Abstract
The utility model discloses a double-blocking and double-bleeding ball valve. The double-blocking and double-bleeding ball valve comprises a valve body and an end cover arranged on the upper end face of the valve body. A pipeline is arranged inside the end cover, and a ball is arranged inside the pipeline and divides the pipeline into an upstream pipe portion and a downstream pipe portion. Two bleeding pipes are arranged on the end cover and communicated with the pipeline, one bleeding pipe is communicated with the upstream pipe portion, the other bleeding pipe is communicated with the downstream pipe portion, each bleeding pipe is provided with a bleeding valve, and a bleeding plug screw is arranged on the free end of each bleeding pipe. The end cover is provided with the bleeding pipes respectively corresponding to the upstream pipe portion and the downstream pipe portion, each bleeding pipe is provided with the bleeding valve, the bleeding plug screw is arranged on the free end of each bleeding pipe, and therefore in the process of maintenance, people just need to unscrew the bleeding plug screws and open the bleeding valves, then residual media in the upstream pipe portion and the downstream pipe portion can be discharged, and potential safety hazard does not exist.
Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to the two ball valves that diffuse of a kind of double block.
Background technique
Ball valve is developed by stopcock, its open-shut device is as a spheroid, utilize spheroid to realize the purpose of opening and closing around the axis half-twist of valve rod, ball valve is mainly used in cutting off, distributes and changes the media flow direction at pipeline, spheroid is separated into upstream tube part and downstream tube part with ball valve, after ball valve is closed, medium in medium in the upstream tube part and the downstream tube part just is blocked, form double block, and there is medium residual in upstream tube part and the downstream tube part, operation and the maintenance of pipeline brought potential safety hazard.
The model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can solve the operation of pipeline and the two ball valves that diffuse of double block of maintenance potential safety hazard.
The technical solution of the utility model is achieved in that the two ball valves that diffuse of a kind of double block, it comprises valve body, be located at the end cap of described valve body upper-end surface, be provided with pipeline in the described end cap, be provided with spheroid in the described pipeline, described spheroid is divided into upstream tube part and downstream tube part with described pipeline, be provided with two exhaust stacks on the described end cap, described two exhaust stacks and described pipeline communication, wherein a described exhaust stack partly is communicated with upstream tube, the described exhaust stack of another root partly is communicated with downstream tube, be provided with diffusion valve on the every described exhaust stack, the free end of every exhaust stack is provided with and diffuses plug screw.
Preferably, between described end cap and the valve body, between end cap and the exhaust stack, be welded and fixed respectively between exhaust stack and the diffusion valve.
The utility model has the advantages that: be provided with respectively the exhaust stack corresponding with upstream tube part, downstream tube part at end cap, and be provided with diffusion valve at every exhaust stack, the free end of every exhaust stack is provided with and diffuses plug screw, during maintenance, only need twist off and diffuse plug screw, open diffusion valve and can discharge upstream tube part, the interior residual medium of downstream tube part, do not produce security hidden trouble.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is the structural representation of present embodiment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Consult shown in Figure 1, the two ball valves that diffuse of a kind of double block of present embodiment, it comprises valve body 1, is located at the end cap 2 of valve body 1 upper-end surface, be provided with pipeline in the end cap 2, be provided with spheroid 3 in the pipeline, spheroid 3 is divided into upstream tube part 4 and downstream tube part 5 with pipeline, be provided with two exhaust stacks 6 on the end cap 2, two exhaust stacks 6 and pipeline communication, wherein an exhaust stack 6 is communicated with upstream tube part 4, another root exhaust stack 6 is communicated with downstream tube part 5, is provided with diffusion valve 7 on the every exhaust stack 6, and the free end of every exhaust stack 6 is provided with and diffuses plug screw 8.
In order to guarantee that the two sealings of diffusing ball valve of double block are reliable, intensity is high, leak free problem, then between the end cap 2 and valve body 1 of present embodiment, between end cap 2 and the exhaust stack 6, be welded and fixed respectively between exhaust stack 6 and the diffusion valve 7.
When double block is two diffuse ball valve and close after, direction is obstructed mutually with regard to being blocked for the medium of the medium in the upstream tube part 4 and downstream tube part 5, just form double block, after ball valve is closed, there is respectively medium residual in the upstream tube part 4 He in the downstream tube part 5, before the maintenance pipeline, twist off and diffuse plug screw 8, then open diffusion valve 7, can respectively the residual medium in upstream tube part 4 and the downstream tube part 5 be discharged, and conveniently the medium in upstream tube part 4 and the downstream tube part 5 be carried out sample analysis.
Above mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with technique understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
1. two ball valves that diffuse of a double block, it comprises valve body, be located at the end cap of described valve body upper-end surface, be provided with pipeline in the described end cap, be provided with spheroid in the described pipeline, described spheroid is divided into upstream tube part and downstream tube part with described pipeline, it is characterized in that: be provided with two exhaust stacks on the described end cap, described two exhaust stacks and described pipeline communication, wherein a described exhaust stack partly is communicated with upstream tube, the described exhaust stack of another root partly is communicated with downstream tube, be provided with diffusion valve on the every described exhaust stack, the free end of every exhaust stack is provided with and diffuses plug screw.
