Abstract

The invention discloses a well washing switch valve which comprises a central pipe. The outer side of the central pipe is provided with a connecting body, a spring is arranged in a space formed between the central pipe and the connecting body, the two sides of the spring are provided with a track sleeve barrel and a beginning sleeve barrel respectively, and the portion, on the outer side of the track sleeve barrel, of the connecting body is provided with a connector; the outer end of the beginning sleeve barrel is provided with an end cover, and a lower end head outside the beginning sleeve barrel is matched with the connecting body. The well washing switch valve has the beneficial effects that the structure is simple, valve core position replacing is reliable, reusing is achieved, and the cost is greatly lowered; in addition, the downhole inner hole blocking procedure of next operation can be simplified, the operation cost is lowered, lifting and falling of an oil pipe stand column in operation under the pressure are achieved, the safety of the operation under the pressure is guaranteed, the construction difficulty of operation workers is relieved, environmental pollution is effectively prevented from being caused to a well site, kill fluid is prevented from being used for the operation, and therefore the potential destruction of the kill fluid to a production layer and the operation potential safety hazards are eliminated.

Description

Well washing switch valve
Technical field
The present invention relates to mechanical equipment technical field, especially relate 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.
Summary of the invention
For overcoming above-mentioned technical problem, the technical solution used in the present invention 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 invention.
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.
