Description
Technical field
The utility model relates to a kind of valve, in particular to the noise reduction ball valve of a kind of stable structure.
Background technique
Ball valve is widely used in petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel
The industries such as iron occupy very important status in national economy.It has the movement being rotated by 90 °, and faucet body is sphere, is had
Circular through hole or channel pass through its axis.
Existing ball valve mainly includes valve body, valve seat, sphere and valve rod, and sphere is set to body cavity, and valve seat is set to
Body cavity and cooperation sphere realization shut off for the sealing of medium, sphere then by valve rod drive and around valve rod circumferentially make 90 degree revolve
Transhipment is dynamic, to realize the open and close function of valve.But existing valve seat is all to be inlaid in valve inner, if valve seat
With valve body since mismachining tolerance causes fit tolerance between the two excessive and valve is again just at opening during production
When opening state, the medium of ball valve inlet side then can push valve seat direction by the fit-up gap formed between valve seat and valve body surface
Sphere direction is mobile, especially the medium of high-voltage high-speed, can separate with valve body so as to cause the excessive part valve seat of tolerance,
Ball valve is eventually led to leak.
Utility model content
The purpose of the utility model is to provide a kind of noise reduction ball valve of stable structure, the noise reduction ball valve of the stable structure possesses
More stable mounting structure, prevents valve seat from separating with valve body, so that ball valve does not leak.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of drop of stable structure
It makes an uproar ball valve, including valve body, is set to the runner of valve body and is installed on the valve deck of valve body, be equipped with and worn into valve on the valve deck
The valve rod in internal portion, one end that the valve rod is located at valve inner are equipped with the sphere rotated with valve rod, and the valve inner is set
There is mounting groove, the valve seat that cooperation sphere realizes sealing is equipped in the mounting groove, the installation trench bottom offers cross sectional shape
For the slide opening of rectangle, the center of circle of the slide opening around valve seat is provided at least two, and the valve seat periphery wall corresponds to slide opening
Position be equipped with jack, sliding is provided with adaptation therewith in the slide opening and length is greater than the bar shaped inserted block of jack depth, described
Valve interior wall is equipped with the company hole of connection slide opening, and the inserted block, which is equipped with back to one end of valve seat towards inclined first inclination in even hole, to be drawn
Guide face, the even hole internal screw thread are connected with actuator, and the actuator is equipped with the first inclined lead of cooperation towards one end of slide opening
Face simultaneously drives inserted block to plug the second angular guide surfaces into jack, when first angular guide surfaces are supported with the second angular guide surfaces
When tight, the inserted block is plugged into jack.
By using above-mentioned technical proposal, it is first inserted into inserted block in slide opening before valve seat is installed, then valve seat is installed into
Mounting groove simultaneously keeps jack corresponding with slide opening；Actuator is threadedly coupled to drive the second inclined lead facing towards slide opening with even hole
Direction is mobile, and when the second angular guide surfaces offset with the first angular guide surfaces, the mode of offseting between the two changes power
Direction of transfer, so that the mobile of actuator can drive inserted block to slide and plug into jack towards jack direction in slide opening.It is logical
It crosses inserted block to limit the valve seat being installed in mounting groove, so that the mounting structure of valve seat is more stable, prevents valve seat and valve
Body separates, so that ball valve does not leak.
Be further arranged to: the valve seat back to sphere an end face and mounting groove side wall between be formed with gap, institute
The draining ring that flow path wall Yu valve seat internal perisporium are equipped with while fitted in runner is stated, the draining ring periphery wall, which is installed with, to be extended into
The positioning convex ring in gap, the positioning convex ring outer wall are equipped with while being bonded the sealing ring of valve seat and mounting groove.
By using above-mentioned technical proposal, the setting of draining ring plays drainage to medium, so that the medium in flowing
The position between valve seat and mounting groove will not be caused to wash away；And the sealing ring for fitting in valve seat and mounting groove simultaneously can be real simultaneously
Existing sealing between positioning convex ring, valve seat and mounting groove three reduces medium and enters inside valve seat and mounting groove, to reach
Better seal effect, prevents leakage.
Be further arranged to: the flow path wall is located at draining ring and is installed with guide ring relative to the other side of valve seat, described
Guide ring offsets towards an end face of draining ring and draining ring and width is equal to draining ring end face width.
By using above-mentioned technical proposal, the setting of guide ring reduces fluid and washes away for caused by draining ring end face, and
Fluid can be further decreased and entered in gap and wash away dynamics, the sealing ring of setting is enabled to reach better seal effect,
And realize the purpose of noise reduction.
Be further arranged to: the valve seat internal perisporium is installed with baffle ring close to the position that offsets of valve seat and sphere, described
The material of baffle ring is wear-resistant material.
By using above-mentioned technical proposal, the setting of baffle ring reduces direct punching of the fluid for sealing surface of seat in fluid
Brush, enables ball valve to reach better seal effect.
Be further arranged to: the baffle ring back to sphere an end face and baffle ring internal perisporium between be equipped be tilted over
The inclined-plane of degree.
By using above-mentioned technical proposal, the setting on inclined-plane plays guiding function to fluid, reduces fluid and is washing away baffle
The noise generated when ring, achievees the purpose that noise reduction.
In conclusion the utility model has the following beneficial effects: the structure of the utility model is more stable, leakproofness more
Well and there is decrease of noise functions.
