Abstract
The invention relates to the technical field of safety valves, in particular to a spring type emergency cut-off valve. The spring type emergency cut-off valve comprises a valve body, a lower valve deck and an upper valve deck. A top cover is connected to the upper portion of the upper valve deck. A valve rod is arranged in the valve body. The portion, close to the lower valve deck, of the valve rod is sleeved with a lower spring. One end of the lower spring is fixed to the lower valve deck, and the other end of the lower spring is connected with a lower valve plate. The portion, close to the upper valve deck, of the valve rod is sleeved with an upper spring. One end of the upper spring is fixed to the upper valve deck, and the other end of the upper spring is connected with an upper valve plate. A pilot type connecting rod is arranged inside the top cover. An electromagnetic is arranged on the upper valve deck. The spring type emergency cut-off valve is reasonable in design and quite convenient to install and maintain, under the mutual cooperation of the upper spring and the lower spring as well as the mutual cooperation of the upper valve plate and the lower valve plate, the spring type emergency cut-off valve can be closed rapidly once power is off, and meanwhile the sealing performance is good.
Description
Technical field
The present invention relates to Safety valve technical field, especially a kind ofly to close fast and the spring type Emergeny Cutoff Valves of good seal performance.
Background technique
Emergeny Cutoff Valves is emergency cut-off valve or open valve after running into emergency case power-off, its working principle is: the wind spring of electric spring Emergeny Cutoff Valves after powered up inside motor powered final controlling element, torque force is conducted on wind spring, the torque force that wind spring release the inside stores when power-off, band movable valve is closed rapidly or opens.Traditional cut-off valve complex structure, installs and maintenance comparatively complexity, close rapid, and sealability is bad, easily reveals.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, closes rapidly and the spring type Emergeny Cutoff Valves of good seal performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spring type Emergeny Cutoff Valves, and the bonnet comprising valve body, be installed on the bottom flange below valve body and be installed on above valve body, is connected with top cover above bonnet; Described valve body is built-in with valve rod, and valve rod is arranged with lower spring near bottom flange place, and lower spring one end is fixed on bottom flange, and the lower spring the other end is connected with lower valve plate; Described valve rod is arranged with upper spring near bonnet place, and upper spring one end is fixed on bonnet, and the upper spring the other end is connected with valve plate; Described top cover is built-in with the leading type connecting rod be connected with valve rod, and leading type connecting rod is arranged with cylinder body, piston, axle sleeve and seal ring from top to bottom successively; Described bonnet is provided with electromagnet.
Further, described valve body is provided with import export.
Further, described valve body is provided with flange in inlet and outlet, and flange is provided with the mounting hole be connected with other pipelines.
Further, connected by clamping bolt between described bonnet and valve body, connected by clamping bolt between bottom flange and valve body.
Further, described seal ring is positioned at the position that bonnet and top cover contact.
The invention has the beneficial effects as follows: the present invention is reasonable in design, install and keep in repair very convenient, upper spring and lower spring, on valve plate and lower valve plate cooperatively interacting under, once power-off, close rapidly, simultaneously good seal performance.
