Abstract
The utility model aims at the defects of the easy damage and short service life of the existing air bubble piston and provides a double-head piston used for an air bubble with a long service life. The utility model is characterized in that the two sides of the double-head piston are all provided with a seal surface; the two seal surfaces can be set to be symmetrical and same; when the seal surface at one side can not be used caused by being impacted for a long period, the double-head piston can be changed to another direction and restart working, thereby leading the service life of the main easily damaged part (the piston) in an air bubble product to be prolonged by one time.
Description
Technical field
The utility model relates to a kind of being used for and sprays quick-fried principle with air, prevents and removes all kinds feed bin, hopper, cement preheater kiln and tube furcation place and mine drop shaft, slips the isolated plant of phenomenons such as the material arch camber on slope, sticking storehouse obturation.
Background technology
Industries such as present cement, metallurgy, coal, electric power, mine, coking, iron and steel, in order to prevent and remove the material arch camber on all kinds feed bin, hopper, cement preheater kiln and tube furcation place and mine drop shaft, slide slope, several different methods has been adopted in the appearance of phenomenons such as sticking storehouse obturation, but air bubble is as a kind of Cleaning device for pipeline, it has characteristics such as energy consumption is low, investment is little, easy care, is a kind of desirable broken arch block clearing equipment.Main consumable accessory in the present air bubble product is a piston, need only piston and can not work once bad whole equipment, and the damage of piston mainly is that sealing surface is because long-term damaged in collision causes.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and the air bubble that prolongs a times a kind of service life piston is provided.
The technical solution of the utility model is as follows:
A kind of air bubble double-head piston is characterized in that described double-head piston is that the both sides of piston are equipped with sealing surface.
Two sealing surface symmetries of described piston both sides are identical.
The both sides sealing face of described double-head piston is provided with the annular groove that matches with spring one end.
The real later-model beneficial effect of this usefulness has:
Simple and practical, only piston need be changed a direction and just can rework, thereby make the main consumable accessory piston in the air bubble product prolong one times service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is assembled to the exploded view of air bubble for the utility model.
Fig. 3 is assembled to the cutaway view of air bubble for the utility model.
In the accompanying drawing, 1, the valve body gland; 2, seal ring; 3, spring; 4, dry type bearing; 5, double-head piston; 6, valve body; 7, packing seal; 8, storage tank; 9, piston seat; 10, duplex flange; 11, bolt; 12, annular groove; 13, spring shim; 14, pad; 15, nut.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the piston both sides of the utility model double-head piston 5 all are provided with sealing surface, will continue to use the sealing surface of opposite side after direction of double-head piston 5 transposings under the situation about can can't use because of long-term collision at a side seal face like this.It is identical that the utility model is arranged to symmetry with two sealing surfaces of double-head piston 5 both sides, makes that its both sides sealing face can be general, guaranteed that the cooperation of double-head piston 5 sealing surfaces is tight.
Shown in Fig. 2,3, the utility model double-head piston 5 is positioned at dry type bearing 4 inside with spring 3, and an end of spring 3 is installed in the annular groove 12 of double-head piston 5 sides.Dry type bearing 4 is sealed in a side ports of valve body 6 by valve body gland 1, in order to guarantee leak tightness, also is provided with seal groove on the joint face of valve body gland 1 and valve body 6, is provided with seal ring 2 in the groove.The opposite side port of valve body 6 connects piston seat 9, and piston seat 9 is fixed in the valve body 6 by duplex flange 10.The lateral port of valve body 6 is connected with storage tank 8, is provided with packing seal 7 between their connectivity port, guarantees air-tightness.Above-mentioned valve body 6 and valve body gland 1, duplex flange 10, and storage tank 8 all cooperate with nut 15 and be connected and fixed by spiral shell inspection 11, on bolt 11, also be with spring shim 13 and pad 14.
Other undeclared part that the utility model relates to is same as the prior art.
