Detailed Description
The existing valve is subjected to double anti-blocking operation through the clamping of the external thread on the plunger and the internal thread of the water outlet pipe and the blocking of the plunger, and the sealing mode has some defects: if the valve is used on a pipeline through which hot water flows, the piston is easy to deform after long-time thermal expansion and contraction, and the threads of the plunger and the water outlet pipe are easy to wear after long-time use, so that the situation of loose clamping is caused, and the valve is also in a water leakage condition under a closed state.
Example 1: as shown in fig. 1-4, the device includes a valve body 1, a screw 11 is screwed in the valve body 1, a sealing element 12 for sealing a water outlet is connected to the lower end of the screw 11, a first sealing component is arranged on one side, close to the water inlet, of the interior of the valve body 1, and a second sealing component is arranged on one side, close to the water outlet, of the interior of the valve body 1, wherein:
when the screw 11 rotates to drive the sealing element 12 to descend to seal the valve body 1, the sealing element 12 drives the first sealing component to descend to seal the water inlet, and meanwhile, the second sealing component is pressed downwards by the sealing element 12 to seal the water outlet; the upward movement of the sealing member 12 causes the first sealing assembly to follow the upward movement to open the water inlet, while the second sealing assembly elastically and upwardly filters the water flow entering the valve body 1
Firstly, a specific structure of a first sealing assembly is disclosed, the first sealing assembly comprises a first elastic piece 21 connected inside a valve body 1, the lower end of the first elastic piece 21 is connected with the upper side of a first sealing plate 2, the lower side of the first sealing plate 2 is attached to the lower side of a sealing piece 12, when a screw 11 is rotated, the screw 11 is connected with the valve body 1 through threads, so that the screw 11 descends with the sealing piece 12 to close the valve body 1, the sealing piece 12 pushes the first sealing plate 2 to descend together in the descending process, at the moment, the first sealing plate 2 stretches the first elastic piece 21, so that the first sealing plate 2 can be quickly reset after the sealing piece 12 leaves, after the first sealing plate 2 is pushed down to the lower end of the valve body 1 by the sealing piece 12, the first sealing plate 2 seals the part of the valve body 1 close to a water inlet, and the sealing effect of the sealing piece 12 is assisted.
According to the above, since the valve body 1 is sealed by the seal 12 and the first sealing plate 2, the portion to be sealed needs to be matched with the size of the seal 12, and therefore, the first deflector 13 is provided at the portion near the water inlet inside the valve body 1, the second deflector 14 is provided at the portion near the water outlet inside the valve body 1, and the gap between the first deflector 13 and the second deflector 14 can allow water flow to pass through, and is convenient for sealing.
In addition, a chute 22 is formed on one side of the first sealing plate 2, and a slider on one side of the first deflector 13 slides inside the chute 22, so that the first sealing plate 2 is kept stable from the influence of water flow when moving up and down.
Example 2: when the first sealing plate 2 and the sealing member 12 intercept the water flow, the water flow having flown through may leak through the other side of the sealing member 12, so in order to enhance the leakage-proof effect, a specific structure of the second sealing assembly is disclosed: the second sealing assembly comprises a limiting plate 3 positioned at the lower side of the inner part of the valve body 1, a limiting groove is formed in one side of the limiting plate 3, a second elastic piece 32 is arranged in the limiting groove, a second sealing plate 31 is connected to the upper side of the second elastic piece 32, and one side of the second sealing plate 31 is attached to one side of the second guide plate 14;
when the sealing element 12 descends, the second sealing plate 31 is extruded through the protruding portion at one side of the sealing element 12, so that the second sealing plate 31 slides downwards into the limiting groove formed in the limiting plate 3 and extrudes the second elastic element 32, and therefore the sealing portion of the second sealing plate 31 is located at the position of the valve body 1 close to the water outlet for three-layer sealing, and water leakage is prevented in an omnibearing manner.
Example 3: because the arc carries some solid impurity in the rivers under most circumstances, when rivers pass through valve body 1, if not filter the impurity, can influence the people who uses the rivers, consequently a plurality of filtration holes 33 have been seted up to the position that is close to the middle part on second closing plate 31, the interval looks adaptation between the area of seting up of filtration hole 33 and first guide plate 13 to the second guide plate 14, the filtration hole 33 is located the position that rivers passed through under the condition that valve body 1 was opened, can filter the impurity of rivers inside, guarantees people's healthy water.
To sum up, the working principle of the scheme is as follows: when the screw 11 is rotated, the screw 11 is connected with the valve body 1 through threads, so that the screw 11 drives the sealing element 12 to descend to close the valve body 1, the sealing element 12 pushes the first sealing plate 2 to descend together in the descending process, at the same time, the first sealing plate 2 stretches the first elastic element 21, after the first sealing plate 2 is pushed down to the lower end of the valve body 1 by the sealing element 12, the first sealing plate 2 seals the part of the valve body 1 close to the water inlet, meanwhile, in the descending process of the sealing element 12, the second sealing plate 31 is extruded through the protruding part at one side of the sealing element 12, so that the second sealing plate 31 slides downwards into a limiting groove formed in the limiting plate 3 and extrudes the second elastic element 32, and therefore, the part of the second sealing plate 31 for sealing is positioned at the part of the valve body 1 close to the water outlet to perform three-layer sealing, and all-around water flow leakage is prevented;
when the screw 11 rotates reversely to enable the sealing element 12 to rise to open the valve body 1, after the sealing element 12 leaves the first sealing plate 2, the first elastic element 21 loses force to enable the first sealing plate 2 to reset, the sealing element 12 does not squeeze the second sealing plate 31 any more, the second elastic element 32 loses force to enable the second sealing plate 31 to slide upwards in the limit groove formed in the limit plate 3, and therefore the filtering holes 33 are located at the gap between the first guide plate 13 and the second guide plate 14 to filter water flow.
The first elastic member 21 and the second elastic member 32 are preferably metal springs or the like, which are suitable for the prior art.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed.
