Abstract
Provided is a sleeve adjusting valve with an energy storage seal ring. The problem that a sealing device is not arranged between a valve core and a sleeve of an existing sleeve adjusting valve, and accordingly leakage occurs at the upper sealing position after a medium passes through balance holes of the sleeve and the valve core is mainly solved. The sleeve adjusting valve is characterized in that a cross section of the valve core (3) is U-shaped, the energy storage seal ring (6) is arranged between an upper sleeve (4) and a lower sleeve (5), and the valve core (3) is provided with the first position extruding the energy storage seal ring (6) and the second position separated from the energy storage seal ring (6). Due to the fact that the energy storage seal ring is arranged between the upper sleeve and the lower sleeve, the sealing performance of the valve can be greatly improved. In addition, a compensation spring is built in the energy storage seal ring, the service life is long, and the stability of the valve for long-time working is ensured.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of sleeve adjusting valve with accumulation of energy seal ring.
Background technique
Valve is the controlling component in fluid delivery system, has water conservancy diversion, dams, adjusting, throttling, prevents the functions such as refluence, shunting or overflow pressure relief.Existing sleeve adjusting valve, sleeve part adopts two-piece unit structure more, and the sealing of lower sleeve is generally metal sealing, and seal arrangement is not set between upper bush and lower sleeve, therefore cause after medium passes through the equalizing orifice of sleeve spool valve, in upper sealing place, occurring leaking.The leakage class of this valve is reduced greatly, and impact is on-the-spot to be used.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of sleeve adjusting valve with accumulation of energy seal ring, mainly solved existing sleeve adjusting valve seal arrangement has not been set between spool and sleeve, cause after medium passes through the equalizing orifice of sleeve spool valve, in upper sealing place, occurring the problem of leaking.
The technological scheme that the utility model adopts is: a kind of sleeve adjusting valve with accumulation of energy seal ring, comprise valve body, valve rod, on described valve rod, be connected with spool, in described valve body, be provided with competing upper bush, lower sleeve, described spool cross section is U-shaped, between described upper bush, lower sleeve, be provided with accumulation of energy seal ring, described spool has the primary importance and the second place separated with accumulation of energy seal ring of extruding accumulation of energy seal ring.
Described lower sleeve is provided with restriction, and described restriction size is less than valve body inner flow passage size.
On described upper bush, be extended with the first projection, be extended with the second projection on described lower sleeve, the first described projection and the second projection complement each other to form the groove with accumulation of energy seal ring adaptation.Described spool is provided with equalizing orifice.
Between described lower sleeve and valve body, be provided with gasket seal.
Described accumulation of energy seal ring includes ring body, and described ring body is enclosed with counterbalance spring, and described ring body consists of teflon.
The beneficial effects of the utility model are: owing to being provided with accumulation of energy seal ring between upper bush and lower sleeve, the sealability of valve is improved greatly, and this accumulation of energy seal ring is built-in with counterbalance spring, long service life, has guaranteed the stability of valve long-term work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at Figure 1A place.
1-valve body in figure, 2-valve rod, 3-spool, 31-equalizing orifice, 4-upper bush, 41-the first projection, 5-lower sleeve, 51-restriction, 52-the second projection, 6-accumulation of energy seal ring, 61-ring body, 62-counterbalance spring, 7-groove, 8-gasket seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 with Figure 2, a kind of sleeve adjusting valve with accumulation of energy seal ring, comprise valve body 1, valve rod 2, on described valve rod 2, be connected with spool 3, in described valve body 1, be provided with competing upper bush 4, lower sleeve 5, described spool 3 cross sections are to be provided with accumulation of energy seal ring 6 between U-shaped, described upper bush 4, lower sleeve 5, and described spool 3 has the primary importance and the second place separated with accumulation of energy seal ring 6 of extruding accumulation of energy seal ring 6.
Described lower sleeve 5 is provided with restriction 51, and described restriction 51 sizes are less than valve body 1 inner flow passage size.Open and close flexibly, valve responds is fast.
On described upper bush 4, be extended with the first projection 41, be extended with the second projection 52 on described lower sleeve 5, the first described projection 41 and the second projection 52 complement each other to form the groove 7 with accumulation of energy seal ring 6 adaptations.Compact structure, good airproof performance.Described spool 3 is provided with equalizing orifice 31.Balance valve core 3 pressure at both sides, improve spool 3 sensitivity, and valve responds is fast.
Between described lower sleeve 5 and valve body 1, be provided with gasket seal 8.Improve mechanism's sealing.
Described accumulation of energy seal ring 6 includes ring body 61, and described ring body 61 is enclosed with counterbalance spring 62, and described ring body 61 consists of teflon.After ring body 61 wearing and tearing or elastic force decline, counterbalance spring 62 starts that supporting comes realizes sealing compensation, has improved the working life of mechanism.
The concrete use of the utility model is as follows: during work, spool 3, under valve rod 2 drives, pushes counterbalance spring 62, enters the medium of equalizing orifice 31, cannot be by the sealing surface between spool 3 and upper bush 4; The coated counterbalance spring 62 of ring body 61, counterbalance spring 62 is interference fit with groove 7.After seal ring work a period of time, due to reasons such as wearing and tearing, extruding, distortion, size can change to some extent, and now counterbalance spring 62 starts to support to come and realizes sealing compensation, the sealing of compensation can guarantee that Sealing works on, and realizes the function of permanent stabilized seal.
The beneficial effect of model utility is: owing to being provided with accumulation of energy seal ring between upper bush and lower sleeve, the sealability of valve is improved greatly, and this accumulation of energy seal ring is built-in with counterbalance spring, long service life, has guaranteed the stability of valve long-term work.
