Abstract
The utility model discloses a take pressure relief device's gate valve, including valve body, valve gap, hand wheel, valve rod, sealing washer, flashboard, spring, valve cover connection is on the valve body, the valve rod is installed at valve body center, and the hand wheel is installed at the top of valve rod, valve rod lower extreme and flashboard link to each other, and the valve rod lower extreme has a notch, can be in the flashboard free rotation to can drive the flashboard reciprocates, the flashboard transversely is equipped with inlet opening and apopore, installs the sealing washer in the middle of inlet opening and apopore, install the spring between valve rod bottom and the flashboard, it is ascending that the valve rod passes through the hand wheel rotation when opening the gate valve, and inlet opening and apopore intercommunication on the flashboard form the decompression passageway, reach the effect of decompression, and hand wheel continuation rotation valve is opened totally, the procedure is opposite when closing. The utility model has the advantages that the power of gate valve switch is little, convenient operation, can the seepage not appear after increasing the pore structure, can reach and effectively close rivers.
Description
Technical field
The utility model relates to a kind of gate valve, is specifically related to a kind of gate valve with decompressor.
Background technique
Current valve is on the market all single overall design, and the reason unlatching larger due to hydraulic pressure is extremely required great effort, and not easily opens, and to valve sealing face Fast Wearing, and gate valve sealing effect after closedown is bad, easy seepage.The pressure reducing mode generally adopted at present is bypass, but brings the wasting of resources, numerous and diverse problem of constructing, and wasting space, returns operation and bring inconvenience.
Model utility content
The purpose of this utility model solves above-mentioned deficiency, provides a kind of gate valve with decompressor.
For achieving the above object, technical solution of the present utility model is: a kind of gate valve with decompressor, comprises valve body, valve gap, handwheel, valve rod, seal ring, flashboard, spring; Described valve gap is connected on valve body, and described valve rod is arranged on valve body center, and the top of valve rod is provided with handwheel, and described valve rod lower end is connected with flashboard, and valve rod lower end, with notch, freely can be rotated in flashboard, and flashboard can be driven to move up and down; Described flashboard is laterally provided with water inlet and osculum, in the middle of water inlet and osculum, be provided with seal ring; Between described stem bottom and flashboard, spring is installed; When opening gate valve, valve rod is risen by hand wheel rotating, and the water inlet on flashboard is communicated with formation relief passage with osculum, reach the effect of decompression, handwheel is rotated further valve and opens completely; During closedown, program is contrary: when valve rod declines, and flashboard declines closed under the pressure of valve rod and the elastic force effect of spring, and after flashboard is completely closed, valve rod continues decline crush seal circle and water inlet is not communicated with osculum, and flow channel is closed completely.
The utility model has the following advantages: 1, flashboard intermediate hole plays decompression, reaches the effect of smooth laborsaving Open valve, flashboard osculum and water inlet intermediate arrangement seal ring, can not occur seepage, can reach and effectively close current because of increase vent; 2, flashboard existing closedown when stem bottom mounting spring can make to close, then paddle hole is closed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve body, 2-valve gap, 3-handwheel, 4-valve rod, 601-water inlet, 602-osculum, 5-seal ring, 6-flashboard, 7-spring.
Embodiment
As shown in Figure 1, a kind of gate valve with decompressor, comprises valve body 1, valve gap 2, handwheel 3, valve rod 4, seal ring 5, flashboard 6, spring 7; Described valve gap 2 is connected to valve body 1 top, described valve rod 4 is arranged on the center of valve body 1 and valve gap 2, valve rod 4 is connected by square threaded form with valve gap 2, the top of valve rod 4 is fixed with handwheel 3, described valve rod 4 lower end is connected with flashboard 6, described valve rod 4 lower end, with notch, freely can be rotated in flashboard 6, and flashboard 6 can be driven to move up and down; Described flashboard 6 is laterally provided with water inlet 601 and osculum 602, in the middle of water inlet 601 and osculum 602, be provided with seal ring 5; Bottom described valve rod 4 and between flashboard 6, spring 7 is installed; When opening gate valve, valve rod 4 is rotated by handwheel 3 and rises, and the water inlet 601 on flashboard 6 is communicated with formation relief passage with osculum 602, reach the effect of decompression, handwheel 3 is rotated further valve and opens completely; When closing gate valve, valve rod 4 declines, flashboard 6 declines closed under the pressure of valve rod 4 and the elastic force effect of spring 7, after flashboard 6 is completely closed, valve rod 4 continues decline crush seal circle 5 and water inlet 601 is not communicated with osculum 602, and flow channel is closed completely.Play decompression by the intermediate hole of flashboard 6, reach the effect of smooth laborsaving Open valve, the osculum 601 of flashboard 6 and water inlet 602 intermediate arrangement seal ring 7, seepage can not be occurred because of after increase hole structure, can reach and effectively close current.
