Abstract

The utility model relates to an energy saving inching valve. The utility model is characterized in that a valve body is a piston sleeve; the lower part of a piston is connected with a main valve clack. The piston moves up and down to cause the main valve clack to cover a fluid passage opening which is arranged on the interlayer of the interior of a valve pipeline. An inflow passageway and an outflow out pipeline cause a high pressure chamber, a piston chamber and a low pressure chamber to be communicated. A control valve is arranged on the outflow pipeline. The control valve is operated to control the opening and closing of a pipeline valve. The operation of the pipeline valve with a large diameter is convenient. The utility model modelthe advantages of good structure performance and sealing performance, no phenomena of water running, water overflow, water drop and water leakage, simple structure, and easy fabrication.

Description

Energy-saving micro-valve

The utility model belongs to the improvement of pipeline valve structure.

Pipeline valve works to regulate flow on pipeline.During unlatching, fluid flows to the low pressure place from high pressure in pipeline, and when closing, zone of high pressure and low pressure area are opened by isolated, and fluid is static not to flow.And the pipeline valve that uses at present exists the phenomenon of run, drip, leak, especially bigger pipeline valve also to have the problem that volume is big, operation is not nimble owing to the problem of this body structure.

The purpose of this utility model designs a kind of energy-conservation micro valve exactly, to solve above-mentioned existing problems.

Principle of the present utility model is that under the effect of a less power, the pressure reduction that utilizes valve front and back fluid itself to exist is realized the open and close of big valve.Structure of the present utility model is, has interlayer that valve pipe is divided into hyperbaric chamber and low-pressure cavity in the pipeline of valve, and the main body of valve has the fluid through port on the interlayer in hyperbaric chamber, and there is main valve clack the top of through port, and main valve clack can cover on through port hermetically; There are connecting rod and piston to join on the main valve clack; Valve body is an airtight piston sleeve, and piston operation up and down comparatively hermetically within it has the spring that acts on piston in the piston cavity that forms between piston and piston sleeve; And having flow channel that hyperbaric chamber is communicated with piston cavity, this flow channel can be an external pipe, also can be produced on the piston or between piston and the piston sleeve; Between piston cavity and low-pressure cavity, there is external outflow pipeline that they are communicated with, control valve arranged flowing out on the pipeline; And the cross section of control flow channel is less than the cross section of flowing out pipeline; Piston area is greater than the area of main valve clack.

By as can be seen above-mentioned, the energy-conservation micro valve that the utility model is designed only needs the operation minor valve just can control the Push And Release of big valve, thereby has solved the run, drip, leak phenomenon of big valve, and makes the operation of big valve very nimble.It has simple in structure, makes to be easy to advantage.

Accompanying drawing 1 is a Figure of abstract also, is the structural representation of the designed energy-conservation micro valve of the utility model.1 is interlayer among the figure, and 2 is main valve clack, and 3 is connecting rod, and 4 is intake channel, and 5 is piston, and 6 is spring, and 7 is control valve, and 8 is outlet pipe.As can be seen from the figure, behind closed control valve, the piston cavity inner fluid becomes static, and constantly has fluid to be injected into by hyperbaric chamber by flow channel, and the piston cavity internal pressure of filling with behind the fluid is a static pressure, and directly acts on piston area; To act on the main valve clack face side pressure very little and fluid flows to low-pressure cavity from hyperbaric chamber, and under the effect of spring, piston moves down, and main valve clack is covered the fluid through port, and the pressure of hyperbaric chamber is big more, and is airtight tight more, thereby pipeline valve is closed.After opening control valve, because the rate of outflow is greater than inflow velocity, makes the piston cavity internal pressure diminish, and make the pressure that acts on the piston area become mobile side pressure, move thereby make on the piston, the main valve clack breakdown, pipeline valve is opened.And the flow of adjustment control valve, with regard to the height of rising of may command piston or decline, thus the open amount of controlling plumbing fixtures valve.The utility model is directive in using installation.

The energy-conservation micro valve that the utility model is designed can be used for the conveyance conduit of various fluids, as water, gas, vapour etc., especially on large diameter pipeline, more can show its advantage.Its control valve and flow out pipeline and can be installed in the operating room than distant positions can adopt manually operated valve or solenoid valve etc., the operation of being more convenient for like this.Flow channel can be made into tube shaped (as accompanying drawing), also can be the ostium that is produced on the piston, or the inflow groove between piston and the piston sleeve.The material of piston, connecting rod, main valve clack can be selected lightweight material (as plastics) for use; Its size dimension is the same with spring pressure, needs to calculate according to hydrodynamic pressure, pipe diameter etc.
