Description
Technical field
It the utility model is related to a kind of valve, more particularly to a kind of semisphere valve with blow device.
Background technology
Under dust, granule medium environment, for steel mill's power-plant flue gas, dust pelletizing system, alumina industry solid particle is situated between
Valve in matter transport system, and the Heisui River of coal chemical industry, buck, Slag-water system uses semisphere valve more.And semisphere valve mainly by
Upper and lower valve rod, valve seat, flap, valve body and executing agency's composition.Upper and lower valve rod is mounted on bearing, the installation of upper valve rod bearing
On valve body, lower valve rod bearing is installed on flap, to reduce the frictional force during valve opening and closing, the keying torque of valve compared with
It is small, while the abrasion of valve sealing face can be reduced and can be squeezed except the attachment on sealing surface, improve service life.But herein
Due to there are solid particle or dust in class operating mode medium, and the upper and lower valve rod of valve with valve body and bearing there are gap, Gu
Body particle, which is particularly easy to enter in gap, makes bearing, stem wear, so that the increase of valve opening and closing torque in turn results in valve rod card
Extremely, cause valve can not normal use, influence to produce.
Utility model content
The purpose of this utility model is to provide a kind of semisphere valve with blow device, to overcome existing for currently available technology
Above-mentioned deficiency, it can remove the solid particle or dust adsorbed on valve rod.
The purpose of this utility model is realized by following structure, it includes：Valve body, sets flap, valve body in valve body
Interior side connecting valve seat, valve seat and flap form sealing pair, and flap connects valve rod, air admission hole, air admission hole are provided with the valve body
Place is equipped with blow device, and blow device is the cylinder which is provided with perforation, and blow device does not have with valve body, blow device and valve rod
There is tie point, blow device is free to rotate with respect to valve rod with respect to valve body, blow device.
The blow device section is I-shaped.
The air inlet position is equipped with corking.
The valve rod of the flap connection is divided into upper valve rod and lower valve rod, and blow device is equipped with upper valve rod and lower valve rod,
And it is provided with air admission hole on the valve body of relevant position.
The perforation is more than one, and is distributed on the circumference of cylinder.
The bottom attachment support of the valve body.
The valve rod is equipped with self-lubricating bearing with the valve body at valve body contact.
The utility model is introduced external high pressure gas in valve chamber by the air admission hole at valve rod, and passes through blow device pair
The solid particle or dust adsorbed on valve rod is purged, and stops that the solid particle in valve body or dust pollute filler upwards,
Avoid the rotation of the accumulation obstruction valve rod of solid particle or dust.Secondly, body base sets support valve body is easily kept
Level, easy to being assembled, transporting, installing and being used by valve.3rd, self-lubricating axis is set at valve rod and valve body contact
Hold, not only reduced the rotating moment of torsion of valve rod, but also easy to pass through cleaning of the gases at high pressure introduced to self-lubricating bearing itself.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the enlarged drawing of part A in Fig. 1.
Embodiment
The embodiment of the utility model includes as shown in Figure 1, Figure 2 and Figure 3：Valve body 1, sets flap 2, valve body 1 in valve body 1
Interior side connecting valve seat 10, valve seat 10 and flap 2 form sealing pair.2 top of flap connection upper valve rod 3 is stated, the bottom of flap 2 connects
Lower valve rod 4 is connect, blow device 5 is equipped with upper valve rod 3 and lower valve rod 4, and air admission hole 6 is provided with the valve body 1 of relevant position,
The top of upper valve rod 3 connection executing agency.The blow device 5 is the cylinder which is provided with perforation 7, and the section of cylinder is I-shaped
Shape, and blow device 5 does not have tie point with valve body 1, blow device 5 and upper lower valve rod, blow device 5 is with respect to valve body 1, purging
The relatively upper lower valve rod of device 5 is free to rotate.Blow device 5 can both play the solid particle or dust stopped in valve body 1
When contacting the filler on top, avoid the pollution to filler from causing the stuck of valve, and can make to be passed through gases at high pressure in valve body
Air flue is formed around upper valve rod or lower valve rod.The air inlet position 6 is equipped with corking 8, will when without the cleaning operation of valve
Air admission hole blocks the sealing for ensureing valve body.Perforation 7 on the blow device 5 is six, and is distributed on the circumference of cylinder.Institute
The bottom welding support 9 of valve body 1 is stated, support 9 is trapezoidal plate.The upper valve rod 3 and the valve body 1 of 1 contact position of valve body are equipped with certainly
Bearing is lubricated, lower valve rod 4 on the valve body 1 of 1 contact position of valve body with also being provided with self-lubricating bearing.
As the improvement of the utility model, perforation on blow device is for 1,2,3,4,5,7 or more
It is more.
The valve of the utility model in cleaning operation, the corking on valve body is turned on respectively first make the inner cavity of valve body with
External world's connection, then connects high-pressure air source on air admission hole, and gases at high pressure are blowed into valve body, and gases at high pressure are filled through purging
The perforation put.When the perforation on blow device is more, gases at high pressure can promote blow device to be rotated around valve rod, so that by valve
The solid particle or dust accumulated on bar are disposed so as to ensure the normal work of valve.And the perforation on sweeping device is less
