Description
Technical field
The utility model relates to technical field of hydraulic pressure, specifically a kind of pilot type shuttle valve.
Background technique
Test stand in modern manufacturing industry, in order to keep the up-to-standard rate of sample, needs frequent flushing test platform, makes it keep clean, in order to avoid affect new product sample.And washing test platform at present generally be with hydraulic system circulating picture-changing to method, the residual article in equipment are rinsed repeatedly by hydraulic fluid and are tackled by filter, thus the cleaning of proof test platform.Shuttle valve belongs to straight stroke valve, is that valve body and final controlling element unite two into one the valve of body.Its advantage volume is little, easy for installation, adds the particularity of internal piston structure, makes pressure medium almost not have more resistance to disturb to piston, thus realizes snap switch, the one's best quality that crushing is little.And the most important link of this hydraulic system is the working solution making flushing forward and backward isolates mutually, avoid element and the pipeline generation repeated contamination of rinsing forward and backward working solution approach.Shuttle valve like this plays vital effect in the process.Shuttle valve is the excellent design product that final controlling element and valve body unite two into one.Because valve body, piston, spool all adopt stainless steel, more attractive in appearance in appearance, high-grade, in actual use Sealing hardly with medium contact, there is more corrosion resistant feature, thus usage range is broader, adds inside and only have a parts (piston) in motion, make motion simple and reliable, life-span is long, even if maintenance is also more simple, and can install by any direction.In hydraulic system conventional at present, shuttle valve is all adopt solenoid valve to realize shuttle valve between different oil circuit, realize isolation, needs to carry out manual reverse of direction by external force, wastes time and energy, had a strong impact on the raising of working efficiency.Shuttle valve outward appearance is small and exquisite, compact structure, is convenient to maintenance, has again the gas pipeline control system of energy-conserving and environment-protective premium properties---QGES novel pneumatic quick opening valve, succeed in developing at Shen, Zhejiang instrument recently.Current this new product drops into small lot batch manufacture, and pays oil, chemical industry, metallurgical, and the clients such as air separation plant use.
In order to well solve the problem, the utility model provides a kind of pilot type shuttle valve.
Model utility content
The purpose of this utility model is to provide a kind of pilot type shuttle valve, by adopting valve body by steel ball 4, spring 5, spool 6 is formed, simple project organization as far as possible, meet quality lighter, the requirement of more compact structure, leading type sliding valve core, directly be screwed in valve opening by screw thread, use the removable spool of leading type, add mobility and flexibility, separate two chambeies to arrange, can seal separately, improve sealingly secure, shuttle valve wall is provided with spring and promotes steel ball simultaneously, make steel ball action more flexible, vent is used to bleed off unnecessary hydraulic pressure, can not because of the excessive damage shuttle valve of pressure.
The utility model solves the technological scheme that its technical problem adopts: a kind of pilot type shuttle valve, comprises shuttle valve body, it is characterized in that: described body interior is provided with valve body.
Described valve body is made up of steel ball 4, spring 5, spool 6.
Described spool 6 is leading type sliding valve core, is directly screwed in valve opening by screw thread.
Shuttle valve wall 7 is provided with in described body; Shuttle valve body is divided into two parts by shuttle valve wall 7; Shuttle valve wall 7 and steel ball 4 side are provided with and promote spring 8; Promote spring 8 to be connected with steel ball side, opposite side is fixed on shuttle valve wall.
Described body both sides side is respectively provided with a vent 9; Vent 9 is provided with internal thread and is provided with blockage body; Blockage body blocks vent.
The beneficial effects of the utility model are: 1, due to this pilot type shuttle valve, by adopting valve body by steel ball 4, spring 5, spool 6 is formed, simple project organization as far as possible, meet quality lighter, the requirement of more compact structure, leading type sliding valve core, directly be screwed in valve opening by screw thread, use the removable spool of leading type, add mobility and flexibility, separate two chambeies to arrange, can seal separately, improve sealingly secure, shuttle valve wall is provided with spring and promotes steel ball simultaneously, make steel ball action more flexible, vent is used to bleed off unnecessary hydraulic pressure, can not because of the excessive damage shuttle valve of pressure,
2, because described valve body is made up of steel ball 4, spring 5, spool 6.Simple project organization as far as possible, meets quality lighter, the requirement of more compact structure;
3, because described spool 6 is leading type sliding valve core, be directly screwed in valve opening by screw thread.Use the removable spool of leading type, add mobility and flexibility;
4, because shuttle valve body is divided into two parts by described shuttle valve wall 7; Shuttle valve wall 7 and steel ball 4 side are provided with and promote spring 8; Promote spring 8 to be connected with steel ball side, opposite side is fixed on shuttle valve wall.Separate two chambeies to arrange, can seal separately, improve sealingly secure, shuttle valve wall is provided with spring and promotes steel ball simultaneously, makes steel ball action more flexible;
5, because described body both sides side is respectively provided with a vent 9; Vent 9 is provided with internal thread and is provided with blockage body; Blockage body blocks vent.Vent is used to bleed off unnecessary hydraulic pressure, can not because of the excessive damage shuttle valve of pressure.
