Abstract
A blowing valve for coal powder used in transportation system of steelmaking and iron making comprises a valve body, a valve cap, a flexible seal, a wedge shape positioning ring, a shield ring for the shaft, a rotation arm, a shaft, a pin, a adjusting bolt, a spring and a manhole cover plate. The flexible seal is arranged in the valve cap. The wedge shape positioning ring pressing the flexible seal is arranged in the hole of the valve body. The shield ring for the shaft is set in the slot of the wedge shape positioning ring with one end contacting one surface of the valve body. The valve cap is connected with the rotation arm 9 through the pin. The rotation arm is connected with the shaft by a spine coupling. Comparing with the coal powder transportation system for steel making and iron making where a globe valve is used , The utility model possesses advantages of long service life, resistance to damage, tight locking and no leakage, because of tight sealing of connection between the rigid valve cap and the flexible seal.
Description
Affiliated technical field
The utility model relates to a kind of valve, the breeze blowing valve of using in the coal powder conveying system when particularly relating to a kind of steel-making, ironmaking.
Background technology
The valve of using in the coal powder conveying system when steel-making, ironmaking all is to use ball valve at present, and its weak point is to use the life-span short, bad easily, is not closed completely in the time of should closing.
Summary of the invention:
The purpose of this utility model is to overcome in present steel-making, when ironmaking coal powder conveying system with the weak point of ball valve, provide a kind of make the life-span long, do not allow perishable, close tight breeze blowing valve.
The purpose of this utility model is achieved through the following technical solutions, and the breeze blowing valve is made up of valve body 1, valve gap 3, flexible gasket 2, wedge shape nest 5, shaft block ring 4, pivoted arm 9, rotating shaft 10, pin 6, set screw 7, spring 8 and manhole plate 11.Flexible gasket 2 is contained on the valve body 1, wedge shape nest 5 is pressed in the hole that is contained on the flexible gasket 2 on the valve body 1, shaft block ring 4 is inlaid in the groove on the wedge shape nest 5, one plane contact of one end and valve body 1, valve gap 3 links by pin 6 and pivoted arm 9, use splined between pivoted arm 9 and the rotating shaft 10, hole and valve gap 3 that set screw 7 was led on spring 8 and the pivoted arm 9 link, and people's orifice plate 11 covers on valve body 1.Flexible gasket 2 is wedge shape and is inlaid in the wedge shape hole slot on the valve body 1.
The utility model is compared with the ball valve that all is to use in the coal powder conveying system of steel-making, ironmaking at present, have because of the valve gap 3 that uses rigidity and flexible seal gasket 2 pinch-off seal that contacts, so long service life, do not allow perishable, when closing very tight, can not leak.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, among the figure direction shown in the arrow be pulverized coal flow to
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawing: 1---valve body; 2---flexible gasket; 3---valve gap; 4---shaft block ring; 5---the wedge shape nest; 6---pin; 7---set screw; 8---spring; 9---pivoted arm; 10---rotating shaft; 11---manhole plate.Valve body 1, valve gap 3, pivoted arm 9 can be used steel casting, also available ironcasting when implementing.Flexible gasket can be used the rubber manufacturing, and also available other flexible sealing material is made.Rotating shaft 10 links with propulsion source (as electrical motor, hydrostatic drive axle etc.) during use, rotating shaft 10 left-hand revolutions when needs are opened, and rotating shaft 10 clockwise rotates when closing, and is opened to standard-sized sheet and is closed to when fastening rotating shaft 10 to stop the rotation.The effect of set screw 7 be by adjusting make valve gap 3 around and seal gasket 2 when fastening its to compress degree identical, thereby realization is closed very sternly when closing, no leak.
