Description
Technical field
The present invention relates to a kind of air channel valve that is used to control and regulate the air pipeline air-flow.
Background technique
The air channel valve is a kind of device commonly used in the various air pipelines, and its fundamental function is the actual demand according to ventilation system, and blocking-up or complete opening air pipeline also can locally according to demand be opened in right amount fully, regulate the air flow rate that pipeline passes through to reach.At present, the modal form of this air-valve is the blinds air-valve, and air pipeline is closed, opened or local fundamental function of opening realizes by the synchronous rotations of organizing the blade different amount more.In the practical application of this class air-valve, have following deficiency: 1. leak out in the slit.Because the blinds air-valve is made of many groups blade, when air-valve cuts out, objectively certainly exist the slit of incomplete closure between the blade, and blade is many more, the slit is also many more, and its corresponding inleakage was also many more when air-valve cut out.When blast was high more in the pipe that bears, then the slit source air quantity also increased thereupon; 2. area is efficient lower.When air-valve is opened, the scale of construction external form of blade self will reduce the air-valve effective discharge area; 3. metal consumption and fabricating cost height.Closing the air-valve both sides, because the existence of pressure reduction, the air-valve blade need bear the formed pressure of this pressure reduction.In order to resist the deformation that blast causes, the air-valve blade is many to be made of rigid material, and the widest with the metallic material practicality.Blade in the practical application of air-valve, every group of single blade, a certain segment rectangle section of independent this air-valve of burden, the physical length on the long limit of its section rectangle becomes the key element of control whole valve body.Along with this length increases, the resistance to flexure requirement of blade material is also increased corresponding, the length on the long limit of blade rectangle is long more, and is also big more to the rigidity requirement real consumption also high, metal section of metal material.In other words, along with the increase of air-valve section, the metal consumptive material of air-valve will be non-linear rising.Correspondingly, the deadweight of air-valve, fabricating cost also will be non-linear rising.So that on the current market, the fabricating cost of large-scale air-valve and actual selling price, high so far; 4. aesthetic property is relatively poor.Because the function requirement of blinds air-valve has been determined the outward appearance typing of its device, even the external occasion of environmental beauty demand is being arranged, therefore blinds air-valve self can not change its external form, because of additional separately functional loss and economic cost attractive in appearance are inevitable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of curtain air-valve, has good airtight performance, and simple in structure, control operation is easy, and can reduce the cost of production of air-valve significantly.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Curtain air-valve of the present invention is characterized in that: it comprises flexible curtain and drives the drive unit of its folding and unfolding campaign, and the front side grid, the rear side grid that are fixedly installed on flexible curtain folding and unfolding plane of movement both sides.
In technique scheme, fixedly connected with spool in the upper end of described flexible curtain; Described drive unit comprises the line shaft that is installed in the spool below and drives this line shaft motor rotating; Described spool, line shaft are in transmission connection by driving mechanism.
The invention has the beneficial effects as follows, can be easily folding and unfolding campaign by flexible curtain, change the cross section that it blocks air pipeline, air pipeline is blocked or complete opening fully, perhaps can local according to demand an amount of the unlatching reach the air flow rate that the adjusting pipeline passes through; Compare with traditional blinds air-valve, have good airtight performance; Air-valve is opened, open the part, the control operation of close vent line is very easy; Flexible curtain is made with the noncombustible material fabric, can reduce the cost of production of air-valve significantly, and its economic benefit is more remarkable in the making of large-scale air-valve; Can satisfy the attractive in appearance demand of different use occasions easily and flexibly to the air-valve outward appearance.
