Background technique
Proportional valve is widely used in sanitaryware, and its valve port can be opened a corresponding aperture as required, controls thus the size by flow.The present lifting along with the level of production, automatically controlled Proportional valve has substituted the Proportional valve of most of manual controls, existing Proportional valve includes adjustable lever, actuating motor and has water outlet and the valve body of water intake, the inner of adjustable lever is for the water outlet of shutoff valve body, and the outer end of adjustable lever is connected with the actuating motor being connected on valve body.Actuating motor drives adjustable lever to move axially along himself, thereby adjusts the aperture between the mouth of a river and the inner of adjustable lever, controls like this flow of water outlet.
In existing Proportional valve, adjustable lever is the monolithic construction that hard plastic material or metallic material are made, so the inner of adjustable lever and the water outlet of valve body are rigid contacting, while needing like this Proportional valve to close, the water outlet close contact of the inner of driven by servomotor adjustable lever and valve body, thereby sealing water outlet, yet in use, the inner of adjustable lever can directly be clamped in the water outlet of valve body under the effect of driven by servomotor power, cause stuck phenomenon, cannot realize again and regulating, must keep in repair or change, have short problem in working life.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of not fragile, adjustable lever in the Proportional valve of long service life.
The purpose of this utility model can realize by following technical proposal: adjustable lever in a kind of Proportional valve, comprise shaft-like body, it is characterized in that, the inner of described body is through being fixed with the block piece that stops that adjustment seat comes off on an adjustment seat and body, on described body, be arranged with and provide elastic force to make described adjustment seat be pressed in the spring of block piece, one end of described spring contacts at the step that body has, and the other end of spring contacts at adjustment seat.
In this Proportional valve, adjustable lever is arranged in the valve body of Proportional valve, the outer end of body is connected with actuating motor, while needing to close Proportional valve in using process, actuating motor drives body axial rotation, make the inner of body near water outlet, the water outlet of adjustment seat contact closed valve, so just, realized closing of Proportional valve, now actuating motor should quit work in time, when yet in reality, actuating motor quits work, existence because of inertia, the output shaft of actuating motor can be rotated further several angle, now body overcomes the elastic force of spring and with respect to adjustment seat axial motion, avoid like this adjustment seat to be clamped in water outlet, stop stuck phenomenon, this Proportional valve adjustable lever is in use not fragile, long service life, while needing to open Proportional valve afterwards, actuating motor drives body away from water outlet, spring reset, and adjustment seat is left water outlet with body.
In above-mentioned a kind of Proportional valve, in adjustable lever, between described adjustment seat and body, be provided with seal ring.Seal ring be arranged to there is good sealing between adjustment seat and body, during use, can not leak.
In above-mentioned a kind of Proportional valve in adjustable lever, the interior edge face of described adjustment seat has the annular groove snapping in for spring end, described adjustment seat has and is positioned at annular groove inboard and tubular extension part, described spring is placed on extension part outside, and described seal ring is between extension part and body.
As another kind of situation, in above-mentioned a kind of Proportional valve in adjustable lever, described adjustment seat has axially extended and tubular coated portion on the interior edge face of spring, and described step and spring are between coated portion and body, and described seal ring is between coated portion and body.
In above-mentioned a kind of Proportional valve, in adjustable lever, the exterior edge face of described adjustment seat is fixed with rubber ring.Actuating motor drives body to move axially, first rubber ring touches the water outlet of valve body, because rubber ring has elasticity, so there is certain buffering, can there is not rigid contacting, thereby guarantee that adjustment seat can not be clamped in the water outlet of valve body, guaranteed working life, rubber ring has improved sealing in addition, when Proportional valve cuts out, there will not be water leakage phenomenon, can reach throttling object.
In above-mentioned a kind of Proportional valve, in adjustable lever, described block piece is jump ring or bayonet lock.
Compared with prior art, this Proportional valve adjustable lever arranges by the split of body and adjustment seat, avoids adjustment seat to be clamped in water outlet, stop stuck phenomenon, in use not fragile, long service life, and the good airproof performance between adjustment seat and body, can not leak, further assurance adjustment seat is set can be clamped in water outlet of rubber ring, has also improved sealing, when Proportional valve cuts out in addition, there will not be water leakage phenomenon, can reach throttling object.
