CN2814050Y - Fast assembling positioning structure for three sector ball valve - Google Patents

Abstract

The utility model relates to a fast assembling positioning structure for a three sector ball valve. At least one positioning side is arranged on the proper point on the external wall surface of the pipe connection portion of a ball valve body. When the ball valve body is in the assembly state, the positioning face is just bunted mutually with a scheduled bolt capable of locking the ball valve body and the sealing covers on both sides, and thus, after the ball valve body is screwed off to separate from the sealing covers on both sides and the ball valve body is disassembled for changing components, the ball valve body can be accurately and rapidly assembled and positioned by the mutual bunting between the positioning side and the bolts.

Description

The quick assembling and positioning structure of three pieces type ball valve

Technical field

The utility model is relevant, more detailed with a kind of three pieces type ball valve, is meant a kind of assembling operation assembling and positioning structure more accurately and fast that makes behind the each dismounting and change part of three pieces type ball valve especially.

Background technique

Known three pieces type ball valve; consist predominantly of a ball valve body and two and be installed on the side seal lid of ball valve body two sides; this ball valve body inside also is equiped with the spheroid of a central tool discharge orifice; can be subjected to the synchronous driven rotary of live axle on ball valve body top; to change the direction of spheroid central authorities discharge orifice; make the fluid flow between two side seals lid be able to be controlled via spheroid; simultaneously; this ball valve body is to give the clamping packing by the plural bolt of locking that stretches through between two side seals lid; wherein; for preventing that internal liquid is unlikely between ball valve body and side seal lid, or by seepage between ball valve body and live axle, usually can be at these positions installing drop-stopping ring and ring set; because these drop-stopping rings and ring set all belong to article of consumption; in use for some time, promptly must change immediately, otherwise be difficult to continue to keep original stopping leak leak preventing effect.

Known ball valve is at the dismounting and change inner body, during such as article of consumption such as drop-stopping ring and ring sets, though can behind demounting bolt, keep a bolt in regular turn, for the rotating fulcrum between ball valve body and two side seals lid, make the ball valve body mode of being outwarded winding break away from two side seals lid, to be convenient for changing carrying out of operation, but during its assembling, because pivot point is only arranged, and, add that ball valve body has certain weight, especially relatively large ball valve without any the position structure design, therefore, general operation person covers in the operating process of accurately being located the discharge orifice of inner spheroid and two side seals at the rotary ball valve body, and regular meeting feels time-consuming effort again, and influence the efficient of ball valve inner body dismounting and change, and make accurately contraposition between the discharge orifice position of inner spheroid and two side seals lid easily; In view of the above, how effectively to promote assembling quality and the efficient of ball valve behind the dismounting and change inner body, its necessity is just arranged.

The model utility content

The purpose of this utility model is, a kind of quick assembling and positioning structure of three pieces type ball valve is provided, be that pipe at ball valve body connects portion's outer wall appropriate location and is provided with at least one locating face, make this ball valve body when assembled state, this locating face just can abut against mutually with a predetermined bolt of locking ball valve body and two side seals lid.

The utility model provides a kind of quick assembling and positioning structure of three pieces type ball valve, and this ball valve includes a ball valve body and two side seals lid; This ball valve body has the valve seat that a pipe meets portion and is positioned at the pipe joint top, this pipe connects portion's lateral direction penetrating a valve opening, insert the spheroid of a central tool discharge orifice in the valve opening, these spheroid two sides also are combined with a drop-stopping ring and a ring set respectively, this valve seat top installing and locating one control unit, this control unit has a live axle; These side seals lid outside connects a delivery line respectively, and four corner positions respectively are formed with a pivoted hole, and respectively by a bolt and the mutual screw lock of a nut, and wherein a bolt and pipe connect the relative position of portion and stretch through and spool establish; It is characterized in that:

This ball valve body, its pipe connect portion's outer wall appropriate location and are provided with the locating face that a predetermined bolt beyond at least one and the rotating fulcrum abuts against the location mutually.

Wherein this pipe outer wall predetermined position one of meeting portion is extended with a positioning block.

Assembling and positioning structure provided by the utility model after ball valve body being outwarded winding break away from two side seals lid and dismounting and change part, is able to obtain accurately and assemble fast positioning function by this locating face and relative bolt abutting against to each other.
