Detailed description of the invention
As depicted in figs. 1 and 2, be assembly structure schematic diagram and the cross-sectional schematic of long-range leakage alarm of the present utility model.As shown in the figure, the utility model provides a kind of long-range leakage alarm, this long-range leakage alarm comprises body 4, float switch 5, ball sealer 2, end cap 7, spring 3 and liquid flow hole a, body 4 comprises upper port 8 and lower port 9 two parts, end cap 7 is connected to upper port 8 place of body 4 by connecting thread e, end cap 7 can be fixed on upper port 8 place of body 4, also upper port 8 place can be arranged on removably, float switch 5 is arranged on the inside of body 4, and float switch 5 is threaded with end cap 7.Liquid flow hole a is arranged on lower port 9 place, the upper end of spring 3 is connected with the lower end of float switch 5, the lower end of spring 3 is connected with the ball sealer 2 of below, namely spring 3 has one end to be connected with float switch 5, float switch 5, spring 3 and ball sealer 2 are set in turn in body 4 according to order from top to bottom, float switch 5 is near the upper port 8 of body 4, and ball sealer 2 is near the lower port 9 of body 4.Lower port 9 place of body is provided with backing pin 1, spring 3, ball sealer 2 is loaded in the lower port 9 of body 4 successively, and inserts in limit pin hole d by backing pin 1, and backing pin 1 is assemblied on body 4 by limit pin hole d, can prevent ball sealer 2 from coming off like this.。
The side of body 4 is provided with near upper port 8 place to leak collects mouth f, this long-range leakage alarm also comprises drain stub 10, drain stub 10 is assemblied on body 4 by leaking collection mouth f, when there is leak of liquid, after liquid to flow into the height that after body 4, arrival is certain from liquid flow hole a, liquid can be collected mouth f and flow out from drain stub 10 by leaking, and liquid can not be caused to overflow cannot flow out thus finally result in greater loss.This long-range leakage alarm also comprises magnetic switch (not shown), this magnetic switch is arranged in the upper port 8 of body 4, magnetic switch is connected with outside warning device by switch wire h, overflow ducts 6 is provided with between ball sealer 2 and body 4, the lower end of float switch 5 is provided with step surface c, spring 3 is arranged on step surface c, and the internal orifice dimension of step surface is less than the internal diameter of spring.
Be screwed in tested device by this long-range leakage alarm by connecting thread, the necessary at right angle setting up and down of this long-range leakage alarm, guarantees that float switch 5 passes through the sagging falling bodies of deadweight under set condition, can not cause misoperation by trigger switch.
When tested device is in set condition, and when not leaking, the ball float of float switch 5 is in set condition under deadweight condition, and magnetic switch is not triggered, and alarm does not send alarm signal.
When tested device is in set condition, and there occurs leakage, now leakage liquid constantly flow to below the ball float of float switch 5 from ball sealer 2 and the overflow ducts 6 of body 4 by liquid flow hole a, ball float moves upward gradually under liquid buoyancy effect, trigger magnetic switch action, be communicated with warning device by switch wire h, final output alarm signal, when leakage continues, collect by leaking collection mouth.
When tested device in working order time, now operating pressure will act on ball sealer 2 from small to large, promote the elastic force that ball sealer 2 overcomes spring 3 and close overflow ducts rapidly.
In engineering test and practice, the utility model is energy action message all, and meets the requirement of design specification, and balance type proportioning mixer of the present utility model all can ensure in sizable pressure and range of flow that mixing ratio is stablized.
The utility model is for the hidden danger of known technology, according to the Research idea of function i ntegration, and the development philosophy of simple in structure and low in cost, Design of Main Structure is exquisite, simply and easily process, select several parts common on market to coordinate assembling with it simultaneously, it is arranged on system under test (SUT), automatically sending the function of alarm signal when making it to be provided with leakage, avoiding the property loss caused because of failing to discover leak of liquid in time.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
