Description
Technical field
The utility model belongs to valve field, relates in particular to the constant voltage three-way control valve.
Background technique
In fields such as petrochemical industry, electronics and semiconductor, metallurgy, need the equipment of sealing, in case solution contact as air etc. with external substance and causes solution contaminated, solution quality decline in the process of storage.When seal container uses, the impact that the fluctuation that needs to consider liquid level in container brings the normal use of container.Because, when in container, liquid level changes, container inner pressure changes thereupon, there is difference in the atmospheric pressure that the pressure in container will be outer with container like this, when this difference surpasses certain restriction, easily causes container deformation even to break, thereby causes accident.Designed for the problems referred to above the constant voltage three-way control valve that structure is simple and direct, fabricating cost is low.
The model utility content
The utility model is intended to overcome the defect of prior art, and a kind of constant voltage three-way control valve is provided, and has advantages of that structure is simple and direct, fabricating cost is low.
The technological scheme that realizes above-mentioned purpose is as follows:
The constant voltage three-way control valve, comprise handle, valve body, spool, valve rod, pressure-detecting device, in described valve cavity, spool is installed, and described valve rod one end is fixedly plugged on spool, and the described valve rod the other end and handle are hinged; Described valve body is provided with two liquid outlets and a liquid entering hole, all be connected with respectively fluid pipeline and input duct on described liquid outlet and liquid entering hole, described fluid pipeline and input duct all are equipped with pressure-detecting device, and are connected with frequency variator, also are connected with pressure pump on described frequency variator.
Described pressure-detecting device is pressure transducer.
Described fluid pipeline and input duct are steel pipe or plastic tube.
The utlity model has following beneficial effect:
The utility model structure is simple and direct, constant pressure during work; Adopt fluid pipeline and input duct that pressure-detecting device all is installed, make three-way control valve in-out end pressure to be consistent preferably.In addition, fluid pipeline and input duct adopt steel pipe or plastic tube to make, and material is selected extensively, to have reduced the equipment making cost.Also have the sealing gasket sealing between spool and valve body, make the utilization ratio of solution improve.
The accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms the part of specification, with embodiment one of the present utility model, is used from explanation the utility model, does not form restriction of the present utility model.In the accompanying drawings:
