The spring can be directly connected with the case and the sensing panel, or connected with the case and the sensing panel in an internally threaded manner, the length of the spring can be adjusted, or springs with different specifications can be replaced under different explosion venting requirements so as to realize adjustability of explosion venting peak values at any time, and the pressure sensing device can automatically send out alarm within a designed pressure peak value range, and automatically open the explosion venting door and window to realize decompression and pressure discharge.
Description
Technical field
The utility model relates to a kind of venting of dust explosion door and window pressure sensitive device, belongs to induction installation and door and window fields.
Background technology
Along with developing rapidly of industrial and mining enterprises, according to national security production supervision management board the safety in production machine public safety safeguard of national every profession and trade is had higher requirement, in conjunction with military enterprise, the incident explosion accident of petroleum chemical enterprise, antiknock door and window, venting of dust explosion door and window are had higher requirement.Automatically venting of dust explosion is a kind of practicable safety measure, is optimal selection.
At present, produce the enterprise of venting of dust explosion door and window in the industry, substantially all adopt the method for venting of dust explosion bolt, this method can only could rupture when pressure peak reaches maximum critical limit, has certain potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes existing venting of dust explosion door and window induction installation, and a kind of adjustable, safe induction installation is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The pressure sensitive device of venting of dust explosion door and window, cabinet is connected with tablet by horizontal guide rail, spring; One end of described horizontal guide rail is fixed in the cabinet, and it is outer and be slidingly connected with the tablet of cabinet side that the other end extends to cabinet; Described spring one end is fixed in the cabinet, and the other end extends to outside the cabinet and with tablet and is connected; Described tablet lateral surface is the spill arc surface; The tablet medial surface is provided with the contact that is projected on cabinet, and the adjacent position of contactor end is provided with switch, and switch is connected with control system.Spring can directly be connected with cabinet, tablet, or connects by the interior screw rod of establishing, under different ventings of dust explosion requires, and the model of the length of adjustable springs or replacing spring, thus realize that the venting of dust explosion peak value is adjustable at any time.Guide rail is the high accuracy guide rail, thereby guarantees the venting of dust explosion accuracy.
Further, described tablet medial surface is provided with rubber pad, and tablet is under pressure near cabinet, both active forces when colliding of rubber pad available buffer.
Switch is mechanical switch or contact-making switch, when tablet drive contact is mobile to the inside, and contact of switch machinery or induction contact contact, thereby start-up control system.
Be provided with perpendicular to the tablet medial surface and be slightly larger than backboard cabinet, that coat the cabinet end, backboard can make things convenient for the maintenance of cabinet inside, and easy accessibility, and dustproof and waterproof guarantee the accuracy of system.
Action principle is: when room pressure increases, tablet is because of inside and outside side view difference, the pressure that outside cambered surface is subjected to is bigger, therefore tablet moves under pressure to the inside, thereby drive the contact trigger switch, control system is opened, and can open alarm lamp and electromagnetic lock is cut off the power supply automatically, thereby open the venting of dust explosion door and window, reach the venting of dust explosion purpose; After the pressure after the reduction of discharging met safety standard, tablet can rebound under the effect of springback power automatically, sets back.
The induction installation of this design can arbitrarily be adjusted the venting of dust explosion peak value according to the requirement of venting of dust explosion peak value, the intuitively effectively reduction of discharging of control room internal pressure, and can in design pressure peak value scope, report to the police automatically, open the venting of dust explosion door and window automatically, realize the decompression discharging.Alarm lamp can be installed in Control Room, or interlock control electromagnetic lock.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of manual, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model induction installation;
Fig. 2 is the spring connection diagram of the induction installation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Embodiment 1
As Fig. 1-shown in Figure 2, the pressure sensitive device of venting of dust explosion door and window, cabinet 1 is connected with tablet 10 by horizontal guide rail 2, spring 11; One end of high-precision horizontal guide rail 2 is fixed in the cabinet 1, and it is outer and be slidingly connected with the tablet 10 of cabinet 1 side that the other end extends to cabinet; Spring 11 directly is connected with cabinet 1, tablet 10, and the one end is fixed in the cabinet, and the other end extends to outside the cabinet and with tablet 10 and is connected, and tablet 10 lateral surfaces are the spill arc surface; Tablet 10 medial surfaces are provided with the contact 6 that is projected on cabinet 1, and the adjacent position of contact 6 ends is provided with switch 5, and switch 5 is connected with control system, and control system comprises alarm lamp 9 and electromagnetic lock.Under different ventings of dust explosion requires, the model of the length of adjustable springs 11 or replacing spring 11, thus realize that the venting of dust explosion peak value is adjustable at any time.
Action principle is: when room pressure increases, tablet is because of inside and outside side view difference, the pressure that outside cambered surface is subjected to is bigger, therefore tablet moves under pressure to the inside, thereby drive the contact trigger switch, control system is opened, and can open alarm lamp and electromagnetic lock is cut off the power supply automatically, thereby open the venting of dust explosion door and window, reach the venting of dust explosion purpose; After the pressure after the reduction of discharging met safety standard, tablet can rebound under the effect of springback power automatically, sets back.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
