Description
Technical field
The utility model relates to a kind of stop valve, particularly relates to one and is applicable to the high voltage bearing stop valve of super large caliber, is mainly used in the operating mode controlling large discharge, high-speed fluid.
Background technique
The domestic stop valve not yet having valve manufacturer can produce this super large caliber, hyperpressure at present, and chemical industry, scientific research especially the valve of military industry to this effective control high-velocity fluid rely on very much.
In order to fill up the blank of domestic valve in this field, my company's autonomous Design, have developed the valve of this model.
Model utility content
According to proposing in the prior art in background material, lacking in prior art and being a kind ofly directed to the valve effectively controlling high-velocity fluid specially, and propose one and be applicable to the high voltage bearing stop valve of super large caliber.The utility model mainly by: valve body 1, flap 2, O RunddichtringO assembly 3, valve rod 4, balance set 5, support 6, electric actuator 7, suspension ring 8, lubricating cup 9, bearing 10, Stem Mut 11, rotation-preventing mechanism 12, filler 13 etc. form, it is characterized in that, the sealing pair of valve adopts 60 ° of conical surface seal forms, easily seals; Described valve body 1, flap 2, balance set 5, valve rod 4, be the part of forging molding; Described flap 2 is provided with position-limit mechanism, deviates from flap to prevent O type circle; Described seal ring assembly 3, is arranged between flap 2 and balance set 5, adopts three road O RunddichtringO sealings altogether; Described valve rod 4 arranges rotation-preventing mechanism 12, for prevent the frictional force produced in the course of action of valve from causing valve rod to rotate, endangers the sealing pair of valve; Described balance set 5, be mainly used in the keying moment reducing valve, thus ensure, valve is balance type structure; Described suspension ring 8 for being arranged on the screw on valve body, with facilitate processing, assembling and install; Described lubricating cup 9, is arranged on support neck, convenient to bearing interpolation lubricating grease; Described bearing 10, has been arranged in Stem Mut 11 revolute pair, thus ensures that valve opening and closing is steady, reduces frictional force when opening and closing, extends the working life of Stem Mut; Described filler 13, for the upper sealing of valve, avoids the situation causing medium to leak because O type coil assembly 3 damages.
Material of main part of the present utility model adopts No. 25 steel, and described valve blank is forging molding, thus can ensure Security, the reliability of valve.
The structure of valve of the present utility model adopts straight-through balance type structure, this structure is on flap 2, arrange 2 relief holes communicated with runner, when the valve is closed, flap 2 moves downward, high-pressure medium active force is discharged in balance set 5 from relief hole, arrange O RunddichtringO assembly 3 between balance set and flap, therefore during valve closing, flap only need overcome the sealing force of sealing surface and salable.
Further, described high pressure valve, the total force medium active force on its sealing surface accounts for significant proportion, if eliminate medium active force, the keying moment of that valve will reduce greatly, thus also significantly reduces the energy waste driving valve.
The switching motion realizing valve mainly through electric actuator 7 of valve of the present utility model, this actuator can realize hand/TURP and change, when accident condition (under off-position), operator, by on-site manual opening/shutting valve, ensure that the personal safety of the reliability that valve uses and operator.
Valve of the present utility model and Electronic control part thereof are normally-off valve: electric actuator is connected, and electric actuator drives Stem Mut to rotate, the downward straight line motion of Stem Mut band ovable valve stem, and valve rod promotes flap and moves downward, valve closing.When valve rod moves downward, be connected to slide block on valve rod and valve rod is synchronized with the movement, when arriving the closed position of valve setpoint, the control signal of electric valve executing mechanism exports the analog signals of 4 ~ 20mA, simultaneously liquid crystal screen display valve closing.
The beneficial effects of the utility model are, provide a kind of simple operation, safe and reliable, be applicable to super large caliber, high voltage bearing stop valve, thus filled up the blank of domestic valve producer in this field, give chemical industry simultaneously, the use of scientific research and military industry field provides Reliable guarantee.
Accompanying drawing explanation
Fig. 1 is the structure diagram of this model utility.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model mainly by: valve body 1, flap 2, O RunddichtringO assembly 3, valve rod 4, balance set 5, support 6, electric actuator 7, suspension ring 8, lubricating cup 9, bearing 10, Stem Mut 11, rotation-preventing mechanism 12, filler 13 etc. form.
Electric actuator 7 is installed on the frame 6, and it is according to the instruction of operator, the control of opening valve or closing.When electric actuator 7 performs out code, its band ovable valve stem 4 moves downward, and the flap 2 connected with valve rod 4 also synchronously moves downward, at this moment valve body 1 inner chamber diminishes, high-pressure medium flows in balance set 5 from the relief hole flap 2, and flap 2 sealing surface is combined with valve body 1 sealing surface, valve closing.Vice versa.
The utility model mainly domesticly at present not yet designs the heavy caliber of production, the stop valve of high pressure and must from the present situation of external import to solve.Break the restriction of overseas market to Domestic Scientific Research, military project aspect.
It should be noted that, above-mentioned each technical characteristics continues combination mutually, is formed not in above-named various embodiment, is all considered as the scope that the utility model specification is recorded; Further, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
