Drawings
Fig. 1 is a schematic structural view of an improved soft seal gate valve according to an embodiment of the present invention.
Fig. 2 is a schematic view of the state of the gate valve when the gate valve is opened according to the embodiment of the present invention.
In the figure: the device comprises a hand wheel 1, a valve body 2, an upper cavity 3, a flow channel 4, a valve plate 5, a valve rod 6, a valve cover 7, a nut sleeve 8, a shell 9, a filter plate 10, an ultrasonic generator 11, a waste liquid port 12, a sealing cover 13, a first through groove 14 and a second through groove 15.
Detailed Description
The utility model will now be further described with reference to the accompanying drawings and specific embodiments.
The first embodiment is as follows:
referring to fig. 1, an improved soft seal gate valve disclosed in an embodiment of the present invention includes a valve body 2, a valve plate 5 and a valve rod 6, a flow passage 4 for water to flow through is provided in the valve body 2, a valve cover 7 is fixedly installed on the top of the valve body 2, a sealed upper chamber 3 is formed between the valve body 2 and the valve cover 7, a first through groove 14 is provided at a connection position of the upper chamber 3 and the flow passage 4, the valve plate 5 is longitudinally slidably disposed in the valve body 2 and can pass through the first through groove 14 to the upper chamber 3, two end surfaces of the valve body 2 and the valve plate 5 together form a sealing surface for blocking the flow passage 4, the hand wheel 1 is rotatably installed on the valve cover 7, the valve rod 6 is fixedly connected with the hand wheel 1, so that the hand wheel 1 drives the valve rod 6 to rotate synchronously, a nut sleeve 8 is fixedly installed on the valve plate 5, the nut sleeve 8 is in threaded connection with the valve rod 6, the valve plate 5 has a hollow structure for inserting the valve rod 6, when the hand wheel 1 drives the valve rod 6 to rotate, under the action of the nut sleeve 8, the valve plate 5 slides up and down to open and close the flow passage 4.
In this embodiment, a housing 9 is integrally formed at the bottom of the valve body 2, a sealed cavity is formed in the housing 9, a second through groove 15 for communicating the sealed cavity with the flow channel 4 is formed at the bottom of the valve body 2, a filter plate 10 is fixedly mounted at the bottom of the valve plate 5, the filter plate 10 passes through the second through groove 15, when the valve is closed, the filter plate 10 is accommodated in the sealed cavity of the housing 9, and the second through groove 15 is sealed by the bottom of the valve plate 5; when the valve is opened, as shown in fig. 2, the valve plate 5 is disposed in the upper chamber 3, the filter plate 10 is disposed in the flow channel 4, and when fluid flows in the flow channel 4, the filter plate 10 filters and removes impurities, and the impurities are intercepted and adhered to the filter plate 10.
