Abstract
The invention provides a valve special for chlorine alkali. The valve comprises a valve seat at the bottom, a valve ring connected to the upper portion of the valve seat, an adjusting ring connected to the upper portion of the valve ring, a recoil ring arranged above the adjusting ring, a valve flap arranged in the recoil ring, a guide sleeve arranged above the valve flap, a valve cover arranged above the guide sleeve, a spring arranged in the valve cover, a valve rod arranged above the spring, a backpressure base arranged on the upper portion of the valve rod, an adjusting screw arranged above the backpressure base and a valve cover arranged above the adjusting screw. Aiming at the special requirements for conveying of strong acid, strong alkali and other highly corrosive media, the valve special for the chlorine alkali is designed and formed by combining the domestic actual situation of valve application and adopting the novel sealing form and the reliable sealing structure. The valve has the characteristics that the sealing performance is stable, using is safe and reliable, the corrosion resistance is high, the internal leakage and the external leakage of the media are avoided, and operation is convenient.
Description
Technical field
The present invention relates to a kind of chlor-alkali special valve, belong to Special valve technical field.
Background technology
Valve is in fluid system, be used for controlling the direction of fluid, pressure, the device of flow be make pipe arrangement and equipment in
Medium (liquid, gas, powder) flow or stop and controlling the device of its flow.
Valve is control parts in pipeline fluid induction system, is used for changing path section and media flow direction, has
Water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, from simplest stop valve
Various valves used in extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve is from atomic little
Gauge valve reach greatly the industrial pipeline valve of 10m to latus rectum.Can be used for controlling water, steam, oil product, gas, mud, various corrosion
The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow, and the operating pressure of valve can be from
The supertension of 0.0013MPa to 1000MPa, operating temperature can be with the high temperature of the ultralow temperature to 1430 DEG C of c-270 DEG C.
In chlor-alkali production tubing, the medium of flowing generally has strong acid and strong base (Caustic soda, hydrochloric acid) hydrogen, chlorine, chlorination
Hydrogen, acetylene gas etc., they are explosive inflammable, poisonous and harmful substances, and as there is valve evaporating, emitting, dripping or leaking of liquid or gas, not only impact produces peace
Entirely, person safety, serious environment pollution again are related to.
Existing chlor-alkali special valve function is the most comprehensive.The demand in market can not be met.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of chlor-alkali special valve.
The chlor-alkali special valve of the present invention, including bottom valve seat, be connected in the valve collar above valve seat, be connected in above valve collar
Adjusting ring, it is located at the recoil circle above adjusting ring, the flap being located in recoil circle, is located at the fairlead above flap, is located at and leads
Valve gap above set, it is located at the spring within valve gap, is located at the valve rod above spring, is located at the back pressure seat on valve rod top, sets
Adjusting screw rod, be located at the valve gap adjusted above screw rod above back pressure seat.
Preferably,
Being covered with corrosion-resistant ceramic coating outside described spring, described flap uses anti-corrosive alloy material to make.
The chlor-alkali special valve of the present invention, is the particular/special requirement for the conveying of the strong corrosive medium such as strong acid, highly basic, and combines
The practical situation of domestic valve applications, uses novel seal form and reliable design of Sealing Structure to form.This type valve has
Have that sealing property is stable, safe and reliable, corrosion resistance strong, without the inside and outside leakage of medium and operate the features such as light, successfully solve
Determined chemical pipeline valve poor corrosion resistance, housing is easily bored a hole and poor sealing performance, a difficult problem for easily leakage, be particularly well-suited to
Chemical industry chlorine, the conveying of liquid chlorine pipeline, and meet the requirement used reliably and with long-term.Main property such as its sealing, safety etc.
Energy index has reached the level of world-famous product, import substitutes.
Detailed description of the invention
The chlor-alkali special valve of the present invention, including bottom valve seat, be connected in the valve collar above valve seat, be connected in above valve collar
Adjusting ring, it is located at the recoil circle above adjusting ring, the flap being located in recoil circle, is located at the fairlead above flap, is located at and leads
Valve gap above set, it is located at the spring within valve gap, is located at the valve rod above spring, is located at the back pressure seat on valve rod top, sets
Adjusting screw rod, be located at the valve gap adjusted above screw rod above back pressure seat.
Being covered with corrosion-resistant ceramic coating outside described spring, described flap uses anti-corrosive alloy material to make.
Claims (2)
