Abstract
The utility model discloses a gland heater multistage water seal device. The gland heater multistage water seal device comprises an installing seat and multiple water seal barrels arranged on the installing seat side by side. The upper end of each water seal barrel is communicated with a connecting barrel, wherein the connecting barrel is a barrel-shaped cavity with two closed ends, a partition plate is arranged in the middle of the barrel-shaped cavity and divides the connecting barrel into two independent cavities, and the top walls of the two independent cavities are respectively provided with a deflation valve. A water level valve is arranged on one side of each connecting barrel. An inlet and an outlet are respectively formed in side walls, on two end portions, of each water seal barrel. A water injection valve is arranged on one side, where the inlet is formed, of each water seal barrel. A connecting pipe is arranged between the two water seal barrels in the middle. The gland heater multistage water seal device is convenient to install, maintain and repair, and suitable for being popularized and used in a power plant.
Description
Technical field
The utility model belongs to water seal arrangement, specifically relates to a kind of energy-conservation gland heater multilevel water seal device.
Background technique
Gland heater is a kind of equipment that reclaims gland packing leakage that the power station generally uses, and is applicable to the power station that is equipped with water jet air ejector, can save steam, reduces energy consumption, reduces environmental pollution simultaneously.But at present the water sealing (sealing water) pipe that adopts of existing common gland heater condenses hydrophobicly to the pipeline of vapour condenser in equipment such as power plant's low-pressure heater gland steam cooler usually, and it is to rely on medium to carry out hydrophobic in water sealing (sealing water) pipe import and the pressure difference between exporting.Water sealing (sealing water) pipe normally uses the U-shaped water sealing (sealing water) pipe of the principle design of Communicating device.
Existing water seal arrangement is made up of two pipes than long UNICOM, so this water seal arrangement aspect ratio is higher, and equipment is installed relatively difficulty.In order to address this problem, often buried in underground a very long segment pipe when existing water seal arrangement is installed, because underground humidity is bigger, buriedly corrode easily at underground section of tubing, even rot to damage.Pipeline damages and can cause that on the one hand unit degree of vacuum descends, can cause that on the other hand the carbonated drink quality that enters vapour condenser is abominable, and influence the safe operation of unit, and buried when underground section of tubing rots the staff have no idea in time to judge and find, therefore also just can not in time take treatment measures and bring potential safety hazard for the safety in production of power plant.
The model utility content
The purpose of this utility model is to provide a kind of gland heater multilevel water seal device, and this device is installed, safeguarded and overhaul conveniently, is suitable for promoting the use of in power plant.
In order to achieve the above object, the utility model is achieved by the following technical solutions:
A kind of gland heater multilevel water seal device, comprise fitting seat, and be arranged on some water seal tubes that are set up in parallel on the fitting seat, the upper end of described water seal tube is communicated with connecting cylinder, connecting cylinder is the airtight tubular die cavities in two ends, middle part at the tubular die cavity is provided with dividing plate, and connecting cylinder is separated into two independent mould cavities, and the roof of two independent mould cavities is respectively arranged with a bleed valve; One side of described connecting cylinder is provided with water level valve; Water seal tube sidewall at two end part is respectively equipped with import and outlet, and the water seal tube of suction side is provided with water injection valve therein, is provided with connecting tube between two the water seal tubes in middle part.
Further, described water seal tube is six, and six water seal tubes are by the sealing of bottom fitting seat.
Further, described import is provided with inlet valve, and outlet is provided with outlet valve.
Further, the water injection valve height on the described water seal tube is lower than the height of import.
Compared with prior art, this water seal arrangement height reduces, and equipment is easy for installation, do not need part water seal tube is embedded in underground, convenient for installation and maintenance, easy access.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, import; 11, inlet valve; 2, outlet; 21, outlet valve; 3, water seal tube; 4, connecting cylinder; 41, dividing plate; 5, fitting seat; 6, connecting tube; 7, water injection valve; 8, bleed valve; 9, water level valve; 11, inlet valve.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the multilevel water seal device of this gland heater, comprise fitting seat 5, and be arranged on the water seal tube 3 that is set up in parallel on the fitting seat 5, be communicated with connecting cylinder 4 in the upper end of water seal tube 3, connecting cylinder 4 is the airtight tubular die cavities in two ends, is provided with dividing plate 41 at the middle part of tubular die cavity, and connecting cylinder 4 is separated into two independent mould cavities; Roof two independent mould cavities is respectively arranged with a bleed valve 8, is provided with water level valve 9 in a side of connecting cylinder 4; The water seal tube 3 of this device is four, and water seal tube 3 upper side walls at two end part are respectively equipped with import 1 and outlet 2, are provided with inlet valve 11 in import 1, and outlet 2 is provided with outlet valve 21; The water seal tube 3 of an end is provided with water injection valve 7 therein, is provided with connecting tube 6 between two the water seal tubes 3 in middle part.
The above-mentioned first water seal tube, the second water seal tube, the 3rd water seal tube, the 4th water seal tube, the 5th water seal tube and the 6th water seal tube bottom by fitting seat 5 sealings, the first water seal tube, the second water seal tube, the 3rd water seal tube, the 4th water seal tube, the 5th water seal tube with the top of the 6th water seal tube be connected with connecting cylinder 4 tubular die cavities, be communicated with by connecting tube 6 between the 3rd water seal tube and the 4th water seal tube.
During proper functioning, by water injection valve 7 unrestrained water is full of six water seal tubes 3, it is little to flow into the vapour condenser flow resistance, when unrestrained water is reduced to can not be full of six water seal tubes 3 time, water column in six water seal tubes 3 is no longer mobile, the vapour of shutoff equipment enters vapour condenser, avoids the loss of energy medium, prevents that condenser vacuum from destroying.
During use, close water seal inlet valve 11 and outlet valve 21, open water injection valve 7 and bleed valve 8, close water injection valve 7 after filling with water, open water level valve 9, put to not water outlet and close water level valve 9, open water seal outlet valve 21, slowly open inlet valve 11 and put into operation.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the protection domain that the utility model is determined by claims of submitting to.
