Abstract
A three-way valve for a large pipeline comprises a shell. A gas inlet (11), a first gas outlet (12) and a second gas outlet (13) are formed in the shell. The axis of the first gas outlet is perpendicular to the axis of the second gas outlet. A valve plate (2) is arranged in the shell. The three-way valve is characterized in that protection sleeves (31) are arranged around the outer walls of the head ends of the first gas outlet and the second gas outlet, a groove (33) is formed in the periphery of each protection sleeve, an opening of each groove faces towards the interior of the shell, and rubber pipes (32) connected end to end are arranged in the protection sleeves and provided with gas nozzles (34). High-pressure air is injected into the rubber pipes so that the rubber pipes can make full contact with the valve plate, and the reliable sealing between the gas outlets and the valve plate is achieved; the consumption volume of the high-pressure air is quite low. Compared with the prior art, it is ensured that energy can be saved and the manufacturing difficulty of the valve can be lowered on the basis of sealing.
Description
Technical field
The present invention relates to a kind of large-scale pipeline triple valve, it comprises housing, and housing is provided with suction port and two air outlets, and one of them opens another closedown to make described air outlet during valve plate action.
Background technique
Large-sized boiler needs to carry out purified treatment to its flue gas, and the flue of boiler is provided with three-way valve, and usual three-way valve makes flue be communicated with purifying processing device, closes between flue and chimney; When purification plant needs to safeguard, three-way valve makes flue be communicated with chimney, closes between flue and purifying processing device.Because the Contact of valve plate and air outlet is rigid contact, it is uneven to there is microcosmic in its surface of contact, and flue gas can leak; If any the leakage of flue gas when especially closing between flue and purifying processing device, can damage maintenance staff's health.For preventing the leakage of flue gas, valve plate generally adopts double layer construction, in the cavity of valve plate bilayer, input high-pressure air, and the pressure of high-pressure air is greater than the pressure in flue, and high-pressure air forms air curtain at the periphery of valve plate, stops that flue gas leaks from the outlet of valve.Its deficiency is, the high-pressure air amount of consumption is large.
Summary of the invention
The present invention wants technical solution problem to be to provide a kind of large-scale pipeline triple valve, and it can reliably to the sealing realizing valve, and the high-pressure air amount of consumption is little, can reduce the manufacture difficulty of valve.
Large-scale pipeline triple valve of the present invention, comprise housing, housing is provided with air outlet 13, suction port 11, first air outlet 12, second, first air outlet is mutually vertical with the axis of the second air outlet, be provided with valve plate 2 in housing, valve plate rotation 90 degree makes the first air outlet open or close, makes the second air outlet close or open; It is characterized in that, respectively around being provided with sheath 31 on the head end outer wall of the first air outlet and the second air outlet, girth along sheath has groove 33, the opening direction of groove is towards the inside of housing, the rubber pipe 32 of end-to-end is provided with in sheath, rubber pipe is provided with air nozzle 34, fills rubber pipe and valve plate can be made to be affixed with high-pressure air to rubber pipe.
Feature of the present invention is, when closing one of them air outlet, filling rubber pipe can make rubber pipe fully contact with valve plate with high-pressure air, and during contact, can to fill up the microcosmic on valve plate surface uneven for the elasticity of rubber pipe, realizes the reliable sealing between air outlet and valve plate; Due to rubber pipe closing high-pressure air, the consumption of high-pressure air is reduced greatly; In addition due to the extensibility of rubber pipe and wherein air, the parallelism between valve plate and air outlet to be required and the control overflow of valve plate rotation angle can suitably relax, reduce the manufacture difficulty of valve.Compared with prior art this valve energy energy saving on the basis ensureing sealing, reduces the manufacture difficulty of valve.
