Description

A kind of ball valve with non-return device

[technical field]

The utility model relates to a kind of ball valve with non-return device, refers to that especially a kind of need one valve member promptly possesses ball valve control switch and the ball-valve structure that prevents the liquid countercurrent effect.

[background technique]

Liquid guide flow all can utilize pipeline to carry out at present, but do not continue on state because in the water conservancy diversion process be, generally all can the time and open or close, so can be equiped with the valve member of control switch on the pipeline, as ball valve etc., and as food processing, chemistry modulation or other course of working, all can require the liquid can not adverse current, reason is that adverse current might cause batch mixing, it is rotten that batch mixing will cause, perhaps produce the chemical change that to expect, so check equipment also is the necessaries that quite generally uses on the pipeline of water conservancy diversion.

As living spaces such as households, can be equiped with many water supply or sewage diversion pipeline in the wall, and the diversion pipeline of its water supply or sewage might conducting under unexpected state, suck sewage as the diversion pipeline that supplies water because of reverse the generation, cause clean water source and sewage mixed flow, so supply channel is except the valve member that installing control opens and closes, installing check equipment also is essential.

In operation as suction pump, suction pump inside need be accumulated the water yield earlier, making suction pump be enough to produce suction in start-up course draws water, so outside the control switching is supplied water in the installing of suction pump dress, also essential installing check equipment, perhaps boiler adds valve member and the check equipment that the thermal water source need install control switch, with blast protection.

Therefore, above-mentioned pipeline is being installed the valve member that uses control switch and is being prevented from still to have following shortcoming on the check equipment of adverse current:

1, the present various valve members of the use of peddling on the market, all are the valve members that are divided into control switch, or for preventing the check valve member merely, and the most basic inflow side and the outflow side of each part valve member all needs to make connected structure and instrument adjustment structure, this connected structure and instrument are adjusted structure and are occupied a lot of volume of valve member and material again, add a check valve member so select to buy the valve member of control switch, spend more expensive and overall weight is laid particular stress on.

2, on the practical set demand, the assembling of general pipeline generally all needs a control switch demand and an anti-adverse current demand, but can only buy a control switch valve member respectively with the present practice cooperates a check valve member to use simultaneously, so when assembling check valve member and control switch valve member, just must add a body, connect check valve member and control switch valve member respectively with body, the fit on formality is numerous and diverse and consuming time.

[summary of the invention]

The purpose of this utility model is at above deficiency, provides a kind of rational in infrastructure, easy to use, safe, and long service life need not to add in addition the ball valve with non-return device of body.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of ball valve with non-return device, comprise valve body, limit, valve body two ends is respectively equipped with connected structure and instrument is adjusted structure, be provided with the runner of perforation in the valve body, a ball-valve structure is established in the inflow side of runner, it is characterized in that: a room space is established in the outflow side of described runner, runner is connected to place, room space and is provided with gradient retaining edge, also be provided with a non-return device in the valve body, non-return device includes a check baffle plate and a tip bar, and check baffle plate top side is pivotally arranged on the valve body with tip bar.

The utility model can further be specially:

The top of described check baffle plate is provided with tip hole, the gradient retaining top, edge place in room space also is provided with tip hole, the tip hole of check baffle plate is with after aliging in the tip hole in room space, by the tip bar check baffle plate and room space are worn group together, closely connected during the check flapper closure in nearly gradient retaining edge and sealing runner.

Described ball-valve structure includes leader, an axis and a spheroid, spheroid is located on the runner of valve body inflow side, valve body assembling spheroid position is provided with through hole towards the outside of vertical run, spheroid is provided with the through hole of the runner that can align, one end of described axis is connected to spheroid, the axis the other end is passed by the through hole of valve body, and the free termination that axis passes is established the leader.

Described this valve body is made by one-body molded.

Described connected structure can be internal thread.

Described instrument is adjusted structure and be can be hexagonal body or octagon.

The utility model advantage is:

1. the utility model provides a kind of ball valve with non-return device, and what wherein promptly be provided with spheroid control switch runner and check baffle plate on this integrated valve body runner prevents the liquid countercurrent dual functions.

2. the utlity model has the ball valve of non-return device, the one valve member has switch control and non-return function simultaneously, and this valve member only need be made two rank instruments and adjusts structure, and overall volume is significantly dwindled, weight saving and material economization.

3. the ball valve with non-return device of the present utility model, with a valve member buy cost get final product two kinds of functions, and the also general assembling of the fit on of this valve member quicker with more save time, pipe fitting.
