Abstract
The utility model relates to a long-distance transmission one-way flow valve which comprises a valve body, a valve deck and a valve element. The valve body can be installed between fluid pipelines in a serial mode. The valve deck is installed at the upper opening end of the valve body in a covering mode. The valve element is arranged on the portion of a valve port between the inlet section and the outlet section of the valve body in a pressing and sealing mode. A locating pipe with an inner sliding hole is arranged under the valve deck in a connecting mode. The valve element is provided with an ejector rod, wherein a half of the ejector rod extends into the inner sliding hole of the locating pipe of the valve deck. The upper end of the ejector rod is provided with a magnet or a magnetic material. The valve deck is provided with a Hall induction device. When the valve element presses and seals the valve port of the valve body, the Hall induction device outputs low level, and when the valve element is lifted and separated from the valve port of the valve body, the magnet or the magnetic material is lifted to enable the Hall induction device to output high level. According to the long-distance transmission one-way flow valve, the valve element is provided with the magnet or the magnetic material, the Hall induction device is installed outside the valve deck, and therefore long-distance transmission of the opening and closing states of the valve is achieved through the way that the Hall induction device senses the change of a magnetic field on the valve element.
Description
Technical field
The utility model belongs to liquid flow-conditioning technical field, relates to a kind of teletransmission one-way flow valves.
Background technique
At present, on market, existing a lot of one-way flow valves products are used for all kinds of fluid lines, but existing one-way flow valves does not all have valve state indicating device, and can not provide valve to user is to open or demonstration in off position.
Model utility content
The purpose of this utility model is that the problem that prior art is existed solves, and the teletransmission one-way flow valves of a kind of novel structure, easy to use, the remote transmission function that can realize valve state is provided.
For achieving the above object and the technical solution adopting is such: the teletransmission one-way flow valves providing comprise one can the valve body between fluid line in tandem, one mounts cover at the valve gap of valve body end suitable for reading and the spool at press seal valve port place between valve body entrance and outlet section, under valve gap, be provided with the positioning pipe of slide opening in one section of band, on spool, be provided with one and can partly stretch to the push rod in slide opening in valve gap positioning pipe, be placed with a magnet or magnetic material in push rod upper end, on valve gap, be provided with a hall sensing device, in the time that spool press seal is lived the valve port of valve body, hall sensing device output low level, in the time that spool lifts away from the valve port of valve body, magnet or magnetic material position liter move and make hall sensing device output high level.
Technical solution of the present utility model is also: described hall sensing device adopts the hall sensing device being made up of 3144 Hall transducers and LM393 voltage comparator.
Working principle of the present utility model is as described below.
In the time not having liquid to flow into from valve body entrance or from outlet, due to the effect of spool deadweight or liquid back-pressure, spool is sealed on valve port of valve body position.At this moment, because magnet or magnetic material and hall sensing device have certain distance, the sensing element induction of hall sensing device is less than the effect in magnetic field, and hall sensing device output low level, represents not have liquid flowing state.
There being liquid out-of-date from inlet streams, due to liquid effects, by spool jack-up, at this moment, magnet or magnetic material move up, and the sensing element of hall sensing device senses the effect in magnetic field, and hall sensing device is finally exported high level, indicates liquid flowing state.So just can realize the remote transmission of valve state.
Compared with prior art, the utility model by filling magnet or magnetic material and the mode of hall sensing device being housed in valve gap outside on spool, by the variation in magnetic field above hall sensing device induction spool, realize the remote transmission of valve opening and closed condition, product has the advantages such as novelty simple in structure, fabricating cost are low, convenient maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Fig. 2 is the schematic diagram of hall sensing device.
In figure, the title of each label respectively: 1-hall sensing device, 2-valve gap, 3-magnet or magnetic material, 4-valve body, 5-spool.
Embodiment
Below with reference to accompanying drawing, the utility model content is described further, but actual fabrication structure of the present utility model is not limited in embodiment shown in the drawings.
Referring to accompanying drawing, teletransmission one-way flow valves described in the utility model comprises the one-way valve being made up of valve body 4, spool 5 and valve gap 2, the positioning pipe of slide opening in valve gap is provided with one section of band for 2 times, on spool 5, be provided with one and can partly stretch to the push rod in slide opening in valve gap positioning pipe, be placed with a magnet or magnetic material 3 in push rod upper end, corresponding on valve gap 2, be provided with a hall sensing device 1.As shown in Figure 2, it is made up of 3144 Hall transducers and LM393 voltage comparator the structure of hall sensing device 1, when work, by induction spool 4 variation in magnetic field above, realizes the remote transmission of valve opening and closed condition.
The practical work process of this teletransmission one-way flow valves is such: in the time not having liquid to flow into from valve body entrance or from outlet, because spool 5 is conducted oneself with dignity or the effect of liquid back-pressure, spool is positioned at shown position.At this moment, because magnet or magnetic material 3 and hall sensing device 1 have certain distance, the sensing element 3144 of hall sensing device 1 is responded to the effect less than magnetic field, and 3144 3 pin outputs are through shaping circuits, final out output low level, represents not have liquid flowing state; When there being liquid out-of-date from the inlet streams of valve body 4, due to liquid effects, by spool 5 jack-up, at this moment, magnet or magnetic material 3 move up, and the sensing element 3144 of hall sensing device 1 senses the effect in magnetic field, and 3144 3 pin outputs are through shaping circuit, final out output high level, indicates liquid flowing state.So can realize the remote transmission of valve state.
