The inside of every blade is provided with a square shaft, one end of every blade is provided with a cover plate, and a positioning pin fixes the blade, the square shaft and the cover plate together, the square shaft penetrates the side frame; a side short connecting rod is sleeved on the end portion of every square shaft, the inner side of the side short connecting rod of the square shaft is provided with a shaft circlip, and the outer side of the square shaft is sequentially provided with a flat washer, an elastic washer and a nut. The large-air-flow electric combined air valve is reasonable in structural design, smooth in opening and closing, capable of prolonging the service life and applicable to ventilation devices.
Description
Technical field
The utility model relates to ventilation equipment, particularly relates to Wind Volume electric assembling air-valve.
Background technique
In recent years, along with the development of social science and technology, the raising of people's living standard, underground railway traffic is a kind of modernization instrument of city.Wind Volume electric assembling air-valve is requisite equipment in underground railway ventilation and air conditioning system, is the critical piece of realizing various air conditioner patterns and emergency ventilation.When tunnel fan by giving, return air duct, during to public domain, station air conditioner ventilation, at interval, night ventilation and running tunnel, block under work condition state, by Wind Volume electric assembling air-valve throw over switch, control and realize interval ventilation, simultaneously ventilation when compatible station and interval breaking out of fire accident, therefore the structural type of Wind Volume electric assembling air-valve, technical performance quality directly have influence on the normal operation of subway engineering.Substantially roughly the same, the problem of all existence is also substantially similar for the Wind Volume electric assembling wind valve structure that current domestic colleague produces.Reason is 1, blade and square shaft gap too large, because square shaft is to be stuck in the vee gutter of blade bending, then cover blade fixing trim cover plate, recycling fastening piece is fixed square shaft, makes, so when the continuous open and close several of valve body because blade and blade cover plate are all 2mm thin plates, just produced certain interval, therefore just occurred the problems referred to above, and stainless steel square shaft diagonal is wedge angle bad boring again, lower locating stud.2, the square hole of side short connecting rod punching and square shaft are used a period of time wearing and tearing post gap to become large, due to after side short connecting rod square hole is enclosed within on square shaft, cotter pin location by both sides, there is no again hold down gag, so side short connecting rod is on square shaft, rocking up and down, is also to make blade open one of pass not in place reason not in place.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, switch freely, the Wind Volume electric assembling air-valve of long service life.
The utility model is achieved in that Wind Volume electric assembling air-valve, comprise blade, side frame, cover plate, total connecting rod, electric actuator, crank, it is characterized in that: in described blade, be provided with square shaft, one end of blade is provided with cover plate, and locating stud is fixed together blade, square shaft, cover plate; Described square shaft is through side frame, and the end of square shaft cover has side short connecting rod, and square shaft upside short connecting rod inner side is provided with shaft block ring, and side short connecting rod outside is disposed with faced washer, elastic washer, nut.
On square shaft described in the utility model, be provided with elongated slot; Described locating stud is arranged on elongated slot place.
The utility model reasonable in design, switch freely, has extended working life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is I place enlarged view in Fig. 1;
In figure 1, blade, 2, side frame A, 3, side frame B, 4, cover plate, 5, a connecting rod, 6, total connecting rod, 7, electric actuator, 8, crank, 9, faced washer, 10, oil-impregnated bearing, 11, locating stud, 12, square shaft, 13, shaft block ring, 14, elastic washer, 15, nut, 16, side short connecting rod, 17, side long connecting rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, Wind Volume electric assembling air-valve, comprise blade 1, side frame, cover plate 4, total connecting rod 6, electric actuator 7, crank 8, it is characterized in that: in described blade 1, be provided with square shaft 2, one end of blade 1 is provided with cover plate 4, and locating stud 11 is fixed together blade 1, square shaft 2, cover plate 4; Described square shaft 2 is through side frame, and the end of square shaft 2 cover has side short connecting rod 16, and square shaft upside short connecting rod inner side is provided with shaft block ring 13, and side short connecting rod outside is disposed with faced washer 9, elastic washer 14, nut 15.On described square shaft 2, be provided with elongated slot; Described locating stud 11 is arranged on elongated slot place.During concrete enforcement, 20mm is cut to cutoff wheel or cutter blade in square shaft one end long, the groove that 2.5mm is wide, after square shaft and blade and side frame assemble with fastening piece, electricity consumption is drilled in elongated slot active position on square shaft blade, square shaft and blade fixing trim cover plate is bored behind ∮ 3.2 holes simultaneously, after blade, square shaft, cover plate being fixed with locating stud again, make blade and square shaft never becoming loose.With shaft block ring, faced washer, elastic washer and nut, side short connecting rod is fixed on square shaft in addition, gap between square shaft and side short connecting rod is eliminated, never becoming loose.During work
,pass through electric actuator, drive crank, total connecting rod, a connecting rod, square shaft, blade, side short connecting rod, the action of side long connecting rod, by each square shaft, make each blade 4 do opening and closing action, two air-valve switches combining freely, long service life.
