Abstract
The utility model relates to a steam inlet valve of a long telescopic soot blower for removing soot and slag from the surfaces of heating furnaces in the petroleum and chemical industry and the power industry and the like. The steam inlet valve comprises a valve seat (2), a valve flap (1), a valve rod (3), a pressure adjusting plate (4) and a locking nut (5), wherein the upper end face of the valve flap (1) is provided with an inverse T-shaped groove (7); corresponding to the T-shaped groove (7), the lower end of the valve rod (3) is provided with a T-shaped head adapted with the T-shaped groove; and the pressure adjusting plate (4) and the locking nut (5) are arranged at the upper end of the valve rod (3). The steam inlet valve has precise internal fit, and the steam outlet pressure is adjustable.
Description
(1) technical field
The utility model relates to a kind of soot blower.Be used for surfaces such as convection bank on the oven, the oven in the power industry, boiler of petrochemical industry, air preheater, economizer superheater and carry out ash disposal, slagging-off.Belong to petrochemical industry, electrical equipment technical field.
(2) background technique
Convection bank on oven in petrochemical industry, the oven in the power industry, the boiler, air preheater, economizer superheater etc., generally all adopt soot blower that ash disposal, slagging-off are carried out in its surface, reduce temperature of exhaust fume, to improve the thermal efficiency of oven, boiler, reach the purpose of energy-conservation of consumption reduction.When cigarette temperature in the stove surpasses 550 ℃, should adopt long flexible soot blower.This soot blower rotates reciprocal fore and aft motion as straight line in burner hearth when blowing ash.When not blowing ash, blow blowing pipe outward in burner hearth outside, can avoid outer when blowing blowing pipe the cigarette temperature is greater than 550 ℃ in stove and the bending that causes like this, there was a mechanical failure thereby cause soot blower.Before the utility model was made, the flexible soot blower of length in the past had the following disadvantages:
1, flap in the air intake valve and valve rod adopt global design, and flap, flap form rigidity with valve seat and contact, when valve rod upwards promotes flap cooperate with valve seat inaccurate, easy generation leakage.
2, the pressure of steam (vapor) outlet is non-adjustable in the air intake valve.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of air intake valve inner cooperate accurate, the length that steam exit pressure the is adjustable soot blower admission valve that stretches.
The purpose of this utility model is achieved in that a kind of length soot blower admission valve that stretches, comprise valve seat, flap, valve rod, pressure adjustment disk and locking nut, the flap upper-end surface is provided with an inverted T-slot, corresponding to this T-slot, the T shape head of cooperation is arranged to patch with it in described valve rod lower end, and described pressure adjustment disk and locking nut are arranged on the valve rod upper end.
The beneficial effects of the utility model are:
1, the flap in the air intake valve adopts with valve rod and separates design, makes flap, flap form flexible the contact with valve seat, guarantees flap and valve seat precision-fit when valve rod upwards promotes, and has prevented leakage.
2, be provided with the pressure adjustment disk in the air intake valve, adjustment disk is made the pressure of the can regulate steam (vapor) outlet of commentaries on classics up and down, make the purging pressure of the soot blower of working position can satisfy the purging requirement, after pressure was regulated and finished, available locking nut locked the pressure adjustment disk.
(4) description of drawings
Fig. 1 is the Facad structure schematic representation of the long flexible soot blower admission valve of the utility model.
Reference character among the figure:
(5) embodiment
Referring to Fig. 1, Fig. 1 is the Facad structure schematic representation of the long flexible soot blower admission valve of the utility model.As seen from Figure 1, described admission valve comprises valve seat 2, flap 1, valve rod 3, pressure adjustment disk 4 and locking nut 5, flap 1 upper-end surface is provided with an inverted T-slot 7, corresponding to this T-slot 7, the T shape head of cooperation is arranged to patch with it in described valve rod 3 lower ends, and described pressure adjustment disk 4 and locking nut 5 are arranged on valve rod 3 upper ends.
Claims (1)
1. one kind long flexible soot blower admission valve, it is characterized in that: described admission valve comprises valve seat (2), flap (1), valve rod (3), pressure adjustment disk (4) and locking nut (5), flap (1) upper-end surface is provided with an inverted T-slot (7), corresponding to this T-slot (7), the T shape head of cooperation is arranged to patch with it in described valve rod (3) lower end, and described pressure adjustment disk (4) and locking nut (5) are arranged on valve rod (3) upper end.
