Abstract
The utility model discloses an all-welded fixed ball valve with a cylindrical body. The all-welded fixed ball valve comprises the valve body, valve seats, a valve stem, a ball and bonnets. A lining plate is cushioned between the valve body and the ball, a coil spring is arranged between each bonnet and the corresponding valve seat, a packing case and a valve neck are arranged between the valve stem and the valve body, a first thrust bearing, a packing gland and a packing bushing are arranged between the valve neck and the ball, the valve stem is connected with the packing case and an extension pipe connecting disc, a connecting shaft sleeve, a second thrust bearing and a gland are arranged in the extension pipe connecting disc, a turbine head is mounted on the upper portion of the extension pipe connecting disc, a driving connecting disc and an upper valve stem are arranged between the extension pipe connecting disc and the turbine head, O-shaped rings are cushioned among the valve seats and the ball, the bonnets are fixedly connected with the valve body by screws, and the valve neck and the ball are fixed by the aid of nuts, studs and hinge pins. The all-welded fixed ball valve has the advantages that the all-welded fixed ball valve is simple in structure, good in sealing effect, simple in operation and convenient to use, and the production cost and waste are reduced.
Description
Technical field
The utility model relates to the ball valve technical field, relates in particular to a kind of cylindrical body and welds Fixed ball valve entirely.
Background technique
At present, in existing oil, natural gas, chemical industry used ball-valve structure complicated, will raise the cost like this, and difficulty also can increase greatly in the process of assembling, will waste time and energy like this, next is poor sealing performance in the process of using, maintenance difficulty is big, has reduced working life.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of cylindrical body to weld Fixed ball valve entirely.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of cylindrical body welds Fixed ball valve entirely, comprise valve body, valve seat, valve rod, spheroid and valve gap, be lined with liner plate between about valve body and the spheroid, be provided with helical spring between valve gap and the valve seat, helical spring mounts elastically, be provided with Stuffing box and valve neck between valve rod and the valve body, be provided with first thrust-bearing between valve neck and the spheroid, Gland and filler gland, valve rod bonding pad case and extension pipe land, the connecting shaft cover is housed in the extension pipe land, second thrust-bearing and gland, extension pipe land top is equipped with a turbine head, is provided with between extension pipe land and the turbine head to drive land and upper valve rod.
Be lined with O type circle between described valve seat and the spheroid.
Described valve gap is fixedlyed connected by screw with valve body.
Described valve neck and spheroid are fixed by nut, stud bolt and bearing pin.
The beneficial effects of the utility model: this model utility is simple in structure, has reduced cost of production, has improved benefit; Good sealing effect is avoided revealing and is leaked, and has reduced waste, has protected environment; Simple to operate, keep in repair more conveniently, improved its working life.
