Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gate valves, in particular to a parallel double-disc gate valve. Background Art
[0002] Double disc gate valve is a type of gate valve. Its structure and working principle are consistent with those of the gate valve. The opening and closing body (valve plate) is driven by the valve stem to move the valve seat sealing surface up and down, thereby connecting or cutting off the fluid channel.
[0003] The existing double-disc gate valve does not have a filtering function when in use. When there are more impurities in the water flow, the long-term accumulation can easily cause blockage inside the valve body. Therefore, in view of the above situation, there is an urgent need to develop a parallel double-disc gate valve with a filtering function, which can automatically clean the filter and is not easy to clog, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content
[0004] The purpose of the utility model is to provide a parallel double-disc gate valve to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A parallel double-disc gate valve, comprising a double-disc gate valve body, a flange, an impurity collection box, an impurity filter and a self-cleaning mechanism, wherein the impurity filter is fixed to the right end of the inner side of the double-disc gate valve body, the impurity collection box is fixed on the double-disc gate valve body below the impurity filter, the impurity filter is tilted, and the self-cleaning mechanism is installed in the double-disc gate valve body on the left side of the impurity filter. The self-cleaning mechanism comprises: a mounting sleeve, a rotating shaft, a water baffle, a knocking column and a tension spring, the mounting sleeve is fixed to the inner top end of the double-disc gate valve body, the rotating shaft extending to the outside of the mounting sleeve is rotatably connected, the water baffle is fixed to the lower side of the rotating shaft, the knocking column is fixed to the bottom of the water baffle, the knocking column is attached to the impurity filter, and a plurality of tension springs connected to the double-disc gate valve body are installed on the water baffle.
[0007] Preferably, a flange is fixed to both left and right ends of the double-disc gate valve body, and mounting holes for mounting bolts are provided on the flange.
[0008] Preferably, the impurity collecting box and the impurity filtering screen are both detachably fixed to the double-disc gate valve body by screws.
[0009] Preferably, the angle between the impurity filter and the horizontal plane is 60-70°.
[0010] Preferably, the impurity filter is made of stainless steel.
[0011] Preferably, the right end of the double-disc gate valve body is a water inlet, and the left end of the double-disc gate valve body is a water outlet.
[0012] The beneficial effects of the present invention are as follows: when the parallel double-disc gate valve is in use, water flows in from the right end of the double-disc gate valve body, and impurities in the water flow are filtered through the impurity filter. At the same time, when the water flows, it impacts the water baffle plate to deflect it to the left, so that the tension spring is stretched, and the knocking column is separated from the impurity filter. When the water is stopped, the impact force of the water flow disappears, and the water baffle plate returns to its position under the action of the elastic force of the tension spring. When the knocking column returns to its position driven by the water baffle plate, it will hit the impurity filter. The impurity filter generates vibrations under the action of the impact, and the impurities accumulated on the impurity filter are dropped off by the vibration, and the impurities are collected by the impurity collection box. In summary, the present invention has a filtering function, and can automatically clean the filter, and is not easy to be clogged. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Specific examples are given below.
[0021] See also Figures 1 to 4 , In the embodiment of the present invention, a parallel double-disc gate valve includes a double-disc gate valve body 1, a flange 2, an impurity collection box 3, an impurity filter 4 and a self-cleaning mechanism 5. The right end of the double-disc gate valve body 1 is a water inlet, and the left end of the double-disc gate valve body 1 is a water outlet. A flange 2 is fixed to both ends of the double-disc gate valve body 1. The flange 2 is provided with mounting holes 201 for mounting bolts. The arrangement of the flange 2 facilitates the connection of the double-disc gate valve body 1 to the external pipeline. An impurity filter 4 is fixed to the right end of the inner side of the double-disc gate valve body 1. An impurity collection box 3 is fixed to the double-disc gate valve body 1 below the impurity filter 4. The impurity collection box 3 and the impurity filter 4 are detachably fixed to the double-disc gate valve body 1 by screws. The impurity filter 4 is tilted, and the angle between the impurity filter 4 and the horizontal plane is 60-70 °, the impurity filter screen 4 is tilted to facilitate the impurities accumulated on the impurity filter screen 4 to fall downward, the impurity filter screen 4 is made of stainless steel, so that it has good corrosion resistance so that it can withstand the rust of impurities, the left side of the impurity filter screen 4 is installed with a self-cleaning mechanism 5 in the double-disc gate valve body 1, the self-cleaning mechanism 5 includes: a mounting sleeve 501, a rotating shaft 502, a water baffle 503, a knocking column 504 and a tension spring 505, the mounting sleeve 501 is fixed to the inner top of the double-disc gate valve body 1, the mounting sleeve 501 is rotatably connected to the rotating shaft 502 extending to its outside, the lower side of the rotating shaft 502 is fixed with a water baffle 503, the bottom of the water baffle 503 is fixed with a knocking column 504, the knocking column 504 is in contact with the impurity filter screen 4, and a plurality of tension springs 505 connected to the double-disc gate valve body 1 are installed on the water baffle 503.
[0022] Working principle: When the parallel double-disc gate valve is in use, water flows into the double-disc gate valve body 1 from the right end, and the impurities in the water flow are filtered through the impurity filter 4. At the same time, when the water flows, it will impact the water baffle 503 to make it deflect to the left, so that the tension spring 505 is stretched, and the knocking column 504 is separated from the impurity filter 4. When the water is stopped, the impact force of the water flow disappears, and the water baffle 503 returns to its original position under the action of the elastic force of the tension spring 505. When the knocking column 504 returns to its original position driven by the water baffle 503, it will hit the impurity filter 4. The impurity filter 4 vibrates under the action of the impact, and the impurities accumulated on the impurity filter 4 fall off through the action of the vibration, and the impurities are collected by the impurity collection box 3.
