Abstract
The utility model relates to a novel submerged pulse valve. The pulse valve comprises a guiding part, a first valve cover, a second valve cover, a first spring, a second spring, a first membrane component, a second membrane component, a valve body and a sealing element, wherein the guiding structure is connected with the valve covers, the first valve cover is connected with the second valve cover,the first spring and the first membrane component are arranged between the first valve cover and the second valve cover, the first spring is pressed above the first membrane component, the second valve cover is connected with the valve body, the second spring and the second membrane component are arranged between the second valve cover and the valve body, the second spring is pressed above the second membrane component, the sealing element is arranged on the valve body, a semi-sealed cavity is arranged on the sealing element, a passage is arranged on the valve body, and the passage is communicated with the cavity of the sealing element and the inside of the valve body. The novel sealing element for the novel submerged pulse valve replaces original O-shaped packing washers, thereby guaranteeing the sealing performance between the pulse valve and air bags.
Description
Technical field
The utility model relates to a kind of sentinel valve, relates in particular to novel submerged sentinel valve.
Background technique
The submerged sentinel valve 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 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 of custom usefulness is made up of guide's part 1, first valve gap 2, second valve body 5, first spring 3, second spring 10, primary diaphragm assembly 4, secondary diaphragm assembly 6, valve body 7, Sealing 8 etc. as shown in Figure 1.Guide's part 1 can directly be connected on first valve gap 2 by screw, also can be connected with first valve gap 2 by tracheae, first valve gap 2 is connected first spring 3, primary diaphragm assembly 4 and second valve gap 5 by screw, second valve gap 5 is connected second spring 10, secondary diaphragm assembly 6 and valve body 7 by screw, sentinel valve is connected with gas bag (branch gas tank) by bolt, has Sealing 8 to be used to guarantee sealability between sentinel valve and the gas bag (branch gas tank) on the valve body.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of novel submerged sentinel valve simple in structure to be provided.
The purpose of this utility model can be achieved through the following technical solutions: novel submerged sentinel valve, this sentinel valve comprises guide's part, first valve gap, second valve gap, first spring, second spring, the primary diaphragm assembly, the secondary diaphragm assembly, valve body, Sealing, described first guide structure is connected with valve gap, described first valve gap is connected with second valve gap, described first spring and primary diaphragm assembly are located between first valve gap and second valve gap, described first spring is pressed on primary diaphragm assembly top, described second valve gap is connected with valve body, described second spring, the secondary diaphragm assembly is located between second valve gap and the valve body, described second spring is pressed on secondary diaphragm assembly top, described valve body is provided with Sealing, it is characterized in that, described Sealing is provided with semi-enclosed chamber, described valve body is provided with passage, in the chamber and valve body of this channel connection Sealing.
Described sentinel valve is connected with gas bag, and described chamber communicates with gas bag by the passage on the valve body.
The cross section of described chamber is U-shaped or V-arrangement.
Compared with prior art, the utility model has substituted original O RunddichtringO with novel Sealing, thereby has guaranteed the sealability between sentinel valve and the gas bag (branch gas tank) more.
Description of drawings
Fig. 1 is the structural representation of the submerged sentinel valve of prior art;
Fig. 2 is the structural representation of novel submerged sentinel valve of the present utility model;
Fig. 3 is one of the cross sectional representation of the Sealing of novel submerged sentinel valve of the present utility model;
Fig. 4 be novel submerged sentinel valve of the present utility model Sealing cross sectional representation two.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in Fig. 2～4, this novel submerged sentinel valve is made up of guide's part 1, first valve gap 2, second valve gap 5, first spring 3, second spring 10, primary diaphragm assembly 4, secondary diaphragm assembly 6, valve body 7, Sealing 9 etc.Guide's part 1 can directly be connected on first valve gap 2 by screw, also can be connected with first valve gap 2 by tracheae, first valve gap 2 is connected first spring 3, primary diaphragm assembly 4 and second valve gap 5 by screw, second valve gap 5 is connected second spring 10, secondary diaphragm assembly 6 and valve body 7 by screw, sentinel valve is connected with gas bag (branch gas tank) by bolt, substitute original O RunddichtringO with novel Sealing 9 on the valve body, thereby guaranteed the sealability between sentinel valve and the gas bag (branch gas tank) more.
The structure of Sealing 9 is that it has a semi-enclosed chamber I, and chamber I communicates with gas bag (branch gas tank) by the passage II on the valve body 7, pressurized air in the gas bag (branch gas tank) enters the chamber I of Sealing 9, make Sealing produce extrusion-deformation according to the compressed-air actuated pressure of selfsealings principle, guaranteed sealability between sentinel valve and the gas bag (branch gas tank) thereby reach seal pressure.The cross section of chamber I is U-shaped or V-arrangement, and perhaps some other special-shaped shape all can.
