Description
Technical field
The utility model relates to a kind of device gathering various gas, is particularly useful for extracting the gas in high negative pressure extraction pipeline.
Background technology
For a long time, the structure of the gas sampler that gas production staff adopts and even shape adopt traditional mode always, unalterable, namely be made up of head, machine barrel, three-way cock (comprising card, spring, hold-down nut), plug, piston, valve rod with a scale, handle, when three-way cock is parallel with stack shell, it is the position of drawing gas sample; When three-way cock is vertical with stack shell, it is the position of supplying gas to gas sample bag or assessor; When three-way cock is in the middle part of above-mentioned two positions, then it is closed condition.But conventional gas samplers exists following shortcoming: 1. the design of inlet, outlet indenture cannot meet operated by personnel's needs, in gas recovery, gas sample bag is not often because contact is closely dropped.2. the different design using threeway rotary switch and card to control gas circuit closes ergonomics, rotary switch can become serious wear because rotating frequently and cause operation effort, in addition, frequent swivel tee switch can make hold-down nut more and more lax even dropping cause card to come off, uncontrollable gas circuit.
Utility model content
The purpose of this utility model is the deficiency overcoming existing gas sampler, provides a kind of push button gas sampler always simply efficient, rational in infrastructure.
The utility model technical solution problem adopts following scheme:
A kind of push button gas sampler, comprise head, three-way cock, machine barrel, piston, plug, valve rod with a scale, handle, wherein head is by air intake opening, gas outlet, threeway slot forms, three-way cock is by rubber case, with the latch of three through holes, spring, scalability leather sheath, stage clip screw forms, described handle, valve rod with a scale, piston connects successively and is installed to machine barrel inside, described plug and machine barrel one end compact siro spinning technology, the other end compact siro spinning technology of described head and machine barrel, described rubber case, scalability leather sheath is positioned at three-way cock top, described spring housing is on the latch of band three through hole, the latch of described band three through hole is positioned at the inside of threeway slot, its bottom stage clip screw is fixed, it is anterior and parallel with machine barrel that described air intake opening is positioned at head, described gas outlet to be positioned in the middle part of head and vertical with machine barrel.Its design feature is: described air intake opening, outside, gas outlet are for oval; Described band three through hole latch is arranged on threeway slot, and its shape becomes right cylinder, at varying cross-section place, being through hole in 90 ° more nearby apart from button, apart from button remotely for becoming 180 ° of through holes, controlling gas flow through route by the mode of button.
The utility model design feature is also:
The material of described scalability leather sheath is any one in resistance to acids and bases plastic material.
The aperture of described air intake opening, gas outlet gas flow warp is equal with the pore size on three-way cock.
Further, three-way cock can downwards by maximum displacement equal the vertical range of two place's aperture cross-sectional.
The beneficial effects of the utility model are: the utility model controls gas circuit by push button three-way cock on the one hand, on the other hand by changing the shape of inlet, outlet, effectively solve the untight problem of contact opening.Be widely used in extraction workload large, under the environment that extraction negative pressure is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is head section structural representation of the present utility model.
Fig. 3 is three-way cock structural representation of the present utility model.
Number in the figure: 1, head 2, three-way cock 3, machine barrel 4, piston 5, plug 6, valve rod 7 with a scale, handle 8, air intake opening 9, gas outlet 10, threeway slot 11, rubber case 12, the latch 13 with three through holes, spring 14, scalability leather sheath 15, stage clip screw 16, through hole in 90 ° 17, one-tenth 180 ° of through holes.
The utility model is described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1-Figure 3, a kind of push button gas sampler is made up of head 1, three-way cock 2, machine barrel 3, piston 4, plug 5, valve rod 6 with a scale, handle 7; Wherein head comprises air intake opening 8, gas outlet 9, threeway slot 10; Three-way cock comprises rubber case 11, latch 12 with three through holes, spring 13, scalability leather sheath 14, stage clip screw 15, through hole 16 in 90 °, becomes the through hole 17 of 180 °;
As further improvement, the material of retractility leather sheath 14 is any one of resistance to acids and bases plastic material.
Air intake opening 8 is equal with the pore size on three-way cock 2 with the aperture of gas outlet 9 gas flow warp.
Three-way cock 2 can downwards by maximum displacement equal through hole 16 in 90 ° and the vertical range of through hole 17 place xsect becoming 180 °.
The principle of work of the present embodiment and using method
(1) sample is fashionable
When three-way cock 2 be in do not press state time, after the proofed sleeve in air intake opening 8 and gas production place, gas outlet 9 are connected with gas sample bag, pull handle 7 to drive piston 4 to move by valve rod 6, it is inner that gas enters machine barrel 3 by air intake opening 8, and now collector is in sample and enters state.
(2) when sample goes out
When three-way cock 2 be in press state time, driving handle 7 drives piston 4 to move by valve rod 6, and gas enters gas sample bag by machine barrel 3 inside through gas outlet 9, and now collector is in sample and does well.
The principle of work of the present embodiment three-way cock 2 and using method
After being combined with spring 13 by the latch 12 of band three through hole, insert threeway slot 10 and stage clip screw of screwing on.If when not pressing rubber case 11, gas by path be: the through hole 17-machine barrel 3 of air intake opening 8-become 180 °, now for sample enters state; If when pressing rubber case 11, gas by path be: through hole-gas outlet 9-gas sample bag of machine barrel 3-in 90 °, now for sample does well.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment to invention has been detailed description, the person skilled of this area is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the present utility model technical scheme, it all should be encompassed in right of the present invention.
