Abstract

The utility model provides a stock valve, include: valve clack and disk seat are established to the valve body in, the lower valve rod is connected to the lower extreme of valve clack, and the valve rod is connected to the upper end of valve clack, and valve rod one end lies in the valve body, outside the other end of valve rod stretches out the valve body, the valve rod that stretches out the valve body outer is located the pillar, and pillar one end is connected on the valve body. Its installation need not to set up secret valve well again the time, but the direct mount underground or the aquatic.

Description

Long stem valve
Technical field
This utility model relates to a kind of valve, particularly relates to a kind of long stem valve.
Background technology
Needing to arrange substantial amounts of valve at present in municipal water supply and sewage disposal pipe network, to control the day-to-day operation of pipe network, and these valves typically require and are arranged in underground valve well, in order to the control of operator.But building these underground valve wells and often take up room relatively big, and need large-area construction, the bigger construction period of quantities is longer, and construction cost is higher.If valve directly to be imbedded underground, owing to the valve rod of valve belongs to movable part, it is chronically under wet environment easily corrosion, thus the situation causing valve to open and close, make valve invalidation at this, need again to change valve.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides a kind of long stem valve, without underground valve well when it is installed, can directly imbed underground.
To achieve these goals, the technical scheme that this utility model is used includes: valve body, flap and valve seat is set in valve body, the lower end of flap connects lower valve rod, the upper end of flap connects valve rod, and one end of valve rod is positioned at valve body, and the other end of valve rod stretches out outside valve body, the described valve rod stretched out outside valve body is positioned at pillar, and pillar one end is connected on valve body.
The described valve rod stretched out outside valve body connects actuator, and actuator connects the other end of pillar.
Described pillar includes: pillar body, pillar body two ends adpting flange respectively.
The outside of described valve seat is provided with valve seat gland, and valve seat is positioned between valve seat gland and valve body, is provided with spring between described valve seat and valve seat gland.
Of the present utility model by by valve stem seal in pillar, make valve rod and the steam isolation in working environment, avoid the valve invalidation that the corrosion of valve rod causes, so that valve can directly be imbedded underground or be arranged in water, be effectively increased the adaptive capacity to environment of valve.Secondly, use the valve seat floated to coordinate with flap, make valve achieve two way seal.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1. sealing gasket, 2. valve body, 3. lower valve rod, 4. valve seat gland, 5. valve seat, 6. flap, 7. valve rod, 8. spring, 9. valve seat insert, 10. pillar sealing ring, 11. bolts, 12 pillars.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As it is shown in figure 1, embodiment of the present utility model is as follows: valve body 2, valve body 2 is made up of valve body and base plate, is provided with sealing gasket 1 between base plate and valve body.Flap 6 and valve seat 5 is set in valve body 2, the lower end of flap 6 connects lower valve rod 3, the upper end of flap 6 connects valve rod 7, one end of valve rod 7 is positioned at valve body 2, the other end of valve rod 7 stretches out outside valve body 2, the described valve rod 7 stretched out outside valve body 2 is positioned at pillar 12, and one end of pillar 13 is connected on valve body 2 by bolt 11.The described valve rod 7 stretched out outside valve body 2 connects actuator, and actuator connects the other end of pillar 13.Described pillar 13 includes: pillar body, pillar body two ends adpting flange respectively, is provided with pillar sealing ring 10, also is provided with pillar sealing ring 10 between flange and actuator between flange and valve body 2.
Setting valve seat 5 in described valve body 2, the outside of valve seat 5 is provided with valve seat gland 4, and valve seat 5 is positioned between valve seat gland 4 and valve body 2, is provided with spring 8, is provided with valve seat insert 9 between valve seat 5 and valve body 2 between described valve seat 5 and valve seat gland 4.When the valve in Fig. 1 of the medium in pipeline is flowed to the right by the left side of valve body, the pretightning force provided by the spring 8 between valve seat 5 and valve seat gland 4, and the thrust of medium, promote valve seat 4 realization that is attached on flap 5 tightly to seal.When medium valve in Fig. 1 is flowed to the left by the right side of valve body, medium promotes flap 6 to be moved to the left, now valve seat 4 and valve seat gland 3 are adjacent to, spring 7 lost efficacy, valve seat gland 4 stops the retrogressing of valve seat 5, thus ensure forced seal between valve seat 5 and flap 6, it is achieved thereby that the two way seal of this utility model valve.
