Referring to fig. 1-5, the present invention provides an embodiment: a straight-through speed control valve with display scales comprises a valve body 1 and a counter 3 arranged on the valve body 1; the counter 3 comprises a bottom shell 32 and a dial 31 arranged on the bottom shell 32, wherein the dial 31 is connected with a valve core 11 through a linkage rod 6; the periphery of the linkage rod 6 is also provided with a driving part 5, and the driving part 5 is in contact with a driven part 33 arranged inside the dial 31 through the rotation of the linkage rod 6, so that the dial 31 rotates along with the linkage rod 6.

According to the technical scheme, the counter 3 is fixed on the valve seat 8 by firstly utilizing the linkage rod 6 to be connected with the valve core 11 on the valve seat 8 and then utilizing the bottom shell 32 to penetrate through the linkage rod 6 and then be connected with the valve core 11; then, the dial 31 is installed on the bottom shell 32, and finally, the linkage rod 6 is rotated, when the driving part 5 is contacted with the driven part 33, the numerical value on the dial 31 is promoted to be increased or decreased by one unit, so that the recording of the rotation number of the valve core 11 is realized.

In conclusion, the device can accurately record the rotation number of the valve core 11, so that a user can accurately control the flow rate of the medium.

In addition, the device not only can accurately grasp the rotation number of the valve core 11 in time, but also can accurately control the flow rate of the medium.

In order to ensure the counting accuracy of the counter 3, a support platform 310 is arranged on one surface of the bottom shell 32, and a shaft pin hole 37 penetrating through the bottom shell 32 is further arranged on one side of the support platform 310; according to the scheme, firstly, the linkage rod 6 and the dial 31 are eccentrically arranged, so that the driving part 5 on the linkage rod 6 can only contact with the driven part 33 at a certain moment, and the increase and decrease of numerical units are realized; when the linkage rod 6 continues to rotate, the driving part 5 can be separated from the driven part 33 due to the eccentric arrangement, and the increased and decreased numerical value can stay at the preset position.

Due to this, the device realizes the accurate record of numerical value through simple mechanical structure, has both reduced data acquisition's cost, can realize the rotation number of turns of accurate collection case 11 again.

Further, a boss 38 is further disposed at the center of the supporting platform 310; wherein, the dial plate 31 is inserted into the boss 38, so that the dial plate 31 rotates along the outer circumference of the boss 38. Due to the arrangement of the boss 38, the round hole in the dial 31 can be sleeved on the boss 38, and when the linkage rod 6 drives the dial 31 to rotate, the dial 31 can stably rotate along the boss 38, so that the problem that the dial 31 can not accurately record data due to position deviation is solved.

In order to facilitate efficient and stable assembly of the counter 3 on the valve seat 8, one side of the bottom case 32, which is far away from the dial 31, is further provided with straight teeth 36, and the straight teeth 36 are connected with the valve seat 8, wherein the valve seat 8 is further provided with tapered teeth 4 which are in adaptive connection with the straight teeth 36, so that the bottom case 32 is connected with the valve seat 8. Through the scheme, the counter 3 and the valve body 1 are assembled by guiding the counter 3 to be assembled with the valve seat 8 through the conical teeth 4 before assembly; after the counter 3 is assembled with the valve seat 8, the position of the counter 3 is kept stable, and particularly, the problem that the counter 3 axially rotates on the valve seat 8 can be effectively solved after the straight teeth 36 are contacted with the tapered teeth 4.

Further, still be equipped with slot 39 on the drain pan 32, insert through the rand 7 that is equipped with behind slot 39, will drain pan 32 further fixes on valve seat 8, utilize rand 7 to insert in slot 39, rand 7 with counter 3 further fix on valve seat 8, utilize the card of rand 7 to go into or take out simultaneously, be convenient for again counter 3 and valve seat 8 fixed with take off.

Besides, the whole counter 3 is pulled upwards until the conical teeth 4 are separated from the straight teeth 36, and then the counter rotates along the circumference of the valve core 11, so that the position of the counter 3 can be freely adjusted.

In order to further ensure that the dial plate 31 stably rotates on the boss 38, so as to avoid axial runout of the dial plate 31 and influence on data recording; the dial plate is characterized by further comprising an upper cover 30, and the dial plate 31 is fixed on the bottom shell 32 through the closing of the upper cover 30 and the bottom shell 32.

To further facilitate the user's access to the data, the cover 30 is also provided with a viewing window 34.

Because the linkage rod 6 passes through the support column 35 arranged on the upper cover 30 and then is connected with the spiral cover 2 arranged on the upper cover, the linkage rod 6 can rotate more conveniently, and meanwhile, the mutual combination of the spiral cover 2, the upper cover 30 and the bottom shell 32 can ensure the stable work of the counter 3 and optimize the external structure of the device, especially, the cross sections of the bottom shell 32 and the upper cover 30 are set to be oval, so that the internal space of the counter 3 under the condition of unchanged overall height is enlarged, and the internal structure layout of the counter 3 is more facilitated.

In order to improve the transmission efficiency, the driven portion 33 is provided in a groove shape, and the driving portion 5 is provided in a rack shape.

Because both ends of the valve body 1 are provided with the pressing caps 10, the fastening sleeve 9 arranged on the valve body 1 is fixed through the pressing caps 10, and the fastening sleeve 9 is made of 316 stainless steel. Therefore, the problem that the existing fastening sleeve 9 is easy to oxidize and rot when meeting water is solved, so that the device is durable, quick to operate and low in cost, and the counter 3 can rotate at the valve seat 8 according to the requirement.

In conclusion, the device solves the problems that the number of turns of the traditional product is unclear and the operation is complicated, and meanwhile, the fastening sleeve 9 of the device is made of 316 stainless steel, so that the fastening sleeve 9 is firm and durable.

Since the high device can directly display the recorded data through the observation window 34, the user can know the airflow data more quickly and conveniently, and the operation time is shortened.

How to open the valve body 1 by the valve core 11 is the prior art and is not described herein again.
