Abstract
The utility model provides a well -flushing ooff valve, includes the center tube, the center tube outside is equipped with the connector be equipped with the spring between center tube and the connector in the space, the spring both sides are equipped with track sleeve and beginning sleeve respectively, are equipped with the connector in the connector in the track sleeve outside, beginning sleeve outer end is equipped with end cover, the outside lower end and connector cooperation of beginning sleeve, beneficial effect: this valve simple structure, case transposition is reliable, repeatedly usable, greatly reduced the cost, can also simplify subjob shaft bottom hole shutoff procedure down, reduce the operating cost, realize the area and press the rising of operation oil pipe stand, down, has guaranteed the area and has pressed the safety of operation, lightened the operation workman degree of difficulty of constructing, prevented effectively to lead to the fact environmental pollution to the well site, avoided the use well killing fluid to carry out the operation to pressure liquid has been eliminated to the potential destruction of payzone and the potential safety hazard of operation.
Description
Technical field
The utility model relates to mechanical equipment technical field, especially relates to a kind of well washing switch valve.
Background technology
Water source heat pump system because of its operating cost low, reliably energy-conservation, environment friendly and pollution-free obtaining is applied more and more widely.The pumped well of water resource heat pump and recharge well need to rotate at regular intervals, and namely pumped well becomes recharge well, recharge well becomes pumped well.Conventional solution arranges two pipelines in same well, and realized by the action of electrically operated valve and one way valve, the rotation of drawing water and recharging of same well, it is many that the method consumes material, and cost is high, and sealing effectiveness is poor, easily produces leakage.Also have in some mini-systems and manually carry pump, realize the rotation of pumped well and recharge well, the method manual physical labor measures greatly, is not suitable for frequent rotation.
Utility model content
For overcoming above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of well washing switch valve, comprise central tube, outside central tube, be provided with connector, it is characterized in that: between described central tube and connector, be provided with spring in space, spring both sides are respectively equipped with track sleeves and beginning sleeve, are provided with connector in the connector outside track sleeves; Beginning sleeve outer end is provided with end cap, and the lower end of beginning sleeve outside coordinates with connector.
Described track sleeves inner opposite end is connected by sunk screw and central tube.
Described connector and track sleeves matching surface are provided with track pin.
Described beginning sleeve is by O RunddichtringO and central tube fitted seal.
Described beginning sleeve is by O RunddichtringO and connector fitted seal.
Beneficial effect: this valve arrangement is simple, spool transposition is reliable, reusable, greatly reduces cost, endoporus shutoff program at the bottom of next well in operation can also be simplified, reduce operating cost, realize Operating Pressure oil pipe column rise, under, ensure that the safety of Operating Pressure, alleviate operating worker difficulty of construction, effectively prevent and environment pollution is caused to well site, avoid and use well killing fluid to carry out operation, thus eliminate the Latent destruction of pressure liquid for payzone and the potential safety hazard of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of well washing switch valve, comprises central tube 2, connector 7 is provided with outside central tube 2, between described central tube 2 and connector 7, be provided with spring 8 in space, spring 8 both sides are respectively equipped with track sleeves 3 and beginning sleeve 10, are provided with connector 1 in the connector 7 outside track sleeves 3; Beginning sleeve 10 outer end is provided with end cap 11, and the lower end 12 of beginning sleeve 10 outside coordinates with connector 7.
Described track sleeves 3 inner opposite end is connected by sunk screw 5 and central tube 2, improves stability.
Described connector 7 is provided with track pin 4 with track sleeves 3 matching surface, coordinates rationally, convenient fixing.
Described beginning sleeve 10 is by O RunddichtringO 9 and central tube 2 fitted seal, and good sealing effect, decreases the generation of leakage.
Described beginning sleeve 10 is by O RunddichtringO 13 and connector 7 fitted seal, and sealing rationally.
Operating principle is as follows:
Regulate two ends track sleeves and beginning sleeve by spring, thus regulate top connection and beginning sleeve, improve sealing effectiveness, reduce cost of production, decrease the generation of leakage.
