Description
Technical field
This utility model relates to valve field, is specifically related to a kind of balanced type break valve.
Background technology
Stop valve is widely used in being the various field such as oil, chemical industry.Its advantage is: simple in construction, manufactures and keep in repair ratio
More convenient.Keying stroke is short, opens and closes the time needed short.Good airproof performance, between sealing surface, frictional force is little, lasts a long time.In opening and closing
During the frictional force of sealing surface less than gate valve, wear-resisting.Generally only one of which sealing surface, manufacturing process is good, it is simple to maintenance.But this
Kind valve is when fluid pressure is big, and during opening and closing, required power is bigger.For solving this problem, occur as soon as pressure
Balanced valve.Existing a lot of pressure balanced stop valve, but this kind of valve all structures are complicated, keep in repair relatively difficult.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of simple in construction,
Effectively solve the balanced type break valve of opening and closing difficult problem.
The purpose of this utility model can be achieved through the following technical solutions: a kind of balanced type break valve, this stop valve
Including valve body, valve gap, spool and handwheel, described valve body includes valve pocket and the lower through-hole connected with valve pocket and upper through hole, described
Spool includes flap, flap set and valve rod, and described flap set is fixed on the top of described valve pocket, and described flap is interior with what flap overlapped
Slideslip connects, and described valve rod one end is connected with flap top, and the other end is connected with handwheel, under described valve gap through described valve gap
Inside side, flap set and the upside of flap forms counter balance pocket, and the upside of described flap has for connecting counter balance pocket and valve pocket
Through hole.
Described through hole is uniformly distributed around valve rod, and the quantity of through hole is 2～8.
Central authorities bottom described flap are provided with cylindrical groove, and the two ends of described through hole connect counter balance pocket respectively and flap is recessed
Groove.
The bottom of described flap is connected with the upper end sidewall contact of described lower through-hole.
Owing to arranging through hole, counter balance pocket is connected with valve pocket, so the pressure between counter balance pocket and valve pocket remains one
Cause, make spool open and close moment the most not by the active force (medium power mutually balances) of medium, it is only necessary to less
Power it is ensured that be turned on and off；And flap uses the form of hollow, the weight of flap itself is the most little, the most effectively
Required power bigger problem when solving to open and close.
Described flap set is equipped with sealing ring with valve body, valve gap and flap junction.This sealing ring uses the elasticity of import
Sealing ring, good sealing effect, life-span length is the most aging, can be according to the pressure automatic-sealed of medium.
Work process of the present utility model is as follows: during original state, the bottom of flap and the upper end sidewall contact of lower through-hole
Connect, lower through-hole is blocked, and due to flap upper groove and the existence of through hole so that the pressure between lower through-hole and counter balance pocket is
The same；It addition, upper through hole is blocked by the lateral wall of flap, whole stop valve is in disconnection state.
When stop valve opened by needs, rotate handwheel, valve rod is up mentioned, thus drives flap to overlap inwall along flap
Moving upward, flap separates with the upper end of lower through-hole, and therefore lower through-hole, valve pocket connect with upper through hole, and fluid flows.This practicality is new
Type stop valve changes the structural shape of current heavy caliber stop valve, makes medium flow to the most restricted, it is possible to achieve two-way close
Envelope, is especially used on oxygen Nitrogen pipe network, and security performance is high and effective.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) arranging through hole makes counter balance pocket connect with valve pocket, so the pressure between counter balance pocket and valve pocket remains one
Cause, make spool open and close moment the most not by the active force (medium power mutually balances) of medium, it is only necessary to less
Power it is ensured that be turned on and off；
(2) change the structural shape of current heavy caliber stop valve, make medium flow to the most restricted, it is possible to achieve two-way
Sealing, be especially used on oxygen Nitrogen pipe network, security performance is high and effective；
(3) sealing ring uses the elastic seal ring of import, and good sealing effect, life-span length is the most aging, can be according to the pressure of medium
Power automatic-sealed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is valve body, and 2 is valve gap, and 3 is handwheel, and 4 is flap set, and 5 is flap, and 6 is valve rod, and 7 is lower through-hole, and 8 are
Upper through hole, 9 is valve pocket, and 10 is counter balance pocket, and 11 is through hole, and 12 is sealing ring.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment is being front with technical solutions of the utility model
Put and implement, give detailed embodiment and concrete operating process, but protection domain of the present utility model does not limits
In following embodiment.
Embodiment
A kind of balanced type break valve, its structure as it is shown in figure 1, this stop valve includes valve body 1, valve gap 2, spool and handwheel 3,
Valve body 1 includes valve pocket 9 and the lower through-hole 7 connected with valve pocket 9 and upper through hole 8, and fluid can enter from lower through-hole 7, through valve pocket 9
Finally flowing out from upper through hole 8, vice versa.Spool includes that flap 5, flap set 4 and valve rod 6, flap set 4 are fixed on valve pocket 9
Top, and the place that flap set 4 and valve pocket 9 connect is provided with sealing ring 12, flap 5 is arranged on the inner side of flap set 4, and and flap
Set 4 is slidably connected, and also is provided with sealing ring 12 between flap 5 and flap set 4；Valve rod 6 one end is connected with flap 5 top, another
End is connected through valve gap 2 with handwheel 3.Wherein the upside of the downside of valve gap 2, the inner side of flap set 4 and flap 5 forms counter balance pocket
10, the central authorities bottom flap 5 are provided with cylindrical groove, have through hole 11 in the upside of flap 5 so that counter balance pocket 10 and flap 5 are recessed
Pressure in groove is equal, so that the pressure of counter balance pocket 10 is identical with valve pocket 9 and lower through-hole 7.
During original state, the bottom of flap 5 is connected with the upper end sidewall contact of lower through-hole 7, is blocked by lower through-hole 7, and by
In flap 5 upper groove and the existence of through hole 11 so that the pressure between lower through-hole 7 and counter balance pocket 10 is the same；It addition, flap
Upper through hole 8 is blocked by the lateral wall of 5, and whole stop valve is in disconnection state.
When stop valve opened by needs, rotate handwheel 3, valve rod 6 is up mentioned, thus drive flap 5 to overlap 4 along flap
Inwall moves upward, and flap 5 separates with the upper end of lower through-hole 7, and therefore lower through-hole 7, valve pocket 9 connect with upper through hole 8, fluid stream
Dynamic.This utility model stop valve changes the structural shape of current heavy caliber stop valve, makes medium flow to the most restricted, permissible
Realizing two way seal, be especially used on oxygen Nitrogen pipe network, security performance is high and effective.
