Abstract
The invention discloses a quick-acting valve, comprising a valve body. A valve element and a valve stem are disposed inside the valve body, the valve element is fixedly mounted on the lower portion of the valve stem, a guide bushing is fixedly mounted on the inner wall of the valve body, the valve stem passes through the guide bushing, the valve stem and the guide bushing are hermetically connected, the top of the valve body is provided with an opening and closing device that comprises a shell, a cam and a rocker, the shell is of hollow structure, the shell is fixedly mounted at the upper end of the valve body, one end of the cam is movably mounted on the inner wall of the shell through a rotary shaft, the other end of the cam is fixedly connected with the rocker, and a pull spring is disposed between the valve element and the guide bushing. The rotational motion of the rotary cam is converted into linear motion of the valve stem by using the cam mechanism, a user feels easier to open or close the valve, and additionally, the elasticity of the pull spring can overcome the weight of the valve stem and valve element to enable quick opening during opening of the valve.
Description
technical field:
The invention belongs to valve technology field, especially relate to a kind of fast opening/closing valve.
background technique:
The effect of valve is generally used for cut-off and adjustment flow, occurs breaking, or when the medium in pipeline occurs to leak, often need valve to carry out quick closedown at pipeline.When valve conducting, it is often needed again to open fast.Say from technological layer, electric valve also can fast opening and closing, but there is two problems, one is that it involves great expense, even if two being for guaranteeing people's life safety, disregarding cost and installing electric valve, also also exist when having an accident, often along with power failure, though electric valve can change into manually, it is still very slow that it opens and closes speed.
summary of the invention:
Technical problem to be solved by this invention is: provide a kind of valve utilizing the elasticity of cam mechanism and extension spring to open as soon as possible or to close.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of fast opening/closing valve, comprise valve body, described valve inner is provided with spool and valve rod, described spool is fixedly mounted on the bottom of valve rod, the inwall of described valve body is installed with guide sleeve, described valve rod is through guide sleeve, and adopt between valve rod and guide sleeve and be tightly connected, described body top is provided with opening and closing device, described opening and closing device is by housing, cam and rocking bar composition, described housing is hollow structure, and the upper end being fixedly mounted on valve body of housing, one end of described cam is movably arranged on the inwall of housing by rotating shaft, the other end of described cam is fixedly connected with rocking bar, extension spring is provided with between described spool and guide sleeve.
As preferably, the track led when described housing is provided with for rotating cam, described cam is fixedly installed the bearing pin stretching into track.
As preferably, described valve stem top is provided with the circular groove matched with cam.
As preferably, the quantity of described extension spring is provided with four.
Compared with prior art, usefulness of the present invention is: the present invention adopts cam mechanism to be the straight line motion of valve rod by the convert rotational motion of rotating cam, user is more laborsaving when unlatching or throttle down, in addition, when valve opening, the elastic force of extension spring can overcome the gravity of valve rod and spool, and then plays the effect of opening fast.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is opening state schematic diagram of the present invention.
Fig. 2 is closed condition schematic diagram of the present invention.
In figure: 1, valve body; 11, track; 2, spool; 3, valve rod; 41, housing; 42, cam; 43, rocking bar; 5, guide sleeve; 6, extension spring.
embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of fast opening/closing valve as depicted in figs. 1 and 2, comprise valve body 1, described valve body 1 inside is provided with spool 2 and valve rod 3, described spool 2 is fixedly mounted on the bottom of valve rod 3, the inwall of described valve body 1 is installed with guide sleeve 5, described valve rod 3 is through guide sleeve 5, and adopt between valve rod 3 and guide sleeve 5 and be tightly connected, described valve body 1 top is provided with opening and closing device, described opening and closing device is by housing 41, cam 42 and rocking bar 43 form, described housing 41 is hollow structure, and the upper end being fixedly mounted on valve body 1 of housing 41, one end of described cam 42 is movably arranged on by rotating shaft on the inwall of housing 41, the other end of described cam 42 is fixedly connected with rocking bar 43, extension spring 6 is provided with between described spool 2 and guide sleeve 5.
The track 11 led when described housing 1 is provided with for rotating cam 42, described cam 42 is fixedly installed the bearing pin stretching into track 11, adopt this structure, cam 42 runs on fixing track 11, while raising accurately operation degree, track 11 also can be played a supporting role to cam 42, reduces to cause damage to cam 42 around central rotating shaft in Long-Time Service process.
Touch valve rod 3 for the ease of cam 42 to move downward, described valve rod 3 top is provided with the circular groove matched with cam 42, and described circular groove is the groove of arc point at top.
The quantity of described extension spring 6 is provided with four, adopts this structure, can realize the uniform stressed of extension spring 6 pairs of spools 2, avoids spool 2 to occur skew.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
