Embodiment
As shown in Figure 1, mechanical pressure adjustable automatic switch valve is made up of spherical valve device, pressure transmission device, equilibrium of forces transmission device and regulator etc.Spherical valve device was from ball valve was different in the past, the start stop lever that it is rotated around spherical valve core hinge by a rhizosphere controls, the centre of sphere place of spherical valve core is positioned at around the hinge point rotated, but start stop lever must turn to several angle could drive spherical valve core to rotate, and the rotation of spherical valve core directly control the on off state of valve.Pressure transmission device is made up of thicker cavity, pressure transmission spearhead and pressure transmission bar, and the pressure of valve output pipeline drives pressure transmission bar to slide by the piston movement of pressure transmission spearhead.Thrust balancing device is made up of start stop lever, pressure transmission bar and balance spring etc., and start stop lever controls the rotation of spherical valve core.Counterpressure means is made up of back pressure spring and adjusting color screw etc., the pilot pressure of adjusting color screw by regulating the tightness of pressure spring to realize regulating valve, the upper end Bonding pressure transmission pole of back pressure spring, it is poor that the elastic potential energy of regulator and the pressure of pressure transmission bar form a pair backpressure, the motion of control force Equilibrator.Meanwhile, at the spherical valve core of spherical valve device and be placed with sealing film between the pressure transmission spearhead of housing and pressure transmission device and housing and seal, prevent liquid or gas from leaking outside.
Spherical valve device is made up of input adapter 1, valve housing 2, sealing film I 3, spherical valve core 4, out splice going splice 5 etc.Input adapter 1 is connected with input pipeline, and out splice going splice 2 is connected with output pipeline; Sealing film I 3, between valve housing 2 and spherical valve core 4, seals, and prevents liquid or Leakage Gas; Have internal channel in the middle of spherical valve core 4, when spherical valve core 4 inlet opening and delivery outlet are relative with position, output tube road junction with supplying tube road junction respectively, valve is in opening state, otherwise valve is in closed condition; The right side of spherical valve core 4 has the opening of several angle, the valve housing 2 of spherical valve device has the opening slot of several angle, spherical valve core 4 is connected with start stop lever 12 by the hinge 13 at its center, when start stop lever 12 is pressed in the opening of spherical valve core 4, spherical valve core 4 can be driven to rotate, the angle of valve housing 2 opening slot is greater than the angle of spherical valve core 4 opening, and can meet control valve and open and the object of closing.
Pressure transmission device is made up of a thicker cavity (upper right quarter of valve housing 2), sealing film II 6, pressure transmission spearhead 7, pressure transmission bar 8 etc.Pressure transmission device top communicates with output terminal water pipe, and sealing film II 6 is positioned at
cavity walland between pressure transmission spearhead 7, seal, prevent liquid or Leakage Gas; Pressure transmission spearhead 7 does piston movement in the upper right quarter cavity of valve housing 2, and pressure transmission bar 8 is fixed on below pressure transmission spearhead 7, together moves with pressure transmission spearhead 7, pressure transmission bar 8 has a fixing pin 9 be connected with equilibrium of forces transmission device; There is stopper 14 lower end of pressure transmission bar 8, is connected with regulator.
Equilibrium of forces transmission device is made up of fixing pin 9, balance spring 11, start stop lever 12 etc.Have sliding eye 10 at start stop lever 12 right-hand member, balance spring 11 is placed between the left end of sliding eye 10 and fixing pin 9.When pressure transmission bar 8 moves, fixing pin 9 on it slides in the sliding eye 10 of start stop lever 12, and drive balance spring, simultaneously and regulator control switch controlling rod 12 rotate, start stop lever 12 and pressure transmission bar 8 annexation partial enlarged drawing are as shown in Figure 2.
Regulator is made up of stopper 14, back pressure spring 15, adjusting color screw 16 etc., and stopper 14, back pressure spring 15, adjusting color screw 16, pressure transmission spearhead 7, pressure transmission bar 8 are on same straight line.Back pressure spring 15 is arranged between stopper 14 and adjusting color screw 16, and adjusting color screw 16 is screwed on valve housing bottom righthand side support by screw thread, and adjusting color screw 16 is used for setting the pressure of regulating valve switch by the screw thread rotation number of turns.
Working principle: at this, illustrates working principle of the present invention for water on solar water heater.When the water yield in solar water heater is less, when in pressure transmission device, the inside water pressure of cavity is very little, the Driving force of the water that pressure transmission spearhead 7 is subject to is also very little, it will be positioned at the upper end of cavity under the effect of back pressure spring 15, start stop lever 12 is by the drive of fixing pin 9, rotate the top of upper pendulum to valve housing 2 opening slot around hinge 4, valve is in open mode; When the water yield in solar water heater increases gradually, in pressure transmission device, the inside water pressure of cavity also becomes large gradually, water to pressure transmission spearhead 7 Driving force also become large gradually, back pressure spring 15 is compressed gradually, fixing pin 9 is from the rightmost cunning left of sliding eye 10, start stop lever 12 bottom gradually, leave ball-type spool 4 opening top, balance spring 11 is compressed gradually, when balance spring 11 is compressed to minimum value, fixing pin 9 slides into the most left side of sliding eye 10, and start stop lever 12 is up to the standard position, and it is following that it starts to encounter spherical valve core 4 opening; When the water yield in solar water heater continues to increase, balance spring 11 oppositely extends the Driving force brought with pressure transmission bar 8 and jointly compresses back pressure spring 15, when back pressure spring 15 compresses, start stop lever 12 also bottom promotion ball-type spool 4 turns clockwise; When making water in solar water heater, when back pressure spring 15 is compressed to minimum, now also the bottom is to the bottom of the opening slot of valve housing 2 for start stop lever 12, and start stop lever 12 promotes spherical valve core 4 by valve closing, stopping of fetching water.Otherwise when in solar water heater during discharge reduction, in pressure transmission device, the inside water pressure of cavity also diminishes gradually, when little to a certain extent time valve be in open mode, continue auto-watering.
using method: at this, illustrate when fetching water use for solar water heater.During use, this valve is directly installed in the inlet pipeline of solar water heater, just as installation common valve, input adapter 1 connects running water pipe, out splice going splice 5 connects solar energy intake pipe, when solar energy installation conditions (as height etc.) is different, user, when fetching water for the first time, regulates the valve pressure regulated value being applicable to this user by adjusting color screw 16, after this can realize unattended automatic control, realize the automation of fetching water.
This valve not only can be used for solar water heater, also can be used for other water supply, liquid or gas valve recloser occasion.
