Abstract
The utility model relates to a timing stop valve, comprising a timer and a controlling valve, which is characterized in that a main shaft of the timer is sheathed with a short lever. A projected block on the short lever can push a valve rod, a bottom spherical head of the valve rod can push an angle-shaped rod to turn in order to open and close a valve disk, and the loaded strength of the timer can be lightened owing to the functions of the special oblique line of the project block and the reinforcement of the angle-shaped rod. The utility model has the advantages of high safety, simple structure, easy fabrication and low cost, which can be widely used for fluid controlling systems, such as various household burner stoves, timing gas supplying, water supplying, material supplying, etc.
Description
The utility model relates to regularly cut-off valve of a kind of fluid.
In recent years, in real life and patent documentation, the timing valve of some mechanical structures occurred, wherein timer is used clock-type mechanical timer, the various one-way valves of valve, stop valve membrane valve, cone valve etc.The interlock mode of timer and valve is then had nothing in common with each other, the complex structure that has, and it is more to increase driven accessary, and the timer that has is subjected to load bigger, and the stand under load time is longer, and the wearing and tearing that certainly will influence its element are accelerated or damage, reduce the life-span, even comparatively fast scrap.This type of clock timer is mainly used in electric fan, washing machine etc. above the circuit control, belongs to the mechanism of underload.Therefore technological improvement must take into full account the stand under load intensity that how to alleviate timer, and is longer to reach working life, durable in use, accomplishes simple in structurely simultaneously as far as possible, and with low cost being convenient to promoted.
The purpose of this utility model provides a kind of clock timer and is subjected to load lighter, and is simple in structure, and fluid with low cost and long-lived is cut-off valve regularly.
The purpose of this utility model is achieved in that with reference to accompanying drawing 1 and is illustrated.Fig. 1 is regularly the structural drawing of cut-off valve, and it is made up of timer and control valve two-part.
Admittedly overlap a quarter butt (2) on the knob main shaft (1) of clock-timer, quarter butt will be with main shaft (1) rotation, and the other end of quarter butt has projection (3), and projection (3) is made of two sections skew lines and one section garden arc, referring to shown in Figure 2.When main shaft (1) forwards certain position clockwise to, after determining the control time, main shaft (1) and quarter butt (2) reverse inhour, when timer arrives stop position, projection (3) moves down first knob (4) and valve rod (5), the position of center line of valve rod (5) and main shaft (1) center of rotation vertical line position level are C apart, second knob (6) by valve rod (5) the other end, tighten up torsion spring (7), promoting dihedral bar (8) rotates around hinge (9), the valve disc (10) that has Sealing and be cemented on the dihedral bar (8) is swung to the right, and close port (11) is cut off fluid and is flowed.As shown in Figure 1, otherwise timer leaves stop position, and projection (3) contacts with first knob (4) disengagement, under spring (7) effect, dihedral bar (8) upwards rotation valve rod (5) moves up, so valve disc (10) is swung left, valve port (11) is opened the communication fluid and flowed.
The utility model makes timer in most of timing controlled process, do not bear the load that valve brings, even regularly finishing, the short time before and after the close port, its suffered load is also less, because the special oblique line of projection (3), make pressure angle less, the boosting function of dihedral bar (8) is arranged again simultaneously, can make quarter butt (2) and timer stand under load slight, thereby timer is used for a long time, safe and reliable.This is simple in structure, easily manufactured, with low cost simultaneously.
It is as follows to narrate relevant details referring now to Fig. 1:
In order to change sliding friction into rolling friction, can locate to install additional roller (12) in upper and lower two and half knobs (4) and (6) of valve rod (5), as shown in Figure 3.The α angle of projection (3) and β angle can be chosen in 15 °~65 °.The position of center line of valve rod (5) and main shaft (1) center of rotation vertical line position level can be chosen in 2~18 millimeters at a distance of C, the A angle (see figure 1) of dihedral bar (8) is chosen in 70 °~90 °, its length and hinge position are determined by conventional method according to circumstances, make every effort to compact, and can play suitable boosting function, when mounted, valve port is closed and timer clock and watch gear stall synchronous coordination.This structure except that Sealing with rubber or the Expanded graphite, all available ferrous metal of remaining parts, non-ferrous metal or engineering plastics are made.
The utility model is widely used; the fluid control of centering, low pressure small flow is more suitable; as various domestic gas cooking stoves; Timing water supply, air feed, feed etc. all can be used; both can bring convenience in life to everybody; can play safety protection and saving effect again, adopt electric wind fans timer can realize timing and often open two grades.Select for use respectively,, also can play pressure-reducing function if it is less to adjust the valve port gap.
Claims (5)
1, a kind of timing cut-off valve is made up of timer and control valve, it is characterized in that on the knob main shaft (1) of timer, overlapping quarter butt (2) admittedly, the other end of quarter butt (2) has projection (3), projection (3) is made of two sections skew lines and one section garden arc, there are second knob (4) of going up and (6) in the valve rod of control valve (5) two ends, the position of center line of valve rod (5) and main shaft (1) center of rotation vertical line position level are C apart, dihedral bar (8) one ends and second knob (6) plane contact, the other end is the dihedral minor face, be consolidated with the valve disc (10) of band Sealing on it, this structure except that Sealing with rubber or the Expanded graphite, remaining parts can be used ferrous metal, non-ferrous metal or engineering plastics are made.
2,, it is characterized in that the α angle of projection (3) and β angle choose in 15 °~65 ° by the described timing cut-off valve of claim 1.
