Abstract
The utility model relates to a submerged type pulse valve with a novel sealing member, which is connected with an air bag or an air-distributing box. The pulse valve comprises a pilot portion, a first valve cover, a second valve cover and a valve body which are sequentially connected. Springs are arranged in both the first valve cover and the second valve cover, a first diaphragm assembly is arranged at the connecting position of the first valve cover and the second valve cover, and a second diaphragm assembly is arranged at the connecting position of the second valve cover and the valve body. An annular fixed groove is arranged at the connecting position of the valve body and the air bag or the air-distributing box, and a sealing member is arranged in the annular fixed groove. The sealing member comprises an annular body and an extending piece integrally connected on the outer side of the annular body. A hole is arranged on the extending piece, an annular strip is arranged on the annular body and integrally connected with the annular body, and the annular strip is arranged in the annular fixed groove in clamping mode. Compared with the prior art, the submerged type pulse valve with the novel sealing member has the advantages of enabling sealing performance of the valve body and the air bag or the air-distributing box to be better and the like.
Description
Technical field
The utility model relates to a kind of sentinel valve, especially relates to a kind of submerged sentinel valve with new type sealing element.
Background technique
The submerged sentinel valve of band new type sealing element is a kind of of sentinel valve; In main application and the sack cleaner; It utilizes variation of gas pressure to make pressurized gas in the gas bag (branch gas tank) jet in the air chamber of sack cleaner and make attached to the solid dust on the filtering material to break away from, be the crucial accessory of sack cleaner.Use treating flour dust and assembling sphere widely with every profession and trade.
Because the submerged sentinel valve of band new type sealing element is to be connected with gas bag (branch gas tank), and is full of pressurized air in the gas bag (branch gas tank), so there is sealing problem.The submerged sentinel valve (like Fig. 1) of the band new type sealing element that convention is used is made up of guide's part, first valve gap, second valve gap, spring, primary diaphragm assembly, secondary diaphragm assembly, valve body, Sealing etc.Guide's part can directly be connected on first valve gap through screw; Also can be connected with first valve gap through tracheae; First valve gap is connected spring, primary diaphragm assembly and second valve gap through screw; Second valve gap makes spring, secondary diaphragm assembly be connected with valve body through screw, and sentinel valve is connected with gas bag (branch gas tank) through bolt, has Sealing to be used to guarantee the sealability between sentinel valve and the gas bag (branch gas tank) on the valve body 7.
Sealing adopts the O RunddichtringO usually, utilizes bolt force that the O RunddichtringO is deformed to produce seal pressure to guarantee sealing.If but gas bag is the circle gas bag, need flange to be connected because the flange of gas bag (branch gas tank) need weld very easily distortion with sentinel valve, cause sealing surface uneven, very easily produce the leakage that seal failure causes pressurized gas; If the gas bag side of being gas bag need be used for being connected with sentinel valve by the tapping through hole on the gas bag plane, be to stop the tapped hole place to be leaked by the structure O RunddichtringO of being accustomed to.
The model utility content
The purpose of the utility model is exactly to provide a kind of sealability that makes valve body and gas bag or branch gas tank better with the submerged sentinel valve of new type sealing element in order to overcome the defective that above-mentioned existing technology exists.
The purpose of the utility model can realize through following technological scheme: a kind of submerged sentinel valve with new type sealing element; Be connected with gas bag or branch gas tank, described sentinel valve comprises guide's part, first valve gap, second valve gap and the valve body that connects successively, is equipped with spring in described first valve gap, second valve gap; The joint of first valve gap and second valve gap is provided with the primary diaphragm assembly; The joint of second valve gap and valve body is provided with the secondary diaphragm assembly, and annular fixed groove is offered in the joint of described valve body and gas bag or branch gas tank, is provided with Sealing in the annular fixed groove; It is characterized in that; The sealing part comprises that ring body and integral type are connected the extension piece in the ring body outside, and perforate on the described extension piece is provided with annular bar above the described ring body; This annular bar is connected with the ring body integral type, and described annular bar is fastened in the annular fixed groove.
That offers on the number of described extension piece and the valve body is used for gas bag or divides the number of the bolt hole that gas tank is connected identical.
Compared with prior art, the utlity model has following advantage:
1, substituted original O RunddichtringO with novel Sealing, Sealing produces seal pressure through valve body with the compression that is connected on gas bag or branch gas tank plane, thereby has guaranteed the sealability between sentinel valve and the gas bag (branch gas tank) more.
2, the Sealing that the utility model adopted is the structure that has O RunddichtringO sealing principle and flat pad sealing principle simultaneously, has guaranteed the sealability between sentinel valve and the gas bag (branch gas tank) more thereby can remedy the sealing surface the effect uneven and side's of sealing gas bag tapped through hole source of leaks that the welding of round gas bag flange causes.
