Description

A kind of self-closing valve under water-supply off

The utility model relates to a kind of supply channel auxiliary device, exactly is a kind of self-closing valve under water-supply off.

In existing indoor supply channel, also lack and a kind ofly can be used in combination the device that plays the water-stopping self-closing effect with ordinary faucet, so in daily life, people are in case forget when cutting off the water and close water tap, when supplying water so once more, the phenomenon of will metalling run out, waste water resource not only, but also cause damage for easily people's property.

The purpose of this utility model is for people provide a kind of self-closing valve under water-supply off that can match with ordinary faucet, so that overcome the deficiencies in the prior art.

The purpose of this utility model is to realize like this, it is provided with a threeway, the horizontal pipeline section in both sides, this threeway vertical pipeline section lower end constitutes water inlet segment and draining pipeline section respectively, water inlet segment chamber internal fixation is installed baffle ring, vertical pipeline section, fixedly mount respectively in the draining pipeline section chamber ring body shape on, lower valve base, encapsulation can be free movable in three cavities between baffle ring and the described valve seat, proportion is less than on the water proportion, lower valve ball, when water tap is in opening state, on, lower valve ball under by the hydraulic action in three cavities respectively with described on, form liquid sealing between the lower valve base, on being somebody's turn to do, lower valve ball diameter sum is greater than described each pipeline section intracavity diameter, and the difference of the depth dimensions of lower valve ball insertion lower valve base is greater than the distance between this valve seat and the baffle ring opposing end surface under this diameter sum and the sealing state; Valve gap that has openable sealing dewatering orifice of vertical pipeline section upper end sealed attachment, depression bar that the top valve ball can be pushed into lower limit position under external force of sealing activity plug-in mounting in the body of valve gap upper end.

The utility model compared with prior art has the following advantages after realizing: 1, when it connects use with water tap, in case forget when cutting off the water and close water tap, when feeding water so once more, upper and lower valve ball just can amplexiform with the inner sphere of upper and lower valve seat respectively under the fluid pressure effect mutually, form sealing, thus the generation of the phenomenon of avoiding metalling run out.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Fig. 1 is the utility model structural representation.

As seen from the figure, the utility model is provided with a threeway of adopting copper material to make, and the horizontal pipeline section of both sides, this threeway vertical pipeline section lower end constitutes water inlet segment 15, draining pipeline section 10 respectively, and this inlet pipe, drain pipe section outside nose end all is shaped on and connects screw thread 8; Fixed installation baffle ring 14 in the water inlet segment inner chamber, this baffle ring adopts plastic materials to make, and its diameter of bore is fixedly connected between its cylindrical and this pipeline section inner chamber less than valve ball 6 and valve ball 7 diameters, this concrete grammar that is fixedly connected can be that interference fit connects, and also can be that cementation connects; The draining pipeline section, fixedly mount lower valve base 9, the upper valve base 5 of ring bodies in the vertical pipeline section chamber respectively, wherein, lower valve base 9 adopts plastic materials to make, its inboard nose end promptly illustrates the right side nose end and is shaped on the sphere that matches with lower valve ball 7, be fixedly connected between this valve seat cylindrical and the draining pipeline section inner chamber, this concrete grammar that is fixedly connected can be that interference fit connects equally, also can be that cementation connects; Upper valve base 5 adopts rubber material to make, its inboard nose end promptly illustrates the downside nose end and is shaped on the sphere that matches with upper valve ball 6, be fixedly connected between this valve seat and the vertical pipeline section inner chamber, concrete joining method is: elasticity is located and is contacted between upper valve base cylindrical and the pipeline section inner chamber, simultaneously, promptly illustrate the thrust ring 4 that upper end fixed installation adopts metallic material to make at the upper valve base outboard end, scyewed joint between the endoporus on this thrust ring and the vertical pipeline section, and to valve seat 5 formation axial stop; Encapsulation can be free movable in three cavities between baffle ring 14, lower valve base 9, upper valve base 5, proportion is less than the upper and lower valve ball 6,7 of the proportion of water, when water tap is in opening state, upper and lower valve ball can amplexiform with upper valve base 5, lower valve base 9 medial extremity spheres respectively under by the hydraulic action in three cavities mutually, forms liquid sealing.When upper and lower valve ball is set, also make both diameter sums greater than each pipeline section intracavity diameter of threeway and when making this diameter sum and sealing state lower valve ball insert the difference of depth dimensions of lower valve base greater than the distance between this valve seat and the baffle ring opposing end surface, to guarantee that in the two valve ball contact processes, the top valve ball can be crimped on the valve ball of bottom all the time; The valve gap 3 that connects a sealing in vertical pipeline section upper end by threaded connection mode, be shaped on a dewatering orifice on this valve gap, pass through to connect screw thread 11, rubber washer 12 on this end, dewatering orifice hole wall cylindrical, end cap 13 of sealed attachment detachably, be shaped on the guiding connecting hole on the valve gap 3 upper end bodies, seal versatilely by connecting hole and seal ring 2 depression bar 1, this depression bar that adopts nylon material to make of plug-in mounting can be pushed into lower limit position with top valve ball 6 under the external force effect of upper end.

Above-mentioned mode of execution of the present utility model is not unique, for example, the first, the material of manufacturing of threeway can also be a hard plastics; The second, upper valve base also can adopt plastic materials to make; The 3rd, the material of manufacturing of valve gap and adapted end cap thereof also can be a hard plastics.

Use installation method of the present utility model is, water inlet segment 15 connects screw thread by pipe end and connects with the supply channel end sealing, and draining pipeline section 10 is by pipe thread and water tap sealed attachment.

Working principle of the present utility model is: under the water tap opening state, when feeding water once more after cutting off the water, upper and lower valve ball 6,7 amplexiforms with the medial extremity sphere of upper and lower valve seat 5,9 respectively under hydraulic action mutually, form liquid sealing, make water promptly can not enter water tap by draining pipeline section endoporus of the present utility model, can not leak by the utility model itself, play the water-stopping self-closing effect; When people need pass through the water tap water, can close water tap in advance, open end cap 13 again, the dewatering orifice of valve gap 3 is opened, then, press moulded rod 1 downwards, the upper valve ball 6 and the sealing together of upper valve base 5 are unlocked, water in three cavities is discharged through the dewatering orifice of valve gap, and the intraluminal pressure in lower valve ball 7 tops this moment moment reduces, and causes this valve ball to break away from lower valve base 9, upwards float with the water level rising, and enter in the vertical tube section chamber, make to seal between the two to be unlocked, remove the external force that puts on the depression bar this moment, then make upper valve ball return under hydraulic action, and and upper valve base between form sealing again, water can not be leaked by the utility model, the tap of fetching boiling water again is an available water.
