Abstract
The invention is a floating ball type drain valve belonging to valve technology field; it solves the problem that the current valve continuous water and gas discharge ability deficiency. The drain valve includes a valve and a shell, there has an inlet and outlet on the valve, the shell is connected to the valve, there has a floating ball in the shell, the floating ball is hinged with valve, the shell also has a gas discharging aperture and a water discharging aperture, the gas and water discharging apertures are all connected to the water outlet of the valve, the floating ball is connected to a sealed ball, when the floating ball is inclined, the sealed ball is at the position blocking the water discharging aperture. A connector is arranged in the valve, and there has a back resisting device in the connector. The floating ball type drain valve can discharge water and gas continuously with large quantity. Even the pressure in the channel is decreased to zero, it can work normally; at the same time, it can avoid the phenomenon that the water seal will affect the gas discharge.
Description
Technical field
The invention belongs to valve technology field, particularly a kind of drain valve.
Background technique
Drain valve generally is installed in the pipeline of steam and gas utilization unit system, and the water of condensation in the automatic blowdown piping of energy is to improve the conveying vapour efficient of pipeline.In existing drain valve,, directly influenced the normal use of drain valve because the unreasonable structure of outlet valve exists problems such as steam leakage is serious, the unlatching sensitivity of valve is not high.
At present, Ball float steam trap is a kind of more satisfactory drain valve, and it has characteristics simple in structure, stable and reliable for performance.But the continuous drainage of Ball float steam trap or venting capacity have certain deficiency.Show that manifold pressure hour can't draining or exhaust, perhaps Pai Fang speed is very slow.Simultaneously, also exist the temperature volume lower, whole valve body in water of condensation when discharging big, install and use defective such as inconvenience.
Summary of the invention
The objective of the invention is provides a kind of structure improved Ball float steam trap at the existing the problems referred to above of existing drain valve, makes it have drainage exhaust ability preferably, and characteristics such as volume is little, easy to install.
Purpose of the present invention can realize by following technical proposal: this Ball float steam trap comprises valve body and housing, water intake and water outlet are arranged on valve body, housing and valve body are connected, and are provided with ball float in housing, and ball float and valve body are hinged, it is characterized in that, also be provided with outlet valve and drain opening in the described housing, outlet valve and drain opening all communicate with the water outlet of valve body, and a ball sealer is being connected on ball float, when ball float tilted, ball sealer was in the position of blocking drain opening.
In above-mentioned Ball float steam trap, be provided with a fittings body in the described valve body, fittings body and valve body are connected, and an endoporus that connects fittings body is arranged in the fittings body, above-mentioned outlet valve and drain opening all communicate with an end of fittings body endoporus, and the other end of fittings body endoporus communicates with water outlet.
In above-mentioned Ball float steam trap, be provided with a check device in the described fittings body.This check device is made up of be criss-cross catch, back-up ring and the dividing plate that are loaded on successively in the fittings body.
In above-mentioned Ball float steam trap, described outlet valve comprises top board, valve block, positioning seat and spool, and wherein top board and positioning seat snap together, valve block places between the two, spool and positioning seat are connected, and vent is arranged in the spool, and several inlet holes are arranged on the positioning seat.
In use, when more water was arranged in this Ball float steam trap, ball float contacted with water, and ball float floats under buoyancy function, and ball sealer is along with ball float rises, and separated with drain opening, and drain opening is on state.Like this, the current that entered by water intake can be after drain opening, passes through from the water outlet of valve body.If the current that enter in the drain valve are less, ball float just is in the position of inclination.Like this, ball sealer is on the position of blocking drain opening, and drain opening is closed.At this moment, the steam in the pipeline will outwards discharge by outlet valve and fittings body.
It is that material is made that the integral body of this Ball float steam trap can adopt stainless steel, have withstand voltage, anti-cavitation performance, and volume is little, easy to install.
Compared with prior art, the advantage of this Ball float steam trap is:
1, because the structure that the ball float that has adopted and ball sealer are connected, drain valve can continuous drainage and a large amount of exhausts, though in pipeline pressure drop to zero, also can proper functioning.
2, because water intake and drain opening are in the lower position of valve body, the phenomenon that just can avoid influencing the air discharging because of water seal takes place.
3, outlet valve is set in valve body,, also air and carbon dioxide can be drained even pressure is very low.

Embodiment
As shown in Figure 1, this Ball float steam trap comprises parts such as valve body 1, housing 2, ball float 3, outlet valve 5 and drain opening 6, and housing 2 is connected with valve body 1.Joint at valve body 1 and housing 2 is provided with pad 8, is tightly connected to guarantee valve body 1 and housing 2.
As shown in Figure 1, in the present embodiment, be provided with fittings body 7 in valve body 1, fittings body 7 is connected with valve body 1.In the endoporus 71 of fittings body 7 check device is housed, this check device is formed by being criss-cross catch 72, back-up ring 73 and dividing plate 74.Catch 72, back-up ring 73 and dividing plate 74 set gradually.Current or steam are entered by outlet valve 5 in the endoporus 71 of fittings body 7 by housing inner chamber 21, by catch 72, back-up ring 73 and dividing plate 74, discharge from water outlet 12 at last.But when current or air etc. were oppositely entered by water outlet 12, catch 72 will be sealed the endoporus 71 of fittings body 7, and they can not be back in the inner chamber 21 of housing 2 by fittings body 71.
