Utility model content
The technical issues of the utility model is solved is to provide a kind of quick response safety valve simple in structure, response is fast
Door.
In order to solve the above technical problems, the utility model provides a kind of quick response safety-valve, including valve body, with it is described
The connected mounting bracket of valve body and to be installed on the single-acting being connected with the inputting shaft of the valve body in the mounting bracket pneumatic
Actuator installation limit switches and controls the list of the single-action pneumatic executor action on the single-action pneumatic executor
Electric control solenoid valve；One end of the single-action pneumatic executor is pneumatic end, and the other end of the single-action pneumatic executor is
(the first back-moving spring；One end of the list electric control solenoid valve is automatically controlled end, and the other end of the list electric control solenoid valve is second multiple
Position spring.
Further, the mounting bracket passes through screw lock with the valve body.
Further, the valve body is provided with mounting flange.
Further, the mounting flange is round or rectangular.
The quick response safety-valve of the utility model is divided into two kinds of situations, open type and closed type, and normal work is often
It opens and is powered by the automatically controlled end of single electric control solenoid valve with normally closed control, it is pneumatic that compressed air is sent into the single-acting by control
The pneumatic end of actuator so that the (the first back-moving spring is in compressive state, when encountering abnormal, such as power-off suddenly or disconnected
The of gas or when dying simultaneously, the (the first back-moving spring of the single-action pneumatic executor and single electric control solenoid valve
Two resetting springs reset simultaneously so that and the quick response safety-valve returns to the normally opened or normally off of original state, from
And reduce the impact to waste gas treatment equipment rear end, the protection to rear end is played, has the advantages that response is fast, is improved at exhaust gas
Manage the security performance of equipment.
Description of the drawings
Fig. 1 is the schematic diagram of the quick response safety-valve of the utility model；
In figure label for：Valve body 1, mounting flange 11, mounting bracket 2, single-action pneumatic executor 3, limit switch 4 are single
Electric control solenoid valve 5.
Specific implementation mode
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the accompanying drawings, wherein
Same or similar label indicates same or similar element or element with the same or similar functions from beginning to end.Lead to below
It crosses the embodiment being described with reference to the drawings to be exemplary, it is intended to for explaining the utility model, and should not be understood as to this practicality
Novel limitation.
In the following description, the structure and working method of the utility model in order to clearly demonstrate, will be by all multidirectionals
Word is described, but should by "upper", "lower", "left", "right", "front", "rear", "inner", "outside", " upward ", " downward ",
" to the left ", " to the right ", " forward ", " backward ", " inside ", the Word Understandings such as " outside " are not construed as convenience of term
Word of limitation.
As shown in Figure 1, the utility model provides a kind of quick response safety-valve, including valve body 1, with 1 phase of the valve body
It mounting bracket 2 even and is installed on the single-acting being connected with the inputting shaft of the valve body 1 in the mounting bracket 2 and pneumatically executes
Device 3 installation limit switches 4 and controls the list that the single-action pneumatic executor 3 acts on the single-action pneumatic executor 3
Electric control solenoid valve 5；One end of the single-action pneumatic executor 3 is pneumatic end, the other end of the single-action pneumatic executor 3
For (the first back-moving spring；One end of the list electric control solenoid valve 5 is automatically controlled end, and the other end of the list electric control solenoid valve 5 is the
Two resetting springs.The limit switch 4 is to correspond to rotation according to the movement of the single-action pneumatic executor 3 to export letter
Number；The quick response safety-valve of the utility model is divided into two kinds of situations, open type and closed type, when normal work it is normally opened with it is normal
The control closed is powered by the automatically controlled end of single electric control solenoid valve 5, and compressed air is sent into the single-acting and pneumatically executed by control
The pneumatic end of device 3 so that the (the first back-moving spring is in compressive state, when encountering abnormal, such as powers off or dies suddenly
Or when dying simultaneously, the of the (the first back-moving spring of the single-action pneumatic executor 3 and single electric control solenoid valve 5
Two resetting springs reset simultaneously so that and the quick response safety-valve returns to the normally opened or normally off of original state, from
And reduce the impact to waste gas treatment equipment rear end, the protection to rear end is played, has the advantages that response is fast, is improved at exhaust gas
Manage the security performance of equipment.
The mounting bracket 2 passes through screw lock with the valve body 1.By way of screw lock, locking is convenient and reliable.
The valve body 1 is provided with mounting flange 11, and the mounting flange 11 is round or rectangular.The mounting flange 11
