Description
technical field:
the utility model relates to a kind of constant speed spring nozzle efficiently, effectively realizes the deoxygenation function to water of condensation.
background technique:
built-in deaeration plant heating power method is except the incondensable gas of middle dissolving of anhydrating, thus improve quality and the temperature of boiler feed water, effective equipment of thermal de-aeration, equipment indispensable in high parameter Large Copacity (300MW and more than) generator set boiler and nuclear power generating sets water supply system especially.
spring nozzle all has high-quality spray effect and good heat and mass transfer performance under various load, it is the critical component of built-in deaeration plant, its performance how, by the safety and stablization directly having influence on the exerting oneself of equipment, the temperature of water outlet and oxygen content and even equipment and run.
summary of the invention:
the purpose of this utility model is to provide a kind of constant speed spring nozzle efficiently.
above-mentioned object is realized by following technological scheme:
a kind of constant speed spring nozzle efficiently, its composition comprises: valve seat, valve disc, valve rod, spring, valve gap, puller bolt, described valve seat is connected with described valve disc, described valve disc is connected with described valve rod, described valve rod is connected with described spring, described valve gap respectively, and described valve gap is connected with described puller bolt.
described efficient constant speed spring nozzle, the thickness of described valve disc is 13mm, and diameter is φ 200mm, and edge, top and bottom is processed into 1 × 45 ° of chamfering, described valve disc sealing surface roughness is 3.2, and adds and ensure that sealing surface assembles vertical with described valve seat man-hour.
described efficient constant speed spring nozzle, described valve seat thickness is 72mm, and diameter is φ 242mm, uniform 4 M16 bolts hole do not run through around described valve seat, the boss diameter that top is processed with supported spring is φ 44mm, and boss center has the central through bore that diameter is φ 26.1mm.
described efficient constant speed spring nozzle, described puller bolt diameter is M30, and described puller bolt length is 120mm, and the pretightening force that described puller bolt brings and nozzle and oxygen-eliminating device body are tightly connected.

beneficial effect of the present invention:
1. the utility model is a kind of new-type oxygen-eliminating device spring nozzle, and it is widely used in single-cylinder type oxygen-eliminating device, is arranged in the water inlet space, top of oxygen-eliminating device, directly over deoxygenation unit, sprays the water of condensation of delivery (pipe) line, for the elementary deoxygenation to oxygen-eliminating device.
the utility model deaerating effect is obvious, superior reliable, the standardized designs of mass transfer, temperature conductivity, and structure simply can be mass, can reduce manufacture cost, because nozzle quantity is many, film forming is thin and even, be applicable to various load, easy access and change part, decrease site-assembled workload.
the utility model valve disc is that stainless steel round steel is made, add and ensure that sealing surface assembles vertical with valve seat man-hour, the sealability of spring nozzle is ensured with this, and ensureing that water of condensation evenly sprays, valve seat is that stainless steel round steel processes, and spring is played to the effect of lower support, the distance that spring utilizes deformation to promote to control feed pressure valve rod downwards, make nozzle with the linear unlatching of feedwater flow, when ensureing that confluent is 130t/h, nozzle pressure is lost in 0.035MPa.
the utility model valve rod is the manufacture of stainless steel round steel, ensures that valve rod can move with camber of spring, thus the displacement of control valve seat, valve gap is connected with valve seat by supporting element, makes whole nozzle be linked to be an entirety, facilitates in-site installation.
