Abstract
nullThe utility model relates to a kind of Novel soft sealed gate valve，Including valve body、Valve gap、Gland、Flashboard、Valve rod and unlatching handwheel，Described valve body has water inlet and the delivery port of through medium fluid，Described valve gap is located above valve body，Described gland is dismantled and assembled to be located above valve gap，Described flashboard can being located between water inlet and delivery port of oscilaltion，One end of described valve rod passes through gland and valve gap is threadeded with valve stem nut，Described valve stem nut is located in flashboard upper end，Described unlatching handwheel is located on the free end of valve rod，This gland inwall is provided with a circle seal groove，It is provided with a V-shaped seal ring that Open Side Down in this seal groove，Under the pressure of liquid，V-shaped seal ring both sides are softened，Fit with seal groove inwall and valve rod outer wall respectively，I.e. seal，Valve rod need not be slotted，Assembling and process time can be saved，Improve operating efficiency，And extend valve service life，Improve valve seal performance.
Description
Technical field
The utility model relates to a kind of fluid control valve, a kind of Novel soft sealed gate valve.
Background technology
It is to be sealed by O-ring between the valve rod of existing soft sealing gate valve and gland, one to three O-ring groove on valve rod, O-ring groove O-ring being enclosed within valve rod, O-ring just must can play sealing effectiveness with gland reasonable coordination afterwards, this is not only installing certain difficulty, and under any state, when the switch of gate valve closes, friction can be produced between O-ring and valve rod or gland, abrasion to O-ring is very fast, sealing property cannot ensure, easily produces drainage particularly in a low voltage state.The service life shortening gate valve reduces.
Utility model content
In place of solving the deficiencies in the prior art, the utility model provides a kind of Novel soft sealed gate valve.
A kind of Novel soft sealed gate valve, including valve body, valve gap, gland, flashboard, valve rod and unlatching handwheel, described valve body has water inlet and the delivery port of through medium fluid, described valve gap is located above valve body, described gland is dismantled and assembled to be located above valve gap, described flashboard can being located between water inlet and delivery port of oscilaltion, one end of described valve rod passes through gland and valve gap is threadeded with valve stem nut, described valve stem nut is located in flashboard upper end, described unlatching handwheel is located on the free end of valve rod, described gland inwall is provided with a circle seal groove, it is provided with a V-shaped seal ring that Open Side Down in described seal groove.
The beneficial effects of the utility model:
V-shaped seal ring in the utility model embeds in the seal groove of gland inwall, and Open Side Down, in the absence of stress, V-shaped seal ring is under conventional sense, and rotation hand wheel opens or closes gate valve, and V-shaped seal ring is not rotated by valve rod, frictional force between V-shaped seal ring and valve rod or gland is zero, so at gate valve of the present utility model in the absence of stress, V-shaped seal ring without abrasion, can be improved service life greatly by switch gate valve.
In the case of having hydraulic pressure, under the effect of hydraulic pressure, the both sides of V-shaped seal ring strut to both sides, fit with the inwall of valve rod and seal groove respectively, i.e. serve the effect of sealing, when low pressure or high pressure, sealing property all has and significantly promotes, and extends valve service life.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing in A portion in Fig. 1.
Detailed description of the invention
As shown in Figure 1 to Figure 2, a kind of Novel soft sealed gate valve, including valve body 1, valve gap 2, gland 3, flashboard 4, valve rod 5 and unlatching handwheel 6, described valve body 1 has water inlet and the delivery port of through medium fluid, described valve gap 2 is located above valve body 1, described gland 3 is dismantled and assembled to be located above valve gap 2, described flashboard 4 can being located between water inlet and delivery port of oscilaltion, one end of described valve rod 5 passes through gland 3 and valve gap 2 is threadeded with valve stem nut 41, described valve stem nut 41 is located in flashboard 4 upper end, described unlatching handwheel 6 is located on the free end of valve rod 5, described gland 3 inwall is provided with a circle seal groove 31, it is provided with a V-shaped seal ring 7 that Open Side Down in described seal groove 31.
It is last it is noted that above example is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model, it all should be covered in the middle of right of the present utility model.
