Abstract
The utility model relates to a gate valve of a ceramic slab with a guide hole, comprising a valve seat, a valve plate, a valve rod, the guide hole and a handle, wherein a fluid inlet and a fluid outlet are arranged inside the valve body, a gate disc is arranged between the fluid inlet and the fluid outlet, the guide hole is arranged below the gate disc, the valve rod is connected at the upper end of the gate disc, the handle is arranged at the upper end of the valve rod, the valve seat is arranged inside the valve body, a ceramic sealing ring is arranged on the valve seat, the gate disc is sandwiched in the ceramic plate and is arranged on a contact sealing surface of the gate disc and the valve seat. In the utility model, the sealing effect of the valve is improved, the service life of the valve is prolonged, the maintenance cost of the valve is reduced and the production efficiency is improved.
Description
Technical field
The utility model belongs to a kind of valve field, particularly a kind of band pod apertures earthenware slab gate valve.
Background technique
In industries such as oil, chemical industry, be specially adapted to the high oil field water injection system at present, the normal band pod apertures plate valve that uses; The sealing of existing gate valve mainly is the sealing pair at flashboard and valve base chamber, and existing sealing pair has harder sealing pair and soft seal secondary, firmly sealing pair be at the valve seat fluid import, the outlet port is inlayed with metallic material or built-up welding forms; Use in this medium that is sealed in cinder, lime-ash and slag-water slurry; Do not resist and wash away, not wear-resistant, its sealing surface damages easily; The reparation difficulty is big, is not easy to change and maintenance; In addition, the coefficient of thermal expansion and contraction of the hard sealing pair that metallic material is processed is bigger, when running into than hot fluid; Flashboard can expand with hard sealing pair simultaneously, causes flashboard stuck in valve seat, opens difficulty; When running into the lower fluid of temperature; The shrinkage simultaneously of flashboard and hard sealing pair causes producing the gap between flashboard and the valve seat, causes the leakage of fluid.
The soft seal pair is the outside that is coated on flashboard by rubber material, and rubber material is not corrosion-resistant, and is not wear-resistant; When the flashboard open and close, often move up and down friction, make the rubber layer wear and aging easily, come off; When high temperature fluid or manifold pressure increase; Owing to hold and can't stand increased pressure, damage easily, cause the leakage of fluid.
The model utility content
The purpose of the utility model is to overcome above-mentioned defective, and a kind of band pod apertures earthenware slab gate valve is provided, and it is through adopting ceramic seal with valve; Because of having to resist, washes away by stupalith, and corrosion-resistant and wear-resistant, the working life of improving valve; Reduce the maintenance of valve, improved manufacturing efficiency.
The purpose of the utility model realizes through following technological scheme: a kind of band pod apertures earthenware slab gate valve, and it comprises valve seat, flashboard, valve rod, pod apertures and handle, is provided with fluid inlet and fluid output in the inside of valve body; Between fluid inlet and fluid output, be provided with flashboard; The flashboard below is provided with pod apertures, connects valve rod in the upper end of flashboard, and the upper end of valve rod is provided with handle; Inside at valve body is provided with valve seat; It is characterized in that: the ceramic seal circle is installed on the said valve seat, and ceramic plate clamps flashboard, is positioned at the contacted sealing surface of flashboard and valve seat.
The advantage and the beneficial effect of the utility model are: because insert ceramic plate on the flashboard of valve, the sealing surface that flashboard contacts with valve seat is provided with the ceramic structure sealing, utilizes stupalith to have and resists and wash away; Corrosion-resistant; Wear-resistant, improved the sealing effect of valve, prolonged the working life of valve; Reduce the maintenance cost of valve, improved manufacturing efficiency.
