Abstract

The utility model discloses a kind of slide valve, including valve body, flashboard, valve rod, bonnet, operating mechanism, bonnet is located in valve body, stem lower portion is connected through bonnet with flashboard, valve rod top is connected with operating mechanism, Buffer Unit is provided with the surface that flashboard contacts with medium, Buffer Unit includes contact plate and the spring being installed between contact plate and flashboard.Using Buffer Unit come the impulsive force of buffer medium, circulation medium Contact -impact plate, spring-compressed is simultaneously compressed to resilience after the limit, contact plate promotion medium is flowed toward opposite direction, and the impulsive force of a part is counteracted after the media impingement in two bursts of opposite directions, reduces influence of the impulsive force of medium moment to flashboard, good buffer effect, the destroyed hidden danger of sealing is avoided, is installed additional on script flashboard, cost is relatively low.

Description

Slide valve

Technical field

It the utility model is related to valve field, and in particular to a kind of slide valve.

Background technology

Slide valve is also referred to as gate valve, is primarily adapted for use in and is switched off or on pipeline medium.The valve rod of slide valve promotes flashboard to block Into the medium in valve flowing channel, and when medium is flowed into valve flowing channel, directly connect with the flashboard under being closed Touch, when having the big flow velocity of certain impulsive force, especially rate-of flow fast to flashboard, larger instant impact can be produced, This is likely to result in flashboard vibration, so as to destroy the sealing of script between flashboard and valve body.

The content of the invention

The purpose of this utility model：The defects of in order to overcome prior art, the utility model provide one kind and can buffered The slide valve of media impingement power.

The technical solution of the utility model：Including valve body, flashboard, valve rod, bonnet, operating mechanism, bonnet is located in valve body, Stem lower portion is connected through bonnet with flashboard, and valve rod top is connected with operating mechanism, is set on the surface that flashboard contacts with medium There is Buffer Unit, Buffer Unit includes contact plate and the spring being installed between contact plate and flashboard.

Using above-mentioned technical proposal, using Buffer Unit come the impulsive force of buffer medium, circulation medium Contact -impact plate, bullet Spring compresses and is compressed to resilience after the limit, and contact plate promotion medium flows toward opposite direction, after the media impingement in two bursts of opposite directions The impulsive force of a part is counteracted, reduces influence of the impulsive force of medium moment to flashboard, good buffer effect, avoids sealing Destroyed hidden danger, is installed additional on script flashboard, and cost is relatively low.

It is of the present utility model further to set：The mounting hole coordinated with Buffer Unit, the contact plate are offered on flashboard Slide and coordinate with mounting hole, the spring is arranged between mounting hole bottom and contact plate.

Further set using above-mentioned, it is the main stress surface being hit to make contact plate, and mounting hole ensures Buffer Unit not The power that is easily hit influences and damaged, and ensure that the integrality of Buffer Unit.

It is of the present utility model further to set：The surface that contact plate contacts side with medium is in sunken inside shape.

Further set using above-mentioned, stress is more concentrated, and contact plate is remained perpendicular to flow of media side as far as possible To sliding.

Setting further again of the present utility model：It is additionally provided with the surface that flashboard contacts with medium and is contacted for limitation The locating part that plate is deviate from by mounting hole.

Using above-mentioned setting further again, Buffer Unit is set to be worked all the time in mounting hole, that improves Buffer Unit can By property.

Setting further again of the present utility model：Locating part includes catch, screw and the cunning being arranged on flashboard Groove, the catch is inconsistent with contact plate with merging with chute sliding, and the screw is installed on relative catch toward the mounting hole center of circle In the chute in the reverse direction of glide direction.

Using above-mentioned setting further again, catch is used for spacing contact plate, and chute is used to slide catch, screw when dismounting Catch is limited in the state of conflict contact plate, it is ensured that catch is not slided in chute by media impingement, and dismounting is very convenient.

Setting further again of the present utility model：Locating part is arranged to four, the flashboard being distributed at mounting hole aperture On.

Using above-mentioned setting further again, four locating parts being evenly arranged can be effectively by Buffer Unit and mounting hole It is interior.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model specific embodiment；

Fig. 2 is the sectional view of the utility model flashboard；

Fig. 3 is the structural representation of the utility model flashboard；

Wherein, valve body 1, flashboard 2, valve rod 3, bonnet 4, operating mechanism 5, Buffer Unit 6, contact plate 61, spring 62, installation Hole 21, locating part 7, catch 71, screw 72, chute 73, runner 8.

Embodiment

Slide valve as Figure 1-3, including valve body 1, flashboard 2, valve rod 3, bonnet 4, operating mechanism 5, bonnet 4 are located at valve In body 1, the bottom of valve rod 3 is connected through bonnet 4 with flashboard 2, and the top of valve rod 3 is connected with operating mechanism 5, and flashboard 2 contacts with medium Surface on be provided with Buffer Unit 6, Buffer Unit 6 includes contact plate 61 and is installed between contact plate 61 and flashboard 2 Spring 62, the mounting hole 21 coordinated with Buffer Unit 6 is offered on flashboard 2, the contact plate 61 slides with mounting hole 21 matches somebody with somebody Close, the spring 62 is arranged between the bottom of mounting hole 21 and contact plate 61.When medium is poured in runner 8, media impingement buffering group Contact plate 61 in part 6, the stress of contact plate 61 slide backward, and compression spring 62, spring 62 rebounds after being compressed to the limit, promotes The promotion medium of contact plate 61 flows toward opposite direction, and two strands of media are then toward the impact in opposite direction, so as to counteract a part of medium Impact.

The surface that contact plate 61 contacts side with medium is in sunken inside shape, and sunken inside shape is the surface home position of contact plate 61 With the depth relative to circumferential position, the inner concavity of contact plate 61 close to home position is showed.

The locating part deviate from for limiting contact plate 61 by mounting hole 21 is additionally provided with the surface that flashboard 2 contacts with medium 7, locating part 7 includes catch 71, screw 72 and the chute 73 being arranged on flashboard 2, and the catch 71 slides with chute 73 Inconsistent with contact plate 61 with merging, the screw 72 is installed on relative catch 71 toward the negative side of the center of circle glide direction of mounting hole 21 In upward chute 73, locating part 7 is arranged to four, is distributed on the flashboard 2 at the aperture of mounting hole 21.Locating part 7, which props up, to be connect Buffer Unit 6 is limited in mounting hole 21 by touch panel 61, skids off catch 71 in chute 73, and catch 71 contradicts contact plate 61, Screwing 72 is installed, and makes the top surface of screw 72 it is not slided so as to prop up catch 71 higher than the bottom surface of catch 71.
