Abstract
The utility model relates to a gas timing-controller, comprising a crust, a timer and a liquid control system. The liquid control system is provided with a valve body providing with a gas nozzle and an outlet, a hollow nut, a valve core, a link stopper, a spring, a soft sealing head, a bowl-shaped sealing ring, a lever, a rolling wheel and a cam. The utility model is mainly used for the timing control of the liquid of the civil combustion gas and other small caliber pipe lines.
Description
The utility model belongs to a kind of pipeline mechanical timer control gear, is a kind of device that utilizes mechanical timer to blind off a line.Mainly be applicable to the timing controlled of civilian combustion gas and other small-bore pipe road fluid.
The timing device that existing mechanical is blinded off a line is made up of the mechanical transmission structure that shell, timer and a cover may command pipeline close, open.Said mechanical transmission structure promptly has installation tool transmission part formation on the axle of valve at installation tool transmission part on the transmission shaft of timer and another.Existing apparatus is owing to adopt the mechanical transmission structure control valve, and structure is comparatively complicated, also is easy to occur error, causes leaking, and simultaneously, needs the component of highi degree of accuracy such as fan-shaped cam, ratchet, tooth sector, sour jujube bar, ratchet again, both processing difficulties, and cost is high again.
The purpose of this utility model is the mechanical timer control gear of blinding off a line of a kind of simple in structure, safe and reliable, solar term of design.For domestic gas provides a kind of comparatively ideal control apparatus.
The utility model gas timing control device is by shell, a timer and a cover liquid control system are formed, liquid control system has valve body, hollow nut, the valve stamen, spring, soft sealing head, bowl ring, lever, roller and cam, cam is fastened on the axle of timer, so that with its rotation, there are two steps at valve stamen middle part, on valve stamen one end link stopper is arranged, bowl ring is on the step at valve body middle part, spring housing is at valve stamen middle part, one end is topped bar with the valve stamen and is contacted, the other end is blocked by hollow nut, make the valve stamen produce thrust, the outlet port of soft sealing head in valve body, the valve stamen has an end of link stopper outside the valve body chamber, the other end is in the valve body chamber, block the hole of soft sealing head, hollow nut is connected with the threaded one end of valve body, push down bowl ring, block spring, one roller is arranged on the lever, ship and resell on another market lever is connected on the bearing support of valve body one end, the lever middle part leans against on the link stopper of valve stamen one end, the roller of lever leans against on the cam, the valve stamen can be sphere valve stamen or conical valve petal, valve stamen one end is cylindrical, the other end is taper, block the hole on the soft sealing head, in valve pocket, be between sealing head and the bowl ring, because sealing is fine, under the effect of fluid circuit pressure, can make the cylindrical portion of valve stamen stressed greater than tapered portion, make its soft sealing head pressurized again, the hardness of valve stamen is higher than soft sealing head, link stopper on the valve stamen is fixed with nut, soft sealing head can be by plastics, rubber or soft metal are made, bowl ring, in valve pocket, be subjected to fluid circuit pressure, paste the valve stamen tightlyer, sealing is just better, and then, prevented to enter the gas of valve pocket, excessive pollution of liquid and damage device, cause poisoning, accidents such as blast, the spring of retaining in valve pocket keeps certain tension force, to promote valve stamen shutoff outlet, makes this device be in normally off, only move lever handle or the turn timer just can draw back the valve stamen, open outlet, move on on the cylindrical on the basic circle of roller on the lever simultaneously, because cam and timer are synchronous by cam, lean against the roller on the cam, one to the time of determining, cam is got back to basic circle from cylindrical, closes outlet.
The utility model gas timing control device owing to be conceived to the improvement of liquid control system, does not need complicated driving mechanism, device is simplified, avoided the error that may occur in the mechanical transmission course, made regularly and dam more reliably, processing and fabricating also is easy to simultaneously.
