Abstract
The invention discloses an explosion venting valve capable of resetting automatically. The explosion venting valve capable of resetting automatically comprises a valve body; the valve body is provided with a support frame; one end of the support frame is connected with a valve support frame through a bearing; the valve support frame is provided with a valve; a telescopic draw bar is arranged between the valve body and the valve support frame; the lower end of the valve body is provided with a lower hanging lug; the telescopic draw bar is connected with the valve body and the valve support frame through the lower hanging lug; the upper end of the valve support frame and the other end of the support frame are respectively provided with a spring fixing device; and a spring is connected between the two spring fixing devices which are used for hanging the loop valve bodies and are made of carbon steel materials. According to the invention, the valve support frame and the valve body are connected through the telescopic draw bar, and the valve is prevented from popping out to hurt workers because of ultra-high pressure; and the automatic resetting spring can pop the valve automatically to the original place, and gases in pipelines are prevented from leaking. The explosion venting valve capable of resetting automatically provided by the invention has favorable stability and reliability, can reset automatically and quickly through the automatic resetting device after explosion venting so as to prevent leakage.
Description
Technical field
The present invention relates to a kind of valve, relate to specifically the automatically reset explosion-released valve of a kind of energy.
Background technique
Explosion-released valve mainly is during for system overpressure, rupture disk breaks, the moment pressure release, then valve reset is closed explosion-released valve, and the resetting means of the explosion-released valve of existing technology is at valve weight energy device to be installed, by gravity the explosion-released valve of opening is closed, resistance is larger in the process of venting of dust explosion like this, and explosion-released valve weight is large, is inconvenient to move.
Summary of the invention
In order to address the above problem, the invention provides a kind of lightweight and automatically reset explosion-released valve of energy.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of automatically reset explosion-released valve, comprise valve body, be provided with supporting frame at valve body, be connected with the valve supporting frame at an end of supporting frame by bearing, be provided with valve at the valve supporting frame, between valve body and valve supporting frame, be provided with telescopic lever.
Further improvement of the present invention is: be provided with lower hangers in the lower end of valve body, telescopic lever connects valve body and valve supporting frame by lower hangers.
Further improvement of the present invention is: be respectively arranged with the spring fixture in the upper end of valve supporting frame and the other end of supporting frame, be connected with a spring between two spring fixtures.
Further improvement of the present invention is: the spring fixture is link.
Further improvement of the present invention is: valve body for carbon steel material.
The invention has the beneficial effects as follows: be connected by flexible railing between valve supporting frame of the present invention and the valve body, avoid pressure to cross senior general's valve bullet and fall to injure the workman, automatic reset device can bounce back into original position automatically with valve, prevents ducted Leakage Gas.
The present invention has preferably stability and reliability, can automatically reset rapidly by automatic reset device Leakage prevention behind venting of dust explosion.
