Abstract
The utility model relates to a hermetically sealed construction for an electric water heater safety valve. The hermetically sealed construction is mainly structured as that ring grooves are opened on the screwed wall of a pressure regulating cap with a center circular hole and in a valve port of a safety valve pressure relief chamber, an O-shaped obturating ring is arranged in the ring groove, and an O-shaped ring is arranged between the wall of the center circular hole and a pull rod. Hereby effective seal between the pressure regulating cap and the valve body and between the pressure regulating cap and the pull rod can be guaranteed in the rotating and sliding process. Compared with the prior art, the hermetically sealed construction not only dispenses with the sealed cap arranged in the valve port, but also is convenient for people to regulate the water pressure, therefore the hermetically sealed construction has the advantages of simpler structure, more convenient operation and better leak tightness.
Description
The utility model relates to the sealing configuration of using on a kind of electric water heater safety valve.
Existing electric water heater safety valve all is with and is used the pressure regulation cap, can adjust and limit pressure in the water heater.When hydraulic pressure surpassed the limit of setting, the safety precaution effect was played in the automatic draining of safety valve meeting.In order to prevent that the pressure regulation cap from leaking, it is 99253097 that State Intellectual Property Office announced the patent No. on September 27th, 20000, name is called the patent of " the pressure regulation sealing configuration of electric water heater safety valve ", and it is provided with a sealing configuration of being made up of sealed cap, rubber washer in the end of safety valve.Although this sealing configuration good airproof performance, component are many, and cost has improved, and install, use inconvenient.
The purpose of the utility model is to be at the problems referred to above, provides a kind of simple in structure, easy to adjust, the electric water heater safety valve pressure regulation sealing configuration that sealing is good again.The technological scheme of its solution is such: it mainly in the valve body port that is positioned at the safety valve pressure-releasing chamber, have on the pressure regulation cap thread wall of center hole and offer ring recess, in ring recess, load onto O-ring seals; O shape circle is housed between center hole hole wall and pull bar.Like this, can guarantee sealing effectively in spiral, sliding process between pressure regulation cap and valve body, the pull bar, this had both saved the sealed cap that is contained in the valve body port, had made things convenient for the adjustment of people to hydraulic pressure again.Therefore, it compared with prior art, it is more simple to have structure, use more convenient, advantages such as better tightness.
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
Fig. 1 is the schematic representation that has the electric water heater safety valve of this pressure regulation sealing configuration.
Fig. 2 is the schematic representation of this sealing configuration.
Fig. 3 is the schematic representation of the another kind of sealing configuration of the utility model.
Referring to Fig. 1, Fig. 2, the electric water heater safety valve that has this real new structure is communicated with the inner bag of water heater, and it comprises one-way valve 1 and Decompression valves; Decompression valves is made up of parts such as valve body 3, mangetic core assembly 2, stay column 6, spring 4, pressure regulation cap 9, handles 10; Have water outlet 5 on the valve body 3 at Decompression valves position, stay column 6 connects together with mangetic core assembly 2, and under the effect of spring 4 Decompression valves cuts out.Generally speaking, the hydraulic pressure of water heater liner is lower than rating value, and Decompression valves cuts out all the time.In case the vapour pressure in the water heater liner surpasses setting value, mangetic core assembly 2 moves under the effect of vapour pressure power, the Decompression valves conducting, and current can flow out from the water outlet 5 of Decompression valves.Pressure regulation cap 9 connects with valve body 3 by screw thread, rotation pressure regulation cap 9, and pressure that can 4 pairs of mangetic core assemblies 2 of Regulation spring, thus can change the vapour pressure size that makes the Decompression valves conducting.When needs manual unlocking Decompression valves,, mangetic core assembly 2 displacements are got final product as long as pull handle 10.In order to guarantee the sealing between pressure regulation cap 9 and valve body 3, the stay column 6, on pressure regulation cap 9 threaded walls, open ring recess, O-ring seals 8 is housed in the ring recess; On pressure regulation cap 9 center holes 11 hole walls, open ring recess, also load onto O shape circle with matching, like this, can reach the effective sealing between pressure regulation cap and valve body, the stay column, also can omit sealed cap simultaneously, make when regulating pressure, directly rotate the pressure regulation cap and get final product.
Structure of the present utility model can also be embedded in O shape circle 7 on the stay column 6 lip-deep ring recess, referring to Fig. 1; Can play the effect between sealing pressure regulation cap 9 and the stay column 6 like this, equally.Can also use two O shape circles 7 to seal on the stay column 6 according to actual needs.
Claims (2)
1, a kind of electric water heater safety valve pressure regulation sealing configuration, it comprise spiral in safety valve valve body (3) port, have a pressure regulation cap (9) of center hole (11), it is characterized in that: have ring recess on pressure regulation cap (9) threaded walls, O-ring seals (8) is housed in the ring recess, center hole (11) matches with the diameter of stay column (6), and O shape circle (7) is housed therebetween.
2, according to the described electric water heater safety valve pressure regulation of claim 1 sealing configuration, it is characterized in that: described pressure regulation cap (9) circular hole (11) hole wall or pull bar (6) surface are provided with ring recess, and O shape circle (7) is positioned at ring recess.
