Embodiment approach

[0028] When using dustproof, put the upper and lower parts of the dust cover 10 at the corresponding position of the valve, insert the iron nail 11 into the cavity 6, and the two symmetrical iron balls 12 are located around the iron nail 11, when the iron nail 11 After the concave ring of the concave ring enters the cavity 6, the iron ball 12 just gets stuck in the concave ring, plays the role of fixing the iron nail 11, and locks the upper and lower parts of the dust cover 10 together; when the dust cover is to be opened, It is necessary to hold the iron nail 11 near the bottom of the dustproof cover 10 with a powerful magnet so that it is separated from the cavity 6 . This not only plays the role of dust prevention, but also plays the role of anti-theft.

[0029] When the valve needs to be opened, the dust cover 10 is removed, and the valve handle 3 is put into the empty groove 9, and the first magnetic block 8 is attracted by the second magnetic block 7, which also has a la...

Abstract

The invention discloses a dustproof and antitheft valve, comprising a valve body (1), a valve rod (2) and a valve element (4); the dustproof and antitheft valve is characterized by further comprising a valve handle (3) separating from the valve rod (2) and a dustproof shade (10) at the periphery of the valve body (1); the dustproof shade (10) is covered at the periphery of the valve body (1) by a locking device; the locking device comprise an iron nail (11) below the dustproof shade (10) and a cavity (6) above the dustproof shade (10); a concave ring is arranged at the middle part of the iron nail (11); a spring (13), an iron block (14) and an iron ball (12) are placed in the cavity (6) from top to bottom. The dustproof and antitheft valve plays roles in dust collection and guard against thefts and is labor-saved.

Description

technical field [0001] The invention relates to pipeline connection equipment, in particular to a dust-proof and anti-theft valve. Background technique [0002] Due to the loosening of the valve stem or the fastening device on the valve body of the valve located outdoors, coupled with the harsh outdoor environment, such as sewage, dust, etc. will seep into the pipeline through the gap, resulting in the contamination of the medium in the pipeline, and the valve stem of the valve will also be damaged. It will be opened by mistake or maliciously opened and closed, resulting in the loss of the medium in the pipeline, such as tap water, and greatly affecting people's lives. Therefore, it is necessary to design a dust-proof and anti-theft valve to protect the medium in the pipeline from pollution and theft. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a dust-proof and anti-theft valve, ...
