Abstract
The utility model relates to a device for indicating valve positions, which is provided with a casing made of metal or plastic, wherein transparent glass is inlaid on the upper part of the casing, and two limit switches for indicating the fully closed state and the fully opened state of the valve position, a miniature light bulb with low voltage and a wiring terminal are arranged in the casing. The utility model is installed on a butterfly valve or a ball valve, the valve position is indicated on site by a pointer arranged on a valve driving head, and the tail part of the pointer can collide with the limit switches at the fully closed position and the fully opened position. After the switches work, a signal is remotely transmitted to a control room or a fire-fighting center by the wiring terminal and a conducting wire. The device for indicating valve positions is widely used for pipeline systems in industrial production and fire-fighting systems of edifices, and can be used for the site observation and the remote monitoring of the closing states and the opening states of the valves in the systems.
Description
The utility model belongs to a kind of Thermal Automation instrumentation, but relates to a kind of both in situ observation valve position, again can be with the valve position signal device of complete shut-down and standard-sized sheet the signal is far passed.
In the firemain system of industrial pipe-line system and building, need that state is opened in the pass of each valve and carry out in situ observation and remote monitoring in the control room.
For achieving the above object, the utility model is taked following design proposal: the valve position signal device that is installed on butterfly valve or the ball valve is made up of metal or plastic casing, and top studs with clear glass; Two limit switches, low pressure micro lighting bulb and the tenminal block of reaction valve position complete shut-down, standard-sized sheet are housed in it; Rotating pointer is housed on the valve driving head, and the afterbody of this pointer and the collision of above-mentioned two limit switches are joined, and two limit switches are connected with tenminal block.
This valve position signal device simple in structure, part is few, volume is little, low price, be convenient to install and maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model plan view
Fig. 2 is the utility model plan view
Fig. 3 is that application circuit of the present utility model is given an example
From Fig. 1, Fig. 2 as can be known, the valve position signal device that is installed on butterfly valve or the ball valve is to make shell 1 by metal or plastics, and two limit switches 2, valve position low pressure micro lighting bulb 3, tenminal block 4 (can be loaded in the shell or shell outer) of reaction valve position complete shut-down, standard-sized sheet are housed in the shell.Rotating pointer 5 is housed on the valve driving head, and the afterbody of pointer 5 collides two limit switches in rotation.Two limit switches 2 of above-mentioned complete shut-down, standard-sized sheet are connected with tenminal block 4 respectively.
Fig. 3 is the circuit diagram of a kind of embodiment of valve position signal device, among the figure: QL-recloser, two limit switches in SQ1, the SQ2-valve position signal device, HG-greensignal light, HR-red eye, HW-valve position guidance lighting lamp, T-lighting transformer.When if supply voltage adopts the 6-12V direct current, transless T then.
As shown in Figure 3, when field personnel's control valve was opened, the pointer 5 on the valve driving head can indicate valve position.Pointer afterbody collision standard-sized sheet switch, after the switch motion and by tenminal block and conductor signal teletransmission to the control room; Otherwise when valve closing, equally also the signal of throttle down can be reached the control room.Therefore can monitor effectively that in the control room state is opened in the pass of each valve in the pipe-line system.
