Abstract
The utility model relates to a non friction ball face brake valve, comprising a valve body, a valve cover, a bracket, a valve pole and a flashboard. The valve pole is connected with the flashboard which is in the valve body; the flashboard consists of a wedge cone and a ball face valve flap which is connected with the two sides of the wedge cone through a dove tail socket; the upper and the lower parts of the ball face valve flap are respectively provided with a limiting ring and a limiting plate; the valve pole is connected with the cone; the valve pole is horizontally provided with a cross pin whose two ends are provided with rolling wheels; the rolling wheels match the continuous runner and screw guide groove which are arranged on the two sides of the bracket. The utility model overcomes the defects of the current brake valves that when starting and closing, the moving distance of the flashboard is big; the starting and closing time is long; the wearing of the tight surface is fast, having the advantages of high starting and closing speed, no relative friction between the tight surfaces, saving labor when operating, and long service life. According to the measurement, the starting and closing time of the utility model is only one fifth to one tenth of the common brake valve with the same specifications.
Description
Affiliated technical field
The utility model relates to a kind of nothing friction sphere gate valve.
Background technique
Gate valve is present most widely used valve products, is used for the transmission of control media in fields such as oil, chemical industry, metallurgy, electric power, light industry, pharmacy.It has that circulation area is big, flow resistance is little, the advantage of self-locking good anti-vibration, high temperature resistant, high pressure, but since existing gate valve intrinsic structure, also there is following defective simultaneously in its: the displacement distance of flashboard is big when 1, opening and closing, opening and closing time long, inefficiency; 2, big, the quick abrasion of sealing surface of the friction ractor between the sealing pair, working life are short.
Summary of the invention
The displacement distance of flashboard is big when opening and closing in order to overcome gate valve in the prior art, opening and closing time long, the problem of the quick abrasion of sealing surface.The utility model provides a kind of nothing friction sphere gate valve, and this does not have, and the keying speed of friction sphere gate valve is fast, no frictional loss, long service life.
The technological scheme that its technical problem that solves the utility model adopts is: comprise valve body, valve gap, support, valve rod and flashboard, flashboard in valve rod and the valve body is connected, flashboard is made of by the sphere flap that dovetail groove is connected wedge-type cone and wedge-type cone both sides, the upper and lower of sphere flap is respectively equipped with limited ring and position-arresting disk, valve rod is connected with the wedge-type cone, laterally assemble lateral pin on the valve rod, the two ends of lateral pin are provided with roller, and chute and helical guide groove continuous on roller and the support two side match.
The wedge-type cone is protruding sphere at the dovetail groove middle part, becomes point to contact with dovetail groove.
Limited ring and position-arresting disk are fixed on the valve interior wall.
The utility model has the following advantages by above-mentioned specific design: 1, circulation area is big, flow resistance is little, self-locking performance is good, vibration resistance is strong; 2, because sealing pair is made high temperature resistant, high pressure fully by metallic material; 3, keying speed is fast, and opening and closing time has only 1/5th to 1/10th of the common gate valve of same specification; 4, there are not friction relatively, rapid operation, long service life between the sealing pair.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation between support, valve rod and lateral pin;
Fig. 3 is the cross-sectional structural representation of flashboard.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve gap 2, support 3, valve rod 4 and flashboard, flashboard in valve rod 4 and the valve body 1 is connected, flashboard is made of by the sphere flap 7 that dovetail groove 6 is connected wedge-type cone 5 and wedge-type cone 5 both sides, wedge-type cone 5 is protruding sphere at dovetail groove 6 middle parts, contact with 6 one-tenth points of dovetail groove, on sphere flap 7, the below is respectively equipped with limited ring 12 and position-arresting disk 13, limited ring 12 and position-arresting disk 13 are fixed on valve body 1 inwall, valve rod 4 is connected with wedge-type cone 5, horizontal assembling lateral pin 8 on the valve rod 4, the two ends of lateral pin 8 are provided with roller 9, and chute 10 and helical guide groove 11 continuous on roller 9 and support 3 two sides match.During Open valve, valve body 1 at first drives wedge-type cone 5 along chute 10 and rises, by dovetail groove 6 sphere flap 7 is drawn in, make the sealing surface of the sealing surface disengaging valve body 1 of sphere flap 7, lateral pin 8 makes valve rod 4 drive 5 risings of wedge-type cone and revolve and turn 90 degrees, because sphere flap 7 top restraining position ring blocks 12 block under the restriction of helical guide groove 11 then, can only can not rise with 5 rotations of wedge-type cone, at this moment valve open.Descend when valve rod 4 counterrotatings drive wedge-type cone 5,, can not descend with wedge-type cone 5 because sphere flap 7 bottoms have position-arresting disk 13 to hold, can only relatively move along dovetail groove 6, strut to both sides in valve body 1 runner direction, sealing surface is fitted, realize valve closing.
Claims (3)
1, a kind of nothing friction sphere gate valve, comprise valve body, valve gap, support, valve rod and flashboard, flashboard in valve rod and the valve body is connected, it is characterized in that flashboard is made of by the sphere flap (7) that dovetail groove (6) is connected wedge-type cone (5) and wedge-type cone (5) both sides, on the sphere flap (7), the below is respectively equipped with limited ring (12) and position-arresting disk (13), valve rod (4) is connected with wedge-type cone (5), valve rod (4) is gone up laterally assembling lateral pin (8), the two ends of lateral pin (8) are provided with roller (9), and chute (10) and helical guide groove (11) continuous on roller (9) and support (3) two side match.
