Abstract
The utility model discloses a fully-plastic-blowing soft sealing sluice valve which comprises a valve body, a flashboard which is provided in the cavity of the valve body and a valve stem which controls the motion of the valve plate to close and open; wherein the cavity of the valve body has a wedge structure, a plastic layer wraps the outside surface of the flashboard, and a non-toxic epoxy powder coating is sprayed onto the surface of the cavity of the valve body. The utility model has the advantages that the outside surface of the flashboard is wrapped by a plastic layer and the surface of the cavity of the valve body is coated with a non-toxic epoxy powder coating which adheres hard to both the inside surface and the outside surface of the castings after being treated by thermo-fixation so as to block the contact between the cavity of the valve body or the flashboard with the medium to prevent secondary pollution in the main-water. Because the contact between the valve body and the inferior sealing face of the flashboard is a plane sealing contact, the problem of sedimentation of impurity. The sedimentation of impurity is eliminated and the choking of flow is reduced. Because one member of the sealing pair is made from non-toxic rubber and the other member is a very slippery epoxy powder coating layer, the frictional force is small, the service life is long and the force moment for start and shut is small.
Description
Technical field
The utility model relates to the gate valve that is used on the urban pipe network circulating water pipeline, especially relates to full plastic-blasting soft sealing gate valve.
Background technique
Existing gate valve owing to adopt shape metallic leak-proof structure in use has the following disadvantages more: 1, valve body, flashboard, sealing pair need process, directly knocking causes secondary pollution to tap water in medium.2, existing gate valve comprises stainless steel and blass stop valve, and a groove is all arranged at their bottom, is very easy to the impurity in the deposition medium, becomes the breeding ground of pollution medium.3, general gate valve uses asbestos packing or graphite packing, and is unhygienic, can pollution medium.4, unlatching moment is big.
The model utility content
The utility model purpose is to provide a kind of full plastic-blasting soft sealing gate valve at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be taked following technical proposals:
Full plastic-blasting soft sealing gate valve described in the utility model, it comprises valve body, is arranged on the flashboard in the described body cavity and handles the valve rod that this flashboard opens and closes up and down, described body cavity is the wedge-type structure; Be coated with glue-line at the flashboard outer surface; Be coated with nontoxic epoxy powder coating layer on the body cavity surface.
For stopping the impurity deposition, described valve body is that plane sealing contacts with the lower seal face of flashboard.
Advantage of the present utility model is to take to be coated with glue-line at the flashboard outer surface; Be coated with nontoxic epoxy powder coating layer on the body cavity surface, after heat cure is handled, very securely attached to the inner and outer surface of foundry goods, thereby blocked contacting of body cavity, flashboard etc. and medium, can not cause secondary pollution to tap water, therefore, applicable price expensive stainless steel valve and the copper valve of in senior house and hotel, substituting.Because valve body is that plane sealing contacts with the lower seal face of flashboard, therefore solved the impurity deposition problems, neither can reduce choked flow again by deposition medium.Because of a side of sealing pair is a nontoxic rubber, the opposing party is the sliding epoxy coating of non-ordinary light, so frictional force is very little, long service life not only, and also it is little to open and close moment, has only the metal lot seal gate valve to open and close moment 1/3-1/4, and operation is very easy.Because it is little to open and close moment, therefore can carry out Open valve with stock very easily, every deck valve door of road pipe network need not to be provided with valve well, but soft sealing gate valve is directly imbedded underground, has saved valve well, has reduced engineering cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
As shown in the figure, full plastic-blasting soft sealing gate valve described in the utility model, it comprises valve body 1, is arranged on the flashboard 2 in described valve body 1 inner chamber and handles the valve rod 3 that this flashboard 2 opens and closes up and down, the inner chamber of described valve body 1 is the wedge-type structure; Be coated with glue-line 4 at flashboard 2 outer surfaces; Be coated with nontoxic epoxy powder coating layer at valve body 1 surface of internal cavity.For stopping the impurity deposition, valve body 1 is that plane sealing contacts with the lower seal face of flashboard 2.
Claims (2)
1, a kind of full plastic-blasting soft sealing gate valve, it comprises valve body (1), is arranged on the flashboard (2) in described valve body (1) inner chamber and handles the valve rod (3) that this flashboard (2) opens and closes up and down, it is characterized in that: the inner chamber of described valve body (1) is the wedge-type structure; Be coated with glue-line (4) at flashboard (2) outer surface; Be coated with nontoxic epoxy powder coating layer at valve body (1) surface of internal cavity.
