Description
Technical field
The present invention relates to nuclear reactor equipment technical field, more particularly to a kind of blowoff valve for nuclear power station.
Background technology
Evaporator is the fluid in the important component in nuclear reactor nuclear island, reactor coolant, i.e. primary Ioops flow, its
The heat for carrying nuclear reactor nuclear reaction generation is entered in evaporator, is transferred heat under conditions of being physically isolated two times
Lu Shui, after secondary circuit water is heated, generation steam is with driving steam turbine etc., and secondary circuit water is condensed into aqueous water by three Loop Waters again
After add in secondary circuit.Although secondary circuit water is recycled in the course of the work, secondary circuit water in cyclic process still
So loss is serious, so, it is necessary to constantly supplement water into secondary circuit in evaporator practical work process.
Because the loss problem of secondary circuit water, the Water-quality control of secondary circuit water is extremely difficult in the prior art, often to two
Loop Water carries out blowdown, is to maintain the important means of secondary circuit water water quality.This allows for the blowoff valve pair of control of sewage disposal pipe break-make
The normally operation of nuclear reactor is extremely important.However, being faced with serious sealing face damage in the process of running with scum valve
Problem, further improves the structure design of blowoff valve, is those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
It is faced with serious sealing face damage problem in the process of running for blowoff valve in the prior art, further improves
The problem of structure design of blowoff valve is those skilled in the art's technical problem urgently to be resolved hurrily, uses the invention provides one kind
In the blowoff valve of nuclear power station, the blowoff valve enables to sealing surface to obtain good protection in the course of the work.
Problem is solved by following technical essential provided by the present invention for the blowoff valve of nuclear power station：For nuclear power station
Ingate and outlet opening are provided with blowoff valve, including valve seat and the valve element that is arranged on valve seat, the valve seat, ingate is with going out
It is provided between oral pore on intercommunicating pore, the intercommunicating pore and is provided with seal section, the seal section is located at the end of intercommunicating pore, and close
The hole section of envelope section front end is seamlessly transitted with seal section.
In this structure, the intercommunicating pore is the connecting hole of ingate and outlet opening, valve element and seal section phase on intercommunicating pore
After interaction, it can be achieved to the blocking between ingate and outlet opening, conversely, ingate is turned on outlet opening, blowoff valve work.
In this structure, by limiting the mode that connects of the hole section of the position and seal section of seal section with going up seal section front end on intercommunicating pore,
After may be such that impurity is entered in intercommunicating pore, impurity can maximum possible under action of a fluid so that impurity reach seal
When at fragment position, the direction of motion of impurity can be consistent as far as possible with the flow direction of fluid, and impurity is mitigated and corresponding to reach
Seal the purpose of the intensity of section surface and spool face interaction, the final effect for realizing protection sealing surface.
Further technical scheme is：
The seal section is that the part for coordinating with seal section is on the bellmouth being arranged on intercommunicating pore, the valve element
Conical section, arrival end of the one end that the bellmouth is relatively large in diameter towards intercommunicating pore.This sealing surface form is easy to process, meanwhile,
Blowoff valve is blocked under state, and the relative position of valve element and valve seat is easy to keep, and keeps blocking performance beneficial to blowoff valve is kept.
As a kind of implementation for being easy to processing, the ingate is parallel to each other with outlet opening, the axis of intercommunicating pore and
The axis of ingate is vertical, and ingate is located at the top of outlet opening.In this programme, during blowdown valve opening becomes big,
Reside in the impurity at sealing surface smoothly can be discharged under the washing away of fluid.
For ease of realizing the connection of blowoff valve and both sides pipeline section, while ensureing the sealed reliability of joint face, in addition to set
The two panels adpting flange being placed on valve seat, the arrival end of ingate and the port of export of outlet opening are connected to a piece of connection method
Sealing surface on orchid, and adpting flange is tongue and groove.
The invention has the advantages that：
In this structure, the intercommunicating pore is the connecting hole of ingate and outlet opening, valve element and seal section phase on intercommunicating pore
After interaction, it can be achieved to the blocking between ingate and outlet opening, conversely, ingate is turned on outlet opening, blowoff valve work.
In this structure, by limiting the mode that connects of the hole section of the position and seal section of seal section with going up seal section front end on intercommunicating pore,
After may be such that impurity is entered in intercommunicating pore, impurity can maximum possible under action of a fluid so that impurity reach seal
When at fragment position, the direction of motion of impurity can be consistent as far as possible with the flow direction of fluid, and impurity is mitigated and corresponding to reach
Seal the purpose of the intensity of section surface and spool face interaction, the final effect for realizing protection sealing surface.
Brief description of the drawings
Fig. 1 is the structure sectional view of blowoff valve one specific embodiment of the present invention for nuclear power station.In figure
Numbering is followed successively by：1st, valve seat, 2, ingate, 3, outlet opening, 4, valve element, 5, seal section, 6, intercommunicating pore, 7, conical section.
Embodiment
With reference to embodiment, the present invention is described in further detail, but the present invention structure be not limited only to it is following
Embodiment.
Embodiment 1：
As shown in figure 1, the blowoff valve for nuclear power station, including valve seat 1 and the valve element 4 that is arranged on valve seat 1, the valve seat
