much slower than that of the cone valve core without damping, so that the impact sound and the water hammer sound are much smaller.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
