Abstract
The invention discloses a gas variety selecting valve, which comprises a valve body and a valve cover, wherein the valve body comprises at least two channels namely a first channel and a second channel; a stop block and a spring sleeved on the lower end part of the stop block are arranged in the channels respectively; the elastic force of the spring in the first channel is smaller than that of the spring in the second channel; and the stop block moves under a gas pressure to stop or open the channels. The gas variety selecting valve has a simple structure, and can be used for substituting the original manual gas variety change to perform automatic gas variety selection.
Description
Technical field
The present invention relates to a kind of gas kind selector valve, the gas kind selector valve that the pressure difference is selected automatically during particularly a kind of can the input according to gas.
Background technique
The present kind that on the apparatus that can use multiple gases, generally adopts pipeline independently to come the gas that the district office enters, if when having two kinds of gases to select to insert, the gas that needs the manual tune suction valve and select corresponding pipeline to insert was both wasted time and energy, and also lacked safety.So existing market lacks a kind of device, this device can change at any time and determine gas port automatically and carry out the gas kind according to this and select automatically according to the input gas with various.
Summary of the invention
For solving the problems referred to above that prior art exists, the invention provides a kind of gas kind selector valve, it is simple in structure, substitutes original artificial replacing identification gas kind, can select to recognize the gas kind automatically.
The present invention can be solved by the following technical programs:
A kind of gas kind of the present invention selector valve, it comprises a valve body and valve gap, valve gap is provided with a suction port; Comprise two passages that are respectively first passage and second channel at least in the valve body, passage connects the air outlet of being located at the valve body bottom respectively; Be respectively equipped with a regulation cock in the passage, this regulation cock rotation is fixed on passage suction port place; Be respectively equipped with a sprue in the passage, its upper end portion penetrates in the regulation cock, its underpart is with a spring, and the elastic force of the spring in the first passage is regulated the elastic force of back less than the spring in the second channel through regulation cock, and sprue is motion obstruction or open channel under the effect of the pressure of gas and spring.
Regulation cock of the present invention is established a protruded stigma, and boss or groove are arranged on the protruded stigma, and this protruded stigma penetrates and is fixed in the via hole on the valve gap.
Spring of the present invention lower end is fixed by a fixed block respectively.
Owing to adopt above technological scheme, a kind of gas kind selector valve of the present invention by different springs is set, makes the change difference of spring when the input gas with various, and therefore, the passage difference of unlatching is carried out the selection identification of gas kind.

Among the figure 1, valve gap; 2, valve body; 3, the pressure regulation bolt; 4, sprue; 5, the first springs; 6, fixed block; 7, sealing gasket; 8, the second springs; 9, O type circle; 10, protruded stigma.
Embodiment
Below in conjunction with embodiment, further set forth the present invention:
Shown in Figure 1, a kind of gas kind of the present invention selector valve, it comprises a valve body 2 and valve gap 1, establish a suction port on the valve gap 1, two air outlets are arranged at valve body 2 bottoms, comprise in this valve body 2 that at least two passages are respectively first passage and second channel, those passages connect one of them air outlet respectively, be respectively equipped with a sprue 4 and in the passage and be enclosed within the spring 5 and 8 of sprue underpart, first spring, 5 elastic force in the first passage are less than second spring, 8 elastic force in the second channel, and sprue 4 move under gas pressure obstruction or open channel.Also comprise a regulation cock 3 in two passages respectively, this regulation cock rotation is fixed on passage suction port place, and the upper end portion of sprue 4 can penetrate in the regulation cock.Regulation cock can rotate and move up and down the compression dynamics that changes spring, is rotated down and makes spring compression, rotates up the length of spring compressed dynamics is reduced; And maintain static by fixed block 6 in the lower end of spring 5 and 8.Valve body 2 is provided with the valve gap 1 of bringing gas port into, and 2 of this valve gap 1 and valve bodies pass through sealing gasket 7 sealing and fixing.
As the second embodiment of the present invention, said structure does not change except that regulation cock, above-mentioned regulation cock not only rotates and is fixed in the passage, also establishes the protruded stigma 10 of a hollow, and this protruded stigma 10 penetrates and by O type circle sealing and to be fixed on the valve body upper end cap be in the via hole on the valve gap 1.Whether the protruded stigma design of this regulation cock makes things convenient for the test of whole valve body, make things convenient for the set compression dynamics of detection springs can change under the effect of input gas pressure.
Working principle of the present invention is: when the inlet end of valve inserted rock gas, gas entered from the hole of pressure regulation bolt, and (structure in the first passage is called a * *; Structure in the second channel is called the 2nd * *, respectively as follows) strength of first spring a little less than, the second spring strength is strong and be in compressive state, first spring stress begins to take place deformation, and gas promotes first sprue, and enters the outlet side of valve body by the gap between first sprue and the pressure regulation bolt, because gas pressure is lower, the elastic force strength of second spring is greater than gas pressure, so gas can not promote second sprue, can't enter the valve body outlet side.
When the inlet end of valve inserts liquid gas, gas enters from the hole of pressure regulation bolt, this moment first spring strength a little less than, be subjected to higher pressure and begin compression, the motion of first sprue is also blocked the air outlet, and is subjected to the effect of gas pressure, makes the motion of second sprue, compress second spring, gas enters the outlet side of valve by the gap between second sprue and the pressure regulation bolt.
By regulating pressure that the pressure regulation bolt changes spring to adapt to the gas kind of different pressures, under the state that does not have gas to feed, valve body is in closed state.
By above technology, a kind of gas kind selector valve of the present invention can be selected gas port automatically according to input gas kind different pressures, substitutes and selects identification gas kind artificially.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
