Abstract
The utility model provides a high -temperature ball valve, includes the valve body, be equipped with in the valve body with the spheroid of valve rod fixed coordination, and be provided with the disk seat between valve body and the spheroid, the valve body include part A and part B, part A and disk seat between be provided with the sealing washer, part A and part B between be provided with and hold the chamber, hold the intracavity and be provided with the thermoelectric generation piece, the upper portion of thermoelectric generation piece still be provided with the LED lamp, thermoelectric generation piece electricity generation supply with the LED lamp, the LED lamp controlling opening and closing of siren. The utility model discloses following beneficial effect has: in case the long -time back of using, the sealing washer takes place ageingly or high temperature corrosion, results in the sealing washer to damage and loses efficacy, can in time send out the police dispatch newspaper, prevents that high temperature liquid from further damaging valve body and disk seat and valve rod, in time ends and decreasing.
Description
Technical field
This utility model relates to valve field, is specifically related to a kind of high-temperature ball valve.
Background technology
In order to control the flow of fluid in the high temperature conduit such as chemical pipeline, pipeline arranges high-temperature ball valve.But
The structure of common high-temperature ball valve is the spool being contained in valve body, and spool is connected with valve rod, and the outer end of valve rod passes valve body and handle
It is connected.When needing regulated fluid flow, pull handle and drive valve core rotation by valve rod, say, that control spool
Rotational angle, thus change the unlatching scope of spool.Although, it can reach regulate flow purpose, but spool with
It is typically with what sealing ring sealed between valve body, in the effect lower seal of high temperature fluid medium during spool unlatching certain limit
May premature breakdown, thus affect the normal use of ball valve.
After sealing ring in ball valve damages, owing to letting out in being, generally it is difficult to discover, until discovering, high temperature
Liquid is in being permeated with valve seat, thus affects whole device, the miscellaneous part after high temperature corrosion such as valve body, valve seat, valve
Bar is likely to be destroyed, and being badly in need of now a kind of technology can quickly know when sealing ring lost efficacy, and can play alarm
And reminding effect, quick-replaceable, it is to avoid loss.
Utility model content
For deficiency of the prior art, this utility model provides a kind of high-temperature ball valve, after solving sealing ring damage,
Can not find in time to change, cause miscellaneous part valve body, valve seat, valve rod by the problem of high temperature corrosion.
For reaching object above, the technical solution adopted in the utility model is:
A kind of high-temperature ball valve, including valve body, is provided with in described valve body and the spheroid of valve rod secure fit, and valve body and ball
Being provided with valve seat between body, described valve body includes components A and part B, is provided with between described components A and valve seat
Sealing ring, is provided with cavity volume between described components A and part B, be provided with thermo-electric generation sheet, described temperature in cavity volume
The top of difference generating sheet is additionally provided with LED, described thermo-electric generation sheet generating supply LED, described LED
Control the opening and closing of siren.The sealing ring between components A and valve seat is utilized to play daily sealing function, but
Being when sealing ring lost efficacy or damaged, high-temp liquid enters part B region, if, with instantaneous thermo-electric generation to LED
Lamp is powered, and LED launches glittering light beam, and photosensitive switch is opened, and starts siren, and siren can send powerful
Sound, until the user discover that, manual-lock siren, change sealing ring.
As preferably, the photoswitch that the downward-sloping alignment of described LED is arranged on siren.Due to light
Rectilinearity, utilizes the Aligning degree being obliquely installed higher, is affected little by the dust in air and antibacterial.
As preferably, the connecting position of wires epoxy sealing of described LED and thermo-electric generation sheet.Wire connects
On the one hand place's epoxy sealing has effectively fixed whole device, on the other hand ensure that sealing, the ash in air
Dirt and moisture content enter not go.
Compared with prior art, after this utility model has the advantages that once long-time use, sealing ring is sent out
Raw aging or high temperature corrosion, causes sealing ring to damage and lost efficacy, it is possible to send alarm in time, prevent high-temp liquid from damaging further
Bad valve body and valve seat and valve rod, stop loss in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing in C region in Fig. 1 of the present utility model.
Detailed description of the invention
Hereinafter describe and be used for disclosing this utility model so that those skilled in the art are capable of this utility model.Hereinafter retouch
Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modification.
A kind of high-temperature ball valve, including valve body 2, is provided with in described valve body 2 and the spheroid 5 of valve rod 1 secure fit, and valve
Being provided with valve seat 4 between body 2 and spheroid 5, described valve body 2 includes components A 21 and part B 22, described parts
It is provided with sealing ring between A21 and valve seat 4, between described components A 21 and part B 22, is provided with cavity volume, in cavity volume
Being provided with thermo-electric generation sheet 3, the top of described thermo-electric generation sheet 3 is additionally provided with LED 31, described thermo-electric generation
Sheet 3 generating supply LED 31, described LED 31 controls the opening and closing of siren 6, described LED
The downward-sloping alignment of lamp 31 is arranged at the photoswitch on siren 6, described LED 31 and thermo-electric generation sheet 3
Connecting position of wires epoxy sealing.
The situation that sealing ring damages once occurs, and high-temp liquid is originally blocked by sealing ring, sealing ring and components A 21
Gap is opened, and high-temp liquid enters the bottom of parts B22 from gap, and the bottom of thermo-electric generation sheet 3 flows through the most hundreds of
The high-temp liquid of degree, thermo-electric generation sheet 3 upper end is identical with outside normal room temperature, and therefore both produce huge temperature approach,
Utilize the principle generating supply LED 31 of thermo-electric generation, luminous after LED 31 energising, the LED being obliquely installed
31 are irradiated to the photoswitch on siren 6, and photoswitch is high to the sensitivity of light, when receiving illumination, and siren
It is unlocked, the buzzer generation sound in siren, remind user to leak, timely phase down valve, change and seal
Circle.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Planting changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requirement
Protection domain defined by appending claims and equivalent thereof.
