Abstract
The utility model relates to a novel connecting structure for a valve body and a valve seat. The novel connecting structure is characterized in that the top of the valve seat extends outward along the horizontal direction so as to form a step; the bottom of the valve seat is inserted into the valve body and is connected and fixed with the valve body by screw threads; and the step tightly compresses the top surface of the valve body. According to the novel connecting structure, the valve body and the valve seat are fixed and connected in a threaded connection manner, so that the novel connecting structure for the valve body and the valve seat is simple and reasonable in structure, is easy to install and can reduce the processing cost and the maintenance difficulty; and the valve seat can be detached for being changed when the sealing surface of the valve seat is damaged, so that a valve can be ensured to work effectively for a long term, and the service life is prolonged.
Description
Technical field
The utility model relates to valve field, is specifically related to the linkage structure of a kind of novel valve body and valve seat.
Background technique
Traditional valve body and general employing of being connected of the valve seat form in the valve body that valve seat is welded direct to as shown in Figure 1; In the using process of valve; Sealing surface is if any damaging or when needing repairing, disassembling whole valve products, and efficient is low and influence is normal produces.
Summary of the invention
The technical problem that the utility model will solve provides the linkage structure of a kind of novel valve body and valve seat, and this is simple and reasonable, be easy to install, can cut down finished cost and maintenance difficulty, guarantees valve operation efficiently for a long time.
The technological scheme that the utility model addresses the above problem is:
The linkage structure of a kind of novel valve body and valve seat; It is characterized in that: the outside horizontal-extending in the top of said valve seat forms step; Insert in the said valve body bottom of said valve seat, and the bottom of said valve seat is threaded fixing with said valve body, and said step compresses the end face of said valve body.
Further,
Threads engaged on screw thread on the outer wall of the bottom of said valve seat and the said valve interior wall makes said valve seat be threaded fixing with said valve body.
Be provided with pad between the end face of said step and said valve body.
The utility model is fixedly connected valve body with the mode that is threaded with valve seat; Simple and reasonable for structure, be easy to install, can cut down finished cost and maintenance difficulty; When sealing surface of seat has damage; Only need the dismounting valve seat and change valve seat to get final product, therefore can guarantee valve operation efficiently for a long time, increase the service life.
Description of drawings
Fig. 1 is the schematic representation of linkage structure of valve body and the valve seat of existing technology.
Fig. 2 is the schematic representation of linkage structure of valve body and the valve seat of the utility model.
Description of reference numerals
1, valve seat 2, valve body 3, step 4, pad 5, soldering point
Specific embodiments
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 2; A kind of novel valve body of the utility model and the linkage structure of valve seat, the outside horizontal-extending in the top of valve seat 1 forms step 3, and insert in the valve body 2 bottom of valve seat 1; The bottom of valve seat 1 is threaded fixing with valve body 2, step 3 compresses the end face of valve body 2.
In this example, screw thread on the outer wall of the bottom of valve seat and the threads engaged on the valve interior wall, it is fixing that valve seat is threaded with valve body.The utility model is fixedly connected valve body with the mode that is threaded with valve seat; Simple and reasonable for structure, be easy to install, can cut down finished cost and maintenance difficulty; When sealing surface of seat has damage; Only need the dismounting valve seat and change valve seat to get final product, therefore can guarantee valve operation efficiently for a long time, increase the service life.
In this example, also be provided with pad 4 between the end face of step 3 and valve body 2,, prevent to reveal further with strong sealing effect.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technological scheme to any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. the linkage structure of novel valve body and valve seat; It is characterized in that: the outside horizontal-extending in the top of said valve seat forms step; Insert in the said valve body bottom of said valve seat, and the bottom of said valve seat is threaded fixing with said valve body, and said step compresses the end face of said valve body.
2. the linkage structure of a kind of novel valve body according to claim 1 and valve seat is characterized in that: the threads engaged on screw thread on the outer wall of the bottom of said valve seat and the said valve interior wall makes said valve seat be threaded fixing with said valve body.
