Abstract

The invention discloses a hydraulic pressure control valve which comprises a shell. A liquid inlet pipe is fixedly connected with the center of one end of the shell. A liquid outlet pipe is fixedly connected with the center of the other end of the shell. A flow dividing mechanism is arranged at the center of the interior of the shell. The inner walls of the two sides of the shell are each providedwith a pressure adjusting mechanism. The bottoms of the outer walls of the two sides of the shell are each provided with a maintaining mechanism. The flow dividing mechanism comprises a first cone body and a second cone body. The bottom end of the first cone body is fixedly connected with the bottom end of the second cone body. By arranging the flow dividing mechanism, liquid entering the shell can be evenly divided, the liquid entering pressure is reduced, the interior of the control valve is protected, and damage and consumption are reduced; and by arranging the pressure adjusting mechanisms, the liquid entering amount can be automatically adjusted, the structure is simple, the adjusting effect is good, the damage of liquid pressure to the control valve is effectively reduced, sensors,controllers and other precise apparatuses are less used, cost is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to a control valve, in particular to a liquid pressure control valve, and belongs to the technical field of special electric equipment. Background technique [0002] A pressure control valve is a valve used to control and regulate the pressure of liquid flow in a hydraulic system. This type of valve works on the principle that the liquid pressure acting on the spool is balanced with the spring force. [0003] In view of this, Chinese Patent No. CN207437485U proposes a hydraulic valve body, which is arranged in the oil inlet pipe through a buffer baffle, and a number of through holes for oil to pass through are provided on the buffer baffle; Chinese Patent No. CN209324767U proposes a replacement For the directional hydraulic valve, a limit spring is set in the middle of the bottom of the directional control valve cover, and a power spring is set outside the limit spring to provide power for the directional slide rod. However, in t...
