Embodiment
Numerous case display, the external pattern of harmful influence storage tank vent control valve door, be the source of the hidden danger of accidental release, taking place frequently of similar accident is hard to guard against, and accident types majority belongs to the damage of control valve and unexpected inefficacy, and the case of storage tank body cracking is few.Obviously, control valve and risk of leakage closely related, if we install one safety valve again additional in the respective channel of tank inside just can tackle the fault of external valve and unexpected damage, thus accomplish that precautions averts perils.According to structure and the production technology of storage tank, the safety valve on its inner passage must possess simple structure and certainly open function, once external valve inefficacy out of control, internal security valve just can quick closedown passage accurately, then reaches the object of urgent danger prevention.The technological scheme that the utility model is studied based on this just.
In order to make the technical solution of the utility model more easily be understood, below in conjunction with drawings and Examples, it is described in detail.
See Fig. 1, just logical bankruptcy type storage tank of the present utility model, its structure comprises storage tank body 4, base 5 is equipped with in the bottom of described storage tank body 4, guard shield 6 is equipped with on the top of described storage tank body 4, described guard shield 6 is built with external control valve 2 and the control valve handle 1 connecting described external control valve 2, and the built-in gravity safety valve 3 connecting external control valve 2 is equipped with in the inside of described storage tank body 4.
With reference to Fig. 2, described built-in gravity safety valve 3, comprise valve body 31 and be threaded in the housing 310 of described valve body 31 bottom, described housing 310 has first fluid medium channel 39, described valve body 31 has second fluid medium channel 311 and the 3rd fluid medium channel 312, conical seal (contact) face 32 is processed in the lower end of described 3rd fluid medium channel 312, the lower inner that described housing 310 is positioned at first fluid medium channel 39 is provided with dunnage 38, the ball-type concave surface in described dunnage 38 center portion is provided with univesal sphere 35, the top fixed installation spherical support holder 34 of described univesal sphere 35, described spherical support holder 34 is provided with the sphere core 33 agreed with mutually with the internal surface of described conical seal (contact) face 32, the bottom of described ball-type concave surface is connected with stiff shaft 36, the lower end of described stiff shaft 36 connects balance weight body 37.
Under normal circumstances, sphere core 33 in described built-in gravity safety valve 3 is positioned at immediately below described conical seal (contact) face 32, and sink to down in described spherical support holder 34 under gravity, thus keep compressing with the minimum point of described spherical support holder 34 state contacted immediately below it; Described univesal sphere 35 is matched with the ball-type concave surface in described dunnage 38 center portion and is formed universal loose joint.
Shown in Fig. 1 is the normal posture just leading to bankruptcy type storage tank of the present utility model, now, the inner passage of described built-in gravity safety valve 3 is in opening state, ball valve core 33 namely in described built-in gravity safety valve 3 is in separated state with described conical seal (contact) face 32, flowing medium enters described housing 310 by first fluid medium channel 39, and the open channel between described ball valve core 33 and conical seal (contact) face 32 flow into described in valve body 31 in, the open channel of storage tank external control valve 2 is arrived by outer defeated release again by second fluid medium channel 311 or the 3rd fluid medium channel 312.
When described just logical bankruptcy type storage tank because certain reason occur to be inverted and external control valve 2 lost efficacy situation time; ball valve core 33 in described built-in gravity safety valve 3 will be pressed on described conical seal (contact) face 32 under the effect of itself gravity; thus close its inner passage; the high-pressure medium of tank inside is stoped to flow out; for the valve invalidation of storage tank outside provides protection, reach the object of urgent danger prevention.
Depart from forward stand up position when described just logical bankruptcy type storage tank and tilt situation time, the center of the balance weight body 37 in described built-in gravity safety valve 3 also can offset thereupon, gravitational moment is formed to the strong point that univesal sphere 35 contacts with dunnage 38 center portion ball-type concave surface, thus keep the stiff shaft 36 be connected with described ball-type concave bottom to be still in erectility, with the gravity characteristic of its " tumbler ", the spherical support holder 34 on described univesal sphere 35 top and described stiff shaft 36 are synchronously deflected, and lifting effect is lifted to the generation of described ball valve core 33, reduce the area of passage of open channel between described ball valve core 33 and described conical seal (contact) face 32 gradually, enter the process status reducing flow.Along with the increase of deflection angle, the deflecting torque that described balance weight body 37 produces can continue to increase, and described ball valve core 33 also will be continued to lift lifting, compresses the passage of closing between itself and described conical seal (contact) face 32 until final, blocks medium and passes through.
In the utility model, in described built-in gravity safety valve 3, the power of ball valve core 33 closing passage places one's entire reliance upon the gravitational potential energy of itself, without the need to any control of outside, meet the design concept of storage tank essential safety, and gravity pure natural green power especially, it does not rely on the feature of any energy to be that storage tank built-in relief valve creates sufficient condition.The built-in gravity safety valve 3 be installed in storage tank belongs to non-maintaining device; not only there is the advantages such as flexible movements, accurate, stable, reliable, non-maintaining, Non-energy-consumption; and its gravitational potential energy also lays in the emergency preplan eliminated safe hidden trouble, numerous harmful influence storage tank deposit hedging can be become, promote the one preferred technique of essential safety level.
Above with reference to drawings and Examples, schematically describe the technical solution of the utility model, this description is not restricted.Those skilled in the art will be understood that in actual applications, and in the utility model, some change all likely occurs the details that arranges of all parts, and other staff also may make similar Design under its enlightenment.Special needs to be pointed out is: only otherwise depart from design aim of the present utility model, all apparent variations in detail or similar Design, be all included within protection domain of the present utility model.
