The air volume regulating valve has the positive effects that the fan can reach any flow value in the changing flow range and has air flow prewhirl capacity, the energy consumption, air kinetic energy and static energy loss can be reduced, and the energy conservation and emission reduction are realized. The air volume regulating valve has the advantages of large ventilation area, smooth action and synchronous rotation, small required driving power and prewhirl generation to the air flow.
Description
Technical field
The present invention relates to a kind of fan delivery regulating valve, belong to blower fan control technique field.
Background technique
The volume damper door of background technique is divided into rectangle valve and circular valve by shape; Can be divided into bar shaped flapper valve and rectangle flapper valve by baffle type.The rectangle regulating valve only can use the bar shaped baffle plate, and this type of valve does not possess the ability that provides air-flow to prewhirl.Circular modulating valve can use bar shaped baffle plate and fan shape baffle, and bar shaped baffle plate shortcoming repeats no more; The fan shape baffle valve can provide the prewhirling of air-flow, but existing fan-shaped modulating valve has following two shortcomings: 1, fan shape baffle valve supporting baffle needs be provided with at the valve body center tap web body, and the tap web body not only takies flow area but also reduce the shortcoming of flow velocity in addition; 2. the fan shape baffle valve uses whole circle annulus to join short rotating handle driving; The transmission system reliability is low; The annulus rotation often taking place put in place and baffle plate rotation situation not in place, is the multiple relation because the rotating handle radius is short how much in the baffle plate required moment of same large-area baffle plate moment more required for the present invention simultaneously.
To sum up, the problem of background technique existence is: the air-flow of valve inner process is passed through under less kinetic energy rejection; Secondly the required moment of regulating and controlling valve events makes more greatly and baffle plate rotation difference takes place unstable working condition often do not wait phenomenon; At last do not possess the ability that air-flow is prewhirled, cause energy consumption of electrical machinery to rise.
Summary of the invention
The purpose of this invention is to provide a kind of fan delivery regulating valve, reduce airflow kinetic energy loss, baffle plate flexible movements, stable work in work, possess the air-flow function of prewhirling, solve the problems referred to above of background technique existence.
The objective of the invention is to realize like this:
A kind of fan delivery regulating valve; Comprise rotating handle, baffle plate, damper shaft, valve body, support axle bed, driving handle and transmission shaft; The quantity of baffle plate is a plurality of; All baffle plates are arranged on the inner chamber of valve body, and each baffle plate is fixed on the end of damper shaft, and each damper shaft is arranged on the valve body through two support axle beds after passing valve body; The other end of each damper shaft is fixed on rotating handle middle part, and the two ends of rotating handle are connected with rotating handle on adjacent another damper shaft through transmission shaft respectively, at least one damper shaft driving handle are set.
Each damper shaft all has two bearing axle seats to assist rotation on the valve body, and two bearing axle seats all are arranged on outside the valve body, and outside valve body, have accomplished the location to damper shaft, makes transmission system not take this with regard to narrow and small through-flow space.
Said valve body is a circular valve, and baffle plate is a fan shape baffle, and the plurality of sector baffle combination constitutes circle together, the inner chamber of closed circle valve body.Change flow area through butterfly during use and then reach the purpose of flow control.
The present invention adopts the dual-gripper axle bed to support outside valve body, saves flow area, and the equivalent diameter down-off upper limit is big; Dual-gripper axle bed supporting baffle axle makes the damper shaft fluent movements, and integral working is stable; The rotating handle turning radius is big, and the required torque of rotation damper shaft is less under equal flow total head; The baffle plate sense of rotation confirms according to the blower fan option, and the direction and the impeller that make air-flow air-flow after through valve get into impeller are consistent, make that gas gets into impeller before, have and the air-flow that has been accelerated has the initial velocity of equidirectional.
Good effect of the present invention: make blower fan in transformable range of flow, reach any flow value; The air-flow that has the simultaneously ability of prewhirling; Can cut down the consumption of energy; Reduce gas kinetic energy, static energy loss, energy-saving and emission-reduction, the present invention have that flow area is big, synchronous, the required driving force of fluent movements rotation is little, air-flow is produced the advantage of prewhirling.

Fig. 2 is an embodiment of the invention schematic representation in kind;
Among the figure: rotating handle 1, baffle plate 2, damper shaft 3, valve body 4, support axle bed 5, driving handle 6, transmission shaft 7.
Embodiment
Through embodiment, the present invention is described further below.
A kind of fan delivery regulating valve; Comprise rotating handle 1, baffle plate 2, damper shaft 3, valve body 4, support axle bed 5, driving handle 6 and transmission shaft 7; The quantity of baffle plate is a plurality of; All baffle plates are arranged on the inner chamber of valve body, and each baffle plate is fixed on the end of damper shaft, and each damper shaft is arranged on the valve body through two support axle beds after passing valve body; The other end of each damper shaft is fixed on rotating handle middle part, and the two ends of rotating handle are connected with rotating handle on adjacent another damper shaft through transmission shaft respectively, at least one damper shaft driving handle are set.
Said valve body is a circular valve, and baffle plate is a fan shape baffle, and the plurality of sector baffle combination constitutes circle together, the inner chamber of closed circle valve body.Change flow area through butterfly during use and then reach the purpose of flow control.
The present invention is promoted driving handle 6 and is made damper shaft 3 completion modulating valve baffle plate 2 spinning movements under the assistance of bearing axle seat 5 by transmission shaft 7, rotating handle 1 transmission by external impetus; In the middle of the process of rotation; Valve body 4 inner flow areas change, thereby reach the adjusting purpose to gas flow.
In the middle of the process of regulating action,, the entire exercise of modulating valve is put in place flexibly because the turning radius of driving handle and rotating handle is big; Each damper shaft all has two bearing axle seats to assist rotation on the valve body, the accurate positioning of damper shaft, and outside valve body, accomplished location to damper shaft, make transmission system not take this with regard to narrow and small through-flow space; At the modulating valve assembly process, will consider the option of adapted blower fan, under the prerequisite that does not change blanking, only change installation method and confirm the modulating valve rotation direction, so modulating valve is made simply, save man-hour; The register rotation direction is consistent with the blower fan rotation direction;, air communication makes that its flow direction was consistent with the sense of rotation of impeller when air-flow got into impeller after overregulating valve; So just accomplished prewhirling of air-flow transferred to usefulness; Air-flow has the initial velocity consistent with acceleration direction, and the energy consumption of motor is reduced, and plays the effect of energy-saving and emission-reduction.
