Abstract
The utility model provides an energy-saving three-piece American-standard flange-type ball valve. The energy-saving three-piece American-standard flange-type ball valve comprises a left valve cover, a right valve cover, a main valve body and a valve rod. The outer end portion of the left valve cover and the outer end portion of the right valve cover are respectively provided with a flange connecting bolt hole used for being connected with a flange. The left valve cover and the right valve cover are connected together through middle flange bolts. The main valve body is arranged between the left valve cover and the right valve cover. A valve cavity is formed in the main valve body. A valve seat is arranged in the valve cavity. A ball body is arranged on the valve seat. The ball body is fixedly connected with one end of a valve rod and the other end of the valve rod stretches out of the main valve body to be connected with a handle. The included angles between the central axes of the flange connecting bolt holes and the central axes of the middle flange bolts are 45 degrees. By the adoption of the structural design that the central axes of the flange connecting bolt holes at the two ends and the central axes of the middle flange bolts are staggered by 45 degrees, the phenomenon that the bolts interfere with each other during connection so that the bolts cannot be installed can be avoided, and installing difficulty is reduced.
Description
Technical field
The utility model belongs to the ball valve field, is specifically related to a kind of energy-saving three American Standard flange type ball valves.
Background technique
Ball valve is to use with the spheroid of circular channel to make open-shut device, and spheroid rotates the valve of realizing switching motion with valve rod.The open-shut device of ball valve is a porose spheroid, around the axis rotation perpendicular to passage, thereby reaches the purpose that opens and closes passage.Ball valve is mainly used in blocking or connects pipeline and equipment medium, also can be used for adjusting and the control of fluid, and the ball valve fluid resistance is little, and is simple in structure, and volume is little, and is lightweight, and closely reliable, operation and maintenance is convenient, can not cause the erosion of valve sealing face, and is applied widely.The chip ball valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, but the more complicated when mounted of American Standard flange type ball valve at present on the market.
The model utility content
The utility model provides a kind of easy-to-install energy-saving three American Standard flange type ball valves for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of energy-saving three American Standard flange type ball valves is characterized in that, comprise left and right two valve gaps, main valve body and valve rods, and the outer end of described left and right two valve gaps is provided with for the adpting flange bolt hole that is connected with flange; Left and right two valve gaps link together by the spacer flanger bolt; Main valve body is arranged between left and right two valve gaps, is provided with valve pocket in main valve body, is provided with valve seat in described valve pocket, is provided with spheroid on described valve seat, and spheroid is fixedly connected with an end of valve rod, and the other end of valve rod stretches out outside main valve body and is connected with handle; The angle of 45 ° is arranged between the central axis of the central axis of adpting flange bolt hole and spacer flanger bolt.
Further setting of the present utility model is, is provided with the valve seat mounting groove in described main valve body, and valve seat is arranged in the valve seat mounting groove; The degree of depth of described valve seat mounting groove equals half of the inboard flange thickness of valve gap.
Further setting of the present utility model is, in valve gap, the end face wall thickness of side flange is more than or equal to its radial thickness.
Further setting of the present utility model is, is provided with lock dog and handle latch on described handle.
Energy-saving three American Standard flange type ball valves described in the utility model have following beneficial effect:
1, the utility model adopts two ends adpting flange bolt center hole and the spacer flanger bolt center hole structural design of 45 ° that staggers, and does not produce mutual interference in the time of can avoiding like this bolt connection and can't install, and has reduced installation difficulty.
2, the utility model designs without undergauge, can also guarantee American Standard minimal structure length.
3, the utility model adopts the structural design of small belly, namely improves the compressive strength of valve body and can save again many raw-material wastes.
4, the utility model valve seat mounting groove degree of depth approximate thick half of middle flange left and right and guarantee in the end face of flange wall thickness be not less than the flange radial thickness, but this mode shortening structure is long, the assurance minimal structure is long.
Description of drawings
Fig. 1 is the structural drawing of energy-saving three American Standard flange type ball valves described in the utility model;
In figure:
