Abstract
The utility model provides a novel joint check valve simple in structure. The novel joint check valve comprises a valve body, a valve element and a valve cover. The valve element is arranged in the valve body, and the two ends of a valve rod in the middle are arranged on the valve body and the valve cover respectively in a sleeved mode. One end of the valve body is arranged on the valve cover in a sleeved mode, and external threads are arranged at the other end of the valve body. One end of the valve cover is connected with the valve body, the other end of the valve cover is in sliding connection with a water meter joint nut in a sleeved mode, the valve rod between the valve element and the valve cover is sleeved with a conical return spring, a check ring is arranged at the non-valve body connecting end of the valve cover, and a sealing ring is arranged in the water meter joint nut. Compared with a general water meter connecting system, the external threads are arranged at the non-valve cover connecting end of the valve body to replace a nipple joint, and a nipple joint structure is omitted; the valve cover is sleeved with the water meter joint nut, the check valve is combined with a water meter joint, and a water meter joint structure is omitted; the overall structure is simplified, materials are saved, mounting and use are convenient, the water leakage probability is low, and safety coefficients are higher.
Description
Technical field
The utility model relates to valve field, and what especially relate to is a kind of Novel joint safety check.
Background technique
Traditional water meter connected system is generally gate valve, Threaded Connector Coupling, safety check, watermeter connector and water meter is connected to form successively, the product that whole system need to connect is more, system complex, and cost is high, and multiple annexations cause leak probability increase, safety coefficient is low.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of Novel joint safety check simple in structure is provided.
For achieving the above object, technical solution of the present utility model is: Novel joint safety check, comprise valve body, spool and valve gap, and described spool is located at valve inner, and the two ends of its valve rod are socketed in respectively on valve body and valve gap; One end of described valve body is socketed on valve gap, and the other end is provided with outside thread; One end of described valve gap connects valve body, and the other end flip sleeve is connected to watermeter connector nut.
Preferably, between described spool and valve gap, be provided with taper return spring.
Preferably, the end of the non-valve body connecting end of described valve gap is provided with back-up ring, and the inside of described watermeter connector nut is provided with seal ring.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: the utility model is with respect to general water meter connected system: the non-valve gap connecting end of valve body is provided with outside thread and replaces Threaded Connector Coupling, omit Threaded Connector Coupling structure; On valve gap, be socketed watermeter connector nut, safety check and watermeter connector are merged, omit watermeter connector structure; Overall structure is simplified, and saves material, easy to install, and the probability that leaks reduces, and safety coefficient is higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Main description of reference numerals:
Valve body 1 spool 2
Valve gap 3 watermeter connector nuts 4
Outside thread 11 valve rods 21
Taper return spring 22 back-up rings 31
Seal ring 41.
Embodiment
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Novel joint safety check of the present utility model, comprise valve body 1, spool 2 and valve gap 3, described spool 2 is located at the inside of valve body 1, the two ends of its middle part valve rod 21 are slidably socketed respectively at the middle part of valve body 1 and valve gap 3, on the valve rod between described spool 2 and valve gap 3, are socketed with taper return spring 22; One end of described valve body 1 is socketed on valve gap 3, and the other end is provided with the outside thread 11 for connecting other valves; One end of described valve gap 3 connects valve body 1, the other end flip sleeve is connected to watermeter connector nut 4 and is provided with back-up ring 31 in end, back-up ring 31 is deviate from for preventing water meter nut 4 joints, and the internal sleeve of described watermeter connector nut 4 is provided with seal ring 41, after connecting water meter, seals.
Above-described, be only preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
