Abstract
The utility model discloses a hydraulic hemisphere back valve comprising a hydraulic controller and a hydraulic cylinder connected with the hydraulic controller. A piston of the hydraulic cylinder is hinged with a connecting rod whose other end is connected with a valve spindle of an eccentric half ball valve. The valve body or the valve cover of the eccentric half ball valve is connected with a bracket hinged with the hydraulic cylinder. An eccentric center hemisphere core, in particular an eccentric center valve core with complete flow-channel being adopted as the valve core of the back valve, the utility model is provided with little head loss, low operation cost, reliable sealing in the self-sealing mode, long service life and mud resistant that the mud is prevented from entering between the spindle and the spindle sleeve without mud abrasion, and is suitable for the ductwork of clean-water, raw-water, sewage-water, sea-water, coal gas, natural gas, oil system, etc, shearing inclusions especially in the raw-water and the sewage-water to guarantee the sealing under any conditions.
Description
Technical field
The utility model belongs to the pipe network control valve, is specifically related to the safety check that a kind of hydrauliccontrol non-return valve, particularly spool are hemisphere.
Background technique
The spool of widely used safety check all is valve board structures in the market, generally adopt butterfly valve for bigbore safety check, this valve is in the water system that has silt to exist, the valve plate of butterfly valve in runner by silt underwashing, after the valve plate of butterfly valve is opened simultaneously, valve plate takies flow channel space, causes the runner loss of head.
Summary of the invention
It is the safety check of the hydraulic control of hemisphere that the purpose of this utility model is to provide a kind of spool, to overcome the problem that above-mentioned safety check exists.
The technical solution of the utility model is: hydraulic control non-return semispherical valve comprises hydraulic control device, the oil hydraulic cylinder that hydraulic control device connects, the piston hinge connecting rod of oil hydraulic cylinder, the other end of connecting rod connects the valve shaft of eccentric half-ball valve, connect support on the valve body of eccentric half-ball valve or the valve gap, oil hydraulic cylinder and support are articulated and connected.
The spool of this safety check adopts the eccentric semi-spherical core, can adopt full runner eccentric semi-spherical spool especially, and it is little that it has loss of head, and operating cost is low; Adopt the selfsealings mode, sealing is reliable; Long service life; Anti-silt, no silt enters no sand erosion between axle and the axle sleeve; Be applicable to pipe networks such as clear water, Yuan Shui, sewage, seawater, coal gas, rock gas, oil system, especially in Yuan Shui, sewage, can play shear action, thereby guarantee the sealing under any situation foreign material.
