Abstract
The utility model relates to a unilateral safety relief valve that is applied on the water inlet pipe connector that is connected with the water heater, which pertains to the technical field of control device. A valve core groupware is arranged in a plastic valve body and a pulling rod is arranged on a permanent seat, while a spring is arranged on the pulling rod and is fixed on the plastic valve body through a cross slot and a copper seat is arranged on the plastic valve body. The utility model is characterized in that: a pressure spring and a laminate are arranged on the valve core groupware and the laminate is fixed on the plastic valve body. The utility model is compact and reasonable in structure; as the valve body is formed by applying the transparent high intensity plastic at one time, the inner wall and stream guidance are smooth and corrosion resistance is good; light weight, low manufacturing cost and simple processing technique; to produce the convolution status of water current, have no abnormal sound during the working process and be convenient for promoting and applying.
Description
Technical field:
The utility model relates to a kind of unidirectional safety relief valve, is used to be connected the water inlet tube of water heater interface, belongs to the safety control technical field.
Background technique:
Water heater is being extensive use of by people, but in water heater, inevitably can leave air or the electric heating tube temperature controlling device is out of control, air expansion or drying after heating, after installing unidirectional Decompression valves additional, safety valve is opened pressure release under certain pressure, will guarantee that water heater does not explode because of overpressure.Before the utility model was made, in prior art, this Decompression valves mainly was made up of parts such as valve body, mangetic core assembly, pull bar, spring, stage clip, copper seats.Its valve body adopts copper product punch forming, Heavy Weight, processing technology complexity; And long flow path, quality of product is difficult to guarantee that cost is higher.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of compact structure is provided, rationally, and low cost of manufacture; Main body inner wall is smooth, and water conservancy diversion is smooth and easy, good corrosion resistance; Steady quality, the tranquil unidirectional safety relief valve that has no abnormal sound in the working procedure.
Main solution of the present utility model is achieved in that
It mainly adopts the utility model in plastics valve body 1 mangetic core assembly is housed, pull bar 16 is installed on the fixed base 9, spring 10 is installed on the pull bar 16, adopt cross recess 11 to be fixed on the plastics valve body 1, copper seat 12 is spun on the plastics valve body 1, it is characterized in that adopting stage clip 5, flower sheet 6 are installed on mangetic core assembly, flower sheet 6 is fixed on the plastics valve body 1.
Compared with the prior art the utility model has the following advantages:
The utility model compact structure, rationally; Because valve body adopted transparent highstrenghtpiston to process once-through, its inner wall smooth, water conservancy diversion is smooth and easy, and can produce the current state that circles round, good corrosion resistance; In light weight, low cost of manufacture, processing technology is simple; When water inlet place is cut off the water supply, can guarantee that water does not outflow in the water heater, calmness has no abnormal sound in the working procedure, and can come into plain view to its working state, and is easy to utilize.
Description of drawings:
Fig. 1 is the utility model structural representation;
Embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts rubber washer 2, rubber seat 3, spool 7, volute spring 4 to form mangetic core assembly.Mangetic core assembly is installed in the plastics valve body 1, and stage clip 5, flower sheet 6 are installed on mangetic core assembly, and flower sheet 6 directly is fixed on the plastics valve body 1, and employing is threaded.Pull bar 16 is installed on the rubber fixed base 9, and loads onto rubber seal 8, and spring 10 is installed on the pull bar 16, adopts cruciform slot screw 11 to fasten on plastics valve body 1.O type circle 13 is housed on sealed copper seat 12, and rubber band 14 is spun on the plastics valve body 1.Pad 15 is enclosed within on the pull bar 16, reinstalls handle 18, adopts rivet 17 fixing.Main body valve body 1 adopts the high-strength engineering plastic injection molded in the utility model, and the intake pipe 19 on its valve body 1 is made plum blossom shape, and current can only unidirectionally be entered, and stops the water after heating to reflux.The utility model is installed on the water inlet tube of water heater, and water heater also can descend pressure by manual pressure release fast.
