Abstract

The utility model relates to a steam trap for continuously discharging steam condensed water, which can be used for a chemical industrial device. The utility model is composed of a container (1), an upper cavity body (2), a lower cavity body (3) and a floating ball assembly (4). Through the variation of the quantity of condensed liquid, the buoyancy changes to cause the floating ball assembly (4) to move up and down, valve cores (4-4, 4-5) open or close a hole (4-9) on valve seats (4-6, 4-7), so as to control the condensed liquid to be discharged.

Description

The continuous drainage STEAM TRAP

The utility model relate to a kind of in heat enginnering the STEAM TRAP of used continuous eliminating steam condensate, special, relate to a kind of STEAM TRAP that can get rid of steam condensate continuously that can be used for chemical plant installations.

Existing STEAM TRAP has the bell bucket trap, floating-tube type STEAM TRAP, float type steam trap, bellow type STEAM TRAP, the pulsed STEAM TRAP, double-metal sheet type STEAM TRAP and thermodynamic trap etc., these STEAM TRAP mostly are the intermittent type draining, and gas barrier properties is poor during draining, cause waste steam.

Chinese patent 95239923.7 discloses a kind of equilibrium valve formula STEAM TRAP, can get rid of steam and pressurized air water of condensation automatically, connect the balance pressure valve on its lower cover, parallel coaxial is equipped with two valve blocks on relative two walls of this balance pressure valve body, the bivalve lobe, two flap activity correspondences of spool place in the two valve block holes, and spool is connected with ball float, make spool under the control of ball float, move, with the Control work media flow.Advantages such as though this patent can have continuous drainage, and gas barrier properties is better, the bimetallic strip that is adopted, complex structures such as connecting rod, and block easily, cause control sensitivity to weaken, cause the life-span shorter owing to tinsel causes metal fatigue easily under hot operation.

The object of the present invention is to provide and a kind ofly can get rid of water of condensation continuously, simple in structure again, the STEAM TRAP that the life-span is long.

A kind of continuous drainage STEAM TRAP of the present utility model, by container (1), upper cavity (2).Lower chamber (3) and ball float assembly constitute, it is characterized in that having on the top cover (1-3) of container (1) for the inlet (1-1) that contains flanged (1-2) that condensed fluid steam enters, its base plate (1-5) is fixed on the tube cover (2-2) of the upper cavity (2) that moves up and down for ball float, the top of tube cover (2-2) connects the may command ball float and upwards continues the cover cap (2-1) that moves, in container (1) extension have the bottom of the tube cover (2-2) of even distribution aperture (2-3) be connected can with lower chamber (3) flange connecting (2-4) on, cavity up and down is divided into being fixed with on the barrel of lower chamber, in, upper clapboard of following three compartments (3-2) and lower clapboard (3-3), on, following compartment is by on being fixed on, connecting tube on the lower clapboard (3-4) is communicated with, the barrel of middle compartment is provided with outlet (3-7), the lower boss (4-2) that can cover in (2-2) ball float (4-1) that floats at tube connect can be automatically along the valve rod (4-3) of axis centering, the upper valve core (4-4) and the lower valve core (4-5) that are arranged on the valve rod (4-3) can be on being separately fixed at, slide up and down on upper valve base on the lower clapboard (4-6) and the lower valve base (4-7), on upper valve base (4-6) and lower valve base (4-7), have a plurality of Φ 2-5mm holes (4-9) at the mobile position of spool;

Continuous drainage STEAM TRAP of the present utility model is simple in structure, flexibility and reliability, regulation range big can be under various operating modes stable operation.

From in April, 80 continuous drainage STEAM TRAP of the present utility model 15 covers be used for Anhui Province XX group company urea device, replace original thermodynamic trap, so far more than 19 years, stable operation, waste gas eliminating pressure is by 3.8Kg/cm ²Reduce to 3.4Kg/cm ²Eliminated the phenomenon of pressing, facts have proved that continuous drainage STEAM TRAP of the present utility model can be saved steam, made urea steam consumption per ton be reduced to 1.6 tons, thereby reduced the cost of product urea by 1.8 tons because of the too high safe valve bounce of exhaust gas pressure.

Below in conjunction with description of drawings the utility model;

Fig. 1 is the plan view of continuous drainage STEAM TRAP of the present utility model;

Referring to Fig. 1, by container (1), upper cavity (2).Lower chamber (3) and ball float assembly formations such as (4);

Container (1) comprises top cover (1-3), and cylindrical shell (1-4), base plate (1-5), top cover are provided with for the inlet (1-1) that contains flanged (1-2) that condensed fluid steam enters, and base plate (1-5) is welded on the lower outer periphery of tube cover (2-2) of upper cavity (2);

Upper cavity (2) comprises cover cap (2-1), tube cover (2-2) and with lower chamber flange connecting (2-4), the tube cover that extends container (1) in partly has even distribution aperture (2-3);

Lower chamber (3) comprises the flange flange connecting (3-8) with upper cavity, barrel (3-1), the end (3-5), on barrel (3-1), be fixed with upper clapboard (3-2) and lower clapboard (3-3), upper cavity and lower chamber are separated into compartment, middle compartment, following compartment, the barrel that to go up compartment and the middle compartment of following compartment connection connecting tube (3-4) that is fixed on upper clapboard and the lower clapboard is provided with outlet (3-7), and (3-6) is connected with the downstream by flange;

Ball float assembly (4) comprises can cover the ball float (4-1) that fluctuates in (2-2) at tube, one boss (4-2) is arranged in the bottom of ball float, boss (4-2) connects can be along the valve rod (4-3) of axis automatic centering, the upper valve core (4-4) and the lower valve core (4-5) that are arranged on the valve rod (4-3) can slide up and down on upper valve base (4-6) fixing on the upper and lower dividing plate and lower valve base (4-7), on upper valve base (4-6) and lower valve base (4-7), have 4 row 26 Φ 2-5mm holes (4-9) at the mobile position of spool;

Continuous drainage STEAM TRAP working procedure of the present invention is as follows:

Referring to Fig. 1, the ball float assembly of this figure is in lower limit position, its ball float (4-1) lower boss (4-2) seat is on upper valve base (4-6), go up (descending) spool (4-4,4-5) be positioned at (descending) valve seat (4-6, bottom 4-7), (4-9) is positioned on the spool in the hole of valve seat, up and down the condensed fluid of compartment can not pass through hole (4-9) flow in compartment discharge from outlet (3-7), increase gradually when condensed fluid enters container (1) from inlet (1-1), when liquid level rises to the ball float middle part, ball float rises, spool is along with rising, and the valve seat lateral aperture is exposed, and condensed fluid is discharged by outlet (3-7) by compartment in hole (4-9) discharge warp.The utility model relies on spool to move up and down in valve seat, and condensing liquid quantity is discharged in how many adjustings of open hole.

The limit position that tube cover control ball float rises is in order to avoid ball float rises and excessively causes that excesssive gap can not carry out the proper functioning of STEAM TRAP between boss (4-2) and the upper valve base (4-6).
