Description
Technical field
The utility model relates to liquid flow control reversal valve, relates in particular to plunger rod-pulling type four position switching valves that are used for pressure-exchange formula energy recycle device.
Background technology
The reverse osmosis membrane desalinization is generally adopted in countries in the world, and China was existing in recent years to develop on a large scale very much, also will become the mainstream technology of China's desalinization industry from now on.
Energy recycle device is one of key equipment of reverse osmosis seawater desalination system, and is most important to significantly reducing system's operation energy consumption and making the water cost.Energy recycle device can be divided into two classes according to operation principle: hydraulic turbine formula and positive displacement formula.The former is representative with the HTC (Hydraulic TurboCharger) of U.S. PEI company, needs usually through " pressure energy-shaft work-pressure energy " two step conversion process, and energy recovery efficiency has only 50%-75%.The latter is representative with the PX (PressureExchanger) of U.S. ERI company then, only needs through " pressure energy-pressure energy " step conversion process, and energy recovery efficiency becomes the emphasis of domestic and international research and extension up to 90%-95%.
At present the employed energy recycle device of China's desalination by reverse osmosis engineering is based on the positive displacement formula, regardless of different kinds of, whole dependence on import.Therefore, energy recovery technology and device that research and development has China's independent intellectual property right, to breaking the external product monopoly position in market at home, further reduce the equipment investment of desalting plant, promote that the development of domestic desalinization industry is all significant.
Pressure-exchange formula energy recycle device is a kind of of positive displacement formula energy recycle device, and valve is the critical component of controlled pressure exchange type energy recovery device running, and valve control effect is directly connected to continuity, stability, the accuracy of operation.The valve of liquid flow control usefulness mainly contains magnetic valve and motor-driven valve.Magnetic valve mainly contains 2/2-way magnetic valve and two-bit triplet magnetic valve at present.Though the former can satisfy the requirement of fluid flow, it requires to guarantee certain pressure reduction between the import of magnetic valve and outlet when opening, and when the outlet pressure of magnetic valve during greater than the inlet pressure certain value, then the closing function of magnetic valve lost efficacy.This magnetic valve is when being used for control band press liquid when flowing in addition, and the opening and close to close of its moment causes bigger pressure oscillation.No matter be 2/2-way or two-bit triplet magnetic valve,, then often need a plurality of parallel operations to use, thereby make process operation complicated for the occasion that needs the liquid flow switch operation; The latter uses more aspect air-flow control, and aspect control band press liquid, not only Kong Zhi flow is less, and has the big problem of pressure oscillation, is difficult to satisfy the occasion of big flow band press operation.
In seawater or the brackish water desalination process, its strong brine pressure can be realized energy-conservation purpose by adopting pressure-exchange formula energy recycle device.Its process is one, and liquid collecting body flow is big, pressure reduction is high, the flow process that needs continuous reciprocating reversing to open and close.Therefore, the control valve that this energy recycle device adopts is a key technology, can't use conventional magnetic valve and motor-driven valve.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of plunger rod-pulling type four position switching valves that are used for pressure-exchange formula energy recycle device are provided.The valve group of suitable four simple valve of this valve, compact conformation is used to control liquid different flow and pressure operation, and is simple, convenient, and control is accurate, efficient, and the life-span is long.
The utility model is used for plunger rod-pulling type four position switching valves of pressure-exchange formula energy recycle device, it comprises valve body, be arranged on the plunger rod-pulling type guide rod in the described valve body, perpendicular two groups of its axis and described valve body and guide rod axis that axially are respectively arranged with of described valve body and guide rod upper edge valve body and guide rod advance, outlet, two groups are advanced, the outlet through hole, described every group is advanced, outlet comprises a pair of import, a pair of outlet, described every group of through hole comprises an import through hole, an outlet through hole, described every pair is advanced, outlet, each advances, the outlet through hole is respectively along valve body, guide rod axially to advance, go out or go out, the sequence alternate setting of advancing, described guide rod can axially move up and down along valve body, one group on a pair of import in one group on the described valve body is imported and exported and the described guide rod is advanced, an import through hole is communicated with in the outlet through hole, when an outlet through hole on a pair of outlet and the described guide rod cuts off mutually, another is organized on a pair of outlet during another group on the described valve body is imported and exported and the described guide rod, one of through hole outlet of outlet through hole is communicated with, and a pair of import cuts off mutually with an import through hole on the described guide rod.
The utility model valve is compared with motor-driven valve with existing plunger type dibit reversal valve and magnetic valve, at any time these plunger type four position switching valve doors can accurately be controlled a pair of low pressure sea intake, the outlet of a pair of high pressure sea water is in unlatching, another is in closed condition to low pressure sea intake, the outlet of a pair of high pressure sea water, therefore these plunger type four position switching valves are in the energy recycle device of band baric flow hydrodynamic body, and the commutation of control high and low pressure liquid is easier, accurate, efficient.The utility model has simple in structure, and seal is few, and is reliable, easy, the advantage that control is accurate, efficient, the life-span is long.
