According to the hydraulically-controlled opening and closing valve, the pressure of a fluid is used fully for controlling opening and closing of the valve, so that the structure is quite simple, the manufacturing cost is effectively reduced, and the valve is quite convenient to maintain and disassemble.
Description
Technical field
The present invention relates to valve, be specially a kind of fluid-control starting and stopping valve.
Background technique
The valve that on boiler circulation loop and some engineerings, usually will adopt some to open and close by liquid control.These valves are by the switching of flowing control valve of liquid, flow of fluid, and valve opening (or closed), when no liquid flows, valve closes (or unlatching).But the many pressure by liquid in the electronic component induction pipeline of present this fluid-control valve, and then send coherent signal to valve, open (or closed) valve by corresponding element, make that the structure of valve is comparatively complicated, and the element that adopts is more, cost of production is higher, and repair demolition is quite inconvenient.Therefore press for a kind of fluid-control valve simple in structure.
Summary of the invention
The present invention provides a kind of fluid-control starting and stopping valve for solving fluid-control valve complex structure and the high technical problem of cost commonly used at present.
The present invention realizes by the following technical solutions: a kind of fluid-control starting and stopping valve, comprise valve body and piston cylinder, and be divided into the influent stream chamber in the valve body and go out to flow chamber two-part, influent stream chamber and go out to flow and offer valve port between the chamber; The upper and lower port of piston cylinder is respectively equipped with upper end cap and lower end cap; The setting that matches with valve port of valve rod lower end valve plug, upper end piston and piston cylinder inwall are equipped with, and valve rod inside is provided with port hole, and the position that is positioned at the piston bottom on the sidewall of piston cylinder has liquid entering hole.
Piston is divided into upper piston chamber 14 and lower piston chamber 15 with piston cavity.Liquid entering hole is connected with water pump by pipeline.During work, water pump pumps into the lower piston chamber with liquid by liquid entering hole, when the pressure of piston cavity inner fluid is greater than the hydrodynamic pressure in the upper piston chamber instantly, piston moves up under the fluid pressure effect in lower piston chamber, and the drive valve plug moves up, valve plug is opened, and the fluid in the upper piston chamber flows into out the stream chamber through the port hole on the valve rod; Fluid in the influent stream chamber through the influent stream chamber, valve port, go out to flow the chamber and outlet is flowed out; When water pump stops downward piston cavity and carries liquid, fluid pressure in the lower piston chamber reduces, go out to flow in the port hole inflow upper piston chamber of fluid through valve rod in the chamber, piston moves down under the pressure effect of the fluid that enters the upper piston chamber, valve plug also moves down simultaneously, be closed whole valve closing up to valve port.
Further, be provided with spring between piston and the upper end cap.
If the fluid of turnover valve is gas, then because the pressure of gas relatively less than liquid, therefore is provided with spring between piston and upper end cap, when liquid entering hole had liquid to enter, piston was pushed upwardly, and spring is compressed; When water pump quit work, piston moved down under the acting in conjunction of spring and gas, and valve plug is closed valve port thereupon.Arranging of spring can be finished resetting of piston under the situation of gas pressure deficiency.
The present invention adopts simple mechanical structure to realize the switch of valve, and the pressure that has taken full advantage of fluid self comes the unlatching of control valve, makes structure very simple, and effectively reduces manufacture cost, and repair demolition is also very convenient.

Embodiment
A kind of fluid-control starting and stopping valve comprises valve body 1 and piston cylinder 2, is divided into influent stream chamber 3 in the valve body 1 and goes out to flow chamber 4 two-part, influent stream chamber 3 and go out to flow and offer valve port 5 between the chamber 4; The upper and lower port of piston cylinder 2 is respectively equipped with upper end cap 6 and lower end cap 7; The setting that matches with valve port 5 of valve rod 8 lower end valve plugs 9, upper end piston 10 is equipped with piston cylinder 2 inwalls, and valve rod 8 inside are provided with port hole 11, and the position that is positioned at piston 10 bottoms on the sidewall of piston cylinder 2 has liquid entering hole 12.
Be provided with spring 13 between piston 10 and the upper end cap 6.
Arrow among Fig. 2 is represented the flow direction of fluid, and the fluid that is used for hydraulic control among the figure enters lower piston chamber 15 through liquid entering hole 12, and valve plug 9 and piston 10 move on all, fluid through valve port 5, go out to flow chamber 4 and flow out valve bodies 1.
Be applied in schematic representation in the boiler pipe as Fig. 3 for the present invention.The pipe-line system of boiler 16 comprises rising pipe 17 and water return pipeline 18, and rising pipe 17 is connected with water return pipeline 18 by radiating fin 19, forms a circulation loop; Be serially connected with water pump 20 and safety check 21 on the rising pipe 17, be serially connected with fluid-control starting and stopping valve 22 on the water return pipeline 18; Rising pipe 17 also is connected with a control valve 23 and is connected with the liquid entering hole 12 of fluid-control starting and stopping valve 22.When water pump 20 started, the pressure of water pump was opened fluid-control starting and stopping valve 22 by control valve 23, and systemic circulation is unimpeded; When water pump 20 stopped, rising pipe 17 was closed by safety check 21 controls, and fluid-control starting and stopping valve 22 is because water pump 20 stops, and control valve 23 loses pressure, and the valve plug 9 of fluid-control starting and stopping valve 22 resets under the effect of spring 13 and backwater and closes, and systemic circulation stops.This fluid-control starting and stopping valve also can be used on the pilot line of other fluid.
