Abstract
A condensate and feed water regulating valve includes a valve body, a valve core installed inside the valve body, and a valve rod connected with the valve core. The regulating valve is characterized in that a balancing hole is formed on the valve core, and a cage flow equalizing casing is sleeved on the valve core. The condensate and feed water regulating valve of the utility model has the advantages of low possibility of cavitation, small vibration, low noise, long service life, and simple and reasonable structure. The adoption of the pressure balance structure can reduce not only the unbalanced force of the valve, but also the driving torque of the actuating mechanism, thereby realizing energy conservation. The structure designed to facilitate assembly and disassembly achieves convenience in disassembly and assembly and simplicity in maintenance.

Technical field
The utility model relates to a kind of valve mechanism, furthermore relates to the feedwater corollary equipment in power station, oil, chemical industry, the metallurgical system, the concrete modulating valve that relates in the feedwater corollary equipment.It can erosion occur in the anti-locking system and damage in the effect that occurs playing under the very big situation of pressure reduction step-down behind the pump startup.
Background technique
Feed water pump its outlet pressure when operation reaches more than the 20Mpa, and general boiler can't hold so high pressure, so need come reduction regulation with feed-regulating valve.
The feed-regulating valve with fixed attention that uses at present exists with the form of gate valve, can only realize a step-down of spool and valve seat, so the pressure drop level can only finish 50%, and the utility model has adopted this technology of shrouding, making with fixed attention, feedwater becomes repeatedly step-down through overregulating by a step-down.
The model utility content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of novel feed-regulating valve with fixed attention is provided.
In order to address the above problem the technical solution of the utility model is such:
Coagulate feed-regulating valve, comprise valve body, be arranged on the spool of valve inner, the valve rod that is connected with spool is characterized in that, has an equalizing orifice on the described spool, and valve core upper sleeve has the current-sharing cover, and described current-sharing cover is a cage current-sharing cover.
Described valve body both sides are provided with water intake and water outlet, described water intake connects the water inlet flow channel of valve inner, described water outlet connects the outlet passage of valve inner, the interlaced layout of described water inlet flow channel and outlet passage, and the axis of water inlet flow channel and outlet passage is not on same horizontal plane.
Described valve rod is made of lower valve rod and upper valve rod, and lower valve rod is connected with the spool upper end, and lower valve rod connects upper valve rod, upper valve rod connecting bushing.
Described valve body top is provided with valve gap, and the valve gap upper end connects a support, and the support upper end connects a bearing.
Be bolted to connection between described valve gap and the valve body, between valve gap and valve body, be provided with the valve gap packing ring.
Be bolted to connection between described valve gap and the support, valve gap and between between be provided with seal ring.
Be bolted to connection between described support and the bearing.
Described bearing inside is provided with the bearing of support sleeve.
Described internal stent is provided with the threaded bush who is connected with upper valve rod, has outside thread on the described upper valve rod, has internal thread on the described threaded bush, described threaded bush's connecting bushing.
The joint of described upper valve rod and lower valve rod is provided with contiguous block.
Beneficial effect, the utility model are difficult for cavitation, little, the low noise of vibration, long service life, the simple and reasonable feed-regulating valve that coagulates.Because the utility model has adopted the pressure balance type structure, has reduced the valve unbalanced force, has also reduced the driving moment of actuator, has saved the energy, simultaneously owing to being designed to install and remove easy structure, so the utility model easy accessibility, easy to maintenance.The utility model can be realized multistage step-down, greatly reduces the probability of the erosion of throttling element, and has designed equalizing orifice, has reduced unbalanced force, has reached the effect of anti-cavitation in the design, prolongs 2 times working life than the general feed-regulating valve that coagulates.
