Abstract
The utility model discloses a fixed ball valve base, which comprises a valve base body. One surface of the valve base body is adhered with a valve ball to form a sealing surface, the other surface of the valve base body is sealed with a valve cover, an adjusting spring is disposed between the valve base body and the valve cover, the adjusting spring is arranged inside a groove of the valve cover, two ends of the adjusting spring are respectively abutted to the valve base body and the valve cover, one side of the valve base body close to fluid medium extends towards the valve cover to form a step, a platform is formed above the step through the valve cover extending towards the valve base body, the step and the platform are in parallel arrangement, and a certain gap with a distance ranging from 0.1mm to 1.5mm is arranged between the step and the platform. The fixing ball valve base with extremely simple structure saves production cost, improves work efficiency, prevents particle media from entering a working area of the spring by simultaneously employing the step formed by the valve base extending towards the valve cover and the platform formed by the valve cover extending towards the valve base, reduces corrosion caused by the particles to the adjusting spring, effectively protects the adjusting spring and prolongs the service life of the adjusting spring.
Description
Technical field
The utility model relates to a kind of valve seat of valve, especially relates to a kind of valve seat that is applied on the fixing ball valve.
Background technique
Fixing ball valve is mainly used in every field such as oil, chemical industry, iron and steel, metallurgy and electric power, and with respect to the valve of other controlling plumbing fixtures medium circulations, fixing ball valve has advantages such as resistance of medium is little, easy to operate.The basic structure of existing fixing ball valve is valve body, valve gap, place the valve ball between valve body and the valve gap, and the valve seat that between valve gap and valve ball, is provided with, under the state of valve closing, form sealing surface between valve seat and the ball valve, and between valve seat and valve gap, also be provided with Regulation spring, its effect mainly is the relative movement that is used between regulating valve seat and the valve ball, to guarantee the normal switch of valve.
And we know; the protection problem of Regulation spring is seldom considered in traditional valve seat construction design; do not prevent that promptly media particle from entering the function of spring working area; Regulation spring is subjected to the corrosion of medium; shorten its working life greatly, in addition, prevents that media particle from entering the function of spring working area even some valve seats have; but the structure of valve seat itself is also very complicated, and its cost of production is also very high.
The model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of simple in structure, cost of production is low and can prolong the Regulation spring valve seat of fixed ball valve in working life.
The utility model is achieved through the following technical solutions:
A kind of valve seat of fixed ball valve, comprise the valve seat body, its one side is fitted with valve ball and is formed sealing surface, another side and valve gap form sealing, between valve seat body and valve gap, also be provided with Regulation spring, Regulation spring is arranged in the groove of valve gap, its two ends prop up valve seat body and valve gap respectively, it is characterized in that: described valve seat body extends to form a step near flowing medium one side direction valve gap, above step, extend to form a platform to the valve seat body by valve gap, step and platform be arranged in parallel, have certain space in the middle of it, and the distance in space is 0.1～0.15mm.
The beneficial effects of the utility model are: the utility model structure is very simple; saved cost of production; improved working efficiency; the platform that utilizes step that valve seat extends to the valve gap direction and valve gap to extend simultaneously to the valve seat direction; prevent that granule medium from entering the spring working zone; reduce the corrosion of particulate matter, form effective protection, prolonged the working life of Regulation spring Regulation spring to Regulation spring.
Description of drawings
Fig. 1 is the utility model one embodiment's a partial schematic sectional view.
Main reference character implication is among the figure:
1, valve ball 2, valve gap 3, valve seat body 4, flowing medium
5, platform 6, step 7, Regulation spring
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail:
Fig. 1 is the utility model one embodiment's a partial schematic sectional view.
As shown in Figure 1: a kind of valve seat of fixed ball valve, comprise valve seat body 3, its one side is fitted with valve ball 1 and is formed sealing surface, another side and valve gap 2 form sealing, between valve seat body 3 and valve gap 2, also be provided with Regulation spring 7, Regulation spring 7 is arranged in the groove of valve gap 2, its two ends prop up valve seat body 3 and valve gap 2 respectively, it is characterized in that: described valve seat body 3 extends to form a step 6 near flowing medium 4 one side direction valve gaps 2, above step 6, extend to form a platform 5 to valve seat body 3 by valve gap 2, step 6 be arranged in parallel with platform 5, has certain space in the middle of it, and the distance in space can be adjusted between 0.1～0.15mm.
In valve working; the particle of flowing medium 4 at the valve through hole through out-of-date; owing to extended step 6 and platform 5 to the other side's direction respectively between valve seat body 3 and the valve gap 2; and the space distance limit between them is between 0.1～0.15mm; and the particle diameter of general flowing medium 4 all is greater than 0.15mm; therefore in the working area of its Regulation spring 7 of in the valve through hole of flowing through, can not entering; therefore structural ledge 6 structural defences of valve seat Regulation spring 7 be not subjected to the corrosion of flowing medium 4, prolonged the working life of Regulation spring 7.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
