Embodiment:
Fig. 1 and Fig. 2 are one embodiment of the present of invention, and main invention thought is with fertilizer spreading tank 4 among the figure, and screen pack 3 and regulator 1 design are as a whole, and wherein regulator 1 is arranged at the end of water inlet pipe 6.
The embodiment that Fig. 1 and Fig. 2 provide is the float-type regulator, is made up of pressure regulation cushion 1-1, the float 1-3 and the admitting pipe joint that are arranged in the water inlet pipe; The pressure regulation cushion is the endless elastomeric of band internal tooth 1-2; Float 1-3 places on the internal tooth of pressure regulation cushion; Between float and pressure regulation cushion, form the pressure regulation passage; The pressure regulation aisle spare is in theory less than water inlet pipe water inlet area.Therefore the water flow velocity in the pressure regulation passage is higher, hydraulic pressure is lower, there is pressure reduction in the float upper and lower surface, float pushes elasticity pressure regulation pad internal tooth under this differential pressure action, float moves down, when float upper and lower surface pressure reduction equates with the elastic force of elasticity pressure regulation pad, float is in poised state, because pressure regulation passage water inlet area moves down and reduces with float, flow of inlet water decreases, the pressure reduction of the big more float upper and lower surface of system's hydraulic pressure is big more, and the decrement that float is exchanged compression elasticity pad internal tooth is big more, and the pressure regulation channel cross-sectional area is more little, flow of inlet water is then more little, when the system water pressure drop was low, the pressure reduction of float upper and lower surface reduced, and then float moves under the elastic force effect of elasticity pressure regulation pad, pressure regulation passage water inlet area increases, thereby guarantees that fertilizer spreading tank 4 internal pressures are stable.
The float 1-3 of this embodiment can be top in shape, spherical all tapers, and float is stuck in the boss of water inlet pipe end.
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.
Another embodiment that Fig. 3 provides is arranged on the piston type regulator 8 on the water inlet pipe tube wall, and regulator 8 is made of two groups of piston pairs and lever 8-7.
Big piston 8-4 is connected with lever 8-7 by support 8-8 with valve piston 8-5; Cylinder cap 8-1 and big piston cylinder are set by being threaded in big piston cylinder end portion; Pressure spring 8-2 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. 4 is the 3rd 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 second, third embodiment of the present invention 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.
