Abstract
The invention discloses a butterfly valve service life testing machine, belongs to a testing device, and particularly relates to a device used for testing the service life of a butterfly valve. The butterfly valve service life testing machine is characterized in that the butterfly valve service life testing machine comprises a water supply system used for testing, a butterfly valve fixing and driving device and a PLC control system, rectangular valve body fixing frames which are parallel to each other are installed on a base of the butterfly valve fixing and driving device, an inverted-L-shaped pneumatic head support is installed at the position, located at one end of each rectangular valve body fixing frame, of the base, a pneumatic head is fixed onto a supporting plate of the pneumatic head support, and a connecting rod connected with a test butterfly valve is installed below the pneumatic head. The butterfly valve service life testing machine can realize the circulation of automatic stamping-pressure maintaining-butterfly valve opening-butterfly valve closing-secondary stamping. A single cycle can just simulate the use process of the butterfly valve. Meanwhile, the butterfly valve service life testing machine can further realize the effects that the stamping pressure is adjustable, the pressure maintaining time is adjustable and automatic counting can be achieved. By means of the butterfly valve service life testing machine, after the butterfly valve is installed in place and all parameters are well adjusted, the service life test of the butterfly valve can be completed automatically. Thus, the butterfly valve service life testing machine is convenient and quick to use and capable of saving time and labor.
Description
Technical field
The invention belongs to a kind of testing equipment, particularly test the butterfly valve equipment in serviceable life.
Background technology
Butterfly valve is a kind of variable valve simple in structure, refers to that closing member (flap or butterfly plate) is disk, rotates to reach a kind of valve of open and close around valve shaft, and the utilization scope of butterfly valve is wider, and the switch that can be used for low pressure pipeline medium is controlled.Butterfly valve is not only used widely on the general industries such as oil, coal gas, chemical industry, water treatment, but also is applied to the cooling water system of thermo-power station.
According to butterfly valve Valuation Standard < < butterfly valve static pressure durability test rules JB/T8863 > >, requirement, under laboratory condition, valve is being subject to pressure medium to do the used time, carries out the test of the cycling from standard-sized sheet to complete shut-down.Valve must be done the durability test of 1000 open and close circulation.Still be not suitable at present the butterfly valve life test equipment that R&D and production enterprise is used.A lot of units are used the method for artificial controlled valve to carry out durability test, need continuous working just can complete for several days, and labour intensity is large, the time is long.
Summary of the invention
In order to overcome existing manual control switch's valve, carry out the deficiency of butterfly valve durability test, the invention provides a kind of butterfly valve life test machine, this butterfly valve life test machine carries out butterfly valve durability test automatically according to programming.
The technical solution adopted for the present invention to solve the technical problems is: a kind of butterfly valve life test machine, it is characterized in that: comprise test water system, butterfly valve is fixed and driving arrangement and PLC control system, on the base of the fixing and driving arrangement of described butterfly valve, the rectangle valve body fixed mount being parallel to each other is installed, the vertical scuncheon of valve body fixed mount is provided with sliding tray, the lower V-arrangement clamping plate of opening upwards and the upper V-arrangement clamping plate that Open Side Down are installed in groove, the V-arrangement clamping plate clamping screw that lower end connects upper V-arrangement clamping plate is housed in the middle of valve body fixed mount upper side frame, in the middle of the clamping plate of V-arrangement up and down of two valve body fixed mounts, be installed be equipped with water inlet or water delivering orifice to folder flange, the pneumatic head bracket of inverted L-shaped is housed on the base of rectangle valve body fixed mount one end, pneumatic head is fixed on the supporting plate of pneumatic head bracket, be equipped with and the connecting link of testing butterfly valve and being connected pneumatic head below.
On the feed pipe of described test with the connection experimental facilities water under high pressure import of water system, booster water pump, voltage stabilizing water pot, high-pressure check valve, electro connecting pressure gauge, water under high pressure inlet pressure gauge are housed successively, the return pipe being connected on test butterfly valve water delivering orifice is once equipped with water delivering orifice tensimeter, Electrocontrolled high-pressure non-return valve.
Described PLC control system comprises that the signal input part of programmable controller, controller is connecting electro connecting pressure gauge, and signal output part is connecting booster water pump switch, pneumatic gauge tap, automatically controlled non-return valve.
The invention has the beneficial effects as follows---pressurize---the circulation of punching press again that butterfly valve leaves---butterfly valve pass---that can realize automatic press of this equipment.The use procedure of butterfly valve is just simulated in single circulation.Simultaneously this equipment can also realize that stamping pressure is adjustable, the dwell time is adjustable and Auto-counting.This equipment is in place butterfly valve, after parameters mixes up, can automatically complete the durability test of butterfly valve, convenient and swift, time saving and energy saving.
