Abstract
The utility model discloses a floating ball valve which comprises a handle, a pressing cover, a pressing sleeve, a valve rod, a spherical body, a seal ring and a valve body, wherein one end of the handle is fixed at one end of the valve rod; the other end of the valve rod penetrates through the valve body and is connected with the spherical body; a clearance is formed between the valve body and the spherical body; the seal ring is arranged in the clearance between the valve body and the spherical body; the seal ring is provided with a V-shaped groove; and a V-shaped metal spring ring is arranged in the V-shaped groove. The floating ball valve is simple in structure, good in sealing property, low in processing cost, easy to manufacture, safe, reliable, energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of floating ball ball valve.
Background technique
The spheroid of ball valve floats, and under the pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantees the outlet end sealing.
Floating ball ball valve simple in structure, good airproof performance has all been passed to the exit seal circle but spheroid bears the load of working medium, therefore will consider that can sealing ring material hold out against the work loads of spheroid medium, when being subject to the elevated pressures impact, spheroid may be offset.This structure generally is used for the mesolow ball valve.
The main feature of ball valve is compact structure own, sealing is reliable, simple in structure, easy to maintenance, sealing surface and the sphere closed state of being everlasting, be difficult for by the medium erosion, easy operating and maintenance are applicable to the general work media such as water, solvent, acid and rock gas, but also are applicable to the abominable medium of operating conditions, as oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade.Ball valve body can be whole, can be also knockdown.
the sealing of tradition floating ball ball valve mainly realizes press seal by the contention effect of spheroid at spheroid face and seal ring inner face by medium, under the state that ball valve is closed, two parts that the seal ring of conventional construction is isolated into sealing with entrance point and the cavity of ball valve, wherein the medium in cavity more easily is subject to temperature because volume is little, the impact of pressure and produce media expansion in cavity, increase the valve switch moment of torsion, easily cause the sealing configuration distortion of seal ring under the state that pressure can not get discharging, under the state that ball valve is opened, seal ring can not automatically restore to original state, cause distortion and the wearing and tearing of seal ring under reciprocal this state, affect the working life of seal ring.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of floating ball ball valve of a kind of simple in structure, good airproof performance, long service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of floating ball ball valve, comprise handle, gland, gland, valve rod, spheroid, seal ring and valve body, one end of described handle is fixed on an end of described valve rod, the other end of described valve rod passes valve body and is connected with spheroid, leave the gap between described valve body and spheroid, described seal ring is placed in the gap of valve body and spheroid, and described seal ring is provided with the V-type groove, is mounted with V-type metal elastic spring coil in described V-type groove.
In an embodiment of the present utility model, symmetrically in the gap between described valve body and spheroid be provided with 4 seal rings.
In an embodiment of the present utility model, described seal ring is made by rubber or plastics.
By technique scheme, the beneficial effects of the utility model are:
The utility model is offered the V-type groove on seal ring; and V-type metal elastic spring coil is set in the V-type groove; it makes original seal ring have the elastic compensating effect; except the effective sealing medium; also reduce the switching torque of valve; and long-term sealing surface wear and the distortion of using the seal ring that causes of compensation, the protection seal ring is not damaged, and extends its working life.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of the A in Fig. 1.
Numeral and the represented corresponding part title of letter in figure:
10, handle 20, gland 30, gland 40, valve rod 50, spheroid 60, seal ring 61, V-type groove 62, V-type metal elastic spring coil 70, valve body.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to illustrated in figures 1 and 2, a kind of floating ball ball valve of the utility model comprises handle 10, gland 20, gland 30, valve rod 40, spheroid 50, seal ring 60 and valve body 70, one end of handle 10 is fixed on an end of valve rod 40, the other end of valve rod 40 passes valve body 70 and connects in spheroid 50, leave the gap between valve body 70 and spheroid 50, seal ring 60 is placed in the gap of valve body 70 and spheroid 50, and seal ring 60 is provided with V-type groove 61, is mounted with V-type metal elastic spring coil 62 in V-type groove 61; This Novel sealing ring effectively reduces the spheroid of floating ball ball valve and wearing and tearing, distortion and the increase valve switch moment of torsion that conventional seals circle Yin Wendu, pressure factor produce seal ring; This Novel sealing ring has the elastic compensating effect, except the effective sealing medium, also reduces the switching torque of valve, and compensates long-term seal ring sealing surface wear and the distortion that causes of using, and the protection seal ring is not damaged, and extends its working life.
Symmetrically in gap between the utility model valve body and spheroid be provided with 4 seal rings, it can realize even sealing, has improved the stability of sealing.
The utility model seal ring is made by rubber or plastics, and its corrosion resistance is strong, long service life, and processing cost is low.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
