Background technique
At present, generally use the water bailing component of drain valve as system node in steam thermal system both domestic and external, its function is the steam condensate producing after steam heat release for getting rid of.The water of condensation that the steam heat release causing because of factors such as pipe resistance and pipe insulations in for steam transmitting pipe net produces, can affect pressure of steam supply and temperature as discharged not in time.The temperature that heating network forms water of condensation is the minimum stripping temperature that supplies in whole system; The steam-heating apparatus steam condensate that heat release forms in process of production can directly affect quality of product and manufacturing efficiency as discharged not in time.The minimum serviceability temperature that in steam-heating apparatus, the formation temperature of water of condensation is heating plant.Above-mentioned two situations, steam supply ductwork pressure is more than absolute pressure 0.5Mpa, and the condensing water temperature forming is more than 150 degree (, the minimum stripping temperature that supplies in whole system) generally.Steam-heating apparatus forms the temperature minority of water of condensation below 120 degree, and (, the minimum serviceability temperature of heating plant) absolute pressure is below 0.2Mpa; Most of steam-heating apparatuss form the temperature of water of condensation between 133-165 degree, and absolute pressure is between 0.3-0.7Mpa; Also have the formation temperature of some its water of condensation of special operation condition heating plant more than 165 degree, pressure is more than 0.7Mpa.The temperature of the above formation water of condensation is the minimum serviceability temperature of heating plant.As can be seen here, the steam condensate temperature and pressure that drain valve is discharged is all within above-mentioned scope.Number of patent application: 201210248763.9 claimants disclose a kind of steam condensate normal pressure escaper, it is characterized in that: comprise upper cover, be provided with the housing of condensing water inlet, draining is dish along separate routes, displacement control valve, discharge capacity temperature adjusting dish, lower locknut and bottom and steam condensate recovery tube, described housing upper end and upper cover are spirally connected, housing lower end and bottom are spirally connected, the cylindrical of described housing lower end is bolted with lower locknut, described housing inner chamber is equipped with draining dish and the discharge capacity temperature adjusting dish being along separate routes arranged in order from top to bottom, described draining is axially arranged with point water channel communicating with housing inner chamber on dish along separate routes, described discharge capacity temperature adjusting dish is provided with the draining circular hole being communicated with point water channel, described draining circular hole is communicated with the steam condensate waste pipe being fixed on bottom, coiling circumference is radially provided with circular hole along separate routes in described draining, described circular hole is connected with displacement control valve.While continuing this product of research and development in using by dress, find that the project organization of bottom, waste pipe and the draining connecting head of above-mentioned patented product exists two unfavorable factors.1, the monomer discharge amount of normal pressure escaper is restricted: the nozzle bore of discharge capacity temperature adjusting dish and round quantity have determined the monomer discharge capacity of normal pressure escaper.On described discharge capacity temperature adjusting dish, have multiple nozzles, the osculum of the corresponding bottom of nozzle is also connected with waste pipe, waste pipe one end and bottom welding, its other end and the welding of draining connecting head, all waste pipe is fixed after running through draining connecting head, and draining connecting head is connected with reclaim line again.The bore of waste pipe is 2-3 times of nozzle upper limit bore;
