Description
The present invention relates to a kind of according to different purposes, the boiler three-dimensional changing valve of the flow direction of hot water in the convertible boiler relates to the boiler three-dimensional changing valve that a kind of method of utilizing motor rotary valve 360 to spend is changed the productivity that can improve valve and the sealability of direction of flow specifically.
Common employing direction changing valve changes the flow direction of fluid when utilizing the line transportation fluid, and takes difform direction changing valve according to the number of gateway, and the valve that wherein has two selection functions is called the three-dimensional changing valve.
This kind direction changing valve generally includes manually and electronic two types, and wherein manually operated valve is by the flow direction of manual operations conversion liquid, and mortor operated valve is then changed the flow direction of liquid automatically by motoring.
For different demand supply heating installation waters or warm water according to the user, boiler generally adopts the three-dimensional changing valve, especially in order to realize remote operation, in the function of indoor control setting boiler elsewhere, adopts motorized motions formula three-dimensional changing valve more.
Boiler commonly used is driving according to motor with electrodynamic type direction changing valve, spends by rotary valve 180 degree or 360 and opens or seal stream.The domestic 93-4229 number special permission bulletin of Korea S, 96-6604 model utility bulletin and 2000-959 number special permission bulletin are situated between and have recruited related content, shown in Fig. 1 a～Fig. 1 c.
The problem that exists in the three-dimensional changing valve at present commonly used be since be provided with respectively fixed motor fixed plate, be provided with the intermediate plate and the fixing lower plate of ball assemblying body of the contact portion of induction rotational speed, so combination three-way valve needed time is long, the cost of production height.
In addition, the center line of the axle of motor commonly used and bent axle is not on same straight line.For the rotating force with motor is sent to bent axle, need establish corresponding control gear in addition, factors such as technician's package technique and service time will influence the reliability and the durability of control system in this case.
In addition, the switch that is arranged on the intermediate plate processes with copper coin, be difficult to guarantee the reliability of point of contact, therefore also need to establish in addition control gear, thereby improved the difficulty of assembling, productivity is reduced, be directly exposed in the external environment owing to point of contact simultaneously, working life is shorter, also breaks down easily.
It is less to the purpose of this invention is to provide a kind of unnecessary parts, and has the three-way cross valve for boiler of high leak tightness.The present invention is based on the reliability design skill and technique and be worth engineering, redundancy design arranged side by side and quality coefficient have been improved, motor, switch and bent axle are fixed on the fixed plate through accurate design, and make the axle of motor and the center line of bent axle on same straight line, thereby unnecessary parts have been reduced, improved productivity, and be arranged on the dual O shape circle on the bent axle, made three-way valve have higher sealability.
The object of the present invention is achieved like this.A kind of three-way cross valve, by valve body, fixed plate, valve shaft, ball valve, motor and engine casing (Eng Cas) constitute, wherein three of valve body gateways are located on the same horizontal line, fixed plate is located at the valve body upside to guarantee sealing, valve shaft connects fixed plate central authorities, ball valve is fixed on the fixed plate downside of valve shaft, motor is combined in the fixed plate upside of valve shaft by cam, it is characterized in that the cam first half and Lower Half are provided with the opposite projection of both direction, the upper and lower of cam central authorities is provided with the one or four chamfered groove and the two or four chamfered groove, rise with four cornicults that are located at the valve shaft upside with motor reel respectively and combine, so that the center line that makes motor reel and valve shaft is on same straight line, engine casing (Eng Cas) is located at and is used to cover motor on the fixed plate.Valve shaft is combined closely with fixed plate with two O shapes circle, guaranteeing sealing, and is fixed on the fixed plate with jump ring, also accompanies a plain washer therebetween.An annular projection that is slightly larger than the through slot of ball center is established in the valve shaft lower end, spheroid is clipped between the eccentric disk of annular projection and valve shaft, the cam periphery is provided with sensitive switch in addition, whether contacts opening and closing of may command sensitive switch between this sensitive switch and cam projection.
Three-way cross valve of the present invention, by valve body, fixed plate, valve shaft, ball valve, motor and engine casing (Eng Cas) constitute, wherein three of valve body gateways are located on the same horizontal line, fixed plate is located at the valve body upside to guarantee sealing, valve shaft connects fixed plate central authorities, ball valve is fixed on the fixed plate downside of valve shaft, motor is combined in the fixed plate upside of valve shaft by cam, it is characterized in that the cam first half and Lower Half are provided with the opposite projection of both direction, the upper and lower of cam central authorities is provided with semi-circular groove and croze, combine with motor reel and valve shaft top respectively, so that the center line that makes motor reel and valve shaft is on same straight line, valve shaft is combined closely with fixed plate with two O shape circles, to guarantee sealing, upside fixed bolt level insertion at fixed plate is fixed on valve shaft on the fixed plate, also accompanies a plain washer therebetween.Combine the back with eccentric disk for fear of spheroid and break away from valve shaft, the lower end of valve shaft central authorities is provided with jump ring.The cam periphery is provided with sensitive switch in addition, whether contacts opening and closing of may command sensitive switch between this sensitive switch and cam projection.
Advantage of the present invention is that the fixed plate that platform is set and is located at the ball of valve shaft of fixing version, sensitive switch has been realized integrated, thereby improved productivity, simultaneously owing to adopted sensitive switch, the open and-shut mode of valve when correctly induction motor rotates, the connection part of valve shaft and fixed plate is provided with dual O shape circle in addition, has further improved the sealability of system.
