Summary of the invention
One aspect of the present invention provides the antifreeze control valve unit of using in a kind of outside, comprising:
An inflow entrance,
An exhaust port
A connecting passage, it is connected to exhaust port with inflow entrance,
A main valve, it is configured to open the fluid connection by connecting passage when the open operation position, and when closed operative position described connection is cut off,
An actuator, its be used to activate main valve and
One emptier, it is used for the described control valve unit of emptying when closing the working position, it is characterized in that emptier comprises a bypass pipeline, and it partly is connected to the second connecting passage part with first connecting passage.
Control valve unit according to an embodiment of the invention, making does not need to adopt two spring controlled valves in the control valve unit, so both allowed the reliable ventilation of connecting passage under congestion situations, can reflux by Security Screening again.Bypass duct can make between the connecting passage part ventilation flow, and this is to be in being emptied completely/ventilating and having created pressure condition of connecting passage in the freezing environment.
Surprisingly, demonstrated control valve unit according to an embodiment of the invention in addition be connected to this control valve unit or other can in control valve unit, produce in the presence of the flexible pipe of exhaust port of any device that other links to each other of pressure state and also shown good reliability.For example, in actual applications, first end of flexible pipe is connected to the exhaust port of this control valve unit, and second end of flexible pipe is equipped with stop valve.In this case, by closing or the stop valve at the throttling flexible pipe second end place, the pressure state in flexible pipe and the control valve unit can be kept, and need not to consider that the main valve of control valve unit is to open or close.
Under these circumstances, control valve unit has stoped the fluid of the anything unexpected that is caused by external pressure by emptier to be discharged according to an embodiment of the invention.
Another according to an embodiment of the invention improvements, thus provide safety guarantee to discharge by exerting pressure to avoid such fluid on the both sides of bypass channel, and this pressure is present in the inside of connecting passage or is connected in the flexible pipe of this passage.In such a way, the interaction energy that pressure produces in control valve unit avoids causing fluid to discharge this control valve unit, because rely on bypass channel, emptier has formed airtight circulation with regard to the environment of this control valve unit.
In this respect, in the mounting point of control valve unit, with respect to gravitational direction, preferred especially second connecting passage partly is positioned at the top of first passage part.As a result, the hydrostatic that acts on the opening that leads to first connecting passage bypass channel partly is lower than the hydrostatic that acts on the opening that leads to second connecting passage bypass channel partly.As a result, air stream flows to second connecting passage from exhaust port, passes bypass channel therefrom again, enters the first connecting passage part again via this bypass channel, thereby impels connecting passage to ventilate effectively.
Bypass channel partly is connected to ventilation space with first connecting passage and benefits, and this ventilation space provides an air drain, its can cause more uniform ventilation stream and by and the more uniform discharge fluid stream that comes.

Embodiment
As illustrated in fig. 1 and 2, control valve unit comprises exterior section 1 and interior section 2 according to the preferred embodiment of the invention.
Being arranged in the exterior section 1 is exhaust port 20, actuator 50, and the connecting passage 30 with outside connecting passage part 31-33.
Being arranged in the interior section 2 is inflow entrance 10, main valve 40, and the bottom connecting passage part 34-36 of connecting passage 30.
In this mounting point, interior section 2 is disposed in the inside of body of wall or building, and exterior section 1 is disposed in the outside of body of wall, is subjected to the influence of environment temperature outside.In this mounting point, discharge aperture 20 along gravitational direction towards the below.
In the control valve unit that Fig. 2 shows, its main valve 40 is in closed condition.Main valve 40 comprises the first valve element 41, and its concrete form is a ceramic disk, and has eccentric hole 41a, b.Main valve 40 also comprises the second valve element 42, its cross section be shaped as two triangles, their summit contacts, and is putting opposite both sides semicircular in shape therewith.The triangular surface of the second valve element 42 forms two valve sealing face 42a, b, and their size is designed to make them can seal first and second openings that are positioned at the first valve element 41.
In its closed position, main valve 40 anti-sealings arrive connecting passage 30 from inflow entrance 10, by rotating the first valve element 41 by this way with respect to the second valve element 42, promptly, make two eccentric opening 41a, b is positioned at two valve sealing face 42a of the second valve element, on the b, and sealed by the effect of sealing surface.
With the first valve element, 41 half-twists, make two eccentric opening 41a with respect to the longitudinal axis of control valve unit, b become with the second valve element 42 in two corresponding register, flow to exhaust port thereby make water to pass control valve unit from inflow entrance.
Therefore, water enters control valve unit in the horizontal direction by inflow entrance 10.After this, water can be flowed through one and is positioned at the safety check 80 in inflow entrance downstream.Safety check 80 comprises valve seat 81, and valve body 82 is pressed in the valve seat by a pressure spring 83.The pressure of water produces an active force, and offset pressure spring 83 acts on the power on the valve body face 84, and valve body 82 is risen from valve seat 81, allows water therefrom to flow through.
Then, water flows on the direction as shown by arrow B of main valve 40.
The second valve element 42 rotatably is rigidly connected to coupling unit 51, and it rotatably is rigidly connected to first end of short actuating rod 52 successively by key and slit.In its another end, the cross section of short actuating rod 52 is a Hexagon, and rotatably is rigidly connected to long actuating rod 54 by a Hexagon seat ring 53, and the cross section of described long actuating rod 54 also is a Hexagon.
At an other end of long actuating rod, long actuating rod rotatably is rigidly connected to valve pocket 56 by adaptation element 55, but both can move axially, and valve pocket 56 rotatably is rigidly connected to actuation button 57 again.Like this, a moment of torsion that is applied to actuation button 57 can be passed to the second valve element 42, so that correspondingly rotate the second valve element 42, from closing the working position that the working position moves to unlatching, vice versa with main valve 40.
Actuation button 57 and valve pocket 56 together can with respect to other component axial of control valve unit move.Have externally threaded threaded bush 58 by one, guarantee that valve pocket 56 can not skid off on the direction of actuation button from control valve unit, described outside thread is screwed on the corresponding internal thread of wall portion 122 of the housing that is positioned at control valve unit.
Being arranged between actuation button 57 and the tubular portion 32 is vent valve 70, ventilates in its inside to control valve unit.The structure of vent valve 70 and function will be described by accompanying drawing 3 and 4.
This vent valve 70 comprises valve seat 71 and valve body 72.Valve body 72 integrally forms with valve pocket 56.The valve seat 71 of vent valve 70 is formed in the adaptation element 55, and adaptation element 55 is positioned at the housing of control valve unit, and seals by two O shape circles.Adaptation element 55 comprises hole 75,76, and they provide the fluid between vent valve 70 and the connecting passage part 32 to be communicated with.
Ventilation space 100 and seals near actuation button by two O shapes circle ring 101,102 between actuation button 57 and vent valve 70.Bypass channel 110 leads near the connecting passage part 31 that is positioned at the exhaust port 20 diagonally downwards from ventilation space 100.
Like this, air can flow to connecting passage part 32 through continuous bypass channel from connecting passage part 31, and bypass channel is by bypass channel 110, and ventilation space 100 and hole 75,76 form.
Pressure spring 73 is supported on the annular shoulder of shell body wall portion, and outwards exerts pressure to valve pocket 56 and valve body 72, and described valve body comprises actuation button fixed thereon 57.
As shown in Figure 1, the locating stud 120 of radial arrangement is connected to valve pocket 56, and is directed in the pin guide rail in one of control valve unit fixing wall portion 122.Pin guide rail 121 allows axially to move inward on the direction of vent valve 70 from an initial position with the actuation button 57 of valve pocket, and wherein main valve 40 is closed, vent valve 70 work, thus by contact action, vent valve 70 is closed.When vent valve 70 was in the closed position, guide finge track 121 allowed these actuation button 57 to be rotated 90 °.This rotation is passed to actuating rod 54 through valve pocket 56, and further is passed to valve body 42 by actuating rod 54,52, and it correspondingly rotates to the enable possition.
When 90 ° of actuation button counterrotatings, spring element 73 automatically promotes actuation button and valve body 72, makes them oppositely outwards move to initial position.Therefore, allow water to flow out like this,, simultaneously, also allow remaining water from control valve unit, to flow out by exhaust port 20 because air can enter the upper area of control valve unit by bypass channel from exhaust port 20 from the inside of control valve unit.
Yet, if in control valve unit, keep certain pressure, for example, connect the pressure that flexible pipe causes, so, this internal pressure also will be applied to ventilation space 100 by bypass channel.Therefore, the ventilation of control valve unit inside can not take place, if there be remaining interior the pressure, when main valve 40 is closed, can not have liquid to infiltrate into the outside by vent valve 70 yet.So just prevented reliably that liquid is unexpectedly by vent valve 70 discharges.
Fig. 5 has shown the control valve unit according to second embodiment of the invention.Therefore this embodiment does not have vent valve, axial displacement (the particularly pushing away) enforced opening by actuation button.
The improvement of control valve unit as shown in the figure also has actuation button 157, and it rotatably is rigidly connected to long actuating rod 154 by adaptation element 155.Adaptation element 155 comprises air vent 175-177, and they are connected to bypass channel 210, and bypass channel 210 extends up to ventilation space 200 diagonally from the close position of exhaust port 120, extends to the channel part 210 of the top, hole that is positioned at bypass channel 210.So just guaranteed to have set up permanent connection by bypass channel 210, ventilation space 200 and air vent 175-177 between lower passage part 131 and the upper channel part 132, when actuation button 157 when closed position is shifted in its enable possition, guaranteed the inner ventilation reliably of control valve unit.
In embodiment as shown in Figure 5, actuation button 157 can not move axially, only can be around the longitudinal axis half-twist of outer wall valve.In embodiment as shown in Figure 5, no longer need to be used to control the connection guiding of actuation button 157.
