Abstract

The utility model provides a timing closing valve which is composed of a valve body, a valve rod, a valve plug, an upper spring, a lower spring, a sealing ring, and a screw plug. An inner valve rod, the valve plug, the upper spring, the lower spring, and the sealing ring are fixed in the valve body through the screw plug, and the upper end of the valve rod is connected with the timer. The utility model with the characteristics of reasonable design, simple structure, easy processing, small size, easy use, etc. can be used for the timing conveyance of liquids and gases with infinite quantities on special pipes.

Description

Timing closing valve

The utility model relates to a kind of valve, specifically a kind of timing closing valve with timer.

On the pipeline of carrying liquid, gas, all want the quantity delivered of mounted valve in order to controlling liquid gas, at present, the various valves that are used for control gaseous, liquid conveying are a lot, have electronic, pneumatic and manual or the like, but on relevant document, also publish or product public use aborning arranged with the timing closing valve of timer.

The purpose of this utility model provides the limit the quantity of timing closing valve of conveyance fluid of a kind of timing with timer.

The purpose of this utility model realizes in the following manner, in valve body, establish the valve plug of band valve rod, valve plug places the valve pocket of valve body, and valve pocket is located in the middle of the duct chamber, and the upper end of valve rod and the driving cam of timer join, during use, rotate the knob of timer, knob drives driving cam, and driving cam promotion valve rod moves down valve plug is opened, gas or flow of liquid are crossed valve pocket, and duct chamber is open-minded.After timer starts, backward rotation under the effect of the clockwork spring of driving cam in timer, valve rod moves along the track of driving cam, and timer is to regularly at the end, and valve rod resets under the spring action of stem bottom and duct chamber is ended valve closing.

Accompanying drawing 1 is the cross section structure schematic representation of timing closing valve;

Accompanying drawing 2 is the end-face structure schematic representation of timing closing valve.

Explain below with reference to Figure of description timing closing valve of the present utility model being done.

Timing closing valve of the present utility model, its structure be by valve body 1, valve rod 2, valve plug 3, Upper spring 4, lower spring 5, sealing ring 6 and plug 7 consist of, plug 7 with inner valve stem 2, Valve plug 3, upper spring 4, lower spring 5, sealing ring 6 are fixed among the valve body 1, valve rod 2 The upper end joins with timer 8.

The bottom of valve body 1 is a duct chamber 9, the centre of duct chamber 9 is provided with valve pocket 10, valve plug 3 is positioned among the valve pocket 10, the top of the lower end of valve rod 2 and valve plug 3 joins, lower spring 5 is fixed between the bottom of plug 7 and valve plug 3, upper spring 4 is fixed between the top and seal ring 6 of valve plug 3, and seal ring 6 is located between timer 8 and the valve body 1.

The roof anchorage of valve rod 2 has a pulley 11 and the driving cam 12 of timer 8 to join, and driving cam 12 is fixed on the live axle 13 of conventional machinery formula timer 8.

Embodiment:

Its processing and fabricating of timing closing valve of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Valve body, valve rod, plug can with nylon, engineering plastics or metallic material routinely machining make, timer is with common mechanical timer, just the drive plate with original driving switch contact is processed into the cam-like driving cam, the pulley at itself and valve rod top is joined get final product, pulley moves the just switching of may command valve plug by the track of driving cam.Install and use also very simple and convenient, identical with installing and using of other kinds valve.

Timing closing valve of the present utility model is compared with existing technology, and has reasonable in design, structure Simply, be easy to processing, the characteristics such as volume is little, easy to use, can be used for various fluid-transporting tubings The timing of the upper convection cell conveying of limiting the quantity of. Thereby, have good value for applications.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.
