Abstract
The utility model discloses a synchronous switching valve comprising a first reversing valve, a second reversing valve and a valve rod, wherein the first reversing valve and the second reversing valve are connected through a pipeline; the valve rod is used for simultaneously connecting valve cores of the first reversing valve and the second reversing valve; three hydraulic fluid ports are distributed in a T shape on the first reversing valve, and the hydraulic fluid port in the vertical direction is communicated with one of the other two hydraulic fluid ports when equipment operates; three hydraulic fluid ports are distributed in a T shape on the second reversing valve, and the hydraulic fluid port in the vertical direction is communicated with one of the other hydraulic fluid ports when the equipment operates; and the first reversing valve is connected with the second reversing valve though a connecting pipe, the valve rod traverses the connecting pipe, and two ends of the connecting pipe are provided with seals for separating the first reversing valve and the second reversing valve. The synchronous switching valve has the beneficial effects that: 1, new equipment can be replaced under the condition that the normal work of a hydraulic system is not influenced; and 2, the synchronous switching valve is simple in structure and low in manufacturing cost.
Description
Technical field
This model utility relates to a kind of selector valve, particularly a kind of lubricated synchronous switching valve that faulty equipment and new equipment is switched during with the cooling system overhaul of the equipments of power plant that is used for.
Background technique
The various kinds of equipment of power plant is longer in startup and outage period, and cost is very high, and the lubricated frequent more renew cartridge that needs of filter with cooling system.If it is too high to shut down replacement cost, running state can't be carried out the replacing of filter core.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of synchronous switching valve that can be under electric power factory equipment situation not out of service faulty equipment and new equipment be switched.
Technological scheme: a kind of synchronous switching valve; Comprise first selector valve, second selector valve that connects through pipeline and be connected first selector valve simultaneously and the valve rod of second change-over valve core; Said first selector valve " T " font is distributed with three hydraulic fluid ports, and the hydraulic fluid port during equipment operation on the Vertical direction communicates with a hydraulic fluid port in two other hydraulic fluid port; Second selector valve " T " font is distributed with three hydraulic fluid ports, and the hydraulic fluid port during equipment operation on the Vertical direction communicates with a hydraulic fluid port in two other hydraulic fluid port; Connect through connecting tube between first selector valve and second selector valve, valve rod crosses connecting tube and the connecting tube two ends are provided with the sealing with first selector valve and the separation of second selector valve.Carrying out before faulty equipment and new equipment switch, at first the hydraulic fluid port of new equipment and first selector valve of the said synchronous switching valve of the utility model and two hydraulic fluid ports of residue of second selector valve are being connected, rotation valve rod is realized the switching of oil circuit in equipment running process.
The bypass valve that also comprises the pipeline that connects said first selector valve and the second selector valve both sides hydraulic fluid port respectively.Switch the proper functioning of avoiding influencing hydraulic system when fluid flows at operating valve lever and need in the hydraulic fluid port pipelines on two sides, connect bypass valve respectively, open bypass valve before the switching earlier, switching is closed bypass valve after accomplishing again.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: 1, can under the situation that does not influence the hydraulic system proper functioning, change new equipment; 2, simple in structure, low cost of manufacture.
