Description
One, technical field
The utility model relates to butterfly valve, particularly a kind of big latus rectum butterfly valve apparatus.
Two, background technique
At present, the on-the-spot big latus rectum automatic butterfly valve that uses is the keying that realizes valve by the driven by motor reducing gear, but it also exists following shortcoming or deficiency simultaneously: 1. complex structure, and the manufacture cost height, actuation time is long, generally greater than 7s.Time has been covered with enough not the needs in the combustion gas utilized device.Because this valve is special-purpose a kind of butterfly valve in the combustion gas utilization, requires this valve events speed to be no more than 2s, and act frequently; 2. long-term energising is easily generated heat, energy consumption is big.
Three, summary of the invention
The purpose of this utility model provides a kind of improved big latus rectum butterfly valve apparatus, adopt the motion of solenoid directional control valve control cylinder, the keying of the motion control butterfly valve of cylinder is avoided effectively or is overcome shortcoming or the deficiency that exists in the above-mentioned prior art, improves actuation time effectively.
Big latus rectum butterfly valve apparatus described in the utility model, comprise compressor, solenoid directional control valve, throttle valve, cylinder and butterfly valve, described butterfly valve comprises valve body, on installing on the valve body, following curtain shaft and butterfly door, bearing is installed on the last curtain shaft in turn, bearing cap, pad and gland, last curtain shaft top is equipped with sensor and support thereof on one side, another side is equipped with crank, be connected with joint shaft bearing extension bar and cylinder on the crank in turn, the other end of cylinder is installed on the cylinder support, the cylinder support is installed on the valve body top, described solenoid directional control valve is connected with cylinder by one-way throttle valve, and cylinder is connected with butterfly valve.The motion of solenoid directional control valve control cylinder, the keying of the motion control butterfly valve of cylinder.
Wherein, described valve body top is equipped with anti-explosion terminal box near last curtain shaft position.On the curtain shaft " O " shape Sealing is installed under described.Described joint shaft bearing extension bar is connected by joint pin with crank.Described upward curtain shaft and its bearing top are packing seal.
The utility model compared with prior art has following advantage:
1, adopt pneumatic control, actuation time is fast, from the standard-sized sheet to the complete shut-down or complete and be less than 2s to time of standard-sized sheet.
2, valve adopts nonmetallic material, and terminal box adopts anti-explosion terminal box, safety anti-explosive superior performance.
3, axially adopt double seal, axle adopts the sealing of " O " shape Sealing with the valve body cooperation place, and packing seal is adopted in the end, good sealing effect, and sealing is reliable.
4, all surfaces that contacts with gas all adopt chemical treatment method to handle, thereby antiseptic property is good.
Four, description of drawings
Fig. 1 is a kind of structural representation of the present utility model,
Fig. 2 is for to look schematic representation by a structure left side shown in Figure 1,
Fig. 3 is by structure schematic top plan view shown in Figure 1,
Fig. 4 is for pressing structure control operating principle schematic flow sheet shown in Figure 1.
Five, embodiment
Consult Fig. 1-Fig. 4, a kind of big latus rectum butterfly valve apparatus, comprise compressor, solenoid directional control valve, throttle valve, cylinder and butterfly valve, butterfly valve comprises valve body 1, on installing on the valve body, following curtain shaft 12,3 and butterfly door 4, on the last curtain shaft 12 bearing 5 is installed in turn, bearing cap 6, pad 7 and gland 9, last curtain shaft top is equipped with sensor 11 and support 10 thereof on one side, another side is equipped with crank 13, be connected with joint shaft bearing extension bar 15 and cylinder 16 on the crank in turn, the other end of cylinder is installed on the cylinder support 17, the cylinder support is installed on valve body 1 top, and solenoid directional control valve 20 is connected with cylinder 16 by one-way throttle valve 21, and cylinder is connected with butterfly valve.The motion of solenoid directional control valve control cylinder, the keying of the motion control butterfly valve of cylinder.
Valve body 1 top is equipped with anti-explosion terminal box 18 near last curtain shaft 12 positions." O " shape Sealing 2 is installed on the following curtain shaft 3.Joint shaft bearing extension bar 15 is connected by joint pin 14 with crank 13.Last curtain shaft 12 is packing seal 8 with its bearing top.
During operation, air compressor 19, air pressure 0.8MPa can provide tolerance 〉=0.3m/min.Compressor carries gas holder.The pressurized air of gas holder carries out using for system after the voltage stabilizing through the source of the gas controlling device of compressor 19.During the energising of the lower coil of solenoid directional control valve 20, source of the gas enters the cavity of resorption of cylinder 16 by solenoid directional control valve 20, the up butterfly valve 23 of opening of cylinder piston, and the air on piston top is through one-way throttle valve 21 and solenoid directional control valve 20 emptying; When the upper coil of the lower coil of solenoid directional control valve 20 and solenoid directional control valve 20 was switched on simultaneously, source of the gas entered the piston top of cylinder 16 by selector valve 20, one-way throttle valve 21, and descent of piston is closed butterfly valve 23, and the air of piston bottom is through selector valve 20 emptyings.The effect of one-way throttle valve 21 is the speed of regulating the piston motion of cylinder 16.(as Fig. 4)
