Description
Technical field
The present invention relates to process pipeline equipment technical field, especially relate to a kind of HP bypass T-way valve.
Background technique
At thermal power generation field or metallurgy, chemical industry, in the large-sized boiler systems such as Coal Chemical Industry, is save the energy, is reused by waste gas, by the steam injection high-pressure heater that made, heating is about to the cold water injecting heat boiler.When whom high price boiler side exceed specified water level to, for ensureing the normal operation of boiler, unnecessary water must be added boiler from height and discharging, play the high effect adding heater of protection.Common way is: linked by three valve strings, closes two wherein, opens one of them.Due to complicated operation, involve great expense, bring a lot of inconvenience to normal production.
Summary of the invention
The object of the invention is to design a kind of novel HP bypass T-way valve, solve the problem.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of HP bypass T-way valve, comprise valve body, lower valve base, upper valve base, valve rod, flap and Stem Mut, described valve body comprises left passage, right passage and lower channel three passages be communicated with each other, described lower valve base is fixed on described lower channel place, described upper valve base is arranged between described left passage and described right passage, and described lower valve base and described upper valve base are oppositely arranged;
Valve clack sealing surface is arranged at top and the bottom of described flap, and described lower valve base and described upper valve base are provided with the sealing surface of seat corresponding with it, and described sealing surface of seat forms sealing pair with corresponding described valve clack sealing surface;
Described valve rod upper end is connected with drive unit by described Stem Mut, and described valve rod lower end is connected with described flap; Described drive unit drives described flap to move up and down by the stroke of regulation; When described valve rod moves downward displacement, the sealing surface of seat that the valve clack sealing surface bottom described flap is corresponding with on described lower valve base forms sealing pair; When valve rod moves upward, the sealing surface of seat that described flap top valve clack sealing surface is corresponding with on described upper valve base forms sealing pair.
Described lower valve base and described upper valve base are pile-up welding hard alloy, become described sealing surface of seat through processing grinding.
Also comprise valve gap, filler and support, described Stem Mut is placed among described support, and described valve rod lower end is connected with described flap; Described valve rod top, through after described valve gap, described filler and support, is connected with described drive unit by described Stem Mut.
The present invention relates to one is arranged on high-pressure heater process pipeline, to the device that high-pressure heater is protected.
The object of this invention is to provide a kind of new Structure and energy, overcoming many valves connect the defect existed in linkage technique in the past, is that height adds water level when transfiniting, and remaining water is discharged to outside height adds by economy easily, and when economical as far as possible, keep high-pressure heater normal operation.
In the present invention, valve has an entrance, and two outlets, described lower valve base 2 and upper valve base 6 all form sealing pair by flap 3 with it.Described lower valve base 2 pile-up welding hard alloy, described flap 3, when valve rod 9 moves downward displacement, forms sealing pair with lower valve base 2 bottom it, and when valve rod moves upward, its top and upper valve base 6 form sealing pair.Described valve rod 9 lower end is connected with flap 3, and top is by valve gap 10, and filler 17, Stem Mut 23, support 20 is connected with drive unit.Under the effect of drive unit, move up and down by the stroke of regulation, open the passage of different outlet.In above-mentioned scheme, because valve body 1 has three passages, valve seat has upper valve base 6 and lower valve base 2 two valve seats, therefore when under the drive of valve rod 9 at drive unit, when moving upward, drives flap 3 to move upward simultaneously, closes left channel, open lower end passage.When valve rod 9 moves downward, drive flap 3 to move downward simultaneously, close lower side canal, open left channel.
Owing to taking such scheme, particularly take valve body 1 and there are three passages, and flap 3 can form different passages neatly under the drive of valve rod 9 from lower valve base 2 or upper valve base 6, and when a passage is opened, another passage is closed certainly.Thus make a valve possess the function of three valves simultaneously, save expense, the safe and reliable operation brought.
Beneficial effect of the present invention can be summarized as follows:
1, valve body 1 of the present invention has three passages, and flap 3 can form different passages neatly under the drive of valve rod 9 from lower valve base 2 or upper valve base 6, and when a passage is opened, another passage is closed certainly.Thus make a valve possess the function of three valves simultaneously, save expense, the safe and reliable operation brought.
2, structure of the present invention is simple, without the processing of complex parts, easy to use, cheap for manufacturing cost.
