Abstract
A ball valve seat is fixed on a valve body. A valve spool is arranged inside the seat, the inner wall of the seat clings to the valve spool, at least one circle of groove is arranged at the clinging joint of the inner wall of the seat and the valve spool, and a boss is arranged at the joint of the back surface of the seat and the valve body. As contact area between the valve spool and the valve body is reduced, prestress is concentrated effectively, sealing property is guaranteed while sealing action is reduced and service cost is reduced. Simultaneously, switching torque of the valve is reduced, thereby bringing convenience to switching of the valve.
Description
Technical field
The utility model relates to a kind of valve seat, is specifically related to a kind of ball seat.
Background technique
Ball valve is used in all trades and professions widely with its excellent sealing performance and negotiability, and as the valve seat of one of vitals of ball valve, the quality of its performance seriously influences the sealing of ball valve.
Existing ball seat is fixed on the valve body, and valve base inner wall and spool are fitted closely, guarantees the area of contact of valve seat and valve core chamber, improves the sealing of valve.But because existing valve seat is bigger with the area of contact of spool, the pretightening force that makes valve body put on the valve seat is disperseed, and impacting force that need be bigger is to the valve body sealing of exerting pressure, and leakage efficiency is lower; Simultaneously, area of contact is bigger, can increase the friction of valve seat and valve core chamber, opening or moment during throttle down increases, to transmission device performance requirement improve, increase user cost.
In addition, because existing valve seat is directly fixed on the valve body, dismounting is effort.
Therefore, a kind of leakage efficiency is higher, and user cost is lower and dismantle more convenient valve seat and demand urgently occurring.
The model utility content
Bigger for solving existing valve seat and valve core chamber area of contact, cause pretightening force to strengthen, problems such as user cost increase the utility model discloses a kind of ball seat, to reach the raising leakage efficiency, reduce the purpose of user cost.
The technical solution of the utility model is as follows:
A kind of ball seat, be fixed on the valve body, described valve seat inside is provided with spool, and the inwall of described valve seat and described spool fit, the inwall of described valve seat and described spool joint place are provided with at least one circle groove, and the back side of described valve seat and described valve body joint are provided with boss.
Preferably, described groove is two circles.
Preferably, described valve seat is provided with at least 2 and makes described valve seat be convenient to adorn the groove of getting.
The disclosed ball seat of the utility model by at valve seat and spool position contacting groove being set, reduces the area of contact of valve seat and valve core chamber; Simultaneously, boss is set, reduces the area of contact of valve body and valve base chamber, form higher seal pressure, guarantee to adopt littler pretightening force to realize more effectively sealing effect at valve seat and valve body connection; Reduce the frictional force of valve seat and valve core chamber simultaneously, made the moment of valve opening and closing reduce, reduced user cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the plan view of the disclosed a kind of ball seat of the utility model;
Fig. 2 looks sectional view for the disclosed a kind of ball seat of a utility model left side;
Fig. 3 is the sectional view of the ball valve of the disclosed valve seat of use the utility model.
The title of the corresponding part that numeral among the figure or letter are represented:
11, valve seat 12, groove 21, groove 22, boss 23, inwall 31, valve body 32, spool
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of ball seat, groove is set and boss is set, reduce the area of contact of valve seat and valve body and valve core chamber, reduce user cost at valve seat and valve body joint by contacting point at valve seat and spool.
As Figure 1-3, valve seat 11 is fixed on the valve body 31, and valve seat 11 inside are provided with spool 32, and the inwall 23 and the spool 32 of valve seat 11 fit, and the back side of valve seat 11 is fixed in the valve body 31.
The inwall 23 of valve seat 11 is provided with groove 21, the setting of groove 21 has reduced the area of contact of 32 of valve seat 11 and spools, the back of valve seat 11 and the joint of valve body 31 are provided with boss 22 simultaneously, the setting of boss 22, reduced the area of contact of valve seat 11 with valve body 31, make impacting force more concentrated, when guaranteeing sealing, reduced the pressure of valve seal, also reduced the frictional force of 32 of valve seats 11 and spool in the valve body switching process simultaneously, make open and close torque reduce, be convenient to the switch of valve.
The side of valve seat 11 is provided with groove 12, is convenient to the dress of valve seat 11 is got, and the quantity of groove 12 is at least 2, and symmetrically, in addition, the shape and the size of groove 12 all are determined on a case-by-case basis, and do not do qualification at this.
The disclosed ball seat of the utility model, by groove being set at valve seat and spool position contacting, reduce the area of contact of valve seat and valve core chamber, simultaneously, at valve seat and valve body connection boss is set, reduce the area of contact of valve body and valve base chamber, form higher seal pressure, guarantee to adopt littler pretightening force to realize more effectively sealing effect; Reduce the frictional force of valve seat and valve core chamber simultaneously, made the moment of valve opening and closing reduce, reduced user cost.
More than be description,, make related domain professional and technical personnel can realize or use the utility model by above-mentioned explanation to the disclosed embodiments to the utility model embodiment.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
