Abstract
The utility model discloses a valve limiting apparatus. Compared with the prior art, a rotating shaft and a driving shaft use pair wheel connection, and a timing device is additionally arranged on the driving shaft. Opening and closing limitation is arranged on the timing device. The pair wheel connection uses mutually embedded connection. The valve limiting apparatus of the utility model can avoid the eccentricity of the rotating shaft and the driving shaft well. Thus, effective drive is obtained. The timing device uses a four-stage gear mechanism. Thus, the precision of on-off spacing limitation can be guaranteed, a valve can be effectively started and closed, and production demands are effectively satisfied.
Description
Affiliated technical field
The utility model belongs to ono-rising-stem valve start and stop position limit field.
Background technique
At present, the ono-rising-stem valve that our factory uses is spacing, opens spacing [3] passes spacing [4] by rotatingshaft [1] transmission shaft [2] and forms.More structure adopts to rotate and goes up mantle fiber.Drive the transmission shaft rotation that cogs.Transmission shaft [2] is gone up to install and is hit chi, reaches the purpose of the spacing start and stop motor of switch.This device deficiency is that the start and stop position can not finely guarantee, particularly on long-term valve of stopping transport, the inaccurate motor that causes of gear mesh can not normally move, and influence is produced.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of start and stop motor accurately to satisfy the valve limit stoper of producing.
Valve limit stoper of the present utility model contains rotatingshaft [1] transmission shaft [2] and opens spacing [3] passes spacing [4], and rotatingshaft [1] and transmission shaft [2] adopt wheel is connected, and transmission shaft [2] increases timing device, and switch is installed on the timing device.
Above-mentioned wheel is connected adopted mutual embedded connection, down wheel [6] being welded on rotatingshaft [1] upward is welded on the transmission shaft [2] wheel [7], transmission shaft [2] one ends connect timing device, and switch is spacing to be fixed on the timing device, and timing device shell and valve body are fixed.
The utility model compared with prior art has following effect: adopt and can avoid the rotatingshaft and the inconsiderate heart of transmission shaft effectively to taking turns to connect, accomplished that transmission is effective; Timing device adopts the level Four gear mechanism, guarantee switch spacing accurately, make the valve start and stop effective, satisfy the requirement that stops to send valve for a long time.
The utility model discloses a kind of valve limit stoper, spacing employing mechanical type.Or number is included within the claim of the desired protection of the utility model near switch type.

Fig. 3 is down to the wheel plan view.Fig. 4 goes up the wheel plan view.
1. rotatingshafts, 2. transmission shafts 3. are opened spacing 4. and are closed spacing 5. and hit chi 6. times to taking turns on 7. taking turns 8. timing devices among the figure
Embodiment
During switch valve, rotatingshaft [1] drives transmission shaft [2] rotation in Fig. 2.Timing device on the transmission shaft [8] is when beginning to rotate to the position, and timing device hits chi [5] to cut off switch automatically spacing through wheel is connected, thereby reaches the purpose of start and stop valve.Above-mentioned timing device adopts the level Four gear mechanism, can guarantee switch spacing accurately.
Claims (4)
1, a kind of valve limit stoper, opening spacing [3] by rotatingshaft [1] transmission shaft [2] closes spacing [4] and hits chi [5] and form, it is characterized in that rotatingshaft [1] and transmission shaft [2] adopt connects wheel, and transmission shaft [1] is gone up and increased timing device [8] and open spacing [3] and close spacing [4] and be installed on the timing device.
2, valve limit stoper as claimed in claim 1 is characterized in that wheel is connected the mutual embedded connection of employing.
3, valve limit stoper according to claim 1 is characterized in that out that spacing [3] close spacing [4] and be installed on the timing device [5].
4, limit stoper according to claim 1 is characterized in that timing device shell and valve body fix.
