Description
Technical field
The utility model relates to a kind of stop valve, specifically a kind of balanced type pneumatic stop valve.
Background technique
Pneumatic stopping valve is industrial widely used a kind of valve, and it is mainly used in the conveying and the control of fluid.Existing pneumatic stopping valve major advantage is to realize telecontrol, is fit to the big production of modernization.At present to have defective is complex structure to the pneumatic stopping valve that uses, damage easily, keep and repair inconvenience, cylinder piston bottom and cylinder piston deploy and easily go here and there water, and lack working life.As notice of authorization day is on March 12nd, 2003, notice of authorization number to disclose a kind of Internal Balanced Pneumatic Valve for the utility model patent of CN2539885Y, the pneumatic stopping valve of this structure adopts spring structure, though it has the advantage of good seal performance, but its spring structure is very easy to damage, and valve body and cylinder go here and there water easily, needs after the damage entire cylinder is taken apart, changes spring, its maintenance is very inconvenient, and working life is also very short.Therefore inventing a kind of novel pneumatic stopping valve is highly profitable.
The model utility content
Goal of the invention of the present utility model is exactly the defective that exists at existing product, provides a kind of Internal Balanced Pneumatic Valve, to remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises valve body, is contained in the valve gap on the valve body and is contained in cylinder on the valve gap, it is characterized in that: tighten with fastening screw trip bolt after connecting flap, sealing gasket and following gland the cylinder axis bottom, cylinder axis top connects piston, piston is tightened by tightening nut, and has positioning screwn to fix.
Described valve gap passes through bolt after being fixed on the valve body and being compressed by cylinder; Described cylinder axis lower end is provided with axial weep hole; Ring tank and outer shroud tank in described valve gap is provided with; The connection part of described cylinder and valve gap is provided with weep hole; Axial and transverse row water hole, described cylinder axis underpart.
The utlity model has simple in structurely, easily manufactured, be convenient to maintenance, the advantage of long service life, it utilizes source of the gas control and source of the gas to drive, built-in balance sysmte, sealing is reliable, utilizes two-position-five-way solenoid valve energy telecontrol.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, valve body 1 is connected with cylinder 11 usefulness bolts 20 by valve gap 7 location; Cylinder 11 is provided with into and out of two air source holes and draining (gas) hole φ, and cylinder axis 19 bottoms connect flap 5, sealing gasket 4 and following gland 2 usefulness fastening screw trip bolts 3 and tighten; Cylinder axis 19 tops connect piston 14, tighten by tightening nut 16, when source of the gas when gas is gone on cylinder 11 tops, under the effect of O RunddichtringO 6,8,9,10,12,13,17,18,22, piston 14 drives cylinder axis and moves down, to making sealing gasket 4 and valve body 1 sealing surface closure, the realization fluid dams, otherwise source of the gas is gone into gas from cylinder 11 lower ends, and piston 14 drives cylinder axis 19 and moves up, to sealing gasket and valve body 1 sealing surface are disconnected, realize that fluid is open-minded.
As Fig. 2; shown in Figure 3; in order to prevent valve body 1 and cylinder 11 string water (gas); ring tank 15 and outer shroud tank 24 in described valve gap is provided with; outer shroud tank 24 is provided with transverse row water hole 23; axial and transverse drainage (gas) hole 25 and 26, cylinder axis 19 underparts; set up draining (gas) hole φ at the cylinder 11 and the connection part of valve gap 7 simultaneously; when cylinder axis 19 moves upward; O RunddichtringO 22 and 18 will be with the surplus water (gas) of cylinder axis lower end; draining (gas) orifice flow goes out from the cylinder 11; protect other pneumatic element that is installed in the valve outside, thereby increased the working life of valve.The utility model utilizes source of the gas control and source of the gas to drive, built-in balance sysmte, and sealing is reliable, utilizes two-position-five-way solenoid valve energy telecontrol.Valve can be in Chang Kai or Normally closed type.
