Abstract
The utility model relates to a valve, this valve include hand wheel, valve shaft and valve body, hand wheel and valve shaft fixed connection, and valve shaft and valve body screw thread swing joint are equipped with the sealed pad of valve shaft between valve shaft and the valve body, and the lower extreme of valve shaft is equipped with the sealing washer rather than fixed connection, and the valve shaft bottom coincide for the cockscomb structure with the end cover and is connected. The utility model discloses simple structure is exquisite, seals pad, sealing washer and sealed piece through the valve shaft and reaches multiple layer sealing, makes valve have excellent sealed effect, the utility model discloses valve shaft and end cover cusp meet, and better prevent valve shaft and end cover junction form the space and the gas leakage that leads to leaking, the utility model discloses easily production processing, and later stage simple installation, labour saving and time saving.
Description
Technical field
The present invention relates to a kind of valve.
Background technique
Valve is the controlling component in fluid delivery system, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.
Valve is of a great variety, specifically can be divided into block class, vacuum types and some there is the valve of specific use.There is many deficiencies in existing valve, due to complex structural designs, causes wasting time and energy when manufacturing, and also installs to the later stage simultaneously and bring very big inconvenience; In addition, still there is the problem of poor sealing in existing a lot of valve, in use causes very large puzzlement to client.
In order to solve the problem, the application makes improvements existing valve, designs the simple exquisiteness of a kind of structure and the valve of sealing excellence.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of valve, this valve mechanism simple seal is good, is convenient to manufacturing.
Technological scheme of the present invention:
A kind of valve, comprise handwheel, valve shaft and valve body, handwheel is fixedly connected with valve shaft, valve shaft is flexibly connected with valve body screw thread, be provided with valve shaft sealing gasket between valve shaft and valve body, the lower end of valve shaft is provided with the seal ring be fixedly connected with it, and being that flexuose is identical with end cap bottom valve shaft is connected.
Sealing block is provided with between described end cap and valve body.
Described end cap is convex architecture.
Beneficial effect: the first, structure of the present invention is simply exquisite, reaches multi-layer sealed by valve shaft sealing gasket, seal ring and sealing block, makes valve have excellent sealing effect; The second, valve shaft of the present invention and end cap dentation connect, and better prevent valve shaft and formation space, end cap joint and cause leaking gas leakage; 3rd, the present invention is easy to production and processing, and later stage simple installation, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1-handwheel, 2-valve shaft, 3-valve shaft sealing gasket, 4-valve body, 5-seal ring, 6-sealing block, 7-end cap.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, a kind of valve, comprise handwheel 1, valve shaft 2 and valve body 4, handwheel 1 is fixedly connected with valve shaft 2, valve shaft 2 is flexibly connected with valve body 4 screw thread, be provided with valve shaft sealing gasket 3 between valve shaft 2 and valve body 4, the lower end of valve shaft 2 is provided with the seal ring 5 be fixedly connected with it, and coincideing for flexuose with end cap 7 bottom valve shaft 2 is connected.
In order to make this valve have better sealing, sealing block 6 can be provided with between end cap 7 and valve body 4.
The end cap 7 of this valve is convex architecture, on the top of convex architecture, there is groove, this groove with valve shaft bottom groove match, better can prevent valve shaft and formation space, end cap joint and cause leaking gas leakage, thus further improve the sealing of this valve.
Above-described embodiment is only the explanation to product of the present invention; not any pro forma restriction is made to the present invention; do not departing within technological scheme scope of the present invention, any equivalent utilizing the technology contents of above-mentioned announcement to make simple transformation, all belongs to protection scope of the present invention.
