Abstract
The utility model provides a pressure control device, in particular to an anti-corrosive safety valve used for a booster pump. The anti-corrosive safety valve used for the booster pump has a valve body with a valve cavity, wherein a pressure inlet pipe is arranged on the side wall of the valve body; the upper part of the valve body is communicated with a pressure relief pipe; a valve core is installed inside the pressure relief pipe; a pressure spring is arranged on the upper part of the valve core; a pressure relief hole is formed in the side wall of the pressure relief pipe; the anti-corrosive safety valve of the booster pump is characterized in that an oil cup is installed on the lower part of the valve body; and the oil cup is communicated with the valve cavity. By adopting the structure, the anti-corrosive safety valve used for the booster pump is simple in structure and convenient to use; and the oil cup is filled with engine oil and the engine oil is added into the valve core under the action of water, so that the safety valve can be effectively protected from corrosion, the service life of the safety valve is prolonged, and the production cost of oil extraction is reduced.
Description
Technical field
The utility model provides a kind of pressure control device, especially a kind of corrosion protection safety valve that is used for suction booster.
Background technique
In oil-field flooding operation, suction booster is the most frequently used a kind of water injection equipment, in order to keep the water injection pressure maintenance than pressure stable, safety valve is installed on suction booster in the injecting process.When the pressure in the suction booster surpassed the force value of setting, safety valve can be opened pressure release automatically to reduce pressure; When the pressure in the suction booster during less than the force value set, safety valve is in closed condition.Because water quality that safety valve contacted is relatively poor and have stronger corrosivity, the spool of safety valve is immersed in for a long time and is easy to be corroded in such water and damages, cause the sealability of safety valve to reduce at last, need often to change safety valve, so not only increased cost of production but also influenced ordinary production.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of technological scheme that is used for the corrosion protection safety valve of suction booster at the deficiencies in the prior art, and this technological scheme can effectively prevent the safety valve corrosion, reaches to improve the safety valve purpose in working life.
The utility model is to realize like this, a kind of corrosion protection safety valve that is used for suction booster, the valve body that it has the band valve pocket is equipped with the entrance pressure pipe on the body wall, valve body top is communicated with relief tube, spool is installed in the relief tube, pressure spring is equipped with on spool top, and the relief tube sidewall is provided with relief hole, it is characterized in that, valve body lower portion is equipped with lubricating cup, and described lubricating cup is connected with valve pocket.
Drain valve also is housed on the sidewall of described valve body.
The beneficial effect of model utility: the corrosion protection safety valve that is used for suction booster that adopts said structure, simple in structure, utilization convenience, machine oil is housed in the lubricating cup, machine oil is filled into the spool place under the effect of water, can prevent effectively that safety valve from being corroded, prolong the working life of safety valve, reduced the oil recovery cost of production.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure.
Wherein, 1-entrance pressure pipe, 2-valve pocket, 3-pressure spring, 4-relief tube, 5-relief hole, 6-spool, 7-valve body, 8-drain valve, 9-lubricating cup.
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further.
As shown in the figure, a kind of corrosion protection safety valve that is used for suction booster of the present utility model, the valve body 7 that it has band valve pocket 2 is equipped with entrance pressure pipe 1 on valve body 7 sidewalls, and valve body 7 tops are communicated with relief tube 4, spool 6 is installed in the relief tube 4, pressure spring 3 is equipped with on spool 6 tops, and relief tube 4 sidewalls are provided with relief hole 5, it is characterized in that, valve body 7 bottoms are equipped with lubricating cup 9, and described lubricating cup 9 is connected with valve pocket 2; Drain valve 8 also is housed on the sidewall of described valve body 7.
When using the utility model, entrance pressure pipe 1 is connected with suction booster, load onto machine oil in the lubricating cup 9, because the density of water is bigger than the density of oil, water when work in the valve pocket 2 can enter in the lubricating cup 9 to be replaced out with the machine oil in the lubricating cup 9, machine oil can on float to relief tube 4 places spool 6 wrapped up, avoided contacting of spool 6 and water, play the effect that prevents spool 6 corrosion.When the mud or the grains of sand are arranged in the utility model, open drain valve 8 mud or the grains of sand are discharged, can improve sealing of the present utility model like this.Pressure release principle of the present utility model is not described in detail in this with existing safety valve working principle.The utility model is simple in structure, can prevent effectively that safety valve is subjected to the corrosion of sewage, improves the working life of safety valve.
Claims (2)
1. corrosion protection safety valve that is used for suction booster, it has the valve body of band valve pocket, the entrance pressure pipe is housed on the body wall, valve body top is communicated with relief tube, and spool is installed in the relief tube, and pressure spring is equipped with on spool top, the relief tube sidewall is provided with relief hole, it is characterized in that valve body lower portion is equipped with lubricating cup, described lubricating cup is connected with valve pocket.
2. a kind of corrosion protection safety valve that is used for suction booster according to claim 1 is characterized in that, drain valve also is housed on the sidewall of described valve body.
