Description
Technical field
The present invention relates to a kind of valves playing cushioning effect by structure of avoiding the peak hour, and belong to valve field.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief.For the valve of fluid control systems, from simplest shut-off valve to extremely complex robot control system(RCS)
Used in various valves, kind and specification are quite various.
Valve can be used for controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Valve is also divided into cast iron valve, cast steel valve, stainless valve according to material（201、
304,316 etc.）, chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
It is entitled " valve " application No. is 201510229504.5, including valve body, the valve body include water inlet
And water outlet, the valve body are made of two cavitys, with water outlet cooperation be the first cavity, with water inlet cooperation
It is the second cavity, the liquid size of water outlet is controlled by the movable push bar component above it by the through flow hole on valve body, institute
Elastic sealing gasket is increased above the plunger for the movable push bar component bottom stated, the diameter of the elastic sealing gasket, which is more than, to be led to
The aperture of discharge orifice.
Above-mentioned valve mechanism is present most common one kind, although simple in structure, once spool breaks down, valve
The open and close of door will be affected, while valve body itself does not have cushioning effect, when liquid or gas flow rate are excessive
When, it is easy to appear failures for valve, influence user's use.
Invention content
The present invention provides a kind of valve playing cushioning effect by structure of avoiding the peak hour and is avoided by the setting of dual spool
When one of spool breaks down the case where valve complete failure, while self by structure setting of avoiding the peak hour, playing slow
Punching acts on.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of valve playing cushioning effect by structure of avoiding the peak hour, including valve body, valve body symmetrically open up on the side wall of bottom
Body cavity is divided into symmetrical two cavitys in valve body by air inlet and gas outlet by separating column, respectively the first cavity and
Second cavity, air inlet are located at the first chamber portion, and gas outlet is located at the second chamber portion；First valve is installed in the first cavity
Core installs the second spool in the second cavity, and the first spool and the second spool size are identical, and the height of valve body is the first valve
Twice of core, the second spool height；
It is fixedly connected with the first valve rod at the top of the first spool, the second valve rod is fixedly connected at the top of the second spool；
Two the first straight slots are opened up in first spool, and two the second straight slots, the first straight slot and the second straight slot are opened up in the second spool
It is opened up with the central axis of valve body, and the location matches of the first straight slot and the second straight slot open up；
Through-hole is equally opened up close to the part of valve body in partition column, position is placed in valve body simultaneously with the first spool, the second spool
The first straight slot, the second straight slot position when bottom match；
As present invention further optimization, the first push-and-pull block is fixed in the end that valve body is stretched out in the first valve rod, and the second valve rod is stretched
The second push-and-pull block is fixed in the end for going out valve body；
As present invention further optimization, inlet channel is connected at air inlet, outlet passageway is connected at gas outlet；
As present invention further optimization, air inlet open height above-mentioned and the first spool height match, outlet open height with
Second spool height matches；
As present invention further optimization, on the top of valve body, flange is laid in installation.
By above technical scheme, compared with the existing technology, the invention has the advantages that：
The present invention has no effect on valve by the setting of the first spool, the second spool when one of spool breaks down
It uses, plays a protective role；
By the setting of avoiding the peak hour of the first spool, the second spool, realizes the change of flow velocity in valve, play cushioning effect.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the overall structure diagram of the preferred embodiment of the present invention.
In figure：1 is the first cavity, and 2 be the second cavity, and 3 be the first valve rod, and 4 be the second valve rod, and 5 be the first straight slot, and 6 are
Second straight slot, 7 be partition column.
Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, the present invention includes following characteristics component：1 is the first cavity, and 2 be the second cavity, and 3 be the first valve rod,
4 be the second valve rod, and 5 be the first straight slot, and 6 be the second straight slot, and 7 be partition column.
A kind of valve playing cushioning effect by structure of avoiding the peak hour of the present invention, including valve body, side of the valve body close to bottom
Air inlet and gas outlet are symmetrically opened up on wall, valve body is interior to be divided into symmetrical two cavitys by separating column by body cavity, respectively
For the first cavity and the second cavity, air inlet is located at the first chamber portion, and gas outlet is located at the second chamber portion；In the first cavity
The first spool of interior installation installs the second spool in the second cavity, and the first spool and the second spool size are identical, and the height of valve body
Degree be the first spool, twice of the second spool height；
It is fixedly connected with the first valve rod at the top of the first spool, the second valve rod is fixedly connected at the top of the second spool；
Two the first straight slots are opened up in first spool, and two the second straight slots, the first straight slot and the second straight slot are opened up in the second spool
It is opened up with the central axis of valve body, and the location matches of the first straight slot and the second straight slot open up；
Through-hole is equally opened up close to the part of valve body in partition column, position is placed in valve body simultaneously with the first spool, the second spool
The first straight slot, the second straight slot position when bottom match；
As present invention further optimization, the first push-and-pull block is fixed in the end that valve body is stretched out in the first valve rod, and the second valve rod is stretched
