Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of gas column control type big orifice stop valve.
Background technique
Valve is extensive use in the industry, the valve of prior art is mainly by valve body, spool and valve rod composition, its by valve rod realize spool in valve body action so that complete valve body break-make control, but when being used in big orifice, the more difficult realization of valve of prior art controls, in order to solve this technical problem, China Patent Publication No. is 102797869 disclose a kind of big orifice stop valve, it mainly increases balloon in the passage of valve body, by inflating to balloon, make valve body realize break-make to control, so its control stability is poor in actual applications, because balloon maintains by air pressure, when the hydraulic pressure in big orifice is larger, the air pressure of balloon is just not enough to the object reaching control, stability in use is poor, be difficult to the demand meeting market.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the gas column control type big orifice stop valve that stability in use is good.
The technological scheme realizing the utility model object is a kind of gas column control type big orifice stop valve, comprise valve body, be arranged on the control valve plate of described valve body, the inwall of described valve body is provided with control valve plate and moves cavity, be equipped with at the top of the inwall of described valve body and bottom and control horizontal chamber, the top of described control valve plate and bottom are equipped with and control projection, described control projection is arranged in the horizontal chamber of described control, barometric column and Returnning spring is provided with in the horizontal chamber of described control, described barometric column and described Returnning spring are separately positioned on and control protruding both sides, and the two ends of Returnning spring are connected to the inwall that controls horizontal chamber respectively and control in projection, the sidewall of described valve body is provided with pressure channel, tracheae is provided with in described pressure channel, one end of described tracheae and the inlet end of described barometric column seal fixing, source of the gas is provided with outside described valve body, described tracheae is connected on source of the gas by control valve.
The length of described barometric column is identical with the length in the horizontal chamber of described control.
Described tracheae is provided with pneumatic indicator.
Rubber spacer is provided with between described control projection and described barometric column.
Its working principle is summarized as follows: in use, open control valve, external air source is made to enter in barometric column by tracheae, because the air pressure entering barometric column increases gradually, therefore barometric column can expand gradually, and then the control projection promoting to control valve plate moves in the horizontal chamber of control, and the spring that gradually reduces, control valve plate is progressed in mobile cavity, realize valve body to open, realize fluid circulation, when needs are closed, give barometric column pressure release gradually, now the reposition force of Returnning spring is greater than the pressure of barometric column, therefore control projection resets gradually under the effect of Returnning spring, and then make control valve sheet reset, complete to disconnect and control.
The utility model has positive effect: structure of the present utility model is simple, by coordinating of barometric column and Returnning spring, can realize controlling the break-make of valve body, simultaneously due to the given volume of barometric column, the action controlling valve plate can be completed by little air pressure, rapid operation and convenient, compare the circulation and disconnection that adopt balloon control valve body, its control stability is stronger, when hydraulic pressure for big orifice is larger, still accurately can complete break-make to control, stability in use is strong, and applicability is good.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 shows a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of gas column control type big orifice stop valve, comprise valve body 1, be arranged on the control valve plate 2 of described valve body 1, the inwall of described valve body is provided with control valve plate and moves cavity 12, be equipped with at the top of the inwall of described valve body 1 and bottom and control horizontal chamber 3, the top of described control valve plate 2 and bottom are equipped with and control protruding 4, described control protruding 4 is arranged in the horizontal chamber 3 of described control, barometric column 5 and Returnning spring 6 is provided with in the horizontal chamber 3 of described control, described barometric column 5 is separately positioned on described Returnning spring 6 both sides controlling protruding 4, and the two ends of Returnning spring 6 are connected to the inwall that controls horizontal chamber 3 respectively and control on protruding 4, the sidewall of described valve body 1 is provided with pressure channel 7, tracheae 8 is provided with in described pressure channel 7, one end of described tracheae 8 and the inlet end of described barometric column 5 seal fixing, source of the gas is provided with outside described valve body 1, described tracheae 8 is connected on source of the gas by control valve 9.
The length of described barometric column 5 is identical with the length in the horizontal chamber of described control 3.
Described tracheae 8 is provided with pneumatic indicator 10.
Rubber spacer 11 is provided with between described control protruding 4 and described barometric column 5.
Its working principle is summarized as follows: in use, open control valve, external air source is made to enter in barometric column by tracheae, because the air pressure entering barometric column increases gradually, therefore barometric column can expand gradually, and then the control projection promoting to control valve plate moves in the horizontal chamber of control, and the spring that gradually reduces, control valve plate is progressed in mobile cavity, realize valve body to open, realize fluid circulation, when needs are closed, give barometric column pressure release gradually, now the reposition force of Returnning spring is greater than the pressure of barometric column, therefore control projection resets gradually under the effect of Returnning spring, and then make control valve sheet reset, complete to disconnect and control.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
