Abstract
The utility model relates to a hydraulic stop valve convenient for maintenance and to the technical field of valve mechanical devices. The welded valve cover and valve body of the traditional hydraulic stop valve have welding deformation and welding stress and therefore influence the flexibility of opening and closing the valve; and the manufacturing difficulty and the processing cost are increased. The utility model provides the hydraulic stop valve convenient for maintenance, which comprises a valve body which has a cavity communicated with an inlet and an outlet, a piston rod arranged in the center of the inner cavity of the valve body, valve flap arranged at the bottom of the piston rod, and a valve cover arranged on the valve body. The hydraulic stop valve further comprises an oil cylinder, wherein the oil cylinder is fixed at the upper end of the piston rod by a detachable connecting piece. The hydraulic stop valve convenient for maintenance of the utility model has the advantages that: the oil cylinder is connected with the valve body by the detachable connecting piece; welding is unnecessary; the welding deformation and welding stress are eliminated; the flexibility of opening and closing the valve is excellent; then the oil cylinder is connected with the valve body by the connecting piece; and the preparation is simple and the production cost is low.
Description
Technical field
The utility model relates to valve class mechanical device, is specifically related to a kind of liquid operated globe valve.
Background technique
Liquid operated globe valve is widely used a kind of in the stop valve, and its flap and valve seat are normally based on the plunger principle design, and flap polishes into plunger and is connected with valve rod, and sealing is to be realized by two elastic seal rings that are enclosed within on the plunger.Two elastic seal rings separate with a collar, and by the load that is applied to by bonnet nut on the valve gap seal ring around the plunger are fastened.Elastic seal ring can be changed, and can adopt various materials to make, and this valve is mainly used in the break-make of pilot line, but has the plunger of special form or the special collar, also can be used to regulate flow.As the patent double-hemisphere stop valve, the patent No. 95111583.9, main structure comprises valve body, lower valve base, upper valve base, valve gap, flap, spool, seal washer, swingle, housing pin, handwheel and nut etc.Owing to be provided with two valve seats and two hemisphere flap, improved external sealed and interior sealing effect.In addition, on swingle, be provided with boss, be provided with seal washer below it, further strengthened the external sealed effect.Flap energy omnirange displacement or rotation have improved the sealing matching effect, have reduced relevant component processing and assembling difficulty simultaneously again.Liquid operated globe valve has simple in structure, manufacturing and easy to maintenance; Working stroke is little, and opening and closing time is short; Good airproof performance, friction is little between sealing surface, and the life-span is than advantages such as length.Its deficiency is: the common employing that is connected between existing liquid operated globe valve valve gap and the valve body is directly welded or is spirally connected, and welding exists welding deformation, welding stress, influences the flexibility of valve opening and closing; Increased manufacture difficulty and processing cost simultaneously, can not guarantee the tightness of valve body and be spirally connected.
Summary of the invention
The purpose of this utility model is to propose a kind of liquid operated globe valve of being convenient to keep in repair, and the welding that solves the prior art existence exists welding deformation, welding stress, and being spirally connected influences the flexibility of valve opening and closing and the problem of sealability.
For achieving the above object, the utility model is taked following technological scheme:
A kind of liquid operated globe valve of being convenient to keep in repair, comprise that one forms cavity and imports and exports valve body 3, the piston rod 2 that is contained in valve body 3 lumen centers that communicates, the flap 1 that is installed in piston rod 2 bottoms, be contained in the valve gap 13 above the valve body 3, also comprise oil cylinder 9, oil cylinder 9 is fixed on piston rod 2 upper ends by removable link.
Described link is detachable link, comprise flange seat 4 and double-screw bolt connecting sleeve 6, flange seat 4 is combined on the oil cylinder front cover 7 and with double-screw bolt connecting sleeve 6 and is threaded, double-screw bolt connecting sleeve 6 is socketed on the piston rod 2 and is fixed on valve body 3 tops, also is provided with dust ring 14 on removable link.
The position diameter that dust ring 14 is installed on the described removable link is 3 times of piston rod 2 diameters.
When installing in the utility model the flange seat in the link 4 is combined with the front cover 7 of oil cylinder, double-screw bolt connecting sleeve 6 in the removable link is socketed on the piston rod 2, sheathed dust ring 14 prevents the dust wearout parts on link, influences liquid operated globe valve working life.
The utility model is owing to take above technological scheme, and it has the following advantages:
1, by using the utility model, be connected by removable link between oil cylinder 9 and the valve body 3, need not weld, eliminated the welding deformation, the welding stress that weld existence, the valve opening and closing flexibility is good.
2, dust ring is set on link, has guaranteed the stability of liquid operated globe valve, good seal performance.
3, the utility model is connected with valve body oil cylinder by link, also has preparation simply, the beneficial effect that cost of production is lower.
