Description
Technical field
The present invention relates to a kind of steam ball valve suitable for high-temperature metal flexible pipe.
Background technology
Mainly concentrate on the choosing of temperature-resistant material in the design and manufacture of high temperature valve particularly ball valve both at home and abroad at present
With with application it is upper, by thermal expansion, this problem is perplexed all the time, and when temperature rises to some section, temperature-compensating space disappears
Lose, due to asymmetry in conventional valves structure, cause the uneven of valve thermal expansion, valve locking failure.For this problem,
Application No. 201320165193.7, a kind of entitled Chinese patent of high-temperature ball valve are symmetrical on the valve element of the ball valve
Two valve rods are connected, valve rod is identical two, it is intended to designs the ball valve of a full symmetrical configuration so that when the temperature increases,
Valve element and valve seat can expand along respective axis, and when material selection is appropriate, each part of spherical ball valve remains normal position
Relation is put, so as to realize normal work at high operating temperatures.This scheme can improve the high temperature resistant of ball valve to a certain extent
Performance, but its heat-resisting quantity is very limited.
The content of the invention
It is an object of the invention to provide a kind of steam ball valve suitable for high-temperature metal flexible pipe, solves the resistance to height of existing ball valve
The technical problem of warm limited capacity.
In order to solve the above-mentioned technical problem the present invention, adopts the following technical scheme that：
A kind of steam ball valve suitable for high-temperature metal flexible pipe, it is characterised in that including valve body, ball is provided with valve body
Body, offered steam vent in spheroid, and the surrounding in valve body positioned at spheroid is provided with valve seat, and the left and right both ends of valve body are installed with valve
Cover, the admission opening with crossing steam vent insertion in spheroid is offered on bonnet, is provided with into water and leads to around admission opening on bonnet body
Road, intake tunnel are delivery port close to one end of spheroid, and the one end of intake tunnel away from spheroid is water inlet, bonnet and valve body it
Between be provided with valve seal pad, be connected with valve rod on spheroid.
Steam ball valve is under hot environment all the time, only allows its free line expansion to meet it by preferred material and structure
High-temperature heat expansion is inadequate, and the even high temperature corrosion that deforms in the course of time or easily destroys, and the application is easily occurring
Design intake tunnel on the bonnet of thermal expansion, can be circulated in ball valve high-temperature steam while, into the intake tunnel of bonnet
The cooling water quickly flowed or coolant are passed through, takes away caused heat in bonnet, cooling effect is played to bonnet and ball valve, is protected
Demonstrate,prove its heat resistance under high-temperature work environment.
Preferably, valve rod is symmetricly set in the both ends of spheroid, and valve rod is stretched out outside valve body, for connecting actuator.
As the presently preferred embodiments, the valve rod only has one, and welding is arranged at one end of spheroid, and valve rod is stretched out outside valve body
For connecting actuator, actuator direct action or reverse action are controlled, so as to drive the valve rod of ball valve positive or reversely rotate,
Pass through the Unscrew or closing ball valve of valve rod.
One end of valve rod is connected with spheroid, and the other end is used to be connected with actuator, is provided with filler in the cavity of valve neck, fills out
Gland is provided with material, there is hole among gland, valve rod just passes from hole, is corrected under gland and pushes down filler, on valve rod
Pairing combination butterfly spring is arranged with above gland, by setting pairing to combine butterfly spring, is occurred at valve rod micro-
Compensating action can be played during leakage, the deformation for discharging its pretension compresses filler again, improves sealing effectiveness.
Preferably, the admission opening of bonnet is suitable with the steam vent aperture excessively of spheroid.
Further, the aperture of intake tunnel is the 1/30 of admission opening aperture, both facilitates processing, and and can ensures the strong of bonnet
Degree.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is reduced in bonnet by designing intake tunnel on bonnet by being passed through coolant in intake tunnel
Temperature, the coolant of rapid flow can take away substantial amounts of heat in ball valve, and cooling protection effect is played to ball valve, and through this Shen
Ask someone repeatedly to facts have proved that the cooling-down effect of the program is obvious.
