Abstract
The invention discloses a valve with a valve cover self-locking structure. The valve comprises a valve body and a valve cover. A connecting pipe opening with an internal thread is arranged in the valve body. A connector with an external thread is arranged on the valve cover. The valve body and the valve cover are connected together through the threads. First inverted teeth are arranged at the front end of the connector, second inverted teeth matched with the first inverted teeth are arranged in the connecting pipe opening, and the connector is screwed in the connecting pipe opening till the first inverted teeth and the second inverted teeth are buckled. By means of the structure of the inverted teeth, the valve cover cannot retreat in a reversing rotating manner; the valve cover and the valve body are connected more firmly and reliably and cannot loosen or fall out during testing; and the detection yield is increased, and resource waste is reduced.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of valve with valve gap self-locking structure.
Background technique
Existing valvular valve gap is generally be threaded connection on valve body, and valve needs to test before producing, and in test process, part valve gap can rotate backward and exit screw thread in vibrations, thus get loose and drop out, make valve not by test, become defective products, cause the waste of resource.
Summary of the invention
In order to overcome above-mentioned technical problem, the object of the present invention is to provide a kind of valve with valve gap self-locking structure, valve gap is automatically locked after connecting, and avoids it to rotate backward and get loose dropping out, and makes valve can pass through test smoothly.
The technical solution adopted in the present invention is:
A kind of valve with valve gap self-locking structure, comprise valve body, valve gap, the tapped connection mouth of pipe is provided with in described valve body, described valve gap is provided with the externally threaded connecting head of band, valve body and valve gap are together by a threaded connection, described connecting head front end is provided with the first pawl, is provided with the second pawl matched with the first pawl in the described connection mouth of pipe, and described connecting head is screwed into and connects the mouth of pipe until the first pawl and the second pawl fasten mutually.
As the further improvement of technique scheme, be provided with plastic core in described valve body, described second pawl is arranged in plastic core.
The invention has the beneficial effects as follows:
The present invention makes valve gap counterrotating not exit by the structure of pawl, and the connection of valve gap and valve body is more solid and reliable, and also can not get loose in testing drops out, and improves the up-to-standard rate detected, and reduces the wasting of resources.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is decomposition texture schematic diagram of the present invention;
Fig. 2 is the perspective view of valve gap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
With reference to Fig. 1, Fig. 2, a kind of valve with valve gap self-locking structure provided by the invention, comprise valve body 1, valve gap 2, plastic core is provided with in described valve body 1, the tapped connection mouth of pipe 11 is provided with in described valve body 1, described valve gap 2 is provided with the externally threaded connecting head 21 of band, valve body 1 and valve gap 2 are together by a threaded connection, described connecting head 21 front end is provided with the first pawl 211, the second pawl 111 matched with the first pawl 211 is provided with in the described connection mouth of pipe 11, second pawl 111 is arranged in plastic core, described connecting head 21 is screwed into and connects the mouth of pipe 11 until the first pawl 211 and the second pawl 111 fasten mutually.The present invention makes valve gap 2 counterrotating not exit by the structure of pawl, and valve gap 2 is more solid and reliable with the connection of valve body 1, also can not get loose in testing and drop out, and improves the up-to-standard rate detected, and reduces the wasting of resources.
Above concrete structure and sized data illustrate preferred embodiment of the present invention, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
