In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a many bores are suitable for type rising-stem plate valve, includes the valve body, the annular groove has all been opened at both ends about the valve body, threaded connection has the go-between on the annular groove, the go-between with be equipped with seal ring between the annular groove, the go-between left end rigid coupling has the connecting pipe.

Furthermore, an inner thread is arranged on one circle of the annular groove.

Furthermore, the right side of the inner wall of the connecting ring is provided with a thread groove with an annular structure, and the thread groove is in threaded connection with the annular groove.

Further, the sealing washer is sleeved on the annular groove.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is:

the utility model discloses can twist the connecting pipe of different bores on rising stem plate valve's the mouth of pipe through the go-between, make rising stem plate valve can connect on the petroleum pipeline of different bores like this, use in a flexible way, the suitability is better, the producer only needs the main part of production rising stem plate valve simultaneously, then produce different bore connecting pipe can, reduced manufacturing cost.

Detailed Description

For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.

According to the utility model discloses an embodiment provides a many bores are suitable for type rising stem plate valve.

The first embodiment is as follows:

as shown in fig. 1-2, the multi-caliber applicable rising stem flat gate valve comprises a valve body 1, annular grooves 2 are formed in the left end and the right end of the valve body 1, a connecting ring 3 is connected to the annular grooves 2 in a threaded manner, a sealing washer 4 is arranged between the connecting ring 3 and the annular grooves 2, and a connecting pipe 5 is fixedly connected to the left end of the connecting ring 3;

example two:

an internal thread is arranged on one circle of the annular groove 2, a thread groove 6 with an annular structure is arranged on the right side of the inner wall of the connecting ring 3, and the thread groove 6 is in threaded connection with the annular groove 2, so that during production, the connecting ring 3 and the connecting pipe 5 are welded together, then the sealing washer 4 is sleeved on the annular groove 2, and finally the upper thread groove 6 in the connecting ring 3 is screwed on the annular groove 2;

as shown in fig. 3-4, a manufacturer produces connecting pipes 5 with different calibers, then welds connecting rings 3 on the connecting pipes 5 with different calibers, and finally installs the connecting pipes 5 with different calibers on the rising stem flat gate valve through the connecting rings 3, so that the rising stem flat gate valve can be connected with petroleum pipelines with different calibers;

the utility model discloses a theory of operation:

when the caliber of the petroleum pipeline is increased, welding a connecting ring 3 on a connecting pipe 5 with a large caliber, sleeving a sealing washer 4 on the annular groove 2, screwing an upper thread groove 6 in the connecting ring 3 on the annular groove 2, and connecting the connecting pipe 5 with the large caliber with the petroleum pipeline with the large caliber;
