Abstract
The invention relates to a ball valve capable of preventing liquid from expanding during spraying. The ball valve comprises a supporting piece valve body, a ball core, an adjusting device and sealing elements, wherein the ball core is arranged inside the valve body and provided with a through hole; the adjusting device is connected with the ball core and extends to the outside of the valve body; the sealing elements are arranged between the valve body and the ball core as well as between the valve body and the adjusting device; and one end of the valve body is connected with a liquid inlet pipeline, and the other end of the valve body is connected with a liquid outlet pipeline. The ball valve is characterized in that: the ball core is provided with at least one pressure relief hole which passes through the outer side of the ball core and the through hole of the ball core, is positioned on the ball core and faces one end of the liquid inlet pipeline when the ball core is in the closed state under the adjusting action of the adjusting device. In the ball valve capable of preventing the liquid from expanding during spraying, pressure can be released automatically when the pressure rises due to temperature rise or vibration and the like of the liquid in the valve cavity of the ball valve, and liquid conveying safety is enhanced; moreover, the ball valve is easy to process and has long service life.
Description
Technical field
The present invention relates to a kind of ball valve, particularly relate to a kind of ball valve that prevents that the liquid spray from rising.
Background technique
In fields such as chemical industry, oil, smelting, often need the line transportation hydrogen peroxide, hydrogen peroxide is a kind of strong oxidizer liquid with strong corrosion, for avoid it to leak will using usually sealability preferably ball valve carry out pipeline control.Ball valve is installed on the hydrogen peroxide pipeline, its basic principle is: the valve inner of ball valve has the ball core of a band through hole, the top-slitting of ball core, link to each other with controlling device, the torsion that imposes on the controlling device can reach the ball core, the ball core is rotated, when rotating to the axis parallel of ball core through hole and valve body around the valve body center line, valve is promptly opened, and hydrogen peroxide passes through; When ball core again behind the half-twist, the through hole on the ball core is blocked, valve is promptly closed, and has cut off flowing of hydrogen peroxide in the pipe.Place the Sealing that reaches between ball valve body and the ball core between valve body and the controlling device to make ball valve realize good sealing effect.
This shows that the hydrogen peroxide by ball core through hole during the ball valve opening state can be deposited in along with the rotating part of closing the ball core of ball valve in the cavity of ball core through hole and valve body formation.
Hydrogen peroxide is a kind of explosive substance, when being heated to more than 100 ℃, can begin rapid decomposition, in addition it with understand the formation explosive mixture after organic substance mixes, be impacted, be heated or the electrical spark effect under can blast.The fluid that has this specific character of hydrogen peroxide in the industry is a lot, when the pipeline of temperature rising or conveyance fluid is subjected to clashing into, the hydrodynamic pressure that stops in the cavity that ball core through hole in the ball valve and valve body constitute also can raise, this moment is if pressure release in time, the chamber inner fluid will swell from the sealing part spray of ball valve, infringement ball valve valve member destroys ball valve sealing, brings hidden danger to safety in production.
Summary of the invention
Purpose of the present invention promptly provides and a kind ofly raises or vibrated etc. former thereby the ball valve that can self-relieving blowout prevention when boosting rises when stopping fluid Yin Wendu in the ball valve valve pocket, improve the Security that liquid is carried, and processing is simple, long service life.
For solving the problems of the technologies described above, the present invention takes following technological scheme: a kind of ball valve that prevents that the liquid spray from rising, comprise the supporting element valve body, place the ball core with through hole of valve inner, link to each other with the ball core and extend out to the controlling device of valve body outside, place the Sealing that reaches between valve body and the ball core between valve body and the controlling device, described valve body one end links to each other with input duct, the other end links to each other with the fluid pipeline, it is characterized in that, described ball core is provided with at least one relief hole that connects ball core outside and ball core through hole, described relief hole be positioned at described ball core be taken in the regulating action of described controlling device when making ball valve be in closed condition towards an end of described input duct.
Preferably, the aperture of described relief hole is 2-5mm.
Preferably, described Sealing adopts teflon to make.
The ball valve that prevents that the liquid spray from rising of the present invention can leak into the input duct that is connected with ball valve with the liquid that boosts that stops in the ball valve valve pocket by the relief hole on the ball core, realize releasing pressure automatically, and processing is simple, and the Sealing that the polytetrafluoroethylmaterial material of use is made can prolong the working life of ball valve.
Description of drawings
Fig. 1 prevents the structural representation of the ball valve preferred embodiment opening state that the liquid spray is risen for the present invention is a kind of.
Fig. 2 is the structural representation of ball core 1 among Fig. 1.
1-ball core among the figure, 2-relief hole, 3-controlling device, 4-valve body, 5-input duct, 6-fluid pipeline, 7-Sealing.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, a kind of ball valve that prevents that the liquid spray from rising, comprise supporting element valve body 4, place the ball core 1 with through hole of valve body 4 inside, link to each other with ball core 1 and extend out to the controlling device 3 of valve body 4 outsides, place the Sealing 7 that reaches between valve body and the ball core between valve body and the controlling device, valve body 4 one ends link to each other with input duct 5, the other end links to each other with fluid pipeline 6, ball core 1 is provided with a relief hole 2 that connects ball core 1 outside and ball core 1 through hole, when the regulating action that relief hole 2 is positioned at ball core 1 fooled controlling device 3 makes ball valve be in closed condition towards an end of input duct 5.
Fig. 1 is for when ball valve is opened, and fluid is by the through hole on the ball core 1; When ball valve is closed, controlling device 3 drives ball core 1 after valve body 4 center lines are done rotation, and the through hole on the ball core 1 is blocked, and the outside of ball core 1 directly contacts with the interior liquid of pipeline, feed liquor in ball core 1 outside one end and the input duct 5 contact, and the other end and fluid pipeline 6 interior fluids contact; Stop segment fluid flow in the valve pocket that the through hole of ball core 1 and valve body 4 form, when temperature raises or the pipeline that links to each other with ball valve when reason such as being vibrated and causing the stop liquid pressure rise, the liquid that boosts leaks into input duct 5 by the relief hole 2 that connects ball core 1 outside and ball core 1 through hole on the ball core 1, has realized self-relieving function.When the aperture of relief hole 2 was 2-5mm, the pressure release effect was better.
Place the Sealing 7 that reaches between valve body 4 and the ball core 1 between valve body 4 and the controlling device 3 to adopt teflon to make, have acid resistant alkali, high temperature resistant, corrosion resistant characteristics, can prolong the working life of ball valve.
