Abstract
The utility model relates to a pulse valve for rotating and spraying to remove dust. The pulse valve consist of a leading mechanism, a valve cover, a spring and a membrane component, wherein the leading mechanism is connected to the valve cover through screws; the membrane component is arranged below the spring; the spring and the membrane component are connected to an air pocket or an air separating box by the valve cover through screws; and the spring is a truncated cone-shaped spring. Compared with the prior art, the utility model has the advantages that: the truncated cone-shaped spring has excellent stability, and influence on the spring force caused by opening/closing stroke limit of the pulse valve structure and the membrane component is effectively avoided, so that the opening/closing property of the pulse valve and the stability of the membrane component in the opening/closing process are enhanced and the best spraying effect is achieved.
Description
Technical field
The utility model relates to sentinel valve, especially relates to a kind of sentinel valve that is used for the rotary blowing dedusting.
Background technique
The sentinel valve that is used for the rotary blowing dedusting is a kind of of sentinel valve; Be mainly used on the large-scale rotary blowing 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.
The big spring of customary this product is the cylinder type pressure spring; Because this product bore is generally more than 6 o'clock; The diaphragm unit area is very big; Limitation on the stability of helical spring makes diaphragm unit in the process that opens and closes motion, also be prone to wild effect takes place, and distribution of gas instability or tolerance that causing jets are not enough, finally cause ash-removal effect not good.
Simultaneously, the decrement of helical spring receives sentinel valve structure and diaphragm unit to open and close the restriction of stroke, and its number of turns and helical pitch are also received restriction, make the switch performance of sentinel valve receive very big influence.
The model utility content
The purpose of the utility model is exactly switch performance and the stability winding-up effect good sentinel valve that be used for rotary blowing dedusting of reinforcing membrane chip module in opening-closing process that a kind of intensifier pulse valve is provided for the defective that overcomes above-mentioned existing technology existence.
The purpose of the utility model can realize through following technological scheme:
A kind of sentinel valve that is used for the rotary blowing dedusting; Constitute by guide mechanism, valve gap, spring and diaphragm unit; Described guide mechanism is connected on the valve gap through screw, and described diaphragm unit is located at the below of spring, and valve gap is connected gas bag through screw with spring and diaphragm unit or divides on the gas tank; It is characterized in that described spring is the frustoconic shape spring.
The end face of described frustoconic shape spring is connected with the valve gap contact, and the bottom surface is connected with the diaphragm unit contact.
The cone-apex angle of described frustoconic shape spring is 5 °～50 °.
Compared with prior art; The utility model; With the helical spring of cone type spring replacement custom, its characteristics are that the frustoconic shape spring has advantages of excellent stability on the crucial keying execution architecture of sentinel valve, and have effectively evaded the influence of sentinel valve structure and the diaphragm unit keying spring force that travel limits caused; Thereby the switch performance of intensifier pulse valve and the stability of reinforcing membrane chip module in opening-closing process reach best winding-up effect.
Description of drawings
Fig. 1 is the structural representation of common submerged winding-up dedusting with sentinel valve;
Fig. 2 is the structural representation of the utility model.
1 is that guide mechanism, 2 is that valve gap, 3 is that spring, 4 is diaphragm unit among the figure.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Comparative Examples
Sentinel valve is used in submerged winding-up dedusting; Its structure is as shown in Figure 1; This sentinel valve is made up of guide mechanism 1, valve gap 2, spring 3 and diaphragm unit 4, and guide mechanism 1 is connected on the valve gap 2 through screw, and diaphragm unit 4 is located at the below of spring 3; Valve gap 2 is connected spring 3 and diaphragm unit 4 on gas bag or the branch gas tank through screw, and employed spring 3 is a cylinder-shaped compression spring.
Embodiment
A kind of sentinel valve that is used for the rotary blowing dedusting; Its structure is as shown in Figure 2; This sentinel valve is made up of guide mechanism 1, valve gap 2, spring 3 and diaphragm unit 4, and guide mechanism 1 is connected on the valve gap 2 through screw, and diaphragm unit 4 is located at the below of spring 3; Valve gap 2 is connected spring 3 and diaphragm unit 4 on gas bag or the branch gas tank through screw, and employed spring 3 is the frustoconic shape spring.The end face of frustoconic shape spring is connected with valve gap 2 contacts, and the bottom surface is connected with diaphragm unit 4 contacts.The cone-apex angle α of frustoconic shape spring is 5 °～50 °, and cone-apex angle α is 10 ° in the present embodiment.The helical spring of on the crucial keying execution architecture of sentinel valve, being accustomed to the replacement of cone type spring; The frustoconic shape spring has advantages of excellent stability; And effectively evaded the influence that sentinel valve structure and diaphragm unit open and close the spring force that travel limits caused; Thereby the switch performance of intensifier pulse valve and the stability of reinforcing membrane chip module in opening-closing process reach best winding-up effect.
