Abstract
The utility model provides a manual parallel gate valve, which comprises a valve seat and a valve body. The valve seat and the valve body are sealed by a sealing ring, a wave spring is arranged at one end of the valve seat connected with the valve body, at least one step is additionally arranged at the connecting joint of the valve seat and the valve body, an O-shaped sealing ring is transversely arranged at the step, and the wave spring is arranged longitudinally at the step. During usage, impurities passing through a clearance between the valve seat and the valve body are blocked externally under actions of the sealing ring and the step, and then the impurities can not enter the wave spring during long-term usage of the gate valve, thereby achieving fine air tightness of the valve cavity and long service life of the parallel gate valve.
Description
Technical field
The utility model relates to a kind of manual parallel gate valve, particularly relate to a kind of manual parallel gate valve, be mainly used in oil and gas industry, purposes is very extensive, is one of requisite standard piece in the multiple petroleum machineries such as wellhead for production, throttling and kill manifold.
Background technique
Present manual parallel gate valve series product, simple in structure, easy to operate, its quality and performance are in use more stable always, but also exist shortcoming, especially after using for a long time, impurity can enter the position of wavy spring, has reduced the elasticity of wavy spring, cause the Gate-valve sealing performance to reduce, influence its working life.
As Fig. 1 and Fig. 2, Fig. 1 is existing manual parallel gate valve structure schematic representation, Fig. 2 is the partial enlarged drawing of Fig. 1, valve seat and valve body joint level are excessive, in long-term use, impurity sticks into wavy spring 4 easily and causes wavy spring nonelastic, makes can not guarantee sealing in the valve pocket and influence whole service life.
The model utility content
The utility model provides a kind of manual parallel gate valve, good seal in the valve pocket, whole service life height.
In order to achieve the above object, the utility model provides a kind of manual parallel gate valve, comprises valve seat and valve body, and valve seat and valve body are airtight by seal ring, wavy spring is arranged on the end that valve seat is connected with valve body, increases at least one step at described valve seat and valve body joint.
Further, be horizontally arranged with seal ring at described step.
In use, impurity is stopped in the outside during by valve seat and valve body gap under the effect of O RunddichtringO and step, so just can prevent that gate valve from having impurity to enter wavy spring in using for a long time, thus the valve pocket good leak tightness, parallel gate valve long service life.
Description of drawings
Fig. 1 is existing manual parallel gate valve structure figure;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the manual parallel gate valve structure figure of the utility model embodiment;
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Please refer to Fig. 3 and Fig. 4, the manual parallel gate valve of present embodiment increases step 6 at the valve seat 1 of existing manual parallel gate valve with valve body 2 joints, in order to reach better sealing effect, the step 6 that increases can be a plurality of steps, specifically decide on use condition, wavy spring 4 is arranged on the vertical of step, as another embodiment of the present utility model, laterally seal ring 5 is set the place at step, valve seat 1 and valve body 2 are sealed, described seal ring 5 can be the O RunddichtringO, in use, impurity is stopped in the outside during by valve seat 1 and valve body 2 gaps under the effect of seal ring 5 and step 6, so just can prevent that gate valve from having impurity to enter wavy spring in using for a long time.
Though the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Have in the technical field under the utility model and know the knowledgeable usually, in not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is as the criterion when looking claims person of defining.
