Abstract
The present invention provides a discharge valve used for chemical plant, which is characterized in that: a valve clack, valve seat and a valve base are arranged in a hole of valve, wherein, the valve base is fixed in the valve body by interference or bonding type, other accessories are clearance fit, the contact planes among the accessories form airproof surface of valve, the T-shaped hole on the bottom of valve base connected with T-shaped shaft, T-shaped groove through valve base and shaft sleeve connected with valve clack on the bottom of valve sleeve, and bond is used are connected with T-shaped shaft, a disk-shaped spring is arranged on the top and bottom surface of shaft sleeve and nut by T-shaped shaft, the screw thread on the top of the nut and the T-shaped shaft can adjust seal pressure of valve seat and valve base. Running handle in clockwise and counterclockwise can drive valve base and valve clack rotating 90 degrees, make the channel holes with the same shape on the valve base turn-on or cut-off, so the valve can be open and close conveniently. The present invention has merits of rapid switch, small operation torque, material saving, convenient usage and maintain, and long service life.
Description
Technical field
The invention of this reality belongs to the valve in universal machine field, especially is widely used in the discharging valve on the reactor device in the chemical process.
Background technique
Existing discharging valve is mainly stop valve (as accompanying drawing 1), the sealing of this valve is to rely on the spiral of the threaded stem mode that moves up and down, make the sealing plane of flap and the sealing surface on the valve body, finish its opening-closing process by contact pressure, its shortcoming is that screw thread moves up and down that not only switching speed is slower, and need certain spatial position, material bonds herein easily, its reason is because the chemical material in the reactor all is the higher materials of a little viscosity, what have is exactly synthetic adhesive, when being easy to glue, the interior media of the official post valve of the temperature of temperature in the still and valve export combines in the valve body, if (do not have suitable temperature, removing is a very difficult thing), make valve closing not tight, moment of torsion increases, and opens and closes difficulty, causes and damages and accident potential.
The model utility content
Task of the present invention provides a kind of discharging valve, it not only can make valve opening and closing fast, medium releases easily but also economical with materials, makes that the production run of equipment is more safe and reliable.
To achieve the above object, solution of the present invention is: establish on the top of valve body inner bore that flap, middle part are established valve seat, valve base is established in the bottom, wherein, valve seat adopts interference or bonding mode to be fixed in the valve body, other part is a Spielpassung, and the plane that above-mentioned part is contacted each other all constitutes the sealing surface of valve.The T oblique crank Z connect the valve base bottom T shape hole, pass T-slot that valve seat, axle sleeve, axle sleeve bottom connect flap, and be connected with the T oblique crank Z with key, belleville spring by the T oblique crank Z, place on the upper and lower end face of axle sleeve, nut, lock behind the seal pressure with the screw thread adjustable valve seat on nut and T oblique crank Z top, valve base.Clockwise and rotate counterclockwise that handle can drive valve base simultaneously together, flap is done 90 ° of rotations, make the runner hole that has same shape on flap, valve seat, the valve base connect or block.
After adopting such scheme, because the member of valve body is an integral body, structural strength is good, processing and easy to manufacture, and valve is formed in a slice flange, but economical with materials reduces production costs.
The operation moment of torsion is little, start-stop performance good: utilize the deadweight of valve base and the power self seal valve door of the set of the pressure in container spring, therefore, frictional force is less during switch.
The material of releasing is quick: valve passage is straight-through structure up and down, and medium does not have jam, and handle rotates 90 degree just can realize switch, and operation is rapid.
The structure length of valve is short, and flap can not adhere to the phenomenon of luming by occurrence temperature decline medium during valve closing near container bottom when flange was connected with container.
