Abstract
The utility model relates to a double-way non-abrasion hard sealing ball valve which is composed of a valve body, a valve cover and a controlling end, wherein a valve base and a ball body with a through hole are arranged in the valve body; the controlling end is assembled in the mode that the inner lower part of the valve cover is provided with a supporting base, the middle part is provided with a valve rod, and a bearing, a pressing sleeve, a soft sealing component, a hard sealing component, an oil filling nozzle, etc. are arranged between the valve cover and the valve rod. The upper side of the valve cover has a hand wheel connected with the top end of the valve rod. The outer side of the supporting base is provided with a sliding slot and a positioning screw. A cylinder pin shaft contacted with an inclined post on the upper part of the ball body is arranged in the lower end of the supporting base. The lower end of the valve rod and the supporting base are matched by a spiral buckle. The utility model has the advantages of compact structure, reliable seal, double flow directions, abrasion resistance, convenient operation, high temperature resistance and high pressure resistance.
Description
The utility model relates to a kind of two-way wear-less hard seal ball valve that is used for industries such as oil, chemical industry, electric power, metallurgy, papermaking.
Zero traditional type cuts off ball valve, and the ball core rubs with valve seat in rotation process, and serious wear easily causes leakage.Simultaneously, ball core driving torque power is big, and the operation effort is time-consuming, and keying speed is slow, has influenced usability.
The purpose of this utility model is to provide a kind of does not have medium, do not have wearing and tearing, do not have leak, double fluid to, torque force is little, keyings is rapid, operate gently obstruct, the two-way wear-less hard seal ball valve of high temperature high voltage resistant.
The purpose of this utility model is achieved in that a kind of two-way wear-less hard seal ball valve, it is by valve body, valve gap and control end constitute, valve seat and through hole spheroid are housed in the valve body, it is characterized in that control end comprises by bottom in the valve gap is equipped with supporting base, the bearing that is equipped with between valve rod and valve gap and the valve rod is equipped with in the centre, gland, soft seal, hard sealing gasket, pump nozzles etc. are assembled into, handwheel is housed above the valve gap to be connected with valve stem tip portion, the joint is embedded with flat key, the supporting base outside is provided with chute and set screw, be provided with cylindrical pin in the supporting base underpart and contact with the tiltedly inclined to one side post on spheroid top, the valve rod underpart is buckled by spiral shell with supporting base and is matched.Its working principle is as follows: when rotating handwheel, coupled valve rod is along with rotation, rotation along with valve rod, the supporting base that cooperates with its spiral shell button is below done up or motion down, be subjected to the chute in the outside and the control of set screw, can only spacing half-twist, when supporting base is up, by supporting base underpart cylindrical pin and the tiltedly slip of post partially of spheroid top, produce a kind of wedge power, force spheroid and valve seat to break away from, the spheroid startup turns to 90 °, be spheroid through hole when consistent, be opening state, media flow with the pipe diameter direction; When supporting base was descending, at first 90 ° of back continuation that reset of spinning ball were descending, owing to be subjected to the tiltedly effect of post partially on spheroid top, make cylindrical pin produce another kind of wedge power, force spheroid and valve seat closure, are closed condition, cut off media flow.
The utility model compact structure, sealing are reliable, no medium, do not have wearing and tearing, open and close rapidly, operation is light, double-current to, high temperature high voltage resistant, have use value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail
Fig. 1 is a structural representation of the present utility model
As shown in Figure 1, a kind of two-way wear-less hard seal ball valve, it is by valve body (1), valve gap (2) and control end constitute, valve seat (3) and through hole spheroid (4) are housed in the valve body (1), its control end comprises by the interior bottom of valve gap (2) supporting base (5) is housed, the centre is equipped with between valve rod (6) and valve gap (2) and the valve rod (6) bearing (7) is housed, gland (8), soft seal (9,10,11), hard sealing gasket (12), pump nozzle (13) etc. is assembled into, handwheel (14) is housed above the valve gap (2) to be connected with valve rod (6) tip portion, the joint is embedded with flat key (15), supporting base (5) outside is provided with chute (16) and set screw (17), be provided with cylindrical pin (18) in supporting base (5) underpart and contact with the tiltedly inclined to one side post (19) on spheroid (4) top, valve rod (6) underpart is buckled by spiral shell with supporting base (5) and is matched.
