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, leakproofness cannot ensure, together
When valve body itself do not have cushioning effect, when liquid or excessive gas flow rate, valve influences to use it is easy to appear failure
Person uses.
Invention content
The present invention provides a kind of valve with cushioning effect, under the premise of structure simplify, not only sealing performance
It is good, and included pooling feature, delay the service life of valve.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of valve with cushioning effect, including valve body, internal is hollow structure, right on the side wall close to body base
Title opens up opening, respectively inlet and outlet；
Annular groove, the height of the height and import, outlet of annular groove are circumferentially opened up in side wall of the valve inner close to bottom surface
It is identical；
Further include spool, the height of spool is identical as the height of annular groove, and the both ends of spool are stuck in annular groove, in spool
Portion opens up a plurality of straight slot, and straight slot is opened up with valve body central axis；
Valve rod is fixed in the center of spool, and one end of valve rod is connect with spool, and the other end stretches out valve body；
As present invention further optimization, in the top mounting flange of valve body；
As present invention further optimization, at the top of valve rod, the fixed spill spin block of installation, opens up in body top for interting
The rotating hole of valve rod lays the first screw thread on rotating hole inner wall, second is laid on the circumferential surface that valve rod is contacted with rotating hole
Screw thread, the first screw thread match with the second screw thread；
As present invention further optimization, two straight slots are opened up in spool, the two is mutually parallel laying；
As present invention further optimization, intake channel is set in the entrance of valve body, exit passageway is arranged in exit.
By above technical scheme, compared with the existing technology, the invention has the advantages that：
The both ends of spool are stuck in annular groove by the present invention, only need to move position of the spool in annular groove, you can realize valve body
Closing and unlatching；
A plurality of straight slot is opened up in valve core inside, straight slot is opened up with valve body central axis, when the direction of straight slot and import, outlet exist
When on same straight line, valve body, which is realized, to be opened, and is converted with the position of spool, and straight slot generates angle, convection current with import, export direction
Speed plays the role of cushioning control.
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 valve body, and 2 be spool, and 3 be valve rod, and 4 be spill spin block, and 5 be straight slot.
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 valve body, and 2 be spool, and 3 be valve rod, and 4 be spill spin block, 5
For straight slot.
A kind of valve with cushioning effect of the present invention, including valve body, internal is hollow structure, close to valve body bottom
Opening, respectively inlet and outlet are symmetrically opened up on the side wall in portion；
Annular groove, the height of the height and import, outlet of annular groove are circumferentially opened up in side wall of the valve inner close to bottom surface
It is identical；
Further include spool, the height of spool is identical as the height of annular groove, and the both ends of spool are stuck in annular groove, in spool
Portion opens up a plurality of straight slot, and straight slot is opened up with valve body central axis；
Valve rod is fixed in the center of spool, and one end of valve rod is connect with spool, and the other end stretches out valve body；
As present invention further optimization, in the top mounting flange of valve body；
As present invention further optimization, at the top of valve rod, the fixed spill spin block of installation, opens up in body top for interting
