A valve

Technical Field

The utility model relates to a steering valve belongs to valve technical field.

Background

Valves are devices that utilize a movable member to open, close, or partially block one or more openings or passages to allow a flow of liquid, air or other gas or bulk material to exit, block, or be regulated.

The existing ball valves are generally straight-through ball valves, and the function of the existing ball valves is to open or block the circulation of media in a 'straight' pipeline, however, in some special cases, the media in the pipeline need to be reversed, so people also develop a 'right-angle ball valve' which can be used for reversing the media in the pipeline.

However, when the right-angle ball valve is installed, the installation accuracy requirement on the valve seat is very high, if the accuracy of the installation position of the valve seat is not high, the problem of poor sealing performance is very easy to occur, and when the problem of sealing performance occurs, the steering valve can be leaked. For example: in order to realize the sealing of the ball in the right-angle ball valve, at least 3 valve seats are required to be matched with the ball to realize the sealing of the valve, as shown in fig. 5, but when the installation precision of one valve seat is not effectively guaranteed (as shown in fig. 6), leakage occurs at the matched part of the valve seat and the ball.

Based on the statement, in order to improve the sealing effect of the right-angle ball valve and reduce the requirement of the right-angle ball valve on the installation precision of the internal valve seat, a novel valve body structure needs to be proposed urgently to overcome the problems.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model discloses the connection that mentions divide into fixed connection and can dismantle the connection, fixed connection is for the conventional fixed connection mode such as undetachable connection including but not limited to hem connection, rivet connection, adhesive connection and welded connection, can dismantle the connection including but not limited to conventional dismantlement modes such as threaded connection, buckle connection, pin joint and hinged joint, when not clearly prescribing a limit to concrete connection mode, acquiesces to always can find at least one kind of connected mode in current connected mode and can realize this function, and the technical staff in the art can select by oneself as required. For example: the fixed connection selects welding connection, and the detachable connection selects hinge connection.

The first embodiment is as follows: the present embodiment is described with reference to fig. 1 to 4, and a valve of the present embodiment includes a valve body 1, a valve stem 2, and a ball core 3, and is characterized in that: be provided with the valve rod 2 with the linkage of ball core 3 in the valve body 1, valve rod 2 is installed in valve body 1 and is stretched out from the side of valve body 1, install first disk seat 4 and second disk seat 5 in the valve body 1, first disk seat 4 and second disk seat 5 form sealed vice with ball core 3, ball core 3 includes spheroid 6 and body 7, spheroid 6 and body 7 integrated into one piece.

Furthermore, a wrench 8 is installed on the outer side of the valve rod 2, and the wrench 8 drives the ball core 3 to rotate, so that the valve is opened and closed;

furthermore, a connecting pipe 9 is installed on the valve body 1 in a threaded connection mode in a matched mode, the connecting pipe 9 is provided with a built-in groove 10, a second valve seat 5 is installed inside the groove 10, the second valve seat 5 is installed in the groove 10 in an interference fit mode, and internal threads are processed on the connecting pipe 9 and used for being installed in a threaded fit mode with other connecting pipes;

furthermore, a first through hole 11 is processed on the sphere 6, a second through hole 12 is formed on the tube body 7, and the first through hole 11 is communicated with the second through hole 12. And the central line of the first through hole 11 is vertically intersected with the central line of the second through hole 12.

Further, a connector 13 is installed on the valve body 1 in a threaded connection mode in a matched mode, and the connector 13 is communicated with the pipe body 7.

In this embodiment, valve body 1 is square valve body, through the valve structure that two sets of "valve rod 2, ball core 3 and disk seat" formed in the valve body 1, and the back is accomplished in the equipment, and the medium passes through in connecting pipe 9 gets into valve body 1, through spheroid 6, and the medium flows in spheroid 6 and turns to, and the medium flows into in the body 7, then flows out through adapter 13, so far realizes the medium circulation switching-over.
