Abstract
The utility model relates to a signal gate valve, and namely a general standard rising-stem gate valve is added with an electric signal device. When the valve is operated, power on and off electrical signals corresponding to the opening and the closing state of the valve are output simultaneously. The signal gate valve is characterized in that a box-shaped electrical signal device is added to the lifting and driving part of the valve board of the rising-stem gate valve, the lower end surface of the lifting and driving nuts of a valve rod is added with a driving gear engaged with a driven gear in a signal box arranged at corresponding part, and the driven gear in the signal box is provided with a small lifting mechanism used for pushing a microswitch and reducing stroke proportionally. Therefore, when a hand wheel rotates to lift the valve board of the gate valve in order to simultaneously open and close the valve, the lifting mechanism in the signal box also lifts synchronously with small proportion and pushes the microswitch to output the power on and off electrical signals corresponding to the opening and the closing state of the valve. Sound and light alarm in a long distance or the opening and the closing state of the valve can be monitored via the electrical signals, the valve can not be closed due to mistake, and safety is ensured.
Description
The utility model relates to the Signal sluice valve in a kind of fire-fighting automatic sprinkling system.
At present, the general common manual valve that uses is as the service valve in the automatic sprinkling system, this valve is in normally open all the time when working at ordinary times in this system, only when maintenance or replacing sprinkler head, need close, Awaiting Overhaul after hours, reopen, the working state that keeps standard-sized sheet, but in actual use, after the discovery service work finishes, often (be easy to) forget a little valves are reopened, and this valve found by the difficult again what of mistake closing state, like this, in case fire alarm takes place, automatic sprinkling system could be worked dehydration, can not in time put out a fire to save life and property and leads to serious fire!
For avoiding above-mentioned danger, the utility model provide a kind of need by monitor screen just can in whole the high building fire fighting automatic sprinkling system that be situated between all maintenance valves open and close the Signal sluice valve of state.
The utility model Signal sluice valve reload signal device and realizing on the standard Outside screw stem rising through handwheel type gate valve.I.e. signal box of attaching on the portal frame below the gate valve operation handwheel is provided with small-sized screw rod lowering or hoisting gear and has the lifting cover of specific shape face in this box, put down by lifting and move the promotion sensitive switch and outwards export " leading to ", " breaking " electrical signal.Signal box inner screw lowering or hoisting gear exposes driven gear by one and drives, and driven gear is driven by the driving gear that is contained in handwheel rotation synchronously.Like this, when operation handwheel lift valve bar opens and closes valve, also driving interior small-sized lowering or hoisting gear of signal box and lifting overlaps synchronous small scale lifting and promotes sensitive switch work, outwards export corresponding valve by wiring terminal and open and close " leading to " of state, the signal of " breaking ", realize long-distance alarm or demonstration.
The one step explanation during to the utility model below in conjunction with drawings and Examples:
Fig. 1 is Signal sluice valve and signal box attachment positions figure, among Fig. 1, and (1) signal box, (2) standard Outside screw stem rising through handwheel type gate valve.
Fig. 2 is the utility model Signal sluice valve full-gear signal box cut-away view.
Among Fig. 2, (3) driving gear, (1) signal box, (4) driven gear, (5) leading screw, (6) pin, (7) lifting cover, (8) spline nail, (9) scaffold, (10) sensitive switch.
The lower end surface of the drive nut that rotates with the operation handwheel at the handwheel position of standard Outside screw stem rising through handwheel type gate valve installs driving gear (3) with screw, by scaffold (9) with (see figure 2) on the portal frame of signal box overall fixed what gate valve, make the driven gear (4) in the signal box keep engagement with driving gear (3), leading screw (5) in driven gear (4) and the signal box is connected as a single entity by pin (6), and on leading screw (5), be with the band box thread lifting cover (7), lifting cover (7) upper end is provided with the spline nail (8) that stretches into the vertical slotted eye of scaffold, make the lifting cover can only lifting, can not rotate.The lifting cover makes specific shape face, near specific shape face both sides, symmetry install two identical and through the sensitive switch (10) of electric parallel connection, again three terminal (common port, normally opened contact end and normally-closed contact end) after parallel connection are received three wiring terminals respectively.(contact capacity 24V/1A)
Like this, when operation gate valve handwheel, when gate valve opens and closes, drive driven gear (4) and leading screw (5) rotate together by driving gear (3), thereby make lifting cover (7) do corresponding lifting and promote sensitive switch (10) action and outwards export and open and close with gate valve that corresponding position " leads to ", " breaking " electrical signal by specific shape face.The characteristic of output signal is example by the shape face decision that lifting puts with the utility model, and output signal characteristics is as follows:
When if gate valve opens and closes, the total travel of valve rod is that X(sees Fig. 2)
Standard-sized sheet position gate valve opens and closes total travel full cut-off position
Output signal can have two kinds of usings method:
All use 2, two kinds of contacts of method, with normally opened contact control red eye; With normal valve contact control greensignal light, like this, valve wide open shape greensignal light Chang Liang (red eye does not work) at ordinary times, in case valve is closed at 1/4 o'clock, red eye is bright, greensignal light goes out.
Above-mentioned two kinds of methods can be selected for use flexibly according to usage requirement and condition.
Owing to adopted technique scheme, the valve phenomenon is opened in the leakage that has overcome after service work finishes, in case avoid catching fire owing to valve mistake in the fire-fighting automatic sprinkling system is closed the serious fire accident of bringing, further improved the safety reliability of automatic sprinkling system.
Claims (2)
1, a kind of Signal sluice valve, form by standard Outside screw stem rising through handwheel type gate valve and additional signal device, the drive nut lower end surface of actuate valve stem lifting that it is characterized in that the operation handwheel center portion of what standard Outside screw stem rising through handwheel type gate valve on the throne installs driving gear (3) additional, and with signal box (2) in driven gear (4) engagement, gear (4) has pin (6) to be connected as a single entity with leading screw (5), on leading screw (5) top lifting cover (7) is housed, the upper end of lifting cover (7) is provided with spline nail (8), and spline nail left end stretches in vertical slotted eye of scaffold (9).
2, Signal sluice valve according to claim 1, it is characterized in that lifting cover (7) both sides are respectively equipped with that two symmetries are installed and electric on carry out sensitive switch (10) in parallel, the wheel trolley of two sensitive switches and lifting cover shape are in the face of claiming that by touching being moved up and down by the lifting cover promotes a pair of sensitive switch synchronous working.
