Description

Novel gate valve

Technical Field

The utility model belongs to the technical field of valves, and relates to a gate valve, in particular to a novel gate valve.

Background

The gate valve is a shutter, the moving direction of the shutter is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled.

In order to ensure the tightness of the gate valve, sealing rings are arranged at a plurality of positions in the gate valve, the existing gate valve is simple in structure, and when high-pressure water impacts the gate valve, the high-pressure water is not effectively buffered, so that mechanical components in the gate valve are damaged, and particularly the sealing rings are easily damaged, and the overall service performance is affected.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a novel gate valve with a buffering function.

The aim of the utility model can be achieved by the following technical scheme: the novel gate valve comprises a valve body with a water inlet end, and is characterized in that a flange water inlet pipeline is externally connected to the water inlet end, and a buffer structure for buffering high-pressure water is arranged in the flange water inlet pipeline;

the buffer structure constitute by the buffer board that two symmetries set up, be arranged in connecting two buffer boards the pipe box and be located two fixed plates at two buffer board rear, well pipe box top have the opening, and this buffer structure has still included the rigid coupling on the flange inlet channel and stretched into the fixed pipe that in the pipe box link to each other with well pipe box, two the fixed plate all weld on well pipe box and support between corresponding buffer board and be connected with the spring, buffer board articulated cooperation in on well pipe box.

In the novel gate valve, the middle pipe sleeve is provided with the shaft sleeve for the buffer plate to be matched and installed, the upper end and the lower end of the buffer plate are respectively provided with the connecting seat, and the connecting seats are hinged and matched on the shaft sleeve through the connecting shaft.

In the novel gate valve, the fixing plate and the corresponding buffer plate are respectively provided with the spring hooks, and two ends of the spring are respectively fixed on the spring hooks.

In the novel gate valve, the fixed pipe is in threaded connection in the middle pipe sleeve.

Compared with the prior art, the novel gate valve has the advantages of good buffering effect and improved overall service performance.

Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1, fig. 2, fig. 3, this novel gate valve, including the valve body 2 that has water inlet end 1, water inlet end 1 department external flange inlet channel 3, flange inlet tube is equipped with the buffer structure that carries out the buffering to high-pressure water in to, buffer structure comprises the buffer plate 4 of two symmetries setting, be arranged in connecting the well pipe box 5 of two buffer plates 4 and be located two fixed plates 6 at two buffer plate 4 rear, well pipe box 5 top has the opening, and this buffer structure has still included the rigid coupling on flange inlet channel 3 and stretches into the fixed pipe 7 that in pipe box 5 links to each other with well pipe box 5, two fixed plates 6 all weld on well pipe box 5 and with corresponding buffer plate 4 between the support be connected with spring 8, buffer plate 4 articulates the cooperation on well pipe box 5, when rivers are washed, the buffer plate 4 of two articulated settings inwards radially overturns under the support of spring 8, can slow down rivers impact force greatly, noise reduction.

Further, the middle pipe sleeve 5 is provided with a shaft sleeve 9 for the buffer plate 4 to be matched and installed, the upper end and the lower end of the buffer plate 4 are respectively provided with a connecting seat 10, and the connecting seats 10 are hinged and matched on the shaft sleeve 9 through connecting shafts 11, so that the effect of radial movement of the buffer plate 4 is achieved.

Preferably, the fixing plate 6 and the corresponding buffer plate 4 are respectively provided with a spring hook 12, and two ends of the spring 8 are respectively fixed on the spring hooks 12.

Further, the fixing pipe 7 is in threaded connection with the middle pipe sleeve 5, the flange water inlet pipe 3 is taken out, the installation of the buffer structure is facilitated, the buffer plate 4 is assembled on the middle pipe sleeve 5, the middle pipe sleeve 5 is placed into the flange water inlet pipe 3, then the fixing pipe 7 is inserted into the flange water inlet pipe 3, the fixing pipe 7 is in threaded connection with the middle pipe sleeve 5, and then the fixing pipe is fixed on the flange water inlet pipe 3 through a nut, so that the installation is completed.
