Abstract
The utility model discloses a pump head of an automobile chemical feeder for an oil well. The pump head comprises a connecting body, a connector, a check ring, a pressure cap, a plunger rod, a pump head cap, a pump head pressure cap, a pump head body, a plunger valve, a valve seat and a valve cover. The connecting body is connected with the pump head body; the connector, the pressure cap, the plunger rod, the pump head cap and the pump head pressure cap are installed in the pump head body in sequence; and the plunger valve, the valve seat and the valve cover are installed at the outer end part of the pump head body. The oil well automobile chemical feeder pump head is characterized in that the pump head prevents clogging, leakage and airlock, can process different types of chemical and perform various chemical feeding modes, such as pipeline chemical feeding, well top chemical feeding, sleeve chemical feeding and the like, does not need a specially-assigned person to take care of, has low rated input power, small, compact and reasonable volume, convenience of installation and maintenance, easiness of operation, low cost, and the like, and can be widely applied to petroleum extraction wells and similar situations.
Description
Technical field
The utility model relates to petroleum production oil well medicine adding device, particularly a kind of oil well automatic medicament feeding machine pump head.
Background technique
Existing a kind of petroleum production well medicine feeding machine dosing pump pump head, be the single valve structure, the dosing pump of this dosing pump head is that the dosing of petroleum production well also is that the oil production technology in oil field has been brought into play effect, but this medicine feeding machine dosing pump pump head exists following shortcoming or deficiency: 1. single valve structure, be difficult for sealing gas-liquid during the filling medicament, easily produce leakage, gas lock phenomenon; 2. adding dose can not guarantee, so influence oil well output; 3. efficient is low; 4. easily produce well liquid during dosing and pour in down a chimney phenomenon to the pump head, at this moment must open pump head and clean, repair, often incur loss through delay the dosing cycle of well, influence the ordinary production of well.
Summary of the invention
Order of the present utility model provides a kind of oil well automatic medicament feeding machine pump head, adopts double-valve type structure up and down, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art, guarantee oil well on time, normal dosing according to quantity.
Oil well automatic medicament feeding machine pump head described in the utility model comprises connecting body, connecting head, back-up ring, pressure cap, plunger rod, pump head cap, pump head pressure cap, pump head body, plunger valve, valve seat, valve gap.Described connecting body is connected with pump head body, and connecting head, pressure cap, plunger rod, pump head cap, pump head pressure cap are installed in the pump head body in turn, and the outer end of pump head body is equipped with plunger valve, valve seat and valve gap.
Wherein, outer four of described plunger valve is Yi Bian install two symmetrically.Described plunger valve comprises valve seat, valve ball and the valve gap that is installed in the plunger valve.Described pressure cap is installed on the periphery of connecting head.The outer end of described connecting head is equipped with back-up ring.
The utility model has following advantage compared with prior art:
1, anti-plugging, lost circulation prevention, anti-gas lock can add dissimilar medicaments and carry out multiple dosing methods such as pipeline dosing, well head dosing and sleeve pipe dosing;
2, do not need the special messenger to keep an eye on, only need to observe medicament liquid level in the chemical tank, regularly add medicament;
3, rated input power is little, has only 100W, and hi-lo circuit all can use;
4, little, the compact and reasonable of volume, be convenient to I﹠M, easy to operate, cost is low.
Description of drawings
Accompanying drawing is a kind of example structure schematic representation of the present utility model.
