Abstract
The utility model relates to a negative pressure self-closing oil gun which is matched with a fuel metering oiling machine, wherein, when a hand lever is pushed aside, the oil gun can fill oil and suck in air. The utility model is characterized in that in an existing main valve, a sealing device arranged on the opening end of the main valve fixedly presses a sealing element so that the sealing element is sealed by a screw bolt through a spring and an upper and a lower pressing covers. The aim of the utility model is to keep the stability of the sealing performance of the oil gun, and at the same time, the oil gun is easy for maintaining. The utility model has the advantages that the oil is not easy to leak, the service life of the sealing element is long, the maintenance rate of products is low, etc.
Description
The utility model relates to a kind of and the supporting use of fuel metering fuel charger, tiller back down, oiling is air-breathing, negative pressure self-sealing nozzle.
At present, at each petrol service station and the matching used self-sealing nozzle of fuel metering fuel charger, its structure includes handle, main valve, negative pressure self-packer, reflux valve, tracheae, oil outlet pipe, and wherein handle heads on the push rod of main valve; The secondary valve chamber of rifle body in the negative pressure self-packer stretches to the exit end of oil outlet pipe by tracheae and communicates with atmosphere, and self-styled push rod and handle are movably hinged.The primary-valve port sealing arrangement is fixed sealing by upper and lower gland to O-ring seals by trip ring, because refueling, uses frequently the self-sealing nozzle, upper and lower the moving of the push rod of main valve causes the trip ring location not press tightly sealing member easily, sealing member and sealed 's closed intensity is reduced, influence its leak tightness, make nozzle leakage of oil often occur, and adopt trip ring, bring inconvenience for adjusting, maintenance loading and unloading sealing member as fastener.
The purpose of this utility model is stable, the easy to maintenance self-sealing nozzle of a kind of sealing property of design.
In order to achieve the above object, the utility model is finished by the following technical solutions: in the main valve that is contained, its port sealing device by bolt by spring, upper and lower gland to the sealing member sealing that is fixed and clamped.After the self-sealing nozzle frequently uses a period of time, though sealing member and sealed 's closed intensity is affected, but under the effect of initial tension of spring, sealing member and sealed face can remain closed contact, make nozzle keep excellent sealing performance; Simultaneously, the sealing device adopts bolt as fastener, brings convenience for maintenance loading and unloading, adjusting.
The utility model compared with prior art has the following advantages:
1, good seal performance;
2, maintenance loading and unloading, easy to adjust;
3, prolonged the service life of sealing member;
4, not easy oil leakage.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the present embodiment front view.
As shown in Figure 1, present embodiment includes handle (1), main valve (11), negative pressure self-packer (10), reflux valve (9), tracheae (8), oil outlet pipe (5), and position annexation between them and structure are prior art, no longer describes here.Main valve (11) port sealing device by bolt (2) by spring (6), upper and lower gland (5) to sealing member (3) sealing that is fixed and clamped.Sealing member (3) is＜the shape seal ring lip of seal ring and sealed contact surface to be strengthened, thereby guarantee the leak free reliability.After the self-sealing nozzle frequently uses a period of time, though sealing member (3) is affected with sealed closed intensity, but under the effect of spring (6) predetermincd tension, sealing member and sealed face remain closed contact, make the self-sealing nozzle keep excellent sealing performance on the one hand, not easy oil leakage makes seal durability obtain prolonging on the other hand, has reduced the product maintenance rate; Adopt bolt as fastener simultaneously, bring convenience for maintenance loading and unloading, adjusting.
Claims (2)
1, a kind of self-sealing nozzle comprises main valve, it is characterized in that in the main valve that is contained, its port sealing device by bolt (2) by spring (6), upper and lower gland (5) to sealing member (3) sealing that is fixed and clamped.
2, self-sealing nozzle according to claim 1 is characterized in that sealing member (3) is＜the shape seal ring.
