Accompanying drawing explanation
Accompanying drawing 1 is the main TV structure schematic diagram of the utility model;
Accompanying drawing 2 is the side-looking structural representation of accompanying drawing 1.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of hose valve, comprise valve body 2, flexible pipe 5 is provided with bottom valve body 2, motor 1 is fixedly equipped with in described valve body 2 upper end, the motor shaft 3 of this motor 1 extends in valve body 2, and the end attaching of this motor shaft 3 has last item 4, and flexible pipe 5 is positioned between last item 4 and valve body 2 bottom surface.Motor 1 is with and dynamic pressure shaft 4 is moved or moves down, and when last item constantly moves down, can oppress flexible pipe; Then flexible pipe is loosened when last item moves.
The sidewall of valve body 2 is provided with upper limit position switch 7 and lower position switch 6, last item 4 is positioned at the region between the upper limit position switch 7 of valve body 2 and lower position switch 6.Wherein upper limit position switch is arranged on the body wall region above flexible pipe, and lower position switch is arranged on bottom body wall, usually all in the sidewall locations that the bottom of flexible pipe is corresponding, is urged to flexible pipe when last item is moved down, and realizes the closedown cutout of flexible pipe.Last item can only move in the region between upper bit switch and lower position switch.Further, in order to better ensure processing, assembly precision, upper limit position switch and lower position switch are arranged on the same sidewall of valve body.
In addition, valve body 2 sidewall is provided with guide groove 10, and last item 4 activity is contained on this guide groove 10, and last item 4 moves up and down along this guide groove 10.This guide groove 10 is generally all be arranged between upper limit position switch 7 and lower position switch 6.
Last item specifically open shape, in this and indefinite.Usually last item can be designed to cylindrical, now last item is a cylindrical tube.Or rectangle, now last item can regard a pressing plate as.Or other can realize by flexible pipe compressing cutout open shape, do not enumerate at this.In the present embodiment, last item is cylindrical.
In addition, motor 1 is arranged on valve body 2 top, is convenient to dismounting, convenient installation.
The utility model is particularly useful for low pressure foul sewer system, as a kind of control valve, in the water circuit system that foreign material are more, can effectively ensure the unimpeded of valve, extends maintenance time.Flexible pipe one end and sewage pipe attaching, the flexible pipe the other end then causes pollution discharge pond or other regions.When not needing throttle down, last item to be positioned at above flexible pipe and to be blocked by upper limit position switch, and now flexible pipe loosens, and fluid circulates smoothly in flexible pipe, owing to being straight-through tube, therefore, even the foreign material such as hair are also not easy to result in blockage.When needs throttle down, driven by motor last item moves down, and along with constantly moving down of last item, flexible pipe is subject to the compressing of last item and produces distortion, and flexible pipe is blocked, thus fluid cannot be flow through from flexible pipe, realizes the closedown of valve.Owing to being subject to the restriction of lower position switch, last item can be stopped by lower position switch, and when last item is pressed to lower position switch position flexible pipe, motor stops operating, and stops continuing to press down.
In addition, upper limit position switch and lower position switch, except playing except position-limiting action to last item, also have other effects.Because the motor chosen has specified moment, actual moment or actual maximum moment can different (if moment when temperature raises reduces) according to specific environment.When resistance torque is greater than the maximum moment of motor, motor meeting stall, now motor cannot open or close.If do not have limit stoper, when such as compressing, motor can run always (even if no longer continuing to compress to last item during stall); During compression, flexible pipe, valve body etc. all have distortion, this distortion can feed back on motor shaft with the form of resistance torque, when now needing to open valve, need larger moment just can overcome resistance torque and then open valve, but now due to motor rotation blockage, motor temperature raises, moment (maximum moment) reduces, so now motor reversal last item also cannot rise, cause valve of not opening.And lower position switch can prevent motor generation stall situation, when guaranteeing motor forward and backward, last item can normally move up and down, and position limit device also has above-mentioned situation.Lower caging device can also avoid crossing of flexible pipe to compress simultaneously; Cross the damage that compression can cause flexible pipe, the shortening of hose life.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
