Description

一种用于管道疏通器的接头 Drain fitting for a filter

技术领域 FIELD

本实用新型涉及一种管道疏通器零部件,尤其涉及一种用于管道疏通器的接头。 The present invention relates to a dredge pipe parts, particularly to a pipe joint dredge. 背景技术 Background technique

日常生活中,下水管道易被污物堵塞,因此市场上出现了多种管道疏通器,专业管道疏通人员常使用的是一种机械疏通机,它是通过机械旋转绞刀绞出管道内的阻塞物,这种机器的缺陷是比较笨重,结构复杂成本高,且需要专业的技术人员来操作, 不适合日常家庭使用。 Daily life, susceptible to dirt clogging sewer, resulting in a drain on the market various professional personnel drain commonly used is a mechanical cleaning machine, which is obtained by a mechanical rotary cutter Daojiao an obstruction in the duct matter, this defect of the machine is relatively bulky, complex structure and high cost, and the need for professional technical personnel to operate, not suitable for everyday family use. 还有一种是比较简易的疏通工具,俗称水拔子,该工具虽然结构简单,成本低,但其吸力较小,疏通效果不理想,并且在使用时常有脏水四溅,很不卫生。 There is also a relatively simple and clear tool, commonly known as water pull the child, the tool is simple structure, low cost, but its small suction dredge result is not satisfactory, and often have to use dirty water splashes, not health.

现在欧美等许多国家的家庭主要食用淀粉类食物,而淀粉与糖类混合物更容易堵 Now the family in many countries in Europe and America and other major consumption of starchy foods, and a mixture of starch and sugars more easily blocked

塞管道。 Plug the pipeline. 为此,出现了一种利用水的压力将管道内的堵塞物冲走,实现疏通管道目的管道疏通器,如一专利号为ZL91212787.2(公告号为CN2088907Y)的中国实用新型专利《管道疏通器》披露了一种这样的结构, 一种管道疏通器,它由进水软管,连接硬管及注水头组成。 For this reason, there has been utilizing the pressure of the water within the pipe plug away, to achieve pipeline dredge dredge pipe object, such as a Patent No. ZL91212787.2 (Publication No. is CN2088907Y) in Chinese utility model patent "pipeline dredge "One such configuration is disclosed a drain, which consists of water hoses, pipe lines and water headers. 使用时将进水软管接在水龙头上,注水头喇叭口压住被堵管道管口, 拧开自来水龙头,利用自来水本身的压力,就可在短时间内冲走管道中所堵杂物,使管道畅通。 When the inlet hose connected to the faucet, water injection head nozzle duct bellmouth pressed blocked, unscrew the tap, the pressure of tap itself, can be washed away in a short time as the pipeline blocked debris, the pipeline flow. 该管道疏通器存在一定缺陷,由于注水头喇叭口没有设置防回流结构,因此其在使用结束后,关闭水龙头,由于进水软管内部会形成一定的中空,管道内的污水会倒灌回流,进而污染水龙头,还有其不能使管道内的水容易排空,当我们将软管从管道内取出后,残留在软管内的水会溅出,污染地面,因此使用不安全卫生。 Some defects of the drain, a first bell mouth without water due to the backflow preventing structure is provided, so that after use, close the faucet, since the water inside the hose will be a certain hollow, water will flow backward in the reflux pipe, and further pollution faucets, as well as it can not make the water in the pipes easy emptying, when we removed the hose from the pipe remaining in the hose water splash, ground pollution, the use of unsafe health.

发明内容 SUMMARY

本实用新型所要解决的技术问题是针对上述现有技术现状而提供一种可有效防止污水回流、且能保证污水排除的用于管道疏通器的接头,该接头具有使用安全卫生、 结构简单合理的优点。 The utility model technical problem to be solved is for the above state of the prior art and to provide an effective sewage prevent reflux, and can ensure that the joint sewerage for pipeline dredge, which has a joint health and safety to use, simple and reasonable structure of advantage.

本实用新型解决上述技术问题所采用的技术方案为: 一种用于管道疏通器的接头,包括前端可与水龙头连接且具有贯穿通道的阀体,阀体内设有一具有凹腔的阔芯,其特征在于:所述的阀芯前部外表面与贯穿通道的前部内表面之间直接或间接液密封,所述的凹腔前端开口后端封闭,凹腔的侧壁上开有数个出水口,所述的阀体侧壁上开有数个进气孔,阀芯上还套设一由柔性材料制成且后端开口的弹性套,弹性套前端与阀芯相对固定,弹性套外表面与贯穿通道后部内表面之间具有间隙,在通水状态下,弹性套膨胀直接或间接将进气孔密封,在断水状态下,弹性套收縮将出水口密封,而进气孔与贯穿通道后部连通。 Aspect of the present invention to solve the above technical problem is: An adapter for Drain device comprising a valve body having a front end connected to the through-channel and the faucet valve body equipped with a die having a cavity width that characterized in that: a direct or indirect fluid tight seal between the outer surface of the front portion of the valve body and the inner surface of the front portion of the through passage, the rear end opening of the cavity is closed, is provided with several outlet on the sidewall of the cavity, the valve body sidewall opening last several inlet holes, the valve body sleeve is provided made of a further flexible material and the rear end opening of the resilient sleeve, an elastic sleeve fixed to the front end of the spool opposite, outer surface of the elastomeric sleeve through having a clearance between the inner surface of the rear portion of the channel, in the water passing state, the elastic expansion sleeve directly or indirectly into the seal hole, in a state without water, the shrinkage of the elastic sleeve sealed outlet, and into the through-hole and a rear passage . 为便于组装,增强接头装配的稳定性,上述的接头还包括一衬套,衬套套设在阀芯外部,衬套外端面的前部与后部均具有一凸肩,该两凸肩与贯穿通道内表面液密封,所述的阀芯外端面的前部具有凸肩,对应衬套内前部具有内肩胛,所述的弹性套前端的凸部被限位固定在阀芯上的凸肩与衬套上的内肩胛之间,所述的衬套侧壁上开有数个通气孔,弹性套外表面与衬套内表面之间具有间隙,在通水状态下,弹性套膨胀直接将通气孔密封,从而间接将进气孔密封。 The stability of ease of assembly, enhanced connector assembly, said connector further comprising a bushing, the bushing sleeve disposed outside the valve body, the front portion and the rear end surface of the outer sleeve has a shoulder, the shoulder and through two the inner channel surface of the liquid seal, the outer portion of the front end surface of the valve element has a shoulder, having a front portion corresponding to the inner liner scapula, said elastomeric sleeve distal convex portion is fixed to the shoulder stop on the spool between the shoulder blades and the liner, the liner on the side wall is provided with several vents, with a gap between the elastic sleeve and the inner surface of the outer liner surface, in the water passing state, through direct expansion of the elastic sleeve the pore-sealing, thereby indirectly the intake hole sealing. 衬套一般可采用塑料件,而阀体及阀芯为铜材料制成的,设置衬套作为过渡件还具有可使阀体相对做大,而阀芯及可相对做小,因此降低了生产成本。 Usually plastic liner may be employed, while the valve body and the valve body is made of a copper material is provided as a transition piece liner can also have a relatively bigger valve, and the valve body can be made relatively small, thus reducing the production cost. 为将弹性套更好的与阀芯相对固定,且增强阀体内部元件之间密封性,上述的弹性套前端的凸部和衬套的内肩胛之间还设有一垫圈密封。 The better is the elastic sleeve and the valve body is relatively fixed, and the inner element to enhance the sealing between the valve body further provided with a gasket seal between the shoulder blades and the convex portion of the liner elastic sleeve distal end. 为便于安装,上述的阀体内后部具有内肩胛,所述的衬套外端面后部的凸肩与所述的内肩胛相抵触。 For ease of installation, the valve body above the rear portion having an inner shoulders, the outer liner within scapula rear end surface of the projection and the conflict. 通过阀体上内肩胛与衬套上凸肩的配合,可提示我们衬套安装到位与否。 By mating shoulder on the upper body and shoulder blade bushing, you can prompt us bushing in place or not. 与现有技术相比,本实用新型的优点在于:使用时,阀体前端接水龙头,水从阀芯的出水口喷出,将弹性套撑大膨胀,进而将阀体上的进气孔直接或间接堵死达到密封的效果,这样水就会从通过贯穿通道后端喷出,进入管道疏通器内;当水龙头关闭时,弹性套收縮,将阀芯上的出水口封闭,而进气孔则与贯穿通道连通,水只受到重力及外界气压作用,往下回落,不会从阀芯的出水口倒灌到水龙头内,因此不会污染自来水,而且软管内不会残留脏水,有效避免残留在软管内的水会溅出,污染地面。 Compared with the prior art, the present invention is advantageous in that: when in use, then the front end of the faucet valve, water is discharged from the outlet of the valve body, the elastomeric sleeve expands stretch, and further holes on the intake valve direct blocked or indirectly to achieve the effect of sealing, so that water will be discharged from the rear end through the through passage, into the drain unit; when the faucet is closed, the elastic sleeve shrinking, the outlet valve element on the closure, and the intake port and through the passage, the water only by gravity and air pressure outside, fall down, can not flood the outlet from the valve body to the faucet, and therefore does not contaminate the water, and dirty water does not remain within the hose, avoid remaining in the hose water splash, contaminate the ground. 附图说明图l为本实用新型实施例的结构剖视图(断水状态); 图2为本实用新型实施例的结构剖视图(通水状态)。 FIG.
