Energy-saving multifunctional clamping pipe control valve

Abstract

The invention discloses an energy-saving multifunctional clamping pipe control valve, which comprises a valve body, an upper end cover with a through hole, a lower end cover with a through hole, a middle ring, an elastic clamping pipe, a filter assembly, an electromagnetic coil and a quick joint; the upper end of the valve body is fixedly connected with the upper end cover, and the lower end of the valve body is fixedly connected with the lower end cover; the elastic clamping pipe is arranged in the cavity of the valve body; a buffering cavity is formed between the outer side of the elastic clamping pipe and the valve body; the upper end cover is provided with a fixed seat protruding into the inner cavity of the valve body; the middle ring is sleeved on the middle part of a bolt; and the filter assembly passes through the side wall of a lower valve cover, the electromagnetic coil assembly is arranged on the side wall of the valve body, and the quick joint passes through the side wall of an upper valve cover. The control valve is suitable for impurity-containing water or weak corrosive liquid; the power of the electromagnetic coil is only about 10W, so the velocity of opening and closing the valve can be automatically adjusted, the pressure is automatically stabilized, and the filter is automatically flushed; and when the electromagnetic coil cannot work, the control valve has manual opening and closing function.

Description

technical field [0001] The invention relates to a valve used for spraying equipment, in particular to an energy-saving multifunctional pinch control valve. Background technique [0002] When the existing sprinkler dust removal system equipment is installed and used, the following defects usually occur: 1) The valve controlling the opening of the spray gun in the sprinkler dust removal system equipment is often blocked or stuck due to impurities in the water (such as stones or coals, etc.) , which affects the normal operation of the equipment; 2) The direct-lift solenoid valve commonly used in the existing spray dust removal system equipment has a large lifting force and a large electromagnetic coil power (usually between 20 and 30W), resulting in large heat generation and long-term maintenance. Time work is easy to burn; 3) moreover, because the change of pressure in the valve waterway can cause spray gun to shake; Therefore, it is the purpose of the present invention to pr...
