Abstract
The utility model discloses a kind of manual eccentric half-ball valves of band limit, comprising: valve body, valve body is connected with terminal pad, valve chamber is set in valve body, valve seat and flap are equipped in valve chamber, flap connects valve rod, position-arresting disk is connected on the valve rod, position-arresting disk is equipped with limit hole, caging bolt passes through limit hole, caging bolt one end connects stop nut, and the other end of caging bolt is connected in terminal pad, can be fixed on the position when can lock valve rod to make flap rotate to any position between starting and ending position.
Description
Technical field
The utility model relates to the manual eccentric half-ball valves that a kind of valve more particularly to a kind of band limit.
Background technique
Existing manual eccentric half-ball valve is often set on the handle connecting with valve rod to limit flap switch over travel
There is limit baffle, by the limit baffle on handle and the male cooperation on valve body, the limit of flap stroke is realized, to guarantee
Valve effectively shuts off.And existing this manual eccentric half-ball valve, limit is only in its work of the starting and ending position of stroke
With, and handle is not locked between starting and ending position.The rate-of flow and when larger pressure in valve body, in valve body
The position of flap be easy to happen variation, to cause the variation of rate-of flow, generally require constantly to monitor adjustment.Secondly,
For the malfunction for preventing valve, it is sometimes desirable to unload lower handle, but existing valve will affect the opening and closing of flap when removing handle
Position, and do not allow the installation site for easily causing handle to change when handle is turned round and stretched out the hand in installation.
Utility model content
The purpose of the utility model is to provide a kind of manual eccentric half-ball valves of band limit, to overcome currently available technology to deposit
Above-mentioned deficiency, can lock valve rod to so that flap is rotated to any position between starting and ending position when can be in the position
It sets fixed.
The purpose of this utility model is realized by following structure comprising: valve body, valve body are connected with terminal pad,
It sets valve chamber in valve body, valve seat and flap is equipped in valve chamber, flap connects valve rod, position-arresting disk is connected on the valve rod, on position-arresting disk
Equipped with limit hole, caging bolt passes through limit hole, and caging bolt one end connects stop nut, and the other end of caging bolt is connected to
In terminal pad.
The valve stem end is detachably connected handle.
The valve rod is upper valve rod and lower valve rod, and upper valve rod and lower valve rod are separately connected the both ends of flap, upper valve rod connection
Position-arresting disk.
Circlip for shaft is equipped between the handle and position-arresting disk.
It is equipped with bearing between the upper valve rod and valve body, bearing also is provided between lower valve rod and flap.
The caging bolt is located in stop sleeve.
The stop nut is dish shape nut.
The utility model is cooperated by the position-arresting disk, stop nut and caging bolt connecting with valve rod, to control valve rod
Turned position, and then control the flap that connect with valve rod, the position for rotating flap in valve body locks, and facilitates stream
The control of amount, the position of flap changes when not appearing in valve vibration.Secondly, the utility model position-arresting disk, limit spiral shell
Female and caging bolt is locking device, separately positioned with handle, and disassembly and installation handle all will not influence the intracorporal flap of valve
Position.Third, the utility model will not occur because of handle cisco unity malfunction such as: handle damage, and caused by can not lock
The case where flap position.4th, the utility model protects the bolt in it by stop sleeve, places locking device by outer
Boundary's environmental corrosion causes locking device to use difficult situation.
Detailed description of the invention
Fig. 1 is that figure is cutd open in the structural representation of the utility model, and Fig. 2 is the top view of the utility model.
Specific embodiment
The embodiments of the present invention as depicted in figs. 1 and 2 includes: valve body 1, and valve body 1 is connected with terminal pad 2, valve body 1
Valve chamber is inside set, valve seat 3 and flap 4 are equipped in valve chamber, valve rod is upper valve rod 5 and lower valve rod 6, and upper valve rod 5 and lower valve rod 6 connect respectively
The both ends of flap 4 are connect, upper valve rod 5 connects position-arresting disk 7, and position-arresting disk 7 is equipped with arc-shaped limit hole 8, and caging bolt 9 passes through limit
Position hole 8,9 one end of caging bolt connect stop nut 10, and the other end of caging bolt 9 is connected in terminal pad 2.Upper valve rod 5
End is detachably connected handle 11 by bolt.Circlip for shaft 12 is equipped between handle 11 and position-arresting disk 7.Upper valve rod 5 and valve
It is equipped with bearing 14 between body 1, also is provided with bearing between lower valve rod 6 and flap 4.The caging bolt 9 is located in stop sleeve 13, limit
Nut 10 is dish shape nut.
To the above description of disclosed embodiment, those skilled in the art is made to can be realized or use this reality
With novel, a variety of modifications to present embodiment are it will be apparent that as defined herein one to those skilled in the art
As principle can realize in other embodiments without departing from the spirit or scope of the present utility model.Therefore, all
Be with the same or similar technical solution of present embodiment, all fall in the protection scope of the utility model.
