Abstract
The utility model relates to a spiral tube type steam trap, which can be used as a common trap and a condensed water recoverer. It features that the valve body and the valve core are combined to form one spiral pipe shaped flow passage, the inlet in the lower part of the steam trap is connected via the flow passage to the inner cavity of the valve core, the outlet in the other side of the lower part of the steam trap is connected to the spiral pipe of the valve core, and the top of the inner cavity is connected to the spiral pipe. The steam trap has high working reliability, meets the requirement of maintenance-free, has wide load change range, can save power and a power device consumed by a common condensate water recovery device, and can increase the recovery rate of condensate water heat.
Description
Technical field
The utility model relates to a kind of valve, refers in particular to a kind of spiral-type steam trap.
Background technique
Most of industrial and mining enterprise all will use steam as thermal source, are a large amount of discharged steam water of condensation of heat power equipment of thermal source with steam, and these water are valuable soft water resource, contain a large amount of available heat energy again.Water of condensation discharging and recovery problem all have a significant impact production environment, quality of product and the cost of production of enterprise.Because existing STEAM TRAP all is operated under zero back pressure, water of condensation can only be discharged to sewerage, causes the waste of a large amount of soft water resources and heat.
Reclaim even do not consider water of condensation, from the technical problem greatly that also exists of STEAM TRAP, the STEAM TRAP of reliable performance seldom causes production process to run vapour in a large number on the market now, has aggravated the waste of energy and resource merely.
The main cause that causes thermal waste is that serious, a large amount of water of condensation of pipe network steam leakage do not reclaim, the steam product in the pipe network does not pass a test etc.
Summary of the invention
For the conserve water resource, improve the energy utilization rate of thermodynamic system, the utility model provides a kind of spiral-type steam trap, both can be used as common STEAM TRAP, also can be used as Condensate recovery device.
The technological scheme that its technical problem that solves the utility model adopts is:
It is characterized in that the spiral tube mode runner that is combined to form of valve body and spool, the import that wherein is positioned at the STEAM TRAP bottom links to each other with valve core cavity through runner, and the outlet that is positioned at STEAM TRAP bottom opposite side links to each other with the volute of spool, and the inner chamber top links to each other with volute.
Its flow resistance of utilizing fluid phase state to change to cause changes and reaches the purpose of hydrophobic resistance vapour, utilizes the pressure conveying water of condensation of initial steam itself.When steam condensate enters STEAM TRAP, the single-phase liquid fluid flows through volute smoothly, when in the water of condensation during entrained steam, owing to steam makes fluid vaporization in the pipe to the indirect heating of volute, produce big flow resistance, the entrained steam amount is many more, and heating Shaoxing opera is strong, flow resistance is big more, makes steam can't pass through STEAM TRAP.
Its advantage is:
(1) because volute is the runner of a special construction, without any moving element, malfunctioning phenomenon such as can not produce or gang up stuck, wherein the phase transformation of fluid just becomes gas from liquid, can not produce liquid hit phenomenon, the wearing and tearing and the cavitation of fluid and tube wall contact position are faint, so STEAM TRAP has high functional reliability, reach non-maintaining requirement.
(2) owing to the automatic hydrophobic resistance vapour of energy, the load variations scope is very wide, and this just makes same STEAM TRAP can be used for the hot equipment of usefulness of different load, makes things convenient for the type selecting and the installation of STEAM TRAP.
(3) vapor pressure fluctuation is the common phenomenon of heat distribution pipe network, when pressure raises and when making operating pressure differential become big, because the throttling action of volute makes with fixed attention water vaporize at outlet section, thereby increases resistance of water drainage, and balance is because pressure reduction increases the effect that produces; When the pressure reduction operating pressure differential being diminished, the condensate supercool degree increases, and the throttling vapography of volute reduces, thereby reduces resistance of water drainage, and balance is because the effect that pressure reduction reduces to produce.This just makes STEAM TRAP can adapt to bigger pressure surge.
(4) because strong to the adaptability of operating pressure differential, and do not rely on water level and temperature variation and work, so the variation of back pressure is little to its influence, utilize high back pressure directly water of condensation to be sent into demineralized water box, so both can save power and the power plant that apparatus for recovering consumed that coagulate commonly used, increase the recovery rate (the flash-off steam heat under the barometric pressure is recycled) of coagulating the hydro-thermal amount again.

Embodiment
In Fig. 1, valve body (1) and spool (2) be combined to form a spiral tube mode runner, the import (3) that wherein is positioned at the STEAM TRAP bottom links to each other with spool (2) inner chamber through runner, the outlet (4) that is positioned at STEAM TRAP bottom opposite side links to each other with the volute of spool (2), and spool (2) inner chamber top links to each other with volute (5).
Steam condensate enters valve body from import (3), at first enter valve core cavity, enter volute from the inner chamber top, flow into outlet (4) from top to bottom, when the single-phase liquid steam condensate enters STEAM TRAP, can flow through volute smoothly, when in the water of condensation during entrained steam, owing to steam makes fluid vaporization in the pipe to the indirect heating of volute, produce big flow resistance, the entrained steam amount is many more, heating Shaoxing opera is strong, flow resistance is big more, makes steam can't pass through STEAM TRAP, thereby reaches the effect of hydrophobic resistance vapour.
Claims (1)
1. spiral-type steam trap, the spiral tube mode runner that is combined to form that it is characterized in that valve body (1) and spool (2), the import (3) that wherein is positioned at the STEAM TRAP bottom links to each other with spool (2) inner chamber through runner, the outlet (4) that is positioned at STEAM TRAP bottom opposite side links to each other with the volute (5) of spool (2), and spool (2) inner chamber top links to each other with volute (5).
