Embodiment:
Fig. 1 is an embodiment of the present utility model, main design philosophy is with fertilizer spreading tank 4 among the figure, 1 design of screen pack 3 and regulator is as a whole, and wherein the two groups of piston pairs and the lever 1-7 that are arranged on the water inlet pipe tube wall of regulator 1 constitutes, and is arranged at the end of water inlet pipe 6.
Fig. 1 has also illustrated water inlet pipe 6 and the installation site of outlet pipe 2 on the fertilizer spreading tank end cap, and the shape of screen pack can be guard or plain net, is installed in the outlet pipe end.
Big piston 1-4 is connected with lever 1-7 by support 1-8 with valve piston 1-5 among Fig. 1; Cylinder cap 1-1 and big piston cylinder are set by being threaded in big piston cylinder end portion; Pressure spring 1-2 is set between cylinder cap and big piston; Adjust the pretightning force of pressure spring by cylinder cap.
Because the sectional area difference of big piston cylinder and valve piston cylinder, therefore there is difference in the water system pressure that acts on big piston and valve piston end face, when this pressure difference value during greater than the pretightning force of pressure spring, promptly promoting big piston moves outside water inlet pipe, lever moves valve piston in water inlet pipe, compress pressure spring simultaneously; Spring increases because of pressurized elastic force, when spring force increases to system to the pressure difference value of big piston and valve piston, is in poised state; When system pressure increased, system increased the pressure difference value of big piston and valve piston, and poised state is broken, and big piston moves outward, moves in the valve piston; When system pressure reduced, system reduced the pressure difference value of big piston and valve piston, and same balance is broken, and moves in the big piston, and valve piston moves outward; The mobile water inlet area that has changed in the water inlet pipe of valve piston, flow of inlet water changes thereupon, and system pressure increase then flow of inlet water reduces, and system pressure reduces then flow of inlet water increase; Thereby the pressure stability in the assurance fertilizer spreading tank.If piston is identical, also can achieve the goal by adjusting balance pivot.
Fig. 2 is another embodiment of the utility model piston type regulator, and regulator 7 is made of the staged piston pair among the figure.
The big end of piston and big piston cylinder 7-1 cooperate, and small end and valve piston cylinder 7-5 cooperate; Through hole 7-6 is set in the piston in the heart; Valve piston cylinder and water inlet pipe are cast as one, and piston small end move left and right in the valve piston cylinder can change the water inlet area of water supply connector; Big piston cylinder and valve piston cylinder are by being threaded; Between big end of piston and valve piston cylinder spring 7-3 is set, the pretightning force of spring can be by the connecting thread adjustment of big piston cylinder and valve piston cylinder.
Through hole 7-6 by piston causes the back that enters the big end of piston in the big piston cylinder to the water in the water inlet pipe, makes the big end back of piston and small end front have the pressure that equates, because the compression area difference has just produced the inside pressure differential of piston.Piston remained static when the elastic force of this pressure difference value and spring equated, piston moves in water inlet pipe during greater than spring force, and piston moves outside water inlet pipe during less than spring force.
By adjusting the pretightning force of spring, can adjust the force value in the fertilizer spreading tank, usually the pretightning force of spring and the pressure difference value that system's controlled pressure produces on piston balance each other, because the big end of piston and small end face product moment value are quantitative, so when the hydraulic pressure of system increases, when surpassing system's controlled pressure, then inside pressure differential increases, piston compresses spring and moves inward, the piston small end stops the intake tunnel of water inlet pipe, flow of inlet water is reduced, if system pressure reduces, then outside pressure difference value reduces, piston is then promoted to move outside water inlet pipe by the elastic force of spring, open the intake tunnel of water inlet pipe, flow of inlet water is increased, guaranteed the force value that the pressure stability in the fertilizer spreading tank is being preset.
The big piston cylinder is provided with air vent 7-4, and its purpose is to avoid to produce air pressure because of the piston motion.
The advantage of two embodiment of the present utility model is that system's controlled pressure is adjustable, by adjusting the pretightning force of spring, can adjust the force value in the fertilizer spreading tank.
