Description

Timed valve

One, technical field

The utility model relates to valve, particularly a kind of rock gas, coal gas, liquefied petroleum gas pipeline Timed valve.

Two, background technique

Our employed pipeline valve is a kind of traditional flashboard screw thread rotation compression type structure substantially at present, to being used for the resident with the feed channel valve, there are a lot of hidden danger, it is more that the poisoning explosive accident takes place, especially the oil field has an accident morely winter, causes the people's full property of life and national economy loss serious.

Three, summary of the invention

The technical problems to be solved in the utility model provides and a kind ofly can overcome and avoid the shortcoming and defect of above-mentioned prior art and have the handling characteristics of existing common valve, have again can be regularly Timed valve.Timer and valve combine as a whole, and install, operation is very easy, have solved because of forgetting the explosion caused and long-time burning of pass gas oxygen depletion and the difficult problem of suffocating well.The technical solution of the utility model solves in the following manner.

A kind of home-use Timed valve, by valve seat, valve body, pressure cap, spool, valve thick stick and handwheel are formed, it is characterized in that valve body is rounded, be threaded between forming by valve body up and down, establishing male thread on the upper valve body cooperates with the box thread of pressure cap, divide into box thread with on divide into the last male thread that the following valve of male thread stops and cooperate, the following male thread of following valve body cooperates with the box thread of valve seat, the upper valve body middle part is provided with the fitting seat of the timer of band box thread, the timer of selling on the market is housed on it, the middle and lower part of valve body is provided with a round boss separately up and down, the valve thick stick is made up of valve thick stick up and down, be connected by the ball bowl of last valve thick stick band and the ball of following valve band between the valve thick stick up and down, be provided with T shape screw thread at the middle part of last valve thick stick, be subjected to the upward rotation of valve thick stick of stop pin control of timer, be provided with elastic force in the lower valve body cavity and be higher than the spring of bleed pressure more than three times, press down valve thick stick up and down all the time, when the timing usefulness gas time finishes, the locking lock of timer rebounds, and closes gas check valve automatically by the spring in the following valve body.

Be provided with copper sheathing, copper sheathing and pressure cap screw-thread fit between pressure cap and the last valve thick stick, the copper sheathing internal diameter is provided with a keyway, and last valve thick stick periphery is provided with a key, both are slidingly matched.

The round boss internal diameter of upper valve body is square less than the external diameter of T shape screw thread set on the last valve thick stick, its center hole of round boss of following valve body, boss has a spill rubber seal seat, the upper end is pushed by the gland with following valve body screw-thread fit, and the lower end is compressed in down the set nut screwing clamping extruding of set circular bulge loop in valve thick stick bottom and valve thick stick lower end.

The profile of following valve thick stick middle and upper part is established rectangular, cooperates with the round boss center square hole of following valve body, allows down the valve thick stick can only make straight line motion up and down.

The utility model has been compared following advantage 1, not can be used as common valve usefulness when not needing regularly usefulness gas at ordinary times with background skill skill, only cooperate the left rotation and right rotation handwheel by key on the last valve thick stick and the keyway on the copper sheathing, makes up and down the valve thick stick switching valve that moves up and down.When 2, needing at ordinary times regularly to use gas, the rotary timer handle makes stop pin be inserted in T shape screw thread the inside of valve thick stick, and this moment, T shape screw thread was that fulcrum rotates to rise and opens valve with the stop pin.Drive the upwards rotation together of valve thick stick up and down of copper sheathing, T shape screw thread with rotating handwheel, open valve, when locking usefulness gas time up, the spring that stop pin is timed device the inside rebounds, T shape screw thread is out of control, spring in following valve body 7 chambeies presses down valve thick stick up and down, and the key on the last valve thick stick glides along the keyway on the copper sheathing, automatic-closing valve.Solved well because of forgetting the pass air valve, long-term burning causes anoxic, the problem that makes people's anoxia asphyxia or fire go out and set off an explosion.

Five, embodiment

For further illustrating the technical solution of the utility model, be described in detail below in conjunction with Figure of description:

The utility model is made up of valve seat 9 upper valve bodies 4, time valve body 7, pressure cap 2 spools, last valve thick stick 3, following valve thick stick 5 and handwheel 1.Valve body is rounded, be threaded between the valve body up and down, establishing male thread on the upper valve body cooperates with the box thread of pressure cap, divide into box thread with on divide into the following valve body of male thread last male thread cooperate, the following male thread of following valve body cooperates with the box thread of valve seat, the upper valve body middle part is provided with the timer fitting seat of band box thread, on its seat timer 15 is housed, the middle and lower part of upper valve body is provided with a round boss separately, the valve thick stick is by last valve thick stick 3, following valve thick stick 5 is formed, be connected by the ball bowl 8 of last valve thick stick band and the ball of following valve thick stick between the valve thick stick up and down, be provided with T shape screw thread at the middle part of last valve thick stick, be subjected to the upward rotation of valve thick stick of stop pin 16 controls of timer 15, be provided with spring force in following valve body 7 chambeies and be higher than the spring 14 of bleed pressure more than three times, all the time press down valve thick stick up and down, when the timing usefulness gas time finished, the locking of timer lock 16 rebounded by spring, and T shape screw thread is out of control, by valve thick stick timeing closing valve about valve body 7 interior springs press down down, guarantee to use gas safety.The box thread of pressure cap 2 cooperates with the male thread of copper sheathing 12, and a left side or right rotation handwheel 1 make the switch valve that moves up and down.Last valve thick stick 3 only moves up and down under the control of valve thick stick and round boss center square hole in descending valve body 7 down with handwheel 1 rotation, can not rotate, and be in order to protect rubber seal seat 10 spools and valve seat not to be worn.

When needing at ordinary times regularly to use gas, the rotary timer handle, stop pin 16 is inserted in the T shape screw thread of valve thick stick 3, this moment, T shape screw thread was the fulcrum rotation with stop pin 16, could work to open valve, timer 15 just can work, rotate handwheel 1 and drive copper sheathing 12, T shape screw thread, valve is shouldered upwards motion together and is promptly opened valve up and down, and when institute used the gas time up surely, stop pin was rebounded by 16 springs that are timed device 15 the insides, T shape screw thread is vowed control, spring in lower valve body cavity presses down up and down valve thick stick, forces key 11 on the valve thick stick 3 and valve thick stick along copper sheathing 12 downslide automatic-closing valves.The utility model has solved well forgets the pass air valve, the problem that long-term burning causes anoxia asphyxia or fire to go out and set off an explosion.
