Problems solved by technology

[0002] In the prior art, the general hydraulic control valve has a structure in which a main valve plate is hinged through a valve shaft in the valve body, and a discharge hole and a small valve plate are arranged on it, and there is a horizontal valve connected to the small valve plate in the valve body. The control rod and the control cylinder connected with the horizontal control rod are set on the side wall of the valve body, and the upper and lower chambers of the control cylinder are respectively connected to the front and rear of the main valve. The pressure difference between the front and rear of the main valve is used to control the pressure difference between the main valve plate and the small valve plate. Fast and slow, to achieve the elimination of pump stop water hammer and non-return function, because the control cylinder is located on the side wall of the main valve, the valve width is large, the floor space is large, and maintenance and testing are inconvenient

Abstract

The invention discloses a sloping plate energy saving type multifunctional valve, which comprises a valve body, a valve plate, a cam component and a controlling mechanism. The valve plate is fixed in the valve body through a valve plate rotating axle, a discharge orifice is arranged on the valve plate, the cam component corresponding to the discharge orifice is fixed on the valve plate through a cam rotating axle, the valve body comprises a right valve body and a left valve body which are connected through bolts, the controlling cavity of the controlling mechanism is fixed at the top part of the left valve body, the controlling cavity is longitudinally divided into an upper controlling cavity and a lower controlling cavity in sequence, an outlet bypass pipe connected with the outlet opening end of the valve body is arranged in the upper controlling cavity, an inlet bypass pipe connected with the inlet opening end of the valve body is arranged in the lower controlling cavity, a rotating wheel contacting with the cam component in a rolling way is arranged at the bottom end of a controlling rod, a chain or a hinge is arranged on the controlling rod, and the other end of the chain or the hinge is connected with the cam component. The invention has the advantages that the structure is simple and compact, the assembly and the maintenance are convenient, the floor space is small, and the security and the reliability are high.

Description

technical field [0001] The invention mainly relates to the field of pump valves, in particular to a slant plate energy-saving multifunctional valve. Background technique [0002] In the prior art, the general hydraulic control valve has a structure in which a main valve plate is hinged through a valve shaft in the valve body, and a discharge hole and a small valve plate are arranged on it, and there is a horizontal valve connected to the small valve plate in the valve body. The control rod and the control cylinder connected with the horizontal control rod are set on the side wall of the valve body, and the upper and lower chambers of the control cylinder are respectively connected to the front and rear of the main valve. The pressure difference between the front and rear of the main valve is used to control the pressure difference between the main valve plate and the small valve plate. Fast and slow, to achieve the elimination of pump stop water hammer and check function. Si...
