Abstract
The utility model discloses an airduct air volume control connector for tunnel construction and solves the problems that air volume required by two operating faces of a tunnel construction ventilation pipe in two directions cannot be reasonably distributed resulting in waste of energy consumption and extension of ventilation time. The bottom surface and the top surface of a tee joint composed of one main joint and two sub-joints are provided with arc grooves, flexible air volume dampers are arranged in grooves in the bottom and top surfaces and connected to control rods, and the flexible air volume dampers are controlled through control valves to slide in the grooves so as to change the size of ventilation area of the sub-joints. The airduct air volume control connector which is economical, reasonable and energy-saving has the advantages of reasonable and reliable structural design, and part of equipment purchase cost and daily energy consumption cost can be saved.
Description
Technical field
The utility model relates to a kind of constructing tunnel air quantity controller, specifically relates to a kind of constructing tunnel wind tube wind quantity control connection device.
Background technology
Tunnel inclined shaft, horizontal hole construction bi-level mode, is mainly comprised of the connecting tube (threeway) between high-power blower, main pipeline, branch pipe(tube), primary branch road outside hole etc., and connecting tube is generally connected firmly main pipeline and branch pipe(tube).When Tunnel Inclined Shaft Construction ventilates, be divided into intensified ventilation and continue the two kinds of basic models of ventilating, when the operation constructions such as explosion, muck removal, sprayed mortar, work plane is seriously polluted, air worsens, need to adopt the intensified ventilation of Wind Volume, the concentration of pernicious gas and dust in dilution hole, improves the air quality condition of operating area in time; When other operation construction, owing to not producing pollution, adopt the lasting ventilation of little air quantity, can meet the demand of constructor to fresh air.The intensified ventilation time is shorter, and lasting ventilation time is longer.
After tunnel inclined shaft, horizontal hole driving certain length, all can open up two scope of operations simultaneously, can manual control and adjust the construction speed of two work planes, when a work plane need to continue to ventilate and another work plane while needing intensified ventilation, equivalent divides wind can cause lasting ventilation operation face air quantity waste, and intensified ventilation face air volume is not enough, intensified ventilation time lengthening, affects the normal linking of operation, and wastes energy consumption, delay duration.Existing threeway linker effect when regulating different operating face air force is all obvious not, and energy consumption waste is comparatively serious.
Summary of the invention
The purpose of this utility model is in order to have overcome deficiency of the prior art, ventilating duct air quantity control connection device for a kind of constructing tunnel is provided, solves ventilating duct both direction work plane Air Quantity Required in existing tunnel construction and can not get the problem that reasonable distribution causes ventilation time prolongation and waste energy consumption.
In order to address the above problem, the utility model is achieved through the following technical solutions: ventilating duct allocation of the amount of air connector for constructing tunnel, comprise major joint, a joint, arc groove and air quantity control baffle plate, major joint becomes the capable connection of Y with two joints, and a joint bottom surface and end face are provided with arc groove; Described groove is divided into the control groove that does not affect the deposit of air quantity groove and affect air quantity, in deposit groove, be placed with air quantity and control baffle plate, air quantity is controlled baffle plate and is connected on control lever, control lever is controlled down and is slipped into control groove by control valve, props up the size adjustment air quantity of joint draught area by change.
It is flexible encapsulated thin plate that described air quantity is controlled baffle plate, and toughness is better, flexible.
Described deposit groove is equal with the corresponding arc length of control groove, and shape is identical.
Described deposit groove and control in groove and be provided with rubber weather strip, prevents the object of leaking out to reach.
The utility model reasonable in design is reliable, realized the reasonable distribution of constructing tunnel one drag two ventilation both direction work plane Air Quantity Required, and can rationally adjust under the prerequisite of Design of ventilation, suitably reduce the power of ventilation equipment, the elasticity system that can realize tunnel inclined shaft, the construction of horizontal hole is simultaneously ventilated, there is economy, reasonable, energy-conservation, save equipment component acquisition expenses and daily energy consumption cost.

Fig. 3 is this practical new 1-1 cross section elevation cross-sectional view;
Fig. 4 is the enlarged drawing that this practical resh air requirement is controlled baffle part.
The specific embodiment
See Fig. 1-4, in figure: major joint 1, a joint 2, control valve 3, arc groove 4, air quantity are controlled baffle plate 5, control lever 6
Ventilating duct air quantity control connection device for constructing tunnel, comprises major joint 1, a joint 2, arc groove 4 and air quantity control baffle plate 5, major joint 1 and two the capable docking of 2 one-tenth Y of joint, and joint 2 bottom surface and end face are provided with arc groove 4; Groove 4 is divided into the control groove 4b that does not affect the deposit of air quantity groove 4a and affect air quantity, in deposit groove 4a, be placed with air quantity and control baffle plate 5, air quantity is controlled baffle plate 5 and is connected on control lever 6, control lever 6 is controlled down to slip into by control valve 3 and is controlled groove 4b, by change, prop up the adjusting of any air force of realization of joint draught area, control valve 3 at the two ends of deposit groove 4a respectively corresponding corresponding joint complete and ventilate with stuffy, when air quantity control baffle plate 5 slides to major joint 1, it is large that air quantity becomes, until maximum; When air quantity is controlled baffle plate 5 and slided to joint 2, air quantity diminishes, until stuffy.
Deposit groove 4a is equal with the corresponding arc length of control groove 4b, and shape is identical.Deposit groove 4a and control in groove 4b and be provided with rubber weather strip, prevents the object of leaking out to reach.It is aluminium alloys matter flexible encapsulated thin plate that air quantity is controlled baffle plate 5, and toughness is better, flexible.
