Abstract
A passive timing mechanical valve comprises a knob, a nut, a gas inlet cavity, a gas outlet cavity, a pressure roller, a pressure lever, an ejector rod, a sealing gasket, a spring, a mechanical timerand a valve port, and is characterized in that the upper end of the nut is connected with a gas inlet pipeline, and the lower end thereof is connected with the gas inlet cavity; the gas inlet cavity is connected with the gas outlet cavity through the valve port; the knob is connected with an input shaft at one end of the mechanical timer; the pressure roller is sleeved on the input shaft of the mechanical timer and is coaxially and synchronously connected with the mechanical timer; one end of the pressure lever is connected with the pressure roller in a sliding manner, and the other end thereof is connected with one end of the ejector rod in a moving manner; the other end of the ejector rod penetrates the valve port and is movably connected with the sealing gasket; and the spring is in reverse contact with the sealing gasket. The valve has the beneficial effects of self closing, good leak tightness, low cost and dispensed power supply, thereby achieving a wide application prospect. Except for the piping gas industry, the valve can also be applied in the control of tap water valves, landscape sprinkling irrigation valves, kitchen and washroom water-saving valves and cooking timing valves.
Description
Technical field
The utility model relates to a kind of machinery valve, relates in particular to a kind of passive timing machinery valve.
Background technique
Traditional mechanical type valve generally only is only limited to open and close valve manually, realize timing controlled, generally takes additive electronic control part, valve driving part to realize.More complicated not only, the cost height, and need the power supply power supply.
The model utility content
The purpose of this utility model is exactly in order to remedy the deficiencies in the prior art, the passive timing machinery valve that provide a kind of and can close automatically, reliable in structure, good airproof performance, cost are low, need not power supply.
To achieve these goals, the technological scheme of the passive timing machinery valve that the utility model is related is such: a kind of passive timing machinery valve, comprise knob, nut, air-inlet cavity, outlet chamber, pinch roller, depression bar, push rod, sealing gasket, spring, mechanical timer, valve port, the nut upper end is connected with admission line, the lower end is connected with air-inlet cavity, described air-inlet cavity is connected with outlet chamber by valve port, knob is connected with the input shaft of mechanical timer one end, pinch roller be set on the input shaft of mechanical timer and with coaxial synchronous connection of mechanical timer, one end of described pinch roller and depression bar is slidingly connected, the other end of depression bar is done to move with an end of push rod and is connected, the other end of push rod passes valve port and sealing gasket flexibly connects, and spring is from oppositely contacting with sealing gasket.
The passive timing machinery valve that the utility model is related, described valve also comprises the fixed plate that is fixed on the outer cover, described mechanical timer passes fixed plate and fixedlys connected with fixed plate.
The passive timing machinery valve that the utility model is related, described valve also comprises outer cover and bottom, described outer cover and described bottom are connected and fixed by screw.
The passive timing machinery valve that the utility model is related, the outlet chamber afterbody has a ripple head, and this ripple head can connect with the flexible pipe that is connected of controlled kitchen range.
The passive timing machinery valve that the utility model is related has following beneficial effect:
1. non-transformer requirement is highly suitable for the occasion of fire prevention, anti-riot requirement;
2. timing automatic is closed, and 0～90 minute adjustable, carries out quantitative or time-controlled application for needs, can realize by the mode of the scheduled time, and is very convenient.
3. cost is low, and volume is little.
4. because valve is to close to have under the double action of spring potential energy and medium differential pressure to close that valve is reliable, the characteristics of good airproof performance.
The present invention has a extensive future, and expansion a little promptly can be applicable to water-saving valve control between running water valve control, the control of gardens sprinkling irrigation valve, Kitchen hygiene, the control of cooking Timed valve.

Fig. 2 is passive timing machinery valve A-A generalized section;
Fig. 3 is passive timing machinery valve B-B generalized section.
Embodiment
Passive timing machinery valve of the present utility model is specifically described as follows in conjunction with Fig. 1 to Fig. 3: this valve comprises knob 1, outer cover 2, nut 3, air-inlet cavity 4, bottom 5, outlet chamber 6, fixed plate 7, pinch roller 8, depression bar 9, push rod 10, sealing gasket 11, spring 12, mechanical timer 13, valve port 14.Described outer cover 2 and described bottom 5 are connected and fixed by screw.Nut 3 upper ends are connected with admission line, and the lower end is connected with air-inlet cavity 4, and described air-inlet cavity 4 is connected with outlet chamber 6 by valve port 14, and outlet chamber 6 afterbodys have a ripple head, and this ripple head can connect with the flexible pipe that is connected of controlled kitchen range.Knob 1 is connected with the input shaft of mechanical timer 13 1 ends, and described mechanical timer 13 passes fixed plate 7 and fixedlys connected with fixed plate 7, and described fixed plate 7 is fixed on the outer cover 2.Pinch roller 8 be set on the input shaft of mechanical timer 13 and with 13 coaxial synchronous connections of mechanical timer, described pinch roller 8 is slidingly connected with an end of depression bar 9, the other end of depression bar 9 is done to move with an end of push rod 10 and is connected, the other end of push rod 10 passes valve port 14 and flexibly connects with sealing gasket 11, and spring 12 is from oppositely contacting with sealing gasket 11.
The working principle of this passive timing machinery valve is as follows: pinch roller 8 is coaxial synchronous with mechanical timer 13, mechanical timer 13 is realized valve control is closed in the timing of valve by pinch roller 8, earlier prefabricated two operating angles on pinch roller 8: the one, and pinch roller 8 makes depression bar 9 make the start angle (less about about 10 °) of swing; The 2nd, pinch roller 8 mechanical timer 13 is turned clockwise angle that the deadline presets (about 180 °, but preset time 0-90 minute).Driving pinch roller 8 when knob 1 turns clockwise makes depression bar 9 swing in start angle rapidly, promote push rod 10 opening encapsulation pads 11, make fluid media flow to outlet chamber 6 by air-inlet cavity 4, continuing 1 deadline of rotary knob presets, pinch roller 8 rotates counterclockwise in preset time, and sealing gasket 11 is held open state.When preset time arrives, pinch roller 8 is got back to start angle, and push rod 10 discharges, and sealing gasket 11 is finished valve closing under the double action of the elastic potential energy of spring 12 and medium differential pressure.
