Description
Technical field
The present invention relates to a kind of Bellows valve.
Background technique
Extensively leak at present in the valve regular meeting of industrial uses such as chemistry, pharmacy, oil, phenomenon such as gas leakage.The reason that causes, mainly be because present valve adopts different fillers to seal, and filler hugs valve rod, when starting valve rod, valve rod and filler generation frictional heating, in the course of time, sealing surface is damaged, cause leak, the generation of gas leak phenomenon, Another reason is that the medium in the valve generally all has corrosivity, valve rod is immersed in for a long time in the medium and produces corrosion and fouling, makes that sealing surface damages between valve rod and filler, cause leak, the generation of gas leak phenomenon.The valve that adopts the sylphon seal structure is arranged at this shortcoming, for example Chinese utility model patent CN2551821Y, open day is on May 21st, 2003, a kind of bellows stop valve is disclosed, this valve is mainly by valve body, valve gap, flap, valve rod, filler, parts such as bellows component and handwheel constitute, valve gap is installed on the valve body, flap be contained in valve rod the lower end and with the contact seal of valve body honeybee face, filler is contained between valve gap top and the valve rod, handwheel is contained in the upper end of valve rod, bellows component is contained on the valve rod of body cavity and with its sealing, because valve rod is provided with bellows component, medium in valve rod and filler contact-segment and the valve is kept apart fully, solved preferably owing to sealing surface between valve rod and filler damages the shortcoming that causes the seepage phenomenon.But the metal bellows of this valve can't bear high-pressure medium, makes this valve can't be used in high-pressure medium.
Summary of the invention
The purpose of this invention is to provide a kind of Bellows valve that is used in high-pressure medium.
To achieve these goals, the present invention adopts following technical solution: a kind of Bellows valve, comprise valve rod, valve body, valve gap, bellows, bellows is around the valve rod setting, and the upper end of this bellows is fixed on the valve gap, the lower end is fixed on the valve rod, cavity is marked with equilibrium liquid between bellows and the valve rod, is fixed with reservoir on the valve rod, and valve rod is provided with intercommunicating pore, one end of intercommunicating pore communicates with reservoir, and the other end of intercommunicating pore communicates with cavity between bellows and the valve rod.
Because in the above-mentioned technical solution, cavity is marked with equilibrium liquid between bellows and the valve rod, can guarantee the balance of bellows external and internal pressure, can avoid the destruction of high-pressure medium to bellows, makes Bellows valve can be used in high-pressure medium.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the general structure schematic representation of Bellows valve of the present invention.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Embodiment
As shown in Figure 1, first kind of embodiment's Bellows valve of the present invention, comprise valve rod 1, valve body 3, valve gap 2, wherein be provided with metal bellows 4 between valve rod 1 and the valve gap 2, one end of metal bellows 4 welds mutually with valve gap 2, the other end welds mutually with valve rod 1, cavity is marked with equilibrium liquid 5 between metal bellows 4 and the valve rod 1, be fixed with reservoir 7 on the valve rod 1, valve rod 1 is provided with intercommunicating pore 8, one end of intercommunicating pore 8 communicates with reservoir 7, and the other end of intercommunicating pore 8 communicates with cavity between metal bellows 4 and the valve rod 1.Its working principle is: when valve starts when doing by closing, valve rod 1 moves from bottom to top, and metal bellows 4 axially slowly shrinks, when contraction makes equilibrium liquid 5 produce certain pressure, metal bellows 4 inner equilibrium liquid 5 flow to reservoir 7, have guaranteed the balance of metal bellows 4 external and internal pressures; Otherwise, when valve by reaching when closing action, valve rod 1 moves from top to bottom, metal bellows 4 axially slowly stretches, cavity increases between metal bellows 4 and the valve rod, equilibrium liquid 5 pressure reduce, and reservoir 7 inner equilibrium liquid 5 cavity between metal bellows 4 and valve rod 1 is filled, and has guaranteed the balance of metal bellows 4 external and internal pressures.
As Fig. 1, shown in Figure 2, second kind of embodiment's Bellows valve of the present invention, comprise valve rod 1, valve body 3, valve gap 2, wherein be provided with flexible bellow 4 between valve rod 1 and the valve gap 2, one end of flexible bellow 4 is enclosed within on the valve gap 2, by 16 fixed seal connections of first adapter sleeve, the other end is enclosed within on the valve rod 1, by 6 fixed seal connections of second adapter sleeve, cavity is marked with equilibrium liquid 5 between flexible bellow 4 and the valve rod 1, is fixed with reservoir 7 on the valve rod 1, and valve rod 1 is provided with intercommunicating pore 8, one end of intercommunicating pore 8 communicates with reservoir 7, and the other end of intercommunicating pore 8 communicates with cavity between flexible bellow 4 and the valve rod 1.Its working principle is: when valve starts when doing by closing, valve rod 1 moves from bottom to top, and flexible bellow 4 axially slowly shrinks, radially slowly outer rising, when outside rise when producing certain tension force, flexible bellow 4 inner equilibrium liquid 5 flow to reservoir 7, have guaranteed the balance of flexible bellow 4 external and internal pressures; Otherwise, when valve by reaching when closing action, valve rod 1 moves from top to bottom, flexible bellow 4 axially slowly stretches, radially slowly shrink, when producing certain tension force when stretching, reservoir 7 inner equilibrium liquid 5 cavity between flexible bellow 4 and valve rod 1 is filled, and has guaranteed the balance of flexible bellow 4 external and internal pressures.
