Embodiment Construction

[0025] Below in conjunction with the accompanying drawings of the present invention in embodiments, the technical solutions in the embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention rather than all embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art without doing all the other embodiments obtained by creative efforts, fall within the scope of the present invention.

[0026] See Figure 1-4 A valve sealing surface produced by multi-angle grinding apparatus, comprising a housing 1, the housing 1 with the right side of the trigger lever 17 defines a moving groove adapted and defines a limiting groove bottom of the housing 1, through the moving groove 17 of the trigger lever motion thereby stimulating the dielectric plate 18 motion, thereby changing the opposing area of ​​the positive electrode plate 19 and the negative elec...

Abstract

The invention relates to the technical field of valve machining, and discloses a multi-angle grinding device for valve sealing surface production. The device comprises a shell, wherein a clamping groove is formed in the inner wall of the middle of the shell; a rotating shaft is movably connected to the inner wall of the middle of the shell; a non-magnetic plate is fixedly connected to the inner wall of the middle of the rotating shaft; a connecting rod is fixedly connected to the outer side of the rotating shaft; and an electromagnet is fixedly connected to the middle inner wall of the rotating shaft. According to the multi-angle grinding device for valve sealing surface production, a trigger bar drives dielectric plates to move, the dielectric plates drive a positive plate and a negative plate to operate, and then a ball and a piezoresistor are used in cooperation, so that the effect of controlling the electromagnet and a conductive pole to be powered on and powered off is achieved, the trigger bar is pushed towards the left side along the inner wall of a movable groove, the dielectric plates generate relative displacement, the relative area of the positive plate and the negative plate is gradually reduced, the voltage between the two plates is gradually reduced, at the moment, the minimum path voltage of the piezoresistor is reached, the electromagnet is powered on to generate a magnetic field, and a static contact is in contact with a movable contact and the conductive pole is powered on.

Description

Technical field [0001] The present invention relates to a valve processing technology, and in particular to a valve sealing surface angles production sanding apparatus. Background technique [0002] Valves are widely used in industry, agriculture and life are involved in life, a wide range of valves, ball valves have more common, triangle valve, globe valve, ball valve in which the use is more common, as the ball valve spool an important part, is attached to the valve body, acts to control fluid flow, the valve body in the process in order to prevent water leakage at the seal surface when the valve element is stopped, the need for grinding the sealing surface of the valve body is to ensure the sealing surface is smooth. [0003] Commonly used today abrasive grains to polish the valve body flow, but the abrasive grains in the grinding process some of the pits formed valve sealing surface, which is bonded to the lower surface of the valve seat sealing accuracy, since the grinding h...
