Description

Technical Field

[0001] The utility model belongs to the technical field of valve installation, in particular to a valve anchor bolt with a new structure. Background Art

[0002] After the valve is installed, it needs to be fixed with anchor bolts to prevent the valve from vibrating and moving during operation. Under normal circumstances, the valve is lifted vertically when it is installed, disassembled and adjusted. The anchor bolts adopt the national standard form, such as Figure 1 The bypass valve basic installation diagram shown is given. In actual application, some valves do not have enough space to be lifted upward. When installing, the valve is hoisted to the basic accessories and then moved horizontally to the installation position. When disassembling, it must also be moved horizontally before being lifted vertically.

[0003] The most typical installation is the vent valve, its structure is as follows Figure 2 The vent valve foundation installation diagram shown in the figure is given. The fairing is poured on the concrete wall in the early stage. If conventional anchor bolts are used, it will be difficult to disassemble and install due to limited space. Therefore, we propose a new structure of valve anchor bolts. Utility Model Content

[0004] In order to solve the problem that when conventional anchor bolts are used during the installation of current valves, disassembly and installation are difficult due to limited space, the utility model provides the following technical solution: a valve anchor bolt with a new structure, comprising a long screw rod, a connector and a short stud, wherein the long screw rod and the short stud are detachably connected via the connector, and the top end of the short stud can be sleeved with a washer and a nut can be detachably installed.

[0005] Preferably, the upper portion of the long screw and the lower portion of the short stud are both provided with a first external thread, and the connector is provided with an internal thread, and the first external thread and the internal thread match in size and can be detachably threaded together.

[0006] Preferably, the upper portion of the long screw and the lower portion of the short stud are both provided with a hexagonal head, and the connector is provided with an inner hexagonal socket, and the hexagonal head and the inner hexagonal socket match in size and can be detachably plugged together.

[0007] Preferably, a second external thread is provided on the circumference of the long screw rod, and the provision of the second external thread facilitates screwing in the long screw rod.

[0008] Preferably, a cone head is provided at the lower end of the long screw rod, and the provision of the cone head facilitates screwing in the long screw rod.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] Before installing the valve, the short stud can be taken out first. After the valve falls into the correct position, the short stud can be installed. First, the cone head of the long screw can be screwed down into the installation position, and then the connector and the short stud can be installed to fix them. Subsequently, washers and nuts can be installed to fix them. This is used in situations where the valve installation space is limited, solving the problem of valve installation and disassembly in certain specific environments.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Example 1, see Figure 1-3The invention comprises a long screw rod 1, a connector 2, and a short stud 3. The top of the short stud 3 can be sleeved with a washer and a nut can be detachably installed. A first external thread 4 is provided on the upper portion of the long screw rod 1 and the lower portion of the short stud 3. An internal thread 5 is provided within the connector 2. The first external thread 4 and the internal thread 5 match in size and can be detachably threaded together, so that the long screw rod 1 and the short stud 3 are detachably connected through the connector 2. A second external thread 8 is provided circumferentially of the long screw rod 1, and a tapered head 9 is provided at the lower end of the long screw rod 1.

[0021] Example 2, see Figure 4 The upper part of the long screw 1 and the lower part of the short stud 3 are both provided with a hexagonal head 6, and an inner hexagon 7 is provided in the connecting body 2. The hexagonal head 6 and the inner hexagon 7 match in size and can be detachably plugged together, so that the long screw 1 and the short stud 3 are detachably connected through the connecting body 2. A second external thread 8 is provided in the circumference of the long screw 1, and a cone head 9 is provided at the lower end of the long screw 1.

[0022] Working principle: Before installing the valve, the short stud 3 can be taken out first, and then the short stud 3 can be installed after the valve falls into the correct position. First, the cone head 9 of the long screw 1 can be screwed down into the installation position, and then the connector 2 and the short stud 3 are installed to fix them. In Example 1, the connector 2 is spirally connected to the top of the long screw 1, and then the short stud 3 is spirally installed on the connector 2. In Example 2, the connector 2 is sleeved on the top of the long screw 1, and then the short stud 3 is inserted into the connector 2, and then the gasket and nut are installed to fix it. It is used in situations where the valve installation space is limited, and solves the problem of valve installation and disassembly in certain specific environments.
