Abstract
The utility model discloses a unidirectional-control precise throttle valve which mainly comprises a body, a precise adjusting rod, an adjusting nut base, a nut and a hexagon nut. The precise adjusting rod penetrates through the adjusting nut base to be inserted in the body and is fixed through a pin, the adjusting nut base and the hexagon nut are fixed with the body through threads, the nut is connected with the precise adjusting rod through threads, a Y-shaped ring is arranged between the lower end of the precise adjusting rod and the body, an O-shaped ring is arranged between the precise adjusting rod and the adjusting nut base, an O-shaped ring is arranged between the adjusting nut base and the body, an air inlet is arranged at one end of the body, and the other end of the body is provided with an air outlet. By means of a precise adjusting assembly composed of the precise adjusting rod and the adjusting nut base, requirements for being higher in adjusting precision and adjusting precision stability and larger in flow are met compared with products in the prior art. Adjusting precision is stable through locating and locking of the nut, all parts are all connected through threads, an application range is wide, and the valve is not easy to be affected by environment. Simultaneously, the unidirectional-control precise throttle valve is simple in structure, simple in manufacture process and low in cost.
Description
Technical field
The utility model belongs to pneumatic antomation Equipment Control field, the accurate throttle valve of especially a kind of unidirectional control.
Background technique
Throttle valve in the market is of a great variety, but degree of regulation generally is not very stable, and easily affected by environment and cause using inconvenient, and such as low temperature, high temperature corrosion environment etc., general throttle valve complex structure, complex manufacturing technology, cost is high.
The model utility content
To the deficiency that exists in the existing technology, the purpose of the utility model is to provide a kind of degree of regulation stable, be difficult for affected by environment and simple in structure, the simple accurate throttle valve of unidirectional control with low cost of preparation process.
The utility model adopts following technological scheme to realize its purpose: the accurate throttle valve of a kind of unidirectional control; Mainly comprise body, fine adjustment bar, adjusting nut seat, nut and hexagon nut; It is characterized in that: the fine adjustment bar passes the adjusting nut seat and is inserted in the body, and fixes through mortise pin, and the adjusting nut seat is in the same place through screw thread and body-fixed with hexagon nut; Nut links to each other with the fine adjustment bar through screw thread; Be provided with Y-shaped ring between fine adjustment bar lower end and the body, be provided with O type circle between fine adjustment bar and the adjusting nut seat, be provided with O type circle between adjusting nut seat and the body; Body one end is provided with suction port, and the other end is provided with the air outlet.
The beneficial effect that the technological scheme that adopts the utility model to provide can reach is: the fine adjustment assembly that the utility model is formed through fine adjustment bar and adjusting nut seat, realized than prior art products degree of regulation accuracy, degree of regulation stability, the requirement that flow is big; Then through the nut positioning and locking; O type circle and Y-shaped ring make good airproof performance, and each component are all through being threaded, and are applied widely; Be difficult for affected by environment; The utility model is simple in structure simultaneously, and preparation process is simple, and cost is low.
