According to the automatic exhaust device, gas in a small pump can be discharged and automatic exhaust can be well achieved, and the structure is simple, and the installation and the operation are convenient.
Description
Technical field
The utility model relates to a kind of venting gas appliance, particularly a kind of automatic discharge device of pump seal intracavity gas.
Background technique
The method for exhausting of existing pump normally arranges floss hole in the Seal cage upper end of pump, when not using at ordinary times, just do not block with pipe plug, and when needing to use, artificial exhaust before pump.
Referring to Fig. 2, the vent systems that it is depicted as the combination of employing standard pipe fitting Figure 3 shows that the common vent systems with stop valve, Figure 4 shows that the vent systems of not being with stop valve, and these vent systems are because its structural feature can't be applied to little pump.
For little pump, because its limited space, even the gas exhaust piping that the small dimension pipe fitting forms also can't be installed, so the gas that causes producing in those little pumps can not well discharge, easily at the Seal cage inner accumulated gas of pump, thereby cause the dry friction of mechanical seal, and then seal failure.
The model utility content
The utility model can not well discharge in order to solve the gas that produces in the above-mentioned little pump, thereby causes the problem of seal failure, and a kind of automatic exhaust device is provided.
In order to achieve the above object, technical solutions of the utility model are as follows:
A kind of automatic exhaust device, comprise outlet pipe, stop valve and automatic control pressure vent, described automatic exhaust device also comprises two screw socket elbows, two screw socket pipe collar, joint, one end of described pair of screw socket elbow is connected with the Seal cage of pump, the other end of two screw socket elbows joins by an end of two screw socket pipe collars and outlet pipe, described stop valve is arranged on the outlet pipe, and the other end of described outlet pipe joins by joint and automatic control pressure vent.
In preferred embodiment of the present utility model, described venting gas appliance also comprises support, and described support connects the pump housing and outlet pipe.
Further, described stop valve is in normally open.
The utility model can be so that little pump also can be realized automatic vent well, and it is simple in structure, fitting operation convenient.
Simultaneously, the utility model also is fit to the automatic vent of other similar devices.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation;
Fig. 2 is the vent systems schematic representation of employing standard pipe fitting combination;
Fig. 3 is the common vent systems schematic representation with stop valve;
Fig. 4 is not for the vent systems schematic representation of stop valve.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the automatic exhaust device that the Seal cage gas that can be fit to miniature pump 1 that it is depicted as the utility model provides is discharged automatically, this device comprise two screw socket elbows 2, two screw socket pipe collar 3, outlet pipe 4, stop valve 5, joint 6, automatic control pressure vent 7 and support 8.
Wherein, two screw socket elbows 2 adopt stainless-steel seamless pipe to bend, and can reduce bulk like this, are fit to and are connected pump 1 connect, and the one end is communicated with the Seal cage of pump 1, and the other end passes through pair screw socket pipe collars 3 and is communicated with outlet pipe 4.Like this, the gas in pump 1 Seal cage is discharged in the outlet pipe 4 by two screw socket elbows 2.
Two screw socket pipe collars 3, match with two screw socket elbows 2, it is to play a connection function, outlet pipe 4 can be flexibly connected by itself and two screw socket elbows 2, dismounting that so just can easy to exhaust pipe 4, when outlet pipe 4 damages, can change very easily, not only convenient but also saved cost.
Simultaneously, it can realize again two screw socket elbows 2 independently, so that two screw socket elbows 2 can be by Seal cage with pump 1 assembling, can make so the dismountable assembling of Seal cage of venting gas appliance and pump 1, when not needing exhaust, venting gas appliance can be disassembled, reduce the use wearing and tearing of venting gas appliance, also make things convenient for the use of pump.
Stop valve 5, it is in normally open, is that it specifically is arranged on the outlet pipe 4 for maintenance or replacing outlet valve 7.
Joint 6, be arranged on the top of outlet pipe 4, outlet pipe 4 can be flexibly connected by itself and automatic control pressure vent 7, it can realize being connected with the automatic control pressure vent 7 of distinct interface pattern, like this can be so that people have had more selection in use, can select dissimilar automatic control pressure vent 7 according to different situations, such as when the normal temperature and pressure, can select the automatic control pressure vent 7 of normal temperature and pressure type; During high-temperature pressure, can select the automatic control pressure vent 7 of high-temperature pressure type; During High Temperature High Pressure, can select the automatic control pressure vent 7 of high-temp and-pressure, so that venting gas appliance always is in a best state in use, more be conducive to gas purging like this.
In addition, because the joint 6 of this device can be selected dissimilar automatic control pressure vent 7 according to different situations, so this device not only is fit to the automatic vent of little pump 1, also be fit to the automatic vent of other similar devices.
Automatic control pressure vent 7, its material can adopt brass or stainless steel, and ball float can adopt plastics or stainless steel, prevents that like this outlet valve 7 from getting rusty, and affects exhaust.
In addition, can also install a dismountable pipe additional at automatic control pressure vent 7, when producing toxic gas, can load onto pipe, by pipe toxic gas is discharged into the place of appointment, like this can protection of the environment and Protection personnel healthy.
Because the strength of the Seal cage of pump 1 is very little, in order to prevent that venting gas appliance from when being connected with pump 1, damaging Seal cage by pressure, cause Leakage Gas, be provided with a fixing frame 8 at venting gas appliance, it is horizontally placed between outlet pipe 4 and the pump 1, and venting gas appliance is fixed on the pump 1 by it.
In the venting gas appliance that forms thus, two screw socket elbows 2, two screw socket pipe collar 3 and outlet pipe pipe 4 have formed 7 passages that rise from the Seal cage to the automatic control pressure vent, outlet pipe 4 can tilt to rise at a certain angle, is convenient to like this gas and can enters smoothly automatic control pressure vent 7 eliminatings.
Based on above-mentioned principle, the utility model implementation is as follows:
When in the Seal cage of pump 1 γ-ray emission being arranged, gas can enter into outlet pipe 4 by two screw socket elbows 2, and rises along outlet pipe 4, then, by stop valve 5, the joint 6 of often opening, enters smoothly automatic control pressure vent 7 and gets rid of.When gas is harmful danger medium, can also install pipe additional at automatic control pressure vent 7, gas discharging is arrived the appointed place.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
