Abstract
The invention discloses a combined air valve with a detachable inspection access. The combined air valve comprises a middle vertical post, and both the upper end and the lower end of the middle vertical post are provided with frames. The combined air valve is characterized in that a plurality of valve shafts are symmetrically arranged in the frames at the upper end and the lower end of the middle vertical post, a blade is sleeved between each pair of valve shafts, the valve shafts are connected with connecting rods, connecting plates are symmetrically arranged on two sides of each blade, a detachable blade I and a detachable blade II are symmetrically arranged on each connecting plate, and the blades, the connecting plates, the detachable blades I and the detachable blades II are connected through connectors. The combined air valve has the advantages that short time for detachment, convenience in resetting, convenience for working staff to complete daily maintenance.
Description
Technical field
The present invention relates to a kind of leafy air-valve, relate in particular to a kind of band dismountable type access path combined type air-valve.
Background technology
The combined type air-valve is used for running tunnel ventilation system, larger air channel, the large system in station cross section, is the capital equipment in subway, the tunnel ring control ventilation system, is the critical piece of realizing various ring control air vent modes and emergency ventilation.In paying a return visit, product user recognizes a problem, according to subway, tunneling personnel reflection, conventional combined type air valve blades is non-dismountable after installing, and lacks access path, in running into accident and at ordinary times regular maintenance, it is very difficult that the another side that the staff will enter air-valve carries out operation.The maintenance personnel will arrive the opposite side operation of air-valve, need to pull down whole transmission mechanism, link rod governor motion, monomer air-valve, need the professional to dismantle and the installation that resets, and the time is long, requirement is high, are very much inconvenient.Therefore, need a kind of new technology to solve this problem.
Summary of the invention
The purpose of this invention is to provide a kind of band dismountable type access path combined type air-valve.
The technical solution used in the present invention is:
A kind of band dismountable type access path combined type air-valve, comprise central post, the up and down two ends of described central post are provided with frame, symmetrically in the described upper and lower side frame be provided with a plurality of valve shafts, all be socketed with blade between described every pair of valve shaft, described valve shaft is provided with connecting rod, the monosymmetric brace that is provided with of described blade, described brace is monosymmetric to be provided with and to shirk the blade I and shirk the blade II, described blade, brace, shirks the blade I and shirks between the blade II and fix by connector.
The number of described valve shaft is 8-10.
The number of described blade is 8-10.
The described blade I of shirking is three blades with the span of shirking the blade II.
Described connector is connecting bolt.
Advantage of the present invention is: disassembly and assembly time is short, resets conveniently, is convenient to the staff and carries out daily maintenance.
