Abstract
The utility model relates to a stop valve which can be matched with a straight stroke electric actuator and can be used in the environment of boiling water. The stop valve matched with the straight stroke electric actuator mainly comprises a valve body, a valve cover, a rubber plug, a valve rod and a spring, wherein the valve body is connected with the valve cover; the rubber plug and the valve rod are arranged between the valve body and the valve cover; the bottom of the valve rod is connected with the rubber plug; the valve rod is provided with the spring, and the other end of the spring is connected with the valve cover; the stop valve is characterized in that the valve rod is formed by fixedly connecting two parts, wherein the upper part is a plastic rod, and the lower part is a metal rod; and the surface of the metal rod is sprayed with a polytetrafluoroethylene coating. The stop valve can be used in the environment of boiling water for a long time and is not easy in scale formation, so that the service life of the stop valve is prolonged.
Description
Technical field
The utility model belongs to fluid machinery engineering automation field, relates to a kind of stop valve of joining the straight stroke electric final controlling element and can use under the boiling water environment.
Background technique
In systems such as boiling water room, all-purpose card charging type electrical water boiler, often can use electric valve (with motor, electromagnetism or other electric device operable valve), electric valve mainly contains electromagnet cut off valve, electric ball valve, Electric Actuated Stop Valves, pneumatic valve or the like, present most popular electromagnet cut off valve, easy fouling under its boiling water environment, be difficult for guaranteeing sealing, the life-span is low, and maintenance expenses is too high; Use electric ball valve, though less scaling, because it has closed time-delay, can not be used widely; Use pneumatic valve owing to want pipe arrangement and most of this class valve volume is all very big causes that expense is too high more to be difficult to practical application.
The shortcoming of prior art is: the Electric Actuated Stop Valves that uses in systems such as boiling water room, all-purpose card charging type electrical water boiler, low, the easy fouling of its life-span, the difficult assurance seal.
The model utility content
The purpose of this utility model is for overcoming deficiency of the prior art, provide a kind of simple in structure, seal reliable and less scaling stop valve of joining the straight stroke electric final controlling element, thereby makes the miniature electric stop valve become possibility under the automatic control of boiling water environment.
A kind of stop valve of joining the straight stroke electric final controlling element mainly comprises valve body, valve gap, plug, valve rod, spring; Wherein, valve body is connected with valve gap, be provided with plug and valve rod between valve body, the valve gap, stem bottom connects plug, and spring is housed on the valve rod, and the spring the other end is connected with valve gap, it is characterized in that: described valve rod forms by two-part are affixed, top is plastic bar, and the bottom is a metallic rod, metallic rod surface spray polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model: simple in structure, sealing is reliable; Can be for a long time under the boiling water environment, use and less scaling, prolonged stop valve working life.
Description of drawings
Fig. 1 is the utility model structural representation, among the figure: 1, valve body, 2, valve gap, 3, plug, 4, valve rod, 5, spring, 6, final controlling element.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of stop valve of joining the straight stroke electric final controlling element mainly comprises valve body 1, valve gap 2, plug 3, valve rod 4, spring 5; Wherein, valve body 1 is connected with valve gap 2, be provided with plug 3 and valve rod 4 between valve body, the valve gap, stem bottom connects plug, and spring is housed on the valve rod, and the spring the other end is connected with valve gap, it is characterized in that: described valve rod 4 forms by two-part are affixed, top is plastic bar, and the bottom is a metallic rod, metallic rod surface spray polytetrafluorethylecoatings coatings.
Described valve rod and plug joint, plug and valve rod have certain amount of deflection.Thereby guarantee that valve plug when closing has from the centering ability, thereby can reliable sealing.
Described plug is embedded with tinsel by rubber inside and makes, and has prolonged stop valve working life.
During use, stop valve and final controlling element 6 are combined together, and the plastic bar part of valve rod is connected with final controlling element, and final controlling element drives plastic bar and moves upward, and moves upward thereby drive plug, makes valve open; Final controlling element receives and closes valve signal when needing to close valve, and valve rod moves downward it by the potential energy of spring, throttle down.Metallic rod surface spray polytetrafluorethylecoatings coatings can prevent the metallic rod fouling, thereby guarantees the sealing of itself and Sealing.
Claims (3)
