Abstract
The utility model discloses an elastic seat sealed gate valve which comprises a valve body, a valve cover, a valve rod, a hand wheel and a valve plug, wherein the valve cover is fixedly connected with the valve body through a bolt, the valve rod penetrates the valve cover, the outer end of the valve rod is connected with the hand wheel, and the inner end of the valve rod is connected with the valve plug. A sealing seat is arranged between the valve plug and the valve body and is matched with a groove part of the valve plug. Therefore, the elastic seat sealed gate valve is novel in structure and convenient to install, has the advantages of being reasonable in structure, good in sealing effect, easy to operate and the like, and can prolong product service life.
Description
Technical field
The utility model relates to valve technology field, and particularly spring support is sealed gate valve up for safekeeping.
Background technique
In the existing gate valve, it is tabular that its spool normally is, i.e. usual said flashboard.Sharp
Come the switching of control valve with the lifting of flashboard.When gate valve is closed, seal by flashboard.
As " soft sealing gate valve " that Chinese patent 982294522 provides, it comprise valve body, sealing seat,
Flashboard and flashboard operating mechanism, the first half of sealing seat are semicircle, and Lower Half is the V font,
Flashboard also has corresponding structure.Utilize cooperatively interacting of flashboard and sealing seat, gate valve is closed
Close.Though this patented technology is to make the sealing raising of gate valve, anti-corruption by the soft material layer
The enhancing of erosion property.But identical with common flashboard type gate valve, exist many deficiencys,
Be that mainly sealing surface is little, and wearing and tearing easily.Particularly work as some impurity and be sandwiched in the sealing surface place
The time, cause poorly sealedly easily, leakage phenomenon appears, influence the working life of gate valve.
On the other hand, common gate valve is required great effort during operation because volume is bigger, directly shadow
Ring the normal use of gate valve.
The model utility content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide spring support to seal gate valve up for safekeeping, and this elasticity is sealed the gate valve structure novelty up for safekeeping, makes it have characteristics such as rational in infrastructure, good seal performance, operation be light.
In order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: spring support is sealed gate valve up for safekeeping, comprise valve body, valve gap, valve rod, handwheel and spool composition, described valve gap and valve body are bolted to connection, described valve rod passes valve gap, and the valve rod outer end is connected with handwheel, and valve rod is inner to be connected with spool, be provided with sealing seat between described spool and the valve body, sealing seat matches with groove part at spool.
The utility model advantage compared with prior art is: owing to be provided with above structure, this elasticity is sealed the gate valve structure novelty up for safekeeping, and is easy for installation, makes it have characteristics such as rational in infrastructure, good sealing effect, operation be light, can prolong product working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
With reference to shown in Figure 1, spring support is sealed gate valve up for safekeeping, comprise valve body 1, valve gap 2, valve rod 3, handwheel 4 and spool 5 compositions, described valve gap 2 is bolted to connection with valve body 1, described valve rod 3 passes valve gap 2, valve rod 3 outer ends are connected with handwheel 4, valve rod 3 the inners are connected with spool 5, be provided with sealing seat 6 between described spool 5 and the valve body 1, sealing seat 6 matches with 7 ones of grooves at spool, and this elasticity is sealed the gate valve structure novelty up for safekeeping, and is easy for installation, make it have characteristics such as rational in infrastructure, good sealing effect, operation be light, can prolong product working life.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
