Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is a sectional view of the flow regulating valve provided by the embodiment of the present invention. Such as figure 1 As shown, the flow regulating valve includes: a valve body 1 , a main valve 2 , a slave valve 3 , a first plug 4 and a second plug 5 .

[0036] Wherein, the valve body 1 is a cuboid, and the valve body 1 includes a main valve chamber 101, a slave valve chamber 102 and a connecting chamber 103. Wherein, the main valve cavity 101 is a cylindrical cavity with the same diameter, and the slave valve cavity 102 is a conical cavity with a variable diameter, and the diameter of the upper valve cavity of the slave valve cavity 102 is larger than that of the slave valve cavity 102 bottom. The diameter of th...

Abstract

The invention discloses a flow rate regulation-control valve, and belongs to the technical field of valves. The flow rate regulation-control valve comprises a valve body, a master valve, a slave valve, a first screwed plug and a second screwed plug. When flow rate control is carried out through the flow rate regulation-control valve, a non-straight water flow channel is formed by a master valve cavity, a slave valve cavity, and a connection cavity for communicating the master valve cavity with the slave valve cavity, and therefore, water flow is subjected to force relief and water distributionwhile flowing through the water flow channel, then the impact force of the water flow on a master valve element and a slave valve element is reduced, the wear and the torsion of the master valve element and the slave valve element are reduced, the service life of the master valve element and the slave valve element is prolonged, the opening-closing torque of the master valve is reduced, and automatic control can be better realized.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a flow control valve. Background technique [0002] Water flooding is an important method of oil recovery in oilfields. When water injection starts, the flow control valve can be opened to allow water to enter the pipeline, and when water injection is finished, the flow control valve can be closed to block the water flow. Moreover, in order to ensure that the amount of water injected meets the relevant requirements, the amount of water injected can be adjusted through a flow control valve. [0003] At present, the commonly used flow regulating valve in water injection operation is the cone valve. Wherein, the water flow channel of the cone valve is a straight-through type, and when water is injected, the water flow directly flows from the input port of the cone valve to the output port of the cone valve through the straight-through water flow channel. When performing flow contro...
