The rotary-cut valve can ensure that precipitation and scale formation are not generated in an inner cavity.

Description

Rotating cutting valve

Affiliated technical field

But the utility model relates to the valve of interior fouling of a kind of drain body cavity and precipitation.

Background technique

Be called ball valve with spheroid as the valve of closure member, simple to operation quick because of it, be widely used in the industrial production pipelines such as chemical industry, oil, metallurgy, electric power, the energy, it is by the rotation of control spheroid, only need half-twist, within several seconds, can realize the keying of valve.But in the process that spheroid is closed or opened, medium will enter in the inner chamber of valve body, and medium is under the state of two phase flow, and precipitation, fouling cause spheroid to rotate, thereby cause whole valve invalidation in the body cavity of being everlasting, and influence the normal operation of pipeline.

Summary of the invention

In order to overcome existing ball valve causes precipitation and fouling easily at body cavity problem, the utility model provides a kind of valve, do not allow and form fouling and precipitation in the valve body, keep valve channel unimpeded effectively, thereby guarantee that pipeline normally moves, also have simultaneously with ball valve same keying characteristics are rapidly arranged.

Technical solutions of the utility model are: right valve barrel, intermediate, left valve barrel is formed shell, handle, valve rod, Gland, right valve barrel, left valve barrel connects, valve rod is inserted in the positioning hole of left valve barrel, stationary axle passes the clamping plate of both sides, flap, two ends are inserted in a left side, in the positioning hole of right valve barrel, hexagon head bolt, belleville spring, hexagon nut is made fastening piece, connecting cleat and flap, it is the structure of floating with flap position, right valve barrel, right valve seat, flap, left side valve seat, cylindrical compression spring, left valve barrel connects, a left side, a right valve seat cylindrical and a left side, the sealing of " O " shape seal ring is arranged, valve rod between right valve barrel and clamping plate, flap is done horizontal transmission with gear pair; Clamping plate are semicircular plate, and the medium channel hole is arranged at top, and fixed shaft hole is arranged at the bottom, and both sides are blind plate, and flap is a sector, and the medium channel hole is arranged at top, and the right side is a blind plate, and fixed shaft hole is arranged at the bottom, and the axis hole outside is the semi-circumference gear, also is the semi-circumference gear on the valve rod; Working principle is like this: handle with sleeve, drive valve rod, flap rotation, when the blind plate of flap is blocked valve seat through-hole, valve ends, half-twist, when the flap through hole forwards the valve seat through-hole position to, valve is conducting then, because the effect of belleville spring, and the effect of pressure spring make flap and clamping plate and left and right valve seat be in fit-state, just allow flap rotate, stop solid particle to leak the gap again, the O-ring seals sealing is arranged between valve seat and valve body, clamping plate, thereby guarantee the proper functioning of valve from flap and clamping plate, valve seat.

The beneficial effects of the utility model are, because flap opens and closes the realization that rotatablely moves, only need half-twist, can realize the keying of valve, open and close rapidly the same with ball valve; Because belleville spring is to the clamping plate elastic force, pressure spring makes clamping plate and left and right valve seat and flap be in fit-state to the elastic force of valve seat, both can allow flap rotate freely, and successfully stops solid particle to leak from the gap again; The O-ring seals sealing is arranged between valve seat and valve body, clamping plate, do not produce precipitation and fouling in the body cavity all along, valve is in steady-working state.
