Abstract

The utility model relates to a valve, in particular to an angle seat valve capable of controlling the flow rate, the pressure and the temperature in a pipeline and recording and storing an implementation process. The technical scheme of the angle seat valve lies in that the angle seat valve is characterized by comprising a control mechanism, a pneumatic executing mechanism and a valve body, wherein the pneumatic executing mechanism comprises an air pressure cavity body, a piston, a spring and a piston rod; the spring is arranged at the upper side of the piston, and the air pressure cavity is arranged at the lower side of the piston; the piston is moved up and down under the pressure action of the spring and the air pressure cavity; the end part of a telescopic elastic part is hermetically arranged on the valve body through a compaction block to ensure that the top end of the piston rod is hermetically surrounded by a flexible valve element; and the valve element is matched with a valve seat of the valve body to realize flow control. Due to the adaptation of the scheme, the utility model overcomes the defects of the prior art and provides a novel angle seat valve which has good performance and can be used for realizing the automatic regulation and control of the valve open degree.

Description

A kind of angle pedestal valve

Technical field

This is practical newly to relate to a kind of valve, be meant especially its can controlling plumbing fixtures in the angle pedestal valve of flow, pressure and temperature and implementation process record retention.

Background technique

Existing valve all is manually operated basically, so on the automated production equipment line, be difficult to coupling, the existence of some intelligent control valves is arranged also in addition; But these intelligent control valve complex structures; Move not quietly, function singleness is so also have significant limitation.

Summary of the invention

This practical new purpose is to overcome the deficiency that existing technology exists, and provides a kind of performance good, can realize the novel angle pedestal valve of automatic adjusting control valve door open degree.

In order to realize above purpose, the following technological scheme of this practical new employing: a kind of angle pedestal valve is characterized in that: include control mechanism, pneumatic actuator and valve body; Said pneumatic actuator includes air pressure cavity, piston, spring and piston rod; Its medi-spring and piston are arranged in the air pressure cavity, and piston rod is fixed on the piston, and said spring is arranged on the upside of piston; The underside gas pressure chamber of piston; Piston is realized moving up and down under the pressure effect of spring and gas pressure chamber, and said piston rod becomes oblique setting with liquid passage in the valve body, and the top of said piston rod is provided with compact heap and flexible spool; Flexible spool comprises valve core and telescopic resilience portion; Valve core and telescopic resilience portion are wholely set, and the end of said telescopic resilience portion is arranged on through the compact heap sealing and constitutes flexible spool on the valve body and the top of piston rod is formed sealed packet enclose and put, and said valve core cooperates the realization flow control with the valve seat of valve body.

Adopt such scheme, we make process control membrane valve complete function, particularly can have the function of the open degree of autocontrol valve, and overall structure is simple in addition.

The further setting of the utility model is: said control mechanism includes process controller, positioning work piece, position detecting device, sensor, solenoid valve and tracheae; Wherein position detecting device is connected on the positioning work piece; Sensor is connected on the process controller; Process controller is connected on the positioning work piece, and solenoid valve is controlled by positioning work piece; Described solenoid valve is provided with two groups, they all with the air pressure cavity of pneumatic actuator on the turnover tracheae be connected the wherein air inlet of one group of electromagnetic valve turnover tracheae, the giving vent to anger of another group electromagnetic valve turnover tracheae.

Through the scheme of further setting, product all can have performance, particularly control mechanism preferably to adopt such scheme on function and effect, and effect is very desirable, and control flow rate is accurate.

Below in conjunction with accompanying drawing to this practical new work further explain.
