Description
Technical Field
The invention relates to an accessory on a floating roof tank, in particular to an automatic ventilation valve with adjustable height.
Background
The storage tank is an important device in an oil and gas gathering, transporting, storing and transporting system, and the crude oil storage tank is developing in large scale with the requirements of national crude oil strategic storage and energy safety, and the capacity of the crude oil storage tank reaches 15 multiplied by 104m at most3. Storage tanks are commonly used for storing volatile petroleum products such as crude oil, gasoline or kerosene, and are classified according to the structure of the tank top: the floating roof storage tank is divided into an outer floating roof storage tank and an inner floating roof storage tank. The large size (high volume) of the storage tank puts higher requirements on the design, manufacture and installation of the storage tank, and the floating roof is a sealing cover which is made of metal materials and floats on the surface of the liquid. The floating roof can float along with the rise and the fall of the liquid surface, and when the liquid surface falls to a certain height, the support column on the floating roof contacts the bottom plate of the tank, thereby supporting the floating roof to prevent the falling. The outer floating roof is provided with an automatic ventilation valve, when the floating roof is in a supporting state, the automatic ventilation valve is automatically opened, and air enters the floating disc to enable oil in the tank to be pumped out. On the contrary, when the floating roof is in a floating state, the automatic ventilation valve is automatically closed.
The existing automatic ventilation valve is generally shown in fig. 3 and mainly comprises a valve body, a valve rod and a valve cover. The valve body top is located to the valve gap, and the valve rod cover is located the valve body and is connected with the valve gap, floats the top and is in the supported state, and the valve rod is with valve gap jack-up, and the automatic breather valve of structure has following defect like this: after the valve cover is jacked up, the position of the valve rod is fixed, the height of the automatic ventilation valve is higher than that of the floating roof, namely the upper end of the surface of the oil product cannot be sealed, and if the storage tank still needs to keep the state within a period of time, the volatile oil product is evaporated and lost, and resources are wasted.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the height-adjustable automatic ventilation valve which is provided with the sleeve provided with the positioning hole, and the distance between the automatic ventilation valve and the bottom plate of the storage tank is changed by adjusting the height of the valve rod, so that the evaporation loss of oil products is effectively reduced, and the inspection and maintenance are not hindered.
In order to achieve the purpose, the invention adopts the technical scheme that:
the height-adjustable automatic ventilation valve comprises a valve body, a valve cover and a valve rod, wherein the valve cover is arranged at the top end of the valve body, the valve rod is sleeved in the valve body, a sleeve is arranged above the valve cover, a plurality of positioning holes are formed in the sleeve along the vertical direction, the valve rod penetrates through the valve cover and then extends out of the sleeve and is in sealing connection with the upper end of the sleeve through a sealing sleeve, and a pin hole which is matched and connected with the positioning holes is formed in the valve rod.
As preferred technical scheme, in order to effectively reduce oil evaporation loss and provide an operation space without hindering the storage tank inspection and maintenance, the positioning holes are provided with 4, and the mounting height of the lowest positioning hole is 1.2 m.
As an optimal technical scheme, in order to make the automatic ventilation valve be convenient for installation and transportation, avoid artifical transport, reduce the labour, improve the practicality, the top of valve rod is equipped with an apron, just be equipped with a lug on the apron.
Compared with the prior art, the invention has the following beneficial effects:
1. be equipped with the sleeve pipe of seting up the locating hole on the valve gap, through the position of adjusting valve rod and bushing, realize the change of automatic ventilation valve and storage tank bottom plate, effectively reduced the evaporation loss of oil on the one hand, avoided the wasting of resources, on the other hand also does not hinder the inspection maintenance.
2. The locating hole is provided with 4, and the mounting height of the lowest locating hole is 1.2m, further reduces oil evaporation loss, can provide sufficient operating space simultaneously, does not hinder storage tank inspection and maintenance.
3. The top of valve rod is equipped with an apron, just be equipped with a lug on the apron, make automatic ventilation valve be convenient for installation and transportation, avoid artifical transport, reduce the labour, the practicality is good.
