Abstract
The utility model belongs to a fire-retardant ventilation device of a vertical oil tank with a fixed roof. The fire-retardant ventilation device is characterized in that a pressure valve disc and a vacuum valve disc are arranged side by side. The pressure valve disc, the vacuum valve disc and a fire retardant bed are arranged on the same shaft and are positioned in a valve body. Membrane slices at the lower part of the valve discs, a valve seat, the outer sleeve of the shaft of a guide rod, the inner sleeve of a guide seat are made of polytetrafluoroethylene. The fire retardant bed is a stainless steel waviness folding ribbon structure. The valve of the utility model combines a breather valve and a water stop device. The utility model has the advantages of good performance for ventilation and fire retardant, light weight, compact structure and low cost. The utility model is suitable for being used by a vertical oil tank with a fixed roof for crude oil and clean oil.
Description
The utility model belongs to vertical fixed top oil storage tank fire prevention ventilation equipment.
Existing vertical fixedly top crude oil and light oil oil storage tank all are equipped with tank valves and oil tank flame trap simultaneously for the needs of the ventilation safety of preventing fires, and play the effect of ventilation and fire safety respectively.For this reason, the court had once designed novel tank valves and novel flame arrester for petroleum tank, and had applied for Chinese patent, and its patent No. is respectively CN89215258 and CN87204838.Though the performance of these two kinds of patented products is good, the two adopt simple overlaying structure form also can reach simultaneously the fire prevention ventilation safety double action, but since the two be superimposed simply, not only weight is considerable, and physical dimension is big, and cost is also than higher.
The purpose of this utility model is to design a kind of can the ventilation, and organic association that again can back-fire relief not only has good ventilation and back-fire relief performance, and have in light weight, compact structure, the characteristics that cost is low.
For achieving the above object, the utility model oil tank fire prevention inhalation valve is made up of valve body, pressure valve disc, vacuum valve disc, flame retardant bed etc., its pressure valve disc and vacuum valve disc adopt abreast-type to arrange, pressure valve disc and flame retardant bed are that coaxial-type is arranged, the three places a valve body altogether, its flame retardant bed is positioned at lower housing portion, is a drawer type structure that tilts; The protective housing of valve body malleation relief opening adopts spherical structure, and the negative inspiratory pressure mouth adopts horn mouth formula structure; Polytetrafluoroethylene diaphragm is adopted in pressure valve disc and vacuum valve disc below, and valve seat adopts polytetrafluoroethylmaterial material, with guide rod shaft polytetrafluoroethylene bushing is arranged all outward in the guide holder; The guide holder bottom is provided with two exhaust ports; Its flame retardant bed is stainless steel ripple folding belt structure, and flame retardant bed shell upper end is provided with four spring sheets and stiffening ring.
The utility model is owing to be designed to an organic co-ordinative construction with inhalation valve and flame trap, valve disc diaphragm, valve seat and lining adopt polytetrafluoroethylmaterial material, flame retardant bed adopts stainless steel ripple folding belt structure, thereby not only have good ventilation and a back-fire relief performance, and have in light weight, compact structure, characteristics that cost is low, simultaneously also be convenient to maintenance and repair, and have the usability of all-weather.
Structure and embodiment to the utility model oil tank fire prevention inhalation valve does to describe in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural drawing of oil tank fire prevention inhalation valve
Fig. 2 is valve body figure
Fig. 3 is valve disc and guide holder skate machine composition
Fig. 4 is the flame retardant bed structural drawing
Structure such as Fig. 1 of the utility model oil tank fire prevention inhalation valve, form by valve body (1), flame retardant bed (2), valve seat (3), pressure valve disc (4), directional post (5), guide holder (6), protective housing (7), ground wire (8), guide rod shaft (9), vacuum valve disc (10) etc., its pressure valve disc (4) and vacuum valve disc (10) adopt abreast-type to arrange, pressure valve disc (4) and flame retardant bed (2) are coaxial arrangement, the three places a valve body (1) altogether, detailed structure such as Fig. 2 of valve body (1).The protective housing of the malleation relief opening of valve adopts spherical structure, the negative inspiratory pressure mouth adopts horn mouth formula structure, whole runner is short, smooth, resistance is little, adopt its pressure valve disc (4) and vacuum valve disc (10) below has polytetrafluoroethylene diaphragm well antifreeze, antiseptic property, and valve seat (3) adopts polytetrafluoroethylmaterial material.
As shown in Figure 3, be provided with formation one ring shaped air-cushion between an annular groove (11) and the diaphragm on the valve disc, the elasticity and the sealing of diaphragm have been increased, for guaranteeing that valve disc can normally slide up and down under the plug cool condition, polytetrafluoroethylene bushing is all arranged in the guide holder (6) and outside the guide rod shaft (9), for reducing valve disc take-off resistance, the bottom of guide holder (6) is provided with two exhaust ports (12).
As shown in Figure 1, the flame trap of valve body lower portion is a drawer type structure that tilts, and gathers and freezes in that flame retardant bed is lip-deep in order to reducing lime set, conveniently checks and cleans.As shown in Figure 4, its flame retardant bed (2) has good back-fire relief performance for stainless steel ripple folding belt structure, and flame retardant bed shell upper end is provided with four spring sheets (13) and stiffening ring (14) simultaneously, itself and housing are compressed, avoided the gas short circuit to guarantee the back-fire relief performance.
Its course of action is seen Fig. 1, Fig. 2, when jar internal pressure during greater than the inhalation valve cracking pressure, pressure valve disc (4) is opened, and is slided up and down by guide rod shaft (9), directional post (5) and guide holder (6) control valve disc, and the gas of exhalation drains into atmosphere by flame retardant bed (2) along the protective housing lower limb; When jar internal pressure during less than cracking pressure, valve disc falls after rise to valve seat again.Equally, when negative pressure value in the jar during greater than inhalation valve negative pressure cracking pressure, vacuum valve disc (10) is opened, guide rod shaft (9) by vacuum valve disc (10), directional post (5) and guide holder (6) control valve disc slide up and down, air sucks from vacuum valve seat below horn mouth, and enters in the jar by flame retardant bed (2); Go up when the jar internal pressure, when making it less than vacuum valve disc cracking pressure, the vacuum valve disc falls back to valve seat.
The model machine that manufactures and designs according to the utility model has carried out positive negative pressure ventilation experiment, its result meets the regulation of petroleum industry ministerial standard SYJ1018-82, the result that flame retardant bed is partly measured meets the regulation of GB GB5908-86, so the utility model can be widely used on the crude oil and light oil fixed roof tank of oil refinery under the various weather conditions, oil depot.
