Description
The utility model is a kind of gas water-heater inlet valve, is for the matching used water supply piping of gas water-heater fitting device, and the inlet valve that also can be used as other water heaters uses.
In the prior art, general gas water-heater does not all have supporting inlet valve, just adopts the angle valve of outsourcing to mix the flexible pipe that is made of protective metal shell and plastic tube and is installed and connected in the gas water-heater water intake.Its shortcoming is: install pretty troublesome; Pipe joint place and valve member usually cause water clock because of poor sealing; Supporting not attractive in appearance with gas water-heater; And because valve member is realized lifting by screw thread, open and close inconvenience during use is difficult to realize quick closing valve and opens soon; And the plastic tube material in the flexible pipe is thermo-labile, cold-resistant and do not press, cause explosion, influence is used.
The purpose of this utility model be to avoid deficiency of the prior art and provide that a kind of installation is simple and convenient, favorable sealing property, easy to use, open and close efficiently, with gas water-heater or the matching used attractive and durable gas water-heater inlet valve of other water heaters.
The purpose of this utility model can reach by following measure: the gas water-heater inlet valve as shown in Figure 1, include the ball valve that constitutes by valve body (4), ball valve core (6), handgrip (7), capping (8), attachment screw (9), valve rod (10) and connection block (13), to reach rapid switching purposes; It is characterized in that also including: a. is provided with intake pipe (18) at connection block (13) feed-water end, intake pipe (18) compresses zero shape rubber ring (16) by the plug screw (17) in the screw-in nut (15) and is clamped in the pore of nut (15), make intake pipe (18) need not add connection pipe fitting (as flange) or process the inner and outer pipe screw thread and can directly be connected with ball valve, and be convenient to require (as horizontal position) to cut the length that intake pipe (18) connects valve portion according to desired location, can guarantee the sealing of intake pipe (18) outer wall simultaneously; Nut (15) is connected with connection block (13), make intake pipe (18) and ball valve constitute overall structure, between the interior edge face of nut (15) and connection block (13) feed-water end end face, rubber gasket (14) is housed, to guarantee the sealing of nut (15) and connection block (13) joint; B. be provided with screwed pipe joint (21) in the water inlet end of intake pipe (18), intake pipe (18) compresses zero shape rubber ring (20) by the plug screw (19) in the screw-in screwed pipe joint (21) and is clamped in the pore of screwed pipe joint (21), make intake pipe (18) be convenient to be connected with the water supply piping, and can require (as the vertical position) to cut the length of this part of intake pipe (18) according to desired location, can guarantee to be positioned at simultaneously the sealing of intake pipe (18) outer wall of joint; C. be provided with coupling nut (1) in the water outlet end of valve body (4), coupling nut (1) is enclosed within on the valve body (4) and by being contained in snap ring (3) axially locating of the annular groove on the valve body (4), so that with the connection of gas water-heater water intake, a side end face and valve body (4) waterexit end end face that rubber gasket (2), rubber gasket (2) are housed in the endoporus of coupling nut (1) join, with the sealing of assurance with gas water-heater water intake joint.
The utility model is described in further detail to utilize accompanying drawing:
Fig. 1 is the structural representation of a kind of gas water-heater inlet valve of the present utility model.
In the gas water-heater inlet valve of Fig. 1, (1) is coupling nut, (2) be rubber gasket, (3) be snap ring, (4) be valve body, (6) be the ball valve core, intake more reliably and close water for guaranteeing ball valve core (6), can be provided with politef seal washer (5 in ball valve core (6) both sides, 12), seal washer (5) is contained in valve body (4) inner chamber, seal washer (12) is contained in joints sleeve (13) by valve body one side end, seal washer (5,12) sphere with ball valve core (6) keeps in touch, its endoporus communicates at the endoporus of on state with ball valve core (6); (7) be that handgrip, (8) are that capping, (9) are attachment screws; (10) be valve rod, for guaranteeing the sealing of valve rod (10) in valve body (4), preventing seepage, and be convenient to valve rod (10) when work and in valve body (4), locate, zero shape rubber seal (11) can be set on valve rod (10), 2 roads, zero shape rubber seal (11) generally can be set reach requirement; (13) be that connection block, (14) are that rubber gasket, (15) are that nut, (16) are that zero shape rubber ring, (17) are that plug screw, (18) are that intake pipe, (19) are that plug screw, (20) are that zero shape rubber ring, (21) are screwed pipe joints.
The intake pipe of a kind of gas water-heater inlet valve of the present utility model (18) can be Stainless Steel Tube or chrome-plated steel; Can also adopt the metallic sheath flexible pipe, this metallic sheath flexible pipe is by protective metal shell and adopt flexible pipe heat-resisting, cold-resistant and that withstand voltage rubber plastic blending material is made to constitute.
