Abstract
The utility model discloses a metal sealing straight-through ball valve. Compressed gas enters a cylinder through a reducing valve and an electromagnetic valve in sequence; the cylinder is connected with a connecting shaft, clamp splices and a valve rod in sequence; the valve rod is rotatably connected with a sphere arranged in the middle runner of a valve body; the lower end of the sphere and a valve seat at the bottom part of the valve body are hermetically connected through a metal sealing ring. The straight-through ball valve disclosed by the utility model is controlled by the electromagnetic valve, so that the straight-through ball valve has the advantages that the action is flexible, the open and close torque is small, the sealing property is excellent and the service life is long.
Description
Technical field
The utility model relates to the through-type ball valve of a kind of metal sealing.
Background technique
At present, it is all to adopt pneumatic valve directly to drive work that conventional ball valve adopts, and it move underaction, and keying moment is large.And spheroid two ends fix to clamp sealing with a valve seat respectively, and while causing valve opening, torsion is large, adopt filler pressing sleeve to oppress by force filler and make valve stem seal, filler is fragile like this, and spheroid groove employing arc groove, sealing effect is poor, and in groove, easily has residual difficult cleaning of material.
Summary of the invention
The utility model object is that the defect existing for prior art provides a kind of metal sealing through-type ball valve.
The utility model for achieving the above object, adopt following technological scheme: the through-type ball valve of metal sealing, pressurized gas enters cylinder by reduction valve, solenoid valve successively, described cylinder is connected by coupling shaft, fixture block and valve rod successively, described valve rod is rotationally connected with the spheroid being arranged in the runner of valve body middle part, between the lower end of described spheroid and the valve seat of valve body bottom, by metallic packing ring, is tightly connected.
Further, on described cylinder, be provided with limit switch.
The beneficial effects of the utility model: through-type ball valve of the present utility model is by electromagnetic valve, and its flexible movements, open and close moment little; And sealability is excellent, long service life.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
Shown in Fig. 1, for the through-type ball valve of a kind of metal sealing, pressurized gas enters cylinder 3 by reduction valve 2, solenoid valve 4 successively, described cylinder 3 is connected with coupling shaft 5, fixture block 6 and valve rod 7 successively, described valve rod 7 is rotationally connected with the spheroid 8 being arranged in the runner 9 of valve body middle part, between the lower end of described spheroid 8 and the valve seat 10 of valve body bottom, by metallic packing ring 11, is tightly connected.
During work, solenoid valve 4 excitations obtain electric, and pressurized gas enters cylinder 3 by reduction valve 2 through solenoid valve 4, and the pressurized gas in cylinder 3 promotes the inner carrier in cylinder 3, and drive coupling shaft 5 by this inner carrier, and coupling shaft 5 is to be connected by fixture block 6 with valve rod 7.By valve rod 7, reverse with the spheroid 8 in moving valve and do corresponding action.Between spheroid 8 and valve seat 10, adopt metallic packing ring 11 sealings, can guarantee that medium cuts off from valve seat 10.Realize cutting function and UNICOM's function of convection cell.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. the through-type ball valve of metal sealing, it is characterized in that, comprise the reduction valve, solenoid valve and the cylinder that connect successively, described cylinder is connected by coupling shaft, fixture block and valve rod successively, described valve rod is rotationally connected with the spheroid being arranged in the runner of valve body middle part, between the lower end of described spheroid and the valve seat of valve body bottom, by metallic packing ring, is tightly connected.
2. the through-type ball valve of metal sealing as claimed in claim 1, is characterized in that, on described cylinder, is provided with limit switch.
