Abstract
The utility model provides a connection sluice valve for copper threads, which can prevent a medium from corroding connection threads between a valve body and a valve cover, and comprises the valve body with a water inlet and a water outlet at two ends, the valve cover connected with the valve body in a sealing mode, a valve rod connected with the valve cover through the threads and a flashboard which is connected to the lower end of the valve rod, arranged in a valve cavity of the valve body and contacted with a valve seat in sealing mode. The valve cover is connected with external threads on the valve body through internal threads, and a gasket is arranged between the inner bottom face of the valve cover and the end face of the position of the valve body with the external threads.
Description
Technical field
The utility model relates to a kind of gate valve, specifically, is a kind of copper lock that is threaded.
Background technique
Existing copper gate valve, valve body and valve gap connection part adopt general thread connecting mode, and valve body contacts with medium with connecting thread between the valve gap inevitably, has caused the corrosion of medium to connecting thread.
Summary of the invention
The purpose of the utility model provides a kind of medium of can avoiding valve body and connecting thread between the valve gap is caused the copper of the corrosion gate valve that is threaded.
This copper gate valve that is threaded; Comprise that two ends have the valve body of water intake and water outlet; The valve gap that links to each other with valve seal with the valve rod of valve gap through being threaded, is connected the flashboard that contacts with valve base sealing of the valve pocket valve rod lower end, that be positioned at valve body; Valve gap links to each other with outside thread on the valve body through internal thread, at the inner bottom surface of valve gap and have between the end face at externally threaded valve body place packing ring is set.
The beneficial effect of the utility model: because at the inner bottom surface of valve gap and have between the end face at externally threaded valve body place packing ring is set; Packing ring has prevented that effectively medium from arriving the connecting thread place between valve body and the valve gap through packing ring, has avoided the corrosion of medium to said screw thread.
The above-mentioned copper gate valve that is threaded, flashboard is provided with the flashboard rubber seal that is connected with valve base sealing.Preferred flashboard adopts Cuprum alloy, vulcanizes with flashboard rubber seal connection and presses EPDM rubber.Flashboard adopts Cuprum alloy, and EPDM rubber is pressed in the sulfuration of sealing surface place, can either guarantee the cementability between flashboard rubber seal and the flashboard matrix, and in use unlikely coming off simultaneously owing to having adopted rubber seal, thereby guarantees that product is easy to realize zero leakage.
The above-mentioned copper gate valve that is threaded, the vacancy is provided with filler in the valve gap upper end, on the gland that is used to compress filler and the valve gap through being threaded.Guarantee the sealing between valve rod and the valve gap like this.
Description of drawings
Fig. 1 is the schematic representation of the utility model.
Embodiment
Referring to the copper shown in Figure 1 soft sealing gate valve that is threaded, between valve gap 6 and the valve body 1 through being threaded; Connect through trapezoidal thread between flashboard 2 and the valve rod 4; When handwheel 11 rotations, drive valve rod 4 and rotate, valve rod 4 drives flashboard 2 through trapezoidal thread and moves up and down, thereby realizes the open and close of gate valve.Collar 7 is arranged on the interior bottom of valve gap 6.Positioning ring platform on the valve rod 4 prevents that valve rod from moving axially between valve gap and collar.
Seal through PTFE packing ring 5 between valve gap 6 and the valve body 1; Valve body 1 does not contact with medium with connecting thread between the valve gap 6, can prevent the corrosion of medium to connecting thread.The nut 10 of screwing compresses PTFE filler 8 by gland 9, guarantees the sealing between valve rod and the valve gap.
Flashboard 2 adopts Cuprum alloy; EPDM rubber is pressed in the sulfuration of sealing surface place, can either guarantee the cementability between flashboard rubber seal 3 and the flashboard matrix, in use unlikely coming off; Simultaneously owing to adopted rubber seal, thereby guarantee that product is easy to realize zero leakage.
Claims (4)
1. the copper gate valve that is threaded; Comprise that two ends have the valve body of water intake and water outlet; The valve gap that links to each other with valve seal with the valve rod of valve gap through being threaded, is connected the flashboard that contacts with valve base sealing of the valve pocket valve rod lower end, that be positioned at valve body; It is characterized in that: valve gap links to each other with outside thread on the valve body through internal thread, at the inner bottom surface of valve gap and have between the end face at externally threaded valve body place packing ring is set.
2. like the claim 1 copper gate valve that is threaded, it is characterized in that: flashboard is provided with the flashboard rubber seal that is connected with valve base sealing.
