Abstract
The utility model provides a flange form ball valve in an improved structure, which belongs to the technical field of valves and solves the problems of leakage, caused when a leakage protective ring or a filling piece between a valve ball and a valve seat of the present ball valve looses, and the like. The flange form ball valve in an improved structure comprises a valve body in which a passage is arranged, a handle, a valve handle and the valve ball arranged in the valve body, wherein the internal end of the valve handle is connected with the valve ball, the external end of the valve handle penetrates out of the valve body and is connected with the handle, the passage opening of the valve body is provided with two flanges between which a connecting piece is arranged, and the valve body is arranged between the two flanges by the connecting piece. One connecting piece is used by two flanges for clamping the valve body and connecting the two flanges at both ends of the valve body, the flanges can be adjusted to be tight by a nut, so the valve ball and the valve seat are in a favorable sealed state, and the service life of the whole ball valve is prolonged.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of ball valve, particularly a kind of structure improved flange-type ball valve.
Background technique
The opening and closing that generally come the operating line passage by the control ball valve in for any oily or the control of aqueous fluid are finished water, oil or liquid drainage control with this.Therefore must adopt high-quality ball valve to finish above-mentioned drainage control, so when designing its structure, not only will consider its close property performance, and more will have high temperature resistant, high pressure and wear resistance concurrently.
As the disclosed a kind of high temperature Flange Ball Valves of Chinese patent literature [publication number: 2474837], comprise the valve body that has valve pocket and flange, be contained in the valve rod that the spherical valve core seal ring in the body cavity is connected with spool, drive the handle that spool opens and closes, be shaped on threaded connecting body at anti-flange, be connected with the valve pocket on the valve body, and anti-flange connects barred body port top and is combined on the seal ring of spool one side.The flange-type ball valve of this structure comes the sealing of ball valve integral body by the rotation of flange, the problem that exists is: sealing surface hardness is low, not anti-scratch, price quality ratio be low, it is big to be suitable for narrow limitation, popularization is restricted, especially under the high temperature and high pressure difference, it can not solve leakproof circle or the normal caused leakage problem that relaxes that takes place of pad between valve ball and the valve seat effectively, has influenced the normal use of whole ball valve.So be necessary this is improved, use needs to be fit to ball valve.
Summary of the invention
The purpose of this utility model is at existing existing the problems referred to above, and a kind of good seal performance, structure improved flange-type ball valve wear-resistant, high pressure resistant, easy to install are provided.
The purpose of this utility model can realize by following technical proposal: a kind of structure improved flange-type ball valve, comprise inner channelled valve body, handle, valve rod and be arranged on the interior valve ball of valve body, described valve rod is inner to be connected with valve ball, the outer end of described valve rod passes valve body and is connected with handle, it is characterized in that, the place, passway of described valve body is provided with two flanges, be provided with link between two flanges, described two flanges are installed in valve body between two flanges by link.
This structure improved flange-type ball valve mainly is to constitute the three-member type ball valve by two flanges at the place, passway of valve body and valve body, by a link two flanges are clamped valve body again and be connected two ends of valve body, like this after flange and the certain wearing and tearing of valve body generation, by tightening the flange at two ends, make ball valve still be in good sealing state, improved the working life of ball valve.Because this flange is dismountable, so also make things convenient for the installation of whole ball valve and the replacing and the maintenance of part in addition.
In above-mentioned structure improved flange-type ball valve, described valve body is provided with fixed block, and described link passes this fixed block and connects two flanges.By this fixed block the intermediate portion of link is supported, makes two flanges of the firm connection of link and valve body like this.
In above-mentioned structure improved flange-type ball valve, the joint between described flange and the valve body is provided with seal ring.Strengthened the sealability between flange and the valve body like this, prevented to produce and leak.
In above-mentioned structure improved flange-type ball valve, described link is a bolt, and described bolt is fixed on the flange by nut.Can dismantle easily and mounting flange by nuts and bolt, especially after valve ball and valve seat generation wearing and tearing, can tighten flange, make valve ball and valve seat still be in good sealing state, prevent to leak by nut.
In above-mentioned structure improved flange-type ball valve, be provided with pad between described flange and the nut.Be that convenience is bolted on the flange by the nut handle like this.
Compared with prior art, the advantage of this structure improved flange-type ball valve is to be connected two ends of valve body owing to by a link two flanges are clamped valve body, like this after valve ball and valve seat generation wearing and tearing, can tighten flange by nut, make valve ball and valve seat still be in good sealing state, prolonged the working life of whole ball valve.The dismounting of whole ball valve and install all more conveniently in addition can extensively be assemblied in the conveyance conduit of industries such as oil, chemical industry, pharmacy, food and use.
