Description
Technical field
The utility model is related to a kind of valves, it particularly relates to a kind of valve with long service life.
Background technology
There are many structures for common valve.Such as：Valve includes valve body, spool, valve rod and wheel disc.Spool is located at valve body
In, the bottom end of valve rod is fixedly connected with spool, and the top of valve rod is fixedly connected with wheel disc.Import and one there are one being set on valve body
Outlet.By rotation roulette, valve rod drives valve core rotation.The rotation of spool realizes unlatching and the closure of valve, and then realizes
Fluid prevents its flowing by valved flow or by valve.No matter valve opening or closing, the flow pressure in water inlet
Power exists always.The hydraulic pressure exerts a force to spool, and valve rod certainly will be made to bear the pressure.In this way, over time will be so that valve rod meeting
Flexural deformation.Once valve rod flexural deformation will make the twisting of valve rod become difficult, valve can not use.
Invention content
Technical problem：The utility model embodiment provides a kind of valve with long service life so that valve rod uniform force, no
It is yielding, to extend the service life of valve.
Technical solution：In order to solve the above technical problems, the present embodiment provides a kind of valve with long service life, including valve
Body, spool and valve rod, spool are located in valve body, and one end of valve rod is fixedly connected with spool, and the other end of valve rod is pierced by valve body, and
It is threadedly coupled between valve rod and valve body；It being set on the body wall there are two opposite water inlet, valve body bottom surface is equipped with water outlet,
The spool includes the first core and the second core, and the first core bottom surface is fixedly connected with the second core top, the first core top
End is fixedly connected with valve rod；The bottom surface of second core is opposite with water outlet；The both sides of first core are opposite with water inlet.
As preference, first core both sides are respectively equipped with rubber seal, and second core bottom surface is equipped with rubber
Glue sealing ring.
As preference, described two water inlets are coaxial, and diameter is identical.
As preference, the bottom end of second core is equipped with rubber boss, and the rubber boss is adapted to water outlet.
Advantageous effect：Compared with prior art, the valve of the present embodiment makes valve rod uniform force, is unlikely to deform, to
Extend the service life of valve.Water inlet there are two being set in the valve of the present embodiment, on body wall, and two water inlets are opposite
Setting.In this way, the pressure direction that the water in water inlet pipe applies spool by water inlet is opposite.Spool uniform force, it is not variable
Shape, to extend the service life of entire valve.In addition, spool includes the first core and the second core, the first core is used for
It is adapted to two water inlets, the second core is used for and water outlet adaptation.By the way that the first core and the second core is arranged, use double
Resealing that is, to inlet seal, and seals water outlet so that the favorable sealing property of entire valve prevents from leaking.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the structural schematic diagram of spool in the utility model embodiment.
Have in figure：Valve body 1, spool 2, valve rod 3, water inlet 101, water outlet 102, the first core 201, the second core 202,
Rubber boss 2021.
Specific implementation mode
Below in conjunction with the accompanying drawings, embodiment is described in detail.
As shown in Figure 1, a kind of valve with long service life of the present embodiment, including valve body 1, spool 2 and valve rod 3.Spool 2
In valve body 1, one end of valve rod 3 is fixedly connected with spool 2, and the other end of valve rod 3 is pierced by valve body 1, and valve rod 3 and valve body 1
Between be threadedly coupled.It is set on 1 side wall of valve body there are two opposite water inlet 101,1 bottom surface of valve body is equipped with water outlet 102.Spool 2
Including the first core 201 and the second core 202,201 bottom surface of the first core is fixedly connected with 202 top of the second core, the first core
201 top of body is fixedly connected with valve rod 3；The bottom surface of second core 202 is opposite with water outlet 102.The both sides of first core 201 with
Water inlet 101 is opposite.
It in the valve of above-described embodiment, is set on 1 side wall of valve body there are two water inlet 101, and two water inlets 101 are opposite sets
It sets.In this way, the pressure direction that the water in water inlet pipe applies spool 2 by water inlet 101 is opposite.2 uniform force of spool, no
It is yielding, to extend the service life of entire valve.As preference, described two water inlets 101 are coaxial, and diameter phase
Together.The pressure size that flow in two such water inlet 101 applies spool 2 is equal, and direction is on the contrary, can offset.In addition,
Spool 2 includes the first core 201 and the second core 202, and the first core 201 is used for and two water inlets 101 are adapted to, the second core
202 with water outlet 102 for being adapted to.By the way that the first core 201 and the second core 202 is arranged, use dual-seal, i.e., into
The mouth of a river 101 seals, and is sealed to water outlet 102 so that the favorable sealing property of entire valve prevents from leaking.
As preference, 201 both sides of the first core are respectively equipped with rubber seal, 202 bottom surface of the second core
Equipped with rubber seal.In order to reinforce sealing effect, 201 both sides of the first core are respectively equipped with rubber seal, described
Second core, 202 bottom surface is equipped with rubber seal.
As preference, as shown in Fig. 2, the bottom end of second core 202 is equipped with rubber boss 2021, the rubber convex
Platform 2021 is adapted to water outlet 102.When closing valve, pass through rotary valve rod 3 so that the rubber convex of 202 bottom end of the second core
Platform 2021 screws in water outlet 102.This can reinforce the sealing effect to water outlet 102.Even if two water inlets 101 ooze
Leakage, water outlet 102 can also be sealed, prevent from leaking by rubber boss 2021.
The basic principles and main features and advantage of the utility model have been shown and described above.Those skilled in the art
It should be appreciated that the utility model is not limited by above-mentioned specific embodiment, the description in above-mentioned specific embodiment and specification is only
