Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and detailed description.
As shown in figure 1, the utility model embodiment includes joint 1, water pipe 2, valve 3, short circuit 4, pressure gauge 5 and cover plate 6th, water draining cylinder 7, spring 8, shrouding 9.
Specifically, joint 1 is used to be connected to the cooling water pipeline of blast furnace cooling device.Preferably, joint 1 is quickly to connect Head.In general, blast furnace cooling device has an inlet valve and a flowing water Valve, inlet valve and cooling device it Between three-way valve is installed, so as between soft water and industry water switch.When whether certain cooling device of hunting leak damages, incite somebody to action this The joint 1 of embodiment is connected with the triple valve, for leak detection.The specification size of joint 1 is selected according to actual needs, example Such as size is 1 cun half.
Water pipe 2 is used to transmit pressure to pressure gauge 5, and its one end is connected on joint 1, other end connection, installation pressure gauge 5.Preferably, water pipe 2 is seamless steel pipe, and specification size is selected according to actual needs, and such as external diameter is DN40.Pressure gauge 5 Measurement cooling water pressurize situation, if the pressure release of pressure gauge 5, illustrates the cooling device leak;If the not pressure release of pressure gauge 5, explanation Cooling device is water-tight.The range of pressure gauge 5 is preferably 2.5Mpa.
The middle part of water pipe 2 is connected by short circuit 4 with valve 3.That is, the one end of short circuit 4 is connected to water pipe 2, the other end It is connected to valve 3.Preferably, short circuit 4 is made up of the steel pipe of DN16;Valve 3 is ball valve, and specification is 1/2 ".When measured When cooling water pressure is close to 5 range of pressure gauge, the pressure release of valve 3 is opened, to protect the present embodiment.
When pressure gauge 5 is damaged, measures inaccurate, or without the opening pressure release of valve 3 in time, it would be possible to cause this to implement Example is damaged, in consideration of it, the present embodiment also includes safeties, it mainly includes cover plate 6, water draining cylinder 7, spring 8 etc..
Wherein, water draining cylinder 7 is cylindrical in shape, and the side wall of water pipe 2 is provided with the first delivery port 20, and one end of water draining cylinder 7 is fixed on On first delivery port 20, the side wall of water draining cylinder 7 is provided with the second delivery port 70.Cover plate 6 is movably disposed in water draining cylinder 7, tool There is relative first surface 61, second surface (unmarked), the area on water pipe axial direction of first surface 61 is more than the first delivery port 20 area, and first surface 61 correspond to the first delivery port 20, for the first delivery port 20 of covering.Spring 8 is located at and sluices In cylinder 7, and set along the axis of water draining cylinder 7, the second surface in cover plate 6 is supported in one end, and the other end is fixed.Spring 8 drives lid Being covered on the first delivery port 20 tightly of plate 6, when the internal pressure of water pipe 2 is excessive, hydraulic pressure will drive cover plate 6 to open and compress Spring 8, current will flow out along the first delivery port 20, the second delivery port 70.
Preferably, the first surface 61 of cover plate 6 is arcwall face.The other end of water draining cylinder 7 is provided with for blocking water draining cylinder 7 Shrouding 9, the other end of spring 8 is supported in the inner surface of shrouding 9.
