Description
(1) technical field: the utility model relates to the switch valve series products, especially a kind of maglev type smart valve.
(2) background technique: valve be a kind of be widely used in industry, agricultural, national defence and with people's routine work closely-related engineering goods of living.Valve is the important composition parts in the pipe-line system, and quantity is big, is one of main source of leaks in the system, is to solve an energy-conservation vital ring.Valve seal is the ability that stops dielectric leakage.Dielectric leakage mainly contains interior leakage and leaks outside two kinds.Interior leakage influences valve and blocks the ability of medium and the normal operation of equipment.Leak outside be medium from the valve internal leakage outside valve.It directly influences safety in production, economy of energy loss, environmental pollution.Therefore, it is unallowed at all leaking outside, and valve must have reliable sealing performance.
In existing valve mechanism, interior leakage sealing position is the matching surface of open-shut device and valve base chamber.Leak outside is filler and the joint of the cooperating of valve rod and stuffing box, valve body and valve gap.The first kind of sealed nature that leaks outside is motive sealing character, also is the principal mode of seal failure.At different leakage rates, country variant and industry have been formulated corresponding sealing grade.Of a great variety.Tight grade, durable grade and three aspects of temperature grade are evaluated.
In order to improve sealability, the technical specific pressure of often taking high-precision grinding-in face, increasing sealing surface, the stiffness of raising structure.Except the structural design of valve and to make processing the most obvious to the influence that leaks outside, to the processing request strictness the most of valve rod and filler and stuffing box.1, the casting requirement is very high, does not have various casting defects.2, improve the valve rod and the roughness of stuffing box, the straightness accuracy of valve rod, the perpendicularity and the degree of finish in valve gap stuffing box hole.
Because the structure choice of valve packing letter, herein be sealed into motive sealing, valve rod rotate or sliding process in filler wear and tear easily, need select special low leakage packing seal and packing seal combination for use, the gap of strict control filler and valve rod, the gap of filler and Stuffing box.
In sum, existing valve manufacturing processing request and cost of production are higher, and working life, usability are subjected to filling material quality and medium temperature or the like factor affecting, reveal easily, need change the filler periodic maintenance.And in the existing time-delay valve, mainly adopt mechanical type or electromagnetic type time-delay structure, and two kinds of structures are all comparatively complicated, and poor stability, and working life is limited.
(3) summary of the invention: the purpose of this utility model will solve the easy wear out failure of existing time-delay class valve dynamic seal exactly, and working life is short, the requirement on machining accuracy height, and the time-delay structure complexity, problems such as manufacture cost height provide a kind of maglev type smart valve.
