Embodiment
Refer to Fig. 2, the gravity damped type water seal arrangement that the utility model the first embodiment provides comprises return pipe 101, shell 102 and sealing block 103; Vertically and being arranged on gland heater pipeline 203 of sealing, the top of return pipe 101 is stretched in shell 102, the top level of return pipe 101 for return pipe 101; Also vertical installation of shell 102, the bottom of shell 102 and return pipe 101 are tightly connected.Sealing block 103 is spherical, is placed in the top of return pipe 101, by sealing block 103 gravity, return pipe 101 is sealed; Top and the coagulator pipeline 204 of shell 102 sidewalls are tightly connected.The top of return pipe 101 is calculated design, precision machining as the case may be, and spherical sealing block 103 also needs to come according to specific needs designing and calculating, and precision machining guarantees that sealing block 103 and the top of return pipe 101 can be sealed and matched.In the present embodiment, the top of return pipe 101 exceeds the bottom 50mm of gland heater pipeline 203, and the diameter of shell 102 is 1.41 times of return pipe 101 diameters; Assurance is from the outflow of expanding smoothly of return pipe 101 water out, and spherical sealing block 103 diameters are greater than the internal diameter of return pipe 101, prevent from falling to being stuck in return pipe 101 after sealing block 103 less traction.Gland heater 201 is installed at the top of gland heater pipeline 203, and coagulator 202 is installed in the end of coagulator pipeline 204, and gland heater 201 is higher than coagulator 202.
The working procedure of this gravity damped type water seal arrangement is such: current flow into gland heater pipeline 203 from gland heater 201, flow to return pipe 101, and owing to there being sealing block Action of Gravity Field, water is enclosed in return pipe 101; Along with the lasting inflow of current, the buoyancy that current make progress to sealing block is greater than the gravity of sealing block self, and current are washed sealing block open, flows in shell 102; Water in shell 102 flows to coagulator pipeline 204 after amassing completely, flows into coagulator 202.This gravity damped type water seal arrangement, coagulator pipeline 204 is tightly connected with shell 102, and when water level is designated water level lower than the top of return pipe 101, sealing block, by return pipe 101 sealings, can not make the air in return pipe 101 flow into shell 102.
Refer to Fig. 3 and Fig. 5, the gravity damped type water seal arrangement that the utility model the second embodiment provides comprises whole features of gravity damped type water seal arrangement in the first embodiment.
In order to increase device, adapt to more applied environment, the adjustment screw 104 that extends to shell 102 inside that is provided with at the top vertical of shell 102, adjust screw 104 and be fixedly connected with one end of Regulation spring 105, the other end of Regulation spring 105 is fixedly connected with sealing block 103; The sidewall of shell 102 is provided with jacking screw 106, can jack-up sealing block 103 to the internal regulation jacking screw 106 of shell 102.In the present embodiment, the top of return pipe 101 exceeds the bottom 100mm of gland heater pipeline 203.
According to the needs of actual conditions, by Regulation spring 105, the adjusting of adjusting screw 104, can change the pressure of 103 pairs of return pipes 101 of sealing block, thereby regulate the water level in return pipe 101; Adjust screw 104 and directly draw, put operation Regulation spring 105, during operation, do not change the concentricity of sealing block 103 and return pipe 101.To shell 102 inside, screw jacking screw 106 can coagulator 202 without negative pressure or negative pressure when inadequate direct jack-up sealing block 103 open return pipe 101 and realize the current of low discharge and pass through, current flow to coagulator 202 under the effect of gland heater 201 and coagulator 202 water-heads.After coagulator 202 negative pressure are normal, unclamp and start jacking screw 106, whole device continues normal operation.
In shell 102, be provided with an annular canister 110, annular canister comprises upper and lower two annular slabs and the equally distributed rib 108 of three vertical annulars that connects two annular slabs, rib 108 is cylindrical, and the height of annular canister 110 is consistent with the height of shell 102 inside.These ribs 108 can be strengthened the intensity of shell 102, and the concentricity that limits from top to bottom sealing block 103 and return pipe 101 is qualified, guarantee that 103 times backwardnesss of sealing block can accurately be pressed on the top of return pipe 101, can not produce deviation.
Return pipe 101 is connected with gland heater pipeline 203 by flange 109, and shell 102 is connected with coagulator pipeline 204 by flange 109.The upper cover of shell 102 also adopts flange 109 to connect, and can take flange 109 apart and take out sealing blocks 103 when shutting down or overhauling, and the foreign material of cleaning shell 102 inside, check Regulation spring 105, adjust screw 104, jacking screw 106, return pipe 101 etc.Flange has good sealing effect, detachable mounted advantage.Whole device breaks down and can directly by flange 109 handle assemblies, pull down maintenance.
Gland heater pipeline 203 and coagulator pipeline 204 are provided with valve 205, and valve 205 is near flange 109.During maintenance, close two valves 205 can pull down flange 109 start maintenance.
Refer to Fig. 6, the gravity damped type water seal arrangement that the utility model the 3rd embodiment provides comprises whole features of gravity damped type water seal arrangement in the second embodiment, wherein sealing block 103 is circular dull and stereotyped, being connected with one heavily encircles 107 below for sealing block 103, heavily encircles 107 outsides that are placed on return pipe 101.Flat sealing block can simplification device, increases the spatial altitude at return pipe 101 and shell 102 tops.
In this embodiment, shell 102 sidewalls have two places to be connected with the upper and lower of coagulator 202 sidewalls by coagulator pipeline 204.Two coagulator pipelines 204 can increase flow area, reduce resistance.
The bottom of gland heater pipeline 203 is provided with sewage draining exit 206, can discharge dirt and the impurity of gland heater 201 inner alluvials by sewage draining exit 206.
The outside of gland heater pipeline 203 is provided with water-level gauge 207.Whether water-level gauge 207 is as the foundation that regulates water levels, can also judgment means work normal.
The sidewall of gland heater pipeline 203 is provided with inverted U-shaped pipe 208, and U-shaped pipe 208 tops are lower than the top of described gland heater pipeline 203.U-shaped pipe 208 does not fill valve 205 and directly passes into trench, prevents that gland heater 201 water levels are too high, not draining when the normal operation of device.U-shaped pipe 208 can guarantee under the interior negative pressure of gland heater 201, not to the interior blank gas of gland heater 201, can also to guarantee that working medium all reclaims.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
