Abstract
The utility model discloses a sealed ball valve, including valve body, ball, valve rod, seal gasket and adapting unit, the valve rod penetrates inside the valve body from the upper end, the ring channel that is equipped with the stairstepping one is served what be connected with adapting unit to the valve body, adapting unit's ripper ring surface on be provided with annular seal step, characterized by is established on annular seal step to the seal gasket cover: annular seal step's outer axle head on be provided with the v groove part. Take the utility model discloses a sealed ball valve can be so that valve body, seal gasket, joint adapting unit be closely fixed, and the live time is longer, and sealed effect is better, but the wide application on copper ball valve, stainless steel ball valve, high temperature high pressure ball valve, increase of service life.
Description
Technical field
This utility model relates to a kind of seal ball-valve, is specifically designed a kind of seal ball-valve.
Background technology
Ball valve is developed by cock, and its opening and closing element, as a spheroid, utilizes spheroid around the purpose of the axis half-twist realization opening and closing of valve rod.Ball valve is mainly used in cutting off, distributing and change media flow direction on pipeline, ball valve is not only simple in structure, good seal performance, and certain nominal stimulate the menstrual flow scope inner volume compared with little, lightweight, material consumption is few, installation dimension is little, and driving moment is little, easy and simple to handle, easily realize fast opening and closing, ball valve is one of valve kind with fastest developing speed in recent ten years.
Ball valve uses comparatively general in valve field, therefore sealing property can become its emphasis all the time and solves the technical problem that, the lower surface of valve rod is generally plane, therefore, in use, valve rod can be subject to the impact of pressure medium, pressure is difficult to balance, thus causing valve rod off-center, ultimately resulting in sealing reduction and causing leakage so that the service life of ball valve is not high.
Summary of the invention
For solving the problems referred to above, this utility model is in that offer one is high temperature resistant, sealing effectiveness better, the seal ball-valve that service life is longer.
The technical solution adopted in the utility model is to provide a kind of seal ball-valve, and including valve body, ball, valve rod, gasket seal and connection member, described valve rod penetrates valve inner from upper end；Described valve body is provided with step-like cannelure on the one end being connected with connection member, the support ring outer surface of described connection member is provided with ring packing step, described gasket seal is set on ring packing step, and the axially outer end of ring packing step is provided with V-shaped seam.
Further, the length of described V-shaped seam is 0.3mm-0.5mm.
Further, described gasket seal is politef circle or rubber ring.
Further, what described ball adopted is metal material, and the central authorities of ball are provided with ball.
Taking seal ball-valve of the present utility model, it is possible to valve body, gasket seal, joint connection part are tightly fastened, use the time longer, sealing effectiveness is better, can be widely used on copper ball valve, stainless steel ball valve, high-temp and-pressure ball valve, increases the service life.
Accompanying drawing explanation
Fig. 1 is this utility model sectional view.
Fig. 2 is this utility model connection member sectional view.
In figure: 10, valve body, 11, passage, 12, cannelure, 20 valve rods, 30, ball, 31, ball through hole, 40 connection members, 41, ring packing step, 50, gasket seal, 60, V-shaped seam
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Seeing Fig. 1 seal ball-valve of the present utility model, including valve body 10, ball 30, valve rod 20, gasket seal 50 and connection member 40, it is internal that described valve rod 20 penetrates valve body 10 from upper end；Described valve body 10 is provided with step-like cannelure 12 on the one end being connected with connection member 50, the support ring outer surface of described connection member 40 is provided with ring packing step 41, described gasket seal 50 is set on ring packing step 41, and the axially outer end of ring packing step 41 is provided with V-shaped seam 60.
Main valve body 10 has the passage 11 of this main valve body 10 through, valve body 10 is built with ball 30 close-fitting with connection member 40, thus along with the rotation of this valve rod 20, rotation followed by this ball 30, the through hole 31 of ball is changed, thus realizing the unimpeded of passage 11 and closedown by 0-100% with the registration of this passage 11.
As in figure 2 it is shown, it is 0.3mm-0.5mm that V-shaped stitches 60 length, quantity is 1-2 bar.
As shown in Figure 1, in concrete assembling process, ball joint sealing cushion rubber is placed in the groove of support ring inner ring of connection member 40, gasket seal 50 is set on ring packing step 41, then the connection member 40 assembled being rotated into together in valve body, after valve body 10 and connecting portion 40 tighten, gasket seal 50 is with cannelure 12 compact siro spinning technology of connection member 40, valve body, formation point, line, surface seal, and reach dual layer sealing effect.
Further, described annular sealing gaskets 50 is politef circle or rubber ring.
Above example is simply to illustrate that this utility model, it is thus understood that this utility model is not limited to above example, meets the various variants of utility model thought all within protection domain of the present utility model.
