Description

A kind of STEAM TRAP

Technical field

A kind of STEAM TRAP relates to a kind of improvement of structure of steam-water separator of the block steam and drain water that uses for vapour system.

Background technique

In industrial processes, in industries such as petrochemical industry, chemical industry, weaving, light industry, electric power, use in large quantities steam especially.The water and air that condenses in the steam is the harmful matter that affects exchange heat and pipeline passing capacity, in order in time to get rid of the water of condensation in the vapour system, the leakage of minimizing steam, improve the thermal efficiency that steam uses equipment, usually in steam-heating apparatus or the online feeder apparatus STEAM TRAP of steam pipeline, the performance of STEAM TRAP directly affects the quality of steam operational system.

The problems such as at present, the discharge of mechanical trap condensed water mostly adopts the throttling of valve type manual, can not automatically regulate, and being parked in a position can not change with the water yield, does not have energy-saving effect, and the ubiquity life cycle is short, maintenance cost is high.

Summary of the invention

The utility model is exactly the problem for above-mentioned existence, propose a kind of simple in structure, be active in one's movements, large flow STEAM TRAP that life cycle is long.

The purpose of this utility model is the logical following technological scheme realization of keeping.

A kind of STEAM TRAP, its structure comprises: tank shape STEAM TRAP housing, be positioned at the steam inlet pipe of housing sidepiece, be fixed in the normal open modulating valve of tank shape STEAM TRAP lower housing portion, vertically be positioned at the floating drum of tank shape STEAM TRAP housing, the outlet pipe that the upper end is fixed between two parties is that tank shape STEAM TRAP housing top shell covers, the lower end is positioned at floating drum; It is characterized in that its structure also comprises:

One protection sleeve, this protection sleeve be the gap be sleeved on described floating drum outer, by support be fixed on the tank shape STEAM TRAP inner walls, open the uniform straight tube that has through hole on the barrel.

A kind of STEAM TRAP of the present utility model is characterized in that its structure also comprises a water outlet control valve, and this water outlet control valve is the straight tube that sidewall has osculum, on its external wall of upper portion and outlet pipe inwall slip, the bottom is fixed at the bottom of the floating drum inner core.

A kind of STEAM TRAP of the present utility model is characterized in that its structure also comprises a floating drum position-limited lever, and this position-limited lever is for being fixed between two parties tank shape STEAM TRAP housing bottom vertical bar.

A kind of STEAM TRAP of the present utility model is characterized in that described upper end is fixed on outlet pipe that tank shape STEAM TRAP housing top shell covers, that the lower end is positioned at floating drum between two parties, divides the 2-section pipe that divides for by flange connect in tank shape STEAM TRAP enclosure interior; And has the wear-resisting lining layer in the lower joint outlet pipe.

A kind of STEAM TRAP of the present utility model, simple in structure, be active in one's movements, the water yield can auto-control processed changes, and realizes automatically regulating, and reaches the purpose of effective reduction energy consumption, can effectively prolong life cycle, reduction maintenance expense.

Embodiment

A kind of STEAM TRAP, its structure comprises: tank shape STEAM TRAP housing 1, be positioned at the steam inlet pipe 2 of housing sidepiece, be fixed in the normal open modulating valve 3 of tank shape STEAM TRAP lower housing portion, vertically be positioned at the floating drum 4 of tank shape STEAM TRAP housing, the outlet pipe 5 that the upper end is fixed between two parties is that tank shape STEAM TRAP housing top shell covers, the lower end is positioned at floating drum; Its structure also comprises: a protection sleeve 6, this protection sleeve be the gap be sleeved on described floating drum outer, by support 7 be fixed on the tank shape STEAM TRAP inner walls, open the uniform straight tube that has through hole on the barrel; A water outlet control valve 8, this water outlet control valve is the straight tube that sidewall has osculum, on its external wall of upper portion and outlet pipe inwall slip, the bottom is fixed at the bottom of the floating drum inner core; A floating drum position-limited lever 8, this position-limited lever is for being fixed between two parties tank shape STEAM TRAP housing bottom vertical bar 9; The outlet pipe that described upper end is fixed between two parties is that tank shape STEAM TRAP housing top shell covers, the lower end is positioned at floating drum divides the 2-section pipe that divides for by flange connect in tank shape STEAM TRAP enclosure interior.

During operation; when water of condensation, the vapour mixture steam inlet pipe STEAM TRAP from tank shape STEAM TRAP housing sidepiece; gas-vapor mix is subjected to enter in the floating drum after stopping of protection sleeve that floating drum is provided with outward; isolated gas then filling the upper space mineralization pressure in the STEAM TRAP housing; water or vapour are entered from the water outlet control valve of the bottom of center outlet pipe, discharge along outlet pipe.

The liquid that water enters in the floating drum at most is just many, and how much floating drum deadweight and the water that enters are heavy has determined that floating drum falls and the distance of come-up, and throttle orifice is opened greatly with sinking, and come-up is closed few, thereby plays the effect of self-regulated.

The normal open modulating valve that is fixed in tank shape STEAM TRAP lower housing portion is used for guaranteeing that the water about 90% can discharge condensed water 90% under the situation of motionless at floating drum (heavy or floating), the draining insufficient section makes the interior water level rising of floating drum, weight increase and sink, sink restriction is opened greatly, increase discharge capacity.

Since produce condensing capacity 90% by being fixed in the normal open modulating valve discharge of tank shape STEAM TRAP lower housing portion, the workload of water outlet control valve and the volume of STEAM TRAP can have been reduced, simultaneously balance the pressure difference before and after the water outlet control valve, can not fall after having avoided the too large floating drum of pressure reduction to rise.

The outlet pipe that described upper end is fixed between two parties is that tank shape STEAM TRAP housing top shell covers, the lower end is positioned at floating drum divides the 2-section pipe that divides for by flange connect in tank shape STEAM TRAP enclosure interior; Its lower end is provided with lining and clamps in order to having worn and torn with flange and is convenient for changing.

When water enters the interior certain altitude of container, floating drum is risen, be limited after drive normal open mouth rises to certain altitude, this moment is by outlet pipe discharge water about 90%.If row is untimely for water, water is at floating drum 5 internal water accumulations, and water level rises, and floating drum (moisture) is when increasing the weight of to exceed buoyancy of water, and cylindrical shell falls, and adjustment hole descends thereupon, and water outlet is increased, and draining increases, and reaches the purpose of automatic adjusting.Because wear-resistant metal material is adopted at position easy to wear, use 3-5 without necessity of maintenance and repair; Large flow water effluxes from the bottom, and solid particulate matter can not be deposited in the container yet even if having in a small amount.
