Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, a valve having a signal generating function includes a valve body 6; a worm gear case 3 is fixedly arranged above the valve body 6, the horizontal input end of the worm gear case 3 is connected with a hand wheel 1 through a hand wheel rotating shaft 2, the vertical output end of the worm gear case 3 is connected with a valve shaft 4 vertically arranged in the valve body 6, and a disc plate 5 is arranged on the valve shaft 4; the bottom end of the valve shaft 4 is arranged in the base of the valve body 6, the bottom end of the valve shaft 4 is provided with a positioning bulge 41, the base of the valve body 6 is provided with an installation groove hole, and a position indicating device 7 is arranged in the installation groove hole;
the position indicating device 7 includes: a pressing block 71 and a waterproof microswitch 72; the pressing block 71 is trapezoidal, the bottom surface of the pressing block 71 is fixedly connected with a contact of the waterproof microswitch 72, and the periphery of the outer surface of the waterproof microswitch 72 is provided with an annular bulge 73 which is hermetically welded with the inner wall of the mounting groove hole; the upper surface of the pressing block 71 protrudes out of the inner end of the mounting groove hole, the position of the pressing block 71 corresponds to the position of the positioning protrusion 41 when the disc plate 5 is closed, and the bottom surface of the waterproof microswitch 72 is provided with a wiring port.
In the practical application of the utility model, the field operator rotates the hand wheel 1 to rotate the valve shaft 4 in the valve through the worm gear case 3, thereby driving the disc plate 5 to rotate, when the disc plate 5 rotates to approach to the closed position, the positioning protrusion 41 at the bottom end of the valve shaft 4 starts to contact with the trapezoidal inclined surface of the pressing block 71 of the position indicating device 7, gradually pressing down the pressing block 71, when the disc 5 reaches the closed position, the pressing block 71 is pressed down to the right position, the waterproof microswitch 72 is activated, the waterproof microswitch 72 outputs a signal to the pipeline network management and control system, at this time, the pipe network management system monitors that the manual valve is completely closed, and when the operator considers that the manual valve is closed, however, when the disc 5 is not completely closed due to a valve failure or carelessness of an operator, the pipeline network management and control system can find that the manual valve fails according to the fact that the waterproof microswitch 72 does not output a signal.
Because the pressing block 71 is designed in a trapezoidal shape, the two inclined surfaces in the trapezoidal shape ensure that the contact resistance can be reduced when the positioning protrusion 41 rotates to contact with the trapezoidal surface of the pressing block 71, and the blocking phenomenon is prevented.
As shown in fig. 1-3, a hand wheel 1 and a hand wheel rotating shaft 2 are fixed through a shaft pin.
As shown in fig. 1-3, a sealing ring is sleeved on the upper part of the valve shaft 4.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
