Abstract
The invention relates to a pulse valve for rotary blowing dedusting. The pulse valve consists of a pilot mechanism, a valve cap, a spring and a diaphragm component, wherein the pilot mechanism is connected to the valve cap through screws; the diaphragm component is arranged below the spring; the valve cap connects the spring and the diaphragm component to an air pocket or a pulse-air manifold through screws; and the spring is a truncated cone-shaped spring. Compared with the prior art, the truncated cone-shaped spring has excellent stability, can effectively avoid influence of spring force from the travel restriction when the pulse valve structure and the diaphragm component are started or stopped, so that the switch performance of the pulse valve and the stability of the diaphragm component during the starting and stopping process are enhanced, and therefore, the best blowing effect can be achieved.
Description
Technical field
The present invention relates to sentinel valve, especially relate to a kind of rotary blowing dedusting sentinel valve.
Background technique
Rotary blowing dedusting sentinel valve is a kind of of sentinel valve, be mainly used on the large-scale rotary blowing sack cleaner, it utilizes the variation of gas pressure to make pressurized gas in the gas bag (minute gas tank) jet in the air chamber of sack cleaner and the solid dust that is attached on the filtering material is broken away from, and is the crucial accessory of sack cleaner.Use widely treating flour dust and assembling sphere with every profession and trade.
The big spring of customary this product is the cylinder type Compress Spring, because this product bore is generally more than 6 o'clock, the diaphragm unit area is very large, limitation on the stability of helical spring makes diaphragm unit in the process that opens and closes motion wild effect occur easily also, the distribution of gas that causing jets is unstable or tolerance is inadequate, finally causes ash-removal effect not good.
Simultaneously, the decrement of helical spring is subjected to 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 large impact.
Summary of the invention
Purpose of the present invention is exactly a kind of switch performance of intensifier pulse valve to be provided and to strengthen the stability winding-up effect good rotary blowing dedusting sentinel valve of diaphragm unit in opening-closing process for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of rotary blowing dedusting sentinel valve, consisted of by pilot mechanism, valve gap, spring and diaphragm unit, described pilot mechanism is connected by screw on valve gap, described diaphragm unit is located at the below of spring, valve gap is connected to spring and diaphragm unit on gas bag or minute gas tank by screw, 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 present invention, replace the helical spring of custom with the cone type spring in the keying execution architecture of sentinel valve key, its characteristics are that the frustoconic shape spring has good stability, and effectively evaded the impact that sentinel valve structure and diaphragm unit open and close the spring force that travel limits causes, thereby the switch performance of intensifier pulse valve and the stability of enhancing diaphragm unit in opening-closing process reach best winding-up effect.
Description of drawings
Fig. 1 is the structural representation that sentinel valve is used in common submerged winding-up dedusting;
Fig. 2 is structural representation of the present invention.
1 is that pilot mechanism, 2 is that valve gap, 3 is that spring, 4 is diaphragm unit among the figure.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Comparative Examples
Submerged winding-up dedusting sentinel valve, its structure as shown in Figure 1, this sentinel valve is made of pilot mechanism 1, valve gap 2, spring 3 and diaphragm unit 4, pilot mechanism 1 is connected by screw on valve gap 2, diaphragm unit 4 is located at the below of spring 3, valve gap 2 is connected to spring 3 and diaphragm unit 4 on gas bag or minute gas tank by screw, and employed spring 3 is cylinder-shaped compression spring.
Embodiment
A kind of rotary blowing dedusting sentinel valve, its structure as shown in Figure 2, this sentinel valve is made of pilot mechanism 1, valve gap 2, spring 3 and diaphragm unit 4, pilot mechanism 1 is connected by screw on valve gap 2, diaphragm unit 4 is located at the below of spring 3, valve gap 2 is connected to spring 3 and diaphragm unit 4 on gas bag or minute gas tank by 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.Replace the helical spring of custom with the cone type spring in the keying execution architecture of sentinel valve key, the frustoconic shape spring has good stability, and effectively evaded the impact that sentinel valve structure and diaphragm unit open and close the spring force that travel limits causes, thereby the switch performance of intensifier pulse valve and the stability of enhancing diaphragm unit in opening-closing process reach best winding-up effect.
