Abstract
The utility model provides an all-welded floating ball valve. The all-welded floating ball valve comprises a valve rod, a left valve deck, a right valve deck, springs, metal supporting rings, valve seats, a ball body and a valve rod. The left valve deck and the right valve deck are arranged on the left side of the valve body and the right side of the valve body respectively. The ball body is arranged in the valve body. The end portion, close to the ball body, of each valve deck is provided with one floating valve seat. The valve rod is connected to the top of the ball body. The left side surface and the right side surface of the ball body are installed on the two valve seats respectively. Each metal supporting ring is installed on an inner hole of one valve seat and the bottom face of the valve seat in a supported mode. Each pre-tensioned spring is arranged between the reverse side of one valve seat and one valve deck. According to the all-welded floating ball valve, due to the facts that an O-shaped ring is arranged on the outer circle of the floating valve seats and seals the floating valve seats, and the inner hole and the bottom face of each valve seat are supported by one metal supporting ring, the fireproof function and the sealing ring reinforcement function are achieved. Each butterfly spring abuts against the reverse side of one valve seat, so that the function that the inlet valve seat and the outlet seat are sealed at the same time is achieved and the sealing reliability of the ball valve is guaranteed.
Description
Technical field
The utility model belongs to the ball valve field, is specifically related to a kind of full welding floating ball valve.
Background technique
Ball valve was come out the 1950's, and along with the develop rapidly of science and technology, updating of production technology and product structure, in the 40 short years, developed rapidly and become a kind of main valve class.In the west flourishing country of industry, the use of ball valve is constantly risen year by year, in China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.
It has the action of 90-degree rotation ball valve, and faucet body is spheroid, manhole or passage is arranged by its axis.Ball valve is mainly used to make cut-out, distributes and change medium in pipeline flow direction, it only need to just can be closed tightly with the operation of 90-degree rotation and very little moment of rotation.The ball valve optimum is made switch, cut-off valve uses, but recent development has become to make it to have the use of throttling and control flow with ball valve design, as the V-type ball valve.But,, owing to often can mutually rotating between the inner spheroid of ball valve and valve seat, be easy to destroy sealing, cause leaking after valve closing.
The model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of sealing full welding floating ball valve reliably.
The utility model is achieved by the following technical solution:
A kind of full welding floating ball valve, is characterized in that, comprises valve body, left and right two valve gaps, spring, metallic support circle, valve seat, spheroid and valve rod, and left and right two valve gaps are separately positioned on the left and right sides of valve body, and spheroid is arranged on valve inner; Each valve gap is provided with a valve seat that floats near the end of spheroid, and valve rod is connected to the top of spheroid, and the left and right side of spheroid is arranged on respectively on two valve seats; The metallic support circle supports and is arranged on the endoporus and bottom surface of valve seat, is provided with the spring of pretension between the back side of valve seat and valve gap.
Further setting of the present utility model is, described spring is a butterfly spring.
Further setting of the present utility model is, is provided with the O RunddichtringO between the cylindrical of described valve seat and valve gap.
Further setting of the present utility model is, described metallic support circle is a race ring.
Further setting of the present utility model is, described left and right two valve gaps are connected by welding manner with valve body.
Full welding floating ball valve described in the utility model, by join the sealing of O type circle at the floating valve seat cylindrical, valve seat endoporus and bottom surface are supported and are had fire prevention and the effect of enhanced leaktightness circle by the metallic support circle, the butterfly spring pretension is adopted at the back side, can reach import export valve seat sealing function simultaneously, guarantee the sealing reliability of ball valve.
Description of drawings
Fig. 1 is the structural drawing of full welding floating ball valve described in the utility model;
In figure, each label is: valve body 1, valve gap 2, spring 3, metallic support circle 4, valve seat 5, O type circle 6, spheroid 7, valve rod 8.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of full welding floating ball valve, comprise valve body 1, left and right two valve gaps 2, spring 3, metallic support circle 4, valve seat 5, spheroid 7 and valve rod 8, left and right two valve gaps 2 are separately positioned on the left and right sides of valve body 1, and spheroid 7 is arranged on valve body 1 inside; Each valve gap 2 is provided with a valve seat 5 that floats near the end of spheroid 7, and valve rod 8 is connected to the top of spheroid 7, and the left and right side of spheroid 7 is arranged on respectively on two valve seats 5; Metallic support circle 4 supports and is arranged on the endoporus and bottom surface of valve seat 5, is provided with the spring 3 of pretension between the back side of valve seat 5 and valve gap 2, and described spring 3 is a butterfly spring, and described metallic support circle 4 is a race ring.Be provided with O RunddichtringO 6 between the cylindrical of described valve seat 5 and valve gap 2.The multiple action of O RunddichtringO 6, metallic support circle 4 and pretension butterfly spring 3 in the utility model, make the sealing reliability of this ball valve greatly improve.Described left and right two valve gaps 2 are connected by welding manner with valve body 1, make the better tightness of ball valve.
