Abstract
The utility model relates to an anti-explosion isolating valve, which comprises an air inlet pipe connector and a three-way connecting pipe, wherein one end of the three-way connecting pipe is in seal connection with the air inlet pipe connector by an isolating single-way valve, the other end of the three-way connecting pipe is connected with an air inlet of a dedusting main machine, and an explosion release single-way valve is arranged on a third interface of the three-way connecting pipe in a sealing way. The anti-explosion isolating valve has the advantages that the structure is simple, and the use is convenient; in addition, the anti-explosion isolating valve prevents the operators from being hurt by the dust explosion of the dedusting main machine; therefore, the anti-explosion isolating valve is applied to the transformation on the existing anti-explosion isolating valve.
Description
Technical field
The utility model relates to a kind of separating valve, particularly a kind of explosion-proof separating valve.
Background technique
In the industrial premises dust pelletizing system, extensively adopt the negative pressure dust collecting system, the blower fan of dedusting main frame produces suction force, and by dust shield with take out the dirt pipeline and industrial dust is extracted in the dedusting main frame filters, industrial dust is collected in the ash collection bucket of dedusting main frame.Some industrial dust belongs to combustible material, and dust accumulates in the main frame, if temperature is higher or system has sucked Mars, may cause dust combustion even blast.If dust explosion in the main frame, the impact force of generation can enter into takes out in the dirt pipeline, and arrives dust-sucking hole by pipeline, and dust-sucking hole generally is operator at one's side, and the impact force of blast will produce personal injury to operator.
The explosion-proof separating valve structure of Cai Yonging in the past, all be greater than the cleaning shaft diameter at the caliber that the one-way valve position is installed, after one section operation in period, the place that caliber is big is slower because of flow velocity, dust will be deposited on the position that one-way valve is installed, and the dust of deposition can cause the one-way valve open and close to be obstructed, when dust explosion occurring, one-way valve can not normally be closed, and does not have explosion-proof buffer action.
The model utility content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, easy to use, prevent that dedusting main frame dust explosion from producing the explosion-proof separating valve of personal injury to operator.
A kind of explosion-proof separating valve, comprise the suction tude joint, also comprise t-joint, be tightly connected by isolating one-way valve between one end of described t-joint and the described suction tude joint, the other end of described t-joint is connected with the intake grill of dedusting main frame, is sealed and installed with the venting of dust explosion one-way valve on the three-way interface of described t-joint.
In the utility model, described t-joint is that skew T is taken over, and described venting of dust explosion one-way valve is installed on the inclined pipe of described t-joint.
In the utility model, the caliber of described t-joint is identical with the dust pelletizing system pipe diameter.
Adopt such scheme; the utility model is when work; the dust air-flow flows to the main frame connecting flange from the suction tude joint; under the stream pressure effect; isolate one-way valve opens; because the dedusting main frame is when work; take out and be negative pressure state in the dirt pipeline; the venting of dust explosion one-way valve is a closed condition, if combustion explosion appears in dust in the dedusting main frame, and the anxious poly-increase of the pressure that main frame is interior and explosion-proof separating valve is interior; isolate closed check valve; venting of dust explosion one-way valve opens, pressure are let out and are removed, and the protection dust pelletizing system is without prejudice; protection operator's safety; and the utility model t-joint caliber is consistent with the dust pelletizing system pipe diameter, has prevented the position deposition dust of explosion-proof separating valve, has guaranteed the proper functioning of explosion-proof separating valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing 1: 1----suction tude joint, 2----first bolt, 3----isolate one-way valve, 4----sealing gasket, 5----t-joint, 6----main frame connecting flange, 7----venting of dust explosion one-way valve, 8----second bolt.
Embodiment
Below in conjunction with accompanying drawing, describe a kind of embodiment of explosion-proof separating valve in detail.
As shown in Figure 1, the utility model t-joint 5 is that skew T takes over, and at an end of t-joint 5 the main frame connecting flange is installed, and the other end will isolate one-way valve 3 with first bolt 2 and suction tude joint 1 links together.Be mounted with venting of dust explosion one-way valve 7 with second bolt 8 on the inclined pipe of t-joint 5.In the both ends of the surface of isolating one-way valve sealing gasket 4 is installed.
Working procedure of the present utility model and principle are:
Main frame connecting flange 6 is installed on the intake grill of dedusting main frame, suction tude joint 1 system of being connected in takes out on the dirt pipeline, and dust pelletizing system is when work, and the dust air-flow flows to main frame connecting flange 6 from suction tude joint 1, under the stream pressure effect, isolate one-way valve 3 and open.Be negative pressure state in the dirt pipeline because the dedusting main frame when work, is taken out, the venting of dust explosion one-way valve is a closed condition.If combustion explosion appears in dust in the dedusting main frame, with interior anxious poly-the increasing of pressure of explosion-proof separating valve, isolation one-way valve 3 is closed in the main frame, the venting of dust explosion one-way valve opens, and pressure is let out and is removed, and protects dust pelletizing system to be without prejudice, protection operator's safety.
The caliber of t-joint 5 is consistent with the dust pelletizing system pipe diameter, when guaranteeing the dust pelletizing system operation, the air-flow velocity in the t-joint 5 with take out the dirt pipeline in flow velocity consistent, can not deposit dust in the t-joint 5, isolation one-way valve 3 is switch flexibly.
