Abstract
An automatic dewatering device for storage tanks is used for dewatering of the storage tanks storing liquid with specific gravity lower than that of water. The automatic dewatering device consists of a cylinder, a float and a valve, wherein the float is arranged in the cylinder and the valve is welded on a flange at the opening of a pipeline connected with a lower seal head of the cylinder. The automatic dewatering device is characterized in that the lower end of the float is connected with a valve shaft of the valve via a lever. When in implement, the distance from the lever fulcrum to the joint point of the lower end of the float and the lever is much larger than the distance from the lever fulcrum to the joint point of the lever and the valve shaft, buoyancy of the float is magnified by the lever so that the valve is easy to be opened to drain and closed. Compared with the existing automatic dewatering device for storage tanks, the automatic dewatering device has the advantages of light structure, low material consumption and manufacturing cost and the like. In addition, volumes of the cylinder and the float are 1/3 of those of an original cylinder and an original float.
Description
Affiliated technical field
The utility model relates to a kind of moisture trap, particularly relates to the moisture trap of the energy automatic dehydration of using on a kind of storage tank, uses for the storage tank dehydration of depositing the proportion liquid littler than water.
Technical background
At present the automatic dehydration device of using on the storage tank all is the bottom that valve is contained in the moisture trap cylindrical shell, the lower end of float directly and the valve shaft of valve link, when water in the cylindrical shell seldom the time, the gravity pressure of leaning on float on axle with valve closing.When in the cylindrical shell water being arranged, water floats float, the valve shaft of float pulling valve emits valve open to water, the weak point of this automatic dehydration device is that cylindrical shell and float must could be opened valve with the valve shaft pull-up of valve very greatly, otherwise float is little and buoyancy is also little, then can not draw valve shaft and the valve of not opening, can not play the effect of automatic dehydration, thereby cause the structure heaviness, consumptive material is many, the cost height.
The utility model content
The purpose of this utility model is to overcome the automatic dehydration device structure heaviness that present storage tank is used, and consumptive material is many, and the weak point that cost is high provides a kind of structure light and handy, and consumptive material is economized, the automatic storage tank dewatering device that cost is low.
The purpose of this utility model is achieved through the following technical solutions, the automatic storage tank dewatering device is by cylindrical shell, and float and valve are formed, and float is contained in the cylindrical shell, valve is welded in low head with cylindrical shell and links on the flange of pipeline opening, links with lever between the lower end of float and the valve shaft of valve.
The automatic dehydration device of using on the utility model and the present storage tank is compared, link with lever between valve shaft because of the lower end of float and valve, the buoyancy of float amplifies doubly a lot through lever, so the cylindrical shell of automatic storage tank dewatering device and float can be done for a short time than originally, thereby it is light and handy to have structure, consumptive material is economized, the advantage that cost is low.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of at present used automatic storage tank dewatering device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawing: 1---feed pipe; 2---the end socket on the cylindrical shell; 3---blow-down pipe; 4---cylindrical shell; 5---float; 6---lever; 7---the balance pivot bar; 8---valve; 9---coolant outlet pipe; 10---valve shaft; 11---the low head on the cylindrical shell; 12---the emptying pipe; 13---support foot; The fulcrum of A---lever 6 and balance pivot bar 7; B---lever 6 links a little with float 5 lower extreme points; C---lever 6 links a little with valve shaft 10.During enforcement, the welding of float 5 usefulness sheet materials is made, lever 6 usefulness sheet materials are made, AB should be a lot of doubly greater than AC, valve 8 and original the same, and the used material of all the other parts is the same with former used material, but the size of cylindrical shell 4 and float 5 only is original about 1/3, so structure is light and handy, consumptive material significantly reduces, and cost is also low certainly.
During use, the dehydrated mouth of feed pipe 1 and storage tank is linked.What the storage tank dehydrated mouth was discharged mainly is water, also is being mingled with the proportion liquid of depositing in the storage tank littler than water certainly, as wet goods, owing to water than great, so water below, above the liquid storage in the little storage tank of proportion then floats over.When material constantly enters from feed pipe 1, at this moment float 5 lifts the left end of lever 6 constantly toward come-up, makes the A point clickwise of lever 6 on fulcrum bar 7, valve shaft 10 past Zolas, valve 8 is opened and is discharged water.Along with water is constantly emitted and water level reduces, float 5 constantly down, the left end of lever 6 also constantly down makes the A point left-hand revolution of lever 6 on fulcrum bar 7, valve shaft 10 is turned right to be pushed away, and valve 8 is closed.So move in circles, realize automatic dehydration.
