A kind of good knife gate valve of wear-resisting property
Technical field
The utility model relates to a kind of knife gate valve more particularly to a kind of knife gate valves with good wear-resisting property.
Background technique
The opening and closing element that gate valve refers to is the block valve of flashboard, and the direction of motion and flow direction of flashboard are perpendicular.Although Traditional gate valve can fully open channel, and medium is avoided to be obstructed, but since traditional gate valve volume is big, be not suitable for being mounted on High-altitude or small working space, therefore its requirement to place and object is relatively high.And traditional gate valve be not suitable for being loaded with it is dry The fluid media (medium) of powder or particulate matter.
Knife gate valve is also known as knife door lock valve, blade type Parallel Slide Valves, its opening and closing element is flashboard, the direction of motion and fluid of flashboard Direction is perpendicular, and the flashboard of knife gate valve has shearing function, can scrape the adhesion on sealing surface, remove sundries automatically, stainless Steel flashboard can prevent from corroding caused seal leakage.The working principle of knife gate valve is: manually-operated gate hand rotates handwheel, makes valve rod Up and down open to drive flashboard to move up and down, close valve, be rotated clockwise, and flashboard decline, valve is closed, It rotates counterclockwise, flashboard rises, valve opening.
Knife gate valve is that plate valve plate is changed to knife type valve plate on the basis of common gate valve.It is drawn by the screw position of valve rod Point, knife gate valve can be divided into two kinds of rising stem (RS.) knife gate valve and dark bar knife gate valve.So-called dark bar knife gate valve refers to when rotating handwheel, valve rod Rotation drives valve plate to move up and down, but valve rod does not extend outwardly.
Summary of the invention
In order to solve the deficiencies in the prior art, the purpose of the utility model is to provide a kind of good disconnecting links of wear-resisting property Valve.
A kind of good knife gate valve of wear-resisting property, including valve body, valve body is interior to be equipped with valve opening, and valve body upper end is equipped with support plate, Support plate is equipped with bracket, is equipped with valve rod in the support plate;The valve rod is connect with bracket by threads turn;The valve rod Upper end be equipped with parallel handwheel, the lower end of the valve rod is connected with rotating turret, and rotatably connect with valve rod, described turn Moving frame is equipped with groove, and valve plate protrudes into the groove inner end of rotating turret, and is fixed by pin shaft and matched nut, the valve body Upper end is equipped with through-hole, and one end of gland is installed in through-hole, and the valve plate telescopically passes through gland and protrudes into valve Hole lower end.
The lower end of the valve body is equipped with lower cover, and the lower cover is fixedly connected with the valve body by hex bolts.
It is equipped with O-ring seal in the gland, is placed in valve plate two sides.
It is additionally provided with packing in the gland, is placed in valve plate two sides.
The lower cover is equipped with lower end lid gasket.
The inner wall of the valve opening is equipped with gum cover.
The support plate is fixedly connected with the valve body by the first stud.
The gland is fixedly connected with the valve body by the second stud.
The good knife gate valve of a kind of wear-resisting property described in the utility model, the beneficial effect is that:
(1) thickness of valve body can be designed according to different pressure, so that overcoming traditional knife gate valve is not suitable with high pressure The shortcomings that with high temperature difference working environment;
(2) has the advantages that small in size, flow resistance is small, light-weight, easy to install, quick detachable, and not by high pressure and high temperature The limitation of the operating condition of difference, has wide range of applications;
(3) gland can be in close contact with valve plate, to enhance the compactness of valve body, mainly as adjusting and the dress that shuts off It sets, can be widely applied on the fluid lines such as various application systems, and gum cover set by lower end can further enhance valve opening Sealing performance.
