Abstract
The utility model relates to an air -operated controller detection device specifically is a safe pneumatic valve with hand operations, including setting up the pneumatic valve in the casing, outside the articulating of pneumatic valve has the manual control handle, the top and the below of the free end of manual control handle are equipped with two triggers respectively, the trigger is trigger and lower trigger, going up the trigger and being connected to the closed pilot lamp of pneumatic valve on the casing, the pilot lamp is opened to the pneumatic valve that lower trigger was connected to on the casing, the centre of manual control handle articulates has vertical push -and -pull rod, and the upper end of push -and -pull rod sets up outside the casing, be equipped with the pretension spring between the below of manual control handle and the casing bottom surface. This scheme is compared the action that has the pneumatic valve and is detected with prior art, still have the action compensation, has increased the life and the result of use of pneumatic valve, safe and reliable.
Description
Technical field
The utility model is related to pneumatic control detection means, specifically a kind of safety pneumatic valve with hand gear.
Background technology
At work, pneumatic operated valve is generally used for changing communication direction in gas circuit.And common pneumatic operated valve uses Electronic Control
Conversion, after a long time use, due to the abrasion of rubber sheet gasket in converting member and aging, its sealing effectiveness is worse and worse.And
This sealing effectiveness is slowly to carry out, and pneumatic operated valve air leakage is also what is be stepped up.Therefore for the pass closing and opening of pneumatic operated valve
Whether the detection means that there are currently no in place is opened, meanwhile, when the electronic controller control of pneumatic operated valve is unstable, pneumatic operated valve does not have
There is manual overvide to be controlled temporarily and compensated.
The content of the invention
The purpose of this utility model, is exactly to solve the problems, such as prior art, and devising one kind to have to fill manually
The safety pneumatic valve put, it is rational in infrastructure simple, whether the action of pneumatic operated valve can be detected in place, and with regulation and control work(manually
Can, it is more safe and reliable.
The technical solution of the utility model is：A kind of safety pneumatic valve with hand gear, including be arranged in housing
Pneumatic operated valve, the external articulation of the pneumatic operated valve has manual control handle, above and below the free end of the manual control handle
It is respectively equipped with two triggers；The trigger is upper trigger and lower trigger；The upper trigger is connected on housing
Pneumatic operated valve closes indicator lamp, and lower trigger is connected to the pneumatic operated valve open instruction lamp on housing；The centre of the manual control handle
Vertical pull bar is hinged with, the upper end of pull bar is arranged on outside housing；The lower section of the manual control handle and housing bottom surface it
Between be provided with preloading spring.
The upper end of the pull bar is provided with the termination for being easy to hold.
The pull bar is provided with locking clamp with the junction of housing, the position for locking pull bar.
Steel wire, the other end connection spacing regulation controller of steel wire are also associated with the manual control handle.
It is described to be arranged on the wall of hull outside side away from regulation controller.
The steel wire is turned to by two fixed pulleys.
The beneficial effects of the utility model can be drawn by such scheme：1. pneumatic operated valve is arranged in housing can reduce ring
Infringement of the border to pneumatic operated valve.2. indicator lamp is set on housing, can conveniently display pneumatic operated valve state whether in place, less than
Control can be compensated using manual overvide during position, the use scope and control effect of pneumatic operated valve can be improved.3. hand
Preloading spring is also set up on dynamic control handle to be easy to reset.4. set steel wire connection spacing regulation controller, can be to abrasion after
Pneumatic control components compensate.This programme has the motion detection and motion compensation to pneumatic operated valve, by increasing capacitance it is possible to increase pneumatic operated valve
Service life and using effect, and safe operation, reliability.
As can be seen here, the utility model has substantive distinguishing features and progress compared with prior art, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Wherein, 1 is termination, and 2 is locking clamp, and 3 is pull bar, and 4 is manual control handle, and 5 is pneumatic operated valve, and 6 is preloading spring,
7 is steel wire, and 8 is that spacing adjusts controller, and 9 is housing, and 10 is pneumatic operated valve open instruction lamp, and 11 is that pneumatic operated valve closes indicator lamp.
Specific embodiment：
In order to more fully understand the utility model, implementation method of the present utility model is explained in detail below in conjunction with the accompanying drawings.
Specific embodiment：As shown in figure 1, a kind of safety pneumatic valve with hand gear, including be arranged in housing 9
Pneumatic operated valve 5, the external articulation of the pneumatic operated valve 5 has a manual control handle 4, the top of the free end of the manual control handle 4 and
It is respectively arranged below with two triggers；The trigger is upper trigger and lower trigger；The upper trigger is connected to housing 9
On pneumatic operated valve closure indicator lamp 11, lower trigger is connected to the pneumatic operated valve open instruction lamp 10 on housing；The manual control
The centre of handle 4 is hinged with vertical pull bar 3, and the upper end of pull bar 3 is arranged on outside housing 9, and upper end is provided with the end for being easy to hold
First 1.Pull bar 3 is provided with locking clamp 2 with the junction of housing 9, the position for locking pull bar.The manual control handle 4
Preloading spring 6 is provided between lower section and the bottom surface of housing 9.Steel wire 7, the other end of steel wire 7 are also associated with the manual control handle 4
Steering is carried out by two fixed pulleys be connected to spacing regulation controller 8.It is described to be arranged on outside housing 9 away from regulation controller 8
On the wall of side.
Described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above, this skill
Change, remodeling, addition or replacement that the those of ordinary skill in art field is made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
