Abstract
The utility model relates to a two-way spiral chute ball valve without no abrasion, which is composed of a valve body, a valve cap, a handwheel, and a control end. A valve seat and a ball body with a through hole are arranged inside the valve body. The control end of the utility model comprises a bushing and a clamping ring arranged at the lower part inside the valve cap. A valve rod is arranged in the middle. A sealing gasket, a clamping ring, and a laminated shim are arranged between the valve rod and the valve cap. The upper pat of the valve cap is provided with a supporting seat. The upper part of the supporting seat is provided with a thread sleeve for the handwheel, which is matched with the handwheel. The upper end of the valve rod is connected with the thread sleeve for the handwheel. The lower end of the valve rod is provided with a slope deflective section, a spiral deflective section, and a straight deflective section. The lower end of the valve rod is inserted inside a neck cavity of the ball body, and the valve rod is matched with a pin column arranged inside the cavity.
Description
The utility model relates to a kind of bidirectional screw chute that is used for industries such as oil, chemical industry, electric power, metallurgy, papermaking does not have the wearing and tearing ball valve.
Traditional O 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 be to provide a kind of nothing deposit medium, double fluid to, do not have wearing and tearing, torque force is little, keyings is rapid, operate light bidirectional screw chute does not have the wearing and tearing ball valve.
The purpose of this utility model is achieved in that a kind of bidirectional screw chute does not have the wearing and tearing ball valve, it is by valve body, valve gap above the valve body, handwheel and control end constitute, valve seat and through hole spheroid are housed in the valve body chamber, it is characterized in that control end comprises by bottom in the valve gap is equipped with lining and collar, valve rod is equipped with in the centre, be provided with the sealing gasket assembly between valve rod and the valve gap, trim ring and spacer, the bearing that is equipped with valve gap top matches, bearing top is provided with the handwheel swivel nut, liner, gland and set screw, be embedded with flat key between handwheel swivel nut and the handwheel, and by gland, bolton, the valve rod upper end portion is connected with the handwheel swivel nut, the valve rod intermediate portion is provided with straight type chute, be embedded with ball between chute and the lining, the valve rod underpart is provided with tiltedly section partially, spiral is section and straight section partially partially, and the valve rod underpart is inserted in the neck chamber, through hole spheroid top with the pin that is provided with in the chamber and matched, and the centre of location of protruding terminus and valve body is complementary under the spheroid.Its working principle is as follows: when stirring handwheel and clockwise rotate, coupled valve rod is done downward movement, because of being subjected to the control of chute and ball, valve rod can only can not rotatablely move by moving linearly, the wedge power of the descending generation of valve rod makes spheroid be close to valve seat, when the pin in the neck chamber, spheroid top is in the tiltedly inclined to one side section of valve rod lower end, locks spheroid and valve seat fully, cut off the medium two-way flow, be closed state; When handwheel rotates counterclockwise, valve rod moves upward, and drives spheroid that the lower end links to each other and breaks away from valve seat and produce certain clearance, when valve rod continues when up, two pins in the neck chamber, spheroid top are subjected to the valve rod underpart spiral twisting force of section partially, force the through hole spheroid under disengaging valve seat situation, to turn 90 degrees certainly, can not produce wearing and tearing, when the up termination of valve rod, pin is in the straight section partially of valve rod lower end, the spheroid through hole is consistent with valve hole, is opening state, media flow.
The utility model modern design, compact structure, nothing wearing and tearing, nothing are deposited medium, keying is rapid, operation is light, has use value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is a valve rod of the present utility model underpart schematic representation.
Shown in Fig. 1-2, a kind of bidirectional screw chute does not have the wearing and tearing ball valve, it is by valve body (2), valve gap above the valve body (4), handwheel (11) and control end constitute, valve seat (13) and through hole spheroid (12) are housed in valve body (2) chamber, its control end comprises by the interior bottom of valve gap (4) lining (17) and collar (14) is housed, valve rod (6) is equipped with in the centre, be provided with sealing gasket assembly (18) between valve rod (6) and the valve gap (4), trim ring (7) and spacer (9), the bearing (8) that is equipped with valve gap (4) top matches, bearing (8) top is provided with handwheel swivel nut (9), liner (20), gland (21) and set screw (22), be embedded with flat key (23) between handwheel swivel nut (9) and the handwheel (11), and by gland (24), bolt (10) is fastening, valve rod (6) upper end portion is connected with handwheel swivel nut (9), valve rod (6) intermediate portion is provided with straight type chute (25), be embedded with ball (5) between chute (25) and the lining (17), valve rod (6) underpart is provided with tiltedly section (28) partially, spiral is section (29) and straight section (30) partially partially, valve rod (6) underpart is inserted neck chamber, through hole spheroid (12) top (26) pin (3) interior and that the chamber is provided with and is matched, and protruding terminus (27) is complementary with the centre of location (1) of valve body (2) under the spheroid (12).
