Description
Technical field:
The present invention relates to regulating valve, in particular to the regulating valve of a kind of good antiscale property and low friction resistance.
Background technique:
The choosing of the material of the general valve body 91 of straight stroke electric regulating valve used in the water systems such as air-conditioning and heat supply field and valve deck 92
Cylinder iron part, as shown in Figure 1, part such as spool 93, valve seat, valve rod 94 etc. selects 304 stainless steels in valve, and based at we
The considerations of face most of this type the not individually designed sleeve of valve, valve deck 92 directly contacts with spool 93, and spool 93 is in valve
Closing, the flow adjusting etc. for completing valve with respect to sliding with about 92 valve deck under the drive of bar 94 act.Due to the material of valve deck 92
Matter generally selects ironcasting that can not accomplish good preservative treatment, and result caused in this way is often that valve uses a period of time
Afterwards, the contact surface of valve deck 92 and spool 93 causes valve rod 94 because the effect of medium (water or vapor) can generate corrosion and scaling
Closing forces incrementally increase, phenomena such as 94 appearance of valve rod movement creeps, is sluggish, valve rod 94 can not act when serious, and valve can not
It uses.In order to solve problems, most producers mostly use greatly increase tube-in-tube structure or by the material of valve deck be changed to cast copper or
Stainless steel is cast, the manufacturing cost of valve is virtually increased in this way, reduces the competitiveness of product in market.
Summary of the invention:
In consideration of it, it is necessary to design a kind of simple structure, at low cost and good antiscale property and the regulating valve of low friction resistance.
The regulating valve of a kind of good antiscale property and low friction resistance, comprising: valve deck, valve body, valve rod, spool, copper is bushing, valve seat；
Wherein, valve deck is fixed on body top, and valve rod passes through valve deck and is fixedly connected with the spool in valve body cavity, and spool shaft section is
Spool is divided into upper and lower two cavitys, passes through the mistake on partition between upper and lower two cavitys by " H " shape, the partition in the middle part of spool
Water hole connection, valve body cavity middle and lower part are fixed with valve seat, and spool lower half is opened upwardly down through valve seat, valve deck opposite direction spool
There is one week groove, copper is bushing to be cylindric, and the bushing setting of copper is in the groove and the bushing inner wall of copper passes through interference fit and valve
Lid is fixed, and another side wall of the spool top insertion bushing outside cylinder wall surface of copper and the groove is formed by groove.
Preferably, interior on valve deck to be additionally provided with extension spring, extension spring covers outside valve rod, cavity bottom locating for extension spring
Portion passes through packing seal by sealing ring and valve stem seal, extension spring top.
The present invention merely adds the very thin copper edge of wall thickness under the premise of possessing valve deck ontology cast iron quality (at low cost)
Set, reduces the cost of valve deck；Since copper material has good ductility, it is ensured that the reliability of high temperature hot-mounting process, work
Skill is simple and reliable, at low cost；Copper has preferable corrosion resistance in water or vapor, will not go out in later use process
Existing scale formation, it is ensured that the reliability service of valve actuator.
Detailed description of the invention:
Attached drawing 1 is the partial schematic sectional view of the regulating valve of a width prior art.
Attached drawing 2 is the partial schematic sectional view of width good antiscale property of the invention and the regulating valve of low friction resistance.
In figure:
The prior art: valve body 91, valve deck 92, spool 93, valve rod 94；
The present invention: valve deck 1, valve body 2, valve rod 3, spool 4, copper is bushing 5, valve seat 6, partition 41, water hole 42, groove 11,
Sealing ring 51, extension spring 7.
Specific embodiment:
As shown in Fig. 2, the regulating valve of a kind of good antiscale property and low friction resistance, by the way of upper entering and lower leaving, comprising: valve deck
1, valve body 2, valve rod 3, spool 4, copper is bushing 5, valve seat 6；Wherein, valve deck 1 is fixed on 2 top of valve body, and valve rod 3 passes through valve deck 1 simultaneously
It is fixedly connected with the spool 4 in valve body cavity, 4 shaft section of spool is " H " shape, and spool 4 is divided by the partition 41 at 4 middle part of spool
Upper and lower two cavitys, by 42 connection of water hole on partition 41 between upper and lower two cavitys, valve body cavity middle and lower part is fixed with
Valve seat 6,4 lower half of spool are provided with one week groove 11 upwardly down through valve seat 6, the opposite spool 4 of valve deck 1, and copper bushing 5 is
Cylindrical shape, copper bushing 5 is arranged in the groove 11 and bushing 5 inner wall of copper is fixed with valve deck 1 by interference fit, on spool 4
Another side wall of portion's insertion bushing 5 outside cylinder wall surface of copper and the groove 11 is formed by groove.Valve deck 1 and valve body 2 and
It can be sealed by sealing ring between valve seat 6 and valve body 2.Bushing 5 lower end outside of copper is sealed by sealing ring 51 and spool 4.
In the present embodiment, on valve deck 1 in be additionally provided with extension spring 7,7 sets of extension spring outside valve rod 3, extension spring
Cavity bottom locating for 7 is sealed by sealing ring and valve rod 3, passes through packing seal at the top of extension spring 7.
