Abstract
The invention provides a spool of a cut-off valve, belonging to the mechanical technical field. The invention solves the problems that the spool is tilted during movement and the application stability of the cut-off valve is affected because a traditional cut-off valve spool is directly installed on a valve body. The spool of the cut-off valve comprises a connecting rod and a water pressing plate, wherein the water pressing plate is fixedly connected at the end part of the connecting rod. The spool of the cut-off valve additionally comprises a cylindrical connecting seat and a pressing cap, wherein the connecting seat is connected with the valve body and the pressing cap is connected on the internal side of the connecting seat. A guide structure which can enable the connecting rod to horizontally move relative to the connecting seat is arranged between the pressing cap and the internal side of the connecting seat. Since a guide cylinder and a spring are used for guiding the movement of the connecting rod, the invention has the advantages that the water pressing plate is enabled to move stably and horizontally and the application stability of the cut-off valve with the spool is improved.

Background technique
The open-shut device of stop valve is a spool, and the moving direction and the flow direction of spool are perpendicular.The spool that is to say stop valve is vertically to move back and forth in course of action.
Existing stop valve usually by valve body be connected with valve body in spool form, the in use above-mentioned spool of stop valve moves up and down with respect to the flowing medium Vertical direction in valve body.Spool directly is contained on the valve body, deflection possibly occur in the spool moving process.Can find out, can not open completely or close stop valve after the spool deflection, influence its stability in use.
Summary of the invention
The objective of the invention is the problems referred to above, the stop valve spool that a kind of stability is high, sealing is high is provided to the existing technology existence.
The object of the invention can be realized through following technical proposal: a kind of spool of stop valve; Comprise a connecting rod and the setting-out plate that is connected in interlinking lever end; It is characterized in that; It comprises also and is used for linking to each other and tubular connecting base and pressure cap with valve body that pressure cap is connected in the connecting base inboard, and between pressure cap and connecting base inboard, has and can make the guide structure of connecting rod with respect to the connecting base translation.
This spool is installed in the valve body of stop valve.Stop valve connecting rod in the switching process drives the setting-out plate and moves.Under the effect of guide structure, make and the translation that connecting rod can be stable make stop valve have than higher stability in use with this spool.
In the spool of above-mentioned stop valve, described guide structure is to be located at connecting base inboard guide cylinder and spring, and guide cylinder endoporus and above-mentioned connecting rod size are complementary and guide cylinder is enclosed within on the connecting rod, and the two ends of spring act on respectively on guide cylinder and the connecting base.
Guide cylinder has on the pressure cap of being resisted against all the time under the elastic force effect of spring, and obviously, guide cylinder keeps its axis parallel with pressure cap all the time under the elastic force effect of spring.And guide cylinder is enclosed within on the connecting rod, so just makes connecting rod keep the translation state.
In the spool of above-mentioned stop valve, described pressure cap is connected through screw thread with connecting base.
Through being threaded pressure cap is connected easily with connecting base, its connectivity robustness is than higher simultaneously.
In the spool of above-mentioned stop valve, said pressure cap is cylindric, and the pressure cap lower outside has annular chamfer one, and above-mentioned connecting base inboard has the annular retaining edge that is complementary with annular chamfer.
Annular chamfer and annular retaining along cooperate make pressure cap and connecting base to be connected precision high, and connection procedure is stablized.
In the spool of above-mentioned stop valve, described connecting base inboard has step-like shoulder block one, and said connecting base inboard also is fixed with pad one, and above-mentioned connecting rod passes pad one, is provided with seal washer one between pad one and the shoulder block one.
Through pad one and shoulder block one that seal washer one is spacing, the joint through sealing packing ring pair of links and connecting base seals in the connecting rod moving process simultaneously.
In the spool of above-mentioned stop valve, the spacing between said pad one and the shoulder block one is greater than the thickness of seal washer one.
Seal washer one that is to say each position and the connecting rod contact friction of seal washer one along with together moving in the connecting rod moving process, has avoided seal washer one local friction and premature damage.
In the spool of above-mentioned stop valve, described pressure cap inboard has step-like shoulder block two, and said pressure cap inboard also is fixed with pad two, and above-mentioned connecting rod passes pad two and pressure cap, is provided with seal washer two between pad two and the shoulder block two.
Through pad two and shoulder block two that seal washer two is spacing, the joint through two pairs of connecting rods of sealing packing ring and pressure cap seals in the connecting rod moving process simultaneously.
In the spool of above-mentioned stop valve, the spacing between said pad two and the shoulder block two is greater than the thickness of seal washer two.
Seal washer two that is to say each position and the connecting rod contact friction of seal washer two along with together moving in the connecting rod moving process, has avoided seal washer two local frictions and premature damage.
In the spool of above-mentioned stop valve, the described connecting base outside has screw thread.
The valve body inboard has internal thread, and connecting base can make whole spool be connected on the valve body easily with valve body through being threaded.
In the spool of above-mentioned stop valve, described connecting base inboard has and the corresponding shoulder block three of setting-out Board position.The setting-out plate is positioned at the bottom of shoulder block three during original state, when connecting rod drive move on the setting-out plate after, the setting-out plate receives shoulder block three to be stopped and moves on can't continuing.
Compared with prior art, the spool of this stop valve can lead to the mobile of connecting rod through guide cylinder and spring, thereby makes the translation that the setting-out plate can be stable.Improved the stability in use of stop valve with this spool.
Simultaneously; Seal washer one all has mobile space with seal washer two in this spool; The various piece of seal washer one, two obtains friction in the using process, has effectively avoided the excessive problem of concentrated wear amount, has improved the stability in use and the life-span of whole spool.And, through seal washer one and seal washer two sealing of whole valve core inside is improved.
