Abstract
The utility model discloses a kind of energy-saving counterbalance valve, valve element is provided with valve body, valve element latus rectum 20mm, valve body are provided with dust-proof seal ring with valve element junction, spring are provided with valve element, spring is connected with spring socket sleeve, spring socket sleeve is connected with stainless steel filter screen, and stainless steel filter screen is connected by pad with pretension bolt, and the utility model reduces liquid resistance of the liquid in pipeline, the loss of pump energy is reduced, reduces just useful cost.
Description
Technical field
Utility model is related to a kind of energy-saving counterbalance valve, belongs to counterbalance valve technical field.
Background technology
Technical scheme：To achieve the above object, the utility model provides a kind of energy-saving counterbalance valve, including valve
Body, valve element, spring, dust-proof seal ring, spring socket sleeve, stainless steel filter screen, pad, pretension bolt, valve body is interior to be provided with valve element, valve
Core latus rectum 20mm, valve body are provided with dust-proof seal ring with valve element junction, spring are provided with valve element, and spring is connected with spring socket sleeve,
Spring socket sleeve is connected with stainless steel filter screen, and stainless steel filter screen is connected by pad with pretension bolt, and the utility model reduces
Liquid resistance of the liquid in pipeline, reduces the loss of pump energy, reduces just useful cost.
Oil-field oil pumper stablizes the pressure and flow of oil well outlet, oil nozzle front end using the oil nozzle of fixed throttle port at present
Inlet pressure is the geostatic pressure of pump, generally between 1.5-2.5MPa by restriction after, depressurization is obvious, i.e. the oil nozzle
In tower generally between 0.4-0.6MPa, this pressure be oil well fuel transfer pressure, due to fixed throttle port oil nozzle latus rectum not with
Import step pressure, flow change and change, cause that well head pressure loss in part is excessive, and the larger pressure loss causes oil pump
The larger energy loss of squad, increase cost for oil production, therefore design a kind of counterbalance valve, reduce its resistance of liquid in pipeline, reduce
The loss of pump energy.
Utility model content
Purpose of utility model：The larger energy loss of oil pump squad is caused in order to overcome to exist in the prior art, increase is adopted
The problem of oily cost, the utility model provide a kind of energy-saving counterbalance valve.
Brief description of the drawings
Fig. 1 is the structural representation of the energy-saving counterbalance valve of the present embodiment；
In figure：Valve body -1, valve element -2, spring -3, dust-proof seal ring -4, spring socket sleeve -5, stainless steel filter screen -6, pad
Piece -6, pretension bolt -8.
Embodiment
It is further elaborated below in conjunction with accompanying drawing and by specific embodiment to the utility model, it should be pointed out that：For this
For the those of ordinary skill of technical field, on the premise of the utility model principle is not departed from, to of the present utility model various
The modification of the equivalent form of value falls within the application appended claims limited range.
Embodiment 1：
A kind of energy-saving counterbalance valve as shown in Figure 1, including valve body 1, valve element 2, spring 3, dust-proof seal ring 4, spring
Cover for seat 5, stainless steel filter screen 6, pad 7, pretension bolt 8, the valve body 1 is interior to be provided with valve element 2, the latus rectum 20mm of valve element 2, institute
State valve body 1 and be provided with dust-proof seal ring with the junction of valve element 2, spring 3, the spring and 3 spring socket sleeves 5 are provided with the valve element 2
Connection, the spring socket sleeve 5 are connected with stainless steel filter screen 6, and the stainless steel filter screen 6 is connected by pad 7 and pretension bolt 8
Connect, the utility model reduces liquid resistance of the liquid in pipeline, reduces the loss of pump energy, reduces just useful cost.
