Abstract
The utility model super-large displacement steam trap, the drain valve are characterized in the drain trap using welding procedure manufacture.Valve body is divided into three sections, big orifice coaxial double valve sheet lever and floating hydrophobic switch is installed at the export direction partition board of stage casing, condensed water is adjusted using lever and floating to discharge, the super-large displacement steam trap maximum displacement is up to 980 ton hours, the valve empties pneumatic module equipped with bimetallic, inlet is welded with large area filter screen, there is blowdown plug before filter screen, the online blowdown of energy and purging pipeline, flange is imported and exported on the same level central axes of valve body, it is easy for installation, the use demand of various super-huge heat transmission equipments can be met.
Description
Technical field
The utility model super-large displacement steam trap, in particular for the draining system of especially big steam heat-exchanging equipment.
Background technology
According to market survey, with China's rapid economic development, the introduction of many large scale equipments and large-scale coal chemical industry, oxidation
The large construction projects such as aluminium, big ethylene, polysilicon are extended, and the huge discharge drain valve generally used currently on the market has been difficult to meet
The market demand, the reason is that general hydrophobic valve chest is all to use model casting, valve inner space is limited, the draining of drain valve maximum
Amount is usually no more than 100 ton hours, some low voltage differences, and the draining system of huge discharge can only use 7-8 huge discharge drain valve simultaneously
Networking.
Invention content
In order to solve super-large displacement steam trap problem, the utility model super-large displacement steam trap uses weldering
Connect technique, manufactured and designed the super-large displacement steam trap of pot type according to the market demand, maximum hydrophobic amount can reach 980 tons/
Hour, which is divided into three sections, and the lever and floating that stage casing export direction partition board is equipped with coaxial double valve sheet big orifice is dredged
Taps, the first half empty pneumatic module equipped with bimetallic.It is welded with large area filter screen panel and blowdown in condensed water Way in
Plug, can online blowdown and purging pipeline.The inlet and outlet flange of drain valve is on the same level central axes of valve body, piping installation
Easily.
Description of the drawings
Attached drawing 1 is:The partial cutaway view of super-large displacement steam trap.
In attached drawing:Drain valve tank body (1) blind flange (2) bimetallic gas deflation assembly (3) bolt/nut (4) valve bonnet seal pad
(5) lever (6) lever and floating (7) filter screen (8) condenses water inlet (9) blowdown plug (10) valve rod connecting pin (11) valve seat (12)
Valve core link rod (13) nut (14) valve block (15) nut (16) gasket (17) connecting pin (18) condenses water out (19)
Specific implementation mode
Embodiment further illustrates the utility model below in conjunction with the accompanying drawings.
As shown in the picture, super-large displacement steam trap is mainly by drain valve tank body (1) blind flange (2) bimetallic exhaust group
It is stifled that part (3) bolt/nut (4) valve bonnet seal pad (5) lever (6) lever and floating (7) filter screen (8) condenses water inlet (9) blowdown
Head (10) valve rod connecting pin (11) valve seat (12) valve core link rod (13) nut (14) valve block (15) nut (16) gasket (17) is even
Outbound (18) condenses water out (19) and forms.
The super-large displacement steam trap is characterized in the valve body (1) using the manufacture of pressure vessel welding procedure, drain valve
Inlet and outlet flange on the same level central axes of valve body, valve inner space is divided into three sections, stage casing export direction isolation board
The hydrophobic switch of lever and floating of coaxial double valve sheet big orifice is installed, the first half is being condensed equipped with bimetallic emptying pneumatic module (3)
Water inlet direction is welded with large area filter screen (8) partition board and blowdown plug (10), can online blowdown and purging pipeline.Work as drain valve
When bringing into operation, air and low-temperature condensate in pipeline enter through drain valve condensation water inlet (9), and bimetallic empties pneumatic module
(3) it opens, air is discharged by bimetallic emptying pneumatic module (3), and condensed water constantly enters, and liquid level rises, lever and floating (7)
Rising with liquid level and lever (6) is driven to connect coaxial valve block (15) rising, opens drain valve, condensed water is discharged through valve seat orifice (12),
When steam is into fashionable, bimetallic emptying pneumatic module (3) encounters temperature distortion after steam, and spool is closed, when condensed water stops entering
When, lever and floating (7) declines with liquid level, and coaxial double valve sheet (15) is driven to close drain valve.The drain valve is multiple functional, draining
It measures especially big, the hydrophobic demand of especially big heat transmission equipment in current Chinese market can be met.
Claims (4)
