Abstract
The utility model discloses self-pressure switch valve, it has the control mouth that has the ring flange to open on the outer wall of the valve body upside that the inlet other end is the liquid outlet in one end, be connected with the valve port on the ring wall of inlet is followed to the inboard of this control mouth, the bowl form valve has been fallen on the ring flange, the bottom seat of bowl form valve is on the valve port, there is the flashboard and opens there is little feed liquor pipe the bottom upside of bowl form valve, the upside of flashboard is equipped with the check board, the upside of bowl form valve is provided with the apron, it has little liquid outlet and is linked together with the liquid outlet through the pipeline that is provided with little control valve to open. The valve has the advantages of simple structure, easy operation, long service life, good sealing performance, and functions of an on-off valve and a check valve.
Description
The utility model relates to a kind of valve, especially a kind of self-pressure controlled valve.
At present, making in the society and use in valve many kinds are arranged, but the technological scheme that mostly adopts spiral lifting or landing flashboard realizes, though the valve of this structure can be realized its task, but have following defective: the one, the making required precision strictness of its screw pair component and flashboard, sluice gate, so its manufacture cost height; The 2nd, in use easily cause wearing and tearing or corrosion to damage between each component, be subjected to certain limitation its working life; The 3rd, bigbore valve operation effort is maybe needed to be equipped with the power plant that control is closed or closed.
Task of the present utility model is to provide a kind of simple in structure, low cost of manufacture, easy operating, long service life, good seal performance, need not to be equipped with power plant, the function that promptly has switch valve has the function of check valve again, especially adapts to the self-pressure controlled valve in large flow pipe road.
Task of the present utility model takes following technological scheme to realize.Be to have with valve body on the outer wall of valve body upside of liquid outlet to be a control mouth angle and that have flange plate at one end for the liquid entering hole the other end, in the inboard of this control mouthful along being connected with the valve port that has angle with valve body on the ring wall of liquid entering hole, on the flange plate on the control mouth, be located in the bowl-shape valve that useful elastic material is made, the base part seat of bowl-shape valve drops on and makes its liquid entering hole and liquid outlet partition on the valve port is two spaces, upside is positioned with flashboard in the bottom of bowl-shape valve, on the bottom of bowl-shape valve and flashboard, be provided with the little liquid inlet pipe that liquid entering hole and bowl-shape valve insertion are connected, little liquid inlet pipe is sleeved in the pilot hole on the support that is positioned on the valve interior wall, being positioned with at the upside of flashboard can be with the elasticity check plate of little liquid inlet pipe blanking cover, be provided with cover plate and by holding down bolt this cover plate and bowl-shape valve be positioned on the flange plate in the control mouthful at the upside of bowl-shape valve, on the cover board have with the little liquid outlet of the intracavity inter-connection of bowl-shape valve and by the pipeline that is provided with little control valve and be connected with liquid outlet.
According to such scheme, when needs are opened valve, little control valve is opened, ducted liquid entered liquid entering hole and promote the upper end-hole that bowl-shape valve breaks away from liquid entering hole under the effect of fluid pressure this moment, making liquid enter liquid outlet flows out, simultaneously the liquid in the liquid entering hole through open check plate under little liquid inlet pipe and the pressure and enter in the bowl-shape valve insertion at liquid and enter liquid outlet by the road after flow out, thereby realize opening the task of valve.When the needs throttle down, little control valve is closed, the liquid that enter in the bowl-shape valve this moment flows out no longer by the road, when liquid is full of bowl-shape valve insertion, when fluid pressure equates with fluid pressure in the liquid entering hole in its bowl-shape valve insertion, bowl-shape valve port will be located on the liquid entering hole, thus sealing liquid entering hole and realize the task of throttle down.In said process, as stopping feed flow suddenly, the liquid in the water pipe flows backwards, paddle is not as closing at this moment, and refluence liquid flows in the bowl-shape valve insertion through little control valve, and safety check cuts out little liquid inlet pipe under the effect of refluence power, make bowl-shape valve expansion closing gate, thereby realize the task of non-return.Owing to taked technique scheme, the utlity model has following evident characteristic: the one, owing to adopted the technological scheme of little control valve control valve switch, so have easy operating, need not to be equipped with power plant, and adaptation is to the manual control valve on large flow pipe road; The 2nd, owing to adopted the technological scheme of the bowl-shape valve port of elasticity, existing all kinds of employing spirals promote or the technological scheme of landing flashboard has characteristics simple in structure, low cost of manufacture; The 3rd, because valve port has adopted soft compounding technique scheme, so have good seal performance, long service life and characteristics for ease of maintenaince.The 4th, be the structure of one owing to taked switch valve and safety check, so not only have the function of switch valve but also have the function of safety check.Can effectively realize task of the present utility model in sum.
Below will be with reference to the accompanying drawings that the utility model is described in further detail is as follows.
Accompanying drawing has provided structural representation of the present utility model.
In the accompanying drawings, 1 be liquid entering hole, 2 for control mouthful, 3 for flange plate, 4 for holding down bolt, 5 for cover plate, 6 for little liquid outlet, 7 for little control valve, 8 for pipeline, 9 for little liquid inlet pipe, 10 for bowl-shape valve, 11 for liquid outlet, 12 for flashboard, 13 for check plate, 14 for valve port, 15 for support, 16 for pilot hole.
With reference to the accompanying drawings, one end is that liquid entering hole 1 the other end is to have to have on the upside outer wall of valve body of liquid outlet 11 to be an angle and control mouth 2 that flange plate 3 is arranged with valve body, in the inboard of control mouthfuls 2 along being connected with the valve port 14 that has angle with valve body on the ring wall of liquid entering hole, on the flange plate 3 on this control mouth 2, be located in the bowl-shape valve 10 that useful elastic material is made, the base part seat of bowl-shape valve 10 drops on the valve port 14, and its liquid entering hole 1 is cut off with liquid outlet 11 is two spaces, upside is positioned with flashboard 12 in the bottom of bowl-shape valve 10, on the bottom of bowl-shape valve 10 and flashboard, be provided with the little liquid inlet pipe 9 that can make liquid entering hole 1 and bowl-shape valve 10 intracavity inter-connections, little liquid inlet pipe 9 is sleeved in the pilot hole 16 on the support 15 that is positioned on the valve interior wall, being positioned with at the upside of flashboard can be with the elasticity check plate 13 of little liquid inlet pipe 9 blanking covers, be provided with cover plate 5 and by holding down bolt 4 this cover plate 5 and bowl-shape valve 10 be positioned on the flange plate 3 in the control mouthfuls 2 at the upside of bowl-shape valve 10, on cover plate 5, have with the little liquid outlet 6 of the intracavity inter-connection of bowl-shape valve 10 and by the pipeline 8 that is provided with little control valve 7 and be connected with liquid outlet 11.
