Abstract

The utility model discloses an automatic disconnection ball valve, which comprises a valve body connecting an upper stream and a lower stream of a pipeline, a valve ball arranged in the valve body, a valve rod connected with the valve ball, a cylindrical through hole is axially arranged on the valve ball, and a commutation device is connected with the valve ball through the valve rod and arranged outside the valve body. The commutation device for controlling a main valve is arranged outside the valve body so that the automatic disconnection ball valve has the advantages that the control of the main valve can be achieved through an externally arranged device and the control is facilitated. The commutation device arranged outside the valve body is easier to clean and maintain and capable of simplifying frequent maintenance work of the pipeline valve caused by the fact that media in the pipeline often carries impurities.

Description

Self-powering type cuts off ball valve
Technical field
The utility model relates to a kind of valve, and a kind of specifically self-powering type cuts off ball valve.
Background technique
Relying on oneself and cutting off ball valve is a kind of quarter-turn structure, and it and the supporting use of valve positioner can the adjustings of realization ratio.Its principle is that the operating device motion drives the valve rod rotation, and valve rod drives valve ball again and rotates.When valve ball turns to the authority position of positioning block design, stop operating, position indicator pointed to and opened or closed this moment.When turning to the position indicator when opening, it is consistent that the passage of valve ball and valve body are imported and exported direction, and ball valve is in opening state.When position indicator closed, the passage of valve ball was vertical with valve body import and export direction, and it is in closed condition.
Traditional pneumatic valve is to adopt source of the gas, power supply or selector valve to control main valve, accomplishes the rotation of valve ball.Its self-powering type cut-off valve utilizes pipeline self pressure source, through selector valve control main valve.
The model utility content
The purpose of the utility model provides a kind of self-powering type and cuts off ball valve, and the reversing arrangement that will be used to control main valve is arranged on the valve body outside, and controlling through external device of main valve can be accomplished, and is convenient to cleaning and maintenance.
For realizing above-mentioned purpose; The utility model provides a kind of self-powering type and cut off ball valve; Comprise the connecting tube upstream and downstream valve body, be arranged at valve ball in the said valve body, be connected in the valve rod of said valve ball, said valve ball has a cylindrical body through hole vertically, a reversing arrangement is connected in said valve ball through said valve rod; The top of described valve rod is provided with a reversing arrangement, and said reversing arrangement is connected with the valve ball of being located at stem lower portion through valve rod.
Above-mentioned self-powering type cuts off ball valve, and said reversing arrangement comprises: Hydraulic actuator, said Hydraulic actuator are positioned at outside the said valve body and with said valve rod and are connected; External pipeline, said external pipeline comprise the upstream that connects upstream line and said Hydraulic actuator, and the downstream pipeline that connects said Hydraulic actuator and downstream line; Solenoid valve, said solenoid valve are installed between said upstream and the said downstream pipeline, and are used to control the break-make between said upstream and the said downstream pipeline.
Above-mentioned self-powering type cuts off ball valve, and is preferred, is provided with the filler that is used to fill slit between said valve rod and the said valve body between said valve rod and the said valve body.
Above-mentioned self-powering type cuts off ball valve, is provided with the Gland that is used to compress said filler along said valve rod periphery.
Above-mentioned self-powering type cuts off ball valve, is provided with the valve seat that is used for strengthening sealing effect between said valve ball and the said valve interior wall.
Above-mentioned self-powering type cuts off ball valve, and said valve seat is an annulus.
The utility model self-powering type cuts off the reversing arrangement that ball valve will be used to control main valve and is arranged on the valve body outside, and its technique effect is:
1. controlling through external device of main valve can be accomplished, and is convenient to control;
2. be installed in outside reversing arrangement and clean more easily and keep in repair,, often need carry out pipeline valve and safeguard, reversing arrangement is installed in the outside of valve body, simplified above-mentioned valve maintenance work because ducted medium is entrained with impurity usually.
Description of drawings
Fig. 1 cuts off the structural representation of ball valve for the utility model self-powering type.
The drawing reference numeral explanation:
The 1-solenoid valve, the 2-Hydraulic actuator, the 3-Gland, the 4-filler, the 5-valve rod,
The 6-valve seat, 7-valve ball, 8-valve body.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 1; Self-powering type cut off ball valve comprise the connecting tube upstream and downstream valve body 8, be arranged at valve ball 7 in the valve body 8, be connected in the valve rod 5 of valve ball 7; Valve ball 7 has a cylindrical body through hole vertically, and a reversing arrangement is connected in valve ball 7 through valve rod 5, and reversing arrangement is positioned at the outside of valve body 8.Here the upper reaches of said pipeline are meant the part of this pipeline medium by the pipeline flow-direction valve body, and the downstream of pipeline are meant that this pipeline medium is flowed to the part of pipeline by valve body; That is, ducted medium is by the upstream flow of the pipeline downstream to pipeline.
Above-mentioned reversing arrangement specifically, comprises three parts.They are respectively:
(1) Hydraulic actuator 2, and Hydraulic actuator 2 is positioned at outside the valve body 8 and with valve rod 5 and is connected;
(2) external pipeline comprises upstream and downstream pipeline.Wherein, upstream is meant the pipeline that connects upstream line and Hydraulic actuator 2; The downstream pipeline is meant the pipeline that connects Hydraulic actuator 2 and downstream line;
(3) solenoid valve 1, and solenoid valve 1 is installed between upstream and the downstream pipeline, and is used to control the break-make between upstream and the downstream pipeline.
Further, this self-powering type cuts off ball valve, is provided with filler 4 between valve rod 5 and the valve body 8, and filler 4 is used to fill the slit between valve rod 5 and the valve body 8.Be provided with the Gland 3 that is used to compress filler 4 along valve rod 5 peripheries.Filler 4 is filled in the slit between Gland 3, valve body 8 and the valve rod 5, utilizes mechanical parts such as bolt that Gland 3 is fixing, is pressed on the filler 4.Like this, when rotatablely moving under the control of valve rod 5 at reversing arrangement, valve rod 5 fits tightly with its parts on every side, has prevented that circulation medium from overflowing.
Further, be provided with valve seat 6 between valve ball 7 and valve body 8 inwalls, valve seat 6 is used for strengthening the sealing effect of pipeline.Valve ball 7 is two circumference with the shape at valve body 8 inwall contact position edges, and the shape of valve seat 6 can be corresponding with above-mentioned two circumference, and promptly valve seat is shaped as annulus.Valve seat 6 is installed between valve ball 7 and the valve body 8.The wearing and tearing of valve ball 7 and valve body 8 have been reduced like this, on the one hand; On the other hand, also further resistance the circulation medium leakage, increased the sealing effect of pipeline.
Those skilled in the art will recognize that; Above-mentioned embodiment is exemplary; Be in order better to make those skilled in the art can understand this patent; Can not be interpreted as it is restriction to this patent protection domain, so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection
