The fine adjusting type anti-blocking nozzle comprises a valve body and a valve core. The valve body is in a cylindrical shape, and an adjusting seat is arranged in the valve body. Conical adjusting holes are formed in the adjusting seat along the axial direction of the valve body in a penetrating mode, and large at the outside and small at the inside. Conical sealing heads matched with the adjusting holes in shape are arranged on the valve core. One end of the valve body is sealed, and a valve rod is arranged at one end of the valve body through threads. The inner end of the valve rod and the valve core are assembled together and can rotate relative to the valve core. An indicating sleeve is fixedly assembled on the valve rod and movably sleeved on the valve body. Indicating scales matched with the indicating sleeve are axially distributed on the outer wall face of the valve body. The fine adjusting type anti-blocking nozzle can be applied to a watering system in the petroleum exploiting process, and solves the problem that the watering system cannot adjust watering flow rate and blocking is prone to be caused.
Description
Technical field
The utility model relates to valve technology field, especially a kind of anti-blocking water nozzle of fine adjustment type that is used for petrochemical industry.
Background technology
At present, in the heavy oil production manufacturing process, because thermal recovery production is a kind of circulation, periodically exploitation.Notes vapour production each time all is the process of once annotating vapour-stewing well-oil flow production-mechanical oil recovery.Getting hold of each production link is the key that heavy oil production is produced.In moisture decline progressively, temperature reduces gradually, and under the situation that liquid measure also progressively descends, oil production is in rising trend, be lower than 20% moisture, temperature is lower than 40 ° of C, after, the crude oil fluidity of down-hole is variation progressively, and output descends gradually, flows to the shaft bottom until oil reservoir crude oil noenergy.For this round finishes.But directly cause the discharge pressure in the petroleum pipeline to become big because the flowability of low temperature, pure oil is too poor, directly influenced oil production.Effect is best is exactly that oil gathering station sewage returns and mixes companion's heat drop back pressure system, and it has made full use of the waste heat of Crude Oil Transportation process, has reduced the waste of effluent discharge, reduced back pressure, owing to the reduction of the pressure of conveying crude oil back, reduced the resistance of crude oil flow, improved the ability of oil transportation.But in the process that maximum problem is to use, existing water mixing system can't regulate and control the flow velocity of water mixing accurately, has some granule foreigns to stop up regulation and control water nozzles, causes regular obstruction, cleans very inconvenience, has brought very big labour intensity to maintenance work.
Summary of the invention
The purpose of this utility model is to provide a kind of fine adjustment type anti-blocking water nozzle, in the water mixing system that is used for the oil exploitation process, solves the water mixing system and can't regulate and control water mixing flow velocity and susceptible to plugging problem.
In order to address the above problem, the anti-blocking water nozzle of fine adjustment type of the present utility model is by the following technical solutions: the anti-blocking water nozzle of a kind of fine adjustment type, comprise valve body and spool, described valve body is cylindrical and wherein be equipped with adjustment seat, adjustment seat is provided with along the axial perforation of valve body, interior big outer little conical adjustment hole, has the cone seal head that coincide with the shape of adjustment hole on the spool, one end of valve body seals and by screw fit valve rod is arranged, the inner of this valve rod and spool are assembled together and can relative valve core rotation, fixedly be equipped with the indication cover on the valve rod, rotating being enclosed within on the valve body of indication cover is laid with and the indicating graduation of indicating cover to cooperate on the outside wall surface of described valve body vertically.
Also be provided with ball valve in the described valve body, ball valve comprises valve ball and valve seat, and valve seat is located at the inner port place of adjustment seat, and the cone seal head of valve ball and spool is made as one, and spool is connected with valve rod by valve ball.
The end that valve body cooperates with valve rod is equipped with valve gap, and valve rod is by being assemblied on the valve body with this valve gap threaded engagement.
Place, inboard at valve gap in the valve body is provided with the packing seal letter, and the corresponding end of valve body is by this packing seal letter sealing.
The outer end of described valve rod is equipped with adjusting handle.
Because the anti-blocking water nozzle of fine adjustment type of the present utility model is equipped with adjustment seat in its valve body, and adjustment seat be provided with along the axial perforation of valve body, interior big outside little conical adjustment hole, has the cone seal head that coincide with the shape of adjustment hole on the spool, one end of valve body seals and by screw fit valve rod is arranged, the inner of this valve rod and spool are assembled together and can relative valve core rotation, fixedly be equipped with the indication cover on the valve rod, rotating being enclosed within on the valve body of indication cover is laid with and the indicating graduation of indicating cover to cooperate on the outside wall surface of valve body vertically; Therefore, can come regulating spool moving on respective direction by rotating described valve rod in use, thereby regulate the gap between described cone seal section and the adjustment hole, thereby reach the purpose of control flow, in addition, because the existence of described indication cover and indicating graduation, can further increase the precision of Flow-rate adjustment, when in the valve body during residual obstruction, only need obstruction is washed away valve complete opening (reaching maximum) by fluid, therefore thereby also solved blockage problem, the anti-blocking water nozzle of fine adjustment type of the present utility model can be used for solving the water mixing system and can't regulating and control water mixing flow velocity and susceptible to plugging problem in the water mixing system in the oil exploitation process.
