Description
Technical field
This utility model relates to control valve, specifically refer to a kind of strengthen on a pipeline of valve body or reduce pressure control
The valve that another pipeline is turned on and off, the control valve i.e. controlled based on pressure medium.
Background technology
The existing control valve controlled based on pressure medium is also commonly referred to as four-sided valve, is the hydraulic pressure control by a water route, road
The special valve of another water route, road break-make, due to this characteristic, is widely used in water purifier now, can be according to water purifier pure water
The hydraulic pressure of water side controls the break-make in water purifier former water water inlet end water route.In prior art, traditional four-sided valve fills at valve body
There is diaphragm, utilize two-way pressure difference to control what another pipeline was turned on and off；This structure is in the feelings of water pressure circle critical point
Under condition, when closing valve, diaphragm unit there will be shake, produces noise.
Utility model content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art to exist, and provides a kind of structure design
Rationally, the control valve controlled based on pressure medium of operating noise can effectively be reduced.
For achieving the above object, the technical solution of the utility model is the tool including being made up of main valve body and pressure source valve body
Having the shell of plunger shaft, seal sliding and be provided with piston in described plunger shaft, plunger shaft is separated into pressure by described piston
Source chamber and action chamber, described pressure source valve body is provided with at least one medium pressure passage, on described pressure source valve body
It is provided with the pressure hole of connection pressure passage and pressure source chamber, described main valve body is provided with the medium being sequentially communicated and enters logical
Road, connection chamber and medium passing away；Described connection chamber seal isolation is arranged at outside action chamber；
Described piston links relative to the side in action chamber and arranges universal driving shaft, and the head end of this universal driving shaft is provided with and is placed in connection
The sealing cap of intracavity, this sealing cap enters passage with medium and seals adaptation, described action corresponding to connecting side, the chamber port of export
Intracavity is additionally provided with elastic reaction in the piston reset spring of piston, the force direction of this piston reset spring and piston pressurized
The active force of power source chamber is contrary.
Arrange further be described main valve body and pressure source valve body solid relative to being provided with between connection chamber and action chamber
Due to the isolation lid of outer casing inner wall, isolation covers the universal driving shaft sliding being provided with piston and seals adaptive linkage axle sleeve.
Arrange further be described piston reset spring be compression spring, the two ends of this compression spring elastic reaction respectively
It is connected to piston and isolation covers.
Arrange further be the medium pressure passage of described pressure source valve body by the pressure intake channel being sequentially communicated, execute
Pressure center-aisle and pressure exit passageway are constituted, and described pressure hole is connected setting with the center-aisle that presses.
Principle and advantage of the present utility model is: when on pressure source valve body, the pressure of medium pressure passage strengthens, medium
Pressure enters into pressure source chamber by pressure hole, thus drives piston to move down and block medium entrance passage and connect between chamber
Connected state, thus the medium of main valve body is entered passage and the disconnection of medium passing away；Otherwise, when medium on pressure source valve body
When the pressure of pressure passage is less, piston resets under the effect of piston reset spring, and medium entrance passage turns on connecting chamber,
This structure is owing to there being the buffering of spring to reset, and without diaphragm membrane, therefore switch motion is steady, and will not produce shake and make an uproar
Mail is inscribed.
Below in conjunction with specification drawings and specific embodiments, this utility model is described further.
Accompanying drawing explanation
Fig. 1 this utility model detailed description of the invention sectional view.
