Abstract

The invention discloses an ore pulp flow control and adjustment valve and a control method thereof. The ore pulp flow control and adjustment valve comprises an outer valve barrel, a valve cover plate, a cylinder bracket, a shaft sleeve, a valve seat, a valve shaft, a valve core, a cylinder and an inner valve barrel, wherein the inner valve barrel is arranged in the outer valve barrel, and is matched with the outer valve barrel through pressing bolts; an ore pulp overflow opening is formed in the upper end of the inner valve barrel. An ore pulp storage device, namely the inner valve barrel, is arranged in the outer valve barrel, so that ore pulp jetted from a gap between the valve core and the valve seat can only act on ore pulp stored in the inner valve barrel, and the stored ore pulp is used for counteracting the impact energy of sequentially jetted ore pulp; therefore, direct action of the impact energy generated by ore pulp jetting on a valve body is avoided, and the service life of the ore pulp flow control and adjustment valve is finally prolonged.

Description

technical field [0001] The invention relates to a regulating valve, in particular to a pulp flow control regulating valve and a control method thereof. Background technique [0002] No matter the water valve, air valve, slurry valve or other regulating valves have a common feature, that is: in the working state, when the opening of the valve becomes smaller, the fluid velocity passing through the valve outer cylinder will increase significantly, and the scouring energy of the liquid will increase significantly. It will also increase significantly, which will cause greater impact and wear on the valve body, affecting the service life of the regulating valve. For the use of regulating valves, it is an industry consensus that "it cannot be used with a small opening for a long time". As for the slurry control valve, the situation is even more severe. [0003] First of all, due to the characteristics of the ore slurry, the slurry contains a large amount of high-hardness quartz ...
