Description

Flow control valve

Technical field

The utility model relates to a kind of valve of Flow-rate adjustment.

Background technique

Valve is widely used in workers and peasants' production.Valve commonly used mainly is the pipeline cut-off valve, as butterfly valve and gate valve, mainly is that flowing liquid in the pipeline is controlled.The shortcoming of above-mentioned valve is in the time need regulating the flow of ducted liquid, can not satisfy the accurately requirement of control of Flow-rate adjustment.

The model utility content

The purpose of this utility model is exactly to solve valve to be difficult to provide a kind of flow control valve to the accurate problem of regulating of flow.

The technical solution adopted in the utility model is: flow control valve, it is characterized in that it comprises the tubular valve body, is fixed in the deflector, filter cylinder and the filter cylinder mobile gear that take the shape of the letter U in the valve body, described deflector opening direction is consistent with valve body water outlet direction, the piston cylinder that is provided with liquid sealing with it in the deflector opening and can moves forward and backward along deflector opening inwall, piston cylinder is shifted out can be to the valve outlet fluid-tight; Filter cylinder is fixed in the end of piston cylinder; Described filter cylinder is the cylindrical shell at the bottom of the end band, and barrel is provided with the plurality of rows through hole; The rotating shaft of described filter cylinder mobile gear bag, cam and rocking bar, valve body and deflector are crossed in rotating shaft, two ends are actively connected on the valve body wall, one end stretches out valve body, cam is positioned at deflector and is fixed in the rotating shaft, the piston cylinder front end is connected with the piston collar, and the rocking bar two ends flexibly connect with cam and piston collar respectively.

Adopt technique scheme, liquid flows into from valve body one end, when needs are closed, rotating shaft, cam will move with valve interior wall by rocking bar driven plunger tube and cooperate the realization valve body to close, when regulating flow, the backward rotation rotating shaft, cam will spur piston cylinder by rocking bar and move to the inside, and filter cylinder stretches into, liquid promptly can flow out by the through hole on the filter cylinder, compile from the outlet of valve body again and flow out, distribute because the through hole on the piston cylinder is rule, the control characteristic of piston cylinder trends towards linearly adjust like this, the flow and the valve opening that are it are linearly proportional, thereby realize accurate flow adjustment.

For reaching better rectification effect, the bottom of described filter cylinder is provided with the V-shaped cowling in outside protrusion cross section.

In sum, the beneficial effects of the utility model are: because the control characteristic of the utility model piston cylinder trends towards linearly adjust, promptly its flow and valve opening are linearly proportional, so the utility model can be realized accurate flow adjustment.

Embodiment

The utility model flow control valve, as shown in Figure 1, it comprises tubular valve body 1, is fixed in the deflector 3, filter cylinder 7 and the filter cylinder mobile gear that take the shape of the letter U in the valve body 1.

As shown in Figure 1, deflector 3 is fixed on the central authorities of valve body 1 by several floors 13.Deflector 3 opening directions are consistent with valve body 1 water outlet direction, are provided with in deflector 3 openings with it by water conservancy diversion seal ring 11 and realize liquid sealings and the piston cylinder 6 that can move forward and backward along deflector 3 opening inwalls, and piston cylinder 6 is shifted out can be to valve body 1 outlet fluid-tight.Present embodiment is achieved in that as shown in Figure 1, is fixed with valve seals 10 on the inwall at the water outlet place of valve body 1, the right part of piston cylinder 6 is fixed with the seal ring 18 that cooperates with it, when piston cylinder 6 moved to right, the extruding of two seal rings can realize liquid sealing.

As shown in Figure 1, filter cylinder 7 is fixed in the end of piston cylinder 6, and filter cylinder 7 is the cylindrical shell at the bottom of the end band, and barrel is provided with the through hole 8 that plurality of rows is gathered.The bottom of filter cylinder 7 is fixed with the V-shaped cowling 9 in outside protrusion cross section.

The filter cylinder mobile gear comprises rotating shaft 14, cam 2 and rocking bar 5, and valve body 1 and deflector 3 are crossed in rotating shaft 14, and two ends are actively connected on valve body 1 wall by bearing.Rotating shaft 14 1 ends stretch out valve body 1, apply torque when easy to use.Cam 2 is positioned at deflector 3 and is fixed in the rotating shaft 14 by key 19, and piston cylinder 6 front ends are connected with piston collar 12, and rocking bar 5 two ends flexibly connect by bearing pin 4 and cam 2 and piston collar 12 respectively.

Install for convenient, the bottom of described deflector 3 is and deflector 3 separable deflector bonnets 16 to be tightly connected with deflector 3 by rubber seal 17 and gland 15.
