Abstract
The utility model relates to a flat-suction-preventive mechanism of a suction-type baghouse. The flat-suction-preventive mechanism of the suction-type baghouse at least comprises a valve plate, a valve rod, a valve body, a pressure spring and a lock nut. The flat-suction-preventive mechanism of the suction-type baghouse is characterized in that the valve body is fixed on the pipe wall of a system pipeline, the valve plate is sleeved on the position of a valve opening, above the valve body, of the system pipeline, the valve rod is fixed on the bottom of the valve plate, the pressure spring is sleeved outside the valve rod, and the pressure spring is connected between a spring seat at the bottom end of the valve rod, and the valve body in a pressing mode. The flat-suction-preventive mechanism of the suction-type baghouse protects a baghouse system device from being sucked to be flat, and enables the differential pressure of the interior and the exterior of a system to restore to be of a safe value.
Description
Technical field
The utility model relates to deduster field, particularly a kind of flat mechanism of anti-suction that is applicable to Bag House Filter With Negative Pressure.
Background technique
The Bag House Filter With Negative Pressure of environmental protection industry (epi) use at present all prevents inhaling flat mechanism, therefore, in newly-built equipment trial run or equipment use, usually have because accidental cause causes the deduster body to be inhaled flat accident by induced draught fan and occur, not only damaged the deduster integral device, and can bring very burden to activity in production, bring about great losses to the owner.
Summary of the invention
It is flat by suction that the purpose of this utility model is to provide a kind of protection duster system equipment, and the system inside and outside differential pressure of making returns to the flat mechanism of anti-suction of the Bag House Filter With Negative Pressure of security value (s).
The technological scheme that its technical problem that solves the utility model adopts is: the flat mechanism of anti-suction of Bag House Filter With Negative Pressure, which comprises at least valve plate, valve rod, valve body, holddown spring, lock nut, it is characterized in that: valve body is fixed on the tube wall of system pipeline, the system pipeline valve port position of valve body top is socketed with valve plate, the valve plate bottom is fixed with valve rod, valve rod is socketed with holddown spring outward, and Compress Spring is crimped between the spring seat and valve body of valve rod bottom.
Described valve body comprises inner core, urceolus, support plate, cylindrical central sleeve, the tube wall lower opening place of urceolus and system pipeline is fixedly connected with, the urceolus inboard is fixed with a circle inner core, the circular groove of valve plate by the outer is socketed in the inner core top, cylindrical central sleeve is fixedly connected on the middle home position of inner core by support plate, valve stem slides is connected in cylindrical central sleeve, and the bottom of cylindrical central sleeve is connected with the Compress Spring top.
Stud with seal ring in the circular groove of described valve plate, seal ring is rubber seal.
On the sidewall of described cylindrical central sleeve, grease nipple is arranged.
The beneficial effects of the utility model are: when negative pressure value in system pipeline when setting numerical value; the inside and outside both sides of valve plate pressure reduction increases; under the effect of outside atmospheric pressure; valve plate is moved in system pipeline together with valve rod; valve plate and valve body lose annexation; open valve port, a large amount of ambient airs escape into and make that system's external and internal pressure is poor to be reduced, and protective system equipment is not inhaled flat.Valve plate has compressed Compress Spring in the time of mobile in the system pipeline together with valve rod, and after system's inside and outside differential pressure returned to security value (s), the Compress Spring resilience made the valve plate return, again the valve port of shutoff valve body.
Description of drawings
Below in conjunction with embodiment's accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation that the utility model is assemblied in the system pipeline place;
Fig. 2 is structural representation of the present utility model;
In figure: 1, system pipeline; 2, valve plate; 3, valve rod; 4, valve body; 5, holddown spring; 6, lock nut; 7, seal ring; 8, support plate; 9, grease nipple; 10, cylindrical central sleeve; 11, spring seat; 12, inner core; 13, urceolus.
Embodiment
Embodiment 1
as shown in Figure 1, the anti-suction flat mechanism of this Bag House Filter With Negative Pressure is assemblied in the tube wall place of system pipeline 1, by valve plate 2, valve rod 3, valve body 4, holddown spring 5, lock nut 6 forms, valve body 4 is fixed on the tube wall of system pipeline 1, there is valve plate 2 the valve port position that system pipeline 1 is closed in valve body 4 tops, valve plate 2 bottoms are fixed with valve rod 3, the outer holddown spring 5 that is socketed with of valve rod 3, there is spring seat 11 lock nut 6 tops that are fixed on valve rod 3 bottoms, Compress Spring 5 bottoms are socketed on spring seat 11, Compress Spring 5 tops contact with valve body 4, Compress Spring 5 is crimped between spring seat 11 and valve body 4.
When negative pressure value in system pipeline 1 when setting numerical value; valve plate 2 inside and outside both sides pressure reduction increase; under the effect of outside atmospheric pressure; make valve plate 2 together with valve rod 3 to the interior movement of system pipeline 1; valve plate 2 loses annexation with valve body 4; open valve port, a large amount of ambient airs escape into and make that system's external and internal pressure is poor to be reduced, and protective system equipment is not inhaled flat.Valve plate 2 has compressed Compress Spring 5 together with valve rod 3 to system pipeline 1 interior movement the time, and after system's inside and outside differential pressure returned to security value (s), Compress Spring 5 resiliences made valve plate 2 returns, again the valve port of shutoff valve body 4.
Due to the effect of valve plate 2 gravity and Compress Spring 5, valve plate 2 tightly is not pressed on inner core 12 when mechanism does not work, the seal ring 7 of valve plate 2 and inner core 12 contact positions has been guaranteed the sealing of link position.
The parts that the present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
