Abstract
The invention relates to a pressure relief valve which is low in power and short in time from closing to complete opening. The pressure relief valve comprises a valve body and an elastic element, wherein the elastic element is fixed in an inlet channel of the valve body. The valve is characterized in that the valve also comprises a sealing component, a switching component and a motor; the sealing component is used for sealing the inlet channel and outlet channel of the valve body; one side of the sealing component is connected with the elastic element, and the other side of the sealing component is provided with a valve stem; the switching component is connected with the motor; a release groove corresponding to the valve stem is arranged in the circumferential direction of the switching component; when the pressure relief valve is closed, the valve stem is in compressed fit with one side of the switching component; when the pressure relief valve is opened, the motor drives the switching component to rotate, and then the valve stem falls into the release groove to move the sealing component, so as to communicate the inlet channel with the outlet channel; the motor is a DC speed reducing motor; and the switching component is fixed on the valve body preferably through a deep groove ball bearing. The valve has the advantages that the valve is simple in structure, ingenious in conception, capable of working under low voltage, low in power and short in time from closing to complete opening.
Description
Technical field
The present invention relates to a kind of pressure-relief valve, belong to the electromechanical integration field.
Background technique
The solenoid valve power of the circulation aperture φ 15 that supplies on the market is all greater than 10W now, can't satisfy battery-powered application, another kind of scheme is to adopt the mode of electric ball valve, power of motor can reduce, but valve need rotate 90 ° from closed condition to opening spool fully, time spent can't be satisfied requirement fast more than 5 seconds.
Summary of the invention
The invention provides a kind of pressure-relief valve, power is little, and valve is short from being closed to the time of opening fully.
Described pressure-relief valve comprises valve body, elastic element, elastic element is fixed in the inlet channel of valve body, it is characterized in that also comprising sealed member, switch part and motor, sealed member is used for the inlet channel of valve body and the sealing between the outlet passage, one side and elastic element join, opposite side is provided with valve rod, switch part links to each other with motor, and upwards is being provided with in its week and the corresponding release groove of valve rod, when pressure-relief valve cuts out, valve rod cooperates with a side compression of switch part, when pressure-relief valve was opened, the motor driven switch parts rotated, and valve rod falls into release groove, sealed member is moved, be communicated with inlet channel and outlet passage.
Described elastic element is preferably spring.
Described sealed member can be a diaphragm type structure, piston cylinder operator, or remaining can be communicated with the sealing configuration of inlet channel and outlet passage after moving.Described sealed member preferably adopts by the fixing diaphragm of clamp device, not only can reach predetermined sealing effect, and surface friction drag is little, and technology is simple, low price.
Described motor is a DC speed-reducing, and motor speed is 6-15r/min.
Described switch part preferably is fixed on the valve body by deep groove ball bearing.When pressure-relief valve was opened, after the motor driven switch parts rotated 10-40 °, valve rod fell into release groove.
As improvement of the present invention, described pressure-relief valve also comprises position transducer, the position information of induction valve rod.As preferred version, described position transducer is the magnetic Hall element, and valve stem tip is provided with magnet steel, and when valve rod moved to specified position, position transducer sent signal.
Adopt the present invention, after electrical power rotated very small angle, valve rod fell into release groove, moved rapidly at the effect lower seal parts of pressure reduction and spring, made suction port and air outlet lead to the purpose of release mutually.Because angle of swing is little, adopt the motor of less rotating speed, can open valve fast, because pressure-relief valve is simple in structure, the switch part rotational resistance is little, thereby can still can open valve mandril reliably under the condition of power of motor＜0.5W simultaneously.Switch part adopts deep groove ball bearing to be fixed on the valve body, and the power of can further reducing friction reduces power of motor.
The present invention is simple in structure, is skillfully constructed, and can work under low voltage, and power is little, and valve to open the time spent fully very short from being closed to.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
Fig. 2 is the left view of switch part among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, pressure-relief valve comprises valve body, motor 1, switch part 2, sealed member 3, valve rod 4, elastic element 5, position transducer 6, deep groove ball bearing 7, magnet steel 8, inlet channel 9 and outlet passage 10.Wherein motor 1 is a DC speed-reducing, and voltage is 3V, rated power 0.45w, and rotating speed is 10r/min, is fixed on the valve body of pressure-relief valve.Switch part 2 is fixed on the valve body by deep groove ball bearing 7, the one side is the disk of diameter 60mm, and along being circumferentially with and the corresponding release groove 11 of valve rod, opposite side and motor 1 are coupling, rotating center 12 biasings of switch part 2, the distance that makes release groove 11 and rotating center 12 is greater than disc radius.Because release groove 11 is big more with the ratio of valve rod 4 sectional dimensions with the distance of rotating center 12, angle of swing is just more little, therefore under the certain situation of valve rod 4 sectional dimensions and angle of swing, and rotating center 12 biasings of switch part 2, can reduce disk diameter, thus effective economical with materials.Sealed member 3 is used for the inlet channel 9 of valve body and the sealing between the outlet passage 10, sealed member 3 comprises by the fixing ring film of clamp device, the diaphragm outside embeds valve interior wall, clamp device is two disks that connect by fastening piece, one side and elastic element 5 join, and opposite side is provided with the valve rod 4 that diameter is 6mm.Elastic element 5 is a spring, and valve rod is provided with magnet steel in 4 tops, and position transducer 6 is the magnetic Hall element.
Inlet channel 9 is connected with pipeline, and normal working lower valve rod 4 is under the stopping of switch part 2, because the effect of sealed member 3, pressure-relief valve is in sealing state shown in Figure 1.When the needs release, after 15 ° of the motor 1 energising rotations, switch part 2 rotations, make valve rod 4 fall into release groove, valve rod 4 moves right sealed member 3 rapidly under the effect of air pressure and elastic element 5, and cuts off diaphragm wherein, make inlet channel 9 be communicated with the purpose that reaches rapid release with outlet passage 10, valve rod 4 moves right to limit position under the effect of elastic element 5 simultaneously, and the magnet steel 8 approximated position sensors 6 in valve rod 4 tops send the valve open signal.Valve is from being closed to the time of opening fully less than 1 second.
